A Criss-Cross Metamaterial Based Electrically Small AntennaAbstract: Metamaterials (MM) have been able to make their position strong in the world of electromagnetic in the past years. Researchers have come up with several novel shapes which behave as metamaterials. The characteristic parameters of permittivity ε and the permeability μ were extracted by doing several experimentations and found them to be negative. This paper presents such a new shape namely Criss-Cross whose negative behaviour has been discussed. The mathematical modelling for finding the transmission and reflection coefficient of the wave in such medium has also been derived. Further, it has been used to reduce the size of a rectangular patch antenna.Key words: Metamaterial, negative index, permeability, permittivity, Jerusalem Cross. Reference [1] A.

Energy Planning Policies With Environmental Considerations In Nigeria
Energy Planning Policies With Environmental Considerations In NigeriaAbstract: The last decade has witnessed a fundamental change in the planning process for development in Nigeria. It is now recognized that the dimension of environment protection is of vital importance for sustainable development. From the comparative survey of available energy planning models, it was found that the environmental considerations are limited only to estimating the pollution load, thus sending false price signals to the technology market and leading to environmentally distorted policy decisions. The main focus of this research is a methodology for integrated energy sector planning, policy impact assessment, and policy mix analysis, incorporating the impact of environmental externality cost of energy supply and use into the planning process. The model aims at determining the least cost energy planning policy path for Nigeria with the least environmental damage.Key words: Energy Policy, Externality, Nigeria Reference [1]. Choppa, K.

| 4. | Optical Fibres in the Modeling of Translucent Concrete Blocks
Optical Fibres in the Modeling of Translucent Concrete BlocksAbstract: Translucent concrete is a concrete based material with light-transmissive properties, obtained due to embedded light optical elements like Optical fibers in it. Light is conducted through the stone from one end to the other. This results into a certain light pattern on the other surface, depending on the fibre structure. Optical fibres transmit light so effectively that there is virtually no loss of light conducted through the fibres. Our paper deals with the modelling of such translucent or transparent concrete blocks and their usage and also the advantages it brings in the field of smart construction.Key words: Translucent concrete, optical fibre, energy saving, smart construction.

| 5. | An Algorithm For Interval Continuous –Time MIMO Systems Reduction Using Least Squares Method
An Algorithm For Interval Continuous –Time MIMO Systems Reduction Using Least Squares MethodAbstract: A new algorithm for the reduction of Large Scale Linear MIMO (Multi Input Multi Output) Interval systems is proposed in this paper. The proposed method combines the Least squares methods shifting about a point 'a' together with the Moment matching technique. The denominator of the reduced interval model is found by Least squares methods shifting about a point 'a' while the numerator of the reduced interval model is obtained by Moment matching Technique. The reduced order interval MIMO models retain the steady-state value and stability of the original interval MIMO system. The algorithm is illustrated by a numerical example.Key words: Least Squares Mean, Large scale Interval system, order reduction, MIMO Systems Reference [1] SHOJI,F.F., ABE,K., and TAKEDA,H.,: "Model reduction for a class of linear dynamic systems‟, J.Franklin Inst.,319, pp.549-558, 1985.

Design & Implementation Of An Algorithm For Proximity Estimation In Sensor NetworkAbstract: Sensor networks are often used to perform monitoring tasks, such as in animal or vehicle tracking and in surveillance of enemy forces in military applications. In this project we will be introduce the concept of proximity queries that allow us to report interesting events that are observed by nodes in the network that are within certain distance of each other. An event is triggered when a user programmable predicate is satisfied on a sensor node. To study the problem of computing proximity queries in sensor networks using existing communication protocols and then propose an efficient Algorithm that can process multiple proximity queries, involving several different event types. This project gives solution utilizes a distributed routing index, maintained by the nodes in the network that is dynamically updated as new observations are obtained by the nodes. This project presents an extensive experimental study to show the benefits of this techniques under different scenarios.Key words: —position estimation, wireless sensors network, decentralized algorithm, position-based routing, location identification Reference [1] Sanjiv Rao and V Vallikumari, Associate Professor, Dept of IT, Sri Sai Aditya Institute of Science And Technology, Surampalem, AP India.

| 7. | Optimization of Haematite Mass-Input for Minimum Remnant
Sulphur Content in Iron Ore Beneficiated with Powdered
Potassium Chlorate
Optimization of Haematite Mass-Input for Minimum Remnant Sulphur Content in Iron Ore Beneficiated with Powdered Potassium ChlorateAbstract: A model was derived for optimization of haematite mass-input during its beneficiation with powdered potassium chlorate in order to ensure a minimum remnant sulphur condition in the ore. The polynomial model; S=0.1233 2 -0.8042 +18.823 is rooted in the expression 5.3126 x 10-2 S=6.5505 x 10-3 2 - 0.0427 +1 where both sides of the expression are correspondingly approximately equal to 1. The maximum deviation of the model-predicted concentration of remnant sulphur (during the beneficiation process) from the concentrations obtained from regression model and experiment were less than 3 and 2% respectively. These translate to confidence levels of 97 and 98% respectively. The remnant sulphur content of the ore per unit massinput of iron oxide ore beneficiatedas obtained from experiment, derived model and regression model are 0.4920, 0.5520 and 0.5335 mg/kg g -1 respectively. The standard errors in predicting the remnant ore sulphur for each mass-input value of the iron oxide ore beneficiated (STEYX) is 0.3778 compared to experimental (0.4920) and regression model (2.805 x 10-5 ). The measure of variability (AVEDEV) in the results of concentrations of remnant ore sulphur from regression model, experimental and modelpredicted are 6.6625, 6.6625 and 6.6430% respectively. The F-test between the derived and regression model is 0.8234 and then 0.9814 between the derived and experimental results. Evaluations from experimental results and optimization of massinput of the iron oxide ore as well as predictions by derived model (D-Model) and regression model (RModel) indicate that a minimum remnant sulphur content of the ore ≈ 18 mg/kg would be achieved at an optimum ore mass-input of 3.2616g during the beneficiation process providing the mass-input of oxidant (KClO3) and treatment temperature remained constant.Key words: Model, Optimization, Haematite Massinput, Minimum Remnant Sulphur.

| 8. | Efficient Clocking System Using Sequential Elements With Low Power Consumption
Efficient Clocking System Using Sequential Elements With Low Power ConsumptionAbstract: Low power flip-flops which plays a vital role for the design of low-power digital systems. Flip flops and latches consume a large amount of power due to redundant transitions and clocking system. In addition, the energy consumed by low skew clock distribution network is steadily increasing and becoming a larger fraction of the chip power. Almost, 30% - 60% of total power dissipation in a system is due to flip flops and clock distribution network. In order to achieve a design that is both high performances while also being power efficient, careful attention must be paid to the design of flip flops and latches. We survey a set of flip flops designed for low power and High performance.Key words: Flip-flop, Low Power, Clocking system. Reference [1] C. L. Kim and S.

Software as a Service (SaaS) for Management information system using multiple tenantsAbstract: Today, reliable broadband internet access, service-oriented architectures (SOAs), and the cost inefficiencies of managing dedicated on-premises applications are driving a transition toward the delivery of decomposable, managed, shared, Web-based services called software as a service (SaaS). Tenants using a multitenant service operate in virtual isolation from one another; Organizations can use and customize an application as though they each have a separate instance, yet their data and customizations remain secure and insulated from the activity of all other tenants. The single application instance effectively morphs at runtime for any particular tenant at any given time. Multitenancy is an architectural approach that pays dividends to both application providers and users. Operating just one application instance for multiple organizations yields tremendous economy of scale for the provider. Only one set of hardware resources is necessary to meet the needs of all users, a relatively small, experienced administrative staff can efficiently manage only one stack of software and hardware, and developers can build and support a single code base on just one platform (operating system, database, etc.) rather than many. The economics afforded by multitenancy allow the application provider in turn offer the service at a lower cost to customers.Key words: Cloud Computing, Multitenancy, SaaS, Virtualized database.

Kiswahili Linux Localization: Will Kiswahili be used worldwide in the Information and Communication TechnologyAbstract: Any nation using its own language as the national language has to consider herself as a nation of self confidence and identity. Tanzania with a population of more than 40 million people is proud of using its natural language Kiswahili in the daily communications. However, Kiswahili is not present in the potential and promising sector of the new Information and Communication Technologies (ICT). This paper describes the relevance of Kiswahili as the national and regional language and the need for bringing Kiswahili into the Information and Communication Technologies sector. The paper presents an initiative to localize Open Source Software including such as open office, firefox browser, Linux and others to Kiswahili and a proposed methodology to accomplish this challenge.Key words: Kiswahili, ICT, Open Source Software, Localization Reference (1) M.M.Mulokozi, Kiswahili as a National Language, Institute of Asian and African Studies IAS), Finland 2002.

| 12. | An Innovative Strategy for Maintenance of Highway Pavement
An Innovative Strategy for Maintenance of Highway PavementAbstract: Highway pavement are deteriorating fast due to lack of timely maintenance, leading to higher vehicle operating costs, increasing number of accidents etc. Thus, timely maintenance of the highway pavement is essential. Because, once pavements start to deteriorate; they deteriorate rapidly beyond the point where maintenance is effective. Thus, there is an urgent need to develop a strategy for maintenance of pavement in a huge highway network. In this study, an innovative strategy for maintenance of highway pavement is proposed. A two stage maintenance strategy is proposed. In stage I, it is proposed to determine priority of highway sections. In Stage II, priority of various maintenance activities to be carried out on various sections will be determined. Maintenance priority of the pavement is based on importance of the road sections, present road conditions, and future road conditions. The methodology proposed in this study is illustrated with the help of example of some hypothetical highway network consisting of 4 sections. Analysis results indicated that the proposed strategy is considered to be more rational, innovative & logical. Some strategies for maintenance of urban roads are also presented in this study. Therefore, it is expected that this study will be useful for maintenance of huge highway network in India and thus will be useful for preserving huge asset of pavement infrastructureKey words: Highway Maintenance; Maintenance Strategy; Maintenance Priority; Maintenance of urban roads, Reference 1) Agarwal, P.K.,"Road Condition, Prioritization and optimal resource allocation for Highway Maintenance at Network Level", Ph.

