1. | Power System Stability Improvement of Long Transmission Line
System by Using Static Var Compensator (SVC)
Power System Stability Improvement of Long Transmission Line System by Using Static Var Compensator (SVC)Abstract: Power system stability is defined as the ability of power system to preserve it's steady stability or recover the initial steady state after any deviation of the system's operation. This paper will discuss how SVC has successfully been applied to control dynamic performance of transmission system and regulate the system voltage effectively. Present time power systems are being operated nearer to their stability limits due to economic and environmental reasons. Maintaining a stable and secure operation of a powersystem is therefore a very important and challenging issue. Shunt FACTS devices play an important role in improving the transient stability, increasing transmission capacity and damping low frequency oscillations. In this paper shunt FACTS device-SVC is used in a two area power system for improving the power system stability. MATLAB software has been used in this study.Key words: FACTS, long transmission line, MATLAB, SVC, power system stability, three phase fault.

Collision Free Intelligent Bloom Join Filters
Collision Free Intelligent Bloom Join FiltersAbstract: In operation research, there is no single method available for solving all optimization problems. Hence a number of techniques have been developed for solving different types of optimization problems. Optimization is the act of obtaining the best result under given circumstances. The ultimate goal of optimization is either to minimize the efforts required or to maximize the desired benefit [5]. Query Optimization is one of the optimization problems in database management system. It is a process of determining the most efficient way to execute a given query by considering the possible query plans. The approach suggested in the paper is mainly focused on join operation of the query. Previous work done was based on semi-join approach for query optimization but a semi-join needs more local processing such as projection and higher data transmission. To improve the previous approach, the filter based approach is utilized. The evaluation of filter is done by considering the collisions occurred, using perfect hash function and using sets of filters. Paper focuses on importance of optimization and Intelligent Bloom Join filter approach for data reduction in query optimization.Key words: Optimization; Query Optimization; Bloom Join; Bloom Filter Reference [1] B.

7. | A Noble Design of Energy Recovery Flip-Flops
A Noble Design of Energy Recovery Flip-FlopsAbstract: The power consumption of the clock tree dominates over 40% of the total power in high performance VLSI designs. Hence, low power clocking schemes are promising approaches for low power design. We propose energy recovery clocked flip-flops that enable energy recovery from the clock network, resulting in significant energy savings. These flip-flops operate with a single-phase sinusoidal clock which can be generating with high efficiency. In Cadence 180nm CMOS technology, we implemented these energy recovery clocked flip flops through an H tree clock network driven by a resonant clock generator to generate a sinusoidal clock. The proposed flip-flops exhibit more than 80% delay reduction, 47% power reduction, as compared to the conventional energy recovery flip-flop. Simulation results show a power reduction of 90% on the clock tree and total power saving of up to 80% as compared to the conventional square wave clocking schemes and flip flops. In this paper, we also propose clock gating solution for the energy recovery clocked flip flops reduces their power and delay. A pipelined array multiplier is designed which show a total power savings of 25%-69% as compared to the same multiplier using conventional square wave clocking scheme and corresponding flip-flops.Reference [1] M.

11. | Multidimensional Data Mining to Determine Association Rules in an Assortment of Granularities
Multidimensional Data Mining to Determine Association Rules in an Assortment of GranularitiesAbstract: Data Mining is one of the most significant tools for discovering association patterns that are useful for many knowledge domains. Yet, there are some drawbacks in existing mining techniques. The three main weaknesses of current data- mining techniques are: 1) rescanning of the entire database must be done whenever new attributes are added because current methods are based on flat mining using predefined schemata. 2) An association rule may be true on a certain granularity but fail on a smaller ones and vise verse. This may result in loss of important association rules. 3) Current methods can only be used to find either frequent rules or infrequent rules, but not both at the same time. This research proposes a novel data schema and an algorithm that solves the above weaknesses while improving on the efficiency and effectiveness of data mining strategies. Crucial mechanisms in each step will be clarified in this paper. This paper also presents a benchmark which is used to compare the level of efficiency and effectiveness of the proposed algorithm against other known methods. Finally, this paper presents experimental results regarding efficiency, scalability, information loss, etc. of the proposed approach to prove its advantages.Key words: Multidimensional Data Mining; Granular Computing; Apriori Algorithm; Concept Taxonomy; Association Rule Reference [1] Agrawal,R and Shafer, J.C, "Parallel mining of association rules", IEEE Transactions on Knowledge and Data Engineering, 8(6) (1996) 962-969.

Modeling And Experimental Analysis Of Generator In Vapour Absorption Refrigeration SystemAbstract: A breadboard prototype of an absorption system for refrigeration using heat from the exhaust-gases is to be designed, built and tested. In the commercial vapour absorption refrigeration system a heating coil generator system has been employed to vaporize the ammonia refrigerant. In the present work, the heating coil generator system has been replaced by the frame plate type heat exchanger. The exhaust gases from the IC engine have been utilized to vaporize the ammonia refrigerant. The available heat in the exhaust gases has to be estimated based on actual I.C-Engine driving cycles. The frame plate type heat exchanger has to be modeled and flow analysis inside the heat exchanger has to be analyzed. In addition, the recoverable energy of the exhaust gases is to be analyzed for representative Internal Combustion Engine..Key words: Absorption system, Ammonia-water, Exhaust gas, Internal combustion engine, Plate frame heat exchanger.

13. | Three Level Diode Clamped Inverter Fed Induction Motor with Dtc-Svm
Three Level Diode Clamped Inverter Fed Induction Motor with Dtc-SvmAbstract: This project presents a three-level diode-clamped inverter feeding an asynchronous motor drive with direct torque control (DTC). The control method is based on DTC operating principles. The stator voltage vector reference is computed from the stator flux and torque errors imposed by the flux and torque controllers. This voltage reference is then generated using a diode-clamped inverter, where each phase of the inverter can be implemented using a dc source, which would be available from fuel cells, batteries, or ultra capacitors. This inverter provides nearly sinusoidal voltages with very low distortion, even without filtering, using fewer switching devices. In addition, the multilevel inverter can generate a high and fixed switching frequency output voltage with fewer switching losses, since only the small power cells of the inverter operate at a high switching rate. Therefore, a high performance and also efficient torque and flux controllers are obtained, enabling a DTC solution for multilevel-inverter-powered motor drives. The Pulse Width modulation technique for an inverter permits to obtain three phase system voltages, which can be applied to the controlled output. Space Vector Modulation (SVPWM) principle differs from other PWM processes in the fact that all three drive signals for the inverter will be created simultaneously. The implementation of SVPWM process in digital systems necessitates less operation time and also less program memory. This project uses SVPWM technique for generation of pulses for three-level diode clamped inverter. Simulation is carried out on MATLAB-Simulink software..Key words: multilevel inverters, direct torque control, svpwm, induction motor Reference [1] Y.P.

Design and Implementation of Glitch-Free Phase Switching Plls to Suppress Quantization NoiseAbstract: A programmable frequency divider for quantization noise suppression in fractional- phase-locked loops is presented in this paper. The proposed phase switching Multi-modulus frequency divider (PS-MMFD) utilizes a novel glitch-free phase switching (PS) divide-by-0.5/1/1.5/2 cell to reduce the frequency division step to 0.5 and its QN induced by modulation is thus suppressed by additional 6 dB.

15. | Influence of Silica Fume on Normal Concrete
Influence of Silica Fume on Normal ConcreteAbstract: The incorporation of silica fume into the normal concrete is a routine one in the present days to produce the tailor made high strength and high performance concrete. The design parameters are increasing with the incorporation of silica fume in conventional concrete and the mix proportioning is becoming complex. The main objective of this paper has been made to investigate the different mechanical properties like compressive strength, compacting factor, slump of concrete incorporating silica fume. In this present paper 5 (five) mix of concrete incorporating silica fume are cast to perform experiments. These experiments were carried out by replacing cement with different percentages of silica fume at a single constant water-cementitious materials ratio keeping other mix design variables constant. The silica fume was replaced by 0%, 5%, 10%, 15% and 20% for water-cementitious materials (w/cm) ratio for 0.40. For all mixes compressive strengths were determined at 24 hours, 7 and 28 days for 100 mm and 150 mm cubes. Other properties like compacting factor and slump were also determined for five mixes of concrete.Key words: Silica Fume, Compressive Strength, Concrete, High performance concrete, Slump.

16. | Design of Aware Flip-Flop with Low Power Variations by P-Spice
Design of Aware Flip-Flop with Low Power Variations by P-SpiceAbstract: Excessive power dissipation causes overheating, which can lead multiple impacts like, packaging cost, reliability & functionality of IC and other soft errors. This naturally limits battery life of hand held equipments and need urgent solution to enable the proliferation of technology at large. Parameter variations in nanometer process technology are one of the major design challenges. They cause to be increased delay on the critical path and to change the logic level of internal nodes. The basic concept to solve these problems at the circuit level, design-for-variability (DFV), is to add error handling circuits at the conventional circuits so that they are robust to nanometer related variations. The state-of-the-art variation-aware flip flops are mainly evolved from aggressive DVFS (dynamic voltage and frequency scaling) -based low power application systems which handle errors caused from the scaled supply voltage. They only detect the timing errors and cannot correct the errors. We propose a variation–aware flip flop which can detect and correct the timing error efficiently.

17. | Effect of Artificial Roughness on Solar Air Heater: An Experimental Investigation
Effect of Artificial Roughness on Solar Air Heater: An Experimental InvestigationAbstract: It is well known, that, the heat transfer coefficient between the absorber plate and working fluid of solar air heater is low. It is attributed to the formation of a very thin boundary layer at the absorber plate surface commonly known as viscous sub-layer The heat transfer coefficient of a solar air heater duct can be increased by providing artificial roughness on the heated wall (i.e. the absorber plate) The use of artificial roughness on the underside of the absorber plate disturbs the viscous sub-layer of the flowing medium. It is well known that in a turbulent flow a sub-layer exists in the flow in addition to the turbulent core. The purpose of the artificial roughness is to make the flow turbulent adjacent to the wall in the sub-layer region. Experiments were performed to collect heat transfer and friction data for forced convection flow of air in solar air heater rectangular duct with one broad wall roughened by discrete v –groove & v- shape ribs. The range of parameters used in this experiment has been decided on the basis of practical considerations of the system and operating conditions. The range of Reynolds number of 3000-14000, Relative Roughness Height ( eh/D ) of height 0.030 to 0.035, Rib angle of attack 600, heat flux 720 W/m2 and pitch of relative roughness pitch 10 the Result has been compared with smooth duct under similar flow and boundary condition It is found from the investigation that on increasing the roughness of a roughened plate the friction factor andheat transfer performance of solar air heater increase and the rate of increase of heat transfer performance of solar air heater get reduced as the roughness of plate increases.Key words: Solar Air Heater, Duct, Absorber Plate, ArtificialRoughness, Reynolds Number Reference [1] Hsieh, J.S., Solar Energy Engineering, Printing Hall Inc.,New Jersey,1986.

"Minimization of Inventory & Transportation Cost Of an Industry"-A Supply Chain OptimizationAbstract: In this paper a study on three in-stock strategies – flow-through, regional and single DC central stock and developed a simple transportation-inventory model in order to compare their total costs is done. We have also described a distribution model proposed by in which the model is formulated as a non-linear integer optimization problem. Due to the non-linearity of the inventory cost in the objective function, two heuristics and an exact algorithm is proposed in order to solve the problem. The results obtained from the transportation-inventory models show that the single DC and regional central stock strategies are more cost-efficient respectively compared to the flow-through approach. It is recommended to take the single DC and the regional central stock strategies for slow moving and demanding products respectively: Minimizing inventory & transportation cost of an industry: a supply chain optimizationKey words: Supply chain, Preliminary Distribution model , Cross-Dock and Direct Shipment Models Lagrangian Method Reference [1] A.

20. | Development of a Composite Leaf Spring for a Light Commercial Vehicle (Tata Magic)
Development of a Composite Leaf Spring for a Light Commercial Vehicle (Tata Magic)Abstract: Present time the main issue of automobile industry are weight reduction. The automobile industry has looking for any implementation or modification to reduce the weight of the vehicle. The suspension leaf spring is one of the potential items for weight reduction in automobile as it accounts for 10% to 20% of the unsprung weight. The introduction of composite leaf spring made of glass fiber rein forced plastic (GFRP) has made it to possible to reduce the weight of spring without any reduction on load carrying capacity and stiffness. The achievement of weight reduction with adequate improvement of mechanical properties has made composite a very good replacement material for conventional steel spring. This work deals with the replacement of multi-leaf steel spring with mono composite leaf spring for the LCV. Suspension system in an automobile determines the riding comfort of passengers and the amount of damage to the vehicle. The main function of leaf spring assembly as suspension element is not only to support vertical load, but also to isolate road-induced vibrations. the behavior of leaf spring is complicated due to its clamping effects and inter-leaf contact etc. the objective of this paper is to replace the multi-leaf steel spring by mono composite leaf spring for the same load carrying capacity and stiffness. Since the composite materials have more elastic strain energy storage capacity and high strength-to-weight ratio as compared to those of steel. It is possible to reduce the weight of the leaf spring without any reduction on load carrying capacity and stiffness. The design constraints were limiting stresses and displacement. Modeling and analysis of both the steel and composite leaf springs have been done using ANSYS software.Key words: Composite Materials, Leaf Spring, Material Property, FEA, ANSYS, and Pro-E.

Effect of Burning By Fire Flame on Load Carrying Capacity of Self-Compacting Concrete ColumnsAbstract: This research presents experimentally investigated the effect of burning by fire flame on the behavior and load carrying capacity of reduced scale SCC column models. Residual ultimate load carrying capacity, load versus deflection curves, maximum crack width, axial deformation and crack pattern for column specimens with and without burning were recorded and discussed. The reinforced SCC columns were exposed to direct fire fame temperature levels of 752 and 1472oF (400 and 800oC) for 1.5 hour period of exposure at 60 days age. It was found that the predicted load carrying capacity of SCC columns by three codes (ACI-318/08, BS-8110/97 and Canadian/84), was unconservative after burning except the BS Code equation which was found able to predict load capacity after exposure to high fire temperature levels. Load-deflection curves indicate deleterious response to the fire exposure.Key words: Burning; Fire Flame; Load Carrying Capacity; SCC Columns Reference [1] Sakai, K., and Sheikh, S.

Detection of Fault Location in Transmission Lines using Wavelet TransformAbstract: This paper presents a technique to detect the location of the different faults on a transmission lines for quick and reliable operation of protection schemes. The simulation is developed in MATLAB to generate the fundamental component of the transient voltage and current simultaneously both in time and frequency domain. One cycle of waveform, covering pre-fault and post-fault information is abstracted for analysis. The discrete wavelet transform (DWT) is used for data preprocessing. It is applied for decomposition of fault transients, because of its ability to extract information from the transient signal, simultaneously both in time and frequency domain. MATLAB software is used to simulate different operating and fault conditions on high voltage transmission line, namely single phase to ground fault, line to line fault, double line to ground and three phase short circuit.Key words: Simulink, Transmission line Fault Detection, Wavelet, Discrete Wavelet Transform, Reference [1] A.H.Osman and O.P.Malik," Transmission line protection based on wavelet transform" ,IEEE Trans.

27. | Energy Saving Multipath Routing Protocol for Wireless Sensor Networks
Energy Saving Multipath Routing Protocol for Wireless Sensor NetworksAbstract: The Wireless sensor networks have many characteristics such as limited energy resources, low bandwidth and unreliable links. Due to these characteristics there are many challenges in the design of sensor networks. Routing in WSN is very challenging task. Multipath establishes several path for data transmission rather than single path. Due to this data delivery is high. In this paper, we propose energy saving multipath routing protocol (ESMRP). ESMRP make use of load balancing algorithm to transfer the data. ESMRP calculates node strength to discover its next best hop. Our protocol uses two versions, in the first version, data is transmitted through single path, if some path failure occurs or discovered path node strength goes below 15% of alternative path node strength then it will switch to next alternative path. In the second version of ESMRP, message is split into various segments and some correction codes are added to these segments. After that these segments are transmitted across multiple paths. Simulation results shows that the proposed protocol is more energy saving than previous protocol in providing efficient resource utilization.Key words: Correction codes, Energy Saving, Load Balancing, Multipath Routing, Wireless Sensor Networks Reference [1] T.

This research is inspired by simple appealing visualization of itemsets frequencies in the simple well known two dimension matrix representations. This paper proposes a new procedure to extract maximal frequent itemsets called Matrix Visualization and Extraction of Maximal Frequent Itemsets. The procedure consists of two steps. The first step sets the environment to mine data while the second extracts frequent itemsets. MVEMFI procedure has been tested by three synthetic datasets and processing time has been recorded. It has been found that MVEMFI performance is not affected by the number of transactions or the density of items' occurrences in the dataset.Key words: Association rules, Data mining, Maximal frequent itemset Reference [1] E.

34. | Impact of Condensate Recovery on Boiler Fuel Consumption in Textile Sector
Impact of Condensate Recovery on Boiler Fuel Consumption in Textile SectorAbstract: Energy is one of the main cost factors in the textile industry. Especially in times of high energy price volatility, improving energy-efficiency should be a primary concern for textile plants. There are various energy-efficiency improving opportunities that exist in every textile plant, many of which are cost-effective. Energy consciousness and environmental awareness have transformed condensate from an inexpensive byproduct of steam distribution to a valuable resource that can substantially reduce operating costs. The flash steam generated can contain up to half of the total energy of the condensate, hence flash steam recovery is also an essential part of an energy efficient system. This paper provides information on the steam consumption and recovery technologies and measures applicable to the textile industry. The paper includes case studies from various textile plants in sachin GIDC (Gujarat) and also provides the range of saving under varying conditions..Key words: Condensate recovery, Flash steam, Steam consumption, Textile industry Reference [1] Goyal Sandeep, "Energy Conservation in Textile industry, LAP Lambert Academic Publishing 2011 [2] Saad El-Din A.

35. | Wireless Sensor Network System to Monitor The Fish Farm
Wireless Sensor Network System to Monitor The Fish FarmAbstract: In recent years, the interest in Wireless Sensor Network (WSN) has been growing dramatically. To meet this trend, we have designed Wireless Sensor Network system to monitor the fish farm. We present a practical appli-cation of wireless network. The application requires two different kinds of modules; the sensor itself and the wireless module. The sensor collects and transmits the information to a wireless module using wired connection. Once the information reaches the wireless node, it is forwarded to the central unit through a wireless protocol. The sensor module includes a temperature sensor and pH sensor. The wireless node collects the sensed data by means of an asynchronic wired serial polling communication. The use of this kind of protocol allows connecting a single master with multiple slaves. In our particular case, we have connected one master with two slaves using a transmission rate of 9600 bits per second. The wireless transmission follows the standard IEEE 802.15.4 and implements the routing protocol based on the ZigBee standard.Key words: pH, Temperature, Wireless Sensor Network, ZigBee.

Content based web spam detection using naive bayes with different feature representation techniqueAbstract: Web Spam Detection is the processing to organize the search result according to specified criteria. Most often this refers to the automatic processing of search result, but the term also applies to the automatic classification of search results into ham and spam. Our work also evaluates change in performance by using different representation for the document vector like term frequency (TF), Binary, inverse document frequency (IDF) and TF-IDF. There are various Benchmark Datasets available for researchers related to web spam filtering. There has been significant effort to generate public benchmark datasets for anti- web spam filtering. One of the main concerns is how to protect the privacy of the users whose ham links are included in the datasets. We perform a statistical analysis of a large collection of WebPages, focusing on spam detection. Dimension reduction is important part of classification because it provides ease to visualize high dimensional data. This work reduce dimension of training data in 2D and full and mapped training and test data in to vector space.

Optimization of Process Parameters for Multi-Layer- Cum Microwave Drying Of Oyster Mushrooms (Pleurotus Sajor Caju)Abstract: Experiments on oyster mushroom were carried out to study the effect of multi layer-cum-microwave drying process parameters viz. loading density, air velocity and power level on the quality characteristics of the dried product. Quality characteristics viz. rehydration ratio, shrinkage ratio, texture, colour, overall acceptability of dried mushroom were analyzed. The process parameters were optimized using response surface methodology for responses with significant model and non significant lack of fit. The optimum operating conditions for air velocity, loading density and power level were 3.80 m/sec 38.80 kg/m2 and 413 W at 600C drying air temperature. Corresponding to these values of process variables, the value of rehydration ratio, shrinkage ratio, hardness, chewiness, colour change was 2.15, 0.84, 720 N, 473N and 15.50 respectively. The overall desirability was 0.78.Key words: Multi layer-cum-microwave drying, optimization, oyster mushroom, quality.

38. | Fast Data Collection in Multipath Routing With Independent Directed Acyclic Graphs
Fast Data Collection in Multipath Routing With Independent Directed Acyclic GraphsAbstract: in this paper, we introduce the concept of Independent Directed Acyclic Graphs (IDAGs) to achieve resilient multipath routing. The algorithm developed in this paper: (1) achieves multipath routing; (2) guarantees recovery from single link failure. The multipath routing scheme consists of an algorithm to determine a set of multiple disjoint or partially disjoint paths and a mechanism for distributing traffic over a multipath route to reduce the traffic load on a congested link. Multipath routing is capable of aggregating the resources of multiple paths and reducing the blocking capabilities in QoS oriented networks, allowing data transfer at higher rate when compared to single path. To improve the failure resiliency without jeopardizing the routing stability, we propose a local rerouting based approach called failure insensitive routing. Under this approach, upon a link failure, adjacent router suppresses global updating and instead initiates local rerouting. We demonstrate that the proposed approach provides higher service availability than the existing routing schemes.Reference [1] S. Cho, T. Elhourani,and S.

39. | Development of Self Repairable Concrete System
Development of Self Repairable Concrete SystemAbstract: During the serviceability of structure concrete is subjected to different damages. The common approach for repair of Structural concrete are: Polymer Injunction, External prestressing, Geomembranes and Polymer wraps. The above technique is based on addition of a repair material to concrete from outside to inside of structural members. Now we are going to develop the self-repairing concrete by adding the materials from inside the concrete to repair. Our technique to develop self-repairing concrete consists of embedding repairing materials in hollow ducts in the repairing zone before it is subjected to damage. Therefore when cracks occurs this repairs materials will get released from inside and it will enter the repairing zone. Where it will penetrate into cracks and rebound to mother material of Structure and it will repair the damage.Key words: Concrete – Serviceability – Cracks - Epoxy resins - Repairs Reference 1.

Performing DCT8x8 Computation on GPU Using NVIDIA CUDA TechnologyAbstract: In this paper, we have proposed sequential and parallel Discrete Cosine Transform (DCT) in compute unified device architecture (CUDA) libraries. The introduction of programmable pipeline in the graphics processing units (GPU) has enabled configurability. GPU which is available in every computer has a tremendous feat of highly parallel SIMD processing, but its capability is often under-utilized. The two-dimensional variation of the transform that operates on 8x8 blocks (DCT8x8) is widely used in image and video coding because it exhibits high signal de-correlation rates and can be easily implemented on the majority of contemporary computing architectures. Performing DCT8x8 computation on GPU using NVIDIA CUDA technology gives significant performance boost even compared to a modern CPU.Key words: Discrete Cosine Transform, Graphics Processor unit (GPU), Computed unified device architecture (CUDA).

41. | An Investigation On Performance Characteristics of Radial In-Flow Turbo-Expander with Backswept Curved Rotor
An Investigation On Performance Characteristics of Radial In-Flow Turbo-Expander with Backswept Curved RotorAbstract: In this research, results of the designed radial inflow turbo-expander with back swept curve blade rotor have been presented. The spiral casing is designed considering constant mean flow velocity and the areas of cross-sections of the spiral casing are decreased gradually by reducing the width of the flow areas from inlet to end. The rotor is shrouded to cope up with centrifugal as well as bending load on the vanes of the rotor and avoid energy losses due to the tip clearance. The degree of reaction is selected as 0.25 in contrast to usual value of 0.5 at design point on the consideration of absolute velocity of air at nozzle exit needs to be higher than the rotor tip speed. The rotor shaft assembly is supported by externally pressured air bearing. The turbine with coupled brake centrifugal compressor, aerostatic radial and thrust bearing and test rig are developed for conducting experiments. The experiments are conducted with compressed cold air by varying mass flow rates and pressure ratios. At the pressure ratio of 1.6 the temperature drop of 12.5oC of flowing air across turbo expander is achieved and 41% total to static efficiency is obtained. The findings of exhaustive experimentation with the developed turbo expander are illustrated in details in this paper.Key words: Air bearing, turbo expander, shrouded rotor, temperature drop Reference [1] Philip P.

Text Mining For Information Filtering Using PatternsAbstract: Many data mining techniques have been proposed with regard to mining valuable patterns with text docs. However, how you can effectively utilize and update discovered patterns is still an start research problem, especially from the domain regarding text mining. Since nearly all existing text message mining methods adopted term-based methods, they all experience the problems of polysemy and also synonymy. Over the years, people include often used the hypothesis that style (or phrase)-based methods should perform better than the term-based people, but a lot of experiments don't support this hypothesis. This project presents a progressive and effective pattern discovery technique which includes the techniques of style deploying and also pattern changing, to improve the potency of using and also updating observed patterns with regard to finding applicable and fascinating information.Key words: Classification, Granule mining, Pattern Mining, Text Mining, Reference [1] M.

Robotic surgery can accomplish what doctors cannot because of precision and repeatability of robotic systems. Besides, robots are able to operate in a contained space inside the human body. All these make robots especially suitable for non-invasive or minimally invasive surgery and for better outcomes of surgery. Today, robots have been demonstrated or routinely used for heart, brain, and spinal cord, throat, and knee surgeries at many hospitals in the United States (International Journal of Emerging Medical Technologies, 2005).Key words: Bearings, Robot Machinery, Sensors, Synthetic molecular motors, Telesurgery techniques Reference [1] "Telepresence surger'', SRI Center for Medical Technology "Medical Robotics'', Lara Crawford, Robotics Lab, University of Berkeley, California [2] "An experimental telesurgery robot", G.C.

