| 1. | Routing Protocol Performance Issues and Evaluation Considerations in MANET
Routing Protocol Performance Issues and Evaluation Considerations in MANETAbstract: Mobile nodes in Wire less a d-hoc networ k need to operate as routers in or d er to maintain the informa tion ab out network connectivity as there is no centralized infrastructure. Therefore, Routing Protocols are required which could adapt dynamically to the changing topologies and works at low data rates. As are sult, there arises a need for the compreh ensive performance evaluation of the ad-doc routing protocols in same frame work to under stand their comparative merits and suitability for deployment in different scenarios. In this paper the protocols suite selected for comparison are AODV, DSR, TORA and OLSR ad- hoc routing protocols, as these were the most promising from all other protocols. The performance of these protocols is evaluated through exhaustive simulations using the OPNET Model network simulator under different parameters like routing over head, delay , throughput and network load under varying the mobile nodes .Key words: MRAC, Ad-hoc Networks, AODV, DSR, TORA, OLSR, OPNET.

| 2. | A review of recent developments in national spatial data infrastructures (NSDI)
A review of recent developments in national spatial data infrastructures (NSDI)Abstract: Spatial Data Infrastructure (SDI) is the geographic data framework implementation of data, metadata, users and tools in terms of data infrastructure that are connected in interactive way to allow the flexibly and efficient use of the data. The SDI has different components which work together to make the whole system function properly. The components of the SDI have been defined by Federal Geographic Data Committee (FGDC): Framework, Metadata, Standard, Partnership and Geo-data. People were added to SDI because of their importance as the decision makers, and they make final decisions together with the people defined in the partnership component. In this article, basic definitions were explored for different components in terms of rules, organizations and needs; which can be quite useful for countries that are still in the early stage of creating a National Spatial Infrastructure design.Key words: NSDI, Data, Metadata, Clearinghouse, Standard, Partnership,Geo-data Reference [1] Al Shamsi, S.

| 5. | The Wholesale Price Contract Under The Framework Of Fairness-Preferencing Nash-Bargain In A Two-Level Supply Chain
The Wholesale Price Contract Under The Framework Of Fairness-Preferencing Nash-Bargain In A Two-Level Supply ChainAbstract: The paper establishes a fairness preference framework based on game theory of Nash bargaining, and builds a utility system about fairness preference. On the basis, we expeands the newboy model to behavior research. The analysis shows that because of the retailer and suppliers' fairness preference, their optimal order quantities tend to became conservative, and the result shows that the greater the retailer's fairness preference, the smaller the optimal order quantity of the retailer and the supply chain system, and the change tendency of the supply chan is more obvious than that of retailer. the greater the supplier's fairness preference, the greater the optimal order quantity of the retailer and the supply chain system, and the change tendency of the supply chan is more obvious than that of retailer. Furthermore, we draw a conclusion that the wholesale price contract don't change the supply chain coordination. Finally, we make the sensitivity analysis of the wholesale price, the retail price, the manufacturing cost of supplier, the stortage cost of retailer and the stortage cost of supplier.Key words: Nash bargaining; newboy model; fairness preference; supply chain coordination; wholesale price contract Reference [1] J SPENGLER, Vertical integration and antitrust policy, Journal of Political Economy, 58(4),1950,347-352.

| 7. | Performance comparison of AOMDV and POR Routing Protocols in MANETS
Performance comparison of AOMDV and POR Routing Protocols in MANETSAbstract: Mobile ad hoc network (MANET) [1] is Mobile nodes that are communicated with each and every other hop using multi-hop wireless nodes. Each node acts as a router in network and no fixed infrastructure for mobile nodes and there is no base station of it, forwarding data packets for other nodes [2]. Without network infrastructure is known as ad hoc network is formed by mobile stations inside a restricted area which communicates without the need of access point [3]. An ad hoc network can be formed by mobile computers with wireless interfaces that are communicate among themselves without any help of infrastructure. In an ad hoc network the mobile nodes are access to serve both routers and hosts. Performance comparison of AOMDV and POR with ns-2 (version 2.34) simulations shows that throughput as POR packet delivery is better than that of AOMDV.Key words: MANETS, AOMDV, POR, Data delivery, routing protocol.

BREADFRUIT STEM ASH AS A PARTIAL REPLACEMENT OF CEMENT IN SANCRETE BLOCK MAKINGAbstract: Sandcrete blocks are the most widely used materials for walling units in Nigeria. This study investigated the use of breadfruit stem ash (BFSA) as a partial replacement of cement in sandcrete block making. The breadfruit stem ash was burnt using a local burner and analysis was carried out on the chemical and physical properties of the ash. Four blocks each (150x150x150 mm) were cast at 0%, 5%, 10%, 20%, 25%, 30%, 40% and 50% replacement levels. The cubes were crushed at 7, 28, and 48 days of curing. The results show that the compressive strength varied from 1.5N/mm2 to 6.5N/mm2 for the replacement levels at 48 days of curing. The 50% to 20% replacement levels displayed very low compressive strengths which were between the ranges of 1.5N/mm2 and 2.1N/mm2.Key words: pozzolans, breadfruit stem ash, compressive strength, curing, sandcrete, partial replacement.

| 14. | Face Recognition Using Moments and Wavelets
Face Recognition Using Moments and WaveletsAbstract: The field of face recognition has been explored a lot and the work is still going on. In this paper we have proposed a novel approach for face recognition using moments. Four feature extraction methods have been used: Hu moments, Zernike moments, Legendre moments and Cumulants. Hu moments include a set of seven moments which are derived from the conventional geometric moments. These moments are invariant against rotation, scaling and translation. Legendre and Zernike moments have an orthogonal basis set and can be used to represent an image with minimum amount of information redundancy. These are based on the theory of orthogonal polynomials and can be used to recover an image from moment invariants. Cumulants are sensitive to image details and therefore are suitable for representing the image features. For feature extraction, moments of different orders are calculated which form the feature vectors. The feature vectors obtained are stored in the database and are compared using three different classifiers. In case of cumulants, we have calculated the bispectrum of images and compressed it using wavelets.Key words: Bispectrum, Biwavelant, Face Recognition, Moments, Wavelets, Reference [1] R.

Technological Emergency Planning Through An Ontology Oriented ApproachAbstract: Having access to the right information before and during an industrial emergency could save organizations and keep them safe and sustainable. Accident databases among other are used to provide such accesses. But, usual accident databases are lacking to provide enough emergency knowledge. This paper tries to improve the current process accident databases information retrieval through developing a process accident knowledge base (PAKB). Technological accident concepts and subconcepts were identified. Then, the relevant taxonomy for each concept was developed and the relationships among all concepts were formalized. This collection was transferred into the protégé software for more formal interpretation and representations. The established PAKB could improve information retrieval processes, reduce query time and fault results. Despite customary databases, it can disclose the hidden relations among different stored data. The accident knowledge base imagines knowledge epresentation and concept relationships that could help to understand the hidden relations among the needed data. Such features are vital in the emergency management.Key words: Databases, knowledge base, Emergency management, Process Accident, Emergency Plan Reference [1] Batres, R., Muramatsu, H., Shimada, Y., Fuchino, T., & Chung, P.

Performance analysis of semiconductor optical amplifier using four wave mixing based wavelength Converter for all Optical networks.Abstract: In this paper, investigations are made on performance analysis of the semiconductor optical amplifier (SOA) using four wave mixing (FWM) based wavelength converter. This analysis is done at 10Gb/s in terms of shifted wavelength conversion efficiency, quality factor (Q-parameter) and bit error rate (BER) for up and down conversions. The investigations are carried out by varying the probe signal wavelength and bias current of SOA. From the numerical simulations it has been observed that down-conversion efficiency is more than Up-conversion efficiency and it starts decreases at larger wavelengths. It is found that maximum FWM conversion efficiency is around 27.3417 dB at current 160 mA and 28.5669 dB at current 160 mA for up and down conversion respectively for 10Gb/s.Key words: FWM, XGM, XPM, SOA, Wavelength conversion, Conversion efficiency..

Performance analysis of bi-directional broadband passive optical network using travelling wave semiconductor optical amplifierAbstract: In this paper performance analysis of a bi-directional broadband passive optical network (BPON) for both downstream and upstream traffic by using travelling wave semiconductor optical amplifier (TSOA) is carried out in terms of bit error rate (BER). The system has been analyzed on the basis of drive current of TSOA, data rate, fiber length, coding technique, number of users. From the simulation it has been observed that as we increases the no. of users, fiber length, data rate bit error rate is increasing due to optical pulse brodening and dispersion. It is found that value of bit error rate 3.65089x10-035 is more acceptable for drive current 0.27A at 20 km. From the investigations it has been found that system performance is better for NRZ modulation format than RZ format because NRZ coding is more tolerable to optical dispersion than RZ coding.Key words: Passive optical network (PON), Broadband passive optical network (BPON), Bit error rate (BER), Travelling wave semiconductor optical amplifier (TSOA).

Improving the implementation of new approach data privacy preserving in data mining using slicingAbstract: Several anonymization techniques, such as generalization and bucketization, have been designed for privacy preserving microdata publishing. Recent work has shown that generalization loses considerable amount of information, especially for high dimensional data. Bucketization, on the other hand, does not prevent membership disclosure and does not apply for data that do not have a clear separation between quasi-identifying attributes and sensitive attributes. In this paper, we present a novel technique called slicing, which partitions the data both horizontally and vertically. We show that slicing preserves better data utility than generalization and can be used for membership disclosure protection. Another important advantage of slicing is that it can handle high-dimensional data. We show how slicing can be used for attribute disclosure protection and develop an efficient algorithm for computing the sliced data that obey the ℓ-diversity requirement. Our workload experiments confirm that slicing preserves better utility than generalization and is more effective than bucketization in workloads involving the sensitive attribute. Our experiments also demonstrate that slicing can be used to prevent membership disclosure.Key words: Privacy preservation, data anonymization, data publishing, data security.. Reference [1] C.

HDL Based Illumination Invariant highPerformance Face Detection SystemforMobile applicationsAbstract: Illumination variation is a big problem in face detection which usually requires a costly compensation prior to classification. To avoid this problem we are proposing a method for face detection irrespective of illumination variations. In this context the contribution of the work is twofold. First we introduce illumination invariant Local Structure Features for face detection. For an efficient computation we propose a Modified Census Transform which enhances the original work of Zabih and Wood [11]. Secondly we introduceanefficient face detection classifier for rapid detection to render high performance face detection rate.The Classifier structure is much simpler because we use only single stage classifier than multi-stage approaches, while having similar capabilities.Key words: FPGA, MCT (modified census transform), Adaboost algorithm, Bio id test, Yale test Reference [1] Dongil Han, Member, IEEE, Jongho Choi, Jae-Il Cho, and Dongsu Kwak "Design and VLSI Implementation of High-Performance Face-Detection Engine for Mobile Applications",2011 IEEE International Conference on Consumer Electronics (ICCE) [2] Paul Viola and Michael J.

Push Over Analysis of Tall Building with Soft Stories at Different LevelsAbstract: Open first storey is a typical feature in the modern multistory constructions in urban India. Such features are highly undesirable in buildings built in seismically active areas; this has been verified in numerous experiences of strong shaking during the past earthquakes. Though multistoried buildings with open (soft) ground floor are inherently vulnerable to collapse due to earthquake load, their construction is still widespread in the developing nations like India. Social and functional need to provide car parking space at ground level and for offices open stories at different level of structure far out-weighs the warning against such buildings from engineering community. With ground soft storey for office space open floor is required on different levels of building. In present thesis we are concentrating on finding the best place for soft stories in high rise buildings. With the availability of fast computers,Key words: PUSHOVER ANALYSIS.

Neighbor Node Discovery in Asynchronous Sensor NetworksAbstract: A sensor network may contain a huge number of simple sensor nodes that are deployed at some inspected site. In large areas, such a network usually has a mesh structure .In most sensor networks the nodes are static .Nevertheless ,node connectivity is subject to changes because of disruptions in wireless communication, transmission power changes, or loss of synchronization between neighbouring nodes. Hence, even after a sensor is aware of its immediate neighbours, it must continuously maintain its view, a process we call continuous neighbour discovery. In this work we distinguish between neighbour Discovery during sensor network initialization and continuous neighbour discovery. We focus on the latter and view it as a joint task of all the nodes in every connected segment. Each sensor employs a simple protocol in a coordinate effort to reduce power consumption without increasing the time required to detect hidden sensors.Reference [1] S. Vasudevan, J. Kurose, and D.

Performance Of Self Compacting Concrete By Using AlccofineAbstract: In Japan, in early eighties, premature deterioration of concrete structures were detected almost everywhere in the country. The main cause of the deterioration was recognized as inadequate compaction. In addition, the gradual reduction in the number of skilled workers in Japan`s construction industry led to a reduction in the quality of construction work. As a solution for these social and technical requirements, the concrete of SCC was proposed by Prof. Okamura at Tokyo University in 1988.Key words: Self Compacting Concrete, Alccofine, Compatibility, Strength Reference [1] Hardik Upadhyay, Pankaj Shah, Elizabeth George, Testing and Mix Design Method of Self –Compacting Concrete ,National Conference on Recent Trends in Engineering & Technology, May 2011 p [2] Iliana Rodriguez Viacava, Antonio Aguado dea Cea, Gemma Rodriguez de Sensale, "Self Compacting Concrete of medium concrete characteristics Strength."

Implementation Of Low Power SRAM By Using 8T Decoupled LogicAbstract: We present a novel half-select disturb free transistor SRAM cell. The cell is 6T based and utilizes decoupling logic. It employs gated inverter SRAM cells to decouple the column select read disturb scenario in half-selected columns which is one of the impediments to lowering cell voltage. Furthermore, "false read" before write operation, common to conventional 6T designs due to bit-select and word line timing mismatch, is eliminated using this design. Two design styles are studied to account for the emerging needs of technology scaling as designs migrate from 90 to 65 nm PD/SOI technology nodes. Namely we focus on a 90 nm PD/SOI sense Amp based and 65 nm PD/SOI domino read based designs. For the sense Amp based design, read disturbs to the fully-selected cell can be further minimized by relying on a read-assist array architecture which enables discharging the bit-line (BL) capacitance to GND during a read operation. This together with the elimination of half-select disturbs enhance the overall array low voltage operability and hence reduce power consumption by 20%–30%.Key words: Column-decoupled, differential/domino read, half-select, low power 8T, SRAM, stability.

Providing Fair Transmission Opportunity By Detecting And Penalizing Malicious Stations In IEEEE 802.11e EDCA WLAN And Analyzing The Performance Of IEEE 802.11eAbstract: IEEE 802.11e Medium Access Control (MAC) is an enhancement to the Wireless Local Area (WLAN) IEEE 802.11 standard to support QOS.IEEE 802.11e is used which enables QOS to various delay sensitive applications such as voice, video over WLAN and Streaming multimedia. In this paper we proposed a Malicious Behavior Detection Algorithm that allows identification of misbehaving wireless stations and give out punishment by not sending an Acknowledgment (ACK) packet by the malicious stations and analyze the performance of IEEE 802.11e. This algorithm is designed for an IEEE 802.11e network and is based on detecting a QOS change where a station is moved to a level which is not justified based on the parameters such as TXOPLimit, AIFS and Backoff time. Our strategy is to provide fair resource sharing between the stations which are operating from the same access point and to provide QOS by provisioning the priority to different classes of traffic and make sure that always higher prioritized traffic gets preferential access to channel than lower prioritized traffic.Key words: IEEE802.11, IEEE802.11e, QOS, Malicious Station, Transmission Opportunity, EDCA, MAC, WLAN Reference [1] Prof. Rathnakar Acharya, Dr. V.

| 34. | RF Filter Design Using Insertion Loss Method And Genetic Optimization Algorithm
RF Filter Design Using Insertion Loss Method And Genetic Optimization AlgorithmAbstract: A filter design using insertion loss method (ILM) and Genetic Algorithm (GA) is presented in this paper. Many techniques have been proposed for the design and analysis of filter circuit, but the insertion loss method is generally preferred for the flexibility and accuracy that it provides. The ILM is based on network synthesis techniques and can be used to design filter having a specific type of frequency response. However, this procedure is not practical for a large number of elements. GA algorithm can be a useful procedure for calculating values in filters with a large number of elements. This paper presents the procedure which takes an advantage of ILM for filter design and GA for determination of an unknown value in filters with large number of elements. This is suitable approach for filter design with an arbitrary shape of cutoff frequency and pass band.Key words: Genetic Algorithm, insertion loss method, RF filters Reference [1] Juraj Palecek, Martin Vestenicky, Peter Vestenicky, Dasa Ticha, "Optimization of RF Band Pass Filter by Genetic Algorithm", 978-1- 4673-1179-3/12/$31.00 ©2012 IEEE, pp. 79-82.

Reduction Of Common Mode Voltage In Ac Drives Using Multilevel InverterAbstract: In this paper, an approach to reduce common-mode voltage (CMV) at the output of multilevel inverters using a phase opposition disposed (POD) sinusoidal pulse width modulation (SPWM) technique is proposed. The SPWM technique does not require computations therefore, this technique is easy to implement online in digital controllers. A good tradeoff between the quality of the output voltage and the magnitude of the CMV is achieved in this paper. This paper realizes the implementation of a PODSPWM technique to reduce CMV using a fivelevel diode clamped inverter for a three phase induction motor. Experimental and simulation results demonstrate the feasibility of the proposed technique.Reference [1] Yoshihiro Murai, Takehiko Kubota, and Yoshiriro Kawase, "Leakage current reduction for a high-frequency carrier inverter feeding an induction motor," IEEE Trans.

Finite Element Analysis of Reinforced Concrete Column Under Lateral LoadAbstract: To serve its purpose a structure must be safe against collapse and serviceable in use. Serviceability requires that deflections be adequately small to keep the cracks within tolerable limits. Although the widely followed ACI Code suggests a detailed method of deflection calculation, it often cannot exactly perceive the actual behavior of a structure. For this purpose, finite element analysis, using ANSYS, was performed. The research aimed of developing a program for the analysis of a column fixed at base and observes lateral deflection. Concept of key point, nodes, meshing and separate elements was used to model the concrete and the reinforcement. The scope of the study is limited to lateral load only applied at the midpoint at the top height in X direction. The same operation can also be performed in Y direction. The current application facilitates using random size of column with random height. But to serve the purpose of a single story, the work was done considering only one story height.Key words: finite element, key point, lateral load, mesh, nodes Reference [1] Pfrang, E.O. and Siess,C.P.

In this paper, we consider the collision attack that can be easily launched by a compromised (or hostile) node: a compromised node does not follow the medium access control protocol and cause collisions with neighbor transmissions by sending a short noise packet. This attack does not consume much energy of the attacker but can cause a lot of disruptions to the network operation. Due to the wireless broadcast nature, it is not trivial to identify the attacker. This paper describes detection algorithms for wireless sensor networks, which detects collision attack based on the packet flow rate to base station node in the network. Simulation results show that the algorithms have low false toleration and false detection rates and small time to detect attacks.Key words: wireless sensor network, packet flow, cluster topology, collision attack Reference [1] Zhenwei Yu, Jeffrey J.P.

Strength Comparison of Ordinary Portland Cement And Rice Husk AshAbstract: Rise husk ash is one of the promising pozzolanic materials that can be blended with Portland cement for the production of durable concrete. Addition of rise husk ash to Portland cement not only improve the strength of concrete but also forms the calcium silicate hydrate gel around the cement particles which is highly dense and less porous. This may be increase the strength of concrete against cracking. Thus in the present investigation a realistic approach has been made using different techniques such as compressive strength, bond strength, split tensile strength etc. using different percentage of RHA and varying curing periodKey words: Pozzolanic material, RHA (Rice Husk Ash).

This method offers the ability to non-intrusively identify resources that have available CPU cycles; this is critical for lowering queue wait times in large cluster grid networks. The benefits include: 1) low message complexity, which facilitates low latency in distributed networks, 2) scalability, which provides support for very large networks, and 3) low maintainability, since no additional software is needed on compute resources.Key words: MRAC, Induction Motor drive, drift and saturation Reference [1] P.

Recognizing English Grammar Using Predictive ParserAbstract: We describe a Context Free Grammar (CFG) for English language and hence we propose a English parser based on the context free grammar. Our approach is very much general to apply in English Sentences and the method is well accepted for parsing a language of a grammar. The proposed parser is a predictive parser and we construct the parse table for recognizing English grammar. Using the parse table we recognize syntactical mistakes of English sentences when there is no entry for a terminal in the parse table. If a natural language can be successfully parsed then grammar checking from this language becomes possible. The proposed scheme is based on Top down parsing method and we have avoided the left recursion of the CFG using the idea of left factoring.Key words: Context Free Grammar (CFG), Predictive Parser, Parse Table, Top down and Bottom up Parser, Left Recursion Reference [1] K.

Exhaust Gas Analysis of SI Engine and Performance Of Catalytic ConverterAbstract: Exhaust system, the least concerned section by the people has the most effective role on the environment as it is that portion of an automobile through which exhaust gases get out from the combustion chamber to pollute the air by their contaminated contents. The exhaust system components like catalytic converter, muffler and resonator make it possible to let out the least possible contaminated gas from the engine exhaust manifold. The performance of the emission control system particularly by the catalytic converter and the noise control are the main concern of this paper. To make a comparison of the exhaust gas emission providing with catalytic converter or not, an exhaust gas analyzer was used to collect experimental data. All the experimental data and graphical representation concludes that the carbon content in the exhaust gas from the car, Toyota E-90 has been reduced to a great extent with the help of catalytic converter & the noise has been reduced as well for the proper attachment of muffler in exhaust system.Key words: Exhaust system, Catalytic converter, Substrate, Catalyst, Muffler, Noise control.

The first, associated resource impact costs, deals with the costs that arise when failure in one machine impacts on the productivity and cost effectiveness of other machines working in close association with it. The second category, lack-of-readiness costs, addresses the cost that may be incurred when a capital asset is rendered idle by the downtime resulting from a prior failure. The third cost category, service level impact costs, deals with the situation that arises when one machine in a pool of resources fails to the extent that other machines in the pool must work in an uneconomical manner to maintain a given service level.Key words: Equipment Downtime Cost, Downtime cost.

Experimental Study on Enhancement Of Thermal Performance Of Wire Wound Tube In Tube Helical Coil Heat ExchangerAbstract: Present work experimentally investigates the hydrodynamic and heat transfer analysis of three different geometries of the tube in tube helical coil. This study was conducted over a range of Reynolds numbers from 2500 to 6700 using cold water in annulus side. The experiments were carried out in counter flow configuration with hot water in tube side and cold water in annulus side. Each patterned coils were fabricated by bending 3.5 m straight mild steel tube having 10 mm ID and 12 mm OD, and stainless steel tube having 23 mm ID and 25 mm OD in four active helical turns having zero pitch with coil diameter 270mm. The mild steel wires of 1.5 mm were wound on outer side of inner tube having 6 mm and 10 mm pitch distance. The annulus side Nusselt number and friction factor were determined. The pressure drop and overall heat transfer coefficient is calculated at annulus side for different rate conditions. The results show that the 6 mm wire wound tube in tube helical coil have more overall heat transfer coefficient than that of 10 mm and plain tube helical coil.Key words: Tube in tube helical coil, wire wound, Nusselt number, Reynolds number, Reference [1] Alberto Garcı´a a,, Pedro G.