Fair Contract Signing Protocol Based On Secret SharingAbstract: A fair contract signing protocol allows two potentially mistrusted parties to exchange their commitments to an agreed contract over the Internet in a fair way so that either each of them obtains the others signature or neither party does. The existing protocols face the problem of more number of transactions in between TTP and party. Also the time complexity and computational complexities are more. In this paper we are proposing a fair contract signing protocol based on secret sharing scheme. The proposed method satisfies property of abuse freeness and fairness. That is if the protocol is executed unsuccessfully, none of the two parties can show the validity of intermediate results to others. The proposed scheme is more reliable, secure and less complex .Key words: Contract signing, Secret Sharing, Visual Cryptography Reference [1] Abadi, N. Glew, B. Horne, and B.

TRANSPORTATION NETWORK ANALYSIS BY USING REMOTE SENSING AND GIS A REVIEWAbstract: With the advent technology of Remote Sensing (RS) and Geographic Information Systems (GIS), a network transportation (Road) analysis within this environment has now become a common practice in many application areas. But a main problem in the network transportation analysis is the less quality and insufficient maintenance policies. This is because of the lack of funds for infrastructure. This demand for information requires new approaches in which data related to transportation network can be identified, collected, stored, retrieved, managed, analyzed, communicated and presented, for the decision support system of the organization. The adoption of newly emerging technologies such as Geographic Information System (GIS) can help to improve the decision making process in this area for better use of the available limited funds.

Semantically Detecting Plagiarism for Research PapersAbstract: Plagiarism means copying of published work without proper acknowledgement of source. Plagiarism is a major concern, in an academic environment, which affects both the credibility of institutions as well as its ability to ensure quality of its student. Plagiarism detection of research papers deals with checking similarities with other research papers. Manual methods cannot be used for checking research papers, as the assigned reviewer may have inadequate knowledge in the research disciplines. They may have different subjective views, causing possible misinterpretations. Therefore, there was an urgent need for an effective and feasible approach to check the submitted research papers with support of automated software. A method like- text mining method came into picture to solve the problem of automatically checking the research papers semantically. Our proposed system uses Term Frequency- Inverse Document Frequency (TFIDF) and Latent Semantic Indexing (LSI) to semantically find plagiarism.Key words: Decision Support Systems, Latent Semantic Indexing (LSI), Term Frequency- Inverse Document Frequency (TF-IDF), Text Mining Reference [1] J.

Analysis and Modeling of Agricultural Land use using Remote Sensing and Geographic Information System: a ReviewAbstract: GIS, remote sensing and Global positioning System are the most widely useful tools for land use planning and decision support system. Remotely sensed imagery is beneficial for agricultural production. It gives the accurate information of agricultural activities such as different crop identification and classification, crop condition monitoring, crop growth, crop area and yield estimation, mapping of soil characteristics and precision farming. Information from remotely sensed imagery, geographic information system and global positioning system allows farmers to carry only affected areas of a field. Problems within the field may be identified before they create a big problem in the agricultural production using remotely sensed images. This paper attempts to review different techniques for various applications of GIS and Remote sensing for land use/land cover change detection, crop identification and classification, crop condition monitoring, crop growth, crop area and yield estimation, mapping of soil characteristics and precision farming. Thus implementating GIS and RS for better production of the crops as well as land use/land cover change detection can be achieved.Key words: Classification, Crop acreage and yield estimation, Precision farming, RS and GIS, Soil mapping Reference [1] Meliadis Ioannis, Miltiadis Meliadis, Multi-temporal Landsat image classification and change analysis of land cover/use in the Prefecture of Thessaloiniki, Greece, Proceedings of the International Academy of Ecology and Environmental Sciences, 1(1): 15-25, 2011.

Autonomous Reconfiguration for Wireless Mesh NetworkAbstract: The demands for the network usage are increasing day by day. During their lifetime, multihop wireless mesh networks (WMNs) experience frequent link failures caused by channel interference, dynamic obstacles, and/or applications' bandwidth demands, which may degrade the system performance. This paper presents an autonomous network reconfiguration system (ANRS) that enables a multiradio WMN to autonomously recover from local link failures to preserve network performance. Using ANRS necessary changes are made in local and radio channel assignments for failure recovery. Next, based on the thusgenerated configuration changes, the system cooperatively reconfigures network settings among local mesh routers. ANRS has been implemented extensively on our IEEE 802.11- based WMN through ns2-based simulation. Our evaluation results show that ANRS outperforms existing failure-recovery schemes in improving channel-efficiency and in the ability of meeting the applications' bandwidth demands.Key words: -IEEE 802.11, multiradio wireless mesh networks (mr-WMNs), Routing, selfreconfigurable networks, wireless link failures.

A Computational Approach for Analyzing and Detecting Emotions in Arabic TextAbstract: The field of Affective Computing (AC) expects to narrow the communicative gap between the highly emotional human and the emotionally challenged computer by developing computational systems that recognize and respond to the affective states of the user. Affect-sensitive interfaces are being developed in number of domains, including gaming, mental health, and learning technologies. Emotions are part of human life. Recently, interest has been growing among researchers to find ways of detecting subjective information used in blogs and other online social media. This paper concerned with the automatic detection of emotions in Arabic text. This construction is based on a moderate sized Arabic emotion lexicon used to annotate Arabic children stories for the six basic emotions: Joy, Fear, Sadness, Anger, Disgust, and Surprise. Our approach achieves 65% accuracy for emotion detection in Arabic text.Key words: Emotion recognition, affective computing, human- machine interaction, emotional Arabic lexicon, text analysis.

Reduction Of Cod And Bod By Oxidation: A Cetp Case StudyAbstract: The present study is focused on a Common Effluent Treatment Plant (CETP) located at Umaraya, District Baroda. Waste water from about thirty five small and medium scale industries majorly comprising of chemical manufacturing and pharmaceutical industries are treated in this CETP. The incoming wastewater was collected and segregated into three groups as per their BOD/COD ratio. They were then oxidized independently by two oxidants Fenton's reagent (Fe2+/H2O2) and Sodium Hypochlorite (NaOCl) and reduction in COD and BOD were observed at different chlorine, H2O2, FeSO4 doses, different pH values and contact time for determining the optimum values. COD and BOD values at optimized conditions for the two oxidants were compared and observed that maximum reduction of 64.35% and 68.57% respectively was achieved by Fenton's reagent. The results clearly indicate that conventional system should be replaced by advanced oxidation process and Fenton's reagent is a suitable choice.Key words: CETP, COD and BOD reduction, Fenton's Reagent, Optimum Conditions, Oxidation Reference [1] Putri F.

Production of gasoline-like fuel obtained from waste lubrication oil and its physicochemical propertiesAbstract: In this study, our main focus is on finding alternative fuel resources and utilizing them to eliminate their negative effects. Because of the limitations of petroleum products, the used engine oils can be used in engine as engine oil after purifying it. Production of gasoline like fuel from used engine oil is involving chemical filtrations and blending process. The GLF is produced from waste engine lubrication oil (WLO) using the pyrolitic distillation method. Firstly, the WLO collected in a tank was particulates removed by a refining process. The refined lubrication oil samples were taken into a reactor and blended with some catalysts, and purified from dust, heavy carbon soot, metal particles, gum-type materials and other impurities. A fuel production system mainly consisting of a seven main parts using are waste oil storage tank, filters, a reactor, oil pump, a product storage tank, thermostats and control panel. The characteristic such as density, viscosity, flash point, heating value, sulphur content and distillation of the GLF are deliberated. The gasoline like fuel can be used in gasoline engine without any problem and increases the engine performance.Key words: Waste oil; Gasoline fuel; Gasoline engine; properties; pyrolitic distillation method; Engine performance Reference [1] Phan AN, Phan TM.

Performance Evaluation Of Some Algorithms For Acoustic Images Using Image Segmentation TechniqesAbstract: This paper is concerned with Unsupervised sonar image segmentation .We present a new estimation and segmentation procedure on images provided by a high resolution sonar. The sonar image is segmented in to two kinds of regions:Shadow (corresponding to a lack of acoustic reverberation behind each object lying on seabed) and Reverberation (Due the reflection of acoustic wave on the seabed and on the objects).The unsupervised contextual method is defined as a two-step processExpectation Maximization Algorithm and Statistical Region SnakeTheory[1]. The expectation maximization algorithm is very useful for parameter estimation problems in finite mixtures. The stochastic EM algorithm is a widely applicable approach for computing maximum likelihood estimates for the mixture problem[2].During past years the active contour models (Snakes) have been widely used for finding the contours of objects. This segmentation strategy is classically edge-based in the sense that the snake is driven to fit the maximum of an edge map of the scene.This technique has been successfully applied to real sonar images, and is compatible with an automatic processing of massive amounts of dataKey words: Active contours , Image edge detection , Imageprocessing ,Unsupervised Imagese gmentation ,Expectation,MaximizationAlgorithm, Snake Algorithm , Reference [1] R.

A Simplified Topology for Seven Level Modified Multilevel Inverter with Reduced Switch Count TechniqueAbstract: In this paper, a seven level modified cascaded multilevel inverter is proposed for industrial drive applications. Apart from selecting the conventional level inverters, Multi level inverters has been chosen for the industrial drive applications as it reduces the total harmonic distortion. The involvement of higher number of switches increases the complexity of the system, which leads to losses in switching, producing huge harmonics and in the end, it entirely reduces the efficiency of the system. The cascaded multilevel inverter involves only fewer switches, where it reduces the complexity of the system which in turn reduces the harmonics and reduces the complexity of the system and in total it reduces the total harmonics distortion.Key words: Cascaded Multilevel Inverter, Insulated Gate Bipolar Transistor, Pulse Width Modulation, Total Harmonic Distortion.