45. | Embedded Multi-Resolution Signal Tracing For Amba Ahb With Real Time Lossless Compression
Embedded Multi-Resolution Signal Tracing For Amba Ahb With Real Time Lossless CompressionAbstract: AHB Bus Tracer is a significant infrastructure that is needed to monitor the on chip-bus signals, which is vital for debugging and performance analysis and also optimizing the SOC. Basically on chip signals are difficult to observe since they are deeply embedded in a SoC and no sufficient I/O pins are required to access those signals. Therefore, we embed a bus tracer in SoC to capture the bus signals and store them. In this paper a multiresolution AHB On-Chip bus tracer is proposed for system-on-chip (SoC) debugging and monitoring which is capable of capturing the bus trace with different resolutions and efficient built-in compression mechanisms. Subsequently compression of the trace without any loss of the actual trace which when reconstructed at the analyzer will remain the same. The trace data will be decompressed on the host for further observation and debugging. The experimental results show that the proposed approach was designed successfully; the RTL simulations were performed successfully along with successful synthesis using Xilinx ISE.Key words: AMBA, AHB Bus Tracer, Real Time Compression, multi-resolution, signal tracing.

Study Of Height Dependency Of Drape ParametersAbstract: Drape coefficient is a dependent value which itself is not sufficient to describe drape. Along, with this other drape parameters are also required to have a profound understanding of drape. In this paper it has been tried to find out the height dependency of these parameters to explain drape more explicitly. It shows that a positive correlation exists between the height of hanging and drape coefficient, Nodal length whereas a negative correlation exists with drape distance ratio. Poor correlation is seen with other parameters. These outcomes can be used to improve garment designing applications.Key words: Drape, Drape coefficient, Height of Hanging, Node parameters, Drape parameters Reference [1] Mailis Mäkinen and Harriet Meinander, "Influence of Physical Parameters on abric Hand",Tampere University of Technology, SmartWearLab, Christiane Luible and Nadia Magnenat-Thalmann University of Geneva, MIRALab.

48. | Design and Implementation of Robust Router Using Vlsi
Design and Implementation of Robust Router Using VlsiAbstract: In his paper we attempt to give a networking solution by applying VLSI architecture techniques to router design for networking systems to provide intelligent control over the network. Networking routers today have limited input/output configurations, which we attempt to overcome by adopting bridging loops to reduce the latency and security concerns. Other techniques we explore include the use of multiple protocols. We attempt to overcome the security and latency issues with protocol switching technique embedded in the router engine itself. The approach is based on hardware coding to reduce the impact of latency issues as the hardware itself is designed according to the need. We attempt to provide a multipurpose networking router by means of Verilog code, thus we can maintain the same switching speed with more security as we embed the packet storage buffer on chip and generate the code as a self-independent VLSI Based router. Our main focus is the implementation of hardware IP router. The approach enables the router to process multiple incoming IP packets with different versions of protocols simultaneously, e.g. for IPv4 and IPv6. The approach will results in increased switching speed of routing per packet for both current trend protocols, which we believe would result in considerable enhancement in networking systems.Key words: Robust Router, packets, FPGA, RTL, IP Reference [1] Y.

50. | Base Rock Vibration Characteristics Analysis from Surface Ground Motion
Base Rock Vibration Characteristics Analysis from Surface Ground MotionAbstract: A computer program is developed assuming underlying soil as horizontally layered and one-dimensional. Soil material non-linearity is considered in this problem. One dimensional shear wave equation is solved. Space is discretized by Finite Element method and time is discretized by Central Difference method. Two parameter hyperbolic model and Masing rule are used to obtain the dynamic stress-strain behaviour. The number of soil layers, the properties of different soil layers such as density, initial shear modulus, reference strain and the properties of rigid base rock such as density and shear modulus are used as input data. Record of the earthquake which occurred at El-Centro in 1940, is used here as surface acceleration data. The output of the program is dynamic stress-strain behaviour in different soil layers, variation of secant shear modulus with time in different soil layers, deformation in different soil layers and base rock acceleration of the soil layer. The soil properties data assumed here is soft layer in the upper portion and comparatively stiffer layer in the bottom layer. The base rock layer is the stiffest layer. The peak base rock acceleration is found greater than the peak surface acceleration. Hysteresis loop is maintained in each layer of the soil column for obtaining dynamic stress-strain behaviour. Variation of secant shear modulus with time is fluctuating. The surface deformation is found greater than the base rock deformation.Key words: Central Difference method, Finite Element Method, Hyperbolic Model, Secant Shear Modulus, Hysteresis Loop.

55. | Stability Analysis of Controlled Two Area System Using Fgpi Controller
Stability Analysis of Controlled Two Area System Using Fgpi ControllerAbstract: The dynamic behavior of power system depends up on disturbances and on changes in the operating point. In interconnected large power systems, variations in frequency can lead to serious large scale stability problems. Load characteristics, unexpected changes in power demand and faults also affect the stability. Load frequency control (LFC) is one of the major requirements in providing reliable and quality operation in multi-area power system. Conventional PID control schemes will not reach a high performance. A gain scheduling controller can be used for nonlinear systems. Some fuzzy gain scheduling of PI controllers have been proposed to solve such problems in power systems and who developed different fuzzy rules for the proportional and integral gains separately.Index Terms: LFC, ACE, FGPI etc., Reference [1] E.

Performance Analysis of Modified CHB Multilevel Inverter using Various Carrier Modulation SchemesAbstract: This paper describes various Carrier Modulation PWM scheme and its performance analysis for nine-level Modified Cascaded H-Bridge Multilevel Inverter (M-CHB-MLI). This M-CHB-MLI topology with a multi conversion cell consists of four equal voltage sources with four controlled switches and four diodes. Instead of 16-controlled switches used in conventional topology for 9-level output voltage, only eight controlled switches are required for 9-level M-CHB-MLI topology which in turn reduces the switches losses and also improves its performance parameters. The various carrier modulation schemes are applied for this M-CHB-MLI to analyze its output voltage harmonics and Vrms.Key words: Carrier Overlapping Phase Disposition PWM (CO-PD PWM), Carrier Overlapping Phase Opposition Disposition PWM (CO-POD PWM), Carrier Overlapping Alternate Phase Opposition Disposition PWM (CO-APOD PWM), Variable Carrier Frequency PWM (VCF PWM), Modified Cascaded H-Bridge Multilevel Inverter (M-CHB-MLI), Multicarrier sinusoidal PWM.

57. | Energy-Efficient Power Allocation And Performance Estimation For MIMO-MRC Systems
Energy-Efficient Power Allocation And Performance Estimation For MIMO-MRC SystemsAbstract: Adaptive power allocation problem where it minimizes the energy-per-good bit (EPG) of a system employing a multiple-input multiple-output maximum ratio combining (MIMO-MRC) scheme is formulated. Closed-form results are obtained for the optimum transmit power and minimum EPG as a function of the number of antennas employed and the quality of the channel. The cumulative distribution function (CDF) of the minimum EPG in closed form is obtained to assess the performance of the solution in a statistically varying channel. The energy-efficiency trade-off between enhanced diversity and the increased circuit power consumption of multiple antennas is explored. In particular, EPG CDF in a numerical example is used to find the most energy-efficient number of antennas for a given probability of outage. Both Rayleigh and Rician MIMO fading channels are considered.Key words: Energy minimization, MIMO, beamforming, MIMO MRC, fading channels, adaptive power allocation. Reference [1]. G. Caire, G.

60. | An Efficient Security Mechanism for Data Reporting In Wireless Sensor Networks
An Efficient Security Mechanism for Data Reporting In Wireless Sensor NetworksAbstract: Wireless sensor networks consist of a large number of small sensor nodes having limited computation capacity, restricted memory space, limited power resource, and short-range radio communication device. In these scenarios, sensor networks may suffer different types of malicious attacks. The adversaries can inject false data reports via compromised nodes and launch DoS attacks against legitimate reports. Recently, a number of filtering schema for removing false data report .But due to lack of strong filtering capacity and not support dynamic sensor networks The main objective of this application is to propose a dynamic en-route filtering scheme that addresses both false report injection and DoS attacks in wireless sensor networks. In our scheme, each node has a hash chain of authentication keys used to endorse reports; meanwhile, a legitimate report should be authenticated by a certain number of nodes. First, each node release its key to forwarding nodes. Then, after sending reports, the sending nodes disclose their keys, allowing the forwarding nodes to verify their reports. The Hill Climbing key release approach is used in this approach which ensures the nodes closer to data sources have stronger filtering capacity The DoS attacks can be solved with multipath routing to deal with the topology changes of sensor networks. The proposed filtering scheme can drop false reports earlier with a lower memory requirement, especially in highly dynamic sensor networks.Key words: Data reporting, en-route filtering scheme, wireless sensor networks Reference [1] N.

Enhancement of Information Retrieval in Distributed SystemsAbstract: The distributed system enables multiple, simultaneous connections between clients and Inquery servers. The different components of the system communicate using a local area network. Each component may reside on a different host and operates independently of the others. In this section, we describe the functionality and interaction between the clients, the connection server, and the Inquery servers. The clients are lightweight processes that provide a user interface to the retrieval system. Clients interact with the distributed IR system by connecting to the connection server. The clients initiate all work in the system, but they perform very little computation. The clients can issue the entire range of IR commands but, in this paper, we focus on inquery, document retrieval commands and query evaluation measurements. A client sends query commands to the connection server.Key words: Simulation model, Query retrieval measurements, Document retrieval measurements, Distributed retrieval. Reference [1].

A lot of work has been done in languages like Chinese, Arabic, Devnagari, Urdu and English. A neural network based Gurmukhi recognition system has been developed. Range free skew detection and correction algorithms for de-skewing Gurmukhi machine printed text skewed at any angle have been developed. If different classifiers cooperate with each other group decisions may reduce errors drastically and achieve a higher performance. The whole process consists of two stages. The first, feature extraction stage analyzes the set of isolated characters and selects a set of features that can be used to uniquely identify characters. The performance depends heavily on what features are being used. Main advantage of this system is its accuracy to extract the Punjabi word. Input to the system is the scanned images from newspaper, magazines and old books and Extract the Punjabi Word from Machine printed Document Images.Key words: OCR, Extraction, Punjabi Word, Machine Printed, Gurmukhi, Segmentation, Pre-Processing, Skeletonization, Noise Removal, HGCR, MATLAB Reference [1] J.

66. | User Specific Word Based Image Search from Photo Sharing Websites
User Specific Word Based Image Search from Photo Sharing WebsitesAbstract: Increasingly developed social sharing websites, like Flickr and Youtube, allow users to create, share, annotate and comment medias. The large-scale user-generated meta-data not only facilitate users in sharing and organizing multimedia content, but provide useful information to improve media retrieval and management. Personalized search serves as one of such examples where the web search experience is improved by generating the returned list according to the modified user search intents. In this paper, we exploit the social annotations and propose a novel framework simultaneously considering the user and query relevance to learn to personalized image search. The basic premise is to embed the user preference and query-related search intent into user-specific topic spaces. Since the users' original annotation is too sparse for topic modeling, we need to enrich users' annotation pool before user-specific topic spaces construction. The proposed framework contains two components: 1) A Ranking based Multi-correlation Tensor Factorization model is proposed to perform annotation prediction, which is considered as users' potential annotations for the images; 2) We introduce User-specific Topic Modeling to map the query relevance and user preference into the same user-specific topic space. For performance evaluation, two resources involved with users' social activities are employed. Experiments on a large-scale Flickr dataset demonstrate the effectiveness of the proposed method.Index Terms: personalized image search, tensor factorization, topic model, social annotation.

69. | FABRICATION AND TESTING OF ULTRASONICALLY ASSISTED STIR CAST AA 5083-Sicp COMPOSITES
FABRICATION AND TESTING OF ULTRASONICALLY ASSISTED STIR CAST AA 5083-Sicp COMPOSITESAbstract: Aluminum Matrix composites (AMCs) are light weight, high-strength materials with potential application in areas such as automobile, aerospace, defence, engineering and other industries. AMCs are projected to significantly reduce the overall weight of the vehicles and aircraft while maintaining satisfactory structural strength. Reinforcement of micron or nano-sized range particles with aluminium matrix yields improved mechanical and physical properties in composite materials. The distribution of nano sized reinforcing particles also changes morphology and interfacial characteristics of nanocomposites. In this study, AA 5083 alloy micron and nano SiC composites have been fabricated by Ultrasonic assisted stir casting. Different weight % of SiC particles Micron (3, 5, 8, and 10 wt%) and Nano (1, 2, 3 and 4 wt%) were used for synthesis of composites. SEM microstructure shows uniform distribution of SiC particles with agglomeration at some places. Various properties of composites like tensile strength, compressive strength, hardness, ductility, density were measured. Results revealed that the tensile strength, compressive strength and hardness of composites increases with increase the weight % of SiC particles and particle size reduction. However ductility of composites with micron SiC particles reduced in large value with increasing the weight % of SiC however with addition of nano SiC particles only a small reduction in ductility was observed. The application of ultrasonic vibration on the composite during melting not only refined the grain structure of the matrix, but also improved the distribution of nano-sized reinforcement.Key words: Aluminum Matrix Composites, Ultrasonic Assisted Casting, Agglomeration, Nanocomposites Reference [1] Rupa Dasgupta, Humaira Meenai, "SiC particulate dispersed composites of an Al–Zn–Mg–Cu alloy: Property comparison with parent alloy", Materials Characterization, 54, 2005, 438-445.

70. | Introduction To Turbochargers For Modern Diesel Engines
Introduction To Turbochargers For Modern Diesel EnginesAbstract: CO2 emissions reduction for vehicles and demand for more driving comfort are the challenges for the automobile industry today. One approach to this problem is the reduction of the displacement of combustion engine while maintaining the characteristics of large displacement engine. This method is often referred to using the term" downsizing" and requires the engine to be turbocharged to improve its performance and torque. It has been demonstrated that a simple charging unit alone is not enough and more complex charging systems are required when emission norms are stringent. The goals of a developed engine in terms of the thermodynamics and operation of future passenger car are increase in the power density of the engine, highest possible maximum torque at low engine speeds across the widest possible range of speeds, improvement of the driving response in transient operating conditions like start up response and elasticity response, reduction of the primary energy consumption during testing and driving on the road, observances of the future exhaust gas thresholds which mean a drastic reduction in the current emission levels. The latter goals can be reached through the use of smaller displacement engines. Engines with low engine displacement yield significant advantages in the test cycles with respect to fuel consumption and emissions, but the torque produced by small engine is pronouncedly less than that of a large displacement, naturally aspirated engine attained in terms of the steady state response and of the transient response.

A Comparative Study on Design and Operation of Fluorescent Lamps, Cfls and LedsAbstract: Compact Fluorescent Lights (CFLS) and Light Emitting Diodes (LEDs) have risen to a great popularity in recent years due to outstanding features such as longevity and energy-efficient design. These bright, compact lights are usually designed to reduce the energy consumption without sacrificing light or productivity. In fact, manufacturers are now producing CFLs that are designed to fit into our exiting light fixtures which eases the transition from traditional incandescent bulbs to more energy-efficient alternatives.Fluoroscent Lamps practically emerged in 1934.During the past 80 years this lamp has undergone numerous changes in materials and design to ensure a leading position as the lamp offering the lowest total cost of ownership while producing a high quality white light. This paper presents the design, working, operation,advantages and future use of the above technologies. It also compares the LED system with other technologies(CFLand Fluoroscent lamps).Key words: Ballast,CFLs,LEDs,Fluorescent,Lumen Reference [1]. Agrawal, D. C. & Menon, V. J. (1998).

Speech Recognition for Robotic ControlAbstract: The main goal of this paper is to introduce "hearing sensor" and also the speech synthesis to the Mobile robot such that it is capable to interact with human through spoken natural language. The context of speech recognition refers to system where a person can speak via a microphone to a computer. The computer translates the spoken words into either text or commands to execute functions in the computer. The intelligent speech recognition system enables the robot to understand spoken instructions. The speech recognition system is trained in such a way that it recognizes defined commands and the designed robot will navigate based on the instruction through the speech commands. The complete system consists of three subsystems: the speech recognition system, a central controller, and the robot. The results prove that the proposed robot is capable of understanding the meaning of speech commands. They will act autonomously in a natural environment and will communicate in a natural way with those people they are supposed to support.Key words: human robot interface, robot, speech recognition, Reference [1] P.

73. | Characterization of New Cast Iron Alloys for the Stub-Anode Connection in the Aluminium Reduction Cells
Characterization of New Cast Iron Alloys for the Stub-Anode Connection in the Aluminium Reduction CellsAbstract: High phosphorus gray iron (HPGI) is used to connect the steel stub of an anode rod to a prebaked anode carbon block in the aluminium reduction cells. The electrical resistance and resistivity properties, for different grades of cast iron, were tested and measured at different temperatures - using bench scale set ups- and evaluated as a potential replacement for the existing HPGI due to the limitations of that material. These cast iron alloys include low-phosphorus gray iron, ductile irons with compositions typical for ferritic (FDI), pearlitic (PDI) ductile iron grades and three alloys with low phosphorous irons with different carbon equivalents. The thermal expansion for steel stub, HPGI, and for the succeeded cast iron alloy was measured using high precision automatic dilatometer and analyzed. Microstructures and mechanical properties of the selected alloy were tested and compared with the existing HPGI. The results shown that, the contact pressure, at steel stub-cast iron collar-anode connection, plays the major role in determining the electrical resistance and hence the voltage drop. Gray iron with carbon equivalent=4.5 has the lowest electrical resistivities compared with the other tested cast iron alloys, meanwhile carbides in the as-cast structures seem to be beneficial in increasing the thermal expansion and hence the contact pressure during the anode service life. The saving percent in voltage drop between gray iron with carbon equivalent =4.5 and HPGI reached to 18%.Key words: Different cast iron alloys, microstructure, electrical resistivity and resistance, thermal expansion and mechanical testing Reference [1] S.

74. | Thermal Stress Analysis of Beam Subjected To Fire
Thermal Stress Analysis of Beam Subjected To FireAbstract: The effect of thermal stresses and deformations on the performance of structure due to increase in temperature is generally not treated in design codes and standards. This project describes the behaviour of structure when subjected to high temperature. The change in temperature makes material to expand and if this expansion is restrained, stresses are induced which affect expected performance of structure. The force generated by restrains is very large and its ignorance can lead to unsafe design. When structure is subjected to high temperature, it results in reduction in stiffness and strength which significantly affects the structural performance. In this paper analysis of beam subjected to fire loading is done. Response of steel beam subjected to ISO 834 fire with different types of restraining support condition is studied.Key words: fire load, heat transfer, ISO 834, thermal analysis, thermal properties.

76. | Impact of Cold and Hot Exhaust Gas Recirculation on Diesel Engine
Impact of Cold and Hot Exhaust Gas Recirculation on Diesel EngineAbstract: Today most of the transport vehicles in countries like India where cost effective is the predominant criteria utilize diesel engines rather than petrol engines. From past 5 years usage of diesel engines was rapid which can be addressed from the sales report of many automobile companies. The reason behind this could be cost of diesel fuel and efficiency of the diesel engine when compared to petrol engine. But when we look on the worse side of diesel engine, emissions from diesel engine are high especially NOx. So there is a need for a technique which could reduce the emissions without affecting the performance of engine. One such technique could be Exhaust gas recirculation. Present paper aims to find the impact of cold and hot EGR on emissions of diesel engine.Key words: Effective, Efficiency, Emissions , NOX Reference [1] Ming Zheng a, Graham T. Reader b, J.

79. | Characterization and Corrosion Study of Titanium Anodized Film Developed in KOH Bath
Characterization and Corrosion Study of Titanium Anodized Film Developed in KOH BathAbstract: Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts. Aluminum is ideally suited to anodizing, although other nonferrous metals, such as tantalum and titanium, can also be anodized. Titanium is used as a biocompatible material in human implants due to its excellent corrosion and wears resistance. Stable, continuous, highly adherent, and protective oxide films can be developed on titanium using various acid or alkaline baths. Anodizing of titanium generates a spectrum of different color without use of dyes. This spectrum of color dependent on the thickness of the oxide, interference of light reflecting off the oxide surface and reflecting off the underlying metal surface. The anodized film of Titanium is mainly consists of TiO2 or mixtures of TiO2 & Ti2O3 etc. In the present work, Pure Titanium plate has been anodized using bath of KOH at different voltage ranges. The anodized film is characterized by visual observation, SEM & EDAX analysis & A.C impedance spectroscopy, while the corrosion studies were performed using salt spray test & potentiodynamic studies. Result of various studies shows that Anodized film was mainly consisting of TiO2 and Ti2O3, having spectrum of colors from Blue-Yellow-Purple-Green. The film is more compact, adherent and more uniform due to which it exhibits good corrosion resistance.Key words: Anodizing of Titanium, Coloring Effect, Potentiodynamic Test, AC Impedance Test, Salt Spray Test, and SEM & EDAX analysis Reference [1] A.

Discriminative Feature Based Algorithm for Detecting And Classifying Frames In Image SequencesAbstract: This method is used to detect and classify frames in different videos. By detecting frames similar video as input video and related videos are retrieved. Content Based Copy Detection method used to find content related frames from multiple shots. To improve the efficiency of Content Based Copy Detection the videos are cropped that means removing the black bars from horizontal and vertical position. These cropped videos are robust to cam cording and encoded video. Affinity Propagation and exemplar based clustering used to reduce the number of frames in each video. In Exemplar based clustering unique frames are selected from multiple shots and Affinity Propagation used to cluster the unique frames. So it will be useful in detect the frames and compare the input video with all frames. Affinity Propagation uses different similarity metrics to detect the difference between two frames or two videos. Frame classification results are achieved by tiny videos when compared with the tiny images framework. Therefore video frames convert into low dimensional resentation that means resize the frames Frames into 32*32 pixels and concatenating the color channels to reduce the sensitivity in variation. Simple data mining technique that is nearest neighbor method to perform related video retrieval and frame classification. This method can be effectively used for recognizing research that is video as same as to input video will be retrieved and related videos also retrieved.Reference [1] Aarabi.P and Karpenko.A , (2008 ) 'Tiny Videos: Non-Parametric Content-Based Video Retrieval and Recognition,' Proc.

81. | Text Categorization Using First Appearance And Distribution Of Words
Text Categorization Using First Appearance And Distribution Of WordsAbstract: Text categorization is the task of assigning predefined categories to natural language text. Previous researches usually assign a word with values that express whether this word appears in the document concerned or how frequently this word appears. These features are not enough for fully capturing the information contained in a document. This project extends a preliminary research that advocates using distributional features of a word in text categorization. The distributional features encode a word's distribution from some aspects. In detail, the compactness of the appearances of a word and the position of the first appearance of a word are used. The proposed distributional features are exploited by a tfidf style equation, and different features are combined using ensemble learning techniques. The distributional features are especially useful when documents are long and the writing style is casual.Reference [1] L. D. Baker and A.K.

82. | A Novel Technique For Simulation & Analysis Of SVPWM Two &Three Level Inverters
A Novel Technique For Simulation & Analysis Of SVPWM Two &Three Level InvertersAbstract: This paper proposes a software implementation for two level & three level inverter using space vector modulation techniques. This software implementation is performed by using MATLAB/SIMULINK software. This paper gives comparison between SVPWM Three phase two level & three level inverter. Two level inverter is the basic technique to implement any level. The main advantage of the two level inverter is simple in computation and also switching device selection is simple. It is becomes difficult in high voltage & high power applications due to the increased switching losses and limited rating of the dc link voltage. Multilevel inverters are used in high voltage and high power applications with less harmonic contents. The harmonic contents of a three level inverter are less than that of two level inverters. And also rating of the dc link voltage is high. The simulation study reveals that three level inverter generates less THD compared to two-level inverter.Key words: SVPWM, THD, TWO LVEL &THREE LEVEL INVERTERS Reference [1] D.Rathnakumar and LakshmanaPerumal, and T.Srinivasan, "A New software Implementation of Space vector PWM," 0-7803-8865-8/05/$20.00 ©2005 IEEE.

Design and Analysis of Quality Control in Process Industries Using LabviewAbstract: In all process Industries, to get quality product as output, the ingredients have to be composed in correct composition. So, to control quality of output product, we have to control the quantity of ingredients to be composed. In this paper, we have designed virtual Instrument which controls the process assessing the percentages of ingredients of any product using Lab VIEW. It checks whether added sum of percentages is equal to 100% or else halts the process. There by, it prevents the unequal percentage composition of ingredients to be composed. In spite of having many more techniques to make quality analysis followed by quantity analysis, Lab VIEW is most preferred among them. This paper provides the facility to evaluate a chemical composition before it is to be composed.Key words: Composition, Ingredients, Lab View, Quality Analysis Reference [1] The handbook of Virtual Instrumentation using Lab VIEW [2] The handbook of PC- based Instrumentation by N.Mathivanan [3] Lab VIEW Tutorial Mannual,Jan 1996 Edition [4] Gary Johnson, Lab VIEW Graphical Programming, 2nd edition, McGraw Hill, Newyork, 1997 [5] Lisa K. wells & Jeffrey Travis, Lab VIEW for everyone, Prentice Hall, New Jersey, 1997 V.

86. | Casting Selfish Nodes Into Non Selfish In Replica Allocation Over Mobile Ad Hoc Network
Casting Selfish Nodes Into Non Selfish In Replica Allocation Over Mobile Ad Hoc NetworkAbstract: The nodes in Mobile Ad Hoc Network are resource constrained. This drawback and mobility nature of nodes can cause network partitioning and degradation of performance. Traditionally replica allocation techniques were used to overcome the drawback of performance degradation. It is assumed that all nodes in MANET share their memory resources fully. However, in reality the nodes may behave selfishly instead of cooperating in communication process. The selfishness exhibited by some of the nodes may lead to reduced quality of data accessibility over network. Recently Choi et al. studied the impact of selfish nodes from replication allocation perspective. Their solution is named "Selfish Replica Allocation". They proposed a novel replica allocation and selfish node detection. In this paper we implemented those mechanisms for casting selfish nodes in non selfish from the perspective of replica allocation. We built a custom Java simulator to demonstrate the proof of concept. The empirical results reveal that the approach shows higher performance when compared with existing techniques in terms of communication cost, data accessibility and average query delay.Index Terms: Mobile ad hoc networks, selfish node, selfish replica allocation Reference [1] T.