A Genetic Algorithm Based Approach For Optimization Of Test Time And TAM Length For 3D SoC Considering Pre-Bond Test Under The Constraint On The Number Of TSVsAbstract: Core-based system-on-chips (SoCs) fabricated on three-dimensional (3D) technology are emerging for better integration capabilities. Effective test architecture design and optimization techniques are essential to minimize the manufacturing cost for such giga-scale integrated circuits. Test-access mechanisms (TAMs) and test wrappers (e.g., the IEEE Standard 1500 wrapper) facilitate the modular testing of embedded cores in a core-based system-on-chip (SoC). Such a modular testing approach can also be used for emerging three-dimensional integrated circuits based on through-silicon vias (TSVs).This paper presents a Genetic algorithm(GA) based solution to Co-optimize test scheduling and TAM length for 3D SoC. A locally optimal best-fit heuristic based bin packing algorithm has been used to determine placement of cores minimizing the overall routing cost. Experimental result on ITC'02 benchmark SoCs shows that the proposed method provides few better test time results compared to earlier work.Key words: Genetic Algorithm, Rectangle Packing, System-on-Chip, Test Access Mechanism, Through Silicon Via Reference [1] Brandon Noia, Krishnendu Chakrabarty and Yuan Xie, "Test-Wrapper Optimization for Embedded Cores in TSV-Based Three-Dimensional SOCs" 978-1-4244-5028-2/09/$25.00 ©2009 IEEE.

Dct Based Image Steganographic ApproachAbstract: Steganography is the art of invisible communication. Its purpose is to hide the very 8presence of communication by embedding messages into innocuous-looking cover objects. In today's digital world, invisible ink and paper have been replaced by much more versatile and practical covers for hiding messages – digital documents, images, video, and audio files. As long as an electronic document contains perceptually irrelevant or redundant information, it can be used as a "cover" for hiding secret messages.Key words: DCT,DCT-BIT4, Image stegnography Reference [1] S.

Production of Biogas by Using Food WasteAbstract: The current work focuses on the generating bio-gas from food waste produced by Mahendra Engineering College Canteen using anaerobic digestion process. Attempts have been made to optimize various parameters in order to determine the most favorable recipe for maximum biogas production from the digested food waste. The biogas yields have been determined using batch anaerobic thermophilic digestion tests for a period of 90 days. Characteristic oscillation was observed in the rate of methane production, which may be due to the presence of methylotroph population in the activated sludge, which uses methane as a carbon source for their growth. The total biogas generated in the system over the experimental period was the sum of methane and carbon dioxide. Biogas produced from the decomposition of food waste was a mixture of 76% methane and 24% carbon dioxide.Key words: Anaerobic Digestion, BOD, Biogas, Food Waste, Reference [1] BryerslD. and Mason e.A.

Design of Enhanced Power Gating Technique to Reduce Leakage Power and Ground Bounce Noise for CMOS ApplicationsAbstract: In CMOS integrated circuit design there is a trade-off between static power consumption and technology scaling. Leakage power accounts for an increasingly larger portion of total power consumption in deep submicron technologies. Recently, the power density has increased due to combination of higher clock speeds, greater functional integration, and smaller process geometries. As a result static power consumption is becoming more dominant. This is a challenge for the circuit designers. However, the designers do have a few methods which they can use to reduce this static power consumption. But all of these methods have some drawbacks. In order to achieve lower static power consumption, one has to sacrifice design area and circuit performance. In this paper, we propose a new method to reduce static power in the CMOS VLSI circuit using dual stack approach without being penalized in area requirement and circuit performance.Key words: dual stack approach, state saving technique, stack effect, dual V-th, static power reduction Reference [1] S.

Implementation of H.264 Decoder On Arm11 MpcoreAbstract: The power dissipation in embedded processor core is an important parameter while increasing the process performance. With the advent of VLSI technology and the latest tools to design system on chip, the complexity, design time and verification time can be reduced. To increase the total processor performance, both the multiprocessor and multi threading systems are used for any application.ARM overcomes such design issues faced in the industry for any application. In a Multiprocessor design, each processor can use the uni-processor power management techniques, such as clock gating, keeping the processor in standby mode and voltage and frequency scaling. But it also has the ability to turn entire processor off to save all their consumed power while still executing lower demanding application workloads. One of the applications considered in this paper is implementation of H.264 video decoding using ARM MP Core ARM11.In H.264 video decoding implementation, the computational standard is two or three times higher than that of H.263 and MPEG-4 standard. The complex parts of the decoder in H.264 are the operation of entropy coding and De-blocking filters in the decoder. The reduction in computational complexity an algorithm is implemented for H.264 decoder. It contains a group-based CA VLC decoding method for H.264 entropy code tables and de-blocking filter.Key words: H.264; CAVLC; De-blocking Filter;ARM11 Reference [1] Thomas wiegand "Overview of the H.264/AVC video coding standards", IEE Transactions on circuits and systems for video technology vol. 13 No. 7 July 2003.

Producing Lead-Free Copper Alloys for Plumbing Fittings; A Case Study of Nigerian TapsAbstract: Inclusion of lead in pipe fittings brings about good machinability, lubricity and filling of pores created after casting. The leaching of lead into drinkable water exposes people particularly children to harmful effects of lead. In view this, it is necessary to search for other elements that can eventually replace lead and offering the advantages provided by lead. Nigerian taps (Brass Tap1, Brass Tap 2 and Cast Iron Tap) were considered in the study and it was observed that the lead compositions are 2.14%, ~ 5.81% and 0.011% respectively. The first two taps have percentages of lead which is above the allowable value of 0.25% given by most of the regulatory bodies. This brings the urgent need to consider alternative elements to replace lead.Key words: Brass taps, Cast iron taps, Lead, Leaching, Pipe fittings Reference [1] Scott, S (2011) "Transitioning to no lead copper " ESI North America Farmingting Hills Michigan [2] Sharon, O.S (2008): "Drinking Water" University of Nebraska–Lincoln Extension Publications [3] Steve, D (2008) "Drinking Water: Lead "University of Nebraska–Lincoln Extension Publications Nebraska Department of Health and Human Services [4] Safe Drinking Water Act Amendments of (1986).

Image Steganography Using Block Level Entropy Thresholding TechniqueAbstract: Now days a lot of applications are Internet based and in some cases it is desired that the communication be made secret. The two most important aspects of any image based Steganographic system are the imperceptibility and the capacity of the stego image. In this paper, a novel Image Steganographic method using Block Level Entropy Thresholding Technique is proposed. This paper evaluates the performance and efficiency of using optimized Embedding tables within JPEG Steganography. After dividing cover image into 8X8 non overlapping blocks, DCT (Discrete Cosine Transform) is computed and based on Entropy Threshold (ET) scheme, these blocks are selected for information embedding decision. The secret message is hidden in the Valid Entropy Block of cover-image with its middle-frequency of the DCT coefficients. Finally, a JPEG stego-image is generated. DCT based Steganography scheme provides higher resistance to image processing attacks such as JPEG compression, noise, rotation, translation etc. we obtain that the proposed method has a larger message capacity, and the quality of the stego images of the proposed method is acceptable.Key words: Steganography, Discrete Cosine Transform (DCT), Data hiding, Entropy Thresholding, MSSIM.

Abstract: The thermal power plants are used to
generate power. The thermal power plants are
designed based on required conditions (like a
good quality of steam, pressure and temperature
of steam etc.), but actually inlet conditions are not
as per the designed conditions. In practical
situations, when power plants are installed there
are lots of constraints. This tends to reduce or
increase output power and heat rate of thermal
power plants. Due to these conditions, the
designed power and heat rate are never achieved.
Variations in the power outputs from plant are
always a matter of disputes. So the parameters
for power and heat rate are generated for
different conditions of condenser pressure, flow
rate of water through the condenser,
Temperature difference. On the basis of site
measurement and design data collection
performance of the Condenser unit can be
evaluated. These evaluations indicate that if
operating conditions vary, then power output and
heat rate also vary. This paper deals with the
factors or parameters which reduced the
efficiency of the condenser. |

Cost Effective Approach for Automatic Service Provider Selection in Cloud ComputingAbstract: In today's advanced age the reason for the high success of cloud computing can be easily understood. The present high tech generation demands huge amount of computing resources and processing power. Cloud computing with the help of pay as you use model provides an excellent solution to the above issue. Easy availability and cost effective nature further make cloud much more exclusive and popular than other traditional computing paradigms. However, as the popularity of cloud computing increases, the number of provider offering cloud services also increase expeditiously. Thus it becomes quite challenging for a user to select the best cloud manually. Wrong decision would harm both the consumer and provider as it would lead to wastage of money for a consumer and imperfect utilization of resources of a provider. Thus keeping the above issues in mind this paper proposes a framework that selects the best and the most profitable cloud for a given user.Key words: cloud computing, cost effective, Cloud Provider, Cloud consumer, service level agreement Reference [1] Lee Badger, Tim Grance , Robert Patt-Corner and Jeff Voas, Cloud Computing Synopsis and Recommendations, NIST Special Publication 800 (2012):146 [2] "Benefits of cloud computing | Queensland Government"http://mobiledevices.about.com/od/additionalresources/a/Cloud-Computing-Is-It-Really-All-That-Beneficial.htm" [online; accessed June 2013] [3] "Social Success - 10 Benefits of Cloud Computing -Salesforce.com UK" view-source:http://www.salesforce.com/uk/socialsuccess/cloud-computing/why-move-to-cloud-10-benefits-cloud-computing.jsp[online; accessed June 2013] [4] Preeti Gulia and Sumedha Sood, Comparitive analysis of present day clouds using service level agreements, To be published in International Journal of Computer Application, 26th June 2013 [5] "If It's in the Cloud, Get It on Paper: Cloud Computing Contract Issues (EDUCAUSE Quarterly)|EDUCAUSE.edu" http://www.educause.edu/ero/article/if-its-cloud-get-it-paper-cloud-computing-contract-issues [online; accessed June 2013] Preeti Gulia, Sumedha Sood |

The blood is considered to be Newtonian fluid. The analytical expression for velocity profile and flow rate are obtained. The velocity profile and flow rate for various values of Hartmann number and inclination angle have been shown graphically.

Test Vector Generation and Compression for Fault Detection Using NDR and RLE AlgorithmAbstract: N detect tests are of mostly used because of their ability to improve the defect coverage. An N-detect test set detects each fault by at least N different vectors. The main problem which limits their use is their size. Researchers have proposed some methods to generate N-detect tests, but not much work has been done on compacting them. Also, there is no minimum size estimate of an N-detect test set. Methods for multiple detects test generation usually produce fully specified test patterns. This limits their usage in number of application such as low power test and test compression. Larger test data size demands not only higher memory requirements, but also increase the testing time. Test data compression overcomes this problem by reducing the test data volume without affecting the overall system performance. So this work provides a systematic methodology for identifying large number of unspecified bits in a multiple detect test sets, for detecting multiple faults while preserving the original fault coverage and the size of the test set is reduced using run length encoding method.Key words: Automatic Test Pattern Generation (ATPG), Multiple faults, N-detect test set, Run Length Encoding (RLE), Test set compaction Reference [1] Stelios N.

Design of an Efficient 128-Bit Carry Select Adder Using Bec and Variable csla TechniquesAbstract: Design of area- and power-efficient high-speed data path logic systems forms the largest areas of research in VLSI system design. In digital adders, the speed of addition is limited by the time required to transmit a carry through the adder. Carry Select Adder (CSLA) is one of the fastest adders used in many data-processing processors to perform fast arithmetic functions. From the structure of the CSLA, it is clear that there is span for reducing the area and power consumption in the CSLA. This work uses a simple and efficient gate-level modification to drastically reduce the area and power of the CSLA. Based on this modification 8, 16, 32, 64 and 128-bit square-root CSLA (SQRT CSLA) architectures have been developed and compared with the regular SQRT CSLA architecture. The proposed design has reduced area and power as compared with the regular SQRT CSLA with only a minor increase in the delay. This work estimates the performance of the proposed designs in terms of delay, area are implemented in Xilinx ISE and Modelsim.Reference [1] Bedrij, O. J.,(1962), "Carry-select adder," IRE Trans.

Vibration Performance Evaluation of Collecting plates of Electrostatic Precipitators Using FEA ApproachAbstract: Electrostatic Precipitators is the device used for removal of dust from boiler process gases. Various factors affect the effectiveness of this device. One of them is regular cleaning of the collecting electrodes. The dust removal takes place due to vibrations of collecting electrodes. Further, in time bound project development, it becomes very difficult to test at every stage of design improvements which also affect the project cost. In such cases, more practical approach is to make design improvements through simulations followed by validation through physical measurements. This paper presents FEA approach for modeling and analysis of collecting electrodes in an electrostatic precipitator using Implicit transient dynamic analysis approach. Experimental testing is done for validation of results. The results of FEA approach and testing are discussed.Key words: Collecting electrodes, Electrostatic Precipitator, Experimental testing, FEA, Vibration analysis Reference [1] Andrzej Nowak, Vibration of collecting electrodes in electrostatic precipitators - Modelling, measurements and simulation tests, Journal of Electrostatics 70 (2012) 327e332 [2] Nowak Andrzej, Wojciech Stanisław, Optimisation and experimental verification of a dust-removal beater for the electrodes of electrostatic precipitators, Computers and Structures 82 (2004) 1785–1792.

Performance of BER in OFDM System Using Different Channels and Modulation TechniquesAbstract: OFDM system suffers significant performance, when transmitted over different channels. Various channels like AWGN , Rayleigh Fading channels were taken which can be used for the transmission of OFDM signals. Different modulation techniques like QPSK, BPSK, MSK can also be used to modulate the signal before transmission. So the performance of BER can be calculated when modulated by using different modulation technique and when passes through different channels [1]. In this paper, we derive approximate closed-form expressions for BER performance in AWGN channel with different modulation techniques like BPSK,QPSK,8-PSK,16-PSK,32-PSK modulations and predict the performance of bit error rate (BER) with respect to Signal Energy per bit over noise power density ratio (Eb/N0). Simulation results show that the proposed simple analytical forms are quite accurate for different modulation techniques , which lead to the conclusion that BPSK gives the best and ideal performance as compared to other PSK in wireless communicationsKey words: AWGN, BPSK, QPSK, 8-PSK, 16-PSK, 32-PSK, BER, OFDM Reference [1] IEEE Std 802.11a-1999, Supplement to IEEE standard for information technology - telecommunications and information exchange between systems - local and metroplitan area networks - specific requirements.

Computer Aided Selection of Robot for Loading and Unloading Operation by Multiple Attribute Decision Making (MADM) ApproachAbstract: The selection of a suitable robot is becoming more and more difficult because of the large increase in robot manufacturer, configuration and available option. In this work a methodology and programming algorithm, based on Multiple Attribute Decision Making is developed for such type of selection problem. TOPSIS (Technique for Order Preference by Similarity to the Ideal Solution) method is used to rank the available alternative. Weights are assigned by the decision maker to the different attribute according to their importance. This method will help the decision maker to select a suitable robot according to his requirement. The developed software is analysed by an illustrative example for loading and unloading operation with same data.Key words: Attribute, selection of robot, MADM approach, rank according to reqirement Reference [1] Zeshui Xu, "a method for multiple attribute decision making with incomplete weight information in linguistic setting", Elsevier Science Publishers, Vol.-20,Issue 8, 719-725 [2] R.

Green Energy and Green Buildings in EgyptAbstract: This paper addresses the current status and the potentials of energy efficiency and renewable energy applications in Egypt. The use of primary energy resources had increased while the primary energy demand and GDP had decreases in the last two years. Egypt economy uses more than 50% of final energy per GDP than other surrounding counties. Egypt has adopted various sets of measures that increase the role of renewable energy sources for supplying and substituting fossil energy. Egypt had started several projects which focus wind farm in the Suez Gulf Zone with high wind speeds which ranges between 8 – 10 m/s in average and also due to the availability of large un-inhabitant desert area. Over 60% of the total electricity consumption is attributed to residential, commercial and Governmental buildings. To improve the energy efficiency of buildings, three building energy codes were published for new residential [1], commercial [2]and Governmental [3] buildings. These codes estimate to improve the efficiency by about 20% of total Electricity consumed.Reference [1] Energy Efficiency Residential Building Codes, HBRC, 2005 [2] Energy Efficiency Commercial Building Codes, HBRC, 2009.

Effect Of Web Reinforcement On Ultimate Strength Of Reinforced Concrete Deep BeamAbstract: It is observed that, reinforced concrete beams failed due to flexure but in case of deep beam failure occur due to shear. Deep beams may be defined as the beam where shear span to depth ratio less than 2. A number of researchers already proposed various approach to predict the ultimate strength of deep beams. In this study a newer approach is developed to calculate the ultimate shear strength of deep beams based on strut and tie model. Deep beams of different web reinforcement are used to predict the shear strength. A new effectiveness coefficient has been introduced to understand the contribution of steel during failure of deep beam under concentrated loads.Key words: deep beam, shear strength, concrete strength.

Now a day water-magnetic abrasive machining is one of the new alternative concepts that the magnetic field (line of magnetic force) is used to precisely machine the surface of the work-piece. When it is a magnetic work-piece and the work-piece is magnetized and then become a new magnetic pole. On the country when it is non-magnetic it cannot be magnetized. In this research the precise processing phenomenon and the condition on abrasive machining of material by a high velocity of water and magnetic abrasive and other abrasive material whose hardness and grain size similar to magnetic abrasive are examined. And the final experiment result shows the comparison between effectiveness of the mixing of water and abrasive on the surface finish of the AISI 52100 steel materials.Key words: Optimization, Grey relational analysis, surface roughness, material removal rate.

Comparative Analysis of VANET Routing Protocols Using VANET RBC and IEEE 802.11pAbstract: The Vehicular Adhoc network is the emerging research area which makes a phrase 'Network on the wheel". VANET is a collection of communication vehicles to broadcast desired information. In this paper performance of three routing protocols namely Adhoc On Demand Distance Vector Routing (AODV), Destination Sequence Distance Vector (DSDV) and VANET Radio Broadcasting Protocol (VANETRBC) is compared for various parameters. Here, DSDV protocol is a table driven protocol while AODV is on demand protocol. VANETRBC is a general radio broadcasting protocol taken into consideration. To decide the protocols is a challenge as per author reference [1]. All these three protocols are compared with the help of IEEE 802.11p standard using NS-2.33(Network simulator – 2.33) as per author [12]. The main purpose of this paper is to focus on analysis and comparison of the routing protocols so that this will help researchers to add their contribution in the field of VANET.Key words: Routing protocols, simulation, VANET, Network Simulator, AODV, DSDV, VANETRBC Reference [1] Sweta Verma Sweta Verma* & Dr. Vivek Kumar**.

Development of the Self Compacting Concrete By Industrial Waste (Red Mud)Abstract: Self-compacting concrete (SCC) is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement. The hardened concrete is dense, homogeneous and has the same engineering properties and durability as traditional vibrated concrete. Due to industrialization there is huge amount of red mud created. Aluminum is now consumed during manufacture red mud, which is used. Red Mud is industrial waste and causing threat to environment so the reduce the cost of the construction also to make structure more durable, reduce problem of this material the project has been undertaken so that it can be used for construction fashion of the concrete by blending or by replacing the cement by Red mud.Key words: Self-compacting concrete, industrial waste, modified concrete Reference [1] Ouchi, M., M.

An Efficient Approaches For Privacy Preserving In Microdata Publishing Using Slicing and Partitioning TechniqueAbstract: Privacy preserving publishing is the kind of techniques to apply privacy to collected vast amount of data. The data publication processes are today still very difficult. Data often contains personally identifiable information and therefore releasing such data may result in privacy breaches; this is the case for the examples of micro data, e.g., census data and medical data. This paper proposed techniques to accelerate accessing speed of user as well as applying privacy to collected data. Several anonymization techniques were designed for privacy preserving data publishing. Recent work in data publishing has shown that generalization loses considerable amount of information, especially for high dimensional data. Bucketization, on the other hand, does not prevent membership disclosure.Key words: Data Publishing, Microdata, Generalization, Bucketization, Anonymization Reference [1] B.-C. Chen, K.

These location, in turn, need to keep sufficient stocks of multiple spares as a guard against the possibility of system/equipment remaining defunct until the spare is acquired from the central depot or outside supplier. Determination of optimum number of spares to be held at each location that attains the desired level of system/equipment availability is one issue, the spares procurement and provisioning policies with regard to safety stock, reorder level etc. is another.

Comparative Plucking Force Characterisation of Chicken Produced From Two Breeds of ChickenAbstract: The conversion of a live chicken into safe and wholesome meat products suitable for human consumption takes place in a series of processing steps. Few of the processes require force to carry it out successively among which are slaughtering and de-feathering. The latter is the focus in this paper, plucking force of chicken produced from two breeds of chicken. Each sample of the chicken carcass was loaded into the hanger and lowered into the rotary drum for plucking one at a time. The process took an interval of one minute from one temperature to another in order to determine the appropriate plucking force. The results obtained for plucking contour and down feather of local chicken carcass were 11.26N and 2.44N respectively at 85oC for 5 minutes. The corresponding values for the exotic breed carcass in the order listed above are 4.13N and 1.02N respectively at temperature of 70oC for 3 minutes. The results obtained showed that the two samples of chicken examined would meet-up with daily demand in relation to production rate domestically.Key words: Chicken, Contour, De-feathering, Down, Plucking-force.

The formation of layer was studied on samples of carbon steels, alloyed steel and of iron Armco. The results obtained showed that the chemical composition of phases in the developed layers is determined by the nature the saturated medium and not by the intensive concentration of boron in the medium. For the same conditions of saturation it is observed that the thickness of the layer increases with the reduction of the carbon content of steel. The mechanical characteristics, the corrosion resistance and the qualitative characteristics of the texture of the single-phase layer were also studied.Key words: Thickness of boride layer, micro hardness, brittleness, pole density, powder, saturating medium, scattering angle, single-phase layer, texture perfection.

Ubiquitous Embedded Systems Revolution: Applications and Emerging TrendsAbstract: This paper describes the various technological revolutions and pinpoints the embedded systems revolution as the most recent and quietest of all. Being a revolution within another, it is seen as embedded into digital revolution. Embedded systems came into limelight with the birth of microcontrollers and have invaded and embedded themselves into all fields of our lives and this ubiquity is increasing in our daily lives. Despite this, the level of awareness of embedded system is low, hence this paper is written. During the survey of embedded systems evolution the point that they perform dedicated functions was brought to the fore. Most embedded systems are encapsulated within the main working frame of the device being controlled. The widespread and diverse natures of the system as seen in the numerous applications confirm the revolution of this ubiquitous system.Key words: dedicated function, digital revolution, embedded system, microcontrollers, ubiquitous system Reference [1] http://en.wikipedia.org/wiki/Industrial_Revolution Industrial revolution, retrieved May 7, 2013.