The Effect Of Rice Husk Ash Used As Supplementary Cementing Material On Strength Of MortarAbstract: This paper summarizes the experimental studies on strength characteristics of cement mortar in which rice husk ash (RHA) is used as partial replacement of ordinary Portland cement (OPC). Cement mortar paste were proportioned with varying dosages of RHA as partial replacement of OPC in the range of 5%to 30% by weight of cement. The compressive strength test was carried out as per relevant Indian standard code of practice. It has been observed that replacement of cement to the extent of approximately 10% by weight of cement was found to give the optimum results for the 28 days strength.Key words: Rice husk ash, mortar, pozzolanic material, strength.

| 26. | Experimental Investigation on Mechanical Properties of Flyash Concrete and Flyash Fiber Reinforced Concrete
Experimental Investigation on Mechanical Properties of Flyash Concrete and Flyash Fiber Reinforced ConcreteAbstract: The present Experimental investigation is to study the Mechanical Properties of the Fly ash concrete reinforced with steel fibers. The concrete composite comprises of steel fibers in different percentages and partial replacement of cement in different proportions. Steel fibers varied from 0%, 0.5%, 1% and 1.5% by weight of cement and replacement of fly ash varied from 0%, 10%, 20%, 30% and 40% by weight of cement. Specimens were tested for 28 days, 60 days and 90 days and behaviour of the flyash concrete, steel fiber reinforced concrete and fly ash concrete reinforced with steel fibers were studied. When the specimens were tested for 28 days strength, reduction in the Compressive strength, Split tensile strength and Flexural strength were observed, while the 90 days strength of the specimens were found to increase considerably. Based on the test results on control specimens, it was found that improvement in strength of concrete is achieved with a optimum steel fiber content of 1.5% and replacement of cement upto 30% by fly ash. The investigation programme included the determination of the optimum fiber content which can be provided in the concrete composites. Optimum fiber content was determined based on the Compressive strength, Split tensile strength, Flexural strength of the standard specimens. As the steel fiber percentage selected for our investigation is upto 1.5% by weight, it is suggested that this percentage may be increased to explore the possibility of using more steel fibers in fly ash concrete.Key words: Steel Fiber reinforced concrete, Flyash fiber reinforced concrete, Compressive strength, Split tensile strength, Flexural strength.

Physicochemical properties on Non Edible Crude Oil with Its Performance Analysis on Base Fuel (Diesel Fuel)Abstract: Biodiesel is a mixture of fatty acid alkyl esters obtained by the reaction of triglycerides of vegetable or animal origin with alcohol in the presence of a catalyst. In this work the biodiesel has been taken as non edible type in nature. The problems of this oil are attributed to high viscosity, low volatility and polyunsaturated character of vegetable oils. Hence, process of transesterification is found to be effective method of reducing viscosity and eliminating operational and durability problems. The comparative performance on the basis of physicochemical property of biodiesel and base fuel is also presented in this work. The advantages effect of biodiesel as compare of base fuel has been also shown.Key words: Biodiesel, No edible Oil, Transerterification, Diesel fuel (base fuel).

The mathematical modeling of beam element covered with LPA based on Timoshenko beam element theory and linear theory of piezoelectricity has been used. This work shows how number of actuators, actuator size, actuator location on beam and control voltage are depended on the desired shape of beam. Initial condition of beam is taken as horizontal position and three higher order polynomial curves are taken as desired shapes for beam to achieve. Here error between desired shape and achieved shape is taken as an objective to minimize, size, location and control voltage of actuators taken as variables.

Landmark based shortest path detection by using Dijkestra Algorithm and Haversine FormulaAbstract: — In 1900, less than 20 percent of the world population lived in cities, in 2007, just more than 50 percent of the world population lived in cities. In 2050, it has been predicted that more than 70 percent of the global population (about 6.4 billion people) will be city inhabitants. There is more pressure being placed on cities through this increase in population [1]. With advent of smart cities, information and communication technology is increasingly transforming the way city municipalities and city residents organize and operate in response to urban growth. In this paper, we create a generic scheme for navigating a route through out city. A requested route is provided by using combination of Dijkestra Algorithm and Haversine formula. Haversine Formula gives minimum distance between any two points on spherical body by using latitude and longitude. This minimum distance is then provided to Dijkestra algorithm to calculate minimum distance. The process for detecting the shortest path is mention in this paper.Key words: Haversine Formula, Dijkestra Algorithm, Google Map,XML Reference [1] By Mr. Reid "Shortest distance between two points on earth" http://wordpress.mrreid.org/haversineformula/ This is an electronic document.

Experimental Study of Base Isolation System for Small Equipments and Its EvaluationAbstract: A new device of reduction for seismic response using friction force was developed. In this paper, vibration analysis of a small base isolation system using the device was investigated by excitation experiment using artificial seismic waves. Peak acceleration amplitude on the base isolation system has decreased to 43 - 90% compared to input waves. And root mean square (RMS) amplitude has decreased to 76 - 94%. Although a spectral peak around 0.5 Hz that is equal to natural frequency of the system was identified when the input waves with low frequency band component were used, it was decreased using friction bearings that generate high friction force. Comparing the response waveforms of the excitation experiment and of the numerical analysis using a linear 2DOF model, it was good agreement. This system is useful for reduction of seismic response.Key words: - Seismic Response, Friction Bearing, Ball, Marble Plate, Natural Frequency, Damping Ratio Reference [1] M Ozaki, Y. Adachi, Y.

Classification of Multi-date, Tempo-Spectral data using NDVI valuesAbstract: NASA launched the Earth Observing System's flagship satellite "Terra," named for Earth, on December 18, 1999. Terra has been collecting data about Earth's changing climate Normalized Difference Vegetation Index (NDVI) is a simple graphical indicator that can be used to analyze remote sensing measurements. These indexes can be used to prediction of classes of Remote Sensing (RS) images. In this paper, we will classify the Terra image on NDVI values of 5 different date's images (Captured by Terra satellite). For classifying images, we will use formulae, which is based on similarity measure. It will compare the clustered image with the Reference image based on the equation, it will classify the image. It is simple process, which can classify much faster.Key words: -Terra, Normalized Difference Vegetation Index (NDVI), Remote Sensing, Multi date. Reference [1] A. Murni, A.K. Jain, and J.

Elimination of Harmonics of Induction Furnace by Appling PQ-Theory for the Control of Hybrid Selective Active FilterAbstract: This paper describes how to calculate the different harmonic sequences that should be filtered with a hybrid selective active filter, for two control alternatives: load current measurement or line current measurement. These results are then generalized for hybrid selective active filters. Passive parameters are chosen considering the resonances with the electric system that appear. Design basis are defined in order to obtain a minimum cost filter which also meet the applicable regulations requirements. In this paper presents a hybrid selective active filter configuration to mitigate harmonics, which uses shunt passive and active filters. To obtain the switching signals for the active filter have used instantaneous power theory proposed by H.Akagi. Hybrid selective active filter proposed scheme has been verified through various simulations in MATLAB-SIMULINK environment. Finally, results showing the potentiality of the selective filter controlled for the proposed methods are reported.Key words: Induction furnace, Hybrid selective active filter, pq –theory.

PLC Based Energy Management and Control Design for an Alternative Energy Power System with Improved Power QualityAbstract: This paper describes modeling and simulation of a renewable energy based hybrid power system in the aspects of improving power quality, energy management and control, because optimal utilization of primary energy sources will increase the level of supply reliability. In order to meet sustained load demands during varying natural conditions, different renewable energy sources and converters are need to be integrated with each other. The paper focuses on the combination of Photo Voltaic (PV) cell System, Wind turbine system, Fuel cell (FC), and Battery systems for power generation, and to improve power quality we are proposing MotorGenerator model instead of using static converters, and an energy management and control unit using Programmable Logic Controller (PLC). Since wind turbine output power varies with the wind speed, the PV cell output power varies with both the temperature and irradiance, and a FC output power varies with input fuel, and so, along with DC Motor, Diesel engine is also coupled to ensure that the overall system performs under all conditions, especially when PV, Wind, FC power is not enough to drive DC motor. Excess energy when available, is converted to hydrogen using an electrolyzer for later use in the fuel cell for the economic use of fuel. The results show that the proposed hybrid power system can effectively manage the optimal utilization of primary energy sources and improves the power quality in both islanding mode and as well as grid connected mode.Key words: —Hybrid Power system, Renewable energy Sources, DC Motor-Synchronous Generator set, Diesel engine, Islanding (Isolated) mode and grid connected mode, and Energy Management, PLCs.

Performance Analysis of AODV under Worm Hole Attack through Use of NS2 SimulatorAbstract: Wireless networks are gaining popularity to its peak from past, as the users want wireless connectivity irrespective of their geographic position. There is an increasing threat of attacks on the Mobile Ad-hoc Networks (MANET). Any node in mobile ad hoc networks operates not only as end terminal but both as an intermediate router and client. In this way, multi-hop communication occurs in MANETs and thus it is a difficult task to establish a secure path between source and destination. It generally works by broadcasting the information and used air as medium. Its broadcasting nature and transmission medium also help attacker, whose intention is to spy or disrupt the network. When two malicious nodes forward packet through a private "tunnel" in the network, in which one node is nearer to the source and other node is nearer to the destination and packet travelled through this malicious nodes. This type of activity is known as wormhole attack. NS2 is chosen as a simulation environment because it is one of the leading environments for network modeling and simulation.Key words: Mobile Ad hoc network,ns-2, Wormhole attack.