87. | Eco-Friendly Electricity Generator Using Scintillating Piezo
Eco-Friendly Electricity Generator Using Scintillating PiezoAbstract: The concept is to capture the normally lost energy surrounding a system and converting it into electrical energy that can be used to extend the lifetime of that system's power supply or possibly provide an endless supply of energy to an electronic device which has led to power harvesting. One of the most interesting methods of obtaining the energy surrounding a system is to use piezoelectric materials. There exists variety of energy harvesting techniques but mechanical energy harvesting happens to be the most prominent. This technique utilizes piezoelectric components where deformations produced by different means are directly converted to electrical charge via piezoelectric effect. Subsequently the electrical energy can be regulated or stored for further use. The proposed work in this research recommends Piezoelectricity as a alternate energy source. The motive is to obtain a pollution-free energy source and to utilize and optimize the energy being wasted. In this paper important techniques are stressed upon to harness the energy generated from piezo crystals. Piezoelectric materials have a crystalline structure that provides a unique ability to convert an applied mechanical strain into an electrical potential or vice versa. These two properties allow the material to function as a power harvesting medium. In most cases the piezoelectric material is strained through the ambient vibration around the structure, thus allowing a frequently unused energy source to be utilized for the purpose of powering small electronic systems.Key words: Piezoelectric materials, Electrical energy, Piezoelectricity, Mechanical strain, Electrical potential, Pollution-free energy, Crystalline structure Reference [1] Ramakant A.

Reservation Based Vehicle Parking System Using GSM and RFID TechnologyAbstract: This paper is to develop a Reservation based vehicle parking reservation system to overcome the problem of unnecessary time consumption in finding parking spot in commercial parking areas. In this proposed system, we reserve the parking slot in shopping malls, theatres and offices by using short message service (SMS). User reserves the slot by sending a message to GSM modem placed at the parking end. GSM modem gives slot number and a password if the slots are available which is used to allow or deny access to the parking area at the entrance and exit. IR sensor is used for the indication of empty slot with a green LED. User can park the vehicle at the given zone, and this is valid up to a certain grace period only after that the priority will be given to next user. RFID technology is used for entering and exiting parking area and also used to debit the amount for parking charges through RFID tag. The main contribution is the system has more security .Thus users can just reserve the parking slots using the SMS.Key words: GSM, RFID, IR sensor, SMS Reference [1].

Comparative Analysis of Mobile Security Threats And SolutionAbstract: Presently, 96% of smartphones do not have pre-installed security software. This lack in security is an opportunity for malicious cyber attackers to hack into the various devices that are popular i.e. Android, iPhone and Blackberry. Traditional security software found in personal computers (PCs), such as firewalls, antivirus, and encryption, is not currently available in smartphones. Smartphones are small and are easy to carry anywhere. Unfortunately, the convenience of using smartphones to do personal task is the loophole cyber attackers need to gain access to personal data. In this paper, we have tried to identify threats and deal with the subject of security in four fields. These four areas include: Security of mobile device, security of operating system on mobile device, security of mobile database and security of mobile network.

94. | An ANN Based Speed Control of PMBLDCM Drive Using a Single-Stage PFC Half-Bridge Converter
An ANN Based Speed Control of PMBLDCM Drive Using a Single-Stage PFC Half-Bridge ConverterAbstract: In this paper, a buck half-bridge DC-DC converter is used as a single-stage power factor correction (PFC) converter for feeding a voltage source inverter (VSI) based permanent magnet brushless DC motor (PMBLDCM) drive. The front end of this PFC converter is a diode bridge rectifier (DBR) fed from single-phase AC mains. The PMBLDCM is used to drive a compressor load of an air conditioner through a three-phase VSI fed from a controlled DC link voltage. The speed of the compressor is controlled to achieve energy conservation using Back Propagation network Algorithm Where DC link voltage is controlled proportional to the desired speed of the PMBLDCM. Therefore the VSI is operated only as an electronic commutator of the PMBLDCM. The stator current of the PMBLDCM during step change of reference speed is controlled by a rate limiter for the reference voltage at DC link. The proposed PMBLDCM drive with voltage control based PFC converter is designed, modeled and its performance is simulated in Matlab-Simulink environment for an air conditioner compressor driven through a 1.5 kW, 1500 rpm PMBLDC motor. The evaluation results of the proposed speed control scheme with Back propagation agorithm a concept of ANN (Artificial neural network)are presented to demonstrate an improved efficiency of the proposed drive system with PFC feature in wide range of the speed and an input AC voltage.Key words: PFC, PMBLDCM, Air conditioner, Buck Half bridge converter, Voltage control, VSI Reference [1] T.

95. | A Simulation of Effects of Compression Ratios on the Combustion in Engines Fueled With Biogas with Variable CO2 Concentrations
A Simulation of Effects of Compression Ratios on the Combustion in Engines Fueled With Biogas with Variable CO2 ConcentrationsAbstract: The structure of conventional engines is maintained while they are converted to biogas- powered engines so that they can reuse petroleum as fuel when needed as before conversion. In this case the detonation problem should be treated. This paper simulates the effects of compression ratio on the combustion in the engines fueled with biogas containing different CO2 concentrations. The results show that the compression ratio strongly influences the pressures at the end of combustion processes, but it presents some effect on the final combustion temperatures and on heat release curves. With a given compression ratio of 12, the temperatures and pressures at the end of combustion in engines decrease by 473K and 2 MPa respectively; while, the molar concentration of CO2 in the fuel increases from 20% to 40%.Key words: Biogas, Combustion, Compression ratio, Engine, Simulation.

97. | Zigbee Network for Biomedical Signal Monitoring: Preliminary Results
Zigbee Network for Biomedical Signal Monitoring: Preliminary ResultsAbstract: Wireless medical devices have been widely used inside hospitals, medical centers, ambulances and patients home. The wireless connectivity enable remote monitoring of patients' vital signs and improved care providers' ability to deliver timely treatment, leading to a better health care system. ZigBee is one of the technologies which have been widely used for wireless monitoring bioelectrical signals from patient freely moving. The objective of this work is to develop a wireless monitoring system for acquiring, monitoring and processing blood oxygenation, heart rate and body temperature. It is also presented a graphical interface for controlling and managing the ZigBee network devices. The ZigBee network was implemented by using the MC13213-EVK kit from Freescale Semiconductor and data were measured by the MED-SPO2 development kit. Additionally, the body temperature circuit was developed by using a negative temperature coefficient resistor. Data were recorded from 3 healthy volunteers of 25, 28 and 65 years old and recorded to a host computer. Comparisons were made by using commercial standard devices. The maximum error was found to be approximately 3.2% for the heart rate whereas a maximum of 1% for the others measured data. The network communication link between the sensors and the host computer was approximately 13 meters inside a room with walls but without using router devices. It can be concluded that the use of a wireless ZigBee system for monitoring and transmitting bioelectrical signals is feasible and it can be adjusted according to the patient needs. This might give to patient greater mobility for their daily activities during the day and it may also assist hospitals and medical centers with a great tool for monitoring and post-processing patients' vital signs.Key words: Biomedical Sensors, Signal Acquisition, Wireless Network, ZigBee.

Human Emotion Recognition by Using Pattern Recognition NetworkAbstract: Identifying Human Emotion is important in facilitating communication and interactions between individuals. They are also used as an important mean in studying behavioral Science and in studying Psychological changes. Since face is the prime source for recognizing human emotion, the proposed system will provide a quick and practical approach for non-invasive emotion detection. The recognition of emotions is done by deploying an intelligent system using neural network, signal processing and image processing toolbox of Matlab 7.12.0(R2011a). The network classifier is pattern recognition network which is actually a feed forward neural network that will be trained for some images bearing different emotions. The trained network is then simulated to test the new data for recognizing different emotions.Key words: Discrete Cosine Transform, Pattern Recognition Network Reference [1].

Peak-To-Average Power Ratio (PAPR) Reduction in Ofdm Systems Using Dummy Signal Hybrid Slm-Pts TechniqueAbstract: OFDM is a promising technique for the present generation communication systems where high data rate and fading channels are of major concern. However still some challenging issues remain unresolved in the design of OFDM systems. One of the major problem is high PAPR. The high PAPR of transmitted systems reduces the system efficiency and hence increases the cost of Radio Frequency(RF) Power Amplifier and also degrades the BER. In this paper, a Dummy Signal Hybrid (DH) SLM-PTS scheme is proposed to obtain the better PAPR reduction performance with reduced computational complexity. The simulation results are examined with other hybrid schemes and found that DH scheme provides better PAPR reduction performance compared to other hybrid schemes but at the cost of computational speed, because each time it compares the PAPR of the signal with threshold value and generates dummy signal accordingly with reduced PAPR.Key words: CCDF, OFDM, PAPR, PTS, SLM.

103. | A Novel Approach for Controlling Mobile Data Offloading Between 3GPP and Non-3GPP Access Networks.
A Novel Approach for Controlling Mobile Data Offloading Between 3GPP and Non-3GPP Access Networks.Abstract: Mobile network traffic is growing rapidly, and service providers must manage their networks efficiently to meet consumer demand. Mobile data offloading is the use of complementary network technologies for delivering data originally targeted for cellular networks. Access network discovery and selection function (ANDSF) is the most complete 3GPP approach to date for controlling offloading between 3GPP (such as HSPA or LTE) and non-3GPP access networks (such as Wi-Fi or WIMAX). The purpose of the ANDSF is to assist user devices to discover access networks in their vicinity and to provide rules (policies) to prioritize and manage connections to all networks. In this paper, we propose a new ANDSF- assisted Wi-Fi regulator method based on end user's high-level motion states, such as driving ,walking, and recognizing whether the user is motionless or not, to avoid unnecessary Wi-Fi scanning and connections. The client-based Wi-Fi connection manager, which performs cyclic Wi-Fi scanning, is compared with the proposed method. According to the performance results, the proposed method shows significant performance enhancement in terms of efficient Wi-Fi control and connectivity with 3G and Wi-Fi.Key words: component; ANDSF, Mobile Data offloading, LTE, Handover, Wi-Fi,WIMAX Reference [1] Cisco, Visual Networking Index: Global Mobile Data Traffic Forecast Update, 2011–2016, February 2012.

Generation of Test Data Using Genetic AlgorithmAbstract: Genetic Algorithm has been implemented to automate the generation of test data. The test data was derived from the program's structure with the aim to traverse every line of code in the software. This work uses fitness function and variables are represented in binary code. The power of using Genetic Algorithm lies in its ability to handle input data which may be of complex structure. Thus, the problem of test data generation is treated entirely as an optimization problem. The advantage of Genetic Algorithm is that through the search and optimization process, test sets are improved. The work has been tested with the help of Triangle Type Classification program.Key words: Genetic Algorithm, Crossover, Mutation, Test Data, Fitness Function Reference [1] Mansour N, Miran Salame," Data Generation for PathTesting", Software Quality Journal, 12, 121–136, 2004,Kluwer Academic Publishers.

105. | Automatic Traffic Information System Without Gps
Automatic Traffic Information System Without GpsAbstract: In a densely populated country like India, traffic and accidents are major problems. To overcome this, the government has to enlarge roads and introduce many infrastructures to reduce the traffic problems, but it's not possible make infrastructural renovations in every requisite place. In order to reduce the traffic and road accidents this project introduces a TRANSCEIVER which is more or less like radar and it also uses a DIRECTION SENSOR – (like "cherry SD1012"). Each vehicle has these two modules and each vehicle transmits and receives the signals of the vehicles around the range of the transceiver (say 500m). With the reception of these signals from the vehicles around the specified range the traffic density can be found and we can prompt the user to take a different route or to slow down their speed using software programs from the received data. In order to know the vehicles that are going in the direction of the user, a direction sensor is used. If N number of vehicles are going in a direction (say north), then the TRANSCEIVER will filter the other signals and it will receive signals only from vehicles which are heading in the same direction, so the number of signals received is directly proportional to the traffic density, there by using algorithms we can instruct the user to either slow down or take detour. Using this same principle, by receiving the data from the upcoming traffic signal, we can also know the status of the signal and using algorithms we can instruct the user to either slow down or speed up, in this case traffic signals from a junction are given directions (north, south, east and west) so only the information of the traffic signal which matches the direction of the users' vehicle will be received and other signals can be attenuated. Thus the DIRECTION and TRANSRECIEVER module together helps to know the locations of vehicles. Once these modules implemented in all vehicles this project finds various applications in ambulance path clearance, traffic police department surveillance, public transports, accident location etc.Key words: Traffic reduction, Automation, Speed ontrol, Transciever, traffic surveillance Reference [1] "ZigBee Wireless Networks and Transceivers" By Shahin Farahani [2] Tung, H.; Tsang, K.; Chui, K.; Tung, H.; Chi, H.; Hancke, G.; Man, K., "The Generic Design of a High Traffic Advance Metering Infrastructure Using ZigBee," Industrial Informatics, IEEE Transactions on , vol.PP, no.99,pp.1,1,0doi: 10.1109/TII.2013.2280084 [3] Aisha Al-Abdallah, A.; Asma Al-Emadi, A.; Mona Al-Ansari, M.; Nassma Mohandes, N.; Malluhi, Q., "Real-time traffic surveillance using ZigBee," Computer Design and Applications (ICCDA), 2010 International Conference on , vol.1, no., pp.V1-550,V1-554,25-27June2010doi : 10.1109/ICCDA.2010.5540694 [4] Wei Shen; Wynter, L., "Real-time road traffic fusion and prediction with GPS and fixed-sensor data," Information Fusion (FUSION), 2012 15th International Conference on , vol., no., pp.1468,1475, 9-12 July 2012 [5] Mittal, A.K.; Bhandari, D., "A novel approach to implement green wave system and detection of stolen vehicles," Advance Computing Conference (IACC), 2013 IEEE 3rd International , vol., no., pp.1055,1059,22-23Feb.2013 doi: 10.1109/IAdCC.2013.6514372 Melvin F., P.

Comparison of Characteristic Curve of Drain-Source Electron Transport Properties in ZnO and GaAs Based MOSFETs Using Monte Carlo SimulationAbstract: The effect of gate length and Thickness on the characteristic curve of drain-source current verse gate voltage in ZnO and GaAs MOSFETs have been simulated. Three transistors with gate lengths of 30, 40 and 50 nm are simulated. Simulations show that with a fixed channel length, when the gate length is increases, the output drain current would be increased, the Moreover, with increasing oxide Thickness the drain current is reduced, which results in the reduced drain barrier lowering. At last, A comparison between thickness and gate lengths of two semiconductors have been discussed.Key words: MOSFET, ZnO, GaAs, Gate Length, Oxide thickness, Drain voltage Reference [1] K.

An Advanced Control Method for Inductive Load of Z-Source InverterAbstract: In this paper, the operation principle of the Z-source inverter is analysed in detail. According to the characteristics of allowed short–shrougt zero state in the Z-source inverter, SPWM control method of the Z-source inverter is obtained by inserting fixed short–shrougt zero state into zero state of SPWM. It is simple and easily implemented in practice. However, in inductive load condition the output voltage and current of Z-source inverter have serious distortion and affect the inverting quality. The cause of this distortion is analysed in detail and an improved SPWM control method is proposed, which can better solve the output voltage and current distortion problem of the Z-source inverter under the condition of inductive load. Matlab simulation results verify that the improved SPWM control method not only eliminates distortion caused by inductive load, but also decreases the switch times and quantities in each cycle. Therefore, it decreases the THD of AC output effectively and improves the efficiency of the inverter, and its theoretical analysis is verified to be effective.Key words: Z-source, inverter, SPWM, the shoot–shrougt zero state, inductive load, voltage distortion Reference [1] Fang zheng peng.

111. | Concrete Made For Energy Conservation Mixed With Sodium Polyacrylates
Concrete Made For Energy Conservation Mixed With Sodium PolyacrylatesAbstract: This study focusses on the heat transfer properties of plain concrete mixed with superabsorbent polymer called sodium polyacrylate. An optimum amount of sodium polyacrylate is used in the concrete mix based on the general concrete strength. There are several advantages of mixing super absorbent polymer in concrete. Some of these advantages are; providing internal water source that helps in the hydration process, internal curing and ultimately increases the concrete strength, providing additional voids due to drying process in the concrete mass, and improving the insulation properties of concrete. The additional water voids affect the concrete strength negatively; at the same time improve the concrete performance by improving the concrete workability and place ability, reducing the concrete susceptibility to freezing thawing cycles, reducing shrinkage, and improving the fresh concrete stability. Several batches were prepared to determine the most effective amount of sodium polyacrylate to use in the concrete mix.Key words: Concrete Durability, Hydration, Internal Curing, Sodium Polyacrylate, Hot box, Thermal conductivity.

112. | Application of K-Nearest Neighbor (KNN) Approach for Predicting Economic Events: Theoretical Background
Application of K-Nearest Neighbor (KNN) Approach for Predicting Economic Events: Theoretical BackgroundAbstract: In the present study k-Nearest Neighbor classification method, have been studied for economic forecasting. Due to the effects of companies' financial distress on stakeholders, financial distress prediction models have been one of the most attractive areas in financial research. In recent years, after the global financial crisis, the number of bankrupt companies has risen. Since companies' financial distress is the first stage of bankruptcy, using financial ratios for predicting financial distress have attracted too much attention of the academics as well as economic and financial institutions. Although in recent years studies on predicting companies' financial distress in Iran have been increased, most efforts have exploited traditional statistical methods; and just a few studies have used nonparametric methods. Recent studies demonstrate this method is more capable than other methods.Key words: Predicting financial distress- Machine learning- k-Nearest Neighbor. Reference [1] Audibert, J.Y. & Tsybakov, A.B.

Curing Acceleration of Concrete Bricks by Using Chemical AdmixtureAbstract: The study was carried out to assess the effect of chemical admixture on the curing of concrete bricks. The effect was assessed in terms of compressive strength gained by the bricks during predetermined period in days. After manufacture, the batches of bricks cured by conventional method. Four sample batches were prepared viz. 0.0, 1.0, 1.5, 2.0 percentage of chemical admixture of the cement used. The compressive strength of the bricks was made on compression testing machine. The plot of the average compressive strength of each batch versus curing time in days obtained on the basis of findings during the tests. It was found that the use of the chemical admixtures improves the rate of curing and helps the concrete to gain earlier strength.Key words: Chemical Admixture, Compressive Strength, Concrete bricks, Curing, Hydration.

Air Bag: A Safety Restraint System of an AutomobileAbstract: The present paper represents a brief review of life saving system in roll- over accidents, while driving on the road by a four wheeler. An Airbag is an automotive safety restraint system for an occupant as well as passengers. The system consists of a flexible fabric envelope or cushion, designed to inflate rapidly during an automobile collision. Its purpose is to cushion occupants during a crash and provide protection to their bodies when they strike interior objects such as the steering wheel or a window etc. Thus it lowers the number of injuries by reducing the force exerted by steering wheel, windows and the dashboard at any point on the body. Continuing research and developments are going on in its module design, combustible material, air bag fabric design and material, coating etc. in making this life saving safety device further efficient. However, success of any safety restraint device depends on its correct implementation and certain safety rules to be followed.Key words: Air bag, Collision, Occupant, Fatal injury, Safety, Passenger.

117. | A Novel Approach to Cloud Computing Security over Single to Multi Clouds
A Novel Approach to Cloud Computing Security over Single to Multi CloudsAbstract: The usage of cloud computing has increased speedily in the society. Cloud computing presents many benefits in terms of accessibility of data and low cost. A main characteristic of the cloud services is that users' data are usually processed remotely in unknown machines that users do not operate. It can be converted into a significant roadblock to the wide adoption of cloud services. Make sure that the security of cloud computing is a main factor in the environment of cloud computing, as users repeatedly store perceptive information with cloud storage providers but these providers may be untrusted. Dealing with "single cloud" providers is expected to become less accepted with customers due to risks of service accessibility collapse and the possibility of malicious insiders in the single cloud. A movement towards "multi-clouds", or in other words, "interclouds" or "cloud-of-clouds" has come into view recently. The growing popularity of cloud storage space services has show the way companies that handle critical data to think about using these services for their storage space needs. However the reliability and security of data stored in the cloud still remain main concerns. It is found that the investigation into the use of multi-cloud providers to maintain security has acknowledged less thought from the research community has the use of single clouds. My work aims to support the use of multi-clouds due to its capability to decrease security risks that affect the cloud computing user.Index Terms: Cloud computing, DepSky Architecture single cloud, multi-clouds, cloud storage, data integrity, data intrusion, service availability.

Estimation of Ground and Excited State Dipole Moments of Some Laser DyesAbstract: The ground state (μg) and the excited state (μe) dipole moments of three laser dyes namely 5-chloro-2-phenylindole (CPI), 5-methyl-2-phenylindole (MPI) and 1, 3-diphenyl benzene (MT) were studied at room temperature in various solvents. The ground state dipole moments (μg) of all the three laser dyes were determined experimentally by Guggenheim method. The excited state dipole moments (μe) were estimated from Lippert's, Bakshiev's and Chamma Viallet's equations by using the variation of the Stokes shift with the solvent dielectric constant and refractive index. Ground and excited state dipole moments were evaluated by means of solvatochromic shift method and also the excited state dipole moments are determined in combination with ground state dipole moments. It was observed that dipole moment values of excited states (μe) were higher than corresponding ground state values (μg), indicating a substantial redistribution of the π-electron densities in a more polar excited state for all the dyes investigated.Key words: Laser dyes; Ground state dipole moments; Excited state dipole moments; Solvatochromic shift method Reference [1] P.

119. | A Mitigation Technique for Inrush Currents in Load Transformers for the Series Voltage Sag Compensator
A Mitigation Technique for Inrush Currents in Load Transformers for the Series Voltage Sag CompensatorAbstract: In many countries, high-tech manufacturers concentrate in industry parks. Survey results suggest that 92% of interruption at industrial facilities is voltage sag related. An inrush mitigation technique is proposed and implemented in a synchronous reference frame sag compensator controller. The voltage sag compensator consists of a three phase voltage source inverter and a coupling transformer for serial connection. It is the most cost effective solution against voltage sags. When voltage sag happen, the transformers, which are often installed in front of critical loads for electrical isolation, are exposed to the disfigured voltages and a DC offset will occur in its flux linkage. When the compensator restores the load voltage, the flux linkage will be driven to the level of magnetic saturation and severe inrush current occurs. The compensator is likely to be interrupted because of its own over current protection. This paper proposes an inrush current mitigation technique together with a state-feedback controller for the Voltage sag compensator.Key words: Voltage sag, Flux linkage, inrush current, Transformer, power quality, voltage sag compensator Reference [1] D.

120. | The Spinning Motion of a Gyrostat under the Influence of Newtonian Force Field and a Gyrostatic Moment Vector
The Spinning Motion of a Gyrostat under the Influence of Newtonian Force Field and a Gyrostatic Moment VectorAbstract: In this paper, the rotational motion of a gyrostat about a fixed point in a central Newtonian force field is considered. This body is acted upon by a gyrostatic moment vector . We consider the motion of the body in a case analogous to Lagrange's case. The analytical periodic solutions of the equations of motion are obtained using the Poincaré's small parameter method. A geometric interpretation of motion is given by using Euler's angles to describe the orientation of the body at any instant of time. The graphical representations of these solutions are presented when the different parameters of the body are acted. The fourth order Runge-Kutta method is applied to investigate the numerical solutions of the autonomous system. A comparison between the analytical and the numerical solutions shows a good agreement between them and the deviations are very small.

122. | Experimental Analysis of OLSR Routing Protocol and Performance Evaluation Using NS-2 Simulator
Experimental Analysis of OLSR Routing Protocol and Performance Evaluation Using NS-2 SimulatorAbstract: Mobile ad hoc networks (MANETs) is a collection of wireless moving nodes which communicate with each other and exchange data without any fixed base station or without the need of any kind of wired backbone network. These design characteristics make routing in wireless network a critical issue as routing protocols adopted in wireless network is completely different from wired network in which a backbone router determines the routing path. In this paper we discussed a OLSR routing protocol for routing path determination as well as we measured the various performance oriented parameters using NS2 simulator. During the research implementations, we also use trace graph, a open source tool for generation of graphs of various statistics such as end to end delay, jitter, throughput etc. This study presents the sequence of steps which highlight the adoption of OLSR routing based on the number of nodes and statistics generated in simulation environment.Key words: MANET, OLSR, NS2, Throughput, Delay, Packet Delivery Ratio Reference [1] J.Macker,"mobile ad hoc Networking (MANET): routing protocol performance issues and Evaluation considerations".IETF RFC 2501, January 1999.

123. | Avoidance of Ranking Capabilities in Retrieval of Queries on Hidden-Web Text Databases
Avoidance of Ranking Capabilities in Retrieval of Queries on Hidden-Web Text DatabasesAbstract: Many online or local data sources provide powerful querying mechanisms but limited ranking capabilities. For instance, Pub Med allows users to submit highly expressive Boolean keyword queries, but ranks the query results by date only. However, a user would typically prefer a ranking by relevance, measured by an information retrieval (IR) ranking function. A naive approach would be to submit a disjunctive query with all query keywords, retrieve all the returned matching documents, and then re-rank them. Unfortunately, such an operation would be very expensive due to the large number of results returned by disjunctive queries. In this paper, we present algorithms that return the top results for a query, ranked according to an IR-style ranking function, while operating on top of a source with a Boolean query interface with no ranking capabilities (or a ranking capability of no interest to the end user). The algorithms generate a series of conjunctive queries that return only documents that are candidates for being highly ranked according to relevance metric. Our approach can also be applied to other settings where the ranking is monotonic on a set of factors (query keywords in IR) and the source query interface is a Boolean expression of these factors. Our comprehensive experimental evaluation on the Pub Med database and a TREC data set show that we achieve order of magnitude improvement compared to the current baseline approaches.Index Terms: Hidden-web databases, keyword search, top-k ranking Reference [1] RamezElmasri, ShamkantB.

Metacluster Model Using an Aggregate Function In The Presence Of Data Domain MembershipAbstract: Once with the exponential increase of data generated by the business environment, the need of rapid, precise and robust algorithms appeared in data analysis. The improvements given by database technologies, computational performances and artificial intelligence have contributed to the development of intelligent data analysis. The principal clustering methods are presented in comparison. A technique for object grouping validation generated by the clustering methods is proposed and applied on a dataset a priori classified according to their domain membership.

126. | Vehicular Route Prediction In City Environment Based On Statistical Models
Vehicular Route Prediction In City Environment Based On Statistical ModelsAbstract: Travel route analysis and prediction are essential for the success of many applications in Vehicular Ad-hoc Networks (VANETs). It is challenging to make accurate route prediction for general vehicles in city settings due to several practical issues such as very complicated traffic networks, the highly dynamic real-time traffic conditions and their interaction with driver's route selections. The traffic conditions on complicated road networks keep changing from time to time. Inspired by the observation that a vehicle often has its own route selection flavour when traversing between its sources and destinations, here it defines a mobility pattern as a consecutive series of road segment selections that exhibit frequent appearance along all the itineraries of the vehicle. Here with the help statistical models like Markov Model with only first order Markov Model (MM) to choose only the next intersection point of the road segment with only one pattern without considering traffic conditions again by using the Hidden Markov Model(HMM) to predict next intersection point by considering traffic conditions with shortest distance and obstacle and Variable-order Markov Model (VMM) to select mobility patterns from the source to destination which is chosen by the driver by considering the traffic conditions .Key words: MM, HMM, VMM, RSU, OBU.