Improvement of Voltage Profile through the Distributed Generation in Power System NetworkAbstract: The impending deregulated environment faced by the electric utilities in the twenty first century is both a challenge and an opportunity for a variety of technologies. The need to provide acceptable power quality and reliability will create a very favorable climate for the entry of distributed resources and innovative operating practices. Of all the different parts of an electric power system, customers identify closely with the distribution subsystem due to its proximity and visibility on a daily basis. Several recent developments have encouraged the entry of power generation and energy storage at the distribution level. A distributed utility will use both distributed resources and load management to achieve its goal. In addition, several compact distributed generation technologies are fast becoming economically viable.Reference [1] Ajay P., Vimal R. D., Senthil, Kumar S., Raja J.

Development of Equations for Estimating Energy Requirements in Processing Local Alcoholic Beverage (Burukutu) In NigeriaAbstract: Determination of the energy consumption in the processing of local alcoholic beverage, burukutu in selected commercially viable six (6) local government areas in Benue state of Nigeria was conducted. Eighteen cases were randomly investigated within these locations. Mathematical expression was developed to evaluate the energy requirement for each of the seven (7) readily defined unit operations, namely steeping (St), grinding (Gr), washing (W), mashing (M), filtering (Fl), boiling (B) and re-filtering (Re-Fl). The equations were exploited to compute energy expenditure in the production using measured input data. Empirical equation was developed for each unit operation to relate energy requirement to red sorghum input in kg. The application test of the equations indicated that about 3122.90MJ was averagely needed to process about 150 kg of red sorghum in each location while energy requirement for each unit operation in each location was also estimated. Results showed no significant difference at 95% confidence level of the energy requirements for the 18 cases studied with respect to the identified unit process of production.Key words: Beverage, burukutu, development, energy equation, requirement, empirical.

High Frequency 32/33 Prescalers Using 2/3 Prescaler TechniqueAbstract: Frequency synthesizer is one of the important element for wireless communication application. The speed of VCO and prescaler determines how fast the frequency synthesizer is. A dual modulus prescaler contains logic gates and flip-flops. To fulfill the need of high frequency and low voltage circuit suitable flip-flops must be selected. Four different classes of flip-flops like master-slave, pulse-triggered, differential and dual-edge triggered (DET) are analyzed. Higher clock load in pulse-triggered FF and switching on both side of clock cycle in DET made them unusable in practical design for prescaler circuits. Due to this reason dual-edge triggered and pulse-triggered flip-flops are not taken for the comparison. Divide-by-2/3 prescaler is implemented by TSPC, ETSPC master-slave and differential type of flip-flops. Different 32/33 prescalers are implemented by choosing various combinations of 2/3 prescaler and flip-flops. Prescalers using different FFs are compared in terms of operating frequency, power, delay and power-delay-product. The operations of prescalers are ensured in cadence virtuoso simulator under 180nm technology.Key words: D flip-flop (DFF), extended TSPC (ETSPC), frequency divider, operating frequency, power-delay-product (PDP), prescaler, stacked structure.

Transient Analysis of Wind Based-DFIGAbstract: Demand for wind power has increased considerably due to technological advances and favorable government policies. As a result, large wind farms with multi-megawatt capacity are connected to sub-transmission and transmission systems. With high penetrations of wind energy, performance of the overall system is affected by the technical impacts introduced by wind turbine generators (WTG). Fault current contributions from WTGs will have a significant impact on the protection and control of the wind farm as well as the interconnected system. This paper initially describes the modeling aspects of Doubly- Fed Induction Generator (DFIG) during steady state and faulty conditions. Vector decoupling control strategy has been adopted to establish the mathematical model of DFIG based wind generator. Further, a 9 MW wind farm with 6 units of 1.5 MW DFIG is modeled in Matlab/Simulink and, voltage and current waveforms are presented and discussed for 3- phase fault, phase to phase fault and phase to ground fault created at the generator terminal and close to MV bus.Key words: Decoupled control, doubly-fed induction generator, dynamic performance, mathematical modeling, wind power.br /> Reference [1] G.H.

Temperature Control System Using Artificial Neural NetworkAbstract: Artificial Intelligence (ANN) based controller for temperature control of a water bath system. The generation of membership function is a changeling problem for fuzzy systems and the rejoinder of fuzzy systems depends mainly on the membership functions. Artificial Neural Network based input and output used to tune the membership functions in fuzzy system. Two input and single output artificial intelligence is designed to control the temperature system .Further the tuning of controller parameters is difficult in PID because the overshoot and also time constant is large. Fuzzy controller does not require a priori model of process for implementation but the membership values are found by trial and error. A five layer neural network is used to adjust input and output parameters of membership function in a fuzzy logic controller. The hybrid learning algorithm is used for training this network .When compared with other controllers (PID and fuzzy controller), neural network shows a better performance achieved with its tuning. Finally, validity of this approach can be illustrated by practical implementation using LabVIEW.Key words: PID Controller, Fuzzy controller, Neural Network Controller, temperature control, hybrid learning.

Advanced Maximal Similarity Based Region Merging By User InteractionsAbstract: Image segmentation is a popular method for dividing the image into various segments so as to change the representation of an image into something that is more meaningful and easier to analyze[12]. This paper presents a new region merging based interactive image segmentation method. A novel maximal-similarity based region merging mechanism is proposed to guide the merging process with the help of markers in which the user only need to mark the object desired to be extracted. The sample image taken for analysis is initially segmented using multi level thresholding technique[1]. This technique is used as it provides very good segmentation results than any other method. The regions are merged based on the similarity criteria depending upon comparing the mean values of both the regions to be merged.Key words: Image Segmentation, MSRM, Multi level Thresholding, Euclidean distance.

Challenges to Open Access in Teaching at University of Dar Es Salaam (UDSM)Abstract: This paper offers a perspective on some of the challenges experienced with respect to taking advantage of open access materials in Higher Education in developing countries with particular reference to University of Dar Es Salaam (UDSM). It is evident that the widespread awareness and understanding of open access concepts should lead to higher utilization of these academic resources and may lead to an increase of the quality of publication, research and the quality of teaching and learning. To this end, some countries have opted to adopt open access policies. However, the challenges between countries might differ based on several factors some of which are: the differences between the education systems as well as diversity in sources of funding support, with less direct involvement by national government. The author suggests that much more experimentation with business models, educational systems, is needed before we can well understand the sustainability of open access, the models that can effectively support it, and to what extent.Key words: open access, policy, education, models Reference [1] Suber, P (2006) "Open Access Overview: Focusing on Open Access to Peer-Reviewed research Articles and their pre-prints" http://www.earlham.edu/~peters/fos/overview.html accessed April 2012.

Minutiae Extraction and Pruning Based Fingerprint Identification with Pattern Classification by Radial Basis FunctionAbstract: Minutiae feature extraction is one of the most popular techniques used for fingerprint identification with great degree of success. This paper focuses on the enhancement in the performance of an Automatic Fingerprint Identification System in terms of FMR (false matching ratio) and FNMR (false non matching ratio). To achieve good results and make the system effective it is important to extract the minutiae features accurately. An algorithm is developed for minutiae extraction from fingerprints with varying quality, preprocessing in the form of filtering, binarization and thinning is first applied on fingerprint images before they are evaluated. Improved fingerprint pattern is generated by developing a feature pruning algorithm and then classification is done by radial basis function network. This developed algorithm is capable of finding the correspondences between input pruned fingerprint pattern and the stored template pattern without resorting to exhaustive search. The result has been analyzed on the basis that whether the system accepting an intruder or rejecting an authentic person.br />Key words: Automatic Fingerprint Identification System, Minutiae feature extraction, Pruning, Radial Basis Function Network.

Saw Dust Ash as Partial Replacement for Cement in the Production of Sandcrete Hollow BlocksAbstract: This study investigates the use of Saw Dust Ash (SDA) as partial replacement for ordinary Portland cement (OPC) in sandcrete blocks. Some units of sandcrete hollow blocks were produced by partially replacing the cement content with 5% to 25% by weight of SDA, using vibrating block moulding machine. Sandcrete blocks without SDA serve as the control. The blocks produced were tested to determine their density, compressive strength and water absorption rate. The results indicated that compressive strength of sandcrete hollow blocks at 28 days are 2.16N/mm2, 1.94N/mm2, 1.64N/mm2, 1.59N/mm2,1.39N/mm2, and 1.25N/mm2 for Control, 5%, 10%, 15%, 20% and 25% SDA contents respectively. At 56 days, the compressive strength of blocks with 5% and 10% SDA replacement are 2.33N/mm2 and 2.04N/mm2 respectively, both of which surpassed the required standard of 2.00N/mm2 specified by the National Building Code (2006) for non-load bearing walls. It was concluded that only sandcrete blocks with up to 10% SDA replacement can be used for non-load bearing walls.Reference [1] Adesanya, D.A. and Raheem, A.A.

| 122. | Comparison of Converter Fed Pmbldc Drive Systems with and Without Snubber
Comparison of Converter Fed Pmbldc Drive Systems with and Without SnubberAbstract: Permanent Magnet Brushless DC Motor has become a popular electrical drive because of its advantages such as high efficiency, increased reliability, quick dynamic response and very low maintenance. Due to this competitive edge it has stirred a lot of interest in simulating a PMBLDC Motor and its associated drive system in a comparatively simple manner. This paper elaborates the proposal of developing an inverter fed drive system with and without snubber in the circuit. This said snubber contains a resistor and a capacitor, where in the resistor is parallel connected with a diode. The voltage increases exponentially however the capacitance cannot change instantly therefore the critical rate of the rise in voltage slows down. Since the capacitor stores the required energy the same output is obtained even for reduced input ultimately increasing the motor efficiency.Key words: BLDC, Converters, Snubbers, Matlab / Simulink.

| 124. | A Novel Approach for Prioritization of Failure modes in FMEA using MCDM
A Novel Approach for Prioritization of Failure modes in FMEA using MCDMAbstract: Failure Mode Effect Analysis (FMEA) is one of user friendly and handy tool available in the hands of the process industries to identifying and eliminating the potential failures in systems, processes and designing. In this FMEA method prioritization of the failure modes are based on Risk Priority Number (RPN). This RPN can be calculated by multiplying the scores of various risk factors and categorized as Severity(S), Occurrence (O) and Detection (D). This RPN method has been criticized for its several limitations. So this paper aims to eliminate the limitations present in the RPN based prioritization by integrating with the Techniques of Multi Criteria Decision Making(MCDM) Model by fusing Analytical Hierarchy Process (AHP) with Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE).This hybridization of MCDM methods will enhance the precision of prioritizing failure modes by eliminating the limitations of traditional FMEA. The technique AHP is used to determine the weights for each risk factor and PROMETHEE is used to prioritize the failure mode based on the weights of risk factors.Key words: AHP, FMEA, MCDM, PROMETHEE, RPN, S, O, D and Risk Assessment Reference [1] Chang, C.L., Liu, P.H., and Wei, C.C.

Improvement of Satellite Images Resolution Based On DT-CWTAbstract: Satellite images are being used in many fields of research. One of the major issues of these types of images is their resolution. In this paper, we propose a new satellite image resolution enhancement technique based on the interpolation of the high-frequency sub bands obtained by discrete wavelet transform (DWT) and the input image. The proposed resolution enhancement technique uses DWT to decompose the input image into different sub bands. Then, the high-frequency sub band images and the input low-resolution image have been interpolated, followed by combining all these images to generate a new resolution-enhanced image by using inverse DWT. In order to achieve a sharper image, an intermediate stage for estimating the high-frequency sub bands has been proposed.Key words: Discrete wavelet transform (DWT), interpolation, satellite image resolution enhancement, wavelet zero padding (WZP), Dualtree complex wavelet transform (DT-CWT).

Prediction Based Channel Selection for Cognitive Radio NetworksAbstract: This paper proposes a novel prediction based packet delivery combined with novel medium access control (MAC) scheme for multichannel cognitive radio (CR) ad hoc networks, which achieves high throughput of CR system while protecting primary users (PUs) effectively. In designing the scheme, we consider that the PU signal may cover only a part of the network and the nodes can have the different sensing result for the same PU even on the same channel. By allowing the nodes to use the channel on which the PU exists as long as their transmissions do not disturb the PU, the proposed MAC scheme fully utilizes the spectrum access opportunity.Key words: Security, CR networks, denial of sleep attack, ARIMA, SARIMA Reference [1] S.

Stateless Multicasting In Ad-Hoc Networks Guided By Motion EstimationAbstract: Multicast routing protocols typically rely on the a priori creation of a multicast tree (or mesh), which requires the individual nodes to maintain state information. In sensor networks where traffic is bursty, with long periods of silence between the bursts of data, this multicast state maintenance adds a large amount of overhead for no benefit to the application. Thus, Chen-Hsiang Feng et al. have developed a stateless receiver-based multicast protocol that simply uses a list of the multicast members (e.g., sinks), embedded in packet headers, to enable receivers to decide the best way to forward the multicast traffic.Key words: Ad-Hoc, MANET, multicast routing protocols, RBMulticast, stateless.

Fuzzy Scheduling For Ensuring Qos in VMAC for VANETsAbstract: The need of a medium access control (MAC) protocol for an efficient broadcast service is of great importance to support the high priority safety applications in vehicular ad hoc networks (VANETs). Hassan omar proposed VeMAC, a novel multichannel TDMA MAC protocol proposed specifically for a VANET scenario. The VeMAC supports efficient one-hop and multi-hop broadcast services on the control channel by using implicit acknowledgments and eliminating the hidden terminal problem. The protocol reduces transmission collisions due to node mobility on the control channel by assigning disjoint sets of time slots to vehicles moving in opposite directions and to road side units. But the protocol has high packet loss & does not support different class of broadcast services. Taking this as motivation we propose a fuzzy scheduler based mechanism to ensure QOS for different class of broadcast messages along with VeMAC. Through simulation we measure the packet delivery ratio & prove that our mechanism is able to increment the delivery ratio by 20% over VeMAC.Key words: fuzzy scheduler, medium access control, reliable broadcast, TDMA, vehicular ad hoc networks.

Advanced Digital Image Compression Technique Using Curvelet TransformAbstract: In real time applications Image Compression plays a major role in storage memory and transmission bandwidth. As many compression methods are existing, selection of compression methods depends upon the quality in image reconstruction. Two popular compression methods are Wavelet and Ridgelet methods. Wavelet method has affected by the blocking artifacts and Ridgelet is designed to handle only line and edge singularities. This paper proposes a compression method using curvelet transform. The Curvelet Transform overcomes the drawbacks of above two methods and also has improvement in PSNR because of adaptive threshold.Key words: PSNR, Retained Coefficients, Ridgelet Transform Reference [1] Sayood, Khalid (2000)," Introduction to Data Compression", Second edition Morgan Kaufmann.

Load-deflection analysis of flat & corrugated stainless steel diaphragms by theoretical & finite element methodAbstract: In this study analytical model for pressure deflection relationship of flat & corrugated stainless steel (SS-304, ASTM A-240) diaphragms has been proposed. The load-deflection analyses of flat and corrugated stainless steel diaphragms are performed to compare the sensitivity of the flat and corrugated diaphragm. The application of corrugated diaphragms offers the possibility to control the sensitivity of thin diaphragms by geometrical parameters. Depth of corrugations, thickness of diaphragms, and number of corrugations plays an important role to increase the mechanical sensitivity of the corrugated diaphragm.

The access to information being one of the most important. Worms cause major security threats to the Internet. Worms are software components that are capable of infecting a computer and then using that computer to infect another computer. The cycle is repeated, and the population of worm-infected computers grows rapidly. Smart worms cause most important security threats to the Internet. The ability of smart worms spread in an automated fashion and can flood the internet in a very short time.

Simulation Study of Indirect Current Control Technique for Shunt Active FilterAbstract: Solid state control of ac power using thyristors and other semiconductor devices are used extensively in number of applications such as adjustable speed drives (ASD's), furnaces, computers power supplies and asynchronous ac–dc–ac links. These power converters behave as nonlinear loads to ac supply system and cause harmonic injection, lower power-factor, poor voltage regulation, and utilization of ac network. There is a great need to mitigate these harmonic and reactive current components. Active Power Filters are a viable solution to these problems. In this project work a three-phase shunt active filter is used to eliminate supply current harmonics, correct supply power-factor, and balance the nonlinear/linear loads.Key words: Shunt active filters, indirect current control, harmonics, voltage stability, current control Reference [1] Peng.F.Z, Akagi.H, Nabae.A, "A new approach to harmonic compensation in power systems- a combined system of shunt passive and series active filters," IEEE Trans.

VLSI Implementation of Fractional-N Phase Locked Loop Frequency SynthesizerAbstract: Power is the amount to function or generating or shelling out energy. This means that, it is a way of measuring how fast a function can be carried out. It means it is an important parameter. So to have less power consumption, this work is implemented using VLSI technology. This paper presents the design and simulation of VLSI based low power fractional- N Phase locked loop frequency synthesizer. This phase locked loop is designed using VLSI technology, which in turn offers high speed performance at low power. For improving the performance of fractional-N phase locked loop, Loop filter and sigma-delta modulator are the most important components. The loop filter bandwidth limits the speed of switching time between the synthesized frequencies. The periodic operation of dual modulus divider introduces phase noise in the PLL. To eliminate this phase noise, the digital sigma-delta modulator is used which generates a random integer number with an average equal to desired fractional ratio and pushes the spurious contents to higher frequencies. Noise shaping concentrates the quantization noise produced at the PFD output into the higher frequencies where it is removed by the low-pass filter.Key words: Sigma-Delta modulator; Phase Noise, Phase Locked Loop; Fractional-N Frequency Synthesizer Reference [1] N.

Process of Energy Audit of Commercial building & SubstationAbstract: The paper highlights the necessity of undertaking performance analysis and energy audit study of an electrical installation, more particularly a power substation on regular basis. A 630 MVA, 400/220 kV substation was identified and a detailed study was carried out to assess the various station performance parameters under different operating conditions. It was observed that the installed capacity of the station (transformer) was very large compared to the actual load it had to supply. Thus the station was under loaded and underutilized for the major period of its operation. This reduced the operational efficiency of the station. Secondly the incoming line voltage level was remaining high during most of the period of operation.Index Terms: Bus reactor, Energy audit, Extra High Voltage (EHV) substation, Performance analysis, Station efficiency, Transformer efficiency, Power quality, Technical and commercial viability.

The circuit is designed in GPDK 90nm CMOS technology, with a supply voltage of 1.2V. The design is based on a differential current steering topology. The differential output of the DAC is loaded with two resistors and a full-scale differential voltage of 0.9Vpp is generated. Different current cell architectures are compared and Cascoding is selected for unit current cell design. One big advantage with this architecture is that almost all current goes through the output, and that makes this architecture power efficient. This type of converter is also superior when it comes to high-speed D/A converters.

In response to increasing electrical energy costs, thermal storage technology has recently been developed. This paper presents an introduction to previous works on thermal energy storage using PCM and their applications. The choice of the substances used largely depends upon the temperature level of the application. Phase change material (PCM) are one of the latent heat materials having low temperature range and high energy density of melting– solidification compared to the sensible heat storage. Latent heat thermal energy storage (LHTES) with phase change materials (PCMs) deserves attention as it provides high energy density and small temperature change interval upon melting/solidifying. Phase change materials (PCMs) are becoming more and more attractive for space heating and cooling in buildings, solar applications, off-peak energy storage, and heat exchanger improvements. Latent heat thermal energy storage (LHTES) offers a huge opportunity to reduce fuel dependency and environmental impact created by fossil fuel consumption.Key words: Phase Change Material (PCM), renewable energy, Thermal Energy storage, Latent heat thermal energy storage (LHTES), high energy density. Reference (1) To provide an overview of phase change materials use in the context of power demand reduction. (2) To open new possibilities for eventual collaboration with the IEEE members. (3) To be able to promote synergetic solutions and processes in the domain of energy management. (4) In the present paper, a detailed study on PCM incorporation in building material, PCMs integration with building architecture for space heating, space cooling and in combination of heating and cooling has been carried out. (5) The optimization of these parameters is fundamental to demonstrate the possibilities of success of the PCMS in building materials. Therefore, the information like operational range and limitations evolved in a project with PCM's as heat transport medium and elaborate calculation for analysis supported by a simulation programme would definitely be a remarkable and reckonable guidance for deciding and designing PCMs in building application.

IMPROVING DESIGN AND OPERATION OF STEAM BASED TURMERIC COOKING PROCESSAbstract: In large scale turmeric boiling the conventional plants is used with multiple cooker and boiler assembly placed on trolley. The plant is provided with furnace, condensate extraction mechanism, packed pressure vessels and mobile plant. Here in boiling, the turmeric rhizomes are placed in the cooker and the steam is supplied from the boiler to the pressure cooker and the turmeric is boiled. In traditional plants the boiling is done without maintaining the pressure in the vessel, so the boiling is inefficient. Along with that the leakage problems related with pressure vessel gives rise to heat loss. Overall the losses are much more and the process is not optimized. The efficiency of the actual processing plant is 13.19% which is very less. This is due to the lot of losses from every part of plant. The losses are very hard to control in minimum cost. So the objectives of this project are Reduce cooking time, Recycle condensate, Reduce labor effort and cost, Reduce fuel consumption and Reduce heat losses.Key words: cur cumin percentage, pressure vessel design and analysis, low cost insulation, condensate recycling, heat recycling.

Exhaust Emissions and Its Control Technology for an Internal Combustion EngineAbstract: The automobiles play an important role in the transport system. With an increase in population and living standard, the transport vehicles as well as car population is increasing day by day. In addition to this there is steep increase in the number of two wheelers during the last two decades. All these are increasing exhaust pollution and particularly in metros as density of these vehicles in metros are very high. The main pollutants contributed by I.C. engines are CO, NOX unburned hydro-carbons (HC) and other particulate emissions. Other sources such as Electric power stations industrial and domestic fuel consumers also add pollution like NOX, SO2 and particulate matters. In addition to this, all fuel burning systems emit CO2 in large quantities and this is more concerned with the Green House Effect which is going to decide the health of earth.Key words: Exhaust pollution, Hydro-carbons, NOx emission, Petrol engines, diesel engines, CO Emissions, SO2 Emissions, CO2 Emissions, Particulate matters, Green house effect .

Comparing the Effect of Different Metal Plates and Lead Apron for Reducing the Dose Rate from Cs-137 and Ba-133 Gamma RayAbstract: The lead aprons are used as the standard radiation attenuating shields for nuclear medicine workers. Unfortunately, a lead apron is relatively heavy and leads to musculoskeletal complaints for users at overtime. In this study, the Monte Carlo code MCNP4C was applied to assesses the effect of 0.5 mm lead and different kinds of metal plates and appointed equivalent dose rate. Two radiation sources namely Cs-137 and Ba-133 were used that emit gamma rays of 140 keV and 511keV energy respectively. In this work, eight different plates made of Pb, Pb–Sb and combination of six other metals employed as radiation shield in form of 0.5 mm thickness sheets with dimension of 50 cm ×50 cm. The distance of radioactive sources from the detector was 30 cm. This study showed that light weight aprons containing 0.5 mm Bi, or combination of metals such as Bi-Pb or Bi-Sb-W alloys decrease weight of apron 10, 26 and 5 percent respectively, and all of them have same attenuation compared with pure lead. Results compared using "t test" statistical analysis. This research shows that Bi, Bi-W-Sb and Bi-Pb alloys, as radiation shields, are more suitable than lead. This is due to having same radiation attenuation as lead, but lighter weight.Key words: Nuclear medicine- lead apron - equivalent dose rate. Reference [1] Takano Y., Okazaki K., Ono K. and Kai M.