Numerical Modeling of the Groundwater Flow in Ennahud Basin, Northern Kordofan state - SudanAbstract: The groundwater model techniques were used to improve the understanding and evaluate the complex hydrogeological situation of the study area. Visual MODFLOW code was selected to run the model scenarios. The aquifer hydraulic conductivity, storativity, recharge, and constant head boundary (CHB) were adjusted during calibration to obtain acceptable match between calculated and observed heads and fluxes. The calibration of three-dimensional finite difference flow model of Ennuhud sedimentary aquifer was realized through the calibration which is acceptable within the average Root Mean Square error (RMS) of 1.482m, Residual Mean of 0.526m, and standard error of estimate to be 0.22 where the contour maps of the simulated heads produced by visual MODFLOW show fair similarity with those drawn using initial heads which confirm acceptable model calibration. The calculated zone budget reflects that volume of aquifer storage for the three years varies from 3.57 to 8.3 million cubic meters (mcm). The annual average pumpage was estimated through the model run to be 6.73 mcm, whereas, the annual historical pumpage was 6.2 mcm. The annual recharge was estimated to be; 143.8, 579.9 and 867.5 mcm during the three successive years (2005-2007) respectively, whereas the annual average recharge was 530.4 mcm. The model assigns the regional groundwater flow direction towards the center where some water flow diverges to localized cones of depression ascribed to heavy pumping. The contour maps of the simulated heads show fair similarity with those generated from initial heads which confirm acceptable model calibration. The predictive simulation for 10 years starting from 2005 shows that the continued pumping will create relatively high changes in head distribution in the model area, and gives a maximum drawdown of 5m at 2015.Key words: simulation, Trial- and- Error, zonebudget, aquifer, calibration Reference [1] Anderson, MP, and Woessner, WW, 1992.

Water Quality Index For Assessment Of Water Samples Of Different Zones In Chandrapur CityAbstract: The paper aims at determining the suitability of ground water of different zones in Chandrapur city with reference to index also termed as Water Quality Index (WQI). The objective of the index is to convert complex data pertaining to water quality into the most comprehensible and simple data that can be understood by general public and policy makers as a whole. The present work deals with monitoring of variation of seasonal WQI of selected locations of the city which is one of the most polluted city in the country as far as water and air pollutions are concerned. In the present study, groundwater sample of rainy and winter seasons of the selected different zones of the city were taken for investigation and analysed for various parameters with regard to drinking water standards and assessed for their suitability for human consumption.. After analysis it has been observed that ground water quality of most of the zones are not suitable for drinking water and deteriorates from rainy to winter season due to increase in microbial activity thereby highlighting the major issue of drinking water availability and measures to be adopted due to growing industrialization and unhealthy human activities.Key words: Ground water, Physico- Chemical characteristics, Pollution, Water Quality Index Reference 1) Report on Environment Action Plan of Chandrapur by Pollution Control Board 2) Indian standard drinking water, Specification (First Revision) IS- 10500:1991.

Mining and Predicting Users M-Commerce Patterns using Collaborative Filtering AlgorithAbstract: Mobile Commerce, also known as MCommerce or mCommerce, is the ability to conduct commerce using a mobile device. Research is done by Mining and Prediction of Mobile Users' Commerce Behaviors such as their movements and purchase transactions. The problem of PMCP-Mine algorithm has been overcome by the Collaborative Filtering Algorithm. The main objective is to analyse the Mobile users' movements to the new locations instead of considering only the frequent moving locations. In the existing approach, a Mobile Commerce Explorer Framework has been implemented to make recommendations for stores and items by analysing the Mobile users'. The drawbacks are the recommendations that made are only for frequently moving locations and stores. The proposed work is to recommend stores and items in new locations by considering the rating of items given by the other users in new locations.Key words: MMining, Prediction, Mobile Commerce Reference [1] Eric Hsueh-Chan Lu, Wang-Chien Lee, and Vincent S.

Comparison of Routing Protocol in MANETsAbstract: AOMDV is widely used protocol these days. But, its permissive for link failure. It takes the necessary action after detecting the link failure thus holding/queuing packets till new route is discovered after detecting failure in existing link.. Early Link Failure DetectionAOMDV (ELFDAOMDV) keeps on monitoring distance between two mobile nodes. As soon distance between two nodes crosses specified threshold then it sends a request to source node to start discovering new route but continues to transfer data packets as the link is still up. In most of the cases, new route is discovered (if some exists) before link failure. Then using the intelligence data packets are automatically shifted to this newly discovered route, thus preventing the link failure. Hence, the algorithm is named as Early Link Failure Detection - AOMDV.Key words: Ad hoc networks; Routing protocols; AODV, DSR, AOMDV.

Multiple Web Database Handle Using CTVS Method and Record MatchingAbstract: Web databases generate query result pages based on a user's query. For many applications, automatically extracting the data from these query result pages is very important, such as data integration, which needs to cooperate with multiple web databases. We present a novel data extraction and alignment method called CTVS that combines both tag and value similarity. CTVS automatically extracts data from query result pages by first identifying and segmenting the query result records (QRRs) in the query result pages and then aligning the segmented QRRs into a table, in which the data values from the same attribute are put into the same column. We present an unsupervised, online record matching method, UDD, which, for a given query, can effectively identify duplicates from the query result records of multiple Web databases. We propose new techniques to handle the case when the QRRs are not contiguous, which may be due to the presence of auxiliary information, such as a comment, recommendation or advertisement, and for handling any nested structure that may exist in the QRRs.Key words: Data extraction, automatic wrapper generation, data record alignment, information integration, Record matching, duplicate detection, record linkage.

Quaternary Adder Design Using VHDLAbstract: The high speed digital circuits became more prominent with incorporating information processing and computing. Arithmetic circuits play a very critical role in both general-purpose and application specific computational circuits. The modern computers lead to the deterioration in performance of arithmetic operations such as addition, subtraction, multiplication, division, on the aspects of carry propagation delay, large circuit complexity and high power consumption. Designing this adder using QSD number representation allows fast addition/subtraction which is capable of carry free addition and borrows free subtraction because the carry propagation chain are eliminated, hence it reduce the propagation time in comparison with radix 2 system. QSD number system based on quaternary system, each digit can be represented by a number from -3 to -3. Operation on large number of digits such as 64, 128 or more, can be implemented with constant delay and complexityKey words: v Reference [1] Nagamani A.

| 48. | A Survey On Seeds Affinity Propagation
A Survey On Seeds Affinity PropagationAbstract: Affinity propagation (AP) is a clustering method that can find data centers or clusters by sending messages between pairs of data points. Seed Affinity Propagation is a novel semisupervised text clustering algorithm which is based on AP. AP algorithm couldn't cope up with part known data direct. Therefore, focusing on this issue a semi-supervised scheme called incremental affinity propagation clustering is present in the paper where pre-known information is represented by adjusting similarity matrix The standard affinity propagation clustering algorithm also suffers from a limitation that it is hard to know the value of the parameter "preference" which can yield an optimal clustering solution. This limitation can be overcome by a method named, adaptive affinity propagation. The method first finds out the range of "preference", then searches the space of "preference" to find a good value which can optimize the clustering result.Key words: Affinity propagation, Clustering, Incremental, Partition adaptive affinity propagation and Text clustering Reference [1] S.

FPGA Implementation of cache memoryAbstract: We describe cache memory design suitable for use in FPGA-based cache controller and processor. Cache systems are on-chip memory element used to store data. Cache serves as a buffer between a CPU and its main memory. Cache memory is used to synchronize the data transfer rate between CPU and main memory. As cache memory closer to the micro processor, it is faster than the RAM and main memory.The advantage of storing data on cache, as compared to RAM, is that it has faster retrieval times, but it has disadvantage of on-chip energy consumption. In term of detecting miss rate in cache memory and less power consumption, The efficient cache memory will proposed by this research work, by implementation of cache memory on FPGA. We believe that our implementation achieves low complexity and low energy consumption in terms of FPGA resource usage.Key words: cache Tag memory, cache controller, counter, cache Tag comparator.

Determination of SOX Concentration in Ambient Air and its Dependency on Meteorological Parameters: A Case StudyAbstract: Present study have been conducted with the objectives of studying the impact of Meteorological parameters on Sox concentration in the campus of Hindustan College of Science and Technology, Farah Mathura. SOx concentration in the study area were determined experimentally for the period from February 2010 to April 2010. Meteorological parameters on Sox concentration the hourly meteorological parameters such as wind speed and direction, temperature, humidity and rainfall were also recorded by automated weather station installed at study site. Air samples were collected as per guidelines of Central Pollution Control Board norms at 24 hours intervals for two days in a week for four consecutive weeks in a month for three months (February, March and April, 2010). 24 Hrs average Sox concentrations determined biweekly on the basis of this experiment indicate that concentrations are higher in winter i.e. in February when temperature were low where as concentration decreases from March onwards when temperature began to rise. However concentration were below the National Ambient Air Quality Standards of Central Pollution Control Board, India i.e. 80µg/m3 for residential and rural area for all the duration of the study. Correlation between 24 Hours average SOX concentration and average daily values of wind speed, temperature and relative humidity were found to be very poor. However the correlation between 24Hrs average Sox concentration and instantaneous values of temperatures at 0.0 Hrs, 18.0 Hrs, 21.0 Hrs and 3.0 Hrs were found to be excellent. Regression equations were derived to predict the 24 Hrs Sox concentration in the study area based on the variables having excellent correlation with Sox concentration. These equations can be used to predict the Sox concentration in the study area when the experiment to determine the SOX concentration is not possible and hourly meteorological parameters are available.Key words: Sulphur Dioxide; air pollution; Wind Speed, Temperature, Humidity Reference [1].

Image and Pixel matching algorithm are required for implementing the Video Surveillance System. This is especially required for computer security applications, where our algorithms are effectively used. These algorithms are useful for tracking an object in motion and classifying it on the bases of motion level, which would help in subsequent motion detection analysis. So that when an activity occurs in absence of user, the application detects it and performs the required action. This algorithm helps to represent graphically the amount of changes occurred in the environment.Key words: Cluster Matching, Image Comparisons, Pixel Comparisons, Pixel level Estimation, Similarity Threshold, and Sub-pixel level Estimation.