127. | A Systematic Methodology for the Detection and Correction of Soft Errors
A Systematic Methodology for the Detection and Correction of Soft ErrorsAbstract: Continuous shrinking in feature size, increasing power density etc, increases the vulnerability of microprocessors against soft errors even in terrestrial applications. The register file is one of the essential architectural components where soft errors can be very mischievous because errors may rapidly spread from there throughout the whole system. Thus, register files are recognized as one of the major concerns when it comes to reliability. The project introduces Self-Immunity, a technique that improves the integrity of the register file with respect to soft errors. Based on the observation that a certain number of register bits are not always used to represent a value stored in a register. The project deals with the difficulty to exploit this obvious observation to enhance the register file integrity against soft errors. It shows that our technique can reduce the vulnerability of the register file considerably while exhibiting smaller overhead in terms of area and power consumption compared to state-of-the-art in register file protection. For embedded systems under stringent cost constraints, where area, performance, power and reliability cannot be simply compromised, it proposes a soft error mitigation technique for register files. Xilinx-ISE tool for synthesizing and the VHDL language is used.Key words: Error Correction Code, Self-Immunity Technique, Register file Integrity, Vulnerability Reference [1] Greg Bronevetsky and Bronis R. de Supinski,"Soft ErrorVulnerability of Iterative Linear Algebra Methods," in the 22ndannual international conference on Supercomputing, pp. 155-164,2008.

129. | Comparison in Wavelets for Dynamic Monitoring Of Voltage Fluctuation & Flicker
Comparison in Wavelets for Dynamic Monitoring Of Voltage Fluctuation & FlickerAbstract: Voltage fluctuation is depicted as a sequence of root mean square voltage changes or a cyclic difference of the voltage waveform envelopeThe non-resistive loads used in the power system are the major source of fluctuation. Such fluctuating loads include arc furnaces, rolling mill drives, and main winder. All of these have loads with a high rate of change of power with respect to the short-circuit capacity at the point of common coupling (PCC). Small power loads also can be sources of flicker, such as starting of induction motors, welders, boilers, power regulators, electric saws and hammers, pumps and compressors, cranes, and elevators. In power systems, a number of harmful technical problems occur due to voltage fluctuation, resulting in disturbance to production processes and considerable costs. But flicker has its negative physiological results, which can affect worker safety as well as productivity.

Cross-Layer Based Secure Routing In ManetsAbstract: The security of wireless networks has been a constant topic in the recent years. With the advance of wireless networks, building reliable and secure communication is becoming extremely important. Security is an essential requirement in Mobile Ad-hoc Networks (MANETs) to provide protected communication between mobile nodes. In this paper, we propose a novel security mechanism: Cross-layer based Secure Routing in MANETs (CSR-MAN). Cross-layer design is a promising method to satisfy the network requirements which has gained its popularity during the recent years. A cross-layer based secure routing mechanism is proposed in this paper which includes passing of the information from physical layer and MAC layer to the network layer. The route is selected based on the parameters obtained from the lower layers. An evaluation of this mechanism has been provided using simulations with ns-2. The simulation results illustrate good comparison of network performance parameters for different conditions.Key words: Cross-layer, MANETs, Routing, Security Reference [1] Todd R.

Monte Carlo Simulation in InAsxP1-X, InAs and InP at High Field ApplicationAbstract: We study how electrons, initially in thermal equilibrium, drift under the action of an applied electric field within bulk zincblende InAsxP1-x, InAs and InP. Calculations are made using a non-parabolic effective mass energy band model, Monte Carlo simulation that includes all of the major scattering mechanisms. The band parameters used in the simulation are extracted from optimized pseudopotential band calculations to ensure excellent agreement with experimental information and ab-initio band models. The effects of alloy scattering on the electron transport physics are examined. For all materials, it is found that electron velocity overshoot only occurs when the electric field is increased to a value above a certain critical field, unique to each material. This critical field is strongly dependent on the material parameters.Key words: Non-parabolic; pseudopotential; alloy scattering; velocity overshoot Reference [1] K. Brennan, K. Hess, J. Y.

According to the spectroscopic study, the synthesized azo dye is thought to be existing as two tautomers which are the azo phenol tautomer and the hydrazo keto tautomer. This finding was supported by the fact that the vibrational band of the phenolic hydroxyl group was seen at 3480 cm1 along with the absorption band of an ,-unsaturated ketone at 1700 cm1 and the azo vibrational band at 1540 cm1 in the IR spectrum.

Design and Implementation of Quad Core Architecture Using FPGAAbstract: The quad processor core is a design philosophy that has become a mainstream in Scientific and engineering applications. Increasing performance and gate capacity of recent FPGA devices permit complex logic systems to be implemented on a single programmable device. The Embedded multiprocessors face a new problem with thread safety [5]. It is caused by the shared memory, when thread safety is violated the processors can access the same value at the same time. Basically the processor performance can be increased by adopting clock scaling technique [4] and micro architectural enhancements. Therefore, designed a new Architecture called quad processor core architecture for SOC applications. This is implemented on the FPGA chip using VHDL.This architecture performs a simultaneous use of both parallel and distributed computing. The full architecture of a Quad processor core designed for realistic to perform arithmetic, logical, shifting and bit manipulate operations. The proposed quad processor core contains Homogeneous RISC processors [3],[7] added with pipelined processing units, multibus organization and I/o ports along with the other functional elements required to implement embedded SoC solutions.

Space Vector Based Random Pwm Algorithms Based Direct Torque Controlled Induction Motor DriveAbstract: In this proposed paper, to get fast transient response, DTC algorithm has to be developed for an /induction motor. Then, to get constant frequency, hysteresis controllers have to be replaced with space vector PWM (SVPWM) modulator. However, the SVPWM algorithm gives more harmonic distortion. Hence, to reduce the complexity involved in classical SVPWM algorithm and acoustical noise, various spread spectrum modulation methods which are also known as random pulse width modulation algorithms, have to be developed by using the instantaneous phase voltages only. The proposed paper mainly focuses on the generation of a family of spread spectrum modulation methods by using both space vector approach. To validate the proposed algorithms, several numerical simulation studies have been developed by using Matlab-Simulink. Finally the simulation results are compared with the existing methods.Key words: Induction Motor, Total Harmonic Distortion,Direct Torque Control,Space Vector PWM,Random PWM Reference [1].

140. | Implementation of Pipeline Architecture for High-Speed Computation of the Discrete Wavelet Transform Using HDL
Implementation of Pipeline Architecture for High-Speed Computation of the Discrete Wavelet Transform Using HDLAbstract: In this paper, a scheme for the design of a high-speed pipeline VLSI architecture for the computation of the 2-D discrete wavelet transform (DWT) is proposed. The main focus in the development of the architecture is on providing a high operating frequency and a small number of clock cycles along with efficient hardware utilization by maximizing the inter-stage and intra-stage computational parallelism for the pipeline. The inter-stage parallelism is enhanced by optimally mapping the computational task of multi decomposition levels to the stages of the pipeline and synchronizing their operations. The intra-stage parallelism is enhanced by dividing the 2-D filtering operation into four subtasks that can be performed independently in parallel and minimizing the delay of the critical path of bit-wise adder networks for performing the filtering operation. To validate the proposed scheme, a circuit is designed, simulated, and implemented in FPGA for the 2-D DWT computation. The results of the implementation show that the circuit is capable of operating with a maximum clock frequency of 80.749MHz and processing 1022 frames of size 512 × 512 per second with this operating frequency. It is shown that the performance in terms of the processing speed of the architecture designed based on the proposed scheme is superior to those of the architectures designed using other existing schemes, and it has similar or lower hardware consumption.Key words: Computational parallelism, Discrete Wavelet Transform FPGA implementation, Image Processing, Multi-resolution filtering, Non-separable approach, Parallel architecture.

A Survey: Content Based Image Retrieval Based On Color, Texture, Shape & Neuro FuzzyAbstract: In current technology the acquisition, transmission, storing, and manipulation are allowed on the large collections of images. With the increase in popularity of the network and development of multimedia technologies, users are not satisfied with the traditional information retrieval techniques. So nowadays, the content based image retrieval is becoming a source of exact and fast retrieval. Content Based Image Retrieval (CBIR) is a technique which uses visual features of image such as color, shape, texture, etc. to search user required image from large image database according to user's requests in the form of a query image. Images are retrieved on the basis of similarity in features where features of the query specification are compared with features from the image database to determine which images match similarly with given features. Feature extraction is a crucial part for any of such retrieval systems. So far, the only way of searching these collections was based on keyword indexing, or simply by browsing. Literature survey is most important for understanding and gaining much more knowledge about specific area of a subject. In this paper we survey some technical aspects of current content-based image retrieval systems and described the image segmentation in image processing and the features like neuro fuzzy technique, color histogram, texture, and shape for accurate and effective Content Based Image Retrieval System after doing the deep study of related works.Key words: Content-Based Image Retrieval (CBIR), Neuro Fuzzy, Color Histogram, Texture, HSV Color and Wavelet decomposition, Image Segmentation Reference [1] Ying Liua , Dengsheng Zhanga, Guojun Lua, Wei-Ying Mab, "A survey of content-based image retrieval with high-level semantics", The journal of the Pattern Recognition society, Pattern Recognition 40 (2007) 262–282.

150. | Fuzzy Controller Based Seven Level Modified H-Bridge Inverter For Grid Connected PV System
Fuzzy Controller Based Seven Level Modified H-Bridge Inverter For Grid Connected PV SystemAbstract: This paper proposes a single-phase seven-level inverter for grid-connected photovoltaic systems, with a novel pulse width-modulated (PWM) control scheme. Three reference signals that are identical to each other with an offset value that is equivalent to the amplitude of the triangular carrier signal were used to generate the PWM signals. The inverter is capable of producing seven levels of output-voltage levels (Vdc, 2Vdc/3, Vdc/3, 0, −Vdc, −2Vdc/3, −Vdc/3) from the dc supply voltage. And it recounts the development of a novel modified Hbridge single-phase multilevel inverter that has two diode embedded bidirectional switches and a novel pulse width modulated (PWM) technique. The topology was applied to a grid-connected photovoltaic system with considerations for a maximum-power-point tracker (MPPT) and a current-control algorithm. Multilevel inverters offer improved output waveforms and lower THD. The circuit topology, modulation law, and operational principle of the proposed inverter were analyzed in detail. A FUZZY control is implemented to optimize the performance of the inverter. MATLAB/SIMULINK results indicate that the THD of the Fuzzy Controller Circuit is much lesser. Furthermore, both the grid voltage and the grid current are in phase at nearunity power factor. By controlling the modulation index, the desired number of levels of the inverter's output voltage can be achieved. The less THD in the seven-level inverter compared with that in the five- and threelevel inverters is an attractive solution for grid-connected PV inverters.INDEX TERMS: Grid connected Photovoltaic system, Maximum power point tracking system, Single phase seven level inverter and fuzzy logic controller.

Simulation Using Quazi Linearization of Homogeneous Transient Model of Vapor Liquid Two Phase Flow inside EvaporatorAbstract: A homogeneous model for prediction of the transient performance of an evaporator with vapor liquid two phase flow inside is presented. The model is capable of predicting the refrigerant temperature distribution, velocity of refrigerant, tube wall temperature as a function of position and time. An efficient finite difference method is proposed to obtain the numerical solution of the model without solving a large set of non-linear equations simultaneously. A single tube evaporator with refrigerant R22 as working fluid was chosen as a sample and some tests were carried out to determine its transient response. The examination of results indicates that the theoretical model provides a reasonable prediction of dynamic response which is useful in designing a controllable compressor to reduce power consumption. Transient behavior of temperature of refrigerant has been obtained using MATLAB programs.Key words: Vapor liquid two phase flow, Homogeneous Model, set of non linear equations, finite difference method, and MATLAB program Reference [1] G.

Design of Approximate Multiplier for Error-Tolerant ApplicationsAbstract: CMOS scaling has reached to the level, where process variation has become significant problem hindering further scaling. Various approaches to mitigate process variation effect try to nullify at the cost of increased area/power consumption. There are some applications which accept small errors such as multimedia processing. Designing accurate circuit for these applications is waste of area/power. This paper proposes low power, high speed approximate multiplier. The proposed multiplier outperforms and provides significant improvement in power, area, and delay at the cost of little degrade in accuracy. Experimental result shows that the proposed multipliers consume less power and require less area compared to conventional truncated multiplier.Key words: CMOS technology, error-tolerant, low power, multiplier, truncation.

Adsorption of Cu (II) Ions from Aqueous Solution by Hydrochloric Acid, Hydrofluoric Acid Treated Lignite Fly AshAbstract: The adsorption of toxic compounds from industrial wastewater is an effective method for both treating these effluents. In this context, the lignite fly ash was demineralised using concentrated HCl (FA-HCl) and HF (FA-DEM) and were used as adsorbents for Cu(II) ions from aqueous solutions. Batch experiments were carried out under various adsorbent dosages, pH, contact time and different metal ion concentrations. For FA-HCl, the adsorption percentage of Cu(II) ions was 76.92% and for FA-DEM, the adsorption percentage of Cu(II) ions was 48.23% achieved under the optimum conditions of adsorbent dosages, pH, temperature, the contact time and the influence of other metals. The adsorption of Cu(II) ions onto FA-HCl and FA-DEM followed the pseudo second order kinetics. The Langmuir isotherm model best represented the equilibrium data for both the adsorbents compared to other studied adsorbents. Influence of Ni(II) ions and Zn(II) ions on adsorption of Cu(II) ions on FA-HCl and FA-DEM in binary and tertiary systems showed certain decrease on adsorption of Cu(II) ions.Key words: Fly ash, Adsorption, Kinetics, Isotherm.

162. | Power Factor Correction By Interleaved Boost Converter Using PI Controller
Power Factor Correction By Interleaved Boost Converter Using PI ControllerAbstract: The equipment connected to an electricity distribution network usually needs rectification. The conventional single phase diode rectifier uses a large electrolytic capacitor to reduce DC voltage ripple, which produces a non-sinusoidal line current. So power factor correction (PFC) techniques are gaining increasing attention. The boost topology is most popular than others in PFC applications. This paper presents a two-phase interleaved boost converter which ensures 180˚ phase shift between the two interleaved converters. The PI controller is used to reshape the input current so as to reduce the harmonics.Key words: Average Current mode control, Boost converter, Interleaved Boost converter, PI controller, Power factor.

163. | Effect of Modulation on the Onset of Thermal Convection in a Viscoelastic Fluid-Saturated Nanofluid Porous Layer Effect of Modulation on the Onset of Thermal Convection in a Viscoelastic Fluid-Saturated Nanofluid Porous LayerAbstract: The stability of a viscoelastic fluid-saturated by a nanofluid in a horizontal porous layer, when the boundaries of the layer are subjected to periodic temperature modulation, is analyzed. The Darcy-Brinkman-Oldroyd-B fluid model is employed and only infinitesimal disturbances are considered. The model used for the nanofluids incorporates the effect of Brownian motion. The thermal conductivity and viscosity are considered to be dependent on the nanoparticle volume fraction. Three cases of the oscillatory temperature field were examined (a) symmetric, so that the wall temperatures are modulated in phase, (b) asymmetric corresponding to out-of phase modulation and (c) only the bottom wall is modulated. Perturbation solution in powers of the amplitude of the applied field is obtained. The effect of the frequency of modulation on the stability is clearly shown. The stability of the system characterized by a correction Rayleigh number is calculated as a function of the viscoelastic parameters, the concentration Rayleigh number, porosity, Lewis number, heat capacity ratio, Vadász number, viscosity and conductivity variation parameters and frequency of modulation. It is found that the onset of convection can be delayed or advanced by the factors represented by these parameters. The nanofluid is found to have more stabilizing effect when compared to regular fluid. The effect of all three types of modulation is found to be destabilizing as compared to the unmodulated system.Reference [1] Xuan YM, Li Q: Investigation on convective heat transfer and flow features of nanofluids.

Investigation of Aniline Adsorption onto Spherical Carbon: Optimization Using Response Surface MethodologyAbstract: In the present study, spherical carbon was used to optimize the removal efficiency for aniline by using Response Surface Methodological approach. The carbon sample was obtained by the commercial activated spherical carbon and treated with phosphoric acid and sodium hydroxide. The surface structure of spherical carbon was analysed by Scanning Electron Microscopy coupled with Energy Dispersive X-ray Analysis. The effect of four parameters, that is, pH of the solution (2-11), initial aniline concentration (10-70 mg/L), temperature (25-55°C) and adsorbent dose (0.02-0.3 g/100 mL) was optimized for the removal of aniline. A Box-Behnken experimental design was employed for the optimization of adsorption of aniline on spherical carbon to ensure high adsorption efficiency in a low adsorbent dose and high initial aniline concentration. The analysis of variance showed a high coefficient of determination value (R2 = 0.9749) and satisfactory prediction second-order model was derived. Maximum aniline removal efficiency was predicted and experimentally validated.Key words: Aniline, Adsorption, Box-Behnken design, Response Surface methodology, Spherical carbon. Reference [1]. K.

Effect of MHD on Jeffery-Hamel Flow in Nanofluids by Differential Transform MethodAbstract: In this paper, the problem of Jeffery-Hamel flow of nanofluid with magnetic effect is analyzed. The basic governing equations which are highly nonlinear are solved analytically using a semi-numerical-analytical technique called differential transform method (DTM) and numerically using Runge-Kutta shooting method (RKSM). The principle of differential transformation is briefly introduced, and then applied for the aforementioned problem. Results for velocity filed in a divergent channel are presented for various values of nanoparticle solid volume fraction, Hartmann number and Reynolds number. The values obtained by DTM and RKSM are agree to the order of 10-5. Further the values obtained by DTM are justified by comparing with the values obtained by Moghimi et al. [1,2] and Sheikholeslami et al. [3] and the values agree to the order of 10-5, 10-5 and 10-4 respectively.Key words: Jeffery-Hamel flow, MHD, nanofluid, Differential Transform method. Reference [1].

166. | Adaptive Filter Based On TDBLMS Algorithm for Image Noise Cancellation
Adaptive Filter Based On TDBLMS Algorithm for Image Noise CancellationAbstract: Images are often degraded by noises. Noise can occur during image capture, transmission, etc. Noise removal is an important task in image processing. In general the results of the noise removal have a strong influence on the quality of the image processing technique. Several techniques for noise removal are well established in color image processing. The nature of the noise removal problem depends on the type of the noise corrupting the image. An adaptive filter for two-dimensional block processing in image noise cancellation is proposed in this paper. The processing includes two phases. They are the weight-training phase and the block-adaptation phase. The weight-training phase obtains the suitable weight matrix to be the initial one for the block-adaptation phase such that a higher signal-to-noise ratio can be achieved. To verify the feasibility of this approach, the simulation with the block sizes of 4 x 4, 8 x 8, 16 x 16, and 32 x 32 are performed. The simulation results show that this approach performs well.Key words: Adaptive filter, Adaptive algorithm, Least squares approximation, Noise cancellation, PSNR Reference [1] S.

167. | Effect of first order chemical reaction in a vertical double-passage channel
Effect of first order chemical reaction in a vertical double-passage channelAbstract: Fully developed laminar mixed convection flow in a vertical channel in the presence of first order chemical reactions has been investigated. The channel is divided into two passages by means of a thin, perfectly plane conducting baffle and hence the velocity, temperature and concentration will be individual in each stream. The coupled, nonlinear ordinary differential equations are solved analytically using regular perturbation method valid for small values of Brinkman number. The effects of thermal Grashoff number, mass Grashoff number, Brinkman number and chemical reaction parameter on the velocity, temperature and concentration fields at different positions of the baffle are presented and discussed in detail. The increase in thermal Grashof number, mass Grashoff number and Brinkman number enhances the flow, whereas the chemical reaction parameter suppress the flow at all baffle positions.Reference [1] Merkin JH (1980) Mixed convection boundary layer flow on a vertical surface in a saturated porous medium.

168. | Performance Improvement Of Self-Aspirating Porous Radiant Burner By Controlling Process Parameters
Performance Improvement Of Self-Aspirating Porous Radiant Burner By Controlling Process ParametersAbstract: This paper presents the heat transfer characteristics of a self-aspirating porous radiant burner (SAPRB) that operates on the basis of an effective energy conversion method between flowing gas enthalpy and thermal radiation. The temperature field at various flame zones was measured experimentally by the help of both FLUKE IR camera and K-type thermocouples. The experimental setup consisted of a two layered domestic cooking burner, a flexible test stand attached with six K-type thermocouples at different positions, IR camera, LPG setup and a hot wire anemometer. The two layered SAPRB consisted of a combustion zone and a preheating zone. Time dependent temperature history from thermocouples at various flame zones were acquired by using a data acquisition system and the temperature profiles were analyzed in the ZAILA application software environments. In the other hand the IR graphs were captured by FLUKE IR camera and the thermographs were analyzed in the SMARTView software environments. The experimental results revealed that the homogeneous porous media, in addition to its convective heat exchange with the gas, might absorb, emit, and scatter thermal radiation. The rate of heat transfer was more at the center of the burner where a combined effect of both convection & radiation might be realized. The maximum thermal efficiency was found to be 64% which was having a good agreement with the previous data in the open literature.Key words: IR Thermography, LPG, Self-Aspirating Porous Radiant Burner (SAPRB), Thermal Efficiency, Transient Temperature.

Comparison of Fenton and Anaerobic Process in Treating Mature Landfill LeachateAbstract: Mature landfill leachate from Vilapilsala site was subjected to both anaerobic and Fenton process separately. After Fenton treatment removal of COD, BOD, turbidity, nitrate, sulphate and TSS were 92.1%, 83.5%, 94.2%, 18.86%, 11% and 96.6% respectively (optimized treatment conditions pH 3, reaction time 30min, H2O2/COD ratio 3, [H2O2]/[Fe2+] ratio 15 and 3g/L sludge recycling). Biodegradability enhanced from 0.3 to 0.65 and acute toxicity reduced to 6.3% from initial 3.2%. Whereas by anaerobic treatment at an HRT of 11days and pH 7, removal of COD, BOD, turbidity, nitrate, sulphate and TSS were 40.5%, 50.0%, 23.5%, 46.2%, 35.3% and 37% respectively. Biodegradability reduced from 0.3 to 0.26 and acute toxicity remained almost the same. Economic analysis revealed that initial cost will come around 50,978/- for Fenton process and Rs.11,16,555/- for anaerobic process in batch mode. Operating cost was around 1,23,240/m3 wastewater for Fenton process and it came only around 527/m3 for anaerobic process.Key words: Acute Toxicity, Anaerobic Process, Biodegradability, Fenton Process, Mature landfill leachate Reference 1] Barjinder Bhalla, M.S.Saini and M.K.Jha, Characterization of Leachate from Municipal Solid Waste (MSW) Landfilling Sites of Ludhiana, India: A Comparative Study, International Journal of Engineering Research and Applications,2(6), 2012, 732-745.

170. | Performance /efficiency enhancement of Dynamic Source Routing Protocol in Wireless Mesh Networks
Performance /efficiency enhancement of Dynamic Source Routing Protocol in Wireless Mesh NetworksAbstract: A Wireless Mesh Network is a collection of wireless nodes that form a network connection. There are several routing protocols like TORA, HEAT, AODV and DSR etc. which have been designed for providing communication among all the nodes in the wireless network. DSR is a reactive routing protocol and comfortable for unlimited number of nodes. This paper presents the comparison performance of DSR protocol with E-DSR (enhanced-DSR) protocol. In the enhanced approach of DSR, we improve the performance of Packet Delivery Ratio and throughput of the Wireless Mesh Networks. In E-DSR the destination a node recognizes first route request message (RREQ), it produces Turn-Around route request (TA-RREQ) message and deluges it to neighbor nodes within transmission range. E-DSR decreases route fail variation messages and gets very good performance as compared to Dynamic Source Routing protocol (DSR).Key words: WMNs, Packet Delivery Ratio, HEAT, E-DSR, RREQ (Route Request), RREP (Route Reply); Reference [1] C.

173. | Static and Dynamics Drape Of Fabric: An Emerging Arena of Fabric Evaluation
Static and Dynamics Drape Of Fabric: An Emerging Arena of Fabric EvaluationAbstract: Drape is one of the most important fabric properties from designer as well as end user point of view. The standard method of drape measurement is as per IS 8357:1977. This can be classified as static drape. In today's scenario, across all the areas, advancement of technology is remarkable. There is little doubt that the influence of technology has overtaken our lives. In the manufacturing field, technology solves a number of problems related to design, production and dispatching of products, providing the consumer with either low cost or large varieties of enhanced, sophisticated or unique products depending on the direction and philosophy of the company and its marketing strategy. One has to learn to co-exist with technology so are industries and it is not who will use the technology to combat competition in the world of markets of the future that is crucial, but rather who will develop new technologies to stay competitive. Dynamic drape behavior and simulations are gaining more and more popularity day by day. It is so, because it gives to some extent close to real life situation. Many research worker in abroad are working on the same since last decade, but unfortunately very few information, particularly data base information are available here. No readymade instrument is available here to study the dynamic drape behaviour of fabric.Key words: drape, static drape, dynamic drape, instrument, simulation Reference [1].

174. | Dynamic Drape Behavior of Textile Fabric: Part I - Development of an Instrument and Its Implications
Dynamic Drape Behavior of Textile Fabric: Part I - Development of an Instrument and Its ImplicationsAbstract: There are instruments available to measure the drape coefficient of fabric. The most widely accepted method (IS 8357:1977) is hang a circular fabric sample and measure the drape coefficient. This measurement technique gives quite a bit of fair idea about drape coefficient of a fabric in static condition. But when it's static condition is disturbed as the case in practical application of fabric in the form of using as garment or in the form of any domestic application like using it as curtain or table cloth, it's shape of fabric fall pattern i.e nodes in term of drape terminology changes. Therefore, to get some idea about the effect of above mentioned static condition to dynamic condition of the fabric, a need was felt to have some sort of simulation. Here simulation might not be possible exactly to the practical condition, but one can think of some sort of simulation, similar to it and find out the effect of the same on drape properties of fabric. Therefore, it was thought that some simple, inexpensive, easy to handle instrument would be developed to measure the dynamic drape coefficient of fabric. The present work is the result of the same.Key words: drape, drape coefficient, instrument, dynamic drape, simulation Reference [1]. Peirce, F.T., (1937) The geometry of cloth structure.