A Comparative Study of Predictive Models for Densification Parameters of Briquettes Produced From Two Species of CorncobAbstract: Corncob is a renewable energy resource, which its great potential for renewable energy generation has not been fully utilized. Corncobs from white and yellow maize were selected, sun-dried and their moisture contents were determined using ASAE standard. The residues were subjected to size reduction process and three particle sizes 4.70, 2.40 and 0.60 mm were selected. Starch mutillage (binder) was added to the residues at three levels of percentage binder ratios 20, 25, and 30 % by weight of the residue. A briquetting machine was used to form briquettes at three levels of pressures of 2.40, 4.40 and 6.60 MPa with observation of a dwell time of 120 seconds. The bulk density of the unprocessed materials and relaxed briquettes were determined using ASAE standard. The initial, maximum and the relaxed densities of the briquettes were determined using the mould dimension, the relaxed briquette's dimension and ASAE standard method of determining densities. Also determined were the compaction, density and relaxation ratios of the formed briquettes. Percentage axial and lateral expansions were also determined. The experimental data were subjected to regression analysis. A statistical package SPSS version 11.0 was used.Key words: Briquettes, Corncob, Densification, Predictive model, Regression analysis, Reference [1] FOS, (2006) Federal Office of Statistics, Agricultural Survey, 2003/04, Federal Ministry of Agriculture (June, 2006).

On The Onset of Rayleigh-Bénard Convection in a Layer of FerrofluidAbstract: The onset of Rayleigh-Bénard convection in a horizontal layer of ferrofluid is investigated by using Galerkin weighted residuals method. Linear stability theory based upon normal mode analysis is employed to find expressions for Rayleigh number and critical Rayleigh number. The boundaries are considered to be free-free, rigid-free and rigid-rigid. It is also observed that the system is more stable in the case of rigid-rigid boundaries and least stable in case of free-free boundaries.

Parallelization of Cryptographic Algorithm & Key Identification Using Genetic Algorithm ApproachAbstract: Now days, the amount of transfer of data over large network is increasing day by day. As there is increase in data transfer, simultaneously there are security threats that are arising with it. In this paper we are proposing cryptographic systems that make use of genetic algorithm to securely transfer the data over large network. This approach helps us to provide high achievability to transfer data securely. The techniques that we are using for encryption & decryption are based on genetic algorithm which will help us to efficiently encrypt the data which is resistible for any kind of external attacks. Then we will parallelize it using Open Mp language which accelerates the transformation of data to achieve high security. Then analyze the performance for both code serial and parallel execution.Key words: The genetic algorithm, Linear generation Equation, Genetic operator, Open MP Reference [1] Benjamin Arazi, "Vehicular Implementations of Public Key Cryptographic Techniques", IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY, VOL. 40, NO. 3,pp 646-653, AUGUST 1991.

E-Shaped Wideband Conformal AntennaAbstract: A compact wideband antenna with cylindrical conformal geometry is proposed . The radiating element of this antenna consists of an E-shaped patch that assumes a conformal orientation relative to the cylindrical surface in order to yield maximum bandwidth. The antenna is fed by waveguide feeding connected to the radiating patch at the longer side Radiation properties of the proposed including far-field patterns, axialratio, directivity, input impedance and voltage standing waveratio (VSWR), are studied simulating through HFSS (High Frequency Simulation Software).Simulation results are in good agreement, nearly equal E- and H-plane far-field patterns withhigh degree of axial symmetry over a bandwidth of more than 50%. Also, over a bandwidth of about 24% the axial ratio remains below 3 dB.

| 173. | Seismic Response Of Reinforced Concrete Braced Frames
Seismic Response Of Reinforced Concrete Braced FramesAbstract: Braced frames widen their resistance to lateral forces by the bracing action of inclined members. The braces stimulate forces in the associated beams and columns so that all work as one like a truss with all members subjected to stresses that are for the most part axial. This axial reaction results in less moments and in turn smaller sizes of beam and column sections compared to moment resisting frames. A concentrically braced frame has minor eccentricities in the joints of the frame that are accounted for in the design (which is tried with V-braced or K-braced or concentrically braced frames for this work). This paper presents the elastic seismic response of reinforced concrete frames with reinforced concrete bracing member in K or inverted – A or V – braced pattern which are analyzed numerically for twelve storey building with 5-bay structures. This approach focuses on the arrangements of V-braces in a particular bay, level and combinations thereof to reduce the lateral displacement ultimately to achieve an economy in comparison with similar moment resisting frames. Results are concluded from graphs and discussed comprehensivelyKey words: Bare Frames, Baywise & Levelwise Braced Frames, V-Braced Frames, Concentrically Braced Frames (CBF), Outriggers.

Various aspects of this measure of uncertainty are considered, including its connection with the residual entropy. Results on the past entropy is obtained by using the reversed hazard function of X, which is receiving increasing attention in reliability theory and survival analysis. The formula for the past entropy H(t) when X is exponentially distributed is obtained and this formula is utilized for our application part. The formulaH(t) for peripheral administration of CRH is obtained and found that the stress variables increased monotonically upward with respect to time.Key words: Residual Lifetime, Reversed Hazard Function, hCRH, oCRH.

The fuzzy logic controllers have been used to control many nonlinear systems. They are designed in various forms in the Matlab- Simulink environment with Mamdani type fuzzy inference system. The Inverted Pendulum system (also called "cart-pole system") is a challenging,nonlinear and unstable control system. By controlling the force applied to the cart in the horizontal direction, the inverted pendulum can be kept in various unstable equilibrium positions.

Experimental Study on Conversion of 4 Stroke Gasoline Internal Combustion Engine into Enriched Compressed Natural Gas Engine To Achieve Lower EmissionsAbstract: In spark ignition engine with gasoline and compressed natural gas as fuel, performance and emissions results were recorded under steady state operating conditions. The engine is run at wide open throttle and constant speed ranging from 1000 rpm to 5000 rpm with 500 rpm increment. On average, we have observed that CNG operation results in 3-12% less Mechanical efficiency compared to gasoline. In terms of exhaust emissions, the results show that HC, CO and CO2 have got reduced significantly by 40-66%, 54-98% and 28-30% respectively compared to gasoline. Now a days the emission norms are very stringent. Emission standards like Bharat Stage IV (Equal to EURO IV) is implemented in India, in 13 major cities, since April 2010 and Bharat Stage III is implemented nationwide since April 2010. To meet the EURO V norms this can be further modified into Hydrogen Enriched Compressed Natural Gas (HCNG) system by using hydrogen with CNG. This process is carried out to reduce the exhaust emissions at its best and to have the complete combustion of fuel from the beginning itself.Key words: Bharat Stage, CNG, Emission standards, EURO, Exhaust gas analyzer Reference [1] Brett Jarman, "Beyond CNG – Natural gas vehicles in the Years Ahead", The Automotive Research Association of India, 2009 [2] Semin, Abdul Rahim Ismail, and Rosli Abu Bakar, " Gas Fuel Spray Simulation of Port Injection Compressd Natural Gas Engine Using Injector Nozzle Multi Holes", European Journal of Scientific Research, pp.188-193, 2009.

The designed SEPIC employs the peak-current-mode control with the current command generated from the input PV voltage regulating loop, where the voltage command is determined by both the PV module maximum power point tracking (MPPT) control loop and the battery charging loop. The control objective is to balance the power flow from the PV module to the battery and the load such that the PV power is utilized effectively and the battery is charged with three charging stages. This paper gives a detailed modeling of the SEPIC with the PV module input and peak-current-mode control first. Accordingly, the PV voltage controller, as well as the adaptive MPPT controller, is designed. An 80-W prototype system is built. The effectiveness of the proposed methods is proved with some simulation and experimental results.Key words: Maximum power point tracking (MPPT), power balance control, single-ended primary inductance converter (SEPIC), stand-alone Reference [1] M.

Experimental Studies and Controller Design of Shell and Tube Heat Exchanger Using With and Without InsertAbstract: An experimental study of heat transfer characteristics with and without insert was found using water –water system on 1-2 pass shell and tube heat exchanger. Experimental results such as exchanger effectiveness, overall heat transfer coefficient were calculated using with and without insert. There is improvement in overall heat coefficient, efficiency in using twisted tape. In all the process industries the process variables like flow, pressure, level and temperature are the main parameters that need to be controlled in both set point and load changes.

A Novel Routing Algorithm Based On Link Failure Localization for MANETAbstract: The routing in Mobile Ad hoc Network (MANET) is a critical task due to dynamic topology. Many routing protocols were proposed which are categorized as proactive and reactive routing protocols. Route maintenance is a great challenge in MANET due to frequent link failure which causes high data loss and delay. To counter such problems, lots of link repair mechanisms were proposed, but all these have their own limitations. This paper proposes a novel routing algorithm for route maintenance based on Link Failure Localization called DSR-LFL. DSR-LFL takes decision on the basis of location of failure link in source route. Simulation results shows DSR-LFL improve the Packet Delivery Ratio, Throughput and decrease the Routing Overhead, End-to-End Delay as compared to Dynamic Source Routing (DSR) protocol.Key words: DSR, MANET, DSR-LFL, routing, salvage Reference [1] D.B.

Investigating the Effects of Coarse Aggregate Types on The Compressive Strength Of ConcreteAbstract: Concrete has a far greater strength than mortar and sandcrete of the same cement: aggregate ratio. This exceeding strength is, most times, found to be triple (or more) that of mortar. Coarse aggregates, which are the interest of this study, make the difference. Three different types of coarse aggregates, with 20mm maximum size, were employed in the investigation, namely; crushed granite, washed gravel, and unwashed gravel. The grading and relative densities of the aggregates were studied. The mix ratio and water/cement ratio adopted for the study was 1:3:6 and 0.6 respectively. The target mean strength at 28 days was 15N/mm2. Twelve concrete cubes (150mm x 150mm x 150mm) were cast for each coarse aggregate type of which four were crushed at each maturity age namely; 7, 14, 21, and 28 days. All cubes reached the target mean strength after 7 days of curing. The 28 day strengths of the concretes made with crushed granite, washed gravel, and unwashed gravel were 25.1 N/mm2, 20.0 N/mm2, and 16.9 N/mm2 respectively. Consequently, it was concluded that the strength of concrete depends greatly on the internal structure, surface nature and shape of aggregates.Key words: aggregates, concrete, compressive strength, granite, gravel, curing.

Text Steganography Based On Unicode of Characters in MultilingualAbstract: Network security, and secure communications through public and private channels are more important issue specially when computer usage is increasing, for both social and business areas. Data hiding is one of approach to obtain a secure communication medium and protecting the information during transmission. Text steganography is most challenging because of the presence of very less redundant information in text documents as compared to the images and audio. In this paper a novel method is proposed for data hiding in English scripts using Unicode of English alphabet in another languages. In this method, 13 characters from English alphabet was chosen for hiding process which have appearance in another languages. Two bits embedded in one time, using ASCII code for embedding 00, and using Unicode of multilingual for embedding 01, 10, and 11. This method has a height hiding capacity based on specific characters in each document. As well as have very good perceptual transparency and no changes in original text.Key words: Multilingual characters, Text hiding, Unicode standard. Reference [1] M.

CBIR is used for automatic indexing and retrieval of images depending upon contents of images known as features. This paper provides the survey of technical achievements in the research area of image retrieval. In this paper, a survey is done on the different methods of content based image retrieval for the classification of texture and color. For the classification of the extracted features we have used SVM. Classification using cascaded SVM is also used here for solving large-scale pattern classification problems. Cascaded SVM has advantages over conventional SVM.Key words: CBIR, Feature Extraction, Texture and Pattern Classification.

Studies on Double Stage Engine Mount for Vibration ReductionAbstract: It is necessary to design a warship so as to evade detection by enemy ships or submarines. A recent technique used involves mounting all vital machinery on a double stage vibration isolation system. In cases where there is a demand for high structure-borne noise attenuation a two-stage mounting system (also called as raft mounting) is employed. The aim is to reduce vibration levels from machinery to foundation, and thereby to reduce radiation noise levels from ship hull. The vertical vibrations of the system are assumed to be most predominant. The other types of vibrations like rocking or transverse type of vibrations will be assumed to be negligible and to be taken by the mounts. We will analyze effects of changes in various system parameters like spring stiffness and damping coefficient on the dynamic response of the system. The analysis which is aimed at finding the parameters of mounts and then optimizing the mounts, is based on discrete system modeling.Key words: warship machinery foundation, double stage vibration isolation, two degree freedom systems, marine engine foundation.

Performance Testing Of a Truncated Pyramid Solar Thermal CookerAbstract: This paper presents the results of performance testing of a truncated pyramid solar thermal cooker developed in the Department of Mechanical Engineering, Kaduna Polytechnic, Kaduna, Nigeria. The truncated pyramidal geometry concentrates the incident solar energy radiations towards the absorber placed at the bottom, and the glass glazing material at the top facilitates the trapping of energy inside the cooker. During testing, the highest plate stagnation temperature achieved, under no-load condition and reflector covered with black cloth, was 145 oC. In full-load condition the temperature of 5.2 kg of water inside the cooker rose from 60 oC to 90 oC in 72 minutes. The First Figure of Merit, F1, was calculated to be 0.120 and the Second Figure of Merit, F2, was found to be 0.410, thus meeting the standard prescribed by the Bureau of Indian Standards for box-type solar cookers. The relatively high absorber plate temperature developed during testing demonstrates that the cooker can be used for all the four major methods of cooking, viz: boiling/ steaming, baking, roasting/grilling, and frying (of eggs).Key words: Cooker, performance, pyramid, solar, testing, thermal, truncated Reference [1].

The cooker was designed to cook food equivalent of 12 kg of dry rice per day, for a relatively medium size family. For effective performance, the design required that the solar cooker track the sun frequently, and a linear actuator (superjack) was adopted for this purpose. Preliminary test results show that the overall performance of the solar thermal cooker is satisfactory. The cooker is capable of cooking 3.0 kg of rice within 90 – 100 minutes, and this strongly agrees with the predicted time of 91minutes.Key words: Cooker, design, development, dish, thermal parabolic, solar Reference [1].

Effect of Design Parameter on the Performance of Lithium Ion BatteryAbstract: The demand of alternative energy sources increasing because gasoline reserve in world is depleting day by day. Various alternative energy resources is being used to meet out the requirement of the human beings. Battery are also a kind of alternative energy source. Due to limitation of fuel reserves researchers have focused towards the lithium ion batteries to power automotive vehicles. Such as electric vehicle (EV), hybrid electric vehicle and plug-in hybrid electric vehicles. Apart from that lithium ion battery are being used in various small electronic portable devices. In this work we have simulated mathematical model for lithium ion battery to see the effect of kee parameter such as porosity of positive electrode, porosity of negative electrode and radius of solid particle in negative electrode and radius of solid particle in positive electrode. I have seen that increasing the particle radius and porosity in negative electrode greatly affect the charge and discharge behaviour of the battery apart from that effect of increasing particle radius and porosity of positive electrode has minute effect over the battery behaviour.Reference [1] I.

Fast Dynamic Control Behavior of a Capacitor Supported Dynamic Voltage Restorer (DVR)Abstract: Dynamic voltage restorers (DVRs) are the most popular Devices in industry to reduce the undesirable effect of voltage sags/swells to sensitive loads. The DVR is a series connected device whose function is to maintain sensitive loads voltage within the permissible range. This work provides us to find the optimal location and the optimal DVR settings to enhance the distribution related loading issues. It is based on the boundary control method with the second-order switching surface. The load voltage can ideally be reverted to the steady state in two switching actions during a supply voltage dip. The outer loop is used to generate the DVR output reference for the inner loop. It has three control modes for achieving two different functions, including the output regulation and output restoration. The first mode is for regulating the capacitor voltage on the dc side of the inverter, so that the output of the DVR is regulated at the nominal voltage. Conventional voltage-restoration technique is based on injecting voltage being in-phase with the supply voltage.Key words: Voltage sag, voltage swell, dynamic voltage restoration (DVR), power quality, fluctuation.

Building SoundWorks, the New Revolutionary Computer-Based AudiometerAbstract: The goal of this engineering project was to design a computer-based audiometer called SoundWorks to provide users with a simple and cheap way to monitor hearing loss. SoundWorks was created to test people for their hearing loss in an automatic manner. It generates test tones of specific frequencies at specific ascending sound levels for which the testee responds on hearing the tone through a calibrated headphone set/amplifier setup. It covers a normal (100Hz-8000Hz) and an extended range up to 20,000Hz and covers sound levels from 0dB to 120dB. An audiogram (plot of threshold values) is updated in real time. A report is generated automatically after both ears are tested for audiologist interpretation. Options include pulse or continuous test tone, silence or white noise in ear not being tested. Differentiating enhancements of SoundWorks include hysteresis of threshold, multilingual voice and text prompts, manual mode for spot checks, speech mode, and tinnitus matching mode. This product was developed in C# language on Microsoft Windows 7, debugged, and fully validated for complete functionality. Calibration of all sound levels, frequencies, and channels has been completed. This product aims to provide a portable/affordable hearing test capability for under-served economies, volunteer organizations, and frontline military medical units for quick screening of personnel exposed to excessive sound levels. Future plans include medical certification and porting to mobile devices such as smartphones and tablets.Reference [1] ASHA. (2012). Sensorineural Hearing Loss.

Simulation of Direct Voltage Control for a Stand-Alone Wind-Driven Self-Excited Induction Generator with Improved Power QualityAbstract: Control of terminal voltage and frequency of a stand-alone wind-driven self-excited induction generator with variable loads is proposed using an improved direct voltage control (DVC) strategy. The DVC strategy, including a proportional-integral (PI) regulator, lead–lag corrector, and a feed-forward compensator, is designed based on the system transfer function matrix. The PI regulator can eliminate the steady-state tracking errors of the terminal voltage. The lead–lag corrector is employed to enlarge the phase stability margin of the dominant loops while the feedforward compensator is adopted to mitigate the voltage harmonics resulting from the cross-coupling dynamics. The simulation and experimental results verify that the proposed strategy has a fast dynamic response and can effectively control the generated voltage with low harmonic distortions under different linear or nonlinear loads.Index Terms: Direct voltage control (DVC), harmonic compensation, induction generator, stand-alone wind energy conversion systems.

Analysis of pre-stressed floor grid system.Abstract: the sequential pre-stressing of grid structure is very important parameter in the waffle slab. Such slabs have several advantages over the more conventional slabs when used as decks for concrete bridges and as process floors in semiconductor manufacturing plants.Generally waffle slab is a monolithically construction of slab and beams, it may be one directional rib or in the both direction. In the grid structure (i.e Beam) is the key sectional properties which takes maximum contribution of load carrying in the waffle slab. This paper presents analysis in to two formats. First format is sequential and immediate pre-stressing of grid (waffle) slab for two selected patterns. Second format is to take a single cross beam from same grid (waffle) slab and analyze the same beam for differential pre-stressed forces. Here cross beam is analyzed by using direct stiffness method which is based on finite element method. Results was shows that while pre-stressing of main beam with stretching of one cable will reduce the bending moment and further alternate stretching will case cracks propagations in the secondary beam .br />Key words: Cross beam analysis, waffle slab, grid structure, sequential pre-stressed.

Modelling Low Field Electron Mobility In Group III Nitride MaterialsAbstract: Temperature and doping dependencies of electron mobility in both wurtzite and zincblende GaN structures have been calculated using an iteravive technique. The following scattering mechanisims, i.e, impurity, polar optical phonon, acoustic phonon, piezoelectric and electron plasmon are inculded in the calculation. Ionized imurity scattering has been treated beyound the Born approximation using the phase-shift analysis. It is found that the electron mobility decreases monotonically as the temperature increases from 100K to 600K. The low temperature value of electron mobilty increases significantly with increasing doping concentration. The iterative results are in fair agreement with other recent calculations obtained using the relaxation-time approximation and experimental methods.Key words: GaN; SiC; Wurtzite; Zincblende; Plasmon Reference [1] S Nakamura, M Senoh and T Mukai, Appl.

FEM Analysis And Experimental Investigation For Lateral Extrusion Of Hexagonal HeadAbstract: The growing interest in the dynamic simulation modeling of metal forming processes in recent years has brought about the development of different techniques. The finite element technique is eminently suitable for analyzing lateral extrusion of hexagonal sections. Variations in load and flow direction of metal are greatly affected by the extruded geometry in this process. Keeping in view the above factors as an objective, an experimental die-punch set-up for lateral extrusion is designed and the process is simulated using finite element method both for estimation of load requirement and metal flow patterns. The series of experiments have been carried out to find the extrusion load and the direction of metal flow at different die geometry, taking commercial lead as the billet material. The predictions both in extrusion load and the deformed configuration are in good agreement with the experiment qualitatively under different geometry conditions. Progressive flow of metal at different die geometry has been investigated.Key words: Flow stress, Friction factor, Forming load, Metal flow, Strain-effective Reference [1] O.

Performance of Exhaust Gas Recirculation (EGR) System on Diesel EngineAbstract: Exhaust Gas Recirculation (EGR) System means to use the Exhaust Gas coming from Exhaust Manifold to Inlet Manifold in order to reduce the Emission of NOX, which is particularly very harmful. Engine without EGR are more pollutant & uses more atmospherically air for combustion. By Implementation of EGR system in Engine, the Partial Exhaust Gas is re-circulated again in Engine. It is first cooled in EGR Cooler & then it is mixed with atmospheric air & then passed to Combustion Chamber. Fresh atmospheric air required is reduced & automatically pollutant (CO, CO2, HC, NOX etc.) is reduced. The aim of this work is to review the potential of exhaust gas recirculation (EGR) to reduce the exhaust emissions, particularly NOX emissions, and to delimit the application range of this technique. The purpose of project is to plot the graph between Brake power (B.P.) Vs. NOX, B.P. Vs. CO2, B.P. Vs CO with & without implementation of EGR. The Major Task of the proposed work includes Calculation of NOX content in I.C. Engine with or without the Implementation of EGR System. The system is very much Eco Friendly. Using Exhaust Gas Recirculation (EGR) Technique in engines, the emissions are very much controlled.

Radiation pattern is an important characteristic of an antenna. Radiation pattern of a single antenna element is fixed. Required radiation patterns can be generated from array of antennas. Different pattern synthesis techniques are reported in the literature. Generated patterns from selected pattern synthesis techniques can further be optimized using optimization techniques like genetic algorithms. Genetic Algorithm(GA) is a popular optimization technique for better solutions.

Simulation of D-Statcom and Dvr in Power SystemsAbstract: Power quality problem results in a failure or a mis-operation of end user equipments. Utility distribution networks, sensitive industrial loads and critical commercial operations suffer from various types of outages and service interruptions which can cost significant financial losses. In developing countries like India, where the variation of power frequency and many such other determinants of power quality are themselves a serious question, it is very vital to take positive steps in this direction .The present work is to identify the prominent concerns in this area and hence the measures that can enhance the quality of the power are recommended. In this paper the techniques of correcting the supply voltage sag, swell and interruption in a distributed system is discussed. A DVR injects a voltage in series with the system voltage and a D-STATCOM injects a current into the system to correct the voltage sag, swell and interruption. Comprehensive results are presented to assess the performance of each device as a potential custom power solution.Key words: D-Statcom, DVR, voltage dips, swells, interruption, power quality, VSC.