Motion Detection and Target Tracking using Neural Network Correlation Co-efficient TechniqueAbstract: For an effective human computer intelligent interaction, the computer needs to recognize the motion and track the moving objects. Moving object detection is a crucial aspect of computer vision and video processing areas. Its basic operation involves the selection of significant segments of a video signal. Such operation is also called Target Tracking (the process of locating a moving object throughout a sequence of consecutive frames). The detection of moving objects in complex environments with various types of motion is a challenging problem because the camera motion and the object motion both are mixed. The process of moving object detection based on the background extraction is divided into two steps, background extraction and moving object detection. The basic idea is to capture a series of video pictures of the scene at regular intervals, the selected picture is divided into m*m blocks whose expectation and variance are calculated respectively to describe the vector information of the region. This paper proposes correlation co-efficient methodology to accomplish the process of motion detection and target tracking.Key words: Correlation Network, Motion Detection, Background Extraction, Target Tracking, Neural Network Reference [1] Moving object detection under free moving Camera by Jiman Kim, Guensu Ye, and Daijin Kim in Proceedings of 2010 IEEE 17th International Conference on Image Processing September 26-29, 2010, Hong Kong.

Design and Implementation of a Microcontroller Based PWM Sinewave Inverter for PV ApplicationsAbstract: A major factor worthy of consideration in the overall performance of any PV system is how the installed system can exploit the sun's energy most effectively by ensuring that arrays have full access to most of the solar resource. This research was therefore concerned with the modification of inverters to enhance the period for which energy is extracted from a PV system and to extend the range of voltages from PV that could operate inverters. To achieve this, the output of a 12V PV system was boosted to 24V then regulated back to 12V before inversion. A Microcontroller-based Pulse Width Modulated (PWM) Power Inverter for PV systems, suitable for use at homes as alternative power source for AC loads was designed, simulated and constructed. The most important feature of this system is that it is suitable for PV systems and highly effective in driving variable loads. Other features include provision for sensing the load voltage to adjust the pulse width to meet the load demand at every instance. It also provides the user with shutdown option in case of the system being idle (on no-load), the system can be put to standby mode instead of switching off the entire device. When on standby mode it consumes very small current of few milliamperes. The system was built around ATMELTM version of 8051 microcontroller AT89C2051.When tested the system was found to provide a constant sinusoidal voltage of 240V even with a varying voltages at the input.Reference [1].

The DRA is intended to be used as the radiating element of a transmitting array of active integrated antennas; its input impedance must exhibit a proper resistive load at the fundamental resonance frequency, as well as a dominant reactive behavior, either inductive or capacitive, at higher harmonics. The design procedure is performed by exploiting Artificial Neural Networks (ANN), to find the resonator geometry starting from the desired resonance frequency, and a finite element based numerical tool for the electromagnetic characterization of the antenna. The ANN can be employed in a designed RDRA over a short range of frequency of 5.68-5.9 GHz. After simulation this network can give a broad acceptance of simulated data of input and output dimensions of DRA with the possible original existence of the corresponding dimensions.Key words: Artificial Neural Network, Dielectric Resonator Antenna (DRA), Far Field, Gain, Bandwidth.

An Improved Electronic Load Controller for Isolated Small Hydro Wind Hybrid systemAbstract: A standalone hydro wind hybrid grid feeding a common three phase four wire load is considered. There are three generators Synchronous and Induction Generator fed by a hydro-turbine and a variable Wind speed turbine driven Permanent Magnet Synchronous Generator (PMSG). An Electronic Load Controller (ELC) based on Statcom principle is connected in shunt with the system. Vector control scheme for reference current generation technique of Statcom is developed. The major objectives in a standalone system are regulation of frequency and voltage. A battery bank is used on the dc side of Statcom thus enabling it for active power control and thus regulating the frequency. The ELC also performs other functions such as voltage regulation, reactive power compensation, neutral current compensation and harmonic elimination. The output from PMSG is connected to dc link via three phase voltage source converter (VSC) which is used for maximum power point tracking (MPPT). All models are developed using Matlab, Simulink.Key words: -Battery Energy Storage, Voltage and Frequency regulator, MPPT, Standalone Hydro Wind system Reference [1] I. Tamrakar, L.B. Shilpakar, B.G.

Optimization of cutting parameters in CNC TurningAbstract: Many manufacturing industries involve machining operations. In metal cutting the turning process is one of the most fundamental cutting processes used. Surface finish and dimensional tolerance, are used to determine and evaluate the quality of a product, and are major quality attributes of a turned product. In this paper experimental work has been carried out for the optimization of input parameters for the improvement of quality of the product of turning operation on CNC machine. Feed Rate, Spindle speed & depth of cut are taken as the input parameters and the dimensional tolerances as output parameter. In the present work L9 Array has been used in design of experiment for optimization of input parameters. This paper attempts to introduce and thus verifies experimentally as to how the Taguchi parameter design could be used in identifying the significant processing parameters and optimizing the surface roughness in the turning operation. The present work shows that spindle speed is the key factor for minimizing the dimensional variation for minimizing the surface roughness.Key words: Turning operation, Taguchi Method, Dimensional Tolerance.

Traffic based energy consumption analysis and improve the lifetime and performance of MAC protocols in ad hoc wireless sensor networksAbstract: Wireless microsensor networks lend themselves to trade-offs in energy and quality. The service lifetime of such sensor nodes depends on the power supply and energy consumption of nodes, which is usually dominated by the communication subsystem. One of the key challenges in unlocking the potential of such data gathering sensor networks is conserving energy so as to maximize their post deployment active lifetime. This paper described the research carried on the continual development of the novel energy efficient analysis of random placed nodes algorithm that increases the WSNs lifetime and improves on the QoS parameters yielding higher throughput, average end to end delay jitter for next generation of WSNs. Another key advantage of the novel analysis of random placed nodes algorithm is that it can be implemented with existing energy saving protocols like LEACH, SMAC and TMAC to further enhance the network lifetimes and improve on QoS parameters. The main aim of this paper is to improve energy in nodes and to analyze the most energy efficient MAC protocol in order to classify them and compare their performances. We are implemented some of WSN MAC protocol under QualNet 5.0 with the purpose to evaluate their performances.Key words: - MAC protocol, Energy consumption, Delivery ratio, Throughput, Delay Reference [1] T. van Dam and K.

Secure Routing in Wireless Sensor Networks using WEAP ProtocolAbstract: Wireless sensor networks are usually deployed for gathering data from unattended or hostile environment. Many sensor network routing protocols have been proposed, but they are very defenseless to security threats. Due to limitations of sensor devices, the networks are susceptible to hackers, it is possible for one to enter and render a network. In this paper we focus on a secure routing protocol called Wireless Extensible Authentication Protocol (WEAP). This protocol offers many security benefits to WSN's. Wireless EAP provides username/password-based authentication between a wireless client and a RADIUS server. WEAP only employs one base station and always assumes that it is trustworthy. This protocol tends to significantly reduce the attacks and increase the network performance.Key words: Wireless Sensor Network, WEAP protocol, Compromised nodes, Network protocols.

| 62. | μPCBComplexity
μPCBComplexityAbstract: System design complexity is increasing rapidly. As a result current development costs can be staggering and are constantly increasing. As designers produce ever larger and more complex systems, it is becoming increasingly difficult to estimate how much time it will take to design and verify these designs. To compound this problem, system design cost estimation still does not have a quantitative approach. Although designing a system is very resource consuming, there is little work invested in measuring, understanding, and estimating the effort required. To address part of the current shortcomings, this paper introduces µPCBComplexity, a methodology to measure and estimate PCB (printed circuit board) design effort. PCBs are the central component of any system and can require large amounts of resources to properly design and verify. µPCBComplexity consists of two main parts, a procedure to account for the contributions of the different elements in the design, which is coupled with a non-linear statistical regression of experimental measures. We use µPCBComplexity to evaluate a series of design effort estimators on several PCB designs. By using the proposed µPCBComplexity metric, designers can estimate PCB design effort.Reference [1] C.

Part-by-Part-Evaluation-on-Arrival approach involving modified eight point radix-2 FFT/IFFT for an OFDM transceiver to reduce latencyAbstract: An OFDM transceiver which will have the FFT/IFFT as an integral part will suffer latency due to the latter. This paper reduces the latency for a OFDM transceiver involving a 512 point FFT/IFFT function by using a modified 8 point radix2 FFT/IFFT. It performs Part-byPart-Evaluation-on-Arrival instead of evaluating FFT after the arrival of a full set of 512 input samples. This approach significantly reduces the latency in the OFDM transceiver and usage of a modified 8 point radix 2 FFT/IFFT as the basic unit to evaluate the large 512 point FFT/IFFT also reduces the computational requirements.

Seismic Response of Buildings with Column Reinforcement Lapped Just Above Floor LevelAbstract: The response of beam-column joints have long been recognized as a significant factor that affects the overall behavior of reinforced concrete (RC) framed structures subjected to large lateral loads. The reversal of forces in beam-column joints during earthquakes may cause distress and often failure, when not designed and detailed properly. The principle objective of this work is to analyze several "G+10" storey buildings having reinforcement joint (lap) just above the floors. An attempt is made to study the behavior of such structures with the conventional modeling. As a common practice, the structures are constructed by lapping the 100% of the reinforcement just above the floor instead of lapping it at mid height. It is assumed that column joints near the base where 100% lapping is being done, behaves as a hinge which will transfer only vertical/horizontal loads without moments. The response of such structure is compared with those where the detailing is done properly by maintaining the reinforcement joint at mid height and not more than 50% lapping is done.Key words: column joints, joints in RCC structures.