175. | Dynamic Drapen Behavior of Textile Fabric: Part II - Attributes of Various Fabric Parameters
Dynamic Drapen Behavior of Textile Fabric: Part II - Attributes of Various Fabric ParametersAbstract: Substantial amount of work has been done on static drape behavior of fabric by Cusick in 60s. In 70s & 80s, it was felt that drape is not much important. Therefore the main focus during this period was on tensile behavior of the fabric. But during 90s, due to rapid growth of readymade garment along with computerized manufacturing system, it was felt by various research workers and market surveyors that drape is very important property. So, one need to look into the matter to give proper shape to a garment after its cutting and sewing. Moreover, to meet the customer requirement and stringent competition from the market one need to give the best quality of the fabric, so that when one uses the fabric its drape property does not change much from morning to evening. The crease resistant fabric with special finish has come into existence because of this development. Therefore a need was felt on evaluating dynamic drape properties of fabric when its static condition is disturbed. To find dynamic drape coefficient, we need to simulate body motion or the actual condition of use of fabric. Therefore, an instrument has been developed as reported in the last paper in this series. Here in this part the study conducted on dynamic drapeabilty of fabric in the newly developed instrument is reported.Key words: drape, static drape, dynamic drape, instrument, simulation Reference [1].

Application Of Optimisation Techniques In Aviation IndustriesAbstract: In the modern aircraft many components were produced because of the effort of engineering fraternity, most of the components were designed in a manner that they are subjected to various types of loads and stresses. In their life span members need to carry more amount of load but with a shorter thickness, designing them will induce curiosity among the engineers. There are many tools which are used practically for the design purpose and one such tool is optimization techniques. Design of engineering components is a costly process in which a small reduction in size wills ultimate lead to huge saving, many researchers and engineers focus on this area of called as optimization. To support optimization process many techniques were evolved in the recent decades some of them proved to be highly successful in optimizing and also widely used by many industries. Aviation industry one of the core engineering industry carries importance in designing and many design procedures were evolved in designing aircraft components which are not only costly to produce but also need utmost care in designing. Optimization plays a key role in design process let it be designing of a wing or landing gears, fuselage or rudders reducing the size for the load applied proves to be the only viable option for cost reduction.

177. | Minimizing Routing Attacks in MANET Using Extended Dempster-Shefer Theory
Minimizing Routing Attacks in MANET Using Extended Dempster-Shefer TheoryAbstract: Mobile Ad hoc Networks (MANET) have been highly vulnerable to attacks due to the dynamic nature of its network infrastructure. Among these attacks, routing attacks have received considerable attention since it could cause the most devastating damage to MANET. Even though there exist several intrusion response techniques to mitigate such critical attacks, existing solutions typically attempt to isolate malicious nodes based on binary or na¨ıve fuzzy response decisions. However, binary responses may result in the unexpected network partition, causing additional damages to the network infrastructure, and na¨ıve fuzzy responses could lead to uncertainty in countering routing attacks in MANET. In this paper, we propose a risk-aware response mechanism to systematically cope with the identified routing attacks. Our risk aware approach is based on an extended DempsterShafer mathematical theory of evidence introducing a notion of importance factors. In addition, our experiments demonstrate the effectiveness of our approach with the consideration of several performance metrics. Route request flooding attack is one such distributed DoS attack, launched by compromised nodes or intruders. This triggers an acute need of flooding attack prevention mechanisms for this highly vulnerable type of network. In this paper, a reputation based scheme is proposed to resist the impact of flooding attack in MANET. This scheme observes the behavior of a node in the network periodically and limits its route request sending rate accordingly.Index Terms: Mobile ad hoc networks, intrusion response, risk aware, dempster-shafer theory.

High Performance Error Detection and Correction Technique for Memories Using Difference - Set CodesAbstract: As technology scales, Single Event Upsets (SEU) become more common and affect a large number of memory cells. In order to protect memories against SEUs is to make use advanced error detecting and correcting codes are used. An error detection method for difference – set cyclic codes with majority logic is presented in this paper. Majority logic decodable codes have the capability to correct a large number of errors so these codes are used in memory applications. But they require a large decoding time which affects the memory performance. The proposed fault detection technique resolves this problem. It reduces the memory access time when there is no error in the data read. In this technique the Majority Logic Decoder (MLD) itself used to detect failures, thus area become minimal and keeps the extra power consumption low.Key words: Error Correcting Code, block codes, majority logic.

181. | Pattern Recognition Approach for Fault Identification in Power Transmission Lines
Pattern Recognition Approach for Fault Identification in Power Transmission LinesAbstract: This paper presents an improved algorithm for fault detection and classification of transmission line fault current signals using MATLAB/SIMULINK. The proposed algorithm presents a fault discrimination method based on the three-phase current and voltage waveforms measured when fault events occur in the power transmission-line network. The algorithm for fault classification employs wavelet multi resolution analysis (MRA) to overcome the difficulties associated with conventional voltage and current based measurements due to effect of factors such as fault inception angle, fault impedance and fault distance. The proposed algorithm for fault location, different from conventional algorithms that are based on deterministic computations on a well-defined model to be protected, employs wavelet transform. The wavelet transform captures the dynamic characteristics of the non-stationary transient fault signals using wavelet MRA coefficients.Index Terms: Wavelet transforms Multi resolution analysis (MRA), Fault classification, Transmission lines Reference [1].

Analysis of Power Semiconductor Device to Regulate the Load Voltage Using Dynamic Voltage Restorer (Dvr)Abstract: This paper deals with simulation and implementation of three level inverter based Dynamic Voltage Restorer (DVR). The control of DVR that injects a voltage in series with a distribution feeder is presented. DVR is a power electronic controller that can protect sensitive loads from disturbances in supply system. DVR can regulate the voltage at the load. The design issues, implementation procedures and system analysis for a fast transient control scheme for three phase capacitor-supported dynamic voltage restorers (DVR) are presented in this paper. The dynamic behaviors of the prototype under different sagged and swelled conditions and depths will be investigated. The dynamic voltage restorer (DVR) is one of the modern devices used in distribution systems to protect consumers against sudden changes in voltage magnitude. The analysis for a fast transient control scheme for three phase capacitor-supported dynamic voltage restorer (DVR) is presented in this paper. This work provides us to find the optimal location and the optimal DVR settings to enhance the distribution related loading issues. Conventional voltage-restoration technique is based on injecting voltage being in-phase with the supply voltage. The injected voltage magnitude will be the minimum, but the energy injected by the DVR is no minimal. In order to minimize the required capacity of the dc source, a minimum energy injection concept is taken into the considerations. It is based on maximizing the active power delivered by the supply mains and the reactive power handled by the DVR during the sag and swell cases. The review model has been built and tested the dynamic behaviors of the model under different sagged and swelled conditions and depths will be investigated. The quality of the load voltage under unbalanced and distorted phase voltages, and nonlinear inductive load is analyzed.Reference [1] Olimpo Anaya-Lara and E.

Corrosion Monitoring Of Reinforcement in Underground Galleries of Hydro Electric ProjectAbstract: The hydro projects in Himalayan region in India are constructed in head reaches of river basins. These projects envisage a concrete or masonry or rockfill or even an earthen dam. The underground inspection galleries and drainage gallery of these dams are constructed using concrete linings of different grades. Its durability is determined by various factors viz. aggressivity of surrounding water, temperatures fluctuations etc. The water in Himalayan Rivers is generally soft which is injurious to the useful life of concrete structures as it leads to leaching of lime. Leaching is a phenomenon that is caused by water migrating through the permeable concrete. The reduced alkalinity and permeated water causes corrosion of reinforcement leading to weakening of structure. Once such phenomenon is observed in any such structures a vigilant periodic monitoring approach becomes mandatory. The suitable remedial measure to be adopted will depend on the observed degree of deterioration. In this paper effort has been made to assess degree of corrosion of reinforcement in the gallery of one of the projects in Himalayan region using Half Cell Potentiometer which is a technique, used for assessment of the durability of reinforced concrete and helps in diagnosing reinforcement corrosionKey words: Corrosion, galleries, half cell potentiometer, reinforcement, rebar.

Hybrid Technology Solar Thermal Membrane Desalination of Salt Water for Populations In The Saloum River DeltaAbstract: The use of brackish water in the Saloum Delta in Senegal can be made by combining the processes of desalination as a source of solar energy, usually thermal and photovoltaic processes for membrane distillation. But the demand for energy is growing; the use of solar energy can be a good solution, given the high solar potential in these areas. Different experiences around the world have shown that the process AGMD (Air Gap Membrane Distillation) is properly adapted to renewable energy. Our work has shown that the production of fresh water by a hybrid method of desalination is possible. Then we analyzed the results on the effect of the pore size of the membrane on the mechanisms of mass transfer to estimate the production of fresh water per day generated. We also showed the effect of hot water heated by a solar panel on the phenomena of polarization membrane solution. And the final result allowed us to estimate in a dynamic system and for a small model, a daily production of about 4 L / h.Key words: Solar-Desalination-Membrane distillation - production flow-dynamic system-hybrid method–brackish water Reference [1] ALKLAIBI.

Determination of Hyper Static Moments in Post-Tensioned Concrete Flat SlabAbstract: Hyperstatic forces develop in an indeterminate structure. These forces result when the imposed deformations due to prestressing are restrained or prevented by the support conditions of the structure. The presence of these secondary moments involves extra work in the analysis and design of statically indeterminate prestressed concrete structures. A parametric study has been presented in this paper where three flat slabs of different aspect ratios have been analysed. Based on the observations of this study further problem has been defined. In this paper, a 3x3 panel flat slab of size 7.2mx5.76m has been selected for the analysis. The ultimate moments due to dead load and live load are balanced totally by cables. Percentage hyperstatic moments developed in comparison to primary moments in all strips are computed. Further balancing of moments to a selected range of 50%, 60% and 70% has been made. The compressive stress check of all the models at transfer and service stage has been made.Key words: Hyperstatic moments, post-tensioned flat slab, concordant profile Reference [1] IS:1343-1980 Indian Standard Code of Practice For Prestressed Concrete.

AABS Technique for Detection of Moving ObjectsAbstract: Image and Video Processing has a wide range of applications among various communities. Real Time moving object detection has become an important task in the Image and Video processing applications like robotics and video surveillance systems. There are various techniques in order to detect moving objects. In this paper we bring forward a hardware and software implementation of detection of moving objects using Background Subtraction technique. And we also bring forward the details of the moving objects which are detected, by using the Image reconstruction. For this purpose the following steps are executed – 1) A background image is stored in the SRAM Memory. 2) Low-pass filter is applied to both background image and the foreground images. 3) Foreground images are subtracted from the background image in order to identify the moving object. 4) Image processing techniques are applied to identify the moving object. 5) Image reconstruction techniques are used to obtain the details of the moving object. Interfacer is used either to store the resultant images in the memory or to display them on the screen.Key words: Background Subtraction Technique, Moving Object Details, Moving Object Detection, RGB to Gray Scale, Shadow Removal Technique Reference [1].

191. | Human Re-Identification In Surveillance Network
Human Re-Identification In Surveillance NetworkAbstract: This paper presents an appearance-based model to address the human re-identification problem. Human re-identification is an important and still unsolved task in computer vision. Re-identification refers to the problem of establishing correspondence among various observations of the same subject viewed at different time instances in different camera positions. It can also be defined as the process to match persons observed in non overlapping camera views with visual features for inter-camera tracking. The ambiguity increases with the number of candidates to be distinguished. Simple temporal reasoning can simplify the problem by pruning the candidate set to be matched. In many systems there is a requirement to identify individuals or determine whether a given individual has already appeared over a network of cameras. The human appearance obtained in one camera is usually different from the ones obtained in another camera. In order to re-identify people a human signature should handle difference in illumination pose and camera parameters. The paper focuses on a new appearance model based on Mean Riemannian Covariance (MRC) patches extracted from tracks of a particular individual to capturing from a distance even at low resolution without active co-operation of subjects, has motivated us to use it for re-identification in the computer surveillance network.Key words: Re-identification, Riemannian manifold, Human detection, Gait, Phase of motion Reference [1] Rabiner, L.R., 1989.

Enhanced New Improvement Algorithm in WSN with Efficient Transmission for Energy-SavingAbstract: The Coverage problem is very eminent and tough to maintain in WSN. This paper firstly finds out redundant nodes using classical Coverage Preserving Nodes Scheduling Scheme (CPNSS) algorithm and Sponsor Sector Based Off-duty Eligibility Rule of the WSN. We propose an Enhanced New Improvement Algorithm (ENIA) which focuses on the problem of CPNSS low efficiency and energy unbalance and save the extensive amount of energy of network. Here sensor nodes are grouped to form several independent sets and each set can cover all the area of the WSN. The Set having the largest average energy becomes the working node of particular portion of an area. Based on both residual energy and distance to base station, a Main M-working-Set is chosen among all working-sets. So, The Sets having the largest energy residual and minimum distance will communicate to base station without involvement of other working sets. Therefore this leads to energy-saving, congestion-control and reduced overhead at base station.Key words: WSN; Coverage; Redundancy; Energy-balance; Average energy; Distance Reference [1] Yang Tao, Lian-yong Yuan, Ya-li Wang.

193. | Interphase Slipping Effect on Flame Propagation Characteristics in Micro-Iron Dust Particles
Interphase Slipping Effect on Flame Propagation Characteristics in Micro-Iron Dust ParticlesAbstract: In this paper, the impact of interphase slipping (i.e., relative velocity between micro-iron dust particles suspended in air and surrounding gas flow) on flame propagation characteristics is studied. Initially, to obtain an explicit algebraic equation for the flame velocity, mass and energy conservation equations are solved. Then, dynamic equations of micro-iron particles during the upward flame propagation in a vertical duct are considered to calculate the particle velocities as a function of their distances from the leading edge of the flame. After that, by balancing the mass flux passing through a control volume above the leading edge of the flame, the change in the number density of the particles is determined. As a result, it is shown that due to the interphase slipping effect, mass concentration of micro-iron particles upon the leading edge of the flame is approximately twice as large as it at a distance far from the flame. This accumulation causes flame moves in a denser dust cloud, which has a significant effect on the flame propagation characteristics such as flame velocity and temperature. The theoretical results show reasonable correlation with the experimental data.Key words: Micro-iron particles; Interphase slipping; Flame velocity; Mass concentration; Heterogeneous combustion Reference [1] G.

Enhancement of Power Quality in Distribution System with Reduced DSTATCOM Voltage RatingAbstract: In power distribution network, distribution static compensator (DSTATCOM) is used for enhancing power quality. This paper investigates the application of DSTATCOM with non-stiff source connected to distribution network to enhance power quality. The model discussed in this paper is designed to have reduced DC-link voltage rating without compromising compensation capability when non-linear loads are connected to distribution network. This model uses a series capacitor along with interfacing inductor and a shunt filter capacitor. Having this reduced DC-link voltage, the average switching frequency of insulated gate bipolar transistor (IGBT) switches of DSTATCOM reduces and thus reducing switching losses in inverter. Simulation studies are carried out using matlab/simulink and the results shown proves the performance of the system when non-linear loads are connected.Key words: DSTATCOM, DC-link voltage, non-linear loads, non-stiff source, power quality.

195. | Effect Of Sulphate Attack On Strength Characteristic Of Fiber Reinforced High Volume Fly Ash Concrete
Effect Of Sulphate Attack On Strength Characteristic Of Fiber Reinforced High Volume Fly Ash ConcreteAbstract: The production of fly ash increases with the coal utilisation and contributes to environmental degradation. The dumping problem of fly ash raised the alarming situation in the world which initiated towards consumption of fly ash in industry. The road construction industry is one which consumes the cement for its pavement and other structures. The pavement will fail mostly due to excessive tensile stress. The use of plain high volume fly ash concrete suffers from low tensile strength and limited ductility. These problems can be eliminated by introducing the reinforcement. When the fibers are mixed with concrete the tensile property of concrete increases. There were numerous studies on the strength characteristic of concrete containing fly ash. However, there is little study in the literature regarding the strength of HVFA concrete with fibers subjected to sulphate media. Thus the aim of this work is to study the effect of variation of fiber content from 0.2% to 1.8% in high volume fly ash concrete exposed to sulphate media. It is also aimed to study the effect of fibers on HVFAC subjected to sulphate attack for different periods. The studies cited in this paper, regarding sulphate attack on fiber reinforced high volume fly ash concrete, are presented the strength characteristics up to 90 days of exposer condition. In this research work locally available materials are used. The fly ash is obtained from Raichur thermal power plant. Crimped steel fibers are used. The design of HVFAC mix was carried out as per the guidelines of CANMET hand book [1]. The study reveals the fact that the strength characteristics of fiber reinforced high volume fly ash concrete (FRHVFAC) attain higher value at 1.4% additions of steel fibers, when subjected to sulphate attack.Key words: Fly ash, HVFAC, FRHVFAC, Pavement, Compressive strength, Tensile strength.

Mathematical Modeling as a Novel View for Advanced Research in Ground WaterAbstract: Water pollution has been a crucial problem in many countries and has attracted researcher's attention from all over the world. The variations in selected physico-chemical factors were investigated for twelve sampling stations to determine the water quality of Batlagundu, Dindigul District, Tamilnadu for drinking and other domestic activities. The samples have been analyzed to determine 24 physico chemical parameters. The parameters namely temperature, turbidity, pH, sulphate, potassium, phosphate, Dissolved Oxygen, Biochemical Oxygen Demand and Chemical Oxygen Demand were within the permissible limits of BIS and WHO while other parameters such as total dissolved solids, electrical conductivity, total hardness, total alkalinity, calcium, magnesium, chloride, nitrate, nitrite, fluoride, sodium and iron were found to exceed the limit. This paper proposed a mathematical model to predict the effect of various physico-chemical parameters present in ground water.

FPGA Based Implementation for Ripple Carry Adder with Reduced Area and Low Power ConsumptionAbstract: A multiplier is one of the key hardware blocks in most digital and high performance systems such as FIR filters, digital signal processors and microprocessors etc. With advances in technology, many researchers have tried and are trying to design multipliers which offer either of the following- high speed, low power consumption, regularity of layout and hence less area or even combination of them in multiplier. However area and speed are two conflicting constraints. So improving speed results always in larger areas. So here we try to find out the best trade off solution among the both of them. While comparing the adders we found out that Ripple Carry Adder had a smaller area while having lesser speed, in contrast to which Carry Select Adders are high speed but possess a larger area. And a Carry Look Ahead Adder is in between the spectrum having a proper tradeoff between time and area complexities.Key words: Ripple Carry Adder, Carry Select Adder, Carry Skip Adder, Carry Look Head Adder FIR Filter.

Network and Generator Constrained Economic Dispatch Using Real and Binary Coded Genetic AlgorithmsAbstract: The efficient and optimum economic operations of electric power generation systems have always occupied an important position in the electric power industry. This involves allocation of the total load between the available generating units in such a way that the total cost of operation is kept at a minimum. Network constrained economic dispatch have been applied to obtain optimal fuel cost while satisfying transmission line power flow limits. Similarly generator constrained economic dispatch schedules the outputs of generating units to meet the demand at minimum cost considering the prohibited zones. This paper proposes different types of Genetic Algorithms such as Binary Coded GA, Real Coded GA and Directional Search GA for solving the classical economic dispatch problem. The purpose of Network Constrained Economic Dispatch (NC-ED) and Generator Constrained Economic Dispatch is to minimize the operating fuel cost while satisfying load demand and operational constraints. As such, a Heuristic Algorithm is developed in this paper to adjust the generation output of a unit in order to avoid unit operation in the prohibited zones.Key words: Economic Load Dispatch, Genetic Algorithm, Heuristic Algorithm, Network Constraints Reference [1] Ioannis G.Damousis, Anastasios G.

This seemingly obvious point, frequently bypassed in general analysis, cannot be overlooked in the field of power line communications. The conditions required for superposition to be applicable (i.e., linearity and time invariance) are not met for the majority of power line networks. In this project, current meter reading along with appliance information will be sent to RFID and power cables.

Low Power, High Speed Parallel Architecture For Cyclic Convolution Based On Fermat Number Transform (FNT)Abstract: The power consumption, Delay and Area of this new novel 4-2 Compressor Architecture is compared with Existing architecture. In the proposed architecture the outputs are efficiently used to improve Low power, high speed, performance, less and delay. FNT is exact with no round off errors and Truncation errors. The Binary Arithmetic in FNT performs the Exact Computation. To perform the cyclic convolution in FNT some techniques are implemented. The Techniques are code Conversion method without Addition (CCWA) and Butterfly Operation without Addition (BOWA) are proposed to perform the FNT and its Inverse (IFNT) except their final stages in the Convolution. Here the Point wise Multiplication in the Convolution is accomplished by Modulo 2^n+1 Partial Products Multipliers (MPPM) and Output partial products which are Inputs to the IFNT. Thus Modulo 2^n+1 Carry save Propagation Additions are avoided in the FNT and the IFNT except their final stages and the Modulo 2^n+1 multiplier. Thus the Power and Execution delay of the entire FNT will be reduced which is only because of usage of above techniques in the Design. Therefore the proposed one has less Power better Throughput Performance and involves less hardware complexity. This will be done by using Very Large Scale Integration (VLSI) technology and various Cad tools available, so as to implement hardware The synthesis results using 180nm SOC Technology is been used.Reference [1] J.

204. | Quality Inspection and Grading Of Mangoes by Computer Vision & Image Analysis
Quality Inspection and Grading Of Mangoes by Computer Vision & Image AnalysisAbstract: The paper presents the recent development and application of image analysis and computer vision system in quality evaluation of products in the field of agricultural and food. It is very much essential to through light on basic concepts and technologies associated with computer vision system, a tool used in image analysis and automated sorting and grading is highlighted. In agricultural industry the efficiency and the proper grading process is very important to increase the productivity. Currently, the agriculture industry has a better improvement, particularly in terms of grading of fruits, but the process is needed to be upgraded. This is because the grading of the fruit is vital to improve the quality of fruits. Indirectly, high quality fruits can be exported to other countries and generates a good income. Mango is the third most important fruit product next to pineapple and banana in term of value and volume of production. There are demands for this fresh fruit from both local and foreign market. However, mangoes grading by humans in agricultural setting are inefficient, labor intensive and prone to errors. Automated grading system not only speeds up the time of the process but also minimize error. Therefore, there is a need for an efficient mango grading method to be developed. In this study, we proposed and implement methodologies and algorithms that utilize digital image processing, content predicated analysis, and statistical analysis to determine the grade of local mango production. Computer vision provides one alternative for an automated, non-destructive and cost-effective technique to accomplish these requirements. This inspection approach based on image analysis and processing has found a variety of different applications in the food industry.Key words: Agricultural and Food Products, Computer vision, , Fruit ,Grading and Sorting, Image analysis and Processing , Machine Vision, Mango grading, Online inspection, Quality,.

Detecting Sudden Pedestrian Crossings and Avoiding Accidents Using Arm 11Abstract: We are aware of the problem of detecting sudden pedestrian crossings to assist drivers in avoiding accidents. We design embedded system, the application has two major requirements: to detect crossing pedestrians as early as possible just as they enter the view of the car-mounted camera and to maintain alarm system to alert the Driver. Our Embedded system using ARM 32 bit Microcontroller has feature of image/video processing by using various features and classification algorithms have been proposed for pedestrian detection. It overcomes the performance in terms of sensors and hardware cost is also too high. So, our design Embedded system that detects partially visible pedestrians just as they enter the camera view, with low false alarm rate and high speed. This system takes capture image by means of web camera connected to ARM microcontroller through USB and the image is processed by using image processing technique. When any pedestrian is detected it alerts driver by providing alarm sound and also it stops vehicle automatically. The display unit in vehicle provides clear details at position it detects pedestrian either right or left.Key words: S3C6410 controller, USB device, USB camera and stepper motor Reference [1] K.

Enhancement of the Performance of Vector Controlled Back-to-Back VSC System under Grid DisturbancesAbstract: The increasing emergence of VSC-based transmission is the result of development in semiconductor devices, power electronic circuits, control, and executive engineering, The most important limiting factor of power semiconductors is their switching properties since they are usually optimized for the conduction intervals. This concept specifically proposes a control structure to improve the performance of high-power vector-controlled back-to-back VSC systems for wind generators and for transmission systems applications. The main improvement is to suppress the possible dc-link voltage fluctuations under power line faults and unbalanced conditions. The proposed controller structure is designed based on regulating the converter system's states locally in d-q synchronous reference frame without sequence components extraction or resonant notch compensator. The mat lab results verify the validity of the proposed control architecture during normal and unbalanced power system conditions.Index terms: Vector controlled, VSC, Wind, Recovery transformer,Matlab Reference [1] A.

208. | Congestion Control Load Balancing Techniques in MANET: A Survey
Congestion Control Load Balancing Techniques in MANET: A SurveyAbstract: In Mobile Ad hoc Network (MANET), there is no pre-existing communication infrastructure (no access points, no base stations) and the nodes can freely move and self-organize into a network topology. Such a network can contain two or more nodes. Hence, balancing the load in a MANET is important because the nodes in MANET have limited communication resources such as bandwidth, buffer space and battery power. Scalability is of particular interest to ad hoc network designers and users and is an issue with critical influence on capability and capacity. Where topologies include large numbers of nodes, routing packets will demand a large percentage of the limited wireless bandwidth and this is exaggerated and exacerbated by the mobility feature often resulting in a high frequency of failure regarding wireless links. In this paper we present a inclusive survey and categorization of recently published congestion handling and load sharing multipath techniques. These surveys focus on various load metrics and various load balancing routing protocols for efficient data transmission in MANET.Index Terms: Survey, Load balancing, Mobile Ad hoc networks, routing, multipath.

As fourth generation wireless mobile communications, WiMAX provides group of users with a connection and a queue of fixed length. Performance of such wireless technology is analyzed using SIMO, MIMO, Markov arrival process (MAP) and so on. In this paper a probability transition matrix is used to evaluate performance of network and two Connection Admission Control (CAC) schemes have been proposed to ensure Quality of Service (QoS). Finally, blocking probability due to proposed CAC has been measured to evaluate proposed scheme.