Performance Evaluation of MANET with Black Hole Attack Using Routing ProtocolsAbstract: Mobile Ad hoc networks (MANET) are collection of wireless nodes that communicate with each other with the help of wireless links. MANET is vulnerable to different attacks due to its feature open medium, dynamic topology, no central authority and no clear defense mechanism. One of the attacks is black hole attack in which a malicious node intercepts the packets being transmitted to another node in the network. As the data packets do not reach the destination, Data loss occurs which affects the performance of network badly. Our aim of the paper is to analyze the impact of the Black hole attack on MANET performance and how it affects the various performance metrics of the network by comparing the network performance with and without black hole nodes.Key words: Black hole attack, Manet, Routing protocols.

Content Based Image Retrieval System for Kannada Query Image from Multilingual Document Image CollectionAbstract: In a multilingual country like India, a document may contain text words in more than one language. It is reasonably natural that the documents produced at the border regions of Karnataka may also be printed in the regional languages of the neighbouring states like Telugu, Tamil, Malayalam and Urdu. An electronic Searching system for Kannada text, based on the content is needed to access such multilingual documents. So, it is necessary to identify different language portions of the document before the retrieval. The objective of this paper is to propose visual clues based procedure to identify Kannada text from a multilingual document which contains Hindi, English and Malayalam text portions along with Kannada.Key words: Content based image retrieval, Correlation Coefficients, Feature Extraction, Multi-lingual Document image, Script Identification.

Comparison of Channel Estimation Techniques for OFDMAbstract: Orthogonal frequency division multiplexing (OFDM) is a unique case of multi-carrier transmission and it can maintain high data rate requirement of wireless systems. Since channel estimation is an essential part of OFDM systems, it is difficult to understand the basis of channel estimation techniques for OFDM systems, so that the most suitable method can be applied. The estimation of channel at pilot frequencies is based on LS and MMSE estimation techniques by using 16QAM modulation scheme. The purpose of this paper is to use MAT LAB simulation of OFDM to see how the Bit Error Ratio (BER) of a transmission varies when Signal to Noise Ratio (S/N Ratio) and Multi propagation effects are changed on transmission channel. Also to compare the Least Square & mean squared error performance for various channel models such as AWGN, Rayleigh & Rician using 16QAM modulation scheme.Key words: BER, ISI, OFDM, S/N,QAM Reference [1] Sinem Coleri,Mustafa Ergen," Channel Estimation Techniques Based on Pilot Arrangement in OFDM Systems," IEEE Transactions on Broadcasting, "vol. 48, no. 3, September 2002 .

A Graphical Program That Eliminates the Out Dated 3.5" Disk Technology Used By the Stanford Research Multi-Channel Scaler/AveragerAbstract: A graphical program was created, to simplify the acquisition of data and data conversion from bin to ASCII, for data obtained by a Stanford Research Multichannel Scaler/Averager (SR430). The SR430 receives the data in the form of pulses from a photomultiplier tube (PMT). The PMT serves as the detector in a pulsed laser spectroscopy experiment. The program was created in LabVIEWTM which was developed by National Instruments. LabVIEWTM allows the user to code programming ideas by selecting and patterning graphical icons. The program presented in this paper eliminates the outdated and clumsy steps of saving the data in DOS format, on a 720K disk, using the 3.5" drive of the SR430, and then converting the data from bin to ASCII, using a DOS program. With this graphical program the user can save the data obtained by the SR430 in a spreadsheet ready format on a computer.Key words: LabVIEWTM, ASCII, PMT, SR430, Laser Spectroscopy Reference [1] Standford Research Sytsems, Model SR430 Multichannel Scaler/Averager Manaul, California, 1999.

Designing Multi-Agent Based Remote Process Monitoring SystemsAbstract: This paper presents an agent-based generic architecture for remote process monitoring. It is based on the fact that every process control system to be monitored can be represented in the form of an Algorithmic State machine (ASM) chart which is further translated into a corresponding State Transition Table (STT). By a little modification of the STT the entire process control system is represented as a succession of states each of which an agent can process. Thus by storing a copy of that table at the remote site and obtaining at each stage of the monitored process a feedback, this feedback information would serve as an index into the remotely stored table to crosscheck the validity of the feedback information with respect to each stage of the monitored process.Key words: Remote monitoring, process monitoring agents, state monitoring agents, real-time data capture, Graphical User Interface (GUI).

Spread Spectrum Code Design for MIMO Radar Estimation Using Compressive Sensing ModelingAbstract: We consider the problem of multiple- target estimation using a collocated multiple-input multiple-output (MIMO) radar system. We employ sparse modeling to estimate the un-known target parameters (delay, Doppler) using a MIMO radar system that transmits frequency-hopping waveforms. We formulate the measurement model using a block sparse representation. We adaptively design the transmit waveform parameters (frequencies, amplitudes) to improve the estimation performance. Firstly, we derive analytical expressions for the correlations between the different blocks of columns of the sensing matrix. Using these expressions, we compute the block coherence measure of the dictionary. We use this measure to optimally design the sensing matrix by selecting the hopping frequencies for all the transmitters. Secondly, we adaptively design the amplitudes of the transmitted waveforms during each hopping interval to improve the estimation performance. Further, we employ compressive sensing to conduct accurate estimation from far fewer samples than the Nyquist rate.Key words: Multiple input multiple output RADAR, Multiple targets, Compressive sensing and frequency-hopping codes.

Control of Heat Exchanger Using Hybrid Fuzzy-PiAbstract: In this paper the potentials of fuzzy logic based control techniques are explored by applying standard Mamdani based control methodology and a type of hybrid Fuzzy-PI controller for the control of hot water outlet temperature of a co-current shell and tube heat exchanger. Standard Fuzzy Logic Controllers (FLCs) need more information to compensate for nonlinearities when operating conditions change. Here a hybrid of conventional and fuzzy controller has been used to determine the controller actions for the dynamic plant subjected to change in operating conditions. The real time implementation of hybrid Fuzzy-PI controller is discussed and compared with a standard FLC.Reference 1. M.Chidambaram and Y.S.N.

Investigation Into Cable-Structure Interaction For Extradosed BridgeAbstract: Cable supported Bridge structures have distinctive dynamic behavior compared to any other type of bridge, especially the dynamic behavior. Support excitations sets structure to vibrate; cable excitations can be caused by rain, wind or stochastical vibration due to plying vehicles or due to vibration of deck. In modern cable-stayed / Extradosed bridges, the stay cables are often closely spaced, with the cable lengths and tensions gradually varying from position to position. The natural frequencies of their self-vibrations are therefore likely to be rather closely placed as well. Such boundary-induced vibrations of the stay cables are likely to complicate the overall dynamic behavior of the bridge. The paper focuses on dynamic behavior of Extradosed Bridges, dynamic behavior of Extradosed cables and possible interaction resulting into coupled mode of vibrations.Key words: Extradosed cable stayed bridge, Earthquake, Dynamic response, cable-structure interaction Reference [1] Katsuhiko Takami and Sumio Hamada (2005); Behavior of extradosed bridge with composite Girder; ASCE / Journal Of Bridge Engineering [2] H.

Simulation of Dynamic Voltage Restorer Using Matlab to Enhance Power Quality in Distribution SystemAbstract: Power quality is one of major concerns in the present era. It has become important, with the introduction of sophisticated devices, whose performance is very sensitive to the quality of power supply that results in a failure of end user equipment's. One of the major problems dealt here is the voltage sag. To solve this problem, custom power devices are used. One of those devices is the Dynamic Voltage Restorer (DVR), which is the most efficient and effective modern custom power device used in power distribution networks. Its appeal includes lower cost, smaller size, and its fast dynamic response to the disturbance. It can provide the most commercial solution to mitigation voltage sag by injecting voltage as well as power into the system. This paper presents modeling, analysis and simulation of a Dynamic Voltage Restorer (DVR) using MATLAB. The efficiency of the DVR depends on the performance of the efficiency control technique involved in switching the inverters. In this model a PI controller and Discrete PWM pulse generator is used.Reference [1] Hingorani N G, "Introducing Custom Power", IEEE Spectrum, 1995 pp. 4l–48.

ANN Based Surface Roughness Prediction In Turning Of AA 6351Abstract: Surface roughness is the predominant machining criteria in any machining process and plays a vital role in manufacturing industries. The present work focused on the modeling of surface roughness in turning of AA 6351 alloy with carbide tool. Cutting speed, feed and depth of cut were considered as machining parameters and surface roughness was considered as the response. Experiments were conducted to develop the linear regression equations based on Taguchi's experimental design methodology. Moreover, Artificial Neural Network (ANN) model was also developed for the surface roughness. Further, the performance of the developed model has been tested with the help of ten experimental test cases.Key words: AA 6351 alloy, turning, multiple regression model, Artificial Neural Network, surface roughness Reference [1] Grzesik W, A revised model for predicting surface roughness in turning, Wear 194(1-2), 1996, 143-148.

Slicing : A Efficient Method For Privacy Preservation In Data PublishingAbstract: In this paper we propose and prove a new technique called "Overlapping Slicing" for privacy preservation of high dimensional data. The process of publishing the data in the web, faces many challenges today. The data usually contains the personal information which are personally identifiable to anyone, thus poses the problem of Privacy. Privacy is an important issue in data publishing. Many organizations distribute non-aggregate personal data for research, and they must take steps to ensure that an adversary cannot predict sensitive information pertaining to individuals with high confidence. Recent work in data publishing information, especially for high dimensional data. Bucketization, on the other hand, does not prevent membership disclosure. We propose an overlapping slicing method for handling high into more than one column; we protect privacy by breaking the association of uncorrelated attributes and preserve data utility by preserving the association between highly correlated attributes. This technique releases mo correlations thereby, overlapping slicing preserves better data utility than generalization and is more effective than bucketization in workloads involving the sensitive attributeKey words: Overlapping slicing, privacy preservation, high dimensional data, privacy techniques Reference [1] C.

Applying Neuro-Fuzzy Architecture in Swmm Model for Best Management PracticesAbstract: Hydrologists are often confronted with problems of prediction and estimation of runoff, rainfall, contaminant concentrations, water stages, and so on. Moreover, engineers are often faced with real situations where little or no information is available. The processes and relationship between rainfall and surface runoff transport for a catchment area require good understanding, as a necessary pre-requisite for preparing satisfactory drainage and storm water management projects. In the hydrological cycle, the rainfall occurs and reaching the ground may collect to form surface runoff or it may infiltrate into the ground. The surface runoff and groundwater flow join together in surface streams and rivers which finally flow into the ocean. Urban drainage systems have changed from primitive ditches to complex networks of curbs, gutters, surface and underground conduits (links).Key words: Surface runoff, Drainage system, Hydrologic and Hydraulics elements Reference [1] Ahmed, S., Al-Mikhlafi, Das, B.K. and Kaur, P., (2003), "Water chemistry of Mansar Lake (India): an indication of source area weathering and seasonal variability", Envi.Geol, v. 44, p. 645-653.

The Optimization of Gamma Camera Using Changed the Area of Semiconductor Detectors by MCNP CodeAbstract: In this paper we tried to substitute an appropriate detector instead of NaI. The features of semiconductor detectors were studied to find a detector which works at the ordinary temperature, has less FWHM and more resolution. Therefore HgI2 and CZT detectors were selected and studied. The gamma camera with three difference detectors (NaI, HgI2 and CZT detectors) were simulated. We have shown that the resolution of HgI2 and CZT detectors are better than NaI. Studding of area variation of CZT, HgI2 and NaI detectors, the minimum FWHM and maximum resolution obtained at4.8 mm × 4.8 mm area. Finally the area of detectors hole were modified in order to gain the best possible pictures.Key words: Semiconductor; gamma camera; detector. Reference [1].

Design Of PID Controller In Automatic Voltage Regulator (AVR) System Using PSO TechniqueAbstract: In this paper, an evolutionary computing approach for determining the optimal values of the proportional-integral-derivative (PID) controller has been proposed. Proper tuning of such controllers is obviously a prime priority as any other alternative situation will require a high degree of industrial expertise. This paper demonstrated in detail how to employ the PSO method to search efficiently the optimal PID controller parameters of an AVR system. The proposed algorithm has been applied in the PID controller design for the AVR system. A MATLAB simulation has been performed and a comparative study between the proposed algorithms with the PID Controller Tuner has been studied in the presented work. In continuation of this, the proposed method was indeed more efficient and robust in improving the step response of an AVR system.Key words: AVR system, Particle Swarm Optimization (PSO), PID Controller, PID Controller Tuner.

Retrieval of Digital Images Based On Multi-Feature Similarity Using Genetic AlgorithmAbstract: Conventional relevance feedback schemes may not be suitable to all practical applications of content based image retrieval (CBIR), since most ordinary users like to complete their search in a single interaction, especially on web search. In this paper, we explore a new approach based on multi-feature similarity score fusion using genetic algorithm. Single feature describes image content only from one point of view, which has a certain one-sided. Fusing multifeature similarity score is expected to improve the system's retrieval performance. In this paper, the retrieval results from color feature and texture feature are analyzed, and the method of fusing multi-feature similarity score is described. For the purpose of assigning the fusion weights of multi-feature similarity scores reasonably, the genetic algorithm is applied. For comparison, other three methods are implemented. They are image retrieval based on color feature, texture feature and fusion of color-texture feature similarity score with equal weights. The experimental results demonstrate the image retrieval performance of the proposed method is superior to other methods.Key words: Image Retrieval, CBIR, Multi-Feature Reference [1] Barbeau Jerome, Vignes-Lebbe Regine, and Stamon Georges, "A Signature based on Delaunay Graph and Co-occurrence Matrix," Laboratoire Informatique et Systematique, University of Paris, Paris, France, July 2002,.

Power Aware BIST for Digital IC'sAbstract: Testing of digital VLSI circuits encounters many challenges as a result of rapidly growing semiconductor manufacturing technologies along with unexampled levels of design complexity and the gigahertz range of operating frequencies. These challenges include keeping the average and peak power dissipation and test application time within acceptable limits. This paper proposes a new output sequence of an LFSR to design a low-power test-pattern-generator for built-in self-test (BIST) to achieve reduction in the overall switching activity in the circuit-under-test (CUT). Conventional and low power test patterns are applied on an industry standard ISCAS-85 c432 27-channel interrupt controller circuit and total power consumption is measured. The obtained results show up to 18% power reduction for the proposed design. Fault simulation tool is used to estimate the number of test vectors required for high fault coverage of the interrupt controller. It generates 261 test vectors for the conventional TPG and 678 test vectors for the low power TPG, thus indicating 160% increase in test vectors. The results obtained show a significant increase in test application time for low power TPG.Key words: CUT, LP-TPG, Fault Coverage, Test Cycles, Test Vectors.

VANET is ad hoc network technology where cars or vehicles are used as mobile nodes to form a communication network. Routing protocols play a big vital role in terms of performance. MANETs and VANETs are infrastructure less networks, where they are similar in characteristics. The similarity in both cases is the nodes are in motion with their self organizing characteristics where there is no requirement of any fixed or existing infrastructure. [1]. The main purpose of VANET is to provide[2] ubiquitous connectivity while on the road to the mobile users, those are otherwise connected to the outside world. Due to the distinct features of VANETS, various problems can be tackled by the researchers. Applications developed for VANETS have very specific and clear goals such as providing intelligent and safe transport system.Key words: Routing protocols, simulation, VANET, Network Simulator, AODV, DSDV, OLSR Reference [1] Sweta Verma Sweta Verma* & Dr. Vivek Kumar**.

Image Resolution Enhancement by Using Multi Resolution Transform-DWTAbstract: In this paper we propose an image resolution enhancement technique based on the interpolation of high-frequency subbands obtained by discrete wavelet transform (DWT) and the input image. The proposed resolution enhancement technique uses DWT to decompose the input image into different subbands. Then, the high-frequency subband images and the input low-resolution image have been interpolated, followed by combining all these images to generate a new resolution-enhanced image by using inverse DWT. In order to achieve a sharper image, an intermediate state to estimate the high frequency sub bands by utilizing the difference image obtained by subtracting the input image and its interpolated LL sub band. The proposed technique has been tested on well-known benchmark images. The quantitative (peak signal to noise ratio) and visual results show the superiority of the proposed technique over the conventional and state-of art image resolution enhancement techniques.Key words: Discrete wavelet transform(DWT), image resolution enhancement, Interpolation, peak signal to noise ratio(PSNR).

Speed Control Of Three Phase Induction Motor By Fuzzy Sliding Mode And Genetic algorithmAbstract: This paper describes the use of robust control systems using fuzzy sliding mode and genetic algorithm (FSMC-GA) to control the speed of a three phase induction motor. First, sliding mode control that incorporates a fuzzy tuning technique (FSMC) is used to overcome the high control gains and chattering of the classical SMC. However, the fuzzy control rules are always built by designers with trial and error. We propose an optimization technique of FSMC using genetic algorithm. GA is used for determination of different controller parameters due to their fast convergence and their reasonable accuracy. The effectiveness of the complete proposed control scheme is verified by numerical simulation. The results of simulation showed that (FSMC- GA) presents better performances compared to the (FSMC).Key words: Induction motor, Vector control, Fuzzy control, Sliding mode control, Genetic algorithm Reference [1] A.Ghazel, De.

| 248. | Fuzzy Type-Ahead Search in XML Data
Fuzzy Type-Ahead Search in XML DataAbstract: In a traditional keyword-search system over XML data, a user composes a keyword query, submits it to the system, and retrieves relevant answers. In the case where the user has limited knowledge about the data, often the user feels "left in the dark" when issuing queries, and has to use a try-and-see approach for finding information. In this paper, we study fuzzy type-ahead search in XML data, a new information-access paradigm in which the system searches XML data on the fly as the user types in query keywords. It allows users to explore data as they type, even in the presence of minor errors of their keywords. Our proposed method has the following features: 1) Search as you type: It extends Auto complete by supporting queries with multiple keywords in XML data. 2) Fuzzy: It can find high-quality answers that have keywords matching query keywords approximately. 3) Efficient: Our effective index structures and searching algorithms can achieve a very high interactive speed.Index Terms: XML, keyword search, type-ahead search, fuzzy search.

Reducing Hot and Cold Utility Requirements for Finishing Column Section Using Pinch Analysis TechniquesAbstract: Pinch Analysis is a methodology for minimizing energy consumption of chemical plant by maximizing the utilization of hot and cold utilities available within the process, thereby reducing the use of external utilities. It is also known as process integration, heat integration, energy integration or Pinch technology. Pinch technology is applied on various process flow diagrams from chemical industries using different strategies or techniques. These techniques include both graphical procedure (Thermal Pinch diagram) as well as algebraic procedure (Temperature interval diagrams) in order to compare the minimum heating and cooling utility requirement of a process with the actual requirement. In the present work, the process flow diagram of finishing column section is received from a chemical industry and block diagram is prepared for simplification. The hot and cold streams are identified and Pinch analysis techniques are applied in order to find out the minimum heating and cooling utility requirement. With this, the utilities available within the process can be used better and thus energy can be conserved to an extent of 25%.Key words: Graphical procedure, Heat integration, Pinch Technology, Revised cascade diagram , Temperature interval diagram.

Mechanism of Boundary Lubrication and Wear of Frictionless Synovial JointAbstract: The natural synovial joints have excellent lubricating ability to provide very low frictional resistance and high wear resistance during various activities of human being. Synovial fluid is having mainly constituents of glycoproteins and phospholipids. Albumin adsorbs over globulin by hydrophobic bonding after formation of globulin coating on hydrophilic cartilage surface and phosphatidylcholine adsorbs over hydrophilic surface of albumin by the formation of phospholipid bilayer. Different interface of adsorbed proteins and phospholipids layer produces very low shear stress and produces the synovial joint highly slippery and frictionless. Still, synovial joints are effected by Osteoarthritis due to degeneration of cartilage surface. Due to very very slippery boundary lubrication of synovial joint, abrasive and adhesive sliding wear of cartilage surface is not possible. Present study describes the damage mechanism of articular cartilage on the basis of asperity fatigue model. As knee joint bear much more load than that of hip joint during walking, knee joint is early effected in Osteoarthritis. As gradually, cartilage surface detoriates loosing ultimate strength and modulus of elasticity, wear rate increases with aging of human being. It indicates ultimate result of Osteoarthritis at old age.Key words: Synovial joint, Boundary lubrication, Asperity fatigue wear, Osteoarthritis Reference [1] Charnley J, The lubrication of animal joints; Symposium on Biomechanics, Institution of Mechanical Engineers April, (1959) [2] Burgess S, critical characteristics and the irreducible knee joint; journal of creation, 13(2), 112–117, (1999) [3] McCutchen C W, The frictional properties of animal joints; Wear, 5, 1-17, (1962) [4] Davis W H, Lee S L and Sokoloff L, A proposed model of boundary lubrication by synovial fluid: structuring of boundary water; Journal of Biomechanical Engineering, 101, 185-192, (1979) [5] Hills B A and Crawford R W, Normal and prosthetic synovial joints are lubricated by surface-active phospholipid, a hypothesis; The Journal of Arthroplasty, 18, 499-505, (2003) Biswajit Bera |

International technology roadmap for semiconductors (ITRS) reports that ―when technology scales down leakage power dissipation may come to dominate total power consumption. So it's important and challenging task for low power designers in sub micron circuits. Multiplication is a fundamental operation in most arithmetic computing systems.Multipliers has large area, long latency and consumes considerable power. The innovative power gating schemes stacking power gating are analyzed which minimizes the power dissipation in submicron circuits. The overall view of this paper is to attain high speed, low power full multiplier with alternative logic cells that lead to have reduced power dissipation. Here the total multiplier architecture is designed sub micron technology and observed the power analysis.Key words: low power, submicron technology, ITRS.

Various error correction code are provided for improving data reliability. A Reed-Solomon code is quite suitable for burst errors, but in case of random errors, it has some difficulty. For MLC NAND flash memories, Bose- Chaudhuri-Hocquenghem (BCH) codes are frequently used. BCH codes provide flexible code length and variable range of error correcting capability. However, NAND flash memory systems process with the large size of data such as a page or a block unit.

The work forms an image processing pipeline, consisting of noise reduction, feature extraction by image segmentation morphological operations to extract the region of interest. The work is based on the simultaneous use of two segmentation techniques, CB region split and merge segmentation and Otsu's Thresholding to extract the area of brain containing tumor from the magnetic resonance imaging (MRI) of brain.It has been observed that the otsu's thresholding technique gives a better performance in terms of accuracy and diagnosing the complete tumor region from the MRI. The results of this study are quiet promising.Key words: Color Based Region Split and Merge, Otsu's thresholding method ,Segmentation Reference [1] Maintz, J. and Viergever, M. (1998).