Collision Avoidance Mechanism In Wireless Ad Hoc Networks Through Distributed Mac ProtocolAbstract: -In this paper we are going to analyse Medium Access Control Protocols for high performance in Ad hoc Networks by increasing reliability in data transmission. In the mean while we can reduce collision among the nodes while transmitting information, by using collision avoidance Techniques. Medium access control (MAC) has been one of the important issues in wireless networks; CSMA/CA has been used in many high-speed and low-speed networks because of its robustness and simplicity. Performance of the medium degrades due to heavy collision among nodes and due to hiddennode problem.To achieve high-performance MAC is still an important issue in ad-hoc networks.Wireless networks are divided into onehop or multi hop networks. Depending on the number of wireless nodes over which a packet is relayed. Most of the existing networks are onehop, that is simple network and the complex network.Key words: MAC, CAIN, CSMA/CA, Complex network Reference [1] J. I. Chhoi, M. Jain, K.

Review of Various Intrusion Detection Techniques based on Data mining approachAbstract: Over the past several years, the Internet environment has become more complex and untrusted. Enterprise networked systems are inevitably exposed to the increasing threats posed by hackers as well as malicious users internal to a network. IDS technology is one of the important tools used now-a-days, to counter such threats. Various IDS techniques has been proposed, which identifies and alarms for such threats or attacks. IDS are an essential component of the network to be secured. The traditional IDS are unable to manage various newly arising attacks. To deal with these new problems of networks, data mining based IDS are opening new research avenues.. Data mining provides a wide range of techniques to classify these attacks. The paper provides a study on the various data mining based intrusion detection techniques.Reference [1] Mrs. Sneha Kumari, Dr. Maneesh Shrivastava "A Study Paper on IDS Attack Classification Using Various Data Mining Techniques" International Journal of Advanced Computer Research Volume-2 Number-3 Issue-5 September-2012.

Personal Identification Using Iris Recognition System, a ReviewAbstract: A biometric system provides automatic identification of an individual based on a unique feature or characteristic possessed by the individual. Unlike other biometric such as fingerprints and face recognition, the distinct aspect of iris comes from randomly distributed features. Iris recognition is regarded as the most reliable and accurate biometric identification system available. In this paper, I describe the novel techniques developed to create an Iris Recognition System available. This paper proposes a personal identification using iris recognition system with the help of six major steps i.e. image acquisition, localization, Isolation, normalization, feature extraction and matching and also these six steps consists a numbers of minor steps to complete each step. The boundaries of the iris, as papillary and limbic boundary, are detected by using Canny Edge Detector & Circular Hough Transformation. We can use masking technique to isolate the iris image form the given eye image, this isolated iris image is transformed from Cartesian to polar co-ordinate. Now finally extract the unique features (feature vector) of the iris after enhancing the iris image and then perform matching process on iris code using Hamming Distance for acceptance and rejectance process. Her I am giving my review after studying a number of research papers and my proposed technique works very well and can be easily implemented.Key words: Biometrics, Iris Code, Edge Detection, Transformation, Masking, Feature Vector, Hamming Distance.

| 76. | A Conjoint Analysis of the Design Irregularities and Public Realms of a National Highway in Bangalore
A Conjoint Analysis of the Design Irregularities and Public Realms of a National Highway in BangaloreAbstract: A 40m stretch along National Highway (NH4) is considered, which is located on either side of an unmanned exit from Yeswanthpur Railway station. This stretch of pedestrian walkway was extremely congested, with an average pedestrian count of about 4000/hour. This also led to pedestrian spillover and jaywalkers on the main carriageway. The absence of guardrails and the encroachment of footpath by street-hawkers aggravated the problem. Hence, the disruption of smooth pedestrian movement raises the accident rate and causes traffic delays. The width of the existing footpath is only 1.2m, while the ideal width should have been atleast 4m, as per standards. A high blank wall, demarcating the station and footpath, aggravated the persisting problem, by cutting the possible visual connection between them. This stimulated the abuse of the walkway by pedestrians. The dilapidated walkway and the unaltered footpath width continue to be a distress, with the level of service being 'F'. The remedial measures must incorporate proper design of walkways, ensuring transparency and fenestrations in the barricades, to establish a visual access between them, and thereby enhancing the urban public realm of 'seeing' and 'being seen'.Key words: Walkway, pedestrian, urban, jaywalkers, transparency.

| 77. | Different Techniques Of Edge Detection In Digital Image Processing
Different Techniques Of Edge Detection In Digital Image ProcessingAbstract: Edge detection is a process that detects the presence and location of edges constituted by sharp changes in intensity of an image. Edges define the boundaries between regions in an image, which helps with segmentation and object recognition. Edge detection of an image significantly reduces the amount of data and filters out useless information, while preserving the important structural properties in an image. The general method of edge detection is to study the changes of a single image pixel in an area, use the variation of the edge neighboring first order or second-order to detect the edge. In this paper after a brief introduction, overview of different edge detection techniques like differential operator method such as sobel operator,prewitt's technique,Canny technique and morphological edge detection technique are given.Reference [1].

Characterization of Al/(10%Al2O3-10%ZrO2)Nanocomposite Powders Fabricated by High-Energy Ball MillingAbstract: Al–10% Al2O3-10% ZrO2 nanocomposite powders were fabricated by high-energy milling of the blended component powders. Planetary Monomill "Pulverisette 6" was used in milling the powders for 45 hours at 300 rpm and a ball-topowder ratio of 10:1. A uniform distribution of the Al2O3 and ZrO2 reinforcements in the Al matrix was successfully obtained after powders milling process. This uniform distribution was confirmed by characterizing these nanocomposite powders by scanning electron microscopy (SEM). X-ray diffraction (XRD) patterns were recorded for the milled powders, and analyzed using Williamson–Hall method to determine the crystallite size and the lattice strain.

Mathematical Model of Sever and Coupler for Folded-Waveguide TWT at W-bandAbstract: A wideband folded waveguide travellingwave tube (TWT) amplifier has advantages of simple coupling structure and robust structure over conventional helix TWT. In millimeter wave bands sever are used to have good impedance matching especially in high-power tubes where efficiency is important. The common technique for suppressing the backward wave is through the use of one or more severs. In this paper mathematical model for a coupler and sever for the folded waveguide at W –band and numerical simulation is carried out using mat-lab.Key words: Folded-waveguide travelling-wave tube, couple, sever, Folded-waveguide slow wave structure.

Biodiesel production from neem oil using two step transesterificationAbstract: Currently, most of the biodiesel is produced from the edible/refined type oil using methanol and alkaline catalyst. However, large amount of non-edible type oils and fats are available in our country. In this study, crude neem oil is used as alternative fuel for biodiesel production. The difficulty with alkaline transesterification of these oils have contained large amounts of free fatty acids (FFA). These free fatty acids quickly react with the alkaline catalyst to produce soaps that inhibit the separation of the ester and glycerin. A two-step transesterification process is developed to convert the high FFA oils to its mono-esters. Using 100 ml of oil,the optimum combination of parameters for pretreatment were found to be .45 v/v methanol-oil-ratio,0.5%v/w H2SO4 acid catalyst, 50˚C and 45 min reaction time. After pretreatment of neem oil,transesterification reaction was carried out with 0.3:1 methanol-tooil ratio, 1%KOH as alkaline catalyst,1hr reaction time and 55˚C reaction temperature to produce the fatty acid methyl ester. This two step process gave maximum average yield of 90±2%.Key words: : Biodiesel, free fatty acid, Neem oil, pretreatment, transesterification. Reference [1 ] K.

SURVEY OF DIFFERENT DATA STRUCTURE BASED ASSOCIATION RULE MINING ALGORITHMSAbstract: Association rule mining is important data mining task for which many algorithms have been proposed. All these algorithms generally work in two phases, finding frequent itemsets and generating association rules from them. First phase is most time consuming in most of the algorithms because algorithm has to scan the database many times. Use of different data structures overcomes this drawback. In this paper we will survey the algorithms which make use of different data structures to improve association rule mining.Key words: Association rule mining, Data structures, Graph, Matrix, Tree.

| 85. | Survey of Combined Clustering Approaches
Survey of Combined Clustering ApproachesAbstract: Data clustering is one of the very important techniques and plays an important role in many areas such as data mining, pattern recognition, machine learning, bioinformatics and other fields. There are many clustering approaches proposed in the literature with different quality, complexity tradeoffs. Each clustering algorithm has its own characteristics and works on its domain space with no optimum solution for all datasets of different properties, sizes, structures, and distributions. Combining multiple clustering is considered as new progress in the area of data clustering. In this paper different combining clustering algorithms are discussed. Combining clustering is based on the level of cooperation between the clustering algorithms; either they cooperate on the intermediate level or end result level. Cooperation among multiple clustering techniques is for the goal of increasing the homogeneity of objects within the clustersKey words: Chameleon , Ensemble clustering, Generic and Kernel based ensemble clustering, Hybrid clustering, Reference [1] Cutting, D., Karger, D., Pedersen, J. and Turkey, J.W., "Scatter/Gather: A Clusterbased Approach to Browsing Large Document Collections," SIGIR '92, 1992, pp. 318-329.

Study of Existing Full Adders and To Design a LPFA (Low Power Full Adder)Abstract: This paper describes the different logic style used for CMOS full adders and different equation used to implement the required Boolean logic for full adders. This paper also describes that the speed of the design is limited by size of the transistors, parasitic capacitance and delay in the critical path. Power consumption and speed are two important but conflicting design aspects; hence a better metric to evaluate circuit performance is power delay product (PDP).The driving capability of a full adder is very important, because, full adders are mostly used in cascade configuration, where the output of one provides the input for other. If the full adders lack Driving capability then it requires additional buffer, which consequently increases the power dissipation. At last a new LPFA Design is proposed with comparisons between the various full adders to show the better performance of LPFA in terms of power consumption, area (number of transistors) and delay. The LPFA and all other various full adders are designed and simulated using mentor graphics tool in 0.18 μm technology. The frequency used is 100 MHz. the voltage and all the various full adders and others designs are simulated at a voltage supply of 1.8V at same frequency.Key words: CMOS Transmission Gate (TG), PassTransistor Logic (PTL), Complementary Passtransistor Logic (CPL), Gate Diffusion Input (GDI), LPFA (Low Power Full Adder), GDI based full adder Power, Delay Reference [1].