The proposed scheme is a FPGA implementation of Park-Miller algorithm for generating sequence of Pseudo-Random keys. The generated pseudo random sequences are comparatively less complex in computation, power efficient and flexible so that it makes the digital circuit faster and smaller. The operation of Park-Miller algorithm to generate pseudo random number uses 32-bit Booth multiplier for multiplication, 32-bit floating point divider for division and a finite state machine for the flow of Park-Miller algorithm operation. After generating a sequence of 32-bit pseudo-random numbers, it is used as a key to encrypt the text message which is known as cipher text. Using the same key to decrypt the encrypted data to get back original text message. The programming is done in Verilog-HDL and MATLAB to verify the result. The design is simulated in Modelsim (version 10.5). The proposed module is successfully synthesized using Cadence RTL compiler. Area and power of the design is computed for 180nm technology. Finally design is implemented on Spartan 6E FPGA.Key words: Cryptography security, Encryption, Decryption, Park-Miller Algorithm, Pseudo random bit generator Reference [1] Z.G.

212. | A Novel Approach Of Performance Analysis Of A Novel ICI Through ICI Self-Cancellation-Scheme In OFDM Systems Using BER
A Novel Approach Of Performance Analysis Of A Novel ICI Through ICI Self-Cancellation-Scheme In OFDM Systems Using BERAbstract: OFDM is a multicarrier modulation technique in which a high rate bit stream is split into N parallel bit-streams of lower rate and each of these are modulated using one of N orthogonal sub-carriers. In a basic communication system, the date is modulated onto a single carrier frequency. The available bandwidth is then totally occupied by each symbol. This kind of system can lead to inter-symbol-interference (ISI) in case of frequency selective channel. The basic idea of OFDM is to divide the available spectrum into several orthogonal sub channels so that each narrowband sub channels experiences almost flat fading. Orthogonal frequency division multiplexing (OFDM) is becoming the chosen modulation technique for wireless communications. A well-known problem of OFDM is its sensitivity to frequency offset between the transmitted and received signals, which may be caused by Doppler shift in the channel, or by the difference between the transmitter and receiver local oscillator frequencies. This carrier frequency offset causes loss of orthogonality between sub-carriers and the signals transmitted on each carrier are not independent of each other. The orthogonality of the carriers is no longer maintained, which results in inter-carrier interference (ICI). The undesired ICI degrades the performance of the system. This paper investigates an efficient ICI cancellation method termed ICI self-cancellation scheme for combating the impact of ICI on OFDM systems.Key words: Inter carrier interference, orthogonality, Doppler shift, Self-cancellation, BER etc.., QPSK, QOSTBC (Quasi-Orthogonal Space-Time Block Code) Reference [1] Z.Yuping and S.-G.

214. | A Novel Approach for Reduction of Poisson Noise in Digital Images
A Novel Approach for Reduction of Poisson Noise in Digital ImagesAbstract: An image is often corrupted by noise in its acquisition and transmission by various kinds of noises. Image denoising using thresholding methods means find appropriate value (threshold)which separates noise values to actual image values without affecting the significant features of the image.Wavelet transform represents image energy in compact form and representation helps in determining threshold between noisy features and important image feature. This paper is organized as follows: First poison noise is removed by median filter; and then removed by wiener filter, second noisy image is denoised with the help of wavelet based techniques using thresholding, third thresholding is applied on the result of first and second simultaneously for image denoising and fourth PSNR (Peak Signal To Noise Ratio), MSE (Mean Square Error) calculated and results are compared in all cases. The aim of this paper is to identify the best poison noise removal filter from the comparative study analysis of filtering methods and wavelet based thresholding technique. The best filter is estimated by calculating Peak Signal Noise Ratio (PSNR) and Means Square Error (MSE).Key words: Image denoising, PSNR, MSE, Median filter, Wiener filter, Thresholding, Wavelet Transform.

Aqua Plant -Based Sewage Treatment Plants: ReviewAbstract: These studies present a general perspective of the field with most known examples from common literature, emphasizing a practical point of view in this technologically oriented topic. Conventional wastewater treatment plants as major contributors to greenhouse gases. Duckweed, Algae and Fish culture based wastewater treatment also releases CO2 but the algae consume more CO2 while growing than that is being released by the plant, this makes the entire system carbon negative .Algae-based wastewater treatment technology is suited for tropical countries where the temperature is warmer and sunlight is optimum. Environmental factors play a major role in algae cultivation. Maintenance of optimum temperature and lighting in algae ponds are difficult. Apart from these environmental factors, there are a number of biological problems and operational problems can arise in the mass cultivation of microalgae using wastewater. These include contamination and grazing. Control measures for avoiding contamination by bacteria and other algal species are sterilization and ultra-filtration of the culture medium.Key words: FACTS system stability, three phase fault.

Comparative Study of Various Impulse Noise Reduction TechniquesAbstract: Removal of noise is an essential and challengeable operation in image processing. Before performing any process, images must be first restored. Images may be corrupted by noise during image acquisition and transmission. Noise and blurring effects always corrupts any recorded image. To reduce the impulse noise level in digital images various filters were introduced amongst we have presented a concise overview of the most useful restoration filters. In this paper we have presented the study and comparison of filtering techniques for the detection and filtering of impulse noise from the gray scale images. Performance of Non fuzzy filters i.e. classical filters and the fuzzy filters are analyzed based on various image quality assessment parameters.Reference [1] Kh.

Effects of Silica Fume in Conventional ConcreteAbstract: The production of tailor made high strength and high performance concrete are made by incorporating silica fume into the normal concrete and it is a routine one in the present days. The mix proportioning is intricate and the design parameters are increased due to the incorporation of silica fume in conventional concrete. The aim of this paper is to look into the different mechanical properties like compressive strength, compacting factor, slump of concrete incorporating silica fume. In this present paper concrete incorporating silica fume are cast for 5 (five) mixes to perform experiments. Different percentages of silica fume are used for cement replacement in order to carry out these experiments at a single fixed water-cementitious materials ratio keeping other mix design parameters constant. The cement replacement level by silica fume was 0%, 5%, 10%, 15% and 20% for a constant water-cementitious materials (w/cm) ratio for 0.50. 100 and 150 mm cubes are used to determine the compressive strengths for all mixes at the age levels of 24 hours, 7 and 28 days. Besides the compressive strengths other properties like compacting factor, slump of concrete are also determined for five mixes of concrete.Key words: Silica fume, High strength concrete, High performance concrete, Strength.

Implementation of Haar Wavelet through Lifting For DenoisingAbstract: Techniques based on Haar wavelet through lifting coefficients are gaining popularities for denoising data. The idea is to transform the data in to the wavelet basis, where large magnitude wavelet coefficients are mainly the signals and the smaller magnitude coefficients represents the noise. By suitably modifying these coefficients, the noise can be removed from data .wavelet denoising is problem on implementation on computer is somewhat difficult. In order to implement on computer we will use Haar wavelet through lifting for denoisingReference [1] D.L. Donoho and I.M.

Control of Power at Weak-Grid Using UpqcAbstract: In this paper a compensation strategy based on a particular CUPS device, the Unified Power Quality Compensator (UPQC) has been proposed. A customized internal control scheme of the UPQC device was developed to regulate the voltage in the WF terminals, and to mitigate voltage fluctuations at grid side. The voltage regulation at WF terminal is conducted using the UPQC series converter, by voltage injection "in phase" with PCC voltage. On the other hand, the shunt converter is used to filter the WF generated power to prevent voltage fluctuations, requiring active and reactive power handling capability. The sharing of active power between converters, is managed through the common DC link. Therefore the internal control strategy is based on the management of active and reactive power in the series and shunt converters of the UPQC, and the exchange of power between converters through UPQC DC–Link.Index terms: windfarm, weakgrid, upqc, induction generator, cups.

226. | WSNs BASED NETWORK DENSITY ON THE OPTIMAL NUMBER OF CLUSTER USING ARM PROCESSOR
WSNs BASED NETWORK DENSITY ON THE OPTIMAL NUMBER OF CLUSTER USING ARM PROCESSORAbstract: A wireless sensor network (WSN) consists of spatially distributed autonomous sensors to monitor physicalor environmental conditions, suchas temperature, sound, pressure, PIR etc. and to cooperatively pass their data through the network to a main location. The development of wireless sensor networks was motivated by military applications such as battlefield surveillance; today such networks are used in many industrial and consumer applications, such as industrial process monitoring and control, machine health monitoring, and so on. The WSN is built of "nodes" from a few to several hundreds or even thousands, where each node is connected to one (or sometimes several) sensors. Each such sensor network node has typically several parts: a radio transceiver with an internal antenna or connection to an external antenna, a microcontroller, an electronic circuit for interfacing with the sensors and an energy source, usually a battery or an embedded form of energy harvesting. A sensor node might vary in size from that of a shoebox down to the size of a grain of dust, although functioning "motes" of genuine microscopic dimensions have yet to be created. The cost of sensor nodes is similarly variable, ranging from a few to hundreds of dollars, depending on the complexity of the individual sensor nodes. Size and cost constraints on sensor nodes result in corresponding constraints on resources such as energy, memory, computational speed and communications bandwidth. The topology of the WSNs can vary from a simple star network to an advanced multi-hop wireless mesh network. The propagation technique between the hops of the network can be routing or flooding.Key words: Zigbee ; wireless sensor network; routing; sensors; clustering; ARM7 processor Reference [1] I.Mahgoub and M.

227. | An Approach towards Repairing Of Nimonic Alloy Component through Laser Based Layered Manufacturing Technique
An Approach towards Repairing Of Nimonic Alloy Component through Laser Based Layered Manufacturing TechniqueAbstract: In this work investigate has been done to identify the possibility of depositing a layer of Ni-Co-Cr powder mixture over an experimental block of Nimonic 263 alloy material in order to repair it by a 2 kW Ytterbium fiber laser. The various process parameters have been optimized to obtain the best quality deposition free of porosity and cracks. An optical microscopic study of the resulting microstructures of the substrate and deposited layers has been conducted. For further study SEM, analysis have also been carried out. The microhardness of deposited layer ranged from HV0.05306 to HV0.05331. The hardness decreases gradually from the top of the deposited layer to the substrate zone. The knowledge achieved in this study would help in taking decisions with regard to setting the parameters required for subsequent repair a Nimonic component through layered manufacturing.Key words: Laser, Direct Metal Laser Sintering, Nimonic 263, Repair Reference [1] J.

Privacy of Integrated Data Using Efficient Classification AlgorithmAbstract: Data mining is a field where analysis on the basis of certain parameters can be analyzed. During the process of data mining dataset plays an important role on the basis of which analyses can be fulfilled. But during the processing of the dataset security is also important issue, since the chances of data leak or attacks have increased. Hence privacy preservation is important for the security of these datasets. Here in this paper an efficient implementation of privacy preservation of data using horizontal partition id3 classification tree is proposed which can used as an application for the data integration services. Here data can be collected from different sources which can be integrated at the UTP and privacy of this data can be preserved using our proposed algorithm.Key words: privacy preservation, integration, PPDM, Anonymity, UTP, classification, decision tree.

240. | Detection of Errors on Serial Communication Lines in RTOS Based-Embedded Systems
Detection of Errors on Serial Communication Lines in RTOS Based-Embedded SystemsAbstract: Embedded Real Time application uses multi threading, a key concept of any conventional OS. The advantage of multi-threading include greater throughput, more efficient use of CPU such that it cannot remain idle for long time, better system reliability, improved performance on multiprocessor computer. The use of Real Time Operating Systems (RTOSs) became an attractive solution to simplify the design of safety-critical real-time embedded systems. Due to their demanding strict attention to rules and procedures constraints such as high-speed, low voltage operation and battery-power dependence, because of sudden up and down of voltages, transients in flow of current can cause error in serial communication lines. External conditions, such as Electromagnetic Interference (EMI), Heavy-Ion Radiation (HIR) as well as Power Supply Disturbances (PSD) can also cause transient faults. As the major consequence, the system's reliability degrades. In this paper, the main focus will be on the detection of the errors on the serial communication lines. This is achieved by using a hardware approach with the combination of Cyclic Redundancy Check and RTOS. During execution of these programs, the proposed system exposed to EMI according to the international standard for voltage transients, voltage dips and short interruptions on the serial communication lines of electronic systems. The obtained result shows that the proposed approach is able to provide higher fault coverage.Key words: Hardware-Based Approach, Real-Time Operating System, Reliable Embedded System, Electromagnetic Interference (EMI), Serial Communication lines, Cyclic Check Redundancy (CRC).

Multilevel inverters can operate not only with PWM techniques but also with amplitude modulation will improves significantly the quality of the output voltage waveform. With the use of amplitude modulation, low frequency voltage harmonics are perfectly eliminated. This paper presents a single-phase 81-level Hybrid multilevel inverter for a grid-connected system which is used for reactive power compensation. The proposed topology has the feature like boost output voltage capability along with capacitor voltage balancing. Simulation results obtained from Matlab/Simulink to simulate 81-levels of voltage with only four power supplies and sixteen transistors.Key words: Amplitude Modulation Technique, Capacitor voltage balancing capability, Matlab/Simulink, Reduction of switches, Voltage boosting capability.

Analysis and Assessment of Flow and Strength Behaviour of Clsm with Lyse and Abram's Rule as BasisAbstract: Strength and workability is the main factor in the cement mortar and concrete. These are Controlled Low Strength Materials (CLSM) with required flow characteristics such as self-leveling ability, free from settlement after hardening with potential to develop low strength in the range of 1 to 10 MPa. Presently the use of CLSM in practice is ahead of development of appropriate technology to handle a very wide spectrum of practical needs of flow characteristics and to handle combinations with a wide spectrum of materials. In this investigation it is attempted to develop a phenomenologieal model within the basic framework of Lyse Rule and Abram's Rule, already explored in concrete technology. The basic tenet of this law is that the basic property of present mix is in a particulate state similar to saturated clays. In this fresh state, shearing resistance of the mix is a function of total water content similar to saturated clays. Spread flow test on mixes with low cement content and high volume fly ash and GGBFS combinations with Quarry Dust as fine aggregate as well as with only cement and fly ash pastes are conducted. Thus generated data is analyzed to advance a phenomenological model. The validity or this model is verified with an independent set of data generated for this purposeKey words: Controlled Low Strength Materials (CLSM): Lyse Rule: Spread Flow Test Abram's Rule : Strength test on Phenomenological Model Reference [1] ACI Committee 229 (1994) "Controlled Low Strength Materials" (CLSM) (ACI 229R-94) American Concrete Institute.

247. | Preserving Interflow Packet Order in Multipath Switching Systems Using Flow-Based Slicing For Congestion Avoidence
Preserving Interflow Packet Order in Multipath Switching Systems Using Flow-Based Slicing For Congestion AvoidenceAbstract: Congestion avoidance is an important traffic engineering task, which can be performed by making use of load- balancing technique when a link is over loaded or failure of link occur in Multi-Path Switching Systems . Multipath Switching Systems are capable of transferring high rate data in networks. As preserving the inter flow packet orders while avoiding congestion is a major issue in consideration and previous packet based solutions require packet reordering which cause delay penalties. In this paper we use a flow-based slicing scheme which slits each flow in to slices at every inter- flow interval larger than the slicing threshold and balances the load to a finer granularity. We depict that flow-based slicing achieves inter flow packet ordering with little network cost while minimizing the packet out of order probability to negligible level comparatively less than 10-6.Key words: Congestion Avoidence, Flow-Based Slicing(FBS), Interflow Packet Ordering, Multipath Switching Systems(MPS), Reference [1] GAGANA.

It may be used to uncover the structure and content of unknown text sets as well as to give new perspectives on familiar ones. The focus of this paper is to experimentally evaluate the quality of clusters obtained using partitional clustering algorithms that employ different clustering schemes.

250. | Sage Package for Symbolic Computation of Series Solution of Ordinary Differential Equations Sage Package for Symbolic Computation of Series Solution of Ordinary Differential EquationsAbstract: The ordinary linear differential equations with constant coefficients can be solved by the algebraic methods and the solutions are obtained by elementary functions called the fundamental solutions. Most of the differential equations met in mathematics, physics and engineering sciences remain out of this class. In such cases, it is natural to search the solutions in the form of infinite series. The power series method is a well known procedure to solve ODEs with variable coefficients. The resulting series can be used to analyze and visualize the nature of the solutions of ODE's for which direct calculation is difficult. Manually solving a series solution using power series method is tedious and time consuming. In this paper a special package using SAGE (an open source software) have been developed, which can calculate any number of coefficients with no restriction to obtain the series solutions of up to third order ODE at an ordinary point. Also the well known Legendre and Hermite polynomials of any order can be generated and visualized by the way getting series solutions, In addition, Frobenius method for finding series solution around regular singular point cases are discussed.Key words: Ordinary Differential Equations, Power Series Solutions, SAGE for Differential Equations Reference [1] Shepley L .

The equations governing the unsteady boundary layer fluid flow are constructed and non-dimensionalized. The non-dimensional equations are discretized using implicit finite difference method of Crank-Nicolson type. The results obtained are interpreted and discussed using graphs. The study is carried out for different Hartmann and Eckert number (Pr = 0.71 and 7.0). Heat transfer effects are studied by plotting the temperature profiles and local Nusselt number. It is observed that increase in Eckert number enables increase in temperature profile and subdues the local Nusselt number.Key words: MHD flow, stretching sheet, unsteady boundary layer flow, viscous dissipation Reference [1] H.

252. | Design Of Low Power Cmos High Performance True Single Phase Clock Dual Modulus Prescaler
Design Of Low Power Cmos High Performance True Single Phase Clock Dual Modulus PrescalerAbstract: Dual-modulus prescaler is a critical block in power conscious PLL design. By modifying the second branch in the TSPC DFF, two TSPC DFFs can be cascaded directly to provide multiple division ratios. Domino Logic D-flip-flop is used to improve operating speed of true single-phase clock (TSPC), which results Charge sharing, Glitches and Critical path Delay due to the logic gates for mode selection. In this work True Single Phase Clock (TSPC) based on Ratioed logic D flip-flop and Transmission Gates (TGs) is implemented in 0.18μm CMOS process. A Glitch elimination TSPC D-flip flop is used in the synchronous counter. TGs are used in the critical path and the control logic for mode selection. The power efficient TSPC design technique is applied to 3/4 and 15/16 prescalers, and their performances are compared with previous work.The power efficient dual modulus 3/4 and 15/16 prescalers are designed using Eldo Simulation tool in Mentor Graphics and its performance are compared. Simulation and measurement results show high-speed, low-power, low PDP and multiple division ratio capabilities of the power efficient technique with a frequency range of 0.5-3.125GHz. The improved speed, the power efficiency, and the flexibility will promote its wide deployment in Multi gigahertz range applications.Key words: Dual modulus, frequency divider, prescaler, true single-phase clocked (TSPC) logic.

253. | Consolidation Stress Effect On Strength Of Lime Stabilized Soil
Consolidation Stress Effect On Strength Of Lime Stabilized SoilAbstract: Improvement of soft soils by deep mixing is gaining popularity in many countries. The strength of stabilized soils is generally estimated by conducting unconfined compression test, whereas triaxial compression tests are used very rarely. Further the undrained strength of the stabilized soil is considered for design. The strength of stabilized soil is treated as being independent of stress. Triaxial tests have shown that the drained strength of stabilized soils is stress dependent in a similar way to that of natural soils. Hence, the stress dependency of the strength of stabilized soils should be considered in the design process for most soil and loading conditions. Hence in the present study an attempt is made to bring out the effect of consolidation stress on the strength of lime stabilized soil. The various laboratory test such as vane shear test, unconfined compressive strength test and Triaxial test were conducxred. In general the undrained cohesion and the angle of internal friction increases with increase in lime content and curing periods. However for a given lime content and curing period, the undrained cohesion increases with increase in consolidation stress and angle of internal friction decreases with increase in consolidation stress. Hence, it is important to consider the consolidation stress effects to arrive at the design strength parameters for stabilized soils.Key words: Lime, Shear strength, Consolidation stress, Triaxial test, Unconfined compressive strength Reference [1] Bell F.G "Stabilization and treatment of clay soils with lime" Part I, Ground Engineering, Vol.21, 1988,PP .10-15.

256. | An Efficient Edge Detection Approach Based On Pollination Based Optimization
An Efficient Edge Detection Approach Based On Pollination Based OptimizationAbstract: Edge detection of pictures is a vital task in computer vision and image processing. Edge detection is always study focus in the field of medical image processing and analysis. It is necessary step in medical image processing. Edge detection of noise free pictures is comparatively less complicated, however in most sensible cases the photographs area unit degraded by noise. Edges in photos provide low-level cues, which could be utilized in higher level processes, like object detection, recognition, and classification, furthermore as motion detection, image matching, and trailing. Edges and textures in image are typical samples of high-frequency information. High-pass filters deduct low-frequency image information and therefore enhance high-frequency information like edges. Many approaches to image interpretation measure supported edges. This paper proposed an enhanced edge detection using Pollination based optimization (PBO) algorithm. In this, The samples of medical images (MRI) with resolution 128×128 is given as input and output as edges of image is produced. All images are gray scaled and we converted all samples to same size (128×128). In this firstly add speckle noise then filter this image by using bilateral filter to make image noise free. A bilateral filter preserves sharp edges by systematically looping through each pixel and adjusting weights to the adjacent pixels accordingly. It extends the concept of Gaussian smoothing by weighting the filter coefficients with their corresponding relative pixel intensities. Then we use PBO for edge detection. PBO based edge detection is a new technique and it perform as well in medical field also and we used MRI images in our work.Key words: Edge Detection, Medical field, MRI images, PBO, Bilateral Filter.

258. | The Magnetization of Water Arising From a Magnetic-Field and Its Applications in Concrete Industry
The Magnetization of Water Arising From a Magnetic-Field and Its Applications in Concrete IndustryAbstract: The magnetization of water arising from a magnetic-field and its applications of magnetized water in concrete industry are investigated. In this study we introduce firstly that correct method of magnetization of water. In order to elucidate clearly its applications in the concrete industry we studies and inspect in detail the influences of magnetized water on the mechanical and optic properties of concrete, including mass density tensile strength, tensile strength, compressive strengths, deformation modulus and Poisson's ratio, shear strength of broken (cohesive force internal friction angle) as well as the infrared spectrum of absorption and fluorescence spectrum by different methods involving synthetic method including the ultrasonic and rebounded techniques as well as infrared and fluorescence spectra, respectively. The results obtained from these investigations indicate that the mass density tensile strength, tensile strength, compressive strengths, deformation modulus and Poisson's ratio of the concretes increase, but its cohesive force internal friction angle decrease as well as some new peaks in the concrete occur under influences of magnetized water relative to those of pure water. These show clearly that the magnetized water enhance the combined force among the molecules or corpuscles or components and lifts its mass density. Thus the changes of mechanical and optic properties of the concrete under influence of magnetized water.Key words: magnetic-field, magnetized water, concrete, mechanical properties optic feature Reference [1] Xie WenHui, Magnetized water and its application, Science Press, Beijing 1983, p34 [2] K.M.Joshi, P.V.Kamat, J.Indian Chem.

A Study on the Effect of Injection Pressures On the Performance and Emission Characteristics of C I Engine with Pongamia Pinnata Methyl Ester as FuelAbstract: Compression ignition engine is a popular prime mover in rural areas, particularly in the places where electrical power is not available. The rapid depletion of fossil fuel has stimulated worldwide efforts to produce alternative fuel to diesel fuel. Use of bio fuel as an alternative fuel can contribute significantly towards the twin problem of fuel crises. The fuel of bio origin may be the bio diesel obtained from edible or non edible vegetable oil through transesterification process. Most of the properties of bio diesel compare favourably with the characteristics required for diesel fuel. This fuel in the form of blend with diesel performs almost as well as neat diesel fuel with no engine modification. Pongamia pinnata (Honge oil) is non edible vegetable oil. Experiments were conducted on 10 HP single cylinders, four stroke, water cooled CI engine using honge oil methyl esters to study the engine performance and emission at different injection pressures of 180, 200 and 220 bar. Non edible honge oil bio diesel was tested for their use as substitute fuels for diesel engines. The results showed a better performance and reduced emission at an injection pressure of 200 bar.Key words: Honge Oil Methyl Ester; CI Engine; Injection Pressure, Performance and Emission Characteristics.

Renewable Power Generation Units through Micro Grid SystemAbstract: Micro-grid system is currently a conceptual solution to fulfill the commitment of reliable power delivery for future power systems. Renewable power sources such as wind and hydro offer the best potential for emission free power for future micro-grid systems. This paper presents a micro-grid system based on wind and hydro power sources and addresses issues related to operation, control, and stability of the system. The micro-grid system investigated in this paper represents a case study in Newfoundland, Canada. It consists of a small hydro generation unit and a wind farm that contains nine variable- speed, double-fed induction generator based wind turbines. Using Matlab/Simulink, the system is modeled and simulated to identify the technical issues involved in the operation of a micro-grid system based on renewable power generation units. The operational modes, technical challenges and a brief outline of conceptual approaches to addressing some of the technical issues are presented for further investigation.Key words: Renewable power generation, Distributed generation, Micro-grid, Simulation Reference [1] T.

261. | Hardware Implementation of Collision Avoidance in Inter–Vehicular ADHOC Network Using Zigbee and Stellaris ARM Cortex-M4
Hardware Implementation of Collision Avoidance in Inter–Vehicular ADHOC Network Using Zigbee and Stellaris ARM Cortex-M4Abstract: To avoid accidents on highway roads, it is necessary to maintain safe distance between vehicles referred as "Inter-Vehicular Distance". A warning system should be employed inside the vehicle, so that the vehicle could sense the distance between other vehicles by using GPS co-ordinates and ADHOC wireless network and then intimate it to the driver. The main objective of this paper is to implement the Inter Vehicular Adhoc network (IVAN) using Zigbee technology and developing the control circuit using Texas Instruments Stellaris launch pad which uses LM120XL ARM Cortex M4 processor. A graphical LCD is used to display the nearby vehicles dynamic information like position, speed of the vehicle, acceleration, door lock status, break failure, etc., The Zigbee wireless technology itself provides features like data Integrity, low power consumption, low cost, wide coverage area, large network up to 65536 nodes when compared with other wireless technologies. Another objective of this paper is to secure the information passing via Inter-Vehicular ADHOC wireless Network and protect it from intruders. For this a Secure-Pre warning Collision Algorithm (S-PWCA) is implemented in firmware to make the IVAN message more secure. The implementation results show the Zigbee technology is best suit for the IVAN by taking advantage of Low power and coverage areaKey words: IVC, IVAN, IVCN, PKI, S_PWCA Reference [1] Falko Dressler_, Frank Kargly, J¨org Ottz, Ozan K.