A Numerical Analysis of Novel Liquid-Gas Jet EjectorAbstract: In this article, numerical investigations have been carried out on ejectors employing liquid as a motive fluid and air as the entrained fluid. A numerical model has been developed to predict the air entrainment rate taking into account: (i) the compressible nature of air, (ii) pressure drop for two-phase flow and (iii) losses due to changes in cross sectional area. The effects of gas velocity, liquid level in the suction chamber, nozzle diameter and throat diameter on the liquid entrainment, entrainment ratio (L/G), pressure drop, gas hold-up, mass transfer coefficient and interfacial area have been investigated. The simulated performance is compared with the available experimental data from the literature for validation. The entrainment rate predicted from the numerical model shows good agreement with the experimental values.Reference [1] P.H.M.R. Cramers, A.A.C.M.

Image Processing and AnalysisAbstract: This paper describes the basic technological aspects of Digital Image Processing. Basically, all image-processing operations can be grouped into three categories: Image Rectification and Restoration, Enhancement and Information Extraction. The former deals with initial processing of raw image data to correct for geometric distortion to calibrate the data radiometrically and to eliminate noise present in the data. The enhancement procedures are applied to image data in order to effectively display the data for subsequent visual interpretation. It involves techniques for increasing the visual distinction between features in a scene.Key words: digital Image, radio metrically, noise, multi spectral, pixels.

Security Enhancement Using Rsa Algorithm In Multicast ManetAbstract: In mobile ad hoc networks, an application scenario requires mostly collaborative mobility behaviour. The key problem of those applications is scalability with regard to the number of multicast members as well as the number of the multicast group. To enhance scalability with group mobility, we have proposed a multicast protocol based on a new framework for hierarchical multicasting that is suitable for the group mobility model in MANET. We propose a advanced privacy policy by using a secret key Transformation by using RSA algorithm in novel Secured Geographic Multicast Protocol (SGMP).

Optimizing Power Supply by Pwm Converter Based Shunt Connected Power Conditioners –Distribution Static CompensatorAbstract: Increasing automation in modern industry and deregulation has changed the requirements on Power Quality. Computer and process control equipment as well as drive converters are sensitive to deviations of the line voltage from the ideal sinusoidal. Voltage sags, harmonic distortion, flicker and interruption of power supply are the most common problems. In an increasing number of cases, where conventional equipment cannot solve these problems, PWM converter-based shunt connected Power Conditioners named DSTATCOM (Distribution Static Compensator) have been introduced. Energy storage added to the Power Conditioner provides even more flexibility in system operation and planning for utilities and industry.Index Terms: Power quality,SVC,Voltage Sag,Voltage swell Reference [1] S.V.

SVM Classification an Approach on Detecting Abnormality in Brain MRI ImagesAbstract: Magnetic resonance imaging (MRI) is an imaging technique that has played an important role in neuro science research for studying brain images. Classification is an important part in order to distinguish between normal patients and those who have the possibility of having abnormalities or tumor. The proposed method consists of two stages: feature extraction and classification. In first stage features are extracted from images using GLCM. In the next stage, extracted features are fed as input to SVM classifier. It classifies the images between normal and abnormal along with type of disease depending upon features. For Brain MRI images; features extracted with GLCM gives 98% accuracy with SVM-RBF kernel function. Software used is MATLAB R2011a.Key words: GLCM, Image retrieval, Feature Extraction, MRI, SVM classifier Reference [1] B. Scholkopf, S. Kah-Kay, C. J. Burges, F. Girosi, P. Niyogi, T.

Multipath Node-Disjoint Routing Protocol to Minimize End To End Delay and Routing Overhead for MANETsAbstract: Today, node-disjoint multipath routing becomes an essential technique in communication of packets among various nodes in network. Mobile ad hoc networks typically having the high mobility and frequent link failures, so multipath routing protocol is crucially important. In this paper, we proposed the multipath node-disjoint routing based on AODV protocol. This routing finds three node-disjoint routes from source to destination. The main goal is to discover multiple node disjoint paths with a low routing overhead during a route discovery, also improve the end-to-end delay and packet delivery ratio. The performance of the proposed protocol investigated and compared against the single path AODV and multipath NDMP-AODV protocols through simulation using .NET. Results have shown that the proposed multipath routing protocol outperforms both protocols in terms of routing overhead, end to end delay and packet delivery ratio.Key words: AODV, MANET, Multipath Routing, Node-disjoint Reference [1] M.

A Proposed Service Broker Policy For Inter Region Data Center Selection in Cloud EnvironmentAbstract: In 21st century Cloud computing is the boon for all who want to reduce upfront capital expenditure on hardware and software. Cloud computing provides software, infrastructure, platform and data storage on pay-as-you-use basis. Data centers located at different locations provide services to the users. Proper Data center selection is important for proper resource utilization and good response time. Existing service broker policies are used to find the closest and cheapest Data center from intra region. But in case of single Data center failure or temporary Data center down, data center selection is random for inter region. We have proposed a new policy to select the inter region data center based on number of users running on it. In this paper we want to show that this proposed policy gives better response time compare to existing service broker policy.Key words: cloud computing, service broker policy, cloud analyst, data center, user base Reference [1] Buyya, Rajkumar, et al.

Performance Optimization of Long Haul High Bit Rate Optical Fiber System with Dispersion Compensating FiberAbstract: In this paper the comparison of the performance characteristic of pre and post compensation is done to reduce the chromatic compensation. The transmission behavior of return-to-zero (RZ) and non return-to-zero is compared numerically and experimentally. Data at the rate of 10 Gb/s were transmitted over 2000-km standard single-mode fiber using an alternative compensation scheme in a recirculation loop with more than 100 km amplifier spacing. The pre-compensation and post-compensation scheme is proposed using DCF to reduce the chromatic dispersion at the transmitter end.

Increase in power consumption can cause serious stability problems in electric power systems if there are no ongoing or impending construction projects of new power plants or transmission lines. Additionally, such increase can result in large power losses of the system. In costly and environmentally effective manner to avoid constructing the new infrastructures such as power plants, transmission lines, etc., In response to the recently increased prices of oil and natural gas, it is expected that the electric power industry will undergo considerable and rapid change with respect to its structure, operation, planning, and regulation.Key words: Distributed Generation, DG technologies, harmonics, voltage stability Reference [1] A.A.Chowdhury, S.K.Agarwal, and D.O.Koval, "Reliability modeling of distributed generation in conventional distribution systems planning and analysis," IEEE Trans.

Improvement Of Load Transient Response Of A Buck Convertor Employing Peak Current Mode ControlAbstract: The paper investigates the effect of unity-gain output current- Feed forward in a peak-current-mode-controlled (PCMC) buck converter. A consistent theoretical basis is provided showing that the unity-gain feed forward can improve significantly the load invariance and transient performance of a PCMC buck converter. The non idealities associated to the scheme would, however, deteriorate the obtainable level of invariance. The non idealities can be maintained at acceptable level, and therefore, the scheme would provide a viable method to reduce significantly the load interactions as well as improve the load-transient response. The theoretical predictions are supported with comprehensive experimental evidence both at frequency and time domain as well as comparisons between three different buck converters.Key words: Buck converter, load–current feed forward, output impedance, peak-current-mode control (PCMC).

QR Codes are mainly used to convey or store messages because they have higher or large storage capacity than any other normal barcodes. The paper describes the relation QR Code and cryptography. Since QR Codes have fast response time and have large storage capacity, QR Codes can be used perfectly to send encrypted data (messages) to the receiver. This method will be suitable in any business house, government sectors, and communication network to send their encrypted messages faster to the destination.

Analyzing the Effects of Shadowing and Fading On the Performance of Ad Hoc Routing Protocols in MANETAbstract: Two-ray ground reflection model and FRIIS free-space model have been widely used as the propagation model to investigate the performance of ad hoc networks. But two-ray model is too simple to represent a real world network, that is, it neglects the obstacles of a propagation environment. The radio wave propagation model has a strong impact on the results of the simulation run. The more realistic models namely shadowing and fading propagation models have been used in this investigation. This paper shows the impact of shadowing and fading on the performance of several ad hoc routing protocols by utilizing a realistic shadow fading channel in MANET environmentKey words: mobile ad hoc network, fading, interference, shadowing, Qual Net 6.1.

Reduction Of Power Consumption And Area Occupation By Using Deterministic Test Pattern TechniqueAbstract: Deterministic Test Pattern Technique. Which is used to reduce the number of test Patterns to find out the faults and hence power consumption will be reduced and 100% fault coverage. Partial matching pattern allows the reduction of the number of patterns used for detecting the random pattern resistant faults. A Multiple control Sequence is used to guide the linear feedback shift register (LFSR) to generate these patterns at application time. The patterns generated by the LFSR reduce 25% of power consumption when compared to those patterns produced by a conventional LFSR. The main advantages of this method are reduction of the test data volume, require less time to test the application and its reusability for logic cores on a system-on-chip (SOC).Key words: Built in self-test (BIST), Linear feedback shift register (LFSR), random-pattern-resistant (RPR) faults, system-on-chips (SOCs).

Design and Implementation of a Bypass Zero Feed A Directly (BZ-FAD) Architecture for Low Power ApplicationsAbstract: In this paper, a low-power structure called bypass zero, feed A directly (BZ-FAD) for shift-and-add multipliers is proposed and implemented. The architecture considerably lowers the switching activity of conventional multipliers. The modifications to the multiplier which multiplies A by B include the removal of the shifting the B register, direct feeding of A to the adder, bypassing the adder whenever possible, using a ring counter instead of a binary counter and removal of the partial product shift. The architecture makes use of a low-power ring counter proposed in this work. Simulation results for 32-bit radix-2 multipliers show that the BZ-FAD architecture lowers the total switching activity up to 76% and power consumption up to 30% when compared to the conventional architecture. The proposed multiplier can be used for low-power applications where the speed is not a primary design parameter.Key words: Hot-block ring counter, low-power multiplier, low-power ring counter, shift-and-add multiplier, switching activity reduction.

Inline content">Performance Study on Diesel Engine Using Different Blends of Neem BiodieselAbstract: The developing countries like India were adversely impacted by the overexploitation of fossil fuels and continuing rise in global price of crude oil. Biodiesel is a fuel comprised of mono alkyl esters of long chain fatty acids derived from vegetable oils or animal fats. Biodiesel is reliable, renewable, biodegradable and regarded as a clean alternative fuel to reduce exhaust emissions. Vegetable oils have become more attractive for the production of biodiesel in the recent past owing to its environmental benefits and the fact that it is made from renewable resources. Biodiesel is produced by the transesterification of triglycerides of edible/non edible oils, and waste vegetable oils using methanol with alkaline catalyst NaOH/KOH.Key words: Biodiesel, Engine performance, Neem oil, Transesterification.

Adaptive Control of Angular Position & Angular Velocity for A DC Motor with Full State MeasureableAbstract: Adaptive control is the control method used by a controller which must adapt to a controlled system with parameters which vary, or are initially uncertain. Adaptive control is different from robust control in that it does not need a priori information about the bounds on these uncertain or time-varying parameters; robust control guarantees that if the changes are within given bounds the control law need not be changed, while adaptive control is concerned with control law changing themselves. In this paper the methods of adaptive control are used and explored on a pilot-scale hardware platform. A computer-aided design procedure is used to achieve the specifications, as part of the overall adaptive systems.Reference [1] S. Sastry and M.

Reduction Of PAPR Using HADAMARD SLM In SFBC MIMO-OFDM SystemAbstract: This paper contains the Hadamard Transform in the SLM for the reduction of high peak to average power ratio (PAPR) in MIMO-OFDM systems. In this technique, the input sequence is multiplied by a set of phase rotation vectors respectively and then applies the Hadamard Transform to the each resulting sequence based on SFBC. After that perform the Inverse Fast Fourier Transform in order to get the time domain signal. The equivalent SFBC encoding operations in the time domain for generating candidate signal sets is performed, where one with the lowest maximum PAPR is selected for transmission. The proposed method has lower computation complexity and reduces the PAPR. The experimental results shows that the PAPR reduction performance of Hadamard SLM technique and compare with the PIIM, SLM and with the Simplified SLM techniques.Key words: Multiple-input Multiple output (MIMO); orthogonal frequency division multiplexing (OFDM); peak-to-average power ratio (PAPR) reduction; space frequency block coding (SFBC); Selected mapping (SLM) and Polyphase interleaving and inverse method(PIIM).

Energy Optimization in Wireless Sensor NetworksAbstract: Wireless Sensor Nodes are generally having less memory and low battery life. Due to this constraint, we need a strong algorithm by which we can reduce the energy consumption. The main energy is utilized during sending of the data. Some part of energy is utilized in processing the data. In this paper, we will give another approach for reduced energy consumption. We will consider the cost of sending as well as processing. So, we will use short distance path as well as compression of the data to reduce the power consumption. Finally we will simulate this scenario by making a small simulator for 4 nodes.Key words: Wireless Sensor Network, Energy optimization, compression, efficiency Reference 1] Debmalya Bhattacharya and R.

Implementation of Soft Decision Low-Density Parity-Check Decoder for Bahl-Cocke-Jelinek-Raviv AlgorithmAbstract: In this paper we focus on the BCJR algorithm, and its prior estimate of the channel state information (CSI), In case of uncertainties during the estimation, overconfident posterior probability tends to mislead the performance of soft decoders. Our approach takes into consideration not only the uncertainty due to the noise in the channel, but also the uncertainty in the CSI estimate. Thus, we resort to a Bayesian approach for the computation of the APP. Hence, we also put forward an approximation for each symbol's posterior, using the expectation propagation algorithm, which is optimal from the Kullback- Leibler divergence.Key words: IR filters, expectation propagation, LDPC coding, ML-BCJR equalization, QPSK modulator, fading Channels.

MODELING OF SINGLE-PHASE TO THREE-PHASE DRIVE SYSTEM USING TWO PARALLEL CONVERTERS ON INPUT SIDEAbstract: The objective is to supply a three phase motors from a single phase AC mains. It is common to have only a single phase power grid in residential, commercial, manufacturing and mainly in rural areas, while adjustable speed drives may require a three phase power grid. Hence we need to convert from single phase to three phase supply to operate the drive system. Parallel converters can be used to improve the power capability, reliability, efficiency and redundancy. Parallel converter techniques can be employed to improve the performance of active power filters, uninterruptable power supplies, fault tolerance of doubly fed induction generators and three phase drives. When an isolation transformer is not used, the reduction of circulating currents among different converter stages is an important objective in the system design.Key words: Ac-dc-ac power converter, 3-phase Ac motor drive, parallel converter.

Effect of Torsion Consideration in Analysis of Multi Storey frameAbstract: At present scenario many buildings are asymmetric in plan and/or in elevation based on the distribution of mass and stiffness along each storey throughout the height of the building. Most recent earthquakes have shown that the irregular distribution of mass, stiffness and strengths may cause serious damage in structural systems.Torsional behavior of asymmetric building is one of the most frequent cause of structural damage and failure during strong ground motions. In this work a study on the influence of the torsion effects on the behavior of structure is done. In building two cases are considered, case one is without considering torsion and case two is considering torsion.

The advantages of the proposed framework stem from the following: 1) a simple approach to support the assessment of the current condition of defects associated with gravity sewer pipelines; 2) a Markov chain approach for prediction of future conditions along the planning horizon; and 3) a GA-based optimization algorithm for determining the least-cost strategy to repair pipeline deficiencies in each year of the planning horizon. A case study of Shoha sewer network in Dakhlia, Egypt is presented to demonstrate the capabilities of the developed frame work. The results showed the effectiveness of the proposed framework in making appropriate decisions that ensure the sustainable operation of sewer pipelines networks.Reference [1] ASCE, (1994), Existing Sewer Evaluation and Rehabilitation, ASCE Manuals and Reports on Engineering Practice No. 62.

Designing CNTFET and Force Stacking CNTFET Inverter for the Analysis of Average Power and PDP at Different Low Supply VoltageAbstract: As technology scales down to 90nm and below, the bulk CMOS technology has approached the scaling limit due to the increased short-channel effects, increased leakage power dissipation, severe process variations, high power density, and so on. To overcome this scaling limit, different types of materials have been experimented. Si-MOSFET-like Carbon nanotube FET (CNFET) devices have been evaluated as one of the promising replacements in the future nanoscale electronics. CNFET has lower short-channel effect and a higher sub-threshold slope than Si-MOSFET .It has been observed that the stacking of two off devices has smaller leakage current than one off device. this paper propose an inverter that uses forced stack technique to reduce average power and PDP. circuit is simulated using HSPICE with Stanford CNFET model at 32nm. The simulation result shows that the proposed forced stack CNTFET inverter reduce average power by 15% when supply voltage is 0.9v ,13.204% when supply voltage is 0.8v and 13.116% when supply voltage is 0.7v.Key words: Average Power, CNTFET, Force Stacking, HSPICE, PDP Reference [1] ITRS, Process Integration, Devices, and Structures,http://www.itrs.net/Links/2009ITRS/2009Chapters_2009Tables/2009_PIDS.pdf, 2009.

A Preliminary Study and Analysis on Hidden Markov Model (HMM) Using PCA Techniques for Face RecognitionAbstract: Nowadays preparing an effective model for face recognition is difficult task. Face is a critical and complex multidimensional visual model. However in this Article, we present a method for face recognition based on Hidden Markov Model (HMM) and it has been widely used in various fields such as in speech recognition, gesture recognition and so on. We proposed this approach basically current face recognition techniques are dependent on issues like background noise, lighting and position of key features (i.e. the eyes, lips etc.).Moreover the face patterns are divided into numerous small-scale states and they are recombined to obtain the recognition result. Our experimental results shows that the proposed method has been achieved 96.5% recognition accuracy for 400 patterns of 40 Subjects i.e. 40 classes of which each class contains 10 patterns each. Apart from these results we did some comparative analysis with PCA. Over observations stated that the performance of HMM based face-recognition method is better than the PCA for face recognition.Key words: Pattern Recognition, preprocessing, Hidden Markov Model, PCA Based Face Recognition.

Single Layer Symmetrical Y-Slots Wideband Microstrip Antenna Using IE3DAbstract: Microstrip patch antennas are strong candidates for use in many wireless communication applications. The proposed antenna design approach is based on a single-layer, square patch (Length=30mm and Width=30mm) with two symmetrical Y-slots and a rectangular slot on the patch with coaxial probe feed to achieve wide band application with very low return loss. The proposed antenna is modeled using IE3D electromagnetic (EM) simulation packages namely IE3D from Zeland. The objective of this paper is to design, construct and fabricate microstrip antennas suitable for wireless application that centered at frequency 4.87 GHz. The antenna must operate within the band of 4.04GHz to 5.12GHz band. This band is currently being used for industrial, medical and scientific applications. The antenna is proposed to be used as a transmitting as well as receiving antenna in wireless network and the mentioned applications. A thick substrate FR4 which has a dielectric constant 4.4 with infinite ground broadens the bandwidth of the antenna. The proposed antenna reduced the return loss as well as increases the bandwidth of the antenna.Key words: Microstrip antenna, Wide band.

They are used to study the impact of drive current, pump-signal detuning, input pump and signal powers on wavelength conversion process. In particular, the issue of optimum input pump and signal powers and range of assist beam is studied. We investigated the conversion efficiency (CE) and optical signal to noise ratio (OSNR) properties of ASE-assisted FWM in Semiconductor optical amplifier and demonstrated that in the presence of high internal Amplified Stimulated Emission, the requirement on input optical powers for wavelength conversion is reduced from 10s of mWs to less than 1 mW.

Finite Element Analysis on Rapid Prototyping Pattern with Different InternalStructure for Investment CastingAbstract: Manufacturing a metal product with complex geometry usually will related to Investment Casting (IC) process as the process has the highest capability to deliver the intended objective. But producing the wax pattern for the process has already consumes half of the time of overall process. Rapid Prototyping (RP) is considered to be a solution as it capable to reduce the time in a large margin. Compared to wax patterns traditionally made for IC, RP patterns mainly built from polymer based material. Polymer may react differently than wax when it comes to the burnout process which is a critical part in IC that determines the quality of the final cast product. By considering both strength and collapsibility, cube pattern with different internal structure designs were developed using SolidWorks software and analysis by ANSYS software. All designs were tested for total deformation and equivalent Von Misses stress within the temperature range from room temperature of 27ºC up to 700ºC.Key words: Acrylate, Finite Element Analysis, Investment Casting, Multi-Jet Modeling, Rapid Prototyping Reference [1] W.S.W.

High Throughput Two- Dimensional Median Filters On FPGA for Image Processing ApplicationsAbstract: An efficient hardware implementation of a median filter is presented. Input samples are used to construct a cumulative histogram, which is then used to find the median. The resource usage of the design is independent of window size, but rather, dependent on the number of bits in each input sample. This offers a realizable way of efficiently implementing large-windowed median filtering, as required by transforms such as the Trace Transform. The method is then extended to weighted median filtering. The Median filter is an effective method for the removal of impulse-based noise from the images. This paper suggests an optimized architecture for filter implementation on FPGA. A 3x3 sliding window algorithm is used as the base for filter operation. Partial implementation is done via soft core processor. The designs are synthesized for a Xilinx Spartan-3 EDK.Key words: FPGA, Median Filter, Soft Processor Core, Parallelism, Pipelining Reference [1] M. Karaman, L. Onural, and A.

Efficient Performance of Lifting Scheme Along With Integer Wavelet Transform In Image CompressionAbstract: In image compression using transform techniques the purpose is to reduce the data redundancy significantly, both spatial and spectral, without affecting the quality of the picture much.A lossless reversible image compression model is proposed for both continuous and discrete time cases, that exploits integer wavelet transform(IWT) employing lifting scheme(LS).Unlike its conventional counterpart in wavelet decomposition ,here both approximation as well as detailed image contents are splitted providing better compression ratio. Adequate use is made of both forward and inverse lifting schemes so as to reduce the computational complexity by a factor of two and achieve superior compression performance in terms of encoding time, decoding time,peak signal to noise ratio PSNR and better compression ratio(CR). Bi-orthogonal wavelets are constructed using lifting scheme that makes optimal use of both high pass and low pass filter values, and consequently addition and shift operations are performed on the resulting wavelet coefficients. This paper projects the advantages of IWT using LS used in real time compression of both still and color images involving non smooth domains or curves.Key words: IWT, LS, PSNR, CR, DWT, Bi-orthogonal wavelets.

Analysis of Optimization of Blank Holding Force In Deep Drawing By Using LS DYNAAbstract: Sheet metal forming problems are typical in nature since they involve geometry, boundary and material non-linearity. Cup drawings involves many parameters like punch and die radius, clearance, lubrication, blank holding force and its trajectories etc. So designing the tools for cup drawing involves a lot of trial and error procedure. To reduce number of costly trial error steps, the process can be simulated by using finite element packages. Even the finite element package gives an approximation towards the solution. The experimentation is inevitable. The aim is to study analysis of optimization of blank holding force developed for cup drawing operation by using explicit finite element package LS DYNA. One of the basic problems in deep drawing is wrinkling. Wrinkling can be avoided by using blank holding force. But higher the blank holding force (BHF), higher is the frictional force, so more will be tensile stresses in cup wall there by promote tearing failure at the punch corner. Hence BHF needs to optimized so as to prevent the wrinkling and at the same time to prevent tearing failure.Key words: Deep Drawing by Using LS DYNA, Blank Holding and blank holding force (BHF).