Modeling And Simulation of Gas Flow Velocity In Catalytic Converter With PorousAbstract: Stringent emission regulations around the world necessitate the use of high-efficiency catalytic converters in vehicle exhaust systems. Experimental studies are more expensive than computational studies. Also using computational techniques allows one to obtain all the required data for the Catalytic Converter, some of which could not be measured. In the present work, Geometric modeling ceramic monolith substrate with square shaped channel type of Catalytic converter and coated platinum and palladium using fluent software. In this software we are using crate inlet-outlet flanges and housing of the catalytic converter. After design of modeling us done different parameters in Fluent Preprocess like Analysis Type, Domain Type etc. This project studies the different porosity of porous medium how to affect to flow pressure field under the conditions of same inlet velocity and ceramic diameter by CFD method. Geometric model of the catalytic converter has been establish and meshed by the pre-processing tool of FLUENT. The flow pressure simulation filled contours and curve of center line static pressure distribution of the ceramic porous material show that in the case of other conditions remain unchanged, the less the porosity of the ceramic porous material, the higher the inlet pressure and the more the pressure loss of the porous material. The more Porosity of ceramic is beneficial to exhaust catalytic converter.Key words: Catalytic Converter, Ceramic material, CFX, FLUENT, Porous. Reference [1].

Criteria Interaction Modelling In The Framework Of Lca AnalysisAbstract: In this paper, we emphasize the possibility to aggregate evaluations by using different multi-criteria approaches and operators, actually more suitable for environmental problems. More precisely, values of different indicators, qualitative and quantitative, can be aggregate in a more flexible and efficient way, using operators not necessarily compensatory, allowing partial compensation and/or not transitive preferences, including also the very important possibility to model interactions among criteria. A single descriptor of multiple attributes, known as a composite indicator, can be used to reconcile apparently incommensurable criteria into a comparable basis, but the current aggregation and weighting practices in LCA are not sufficiently rigorous, because its methodological simplicity, usually being just weighted sums that implicitly require preference independence hypothesis and totally compensatory nature. We have explored different MCDA approaches in the literature that may be applied by LCA practitioners to enhance the technical credibility and also identify issues affecting the selection and implementation of a more appropriate aggregation approaches. In this direction, particularly attention can be devoted to some methods allowing the modelling of interaction, where suitable techniques can actually implemented in order to improve the validity of the resultsKey words: : Life Cycle Impact Assessment, impact categories, MCDA, interactions, weighting Reference [1].

Effect of variousEnergy inputs on Energy requirement for Wheat Production in Agro-Climatic Region (Kamore plateau and Satpura Hill), M.P. IndiaAbstract: Energy in agriculture is important in terms of crop production and agro processing for value adding. The energy requirement in various facets of agriculture varies considerably due to variation in the technology level adopted by the farmers and also because of the diverse agro-climatic conditions. The increased use of inputs such as fertilizer, irrigation water, diesel, plant protection chemicals, electricity etc. demands more energy in the form of human, animal and machinery. The aims of this study were to determine direct input energy and indirect energy in Kamore plateau and Satpura HillRegion,which belongs to wheat-rice zone of Madhya Pradesh, to investigate the efficiency of energy consumption. Data were collected from 120 farmer of Agro-Climatic Region by using a face to face questionnaire method. The results revealed that wheat production in year of 2010- 11 consumed a total of 14345MJ/ha of which chemical fertilizer, diesel fuel and electric energy consumption was 31.1%, 20.5% and 24.2%, respectively. Direct and Indirect energy were 49.6% and 50.4% respectively. Output Energy was 56595 MJ/ha. Output– input energy ratio and specific energy of production and productivity were 3.9, 3.7 MJ/kg and 0.27 kg/MJ, respectively. The use of commercial source is too high as compared to non-commercial energy sources. Commercial sources contributed about 93.4 per cent of total energy (14345 MJ/ha).On the basis of linear programming the prediction of energy requirement for different levels of yield reveals that there exist a significant scope to enhance wheat productivity through increased use of input energy through fertilizer and machinery. This is mainly due to the reason that still agricultural farms of Madhya Pradesh are applying 50-75% of recommendation of fertilizer and machinery use.Key words: Wheat, Energy ratio, Specific Energy, Yield, Productivity Reference [1].

Study of LF slag composition and its correlation with the desulphurisation and cleanliness aspect of liquid steelAbstract: Over the past few decades the demand for steel around the world has been increasing at a rapid rate, coupled with an increase in steel quality. One major technique for improving the quality of steel is to reduce its sulphur content. Sulphur is one of the most detrimental impurities in the steelmaking process, affecting both internal and surface quality. Desulphurization of steel at ladle furnace depends on temperature, amount of oxygen and sulphur in the steel, but mainly on chemical composition and physical properties of slag. Necessary requirement for effective desulphurization is also minimum amount of easy reducible oxides in the slag. There are many correlations for expression of slag desulphurization capacity, where their functional dependency on each other can be found. This paper presents graphical correlation of sulphur capacity with different parameters, correlation of slag colour with composition of slag ( FeO and MnO mainly) ,ternary diagram of slag having CaO , Al2O3 and SiO2 at constant 5% MgO from set of approximately 30 heats and area occupied by slag in ternary plot based on these, the parameters responsible for slag desulphurization capability are expressed using regression analysis of industrial data.Key words: Desulfurization, sulphur capacity, ternary diagram, regression analysis Reference [1] Secondary Steelmaking by Dr. Ahindra Ghosh [2] Fundamentals of Steelmaking by Dr. E.T.Turkdogan [3] Principles of Steelmaking by Dr. Brahma Deo [4] Slag Atlas by Verein Deutscher Eisenhuttenleute [5] Steel Making by Dr. R.H.Tupkary [6] Steel Plant Training Course Software [7] Math work by Matlab Thesis [8] Master Thesis on Improvement of the Desulphurisation Process in the Ladle Furnace by Slag Composition Control ( Dr.Stephen Famurewa Mayowa).

Biomedical Images denoising using Symlet Wavelet with Wiener filterAbstract: Various medical modalities like MRI, CT scan, Ultrasound Imaging have been widely used in medical diagnosis. From all these ultrasound imaging is most popular due to its non-harmful nature and lost cost. But there is a problem in ultrasound images that is speckle noise which effects diagnosis based on the ultrasound images by disappearing low contrast lesions in tissues. Many techniques like Filtering, Morphology, Histogram equalization and wavelets have been developed. From these wavelets based techniques performed better and give superior results. In this paper we discuss Symlet wavelet with Wiener filter technique to reduce speckle noise in ultrasound images. This technique gives better results than previous techniques by minimizing mean square error.Key words: Ultrasound Imaging, Speckle, Wavelet Transform, Symlet and Wiener filter.

Experimental study of the effect of hybridization on Mechanical Behavior of Jute/Glass Fibers Reinforced Polyester Composite MaterialAbstract: Natural fibers are being increasingly used to substitute artificial glass and carbon fibers in polymer composites. It is important to know how the mechanical properties of these natural fiber composites compare with those of the traditional glass and carbon fiber composites. Glass and carbon fiber composites are currently being used in many applications that may not require such high-strength materials a lower strength jute fiber composite may be adequate. Natural fiber composites are currently being used in mostly non-structural applications. The present work focus on the hybridization of natural fiber (jute) and synthetic fiber (glass) with polyester resin. Hybridization of jute fiber along with glass fiber produces better tensile and flexural strength than GFRPC and JFRPC at same wt. percentage of fibers.Key words: FRP Composite, JFRPC, GFRPC, HFRPC, Tensile Strength, Flexural Strength.

Micropolar Fluid Over A Heated Stretching Surface With Heat Generation/ Absorption
Effects Of Radiation On Mhd Mixed Convection Flow Of A Micropolar Fluid Over A Heated Stretching Surface With Heat Generation/ AbsorptionAbstract: A theoretical analysis is performed to study the flow and heat transfer characteristics of magnetohydrodynamic mixed convection flow of a micropolar fluid past a stretching surface with radiation and heat generation/absorption. The transformed equations solved numerically using the shooting method. The effects of the velocity, the angular velocity, and the temperature for various values of different parameters are illustrated graphically. Also, the effects of various parameters on the local skinfriction coefficient and the local Nusselt number are given in tabular form and discussed. The results show that the mixed convection parameter has the effect of enhancing both the velocity and the local Nusselt number and suppressing both the local skin-friction coefficient and the temperature. It is found that local skin-friction coefficient increases while the local Nusselt number decreases as the magnetic parameter increases. The results show also that increasing the heat generation parameter leads to a rise in both the velocity and the temperature and a fall in the local skin-friction coefficient and the local Nusselt number. Furthermore, it is shown that the local skin-friction coefficient and the local Nusselt number decrease when the slip parameter increasesKey words: Radiation, stretching surface, micropolar fluid, heat transfer, heat source.

| 99. | Reactivity of cement combinations containing Portland cement, fly ash, silica fume and metakaolin
Reactivity of cement combinations containing Portland cement, fly ash, silica fume and metakaolinAbstract: To examine the reactivity of cement combination, this paper investigated the Ca(OH)2 consumption of cement combination pastes containing Portland cement, fly ash, silica fume and metakaolin. Pozzolanic reaction is slow and it would take a long time to complete. Due to the disparity in their fineness, silica fume is more reactive than metakaolin and metakaolin is more reactive than fly ash. The Ca(OH)2 consumption per unit percentage of the cement additions reduced with increasing content with silica fume consuming more than metakaolin and metakaolin consuming more than fly ash. The Ca(OH)2 consumption of the cement additions, increased with increasing age and increasing fly ash content up to 35%. Hence, for optimum performance, fly ash as a binary cement should be limited to 35% content. Where higher reactivity up to 28 days is required, silica fume or metakaolin as binary cement components would perform better at 5% content than at 10% content. However, beyond 28 days, either 5% or 10% content could be used as there was no difference in the quantity of Ca(OH)2 consumed at both levels. The Ca(OH)2 consumption and reactivity of the ternary cement pastes is higher than that of the binary cement pastes. Also, the quantity of Ca(OH)2 consumed per unit content of the ternary cements increased with increasing content up to 10%. 15% would be more than the optimum content of metakaolin as both binary or ternary cement component.Key words: Blended cement; Ca(OH)2 consumption; cement combination; degree of hydration; pozzolanic reactivity.