262. | Adaptive K-Means Clustering For Improving Non- Local Means Filtering
Adaptive K-Means Clustering For Improving Non- Local Means FilteringAbstract: Recording devices whether analog or digital, have traits which make them susceptible to noise. In selecting a noise reduction algorithm, one must weigh several factors. Image denoising is defined as a method to recover a true image from an observed noisy image and is applied in display systems to improve the quality of image. One of the popular denoising methods, NLM, produces the quality of image compared than other denoising methods. We propose to improve non local means and using rotationally invariant block matching (RIBM) into the NLM framework. NLM applies moment invariants based K-means clustering on the Gaussian blurred image, which provides better classification before weighted averaging.Index Terms: Image, Denoising, NLM, RIBM, Clustering Reference [1] L.

263. | Experimental Analysis of Vibration of Ball Bearing Considering Solid Contaminants in Lubricants
Experimental Analysis of Vibration of Ball Bearing Considering Solid Contaminants in LubricantsAbstract: Rolling element bearings are common in any rotating machinery. The rolling element bearings subjected to failure under continuous running. Therefore they have received great attention in the field of condition monitoring. Different methods are detection and diagnosis of the bearing defects. Among them the commonly used technique is vibration signature analysis. The information obtained from the system vibration can be used for identifying its response subjected to various conditions. In rolling element bearing, contamination of lubricant grease by solid particles is one among the several reasons for early bearing failure. The main objective of this project is to investigate the effect of lubricant contamination by solid particles on rolling element bearing. This work is carried out to determine the vibrations on good and defective bearing in healthy grease and contaminant grease conditions. Obtained the vibration characteristics of healthy grease tested ball bearings are compared with those of contaminant grease tested ball bearings. Vibration signals are acquired from the ball bearings assembled in an experimental rig. The radial load was applied to the outer ring of the test bearing. An accelerometer placed on bearing housing measures radial vibration both in vertical and horizontal. The SKF-LGWA type of lubricants is used in this test, and also different types of solid particles are used as contaminants. The effect of contaminant concentration and particle size on vibration is to be studied. A way of monitoring machinery performance during operation is through mechanical vibration measurement. In rolling bearings, a sudden increase in vibration can be indicative of failure occurrence. In other techniques such as grease analyses and temperature monitoring can also provide warning of faults. But here, vibration monitoring is more versatile since it can reveal a wider range of faults.Key words: Condition monitoring, Contaminants, Grease, Particle size, Ball bearing Reference [1] Amarnath.M, Shrinidhi.R, Ramachandra.A, Kandagal.S.B (2004), "Prediction of defects in antifriction bearings using vibration signal analysis", IE (I) Journal-MC, Vol 85.

264. | Development of Functional Chapatti from Texturized Deoiled Cake of Sunflower, Soybean and Flaxseed
Development of Functional Chapatti from Texturized Deoiled Cake of Sunflower, Soybean and FlaxseedAbstract: Effect of texturized defatted meal of sunflower, soybean and flaxseed on quality characteristics of chapatti was investigated. Texturized defatted meal of sunflower, soybean and flaxseed was blended at 10%. 20%, 30% and 40% levels with wheat flour (atta) for making chapatti making. Chapattis were evaluated for physical, textural, sensory and functional properties. Proximate analysis of defatted sunflower meal had 2.56% moisture, 2.53% fat, 43.38% protein, 13.07% fiber and 32.54% protein digestibility. The defatted soybean meal had 2.70% moisture, 2.26% fat, 52.86% protein, 3.29% fiber and 56.33% protein digestibility. The defatted flaxseed meal had 2.61% moisture, 2.71% fat, 38.24% protein, 12.24% fiber and 43.77% protein digestibility. The cutting force for chapattis increased with increased level of texturized defatted meal of sunflower, soybean and flaxseed. Sensory, color and overall acceptability of chapattis were negatively affected when level of texturized flour increased as compared with the control. Overall acceptability scores were maximum for control and chapattis with 10% texturized defatted meal of sunflower, soybean and flaxseed. Functional properties such as water absorption index, foaming capacity and protein digestibility were increased while water solubility index and fat absorption capacity decreased with increased levels texturized defatted meal. The result showed that texturized defatted meal serve as good substitute to wheat flour with increased protein content in chapatti production and utilization.Key words: Chapatti, Deoiled cake, Flaxseed, Sunflower, Soybean Reference [1] E Derbyshire, D.

Performance Comparison on Face Recognition System Using Different Variants of Back-Propagation Algorithm with Radial Basis Function Neural NetworksAbstract: This paper presents the performance comparison of two architectures of neural networks: multi-layer perceptron (MLP) neural networks and radial basis function (RBF) neural networks on face recognition system (FRS). We are training MLP using different variants of back-propagation (BP) algorithm. AT&T database has been used for performance comparison. The BP is gradient descent based iterative algorithm which takes larger training time for high dimensional pattern recognition problem. Local minimum, improper learning rate and over-fitting are some of the other issues. To overcome these issues, we used RBF based FRS that is robust than other conventional methods like BP algorithm and has better performance of recognition rate. The training results show that in all the situations, RBF provides better generalization performance in compared of BPKey words: Face recognition, Performance Comparison Reference [1] Yanping Bai, Haixia Zhang and Yilong Hao," The performance of the BP algorithm with varying slope of the activation function", Chaos, Solitons and Fractals 40 (2009) 69–77.

Implementation of Scaled Down Model of Heterogeneous Spectrometers for Radio Astronomy Applications Using Xilinx FpgasAbstract: we have developed a software package to automatically generate spectrometers with minimal user input.Spectrometer design is often done by building the instrument from scratch. We have automated this design, creating a parameterized spectrometer that only requires a recompile to implement a change in specification. This spectrometer combines FPGAs and GPUs, doing coarse channelization on the FPGA and sending each subband to the GPUs for further processing. The server software is designed for flexibility, allowing astronomers to easily modify the processing algorithm run on the GPU and customize the instrument to their science goals. This project is about a heterogeneous design, allowing us to benefit from the strengths of FPGAs. A design called the Packetized Astronomy Signal Processor, or PASP. In this project a scaled down version of spectrometers are implemented for radio astronomy applications using VHDL for Xilinx FPGA platform. Modelsim Xilinx edition (MXE) will be used for simulation and functional verification. Xilinx ISE will be used for synthesis, P&R and bit file generation.

267. | Loss Reduction in Radial Distribution Network by Optimal Placement of Type – I DG Using Modified Direct Search Algorithm
Loss Reduction in Radial Distribution Network by Optimal Placement of Type – I DG Using Modified Direct Search AlgorithmAbstract: In this paper, Direct Search Algorithm is implemented to determine the optimal sizes of Type – I Distributed Generators (DGs) and optimal locations such that maximum possible reduction in real power loss is obtained. Type – I DG injects both active and reactive powers. The algorithm searches for all possible locations in the system for a particular size of DG and places it at the bus which gives maximum reduction in active power loss. The optimal sizes of DGs are chosen to be standard sizes i.e., discrete sizes of DGs are considered. The algorithm is tested on 33 bus and 69 bus Radial Distribution Systems. The loss reduction obtained in this paper for the 33 bus and 69 bus test systems are highest compared to other techniques in the literature. Power factor of the DG is considered in this study is 0.85. On 33 bus system, without placement of DGs the loss is 211 kW whereas after placement it is 15.50 kW. There is a reduction of 92.65% in the losses. Before placement of DGs, the power loss is 5.37% of the total power supplied by the slack bus. After optimal placement by the MODIFIED DSA algorithm, the active power loss is 0.415% of the total power supplied by the system. On 69 bus system, without placement of DGs the loss is 225 kW whereas after placement is 5.75 kW. There is a reduction of 97.44% in the losses. Before placement of DGs, the power loss is 5.58% of the total power supplied by the slack bus. After optimal placement by the MODIFIED DSA algorithm, the active power loss is 0.15% of the total power supplied by the system. As the loss is less than 2%, the system is considered as Loss Less Distribution System. It is implemented using MATLAB/Simulink.Key words: Loss Less Distribution, Optimal DG Placement, Distribution Systems, Modified Direct Search Algorithm (MODIFIED DSA). Reference [1] M.

268. | Design and Implementation of Digital CMOS VLSI Circuits Using Dual Sub-Threshold Supply Voltages
Design and Implementation of Digital CMOS VLSI Circuits Using Dual Sub-Threshold Supply VoltagesAbstract: Power dissipation in high performance systems requires more expensive packaging. In this situation, low power VLSI design has assumed great importance as an active and rapidly developing field. As the density and operating speed of CMOS VLSI chip increases, power dissipation becomes more significant due to the leakage current when transistor is OFF. This can be observed in both combinational and sequential circuits. Static power reduction techniques are achieved by means of operating the transistor either in Cut-off or in Saturation region completely and by avoiding the clock in unnecessary circuits. In this work, "Dual sub-threshold voltage supply" technique is used to operate the transistor under either OFF or ON state by applying some voltage at the gate of the MOS transistor. The designed circuits are simulated by using Mentor Graphics Backend Tool. With this technique, nearly 10-75% of the power dissipation is reduced for designed circuits. Thereby, the performance of circuit can be increased.Key words: Digital circuits, Dual sub-threshold leakage current, Power dissipation, Performance. Reference [1] Kaushik Roy, Amit Agarwal, Chris H.

A Comparative Study B/W Black Cotton Soil and Alluvial Soil for Economical Pavement Design by Lime & Fly-Ash StabilizationAbstract: As we know the road development is one of the major parts of growing infrastructure & Pune, which is expanding at a very fast rate, the construction of roads is of major concern. Fly Ash is one of the abundant forms of Solid Waste produced at thermal power plants. Its disposal is a big problem keeping both these concerns in mind it was tried to come out with a project which will integrate Road development and Fly ash disposal. Thus, in this project we intend to use Fly ash & Lime in roads which will help us in following manner: High volumes of Fly ash will be used which will save the dumping sites to be used for better purposes. The use of fly ash will reduce the consumption of high volumes of fertile soil that can be used for cultivation purposes. Due to binding properties of lime & Fly ash, the pavement designed will be of higher strength. Overall thickness of the pavement can be reduced. Two types of soils were used in this project, namely Alluvial Soil and Black Soil taken from nearby Pune.

270. | Increasing The Strength Of Audio Watermarking Against Desynchronization Attacks
Increasing The Strength Of Audio Watermarking Against Desynchronization AttacksAbstract: Rapid evolution of digital technology has improved the ease of access to digital information enabling reliable, faster and efficient storage, transfer and processing of digital data. It also leads to the consequences of making the illegal production and redistribution of digital media easy and undetectable. Hence, the risk of copyright violation of multimedia data has increased due to the enormous growth of computer networks that provides fast and error free transmission of any unauthorized duplicate and possibly manipulated copy of multimedia information. In audio watermarking area, the robustness against desynchronization attacks, such as TSM (Time-Scale Modification) and random cropping operations is still one of the most challenging issues. To enable the embedding of multiple watermarks a multi-bit robust audio watermarking algorithm based on the two statistical features is proposed by modifying the histogram. The audio histogram with equal-sized bins is extracted from a selected amplitude range referred to the audio mean, and then the relative relations in the number of samples among groups of three neighboring bins are designed to carry the watermark by reassigning the number of samples in the bins. The watermarked audio signal is perceptibly similar to the original one. Simulation results demonstrated that the hidden message is very robust to the TSM, cropping, and a variety of other distortions for Audio.Key words: Audio watermarking, cropping, histogram, jittering, synchronization, TSM.

271. | A Closer Look at SMS-Based E-Banking Services Using Elliptic Curves
A Closer Look at SMS-Based E-Banking Services Using Elliptic CurvesAbstract: With the ushering in of cellphone technology in the country, many financial institutions have launched SMS-based E-banking Services. However, the transmission of SMS in cellphone networks is not secure as the message is sent in plaintext form. So, the content of the message may be exposed to anybody. As SMS-based E-banking Services have become so popular in our daily life, there is a great demand from the users to implement them in a secure environment. Therefore it is desirable to make SMS-based e-banking Services secure by additional encryption. In this paper, we study SMS-based E-Banking Services using Elliptic Curves. We also give the benefits of using Elliptic Curves over RSA in SMS-based E-Banking Services.Key words: Elliptic Curve, SMS, Encryption, Decryption, E- Banking Reference [1] Ranbir Soram, Mobile SMS Banking Security Using Elliptic Curve Cryptosystem, International Journal of Computer Science and Network Security, Vol 9, No. 6, 2009.

272. | Impact of Variable Transmission Range and Scalability With Respect To Mobility and Zone Size On Zone Routing Protocol Over Manets
Impact of Variable Transmission Range and Scalability With Respect To Mobility and Zone Size On Zone Routing Protocol Over ManetsAbstract: A variety of protocols are used in ad hoc network but the most popular protocol one is Zone Routing Protocol (ZRP). ZRP is a hybrid routing protocol. Transmission power affects the design and performance of all the protocols in Mobile Ad hoc Networks (MANETs). Mobility of nodes and selection of Zone Size in ZRP are also the major issues. In this paper, the impact of Transmission Ranges and Scalability by varying Mobility rate along with Zone Radius on QoS based performance metrics has been analyzed. The environment has been simulated using NS2.33 Simulator. The objective of our work is to analyze that at what speed and by taking how much zone radius ZRP will be able to perform efficiently and effectively for Mobile Ad hoc Networks.Key words: MANETs, ZRP, QoS, Transmission Range.

273. | Removal of Chlorine Residual in Tap Water by Boiling or Adding Ascorbic Acid
Removal of Chlorine Residual in Tap Water by Boiling or Adding Ascorbic AcidAbstract: Society's preference for bottled water mainly comes from a dislike of the mildly pungent taste and odor of tap water. Such odor and taste may be caused by chlorine residual (in the form of free chlorine or chloramines), which is maintained in a water distribution system to prevent regrowth of microorganisms and is thus present in tap water. To encourage individuals who drink bottled water to shift to tap water, which affords numerous financial and environmental advantages, a simple, effective and low-cost method of reducing chlorine residual in tap water is essential. Two methods of reducing chlorine residual, boiling tap water and adding ascorbic acid to tap water, were tested. The results showed that, for free chlorine, a quick and cheap way to reduce chlorine residual is to add ascorbic acid, which if added in an equal molar amount to free chlorine would completely eliminate chlorine residual within 1 min. For monochloramine, a quick and cheap way to reduce chlorine residual is also to add ascorbic acid, but in greater quantity due to some ascorbic acid being oxidized by oxygen in the air. Although boiling is slower, it is effective in removing low concentrations of chlorine residual.Key words: Drinking Water, Tap Water, Chlorine Residual, Boiling, Ascorbic Acid. Reference [1] L.

Designing Of Hydraulic Bollard System Using Accumulator Bladder for Better Security SolutionsAbstract: Bollards are largely used for stopping/control of vehicular traffic and allow the pedestrians passage at entry and exit points for better safety and movement control indifferent places like Shopping malls, Govt. Building, DRDO's, Military Installation , Airport, Oil Refineries and Depots, Gas Plants, Educational Institutions etc. Bollards can be operated manually, electrically, or hydraulically and respond to a wide range of security specifications and design requirements. A bollard designed with hydraulic accumulators system proves to be more successful in providing protection to pedestrians and infrastructure. A hydraulic accumulator stores fluid under pressure and can serve a number of functions within a hydraulic system. It's an item that can provide year of trouble-free service. Thus in country like India, where population rises with very high rate and no control on traffic Bollards are one of the only choices for pedestrian friendly protection from vehicle attack.Reference [1] Bangalore Krishna-Prasad Protective Bollard Design for High Speed Impact Energy Absorption, Wichita State University, 2006.

Multi Resolution Analysis of ECG for Arrhythmia Using Soft-Computing TechniquesAbstract: in this paper, ECG signal analysis for arrhythmia detection using discrete wavelet transform and Back Propagation Neural Network is addressed . Several algorithms have been proposed to classify ECG arrhythmias; however, they cannot perform very well. Therefore, in this paper, an expert system for Electro Cardio Gram (ECG) arrhythmia classification is proposed. Proposed technique used to detect the abnormal ECG Sample and classify it into two different classes (normal and Arrhythmia). We have employed MIT-BIH arrhythmia & Normal Sinus Rhythm (NSR) database and chosen 62 files of ten second recording where 14 files are considered as normal class and 48 files of Arrhythmia class out of total 62 files. The features are break up in to two classes that are DWT based features and morphological feature of ECG signal which is an input to the classifier. Back Propagation Neural Network (BPNN) are employed to classify the ECG signal and the stem performance is measured on the basis of percentage accuracy. For the normal class sample 100% of accuracy is reached whereas 97.9% accuracy is achieved for Arrhythmia class sample. The overall system accuracy obtained is 98.4 % using (BPNN) classifier.Key words: ECG, Arrhythmia, , Discrete Wavelet Transform (DWT), BPNN, Accuracy Reference [1] Hari Mohan Rai, Anurag Trivedi "Classification of ECG Waveforms for Abnormalities Detection using DWT and Back Propagation Algorithm" International Journal of Advanced Research in Computer Engineering & Technology Volume 1, Issue 4, June 2012 [2] S.

An Overview Study of Game EnginesAbstract: We live in a world where people always try to find a way to escape the bitter realities of hubbub life. This escapism gives rise to indulgences. Products of such indulgence are the video games people play. Back in the past the term "game engine" did not exist. Back then, video games were considered by most adults to be nothing more than toys, and the software that made them tick was highly specialized to both the game and the hardware on which it ran. Today, video game industry is a multi-billion-dollar industry rivaling even the Hollywood. The software that drives these three dimensional worlds- the game engines-have become fully reusable software development kits. In this paper, I discuss the specifications of some of the top contenders in video game engines employed in the market today. I also try to compare up to some extent these engines and take a look at the games in which they are used.Key words: engines comparison, engines overview, engines specification, video games, video game engines Reference [1] Jason Gregory, Game Engine Architecture (A K Peters/CRC Press, Taylor & Francis Group, 6000 Broken Sound Parkway NW, Suite 300, Boca Raton, FL 33487-2742) [2] Tomas Akenine-Moller, Eric Haines, and Naty Hoff man Real-Time Rendering (3rd Edition).

283. | Application of Mechanical Energy to Activate Pozzolanas
Application of Mechanical Energy to Activate PozzolanasAbstract: Mechanical energy has been used to improve the reactivity of burnt clay pozzolana from two clay deposits in Ghana, Mankranso and Mankessim, by subjecting the pozzolanas to various types and degrees of milling – hammer milling, ball milling and roll milling. The particle sizes and specific surface areas obtained by these types/degrees of milling were analyzed and their effect on the strength development of Portland pozzolana cement mortar cubes prepared from the pozzolana samples evaluated. Both pozzolana samples were chemically suitable with total SiO2+Al2O3+Fe2O3 content ≥ 70% as stipulated by the ASTM C 618 standard. Roll milling gave the finest pozzolana powders with characteristic particle sizes, x of 6 μm and 10 μm respectively for Mankessim and Mankranso pozzolanas. The respective Blaine indices obtained by roll milling were 1311 m2/kg and 1395 m2/kg. Both pozzolana samples showed increase in fineness with increasing duration of continuous ball milling without classification until agglomeration, evidenced by a significant increase in the characteristic particle size, started after 42 h. Compressive strengths for the Portland pozzolana cement mortar cubes prepared from the two pozzolana samples showed that both pozzolanas could be used to replace up to 40% ordinary Portland cement whilst satisfying the ASTM C 595 minimum requirement of 24.1 MPa. Mankessim pozzolana cement mortar cubes gained a 28-day compressive strength of 30.3 MPa after roll milling and 25.6 MPa after 36 h of ball milling whereas Mankranso pozzolana cement mortar gained a 28-day compressive strength of 29.6 MPa after roll milling and 27.7 MPa after 36 h of ball milling—both at 40% ordinary Portland cement replacement.. The 90-day compressive strengths showed that at 50% cement replacement, mortar cubes prepared from Mankranso and Mankessim pozzolanas gained enough strength to satisfy the ASTM C 595 and the EN 197-1 standard requirement. Hammer milling proved to be the least efficient means of activation as compressive strength values obtained at 28 days were below the ASTM C 595 minimum of 24.1 MPa at cement replacement levels above 30%.The activated pozzolanas were found suitable to replace up to 40% of OPC for most ordinary housing construction purposes not requiring high early strength class of cements.Key words: Activated pozzolana, ball milling, roll milling, hammer milling, compressive strength and setting time.

An Analytical Delay Expression For Deep Sub-Micron RLC InterconnectAbstract: Continuously scaling down devices is the main goal in very deep sub-micron (VDSM) technology. Though using VDSM technology we are achieving many advantages. But circuit performances are badly affected because of secondary effects like crosstalk noise. According to International Technical Roadmap for Semiconductors(ITRS) 2011 report today's DSM technology outsmarted Moore's law to work in a new industrial trend called "More than Moore" (MtM). To accomplish this, it is necessary to analyze the timing behavior of the interconnect. Various techniques have been proposed for the delay analysis of global interconnects. Those techniques are based on either simulation techniques or analytical formulae. Simulation tools such as SPICE give the most accurate result for verifying timing issues. In our model aggressor and victim lines are represented using a distributed network which is used to derive a closed form on chip analytical model for RLC global interconnects. Then the model is used to get a simplified expression for delay. Results of proposed model are then compared with the results of BSim4 120nm technology which shows very marginal error with faster simulation time.Key words: Crosstalk, Coupling, Delay, Interconnect, VLSI Reference [1] Mingcui Zhou, Wentai Liu, Mohanasankar Sivaprakasam "A Closed-form Delay Formula for On-Chip RLC Interconnects in Current-Mode Signaling" Department of Electrical Engineering, University of California at Santa Cruz, CA 95064, USA ©2005 IEEE.

285. | A Design of H-Bridge Converter for Power Conversion System
A Design of H-Bridge Converter for Power Conversion SystemAbstract: Now a day's wind turbine power outputs are 2MW and above. If transmission of high power with low voltage conversion system will suffer from a high transmission current. The transmission of high current from wind generator to grid we require larger cable size which is increases losses and cost of the cables as well as voltage drop. This paper proposes a modular, medium voltage and high- power converter topology for the large permanent magnet wind generator system, eliminating the grid-side step-up transformer. The converter modules are cascaded to achieve medium voltage output. Each converter module is fed by a pair of generator coils with 90⁰ phase shift to get the stable dc-link power. The power factor correction (PFC) circuit enables the generator to achieve unity power factor operation and the generator armature inductance is used as ac -side PFC boost inductance. At the grid-side, H-bridge inverters are connected in series to generate multilevel medium voltage output and the voltage-oriented vector control scheme is adopted to regulate the converter active and reactive power transferred to the grid. The Simulation results with a 2MW wind turbine system.

Biometric Cc Cam for Identifying a Particular Object or Person InitiallyAbstract: Biometrics is not novel to everyone. But we are eager to follow the features provided by biometrics for our security in offices and in any other security required areas. But we are not bothering about the nation security. Today the biometric cc cam is not completely available for our nation security. So we tried to propose a new concept in biometric cc cams to protect our nation. Biometric cc cam is used to trace capture all the pottages and they are stored in the database of control room. If any attacks occurred they will search for proofs at that stage. But we are proposing cc cam with an inbuilt chip which consists of the pottages of most wanted persons and it have the capability of ringing an alarm when any one of those persons whose information is pre stored with a chip. This alarm alerts whole area and also the control room. With this camera we can easily trace the terrorists and any wanted persons.

Mechanistic-Empirical Study of Sensitivity of Truck Tire Pressure to Asphalt Pavement Thickness in EgyptAbstract: Designing, improving and reducing distresses of highway network is an essential responsibility of the roads researchers. Truck tire inflation pressures have steadily increased in the recent decades. In the past, damage resulted from load application to highway pavements focused primarily on the magnitude and frequency of axle loads. In recent years, the effect of increased truck tire pressure on flexible pavements responses has become a subject of great concern. The main objective of this study is to determine which layer thickness is more sensitive to improve the performance of the flexible pavement with respect to the variation of traffic tire pressure. The performance of pavement will be mentioned by optimum tire pressure measure where fatigue and rutting lives are equal. Moreover, the pavement life will be determined as a function of the tire pressure and the most effective thickness on the performance of the pavement due to the variation of traffic tire pressure. Results demonstrate that, the base course thickness is the key element which can cause a marked decrease in the optimum tire pressure. Moreover, the optimum tire pressure should not exceed 0.80 N/mm2 with 375.0 mm optimum base thicknesses.Key words: Flexible Pavement, KENLAYER , Pavement Life, Pavement Strains, Tire Pressure Reference [1] El-Hamrawy, S.

A Simple Predictive Pwm Voltage Controlled Technique for Implementation of Single Phase Inverter with Precesion RectifierAbstract: A single-phase PWM inverter is presented to alleviate harmonic components of the output voltage and the load current. To keep the output voltage being sinusoidal and to have the high dynamic performances even in the cases of load variations and the partial magnetization in filter inductor, the modified digital predictive controller is designed and implemented on a prototype. The validity of the proposed inverter is verified through experiment. Additionally, low-ripple sinusoidal-current waveforms are generated with almost unity power factor.

These are related to the environmental conditions, length of the line and various stability related issues. The VAR plays important role in maximising the power transfer through a transmission line. The FACTS Controllers have a major part to play in the VAR Management, in order to increase the maximum loading capability. This gives an additional benefit of enhancing the voltage stability margin of the entire system as well.

Vortex Tube
Effect of Hot End Obstruction and Nozzle on the Performance of Vortex TubeAbstract: The vortex tube is a very simple device injected with pressurized air through tangential nozzle which splits in to two streams of low pressure air, one warmer leaves near the periphery at plug end known as free vortex and one colder leaves via an orifice at the opposite end known as forced vortex. The entry and exit of tube are key parameters affecting the performance of vortex tube. The nozzle at entry effects the formation of free vortex flow inside the tube and end region of hot pipe effects the converging of air and controls the forced vortex flow pattern. Providing an obstruction at the end of hot pipe boosts up the desired flow and enhances the energy separation. In the present work an attempt is made to revise the effect of inlet pressure, cold fraction, end obstruction of hot pipe end and also the nozzle on the performance of vortex tube. A series of tubes with different level of obstruction and different nozzle inlet diameters were tested. The results indicate that temperature drop increases with increase of nozzle diameter up to 5mm and no significant improvement is observed beyond it and temperature drop is effective at moderate end obstruction area.Key words: Vortex flow, End obstruction, cold fraction, Temperature separation.