An Enhanced ZVS & ZCS Full Bridge Converter With Resonance Circuit In The Secondary Winding For High Power ApplicationsAbstract: A zero voltage and zero current switching full bridge converters with a resonance circuit in the secondary winding is presented analyzed. The primary side of the converter is composed of FB insulated-gate bipolar transistors, which are driven by phase-shift control. The secondary side is composed of a resonant tank and a half-wave rectifier. Without an auxiliary circuit, zero-voltage switching (for leading-leg switches) and zero-current switching (for lagging-leg switches) are achieved in the entire operating range. To implement the converter without an additional inductor, the leakage inductance of the transformer is utilized as the resonant inductor. Due to its many advantages, including high efficiency, minimum number of devices, and low cost, this converter is attractive for high-voltage and high-power applications. The analysis and design considerations of the converter are presented. A prototype was implemented for an application requiring a 5-kW output power, an input-voltage range varying from 250 to 350 V, and a 350-V output voltage. The experimental results obtained from a prototype verify the analysis. The prototype's efficiency at full load is over 95.5%.Key words: Reference [1] X. Wu, J. Zhang, X. Ye, and Z.

Redundant Wavelet Transform Based Image Super ResolutionAbstract: The process of Super Resolution (SR) aims at extracting a high resolution image from low resolution image. The proposed technique uses Redundant Wavelet Transform to enhance the resolution of an image using a single low resolution image. The proposed method decomposes the input image into different subbands. Then all subbands are interpolated. Combining all the interpolated subbands using Inverse Redundant Wavelet Transform provides the proposed super resolution image. The algorithm is tested with various wavelet types and their performance is compared. The proposed technique has been tested on Lena, Elaine, Pepper, and Baboon images. The proposed method gives higher quantitative peak signal-to-noise ratio (PSNR) and visual results in comparison to other conventional and state-of-art image Super resolution techniques.Key words: Image Super Resolution, Interpolation, Discrete Wavelet Transform, Redundant Wavelet Transform.

A New And Secure Chaos Based Multimedia Encryption SchemeAbstract: There has been a sudden rise in the usage of Multimedia data in the digital world. Be it images, videos or audios, there has been a high demand in their usage and transfer. Lots of applications are based on this type of Multimedia data. And this gives rise to the need for their protection. Data security has seen many types of traditional algorithms for the protection purpose but they have struggled to combat multimedia data as compared to regular textual data. A separate group of Algorithms based on Substitution-Permutation techniques have been used widely in the security. This paper proposes a scheme based on a new permutation technique and chaos based substitution method. The scheme works well on normal as well as highly redundant images. Various types of attacks like statistical, differential and visual have been performed on the algorithm and observations have been reported.

Performance of Induction Motor Using 3-Level Cascade InverterAbstract: This paper presents performance analysis of induction motor using 3-level cascade inverter. Many schemes have been proposed for the speed control of induction motor drives, among which the indirect vector control is most effective method. An indirect vector controlled induction motor drive performance is poor with two-level inverter. To overcome these problems three-level cascade inverter is used. Space vector pulse width modulation (SVPWM) method is employed to control three-level cascade inverter. Conventional indirect vector control of induction motor drive uses hysteresis current controller, which causes variable switching frequency of the inverter. We can overcome this problem using SVPWM algorithm. To validate the proposed system, simulation studies have been carried out on vector controlled induction motor drive and the results are presented in this paper.Key words: 3-level cascade inverter, SVPWM, Indirect vector control.

Comparative Study: Detection of Shadow and Its RemovalAbstract: The presence of shadows has been dependable for reducing the trustworthiness of many computer vision algorithms, including segmentation, object detection, scene analysis, tracking, etc. Therefore, shadow detection and removal is a significant pre-processing for improving performance of such vision tasks. This work performs comparative study for three representative works of shadow detection methods each one selected from different category: the first one based on to derive a 1-d illumination invariant shadow-free image, the second one based on a hypothesis test to detect shadows from the images and then energy function concept is used to remove the shadow from the image. In this paper, we use the transformation of the gradient field for edge suppression which will result into the removal of the shadow from an image.Key words: Cross -Projection tensors, Energy Function, Gradient field transformation, illuminant in- variance, Shadow Removal.

Design Of Low Power &Energy Proficient Pulse Triggered Flip-FlopsAbstract: In this paper, pulse-triggered flip-flop types which are bidirectional elements in sequential logic circuits were designed. Initially, the pulse generation control logic is removed from the critical path to facilitate a faster discharge operation. Following low-power techniques are implemented, such as conditional capture, conditional precharge, conditional discharge, conditional data mapping, clock gating technique and SAL technique. Among all the mentioned techniques, SAL technique is the best one to avoid internal switching activities to reduce power dissipation, and also proposed circuit can be estimated as free of glitches. This paper explores the energy-delay space of widely referred flip-flops in a 180nm CMOS technology.Key words: Flip-Flop, Low Power, Pulse triggered, clock gating, SAL technique.

The main parameter on which uniformity depends is Radial force, lateral force, and conicity. We have taken value of all three parameter of six hundred tyres and found the relative variation of all with respect to the run out temperature of tyre. We found by the analysis that variation in LC is uneven. And on the other hand variation of RC & CONICITY with in rang. Hence a needful work is required to control the variation of "LC". With all these regration modally has also been done. To get the relation of LC, RC, CONICITY with the run out temperature.

Its primary function is to transmit the push and pull from the piston pin to the crank pin, thus converting the reciprocating motion of the piston into rotary motion of the crank. Existing Bearing of connecting rod is manufactured by using non ferrous materials like Gunmetal, Phosphor Bronze etc.. This paper describes the tribological behavior analysis for the conventional materials i.e. Brass and Gunmetal as well as New non metallic material Cast Nylon.

Variable Workload Scheduling With Increased Throughput in Wireless Sensor NetworksAbstract: Wireless sensor networks are appealing to researchers due to their wide range of application potential in areas such as target detection and tracking, environmental monitoring, industrial process monitoring, and tactical systems. Existing approaches are insufficient for developers to determine whether system's requirements concern the communication latency, bandwidth utilization, reliability, or energy consumption. Since the data of sensors are expressed in form of expressive queries, the performance of query services should be increased especially for high data rate sensor network applications. In this paper it is decided to propose Real Time Conflict-free Query Scheduling (RTCQS), an enhanced transmission scheduling technique for real time queries in wireless sensor networks. The query preemption algorithm is used to achieve high throughput while scheduling without preemption is used for the queries that are able to execute concurrent.Key words: Wireless Sensor Networks, throughput, Scheduling, Interference-Communication graph, Inter release time Reference [1] I.

An Intrusion Detection Using Hybrid Technique in Cluster Based Wireless Sensor NetworkAbstract: Wireless Sensor Networks (WSNs) are playing a fundamental role in emerging pervasive platforms that have potential to host a wide range of next generation civil and military applications. Wireless sensor network (WSN) is regularly deployed in unattended and hostile environments. The WSN is vulnerable to security threats and susceptible to physical capture. Thus, it is necessary to use effective mechanisms to protect the network. Intrusion detection system is one of the major and efficient defensive methods against attacks on wireless sensor network. Sensor networks have different characteristics and hence security solutions have to be designed with limited usage of computation and resources.Key words: Wireless Sensor Network, Rule-based & cluster-based intrusion detection, Hybrid, Anomaly detection.

Implementation of Music Algorithm for Smart Antenna SystemAbstract: Adaptive antenna arrays use multiple antenna elements to form directional patterns in order to improve the performance of wireless communication systems. The direction-of-arrival estimation is a crucial component of the smart antenna system. Smart antenna system is based on digital signal processing algorithms. The smart antenna system becomes capable to locate and track signals by the both: users and interferers and dynamically adapts the antenna pattern to enhance the reception in Signal-Of-Interest direction and minimizing interference in Signal-Of-Not-Interest direction. In adaptive array smart antenna, various Direction Of Arrival (DOA) estimation algorithms are used to locate the desired signal. Direction-of-arrival (DOA) estimation is based on the MUSIC algorithm for identifying the directions of the source signals incident on the sensor array comprising the smart antenna system.Key words: Adaptive array, DOA estimation, MUSIC, Smart antennas.

Single Event Upset (SEU) in SRAMAbstract: Radiation in space is potentially hazardous to microelectronic circuits and systems such as spacecraft electronics. Transient effects on circuits and systems from high energetic particles can interrupt electronics operation or crash the systems. This phenomenon is particularly serious in complementary metal-oxide-semiconductor (CMOS) integrated circuits (ICs) since most of modern ICs are implemented with CMOS technologies. The problem is getting worse with the technology scaling down. Radiation-hardening-by-design (RHBD) is a popular method to build CMOS devices and systems meeting performance criteria in radiation environment. Single-event transient (SET) effects in digital circuits have been studied extensively in the radiation effect community.Key words: linear energy transfer (LET), single event upset (SEU), single event error (SEE), single event transient (SET) Reference [1] L.

Comparison and Analysis of Pro-Active Routing Protocols in MANETAbstract: Mobile Ad hoc wireless networks are characterized by infrastructure less environment, multi-hop wireless connectivity and frequently changing topology. Wireless links are highly error prone and can go down frequently due to mobility of nodes. So stable routing is a very critical task due to highly dynamic environment in ad-hoc wireless networks. The identification of stable and efficient routing protocol plays a very critical role in places where wired network are neither available nor economical to deploy. In this paper, comparison and behavioral study of different MANET pro-active routing protocols such as DSDV, WRP, CGSR, GSR, DREAM, STAR, HSR, TBRPF, FSR, LANMAR, OLSR, and HOLSR have been carried out so as to identify which protocol is most suitable for efficient routing over mobile ad-hoc network (MANET). This paper provides an overview with advantages and disadvantages of these pro-active routing protocols by presenting their comparative analysis.Key words: DSDV, WRP, LANMAR, CGSR, FSR, OLSR, HOLSR.

Effect Of Magnet And Oil Damper On Reduction Of Seismic Response Of HousesAbstract: It is important to reduce the seismic response of houses in order to prevent from collapse of houses. Some control methods for seismic response of houses are developed. The oil dampers using the flow resistance of the silicon oil have been developed. In this paper, a Magnet Oil Damper (MOD) in which permanent magnets are added to the oil damper is proposed in order to improve the performance of the oil damper. MOD is installed in two-story house. The effect of MOD is examined experimentally. The peaks of resonance curves are reduced when MOD is used. The effectiveness of MOD is examined by numerical simulation using the analytical model. The response of the house subjected to actual earthquake excitation decreases when MOD is used.Key words: Damper, Earthquake resistant, Forced vibration, Frequency response function, Seismic motion Reference [1] Othman,A.B., Property Profile of a Laminated Rubber Bearing, Polymer Testing, 20(2), 2001, 159-166.

Color Space-Time Interest Points for Live FeedAbstract: Interest point detection is the vital aspect of computer vision and image processing. Interest point detection is very important for image retrieval and object categorization systems from which local descriptors are calculated for image matching schemes. Earlier approaches largely ignored color aspect as interest point calculation are largely based on luminance. However the use of color increases the distinctiveness of interest points. Subsequently an approach that uses saliency-based feature selection aided with a principle component analysis-based scale selection method was developed that happens to be a light-invariant interest points detection system. This paper introduces color interest points for sparse image representation. In the domain of video-indexing framework,interest points provides more useful information when compared to static images.Key words: Interest points, Scale selection, image retrieval, STIP, LoG, Object Categorization Reference [1] R.

Efficient Artificial Immune Algorithm for Preventive-Maintenance-Planning For Multi State SystemsAbstract: In this paper we use an artificial immune optimization algorithm in conjunction with the universal generating function (UGF) to solve the preventive maintenance (PM) problem for multistate series-parallel system. In this work, we consider the situation where system and its components have several ranges of performance levels. Such systems are called multi-state systems (MSS). To enhance system availability or (reliability), scheduled preventive maintenance actions are performed to equipments. These PM actions affect strongly the effective age of components and increase system reliability. The MSS measure is related to the ability of the system to satisfy the demand. The objective is to develop an algorithm to generate an optimal sequence of maintenance actions for providing a system working with the desired level of availability or (reliability) during its lifetime with minimal maintenance cost. To evaluate the MSS system availability, a fast method based on UGF is suggested. The immune algorithm (IA) approach is applied as an optimization technique and adapted to this PM optimization problem.Key words: Universal generating function, Immune algorithm, Optimization, Preventive Maintenance Reference [1] D.

Physico-Chemical Properties of the Biodiesel Extracted From Rubber Seed Oil Using Solid Metal Oxide CatalystsAbstract: Physicochemical properties of the commercially procured rubber seed oil (RSO) were studied to evaluate its potential as viable feedstock for biodiesel production. The procured rubber seed oil were characterized for acid value, saponification value, free fatty acid, flash point, kinematic viscosity, and refractive indices using standard methods. Results indicate that the procured rubber seed oil is a potential biodiesel feed stocks and it is possible to convert this to biodiesel with a single stage process. The trans-esterification reactions were carried out in the presence of a solid metal oxide catalyst, calcium oxide (CaO) and the yield estimated was around 98%.The quality of the biodiesel produced was comparable with that of the petro diesel which indicates that this can be blended with the commercial petro diesel. The calorific value and cetane number of this biodiesel was higher than that of the petro diesel which indicates that the blending may increase the fuel efficiency as well.Key words: Biodiesel, Rubber seed oil, Solid metal oxides, Catalysts Reference [1] Jacobson K, Gopinath R, Meher LC, Dalai AK.

An Enhanced Low Bit Rate Audio Codec Using Discrete Wavelet TransformAbstract: Audio coding is the technology to represent audio in digital form with as few bits as possible while maintaining the intelligibility and quality required for particular application. Interest in audio coding is motivated by the evolution to digital communications and the requirement to minimize bit rate, and hence conserve bandwidth. There is always a tradeoff between lowering the bit rate and maintaining the delivered audio quality and intelligibility. The wavelet transform has proven to be a valuable tool in many application areas for analysis of nonstationary signals such as image and audio signals. In this paper a low bit rate audio codec algorithm using wavelet transform has been proposed.Key words: Audio coding, MATLAB 7.5, DWT, DWPT, Post-Filter. Reference [1].

Framework for Multi-Cloud Using Integrity Verification Using CPDP SchemeAbstract: Provable data possession (PDP) is a technique for ensuring the integrity of data in storage outsourcing. In this paper, we address the construction of an efficient PDP scheme for distributed cloud storage to support the scalability of service and data migration, in which we consider the existence of multiple cloud service providers to cooperatively store and maintain the clients' data. We present a cooperative PDP (CPDP) scheme based on homomorphic verifiable response and hash index hierarchy. We prove the security of our scheme based on multi-prover zero-knowledge proof system, which can satisfy completeness, knowledge soundness, and zero-knowledge properties. In addition, we articulate performance optimization mechanisms for our scheme, and in particular present an efficient method for selecting optimal parameter values to minimize the computation costs of clients and storage service providers. Our experiments show that our solution introduces lower computation and communication overheads in comparison with non-cooperative approaches.Key words: Storage Security, Provable Data Possession, Interactive Protocol, Zero-knowledge, Multiple Cloud, Cooperative Reference [1].

Design of an Implicit Pulse Triggered Flip-Flop Using PTL Based and Logic for Space Applications.Abstract: In this paper, a novel low-power pulse-triggered flip-flop (FF) design for space applications is presented. In this the clock generation circuitry an AND function is removed and is replaced with a Pass-Transistor logic based AND gate. Since in the PTL-style AND gate the n-mos transistors are in parallel they consume less power and provides a faster discharge of the pulse resulting in miniaturization and power consumption reduction in satellites. A software package called the TANNER EDA tools utilizing MOSIS 90nm technology is used for the study.Key words: Flip-flop, low power, pulse-triggered Reference [1] Yin-Tsung Hwang, Jin-Fa Lin, and Ming-Hwa Sheu, 2012, "Low-Power Pulse-Triggered Flip-Flop Design With Conditional Pulse-Enhancement Scheme," Proc IEEE Transactions on Very Large Scale Integration (VLSI) Systems, Vol. 20, No. 2, pp. 361-366.

Dielectric Studies Of Manganese Carbonate NanocrystalsAbstract: Over the past few years, the synthesis and characterization of nanocrystals of materials have become an area of intense research activity. MnCO3 (Manganese Carbonate) is a well known semi conducting material and is highly useful in electronic and optical devices. In the present study, we have made an attempt to prepare MnCO3 (with two different ratios of preparation) with simple domestic microwave assisted solvothermal method. The samples were characterized by TGA analysis. The particle size determination was done using the XRD pattern. The dielectric studies were carried out. The present study indicates that the polarization mechanism in the nano crystals considered is mainly contributed by the space charge polarization. It can be understood that the space charge contribution plays in important role in the charge transport process and polarizability in all the systems considered in the present study.Key words: Manganese corbonate, solvothermal method, dielectric measurements Reference [1] C.D.

An Enhanced Security Technique for Storage of Multimedia Content over Cloud ServerAbstract: Cloud computing is an emerging computing paradigm in which resources of the computing infrastructure are provided as services of the internet. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. With the development Internet multimedia computing has emerged as a technology to generate, edit, process, and search media contents, such as images, video, audio, graphics, and so on. Multimedia cloud computing has the potential for tremendous benefits, but wide scale adoption has a range of challenges like Multimedia and service heterogeneity, QoS heterogeneity, Network heterogeneity, Device heterogeneity ,Security, Power Consumption that must be met. But data security and access control is the main challenge when users outsource sensitive data for sharing on cloud servers which is not within the same trusted domain as data owners. To keep sensitive user data confidential against untrusted servers, various methods have been proposed in the literature. This paper explores a new method which is a combination of roll based access control with advanced encryption algorithm (a combination of RSA and two fish),signature verification to enhance security when storing text, image ,audio ,video files onto cloud server.Key words: cloud, multimedia, RSA, security, storage.

Understanding the Differences between Proprietary & Free and Open Source SoftwareAbstract: Proprietary software is the one which is owned by an individual or a company. They are almost always major restrictions on its use, and its source code is always kept secret. Examples include the products delivered by Microsoft, the Windows family of operating systems and Microsoft office. On the other hand Open source software has recently become a major interest in the software industry. Open source software includes free software and public domain software. Open source software generally same as free software is available at no or with limited cost to everyone along with the source code, and it can be used by any one for any purpose and with minimal restrictions. In this paper we would like to focus some of the differences between the Proprietary and Open source software in general terms and in particular in terms of their evolution, verifiability of Lehman laws of software evolution, Style of development, the participants in the development and evolution and the differences in the users' perspective.Reference [1] Software Evolution – Tom Mens, Serge Demeyer-Springer-2008 [2] Three Strategies for Open Source Deployment: Substitution, Innovation and Knowledge Reuse- Jonathan P.Allen: IFIP International Federation for Information Processing [3] Open-Source Vs Proprietary Software Jean-Michel Dalle, Nicolar Jullien [4] The Linux kernel as a case study in software evolution: Ayelet Israeli,Dror G.

Performance Modeling and Analysis for Dynamic Bandwidth Distribution Scheme Using Real-Time Probabilistic SystemAbstract: The passive optical network (PON), with its inherent point to multi-point structure, allows for centralized placement of active equipment and possible extension of its boundary towards core networks. This property of the PON can be exploited for node consolidation where multiple central offices are replaced by a single one covering a larger service area. Such node consolidation is being particularly driven by the need for network operational cost saving, and is offering significant challenges to PONs. The degree of node consolidation that can be achieved is limited by the reach of conventional PON systems. In order to achieve a larger degree of node consolidation, an extension of the PON reach, beyond the conventional 20 km, is required. This article addresses the challenges of the dynamic bandwidth allocation (DBA), where increased reach results in a degradation of DBA performance and quality of service support.Key words: Passive optical network; dynamic bandwidth allocation ; Real Time Probabilistic Systems; performance analysis.

Operation Improvement of an Indoor Robot by Using Hand Fingers RecognitionAbstract: Processing Real-Time image sequence is now possible because of advancement of technological developments in digital signal processing, wide-band communication, and high-performance VLSI. Recently, the demand for the indoor robots has increased. Therefore, increased opportunities for many people to operate the robots have emerged. However, for many people, it is often difficult to operate a robot using the conventional methods like remote control. To solve this problem, we propose a robot operation system using the hand gesture recognition. Our method pays attention to the direction and movement of the hand. We were able to recognize several gestures in real-time.Reference [1] Toshiya YAMADA, Kazunori UMEDA: Improvement of the Method of Operating a Mobile Robot by Gesture Recognition, http://www.mech.chuou.ac.jp/umedalab/publications/pdf/intro/yamada.pdf [2] Yuuji ASADA, Isao NISHIHARA, Shizuo NAKANO : A study of recognizing movement in hand gesture interface using processing, ITE Technical Report Vol.34 No.18 (2010) [3] Yohei SATO, Kokichi SUGIHARA :An approach to real-time gesture recognition for human-PC interaction Guide to the Technical Report and Templete, TECHNICAL REPORT OF IEICE NLC2004-112 (2005) [4] Kenichi FUKAYA : Manipulating a Mobile Robot by Hand Gestures, Hokkai-Gakuen University Fig.15 categorize 2 [5] G.

Pricing Of System Security through Opf and Scopf Methods with N-1 Contingency Criteria in Deregulated Electrcity MarketAbstract: This work involves with a system pricing for power system security in deregulated electricity market that includes security constraints in a multi objective OPF problem. The most common target function in the classical formulation of the OPF is minimization of generation costs. The OPF increases social benefit, as well as the distance from the voltage collapse point. The effect of N-1Contingency on pricing is analyzed. The Day-ahead energy market is a financial market that enables market participants to purchase and sell energy at binding Day-ahead prices. The market participants bid according to their marginal price and market clearing price is decided by matching the generation and demand side bidding. ATC is computed by Linear Analysis method, considering N-1 contingency. The ATC shows amount of congestion. TTC is calculated offline. Application of the proposed method on IEEE 30-bus standard network confirms its validity and effectiveness.Index Terms: Security constraints, TTC, ATC, Contingency Analysis, OPF and SCOPF.

Analysis of Air Jet RefrigerationAbstract: The Air Jet Refrigeration is based on the Bernoulli's equation across a streamline. Here a jet of air is used to cool the water when passed through the reducing section with the help of fan. The cooling effect takes place due to the suction pressure created at the throat when the jet of air is passed through the reducing section. Due to high velocity of air, the appropriate suction pressure is created and air takes latent heat of water and water gets cooled.Key words: Bernoulli's principle, suction pressure, coefficient of performance, reducer Section.

Incremental Conductance MPPT Method For Photovoltaic SystemAbstract: Solar power being a renewable energy resource has tremendous potential of usage in the imminent future and this paper is going to discuss an effective strategy to maximize solar energy harvest. This study has been done using MATLAB/Simulink combining solar modules, incremental conductance MPPT algorithm block and boost converter control block. Though solar energy harvest is dependent of irradiance, temperature and other climatic conditions it is imperative that a photovoltaic system operates at a maximum power point (MPP) in order to extract maximum energy from the system. The incremental conductance algorithm is an energy optimization strategy that provides fast dynamic response and well regulated photovoltaic (PV) output voltages. In addition, the number of parameter needed to be monitored are significantly lower than other algorithms, making the implementation much more streamlined and cost effective. This paper is going to discuss the observations of maximum power point tracking implemented on a solar power grid, thus augmenting its efficiency.Key words: perturb-and-observe, maximum power point tracking, incremental conductance, boost converter.