Embedded Smart Video Surveillance Using HistogramAbstract: Video surveillance has long been in use to either monitor security sensitive areas or to know the statistic details for business purposes. Typical application includes banks, shopping complexes, Railway stations, crowded public places and borders. The advancement in computing power, availability of large-capacity storage devices and high speed network infrastructure paved the way for cheaper, multi sensor video surveillance systems. Traditionally, the video outputs are processed online by security officials and usually saved to tapes for later use only after a forensic event. However, assisting the human operators with identification of important events in video by the use of "smart" video surveillance systems has become a critical requirement. The making of video surveillance systems "smart" requires fast, reliable and robust algorithms. This mandates for this smart feature to run on camera itself; embedded software using spare processing capacity in Camera's Digital signal processor (DSP). In this article we propose a novel algorithm which is small in footprint and quick in identifying the activity using Event Trigger and process the image using histogram which can be embedded in DSP system.Key words: Digital Signal Processor, Event Trigger, Histogram, Smart Surveillance, Video Surveillance Reference [1] Chipwrights, "Programmable Visual Signal Processors", www.chipwrights.com [2] W.E.L.

297. | A Comparison of Symmetrical and Asymmetrical Three-Phase Cascaded Multilevel Inverter Using Flexible Control Technique for DTC Induction Motor Drives
A Comparison of Symmetrical and Asymmetrical Three-Phase Cascaded Multilevel Inverter Using Flexible Control Technique for DTC Induction Motor Drives<Abstract: There are problems in the limitations of conventional inverters, especially in high-voltage and high-power applications. Recently multilevel inverters are becoming increasingly popular for high-power applications due to their improved harmonic profile and increased power ratings. Several studies have been reported on multilevel inverters topologies, control techniques, and applications. However, there are few studies that actually discuss or evaluate the performance of induction motor drives associated with three-phase multilevel inverter. This paper presents a comparison study of symmetrical and asymmetrical for a cascaded H-bridge multilevel using flexible control technique and also direct torque control (DTC) for induction motor drive. In this case, symmetrical and asymmetrical arrangements of five-level, seven-level, nine-level and eleven H-bridge inverters are compared using flexible control technique vector space in order to find an optimum arrangement with lower switching losses and optimized output voltage quality. So, as to decrease the THD value (total harmonic distortion) the number of levels is increased. The experiments show that an asymmetrical configuration provides nearly sinusoidal voltages with very low distortion, using less switching devices. Moreover, torque ripples are greatly reduced by increasing number of levels we can bring step waveform to nearly sinusoidal waveform by decreasing the THD value. Thus ripples are reduced and efficiency is increased.Index Terms: THD (Total harmonic distortion), Direct torque control (DTC), multilevel inverters, induction motor. Reference [1] M. F.

298. | Improvement of DVR Performance Using Fast and Effective Control Scheme under Various Loads
Improvement of DVR Performance Using Fast and Effective Control Scheme under Various LoadsAbstract: The dynamic voltage restorer (DVR) has become popular as a cost effective and efficient solution for the protection of sensitive loads from voltage sags. This paper reports a novel control scheme for DVR to achieve fast response and effective sag compensation capabilities. The DVR, which is placed in series with sensitive load, must be able to respond quickly to voltage sag if end user's of sensitive equipment are to experience no voltage fluctuations. But the proposed control scheme is controls the magnitude and phase angle of the injected voltage for each phase separately. Fast least error squares digital filters are used to estimate the magnitude and phase of the measured voltages. The utilized least error squares estimated filters considerably reduce the effects of noise, harmonics and disturbances on the estimated phasor parameters. This enables the DVR to detect and compensate voltage sags accurately, under linear and non linear load conditions. The proposed control system does not need any phase locked loops. It also effectively limits the magnitude of the modulating signals to prevent over-modulation. Both sides, separately controlling the injected voltage in phase enable the DVR to restore load voltage in short time interval (5ms) with zero steady state. Results of the simulation studies in the MATLAB/SIMULINK software environment indicate that the proposed control scheme performs satisfactorily under linear, non linear loads and BLDC motor drive.Key words: BLDC motor, DVR, Least error square digital filters, voltage sag.

299. | Chromatic Dispersion Mitigation in Single Carrier High Speed Coherent Optical Communication Using Digital Signal Processing Techniques
Chromatic Dispersion Mitigation in Single Carrier High Speed Coherent Optical Communication Using Digital Signal Processing TechniquesAbstract: Optical fiber networks have been emerged to be the backbone of global communication infrastructure in present world. But, they are currently experiencing an unprecedented level of stress in order to meet the demand of increasing bandwidth-hungry applications. Moreover signals are frequently subjected to distortion due to optical fiber impairments while being propagating through a fiber optic cable. This paper demonstrates digital signal processing (DSP) based chromatic dispersion (CD) estimation and mitigation technique for single carrier high speed coherent optical communications. Coherent detection permits the optical field parameters (amplitude, phase and polarization) to be available in the electrical domain enabling new opportunity for multi-level signaling (M-ary PSK and M-ary QAM modulation). That is why Coherent detection employing QAM modulation formats have become one of the most promising technologies for next generation high speed transmission systems due to the high power and spectral efficiencies. In recent days, the realizations of DSP algorithms for estimating and mitigating the chromatic dispersion in the coherent transmission systems are the most attractive investigations.

A Personalized User Concept Model For Web Information GatheringAbstract: Nowadays It has become very easy to access information from internet via World Wide Web. If we want any information through search engine they do not deliver the relevant information because they are programmed as one size fits all. Ironically the very vast size of this collection has become an obstacle for information retrieval. It is very logical and reasoning to personalize the retrieval system specific to the preference of a user. However,when representing user profiles,many models have utilized only knowledge from either global knowledge base or a user local information This paper work contribute in improving the accuracy of information gather to personalize the user profile by combining the knowledge base and user local instance repository with 2D ontology mining method is introduced: Specificity and Exhaustivity. This concept model cannot be proven in laboratories; many web ontologists have observed it in a user behavior the results show that this ontology model is successful.Key words: Local instance repository, Ontological user profiles, Personalization, Semantic relations, User context Reference [1] Xiaohui Tao, Yuefeng Li, and N.

302. | Fpga Based Moving Object Detection Algorithm Implementation for Traffic Surveillance
Fpga Based Moving Object Detection Algorithm Implementation for Traffic SurveillanceAbstract: The main objective of this paper is detection of vehicles by background subtraction technique and the automatic surveillance of traffic based on the number of vehicles. The algorithm takes into consideration three main techniques namely Background Subtraction, Edge Detection and Shadow Detection. Background Subtraction block is sub-divided into Selective and Non-selective parts to improve the sensitivity and give accurate background. Edge detection helps to detect the exact boundaries of moving vehicles. This is followed by the shadow detection block that removes the falsely detected pixels that are generated due to shadow of the vehicle. By analyzing the output of the blocks discussed above, the final mask is generated. The mask along with the input frame is processed to give the final output frame where the detected object is highlighted. Furthermore, parameters such as number of blobs per frame (vehicles) and the area of blobs can be used for traffic surveillance. The algorithm of object detection is implemented on FPGA using VHDL. Spartan-6 Development Board is used for implementation of the same.Key words: FPGA, Image Processing, SPARTAN6, Traffic surveillance, VHDL. Reference [1]. Sen-Ching S.

CFPRS: Collaborative Filtering Privacy Recommender System for Online Social NetworksAbstract: Social-networking sites (SNSs) are known to be among the most prevalent methods of online communication. Owing to their increasing popularity, online privacy has become a critical issue for these sites. The tools presently being utilized for privacy settings are too ambiguous for ordinary users to understand and the specified policies are too complicated. In this paper, a collaborative filtering privacy recommender system is proposed. The implementation of the system was initiated by examining the users' attitudes toward privacy; whereby the most significant factors impacting users' attitudes towards privacy were determined to be location, religion and gender. The next step involved the classification of the users into various groups on the basis of the above factors. The paper presents a method of integrating the identified factors into the collaborative filtering algorithm to improve the filtering process. The evaluation of results reflects the accuracy of recommendations and proves that the use of the clustering model assisted the CF recommender in its creation of appropriate recommendations for each user.Key words: Social Networks, Privacy, Collaborative Filtering, Recommender Systems, Privacy Factors.

307. | A Novel Algorithm To Detect Changes In Surveillance Video
A Novel Algorithm To Detect Changes In Surveillance VideoAbstract: Tracking changes in an acquired surveillance video is essentially impractical task for the human due to the complexity of the monitoring process, specifically for a long-time period. Finding changes in a sequence of images captured by surveillance video system is a complicated task for the human and it is complicated by fitting it to a classification model. Given a sequence of images, we are concerned with automatically detecting the occurrence of changes in the given sequence of images. In this paper, the problem of detecting changes in digital images captured by surveillance video system is explored. A novel algorithm, involving correlation coefficients and eigenstructure-based Mosaab distance measure, is suggested. The proposed algorithm is a mobile-based application, that can be used to process pixel-based data (i.e., sequence of images) at camera locations and send only real-time numeric results to client's mobile device(s) . Therefore, the aim of proposed algorithm is to analyize and eliminate the amount of pixel-based data to be sent via the network. Consequently, the received real time numeric results can be visualized using an application software installed in client's mobile device. The main function of the mobile-based application software is to illustrate the received results as a real-time graph. The proposed algorithm shows effectiveness in eliminating the flow of raw pixel-based data in the network.Key words: Mosaab-distance measure, correlation coefficient, surveillance video system.

Designing and Analysis of Roll Cage of an ATVAbstract: Automotive chassis is an important part of an automobile. The chassis serves as a frame work for supporting the body and different parts of the automobile. Also, it should be rigid enough to withstand the shock, twist, vibration and other stresses. Along with strength, an important consideration in chassis design is to have adequate bending stiffness for better handling characteristics. So, strength and stiffness are two important criteria for the design of the chassis. This report is the work performed towards the static structural analysis of the All-Terrain Vehicle chassis. Structural systems like the chassis can be easily analyzed using the finite element techniques. So a proper finite element model of the chassis is to be developed. The chassis is modeled in Solid Works.

Secure Scheme For User Authentication And Authorization In Android EnvironmentAbstract: Providing ultimate security in sensitive transaction and communication of online premium application is still a question mark of standardization in the area of networking and security. It has been seen that currently majority of the authentication and authorization techniques are usually designed on the top of One Time Password on user trusted hand held device. However, due to various lethal threats on mobile security systems, it can be said that existing security is not sufficient. Keeping in viewpoint of security on effective authentication and authorization, this paper proposes a technique that exponentially minimizes the operational cost by using secure hash algorithms that has the potential to generate mobile-based One Time Passwords (OTPs) scheme on Android environment ensuring enhanced protection with respect to password security.

Performance of Responsibility Discovery in VLSI Circuit Using AccumulatorAbstract: Built-In Self Test (BIST) schemes have been utilized in order to drive down the number of vectors to achieve complete fault coverage in BIST applications. Weighted sets comprising three weights, namely 0, 1, and 0.5 have been successfully utilized so far for Test Pattern Generation, since they result in both low testing time and low consumed power. In this paper an Accumulator-based 3-Weight Test Pattern Generation scheme is presented; the proposed scheme generates set of patterns with weights 0, 0.5, and 1. Since accumulators are commonly found in current VLSI chips, this scheme can be efficiently utilized to drive down the hardware of BIST pattern generation, as well. The output of this pattern generator is applied to a circuit under test where the errors are detected by using MISR circuit.Index Terms: VLSI Testing, Weighted Test Pattern Generation, Built-In Self-Test (BIST), Test Per Clock, Reference [1] P.

FPGA Based Area Efficient Turbo Decoder For Wireless CommunicationAbstract: To fulfil the extensive need of high data rate transfer in today's wireless communication systems such as WiMAX and 4G LTE (Long Term Evolution), the turbo codes gives an exceptional performance. They have allowed for near Shannon limit information transfer in modern communication systems. As the performance of these codes increases, their decoding complexity is also increases and so the power consumption. To reduce this complexity without decreasing its BER (Bit Error Rate) performance a novel modification over SOVA (Soft output Viterbi Algorithm) is proposed in this paper. The proposed model is also implemented on FPGA Xilinx Virtex 5 XC5VLX85ff676-2. The simulation results over MATLAB has been shown, indicates a comparable BER as compared to LOG-MAP with reduced complexity. The synthesis results over Xilinx FPGA shows an improvement of 12% over area utilization as compared to MAX-LOG-MAP implementation. So with reduced area and low BER, a cost effective solution proposed in this paper.Key words: Turbo code, FPGA, SOVA algorithm, Log MAP algorithm, FEC (Forward Error Correction), Convolutional code (CC), BER etc. Reference [1] Qu Wei, Information theory and coding theory, Sciences Publishing House, 2005.

Lifting Based-Dwt Compression Technique Using FpgaAbstract: Image compression is one of the major image processing techniques that is widely used in medical, automotive, consumer and military applications. Discrete wavelet transforms is the most popular transformation technique adopted for image compression. Complexity of DWT is always high due to large number of arithmetic operations. A modified Distributive Arithmetic based DWT architecture is proposed and is implemented on FPGA.In this paper" LIFTING BASED-DWT" technique is proposed and is implemented on FPGA. Lifting Scheme entirely relies on spatial domain in this proposed method using LB-DWT area utilization is increased on the Vertex-5 FPGA kit. Instead of using ROM as a cache memory we are using FIFO as a storage device by which latency can be reduced and throughput can be increased.Key words: Image Compression, Discrete Wavelet Transform, Spatial Domain, Lifting Based-DWT.

319. | Growth And Characterization Of Pure And Glycine Added Morenosite Single Crystals
Growth And Characterization Of Pure And Glycine Added Morenosite Single CrystalsAbstract: Morenosite (NiSO4.7H2O) is a hydrogen bonded crystal having a wide range of applications in various fields. In an attempt to understand the effect of glycine as an impurity on the properties of morenosite crystals, we have grown by the free evaporation method at room temperature and characterized pure and glycine added morenosite single crystals. The grown crystals were characterized structurally, mechanically, optically and electrically. The densities observed indicate that the impurity molecules have entered into the crystal matrix. The grown crystals exhibit good optical transparency in the wavelength range 210-1100 nm. The second harmonic generation measurements indicate that they are nonlinear optically active. Results of microhardness measurements follow the normal indentation size effect. Electrical (AC and DC) measurements indicate that the grown crystals exhibit a normal dielectric behaviour and the electrical conduction is understood to be due to the protonic movement. The present study indicates that glycine addition plays an important role in reducing the dielectric constant εr value significantly to make morenosite crystals low-εr value dielectric materials, expected to be useful in the microelectronics industry.Key words: Crystal growth, Electrical properties, Mechanical properties, Morenosite crystals, Optical properties, Single crystals, X-ray diffraction Reference [1] R.W.G.Wyckoff, Crystal Structures (2nd edn), Vol.3, (Interscience, New York, 1960), p.839 [2] John A.

320. | Design and Implementation of CMOS VLSI Digital Circuits Using Self-Adjustable Voltage Level Technique
Design and Implementation of CMOS VLSI Digital Circuits Using Self-Adjustable Voltage Level TechniqueAbstract: In present scenario, an increasing demand for mobile electronic devices such as cellular phones, laptop computers and personal digital assistants requires the use of power efficient circuits. To minimize the power dissipation and to increase the battery lifetime, the supply voltage, VDD has been scaled down continuously. So, scaling down the supply voltage, without scaling down the threshold voltage increases the propagation delay. However the threshold voltage scaling results in substantial increases of sub-threshold leakage current, which increases the leakage or static power dissipation of the circuits. Therefore, the main aim of this work is to minimize the power dissipation by reducing leakage power. In this work, some of the combinational and sequential circuits are designed with CMOS transistors using self-Adjustable Voltage Level (SAL) technique to optimize the power dissipation. The circuits are implemented using the Mentor Graphics Backend Tool to analyze the power dissipation. With this SAL technique less than 50% of the power dissipation can be reduced for designed circuits which lead to improve performance of the circuits.Key words: Pass Transistors, Transmission Gate, Gate Diffusion Input, Power Dissipation, Self Adjustable Voltage Level circuit.

Strength of Welded Plate Girder with Tapered WebAbstract: As a result of the general acceptance of the optimum design concepts, slender and, in some cases tapered web is increasingly used in steel structures .These members will reduce dead weight of structure in tern material cost. Present research work is focusing on the determination of buckling strength and economy of tapered web. In the present study comparison is carried out between plate girder with uniform web depth and tapered web depth. Parametric studies with various geometries of tapered web plate were carried out to find the favorable and economical design situations. The present paper involves the finite element analysis of plate girder for different conditions like i) uniform web depth, ii) tapered web depth. The main comparison parameters are i) static behaviour, ii) buckling behaviour, iii) buckling strength. All models were analyzed using finite element based software ANSYS. At the end it is concluded that the tapered web plate has same buckling strength however it achieves economy.Key words: ANSYS, buckling strength, finite element, optimum design, tapered we Reference [1] Bedynek , E.

322. | Modified Distribution Network Using HVDS Techniques
Modified Distribution Network Using HVDS TechniquesAbstract: This paper presents the comparison of existing low voltage distribution system with proposed high voltage distribution system. The study is based on a real low voltage feeder in J&K state. The investigation is carried out to determine the losses in the existing low voltage (LT) distribution system and then converting this low voltage distribution system to proposed high voltage distribution system (HVDS) including bifurcation of load and replacing the one large transformer with various transformers of small rating. Since loss reduction in distribution system is of keen importance and main reason behind these losses is the use of low voltage for distribution in existing system. As for the low voltage in existing distribution system, current is high which leads to high power losses and also allow the hooking and hence power theft. This paper aims at reducing losses by using LT less or less LT 'HVDS' system and then determining the reduction in losses in terms of units and annual savings in terms of rupees due to proposed method. To check the feasibility of the proposed work, the annual saving and payback period of the proposed method is also determined.Key words: Annual saving, Capital outlay, Distribution losses, High Voltage Distribution System, Payback period.

323. | The Use of Optical Remote Sensing For Mapping Flooded Areas
The Use of Optical Remote Sensing For Mapping Flooded AreasAbstract: Flood maps are a crucial tool to support emergency management, disaster recovery and risk reduction planning. Traditional flood mapping methods are time-consuming, labor intensive, and costly. Our goal in this paper is to introduce a novel technique to aggregate knowledge and information to map coastal flooded areas. We proposed a Difference of Normalized Difference Water Indices (DNDWI) derived from two LANDSAT-5/TM surface reflectance product acquired before and after the passage of Hurricane Ike, for Upper Texas in September of 2008. The reference flooded area was delineated interpolating the maximum surge in each location using a spline with barriers method with high tension and a 30 meter Digital Elevation Model (DEM). It was noticed that NDWI values decreased after the hurricane landfall on average from 0.226 to 0.122 for flooded area. However for the non-flooded areas it increased from 0.292 to 0.300. Results from the Monte Carlo simulation showed that mapping flooded areas with DNDWI got an accuracy of 85.68% while the non-flooded areas got an accuracy of 92.13%. Thus, DNDWI is promising tool for mapping flooded areas since it is a cheaper and simple technique which can be applied rapidly for several areas of the planet.Key words: Flood mapping, Hurricane, Monte Carlo Simulation, NDWI, Optical Remote Sensing Reference [1] N.

An Image Segmentation to Detect Tumor and Measuring Size of Tumor Using Segmentation of MR ImageAbstract: Medical image segmentation is the research focus in the medical image processing field. Detection of tumor requires image segmentation. The segmentation of tissues and tumors in magnetic resonance images has been an emerging field in research. There are several techniques used for tumor detection using MR image segmentation. This paper presents a segmentation algorithm to MR image which is able to detect the tumor in the MR image and also able to measure the size of the segmented image for treatment planning. First, an input image is converted into fixed size then preprocessed by Gaussian law pass filter which improve the quality of an image. Then the image is segmented using the thresholding method in which by selecting the threshold value an image is segmented. Then using region of interest the segmented image is cropped and then after measuring the size of segmented image using pixels for the treatment planning. And also there is post processing for morphological operations. This algorithm is much simpler and less complex in the calculation.Key words: Gaussian law pass filter, thresholding, Region of interest (ROI), erosion and dilation.

Application of Quality Function Deployment in an Engineering College Using Analytical Hierarchy ProcessAbstract: Quality Function Deployment (QFD) technique as a TQM tool, has found wide applications in manufacturing as well as service industries. However its application and practice in educational institutes is still not popular. This paper based on the study in an engineering college is an attempt to demonstrate and encourage the application of QFD for planning and improvement of quality to gain competitive edge by satisfying student needs. The responses of 329 students and 35 faculties were obtained through a questionnaire. Importance ratings for student needs were calculated using AHP and pair wise comparison. These ratings were used for construction of relationship and correlation ship matrices and construction of HOQ. Goals for each customer requirements (CR) and technical requirements (TR) were set after competitive assessment of four other local colleges. All the four phases of QFD from planning to design, delivery and control were constructed. The outcomes of each HOQ suggest "How's" for each "What" and the importance rating for each of them, which can be used for reforming the quality of engineering education in the college under study.Key words: Quality Function Deployment, Customer's (Students/Faculty) Need Analysis, Prioritization of CR, House of Quality Reference [1] Anil R Sahu et al [2008], Key Factors affecting the effectiveness of Technical Education- An Indian perspective, Proceedings of the World Congress on Engineering, Vol II, July 2-4, 2004 UK.

331. | A Hardware FPGA Implementation of Adaptive Stegano Analysis Using LSB Technique
A Hardware FPGA Implementation of Adaptive Stegano Analysis Using LSB TechniqueAbstract: This paper deals with the detection of hidden bits in the Least Significant Bit (LSB) plane of a natural image. The mean level and the covariance matrix of the image, considered as a quantized Gaussian random matrix, are unknown. An adaptive statistical test is designed such that its probability distribution is always independent of the unknown image parameters, while ensuring a high probability of hidden bits detection. This test is based on the likelihood ratio test except that the unknown parameters are re-placed by estimates based on a local linear regression model. It is shown that this test maximizes the probability of detection as the image size becomes arbitrarily large and the quantization step vanishes. This provides an asymptotic upper-bound for the detection of hidden bits based on the LSB replacement mechanism. System is developed on Xilinx Spartan3 Field Programmable Gate Array (FPGA) device using embedded development kit (EDK) tools from Xilinx.Key words: Adaptive detection, information hiding,, FPGA, EDK, Micro Blaze.

332. | An Efficient Searching Technique by Colonization of Random Data Set Based On Dynamic Programming
An Efficient Searching Technique by Colonization of Random Data Set Based On Dynamic ProgrammingAbstract: The logarithmic behavior of Binary Search to find elements requires data set to be arranged in ascending or descending order. This paper introduces the concept of data colonization which means naturally ordered sub-sequences are grouped together to become a data colony so that any type of searching technique could be applied to any ordered sub-sequence independently. Addresses of the colonies i.e. starting and ending of colonies are remembered by using the concept of memorizations from dynamic programming. We have run different searching techniques in different colonies on the basis of the size of the colony and results are satisfactory after comparing with sequential search. As we keep on increasing the size of the colonies by decreasing the colonizational density of data set, the hybrid memorized technique starts showing more logarithmic behavior rather linear even the list is not arranged.Key words: Colonization, Complexity, Dynamic programming, Memorization, Hybrid approach Reference [1] T.

333. | Dielectric Properties of Copper Substituted Nickel Nano-Ferrites
Dielectric Properties of Copper Substituted Nickel Nano-FerritesAbstract: Mixed Ni1-X CuX Fe2 O4 (0 ≤ X ≥ 1) nano-ferrites have been synthesized by Citrate-gel auto combustion technique. The structural characterization was carried out by X-Ray Diffractometer (XRD) and the crystallite size was found to be in the range of 36- 58nm. The dielectric properties such as Dielectric constant (ε'), Dielectric loss tangent (tan δ) and AC conductivity (σac) were studied at room temperature as function of frequency in the range 20Hz – 2MHz. The real part of dielectric constant (ε') and dielectric loss tangent (tan δ) showed a decreases with the increase in frequency where as the ac conductivity (σac) increases with increase in frequency. The dielectric constant (ε') shows an increasing trend with increase of Cu substitution in Ni nano-ferrites.Key words: Nano - Ferrites; Citrate-Gel Technique; X-Ray Diffraction; Dielectric Properties Reference [1] K.

334. | Angiotensin Converting Enzyme Genotype Prevalence among Egyptian Primary Nephrotic and End Stage Renal Diseases Patients
Angiotensin Converting Enzyme Genotype Prevalence among Egyptian Primary Nephrotic and End Stage Renal Diseases PatientsAbstract: The Renin-Angiotensin system (RAS) is a key regulator of both blood pressure and kidney functions and their interaction. In such a situation, genetic variability in the genes of different components of RAS is likely to contribute for its heterogeneous association in the renal disease patients. Angiotensin converting enzyme-1 (ACE-1) is an important component of RAS which determines the vasoactive peptide Angiotensin-II. In the present study, we have investigated 103 end stage renal diseases (ESRD), 104 primary nephrotic (P.N) patients and 102 normal healthy controls from Mansoura city in Egypt to deduce the association between ACE gene polymorphism and ESRD, P.N.The selected samples were assayed for genotyping of ACE I/D by (PCR) based DNA amplification using specific flanking primers. The results revealed that there was a significance distribution in DD genotype between ESRD and control group(p<0.05), with risk value (OR>1) which resulting in increasing the risk for ESRD.There was significance distribution in ID genotype between ESRD and control group (p<0.05), without disease risk (OR <1). Based on these observations we conclude that ACE DD genotype implicate a strong possible role in the in renal damage among Egyptians. The study will help in predetermining the timing, type and doses of therapy for ESRD patients.Key words: Angiotensin converting enzyme-1; end stage renal diseases; primary nephrotic; gene polymorphism.

335. | Data Mining Tool using Clustering Technique on Exploration Engine Dataset
Data Mining Tool using Clustering Technique on Exploration Engine DatasetAbstract: It is a major issue to retrieve good websites from the larger collections of websites. As the number of available Web pages grows, it is become more difficult for users finding documents relevant to their interests. Clustering is the classification of a data set into subsets (clusters), so that the data in each subset share some common trait - often proximity according to some defined distance measure. By clustering we improve the quality of websites by grouping similar websites in groups. This paper addresses the applications of data mining tool Weka by applying k means clustering to find clusters from huge data sets and find the attributes that govern optimization of search engines. Unlabeled document collections are becoming increasingly common and mining such databases becomes a major challenge.Key words: Websites; Data mining; Weka; k-means, Dataset.