Tribological Investigation of Mahua Oil Based Lubricant for Maintenance ApplicationsAbstract: Limited crude reserves, consistently rising oil prices, unsafe disposal of the harmful lubricants and its guaranteed adverse aftereffects has increased concern for replenishing the environment. Development of environmental friendly lubricants and its appropriate usage is an option of prime importance which can overcome such problems. This paper investigates the prospects of Mahua oil based lubricant for maintenance applications. Mahua oil is blended with conventional gear oil (90T) in different ratios. Tribo pair used is plain carbon steel cylindrical pin and mild steel disc . Friction and wear parameters have been studied on Pin on Disc Tester under varying conditions. Worn out pins suggests pronounced abrasive and adhesive wear pattern under boundary film lubricated conditions. Experimentation reveals that addition of mahua oil blended with 90 T oil has good wear reducing traits apart from environmental benefits.Key words: Mahua Oil, Bio-Lubricant, Non-Edible Vegetable Oil, Mineral Oil, Blending, Viscosity Reference [1] Theo, Mang ,W.

Kerberos Based Emergency Services SystemAbstract: The Emergency services numbers are widely used in different countries, It is a three-digit number, which is used for different emergency services like ambulance, police and fire. Some countries are having a single emergency number for all emergency services and there are also some other countries which are having different emergency numbers for different emergency services. The popularity of these emergency numbers are increasing day by day, due to this popularity, fake emergency calls or prank calls or hang-up calls are also increasing and such type of calls are not only a wastage of time but also wasting lots of emergency resources and because of false calling many times the needed people are not able to get the emergency services and in many countries these fake calls are very common because there is no provision of giving punishment on fake calling.Key words: Authentication Server (AS), Kerberos, Kerberos Based Emergency Services System (KBESERV), Subscriber Identity Module (SIM Card).

| 376. | Digital Simulation Of Current Fed Quasi - Z Source Inverter
Digital Simulation Of Current Fed Quasi - Z Source InverterAbstract: Quasi-Z Source Inverters (qZSIs) are an improvement to traditional Z Source inverters (ZSIs). The advantages of qZSIs include different combinations of: lower component ratings, reduced source stress, reduced component count and simplified control strategies. The conventional current-source inverter (CSI) has two major problems: unidirectional power flow and voltage boost operation, which make it impossible to be used in many applications such as hybrid electric vehicles and general-purpose variable-speed motor drives. ZSIs can solve above problems with a limitation of boosting up the output current levels. This can be overcome with the proposed Current-fed quasi-impedance source inverter. This paper presents a comprehensive study on the new features of current-fed qZSI, which include the advantageous like boost function, improved reliability and reduced passive component ratings.Key words: Current-source inverter (CSI), voltage-source inverter (VSI), Z - Source inverter (ZSI), Current fed quasi Z Source inverter (qZSI).

Sparse Audio Tampering Based On Compressive SensingAbstract: A large amount of techniques have been proposed to identify whether a multimedia content has been illegally tampered or not. Nevertheless, very few efforts have been devoted to identifying which kind of attack has been carried out, especially due to the large data required for this task. We propose a novel hashing scheme which exploits the paradigms of compressive sensing and distributed source coding to generate a compact hash signature, and we apply it to the case of audio content protection. At the content user side, the hash is decoded using distributed source coding tools. If the tampering is sparsifiable or compressible in some orthonormal basis or redundant dictionary, it is possible to identify the time-frequency position of the attack, with a hash size as small as 200 bits/second; the bit saving obtained by introducing distributed source coding ranges between 20% to 70%. The audio content provider produces a small hash signature by computing a limited number of random projections of a perceptual, time-frequency representation of the original audio stream; the audio hash is given by the syndrome bits of an LDPC code applied to the projections. By using the DCT as signal preprocessor in order to obtain a sparse representation in the frequency domain, we show that the subsequent application of CS represent our signals with less information than the well-known sampling theorem. This means that our results could be the basis for a new compression method for audio and speech signals.Key words: digital audio data authentication, robust audio fingerprinting system, Multimedia Signal Processing Reference [1] M Steinebach, J Dittmann, Watermarking-based digital audio data authentication.

The Santa Catarina Mark 1 Bioimpedance System: Preliminary ResultsAbstract: The electrical bioimpedance spectroscopy is used as powerful technique for characterizing biological materials and detecting tissue anomalies. Commercial impedance analyzers can make impedance measurements of biological materials in a wide frequency range. However, they are expensive and have not been manufactured for measuring in vivo biological materials due to safety concerns. This work presents the performance of first bioimpedance system of the State University of Santa Catarina (BIATRON I). It is based on a FPGA which generates the signals and processes the data to be visualized in the computer via an USB interface. It contains an isolated front-end measuring system, guard electrodes for compensating cable capacitances and an impedance probe which can be fully sterilized in autoclaves. Measurements were taken from five saline solutions in order to perform the system frequency response. Data were converted into impedance by using a novel PSO algorithm. Results have shown that the developed system is reliable for measuring impedance spectra of saline solutions. Future measurements from biological tissues are going to be done for a fully characterization.Key words: Electrical Bioimpedance, FPGA, Guard Electrodes, PSO Algorithm, Tissue Impedance Reference [1] S.

| 383. | An Improved Variable Step-Size Incremental Lmsadaptive Algorithm over Distributed Networks for Dealing with Changing Noise
An Improved Variable Step-Size Incremental Lmsadaptive Algorithm over Distributed Networks for Dealing with Changing NoiseAbstract: In this paper we will study the performance of improved variable step-size LMS algorithm over distributed networks when dealing with jump systems and changing noise environments. In jump systems the energy and variance of noise changes suddenly and then gets back to normal afterwards. The conventional VSSLMS algorithm cannot keep pace with these variations, and the performance degrades dramatically. So we propose an improved adaptive variable stepsize LMS algorithm to mitigate these performance deficiencies over distributed networks that face with jumping and changing noise frequently.Key words: variable step-size, least mean square, jump noise systems, distributed networks, incremental.

Static pressure coefficients are calculated along the chord length for different angles of attack for both the test models and the results are compared. Further, the relationship between coefficient of drag and Reynolds number has been arrived for different angles of incidence. It was found that coefficient of drag decreases as the Reynolds number increases and cd is higher at higher angles of incidence for both the aerofoil and automobile dome.Key words: Wind Tunnel; Angle of Attack (AOA); Pressure Reference [1] Anderson Jr, J.D., Computational fluid dynamics: The Basics with Applications.Mc Graw-Hill, Inc, New York, 1995.

Image Thumbnails Using Reducing MethodAbstract: A standard image thumbnail is generated by filtering and sub sampling when the blur and noise of an original image is lost since the standard thumbnails do not distinguish between high quality and low quality originals. In this paper an efficient algorithm with a blur –generating component and a noise generating component preserves the local blur and the noise of the originals. The new thumbnails are more representative of their originals for blurry images .The noise generating component improves the results for noisy images but degrades the results for textured images .The decision to use the noise component of the new thumbnails should based on testing with the particular image mix expected for the application.Key words: Standard thumbnails, image quality, noise modeling Reference [1] A.K.Jain Fundamentals of Digital Image Processing.Englewood cliffs NJ; Prentice-Hall,1989.

ULTRA-LOW POWER SUBTHRESHOLD CMOS INVERTER AT 90nm CMOS TECHNOLOGYAbstract: In the medium power consumption design region, alot of efforts have been made. However, much research has not been done at the ultra-low power with acceptable performance and high performance design with power. This paper focuses on design techniques for ultra-low power dissipation where performance is of secondary importance. One way to achieve this goal is by running the CMOS inverter circuit in sub threshold mode.[2,3]The incentive of operating the circuit in sub threshold mode is to be able to exploit the sub threshold leakage current as the operating current for the circuit.Key words: Sub threshold Power, CMOS Inverter Reference [1] Srinivasa Rao.Ijjada, S.V.Sunil Kumar,M.

Context Based Dynamic Verbal Management SystemAbstract: Verbal ability refers to a person's facility at putting ideas into words, both oral and written. This facility involves possessing not only a strong working vocabulary but also the ability to choose the right words to convey nuances of meaning to a chosen audience. Verbal ability is usually demonstrated as the ability to write and speak well. We describe an approach to construct a learning tool that makes a complex text document to be simple without losing its context and meaning to user or the reader of the document. The word resource that will be using is WordNet which is an open source under Princeton University which is a outcome of 30years of research and dedication. This tool not only make the text to be simple but even this will make the tool to go dynamic by developing its knowledge base with the WordNet and things to go updated into synsets. In this paper we present the methodology for Word Sense Disambiguation based on domain information. Domain is a set of words in which there is a strong semantic relation among the words.Key words: WordNet, Comprehension Index (CI), Word Sense Disambiguation (WSD), Word Knowledge, Domain.

Imitated Rulepossession From Identical Web Sites Using Rule OntologyAbstract: The rule ontology is a generalized, condensed, and specifically rearranged version of the existing rules. Rule acquisition research is relatively unpopular while there are many works on ontology learning. We proposed an automatic rule acquisition procedure using ontology, named Rule To Onto, that includes information about the rule components and their structures. We started from the idea that it will be helpful to acquire rules from a site if we have similar rules acquired from other similar sites of the same domain. Rule To Onto is a generalized, condensed, and specifically rearranged version of the existing rules. The rule acquisition procedure consists of the rule component identification step and the rule composition step. We used stemming and semantic similarity in the former step and developed the A* algorithm[1] in the latter step. This paper focuses on using Rules Extraction to automatically augment web pages with semantic annotations, and find out whether and how ontology Rules Extractions could be used in the extraction process.Key words: rule extraction, rule onto, semantic similarity, stemming.

Designing Of a Low Cost Based Alerting System to Prevent the Train Accidents Using GSM and GPS TechnologyAbstract: This paper is proposed to design the rail engines with a new emergency automatic braking system called Vigilance Control Device (VCD) to prevent the train accidents due to the un-alertness of the loco pilots. The proposed system is a microcontroller based safety system which will enhance safety of the passengers by cyclically generating warnings and by automatically stopping the train if the driver is fast asleep or incapacitated or dead. This paper also gives the information to the higher authorities regarding the position of the loco crew and the position of the train where it is stopped by using Global System for Mobile communication (GSM) and Global Positioning System (GPS) technologies. If the loco pilot does not perform a regular task such as accelerating or braking for a stipulated period of time a message will be send to the Vigilance Control Officer (VCO) through GSM. After the train is stopped automatically by applying the penalty brake, its position is tracked by GPS and a message will be send to the vigilance control officer.Key words: Control, loco, GPS, GSM, pilot, vigilance Reference [1] ITSR, Driver Safety Systems Discussion Paper, 2006, Australia/New South Wales Independent Transport Safety Regulator: Sydney, p.32.

Ofdm Implementation Using Self-Cancellation Techniques in Wireless NetworksAbstract: With the rapid growth of digital communication in recent years, the need for high speed data transmission is increased. Moreover, futureWirelessSystemsare expected to support a wide range of services which includes video, data and voice. OFDMis a promising candidate for achieving high data rates in mobile environment because of its multicarrier modulation technique and ability to convert a frequency selective fading channel into severalnearly flat fading channels. Now OFDM is being widely used in wireless communications standards, such as IEEE 802.11a, the multimedia mobile access communication (MMAC), and the HIPERLAN/2. However, one of the main disadvantages of OFDM is its sensitivity against carrier frequency offset and high PAPR which causes intercarrier interference (ICI). This paper deals with design of an OFDM mechanism in a wireless technology and implementation of double frequency hopping in CDMA to overcome inter channel interferences.Key words: FHCDMA, HIPERLAN, ICI, MMAC, OFDM Reference [1] H.Sari,G.Karam,and I.

Enhanced High Resolution Colour Image Using Discrete and Stationary Wavelet TransformAbstract: The resolution of an image can be enhanced using a technique based on interpolation of the high frequency subband images obtained by discrete wavelet transform (DWT) and the input image. The edges are enhanced by introducing an intermediate stage by using stationary wavelet transform (SWT). DWT is applied in order to decompose an input image into different subbands. Then the high frequency subbands as well as the input image are interpolated. The estimated high frequency subbands are modified by using high frequency subband obtained through SWT. Then all these subbands are combined to generate a new high resolution image by using inverse DWT (IDWT). This white balance is to average the brightest and darkest pixels on the image. Gaussian filters are a class of linear smoothing filters with the pixels chosen according to the shape of a Gaussian function. The amount of smoothing performed by the filter will be the same in all directions.Key words: Discrete wavelet transform, Stationary wavelet transform, Image resolution enhancement, Interpolation techniques, subband images, white balance, Gaussian filter Reference [1] Hasan Demirel And Gholamreza Anbarjafari "Image Resolution Enhancement By Using Discrete And Stationary Wavelet Decomposition" IEEE Transactions On Image Processing Vol.20.No.5.May 2011.

Implementing Agricultural Applications Using Wireless Sensor Network and Securing Them Using Advanced Encryption StandardAbstract: A wireless sensor network (WSN) is a large number of sensor nodes distributed throughout large geographical area of interest. These sensors monitor various conditions by measuring different parameters like temperature, pressure, sound, light intensity, heat, movement, etc. The sensed data is routed to the sink node via intermediate sensor nodes. Thus we get accurate information about the parameters present in that area. Application design can be simplified by providing a set of programming primitives for sensor networks that abstract the details of low-level communication, data sharing, and collective operations. The focus on sensor networks for agriculture has a main topic of low power consumption and efficient implementation of hardware and software for various applications.Reference [1].

An Object Shape Completion Using the Shape Boltzmann MachineAbstract: An object shape plays a crucial role in many computer vision applications such as segmentation, object detection, inpainting and graphics. An object shape mainly depends upon local and global variables. Local variables on the shape such as smoothness and continuity can help provide correct segmentations where the object boundary is noisy, unclear or lost in shadow. Global variables on the shape such as ensuring the correct number of parts (legs, wheels, wings etc) can resolve ambiguities where background clutter looks similar to part of the object. In this paper, we present a new learning algorithm for Boltzmann machines that contain two layers of hidden units that we call a Shape Boltzmann Machine (ShapeBM) for the task of modeling foreground/background (binary) and parts-based (categorical) shape images. We show that the ShapeBM can generate more realistic and generalized samples and ability to do shape completion suggests applications in a computer graphic setting.Key words: Boltzmann Machine, Generalized, Generative, Realistic, Sampling.

Assessing the Technical and Economic Feasibility of a Stand-Alone PV System for Rural Electrification: A Case StudyAbstract: Harnessing the solar energy to power electric appliances starts by converting the energy coming from the sun to electricity. Photovoltaic is the direct conversion of the solar energy into electricity. Exploiting of solar energy for domestic use is one avenue where the energy emitted from the sun is converted into electricity to power most if not all the appliances available at our homes and residences. Building a photovoltaic system is the process of designing, selecting and calculating the ratings of the equipments employed in the system. This paper presents a study on a stand-alone photovoltaic (PV) system to provide the required electricity for a single residential household in India. The complete design of the suggested system is carried out, such that the site radiation data and the electrical load data of a typical household in the considered site are taken into account during the design steps. Also, the life cycle cost (LCC) analysis is conducted to assess the economic viability of the system. The results of the study encouraged the use of the PV systems to electrify the rural sites in India.Key words: Renewable Energy Systems, Photovoltaic Stand-Alone Power System, PV array, storage battery.

Influence of Observed Clay Content on Shear Strength and Compressibility of Residual Sandy SoilsAbstract: The occurrence and distribution of soils in nature is such that, the various type of soil can be found together. Most of the engineering design methods and parameters of structures on soil have been developed for ideal soils such as pure sands or pure clays; the reality is that these ideal soils are rarely found in nature. In a sand-clay mixture, it is quite difficult to establish the characteristics of the soil since it possesses both the properties of sand and clay. Typical soils encountered in the Voltaian geological formation of Ghana is sand, however, particle size distribution of the Voltaian soils show that the sand occurs with other soil types especially clay. The influence of the clay portion of the soil on the strength and compressibility of the sandy soil has been investigated using field samples of sand and clay mixtures. It was established that, the soils cohesion increase with increasing clay content, the friction angle decreased with increasing clay content at the same moisture content. The compression index increases with the clay content and decreases with the initial void ratio. The plasticity index also increases with clay content.Reference [1] Dickson, K.B. and Benneh, G., A New Geography of Ghana. Pearson Educational Limited, Essex, England. 1988. [2] Kesse, G.

Traffic Generator Based Power Analysis of Different Routing Protocol For Mobile Nodes in Wireless Sensor Network Using QualnetAbstract: A sensor network is a system that consists of thousands of very small stations called sensor nodes. The communication between nodes is done in a wireless approach, and thus, the name of wireless sensor networks. The service lifetime of such sensor nodes depends on the power supply and the energy consumption, which is typically dominated by the communication subsystem. There has been growing interest in the WSN applications where traffic and mobility is the fundamental characteristic of the sensor nodes. The most important advantage of this traffic generator model is that it can be applied to all one and two dimensional traffic scenarios where the traffic load may fluctuate due to sensor activities.Key words: Wireless sensor network, Power model, Mobility, QualNet Simulator 5.0, Routing Protocols Reference [1] M.

Modern communication required an efficient spectrum usage and capacity and throughput.MC-CDMA provided the solution of these problems. MIMO refers to links with multiple antennas at the transmitter and receiver side. CDMA systems combined with multiple antennas is a promising technique, beyond 3G and 4G wireless communications. MIMO provides spatial diversity, which mitigates the fading. The usage of multiple antennas can significantly improve the performance of wireless communication system.

Synchronization of Signalised Intersections: A Case Study of Three Major Intersections on the 24th February Road, Kumasi, GhanaAbstract: Signalized intersections are critical elements of an urban road transportation system and maintaining these control systems at their optimal performance for different demand conditions has been the primary concern of the traffic engineers. Traffic simulation models have been widely used in both transportation operations and traffic analyses because simulation is safer, less expensive, and faster than field implementation and testing. This study evaluated performance of selected signalized intersections using micro simulation models in Synchro/SimTraffic. Traffic, geometric and signal control data including key parameters with the greatest impact on the calibration process were collected on the field. At 5% significant level, the Chi square test and t-test analyses revealed that headway had a strong correlation with saturation flow compared to speed for both field and simulated conditions. It was concluded that changes in phasing plan with geometric improvement would improve upon the selected signalized intersection's level of service. An interchange therefore should be constructed at Anloga intersection to allow free movement of vehicles thereby minimizing congestion and accident occurrences. Stadium and Amakom signalized intersections should be coordinated to allow as many vehicles as possible to traverse those intersections without any delay.Key words: Performance measures, Sensitivity Analysis, Signalized intersections, Synchro/ Sim Traffic, S Reference 1].

Development of FPGA for Custom Waveform Generator Based on Direct Digital SynthesizerAbstract: In this paper an efficient approach is present to design custom waveform generator based on DDS with low phase noise and high switching speed for military communication applications. It can generate custom signals with different modulations whose amplitude, frequency or phase are controlled by the description words given from an external computer. DDS is a frequency synthesizer which can generate arbitrary waveforms from a single, fixed frequency reference clock. In order to implement such custom waveform generator along with DDS we need FPGA. FPGA are used to realize DDS to meet different demand of the user such as high switching speeds. Then, the AD9858 used as the DDS core with compression ROM is compiled using Xilinx XC2V250 FPGA by VHDL language. The performances such as integration, expansibility are very much improved. We need design a Graphical User Interface (GUI), which allows simple control of the hardware.Key words: DDFS, FPGA, GUI, PIC, AD9858 Reference [1]. James A.

Automatic generation control of a two unequal area thermal power system with PID controller using Differential Evolution AlgorithmAbstract: The early aim of automatic generation control is to regulate the power output of the electrical generator with in a prescribed area in response to changes in system frequency, tie line loading, so as to maintain the scheduled system frequency and interchange with the other areas with predetermined limits. Automatic generation control of a multi-area power system provides power demand signals for its power generators to control frequency and tie line power flow due to the large load changes or other disturbances. Occurrence of large megawatt imbalance causes large frequency deviations from its nominal value which may result instability in the power system. To avoid such situation emerging control to maintain the system frequency using differential evolution based proportional integral-derivative (PID) controller has been used in this paper. Differential evolution (DE) is one of the most power full stochastic real parameter optimization in current use. Differential evolution based optimization gains give better optimal transient response of frequency and tie line power changes compared toLozi-map based chaotic algorithm (LCOA).Key words: DE: Differential Algorithm, AGC: Automatic Generation Control, ACE: Area Control Error, SLP: Step Load Perturbation,LFC: Load Frequency Control, Reference [1] O.I.

Monte Carlo Calculation of Electron Transport in GaAs and GaSbAbstract: Electron transport properties in GaSb and GaAs are calculated for different temperature, doping dependencies at high electric field applications. The calculations are performed using a three valleys ensemble Monte Carlo model that includes numerical formulations of the phonon scattering rates and ionized impurity scattering rates. For two materials, we find that electron velocity overshoot only occurs when the electric field in increased to a value above a certain critical field .This critical field is strongly dependent on the material parameters. Results from the two materials are finally compared. The agreement with the available experimental data is found to be satisfactory.Key words: Monte Carlo method; ionized impurity scattering; overshoot velocity Reference [1] G. W. Turner, S. J.

Grid Interconnection of RES for Power Quality Improvement by Using Fuzzy Logic ControllerAbstract: With the increase in load demand, the Renewable Energy Sources (RES) are increasingly connected in the distribution systems which utilizes power electronic Converters/Inverters. This paper presents a novel control strategy for achieving maximum benefits from these grid-interfacing inverters when installed in 3-phase 4-wire distribution systems. The use of non-linear loads in the power system will lead to the generation of current harmonics which in turn deteriorates the power quality. Active Power Filters (APF) are extensively used to compensate the current harmonics and load unbalance. The inverter is controlled to perform as a multi-function device by incorporating active power filter functionality.Key words: Active power filter (APF), distributed generation (DG), distribution system, fuzzy controller, power quality (PQ), Renewable energy sources (RES).

Content Based Image Retrieval Using Region Based Shape Descriptor and SVM AlgorithmAbstract: Content Based Image Retrieval (CBIR) system using Region based shape descriptors is proposed in my work. Further, the image classification efficiency is improved by employing Support Vector Machine (SVM) classifier. In this paper we concentrate on region based shape descriptors. In Region based shape descriptors include Hu moments, Zernike Moments, and exact Legendre Moment. In CBIR system the region based shape descriptors, viz., MI, ZM and ELM in terms of retrieval efficiency and retrieval time are observed.

For all materials, we find that electron velocity overshoot only occurs when the electric field in increased to a value above a certain critical field .This critical field is strongly dependent on the material parameters. Transient velocity overshoot has also been simulated, with the sudden application of fields up to1000 kV/m , appropriate to the gate-drain fields expected within an operational field effect transistor. The electron drift velocity relaxes to the saturation value of 105 m/s within 3 ps, for all crystal structures The steady state and transient velocity overshoot characteristics are in fair agreement with other recent calculations.Key words: Ensemble Monte Carlo, transient, Overshoot, drift velocity Reference [1] N.