Implementation of Carrier Synthesis Technique Using DPLLAbstract: DPLLs are used widely in communications systems like radio, telecommunications, computer and other electronic applications. Digital PLLs are a type of PLL used to synchronize digital signals. While DPLLs input and outputs are typically all digital, they do have internal functions which are dependent on analog signals. The main blocks in demodulator are DDS core, Filters, Arc tan estimator, Loop filter. The area reduction for onchip applications can be achieved through optimization of the number of micro rotations in proposed design. For better loop performance of second order complex DPLL and to minimize quantization error, the numbers of iterations are also optimized. Modelsim Xilinx Edition (MXE) and Xilinx ISE will be used simulation and synthesis respectively. The Xilinx Chipscope tool will be used to test the FPGA inside results while the logic running on FPGA. The Xilinx Spartan 3 Family FPGA development board will be used this project.Key words: Digital Signal Processing, DPLL, Micro-rotation, Loop performance, Arctan estimator. Reference 1.

Analysis of Code Tracking Technique in CDMANon Coherent ReceiverAbstract: In this paper, we propose and analyse a new non coherent receiver with PN code tracking for direct sequence code division multiple access (DS-CDMA) communication systems in multipath channels. We employ the decisionfeedback differential detection method to detect MDPSK signals. An "; error signal"; is used to update the tap weights and the estimated code delay. Increasing the number of feedback symbols can improve the performance of the proposed non coherent receiver. For an infinite number of feedback symbols, the optimum weight can be derived analytically, and the performance of the proposed non coherent receiver approaches to that of the conventional coherent receiver. Simulations show good agreement with the theoretical derivation.Key words: -Optimum weights, pn code, DS-CDMA Reference [1] Adaptive DS-CDMA Receiver with Code Tracking in Phase Unknown Environments Fang-BiauUeng, Jun-Da Chen, and ShangChun Tsai, Student Member, IEEE [2] Special Issue on the European Path Towards UMTS, IEEE Personal Communications, Vol. 2, No. 1, Febr. 1995.

Application of Univariate Statistical Process Control Charts for Improvement of Hot Metal Quality- A Case StudyAbstract: Statistical Process Control (SPC) techniques are employed to monitor production processes over time to detect changes. The basic fundamentals of statistical process control and control charting were proposed by Walter Shewhart. Shewhart chart can be used for monitoring both the mean and the variance of a process, however sensitivity of chart to shifts in the variance is often considered inadequate. So, it is common to use the chart coupled with either R chart or S chart, to monitor changes in mean and variance of process. This paper presents the application of univariate control chart for monitoring hot metal making process in a blast furnace of a steel industry for continuous quality improvement.Key words: Control Chart, Regression Analysis, Statistical Process Control, Univariate, chart Reference [1] Juran, J.

| 111. | Seismic Vulnerability Assessment Of Rc Buildings With Shear Wall
Seismic Vulnerability Assessment Of Rc Buildings With Shear WallAbstract: Reinforced concrete multi-storied buildings are very complex to model as structural systems for analysis. The current version of the IS: 1893-2002 requires that practically all multi-storeyed buildings be analyzed as three-dimensional systems. This is due to the fact that the buildings have generally irregularities in plan or elevation or in both. Seismic codes distinguish between regular and irregular configurations, and it is the latter that the irregularity may have a detrimental influence on the effectiveness and on the building seismic performance itself. The present analytical investigation proposes, discusses, and highlights the seismic performance of RC (Reinforced Concrete) buildings having dual system with emphasis on various case studies. The study includes seismic vulnerability assessment of RC buildings without shear wall, with shear wall at centre, shear wall at diagonal corners, shear wall at mid along X-direction, and shear wall at mid along Y-direction, lastly shear wall at mid along X&Y-directions.Key words: Seismic performance, evaluation, irregular RC building and shear wall,dual system Reference 1.

| 112. | A Novel Approach to Medical & Gray Scale Image Enhancement
A Novel Approach to Medical & Gray Scale Image EnhancementAbstract: Image enhancement is a mean as the improvement of an image appearance by increasing dominance of some features or by decreasing ambiguity between different regions of the image. Image enhancement processes consist of a collection of techniques that seek to improve the visual appearance of an image or to convert the image to a form better suited for analysis by a human or machine. Many images such as medical images, remote sensing images, electron microscopy images and even real life photographic pictures, suffer from poor contrast. Therefore it is necessary to enhance the contrast. The purpose of image enhancement methods is to increase image visibility and details. Enhanced image provide clear image to eyes or assist feature extraction processing in computer vision system. Numerous enhancement methods have been proposed but the enhancement efficiency, computational requirements, noise amplification, user intervention, and application suitability are the common factors to be considered when choosing from these different methods for specific image processing applicationKey words: Image Enhancement, Image Negation, Histogram Equalization, DWT, BPHE.

Real Time Automated Control using PLC-VB CommunicationAbstract: This paper is to enable the Delta PLC (Programmable Logic Control) DVP14SS to communicate with the Visual Basic 6.0. The communication between DVP14SS and Visual Basic 6.0 is via Modbus Serial Protocol. Computers are used as a link between humans and PLC systems as they have more graphics and visual capabilities. These are nothing but SCADA systems widely used for determining plant setups and displaying plant status on high quality screens. They also record/log the system data for long period .The SCADA software's are the software packages needs to be purchased from vendors and the cost depends on tag count. Visual Basic 6.0 platform can be used develop the SCADA application effectively. Using VB 6.0 we integrate software and hardware across spectrum of vendors easily. Here we show simple approach to communicate Delta PLC with visual Basic using MSComm control in visual basic.

Reliable Non invasive First Trimester Screening Test Using Image processing and Artificial Neural NetworkAbstract: Down Syndrome is a chromosomal abnormality caused by the presence of all or part of a third copy of chromosome 21.Any woman can have a baby with Down Syndrome. Physical growth of affected babies are delayed especially the facial characteristics. Recent study proves that Down Syndrome can be detected in early stage by identifying the absence of fetal nasal bone. During the first trimester of pregnancy, visual identification of nasal bone by examining the ultrsonogram is very difficult. Speckle noise is also introducing errors in ultrasonic images. This work presents a new approach for the detection of nasal bone by using different image processing algorithms and Back propagation neural network(BPNN).A high performance hybrid Despeckling method is used in this system which can dramatically increases the accuracy of the whole system. The features in the nasal region are extracted in spatial domain as well as transform domain using Discrete Cosine Transform (DCT) and wavelet transforms. Features extracted from images with nasal bone and images which don't have nasal bone. The normalized data set is used to train Back Propagation Neural Network (BPNN).This trained artificial feed forward network is used to classify different ultra sonogram. Experimentally prove that the proposed method gives better classification rate than any other non invasive screening method. This method combined with the present detection methods can reduce operator error and enhance overall detection rate.Key words: Back Propagation Neural Network (BPNN), DCT, Despeckling, First Trimester, Non Invasive Screening Reference [1] Nicolaides K.

Comparative Analysis Of Haar And Coiflet Wavelets Using Discrete Wavelet Transform In Digital Image CompressionAbstract: Images require substantial storage and transmission resources, thus image compression is advantageous to reduce these requirements. The objective of this paper is to evaluate a set of wavelets for image compression. Image compression using wavelet transforms results in an improved compression ratio. Wavelet transformation is the technique that provides both spatial and frequency domain information. This paper present the comparative analysis of Haar and Coiflet wavelets in terms of PSNR, Compression Ratio and Elapsed time for compression using discrete wavelet transform. Discrete wavelet transform has various advantages over Fourier transform based techniques.DWT removes the problem of blocking artifact that occur in DCT.DWT provides better image quality than DCT at higher compression ratio.Key words: Image compression, Discrete Wavelet Transform, wavelet decomposition, Haar, Coiflet, Blocking Artifact Reference [1] Kaleka,Jashanbir Singh., Sharma,Reecha.,"Comparativ performance analysis of Haar,Symlets and Bior wavelets on image compression using Discrete wavelet Transform", International journal of Computers and Dstrbuted Systems, Volume 1,Issue 2,August,2012 [2] Gao, Zigong., Yuan F.Zheng.

Effect of cement additions on the plastic density and workability of concreteAbstract: This paper reports the effect of cement combinations containing Portland cement, fly ash, silica fume and metakaolin on the plastic density and workability of concrete. The results show that cement additions would reduce the plastic densities of Portland cement concrete with increasing content. However, while fly ash binary cement concretes had plastic densities less than 2400 kN/m3 , silica fume and metakaolin binary cement concretes had plastic densities equal to or greater than 2400 kN/m3 . However, at a total replacement level less than 55%, all the cement combination concretes achieved plastic densities between 2350-2450 kN/m3 . Since fly ash reduced superplasticiser dosage and silica fume and metakaolin increased superplasticiser dosage, the superplasticiser dosages of the ternary cement concretes reduced with increasing content of fly ash. The cement additions improved the cohesion and stability of concrete. However, due to their increased surface area, concrete becomes sticky resulting in poor finish with increasing content of silica fume and metakaolin. Also, metakaolin concretes had higher plastic densities and required higher superplasticiser dosage than silica fume concretes at equal replacement level.Key words: cement additions; cement combinations; cohesion; finishability; plastic density; workability Reference [1] Antiohos S.

Implementation And Analysis Of Different Types Of Transmultiplexer StructuresAbstract: Multirate filter banks have become excellent solution for future wireless communication system. Filter bank based multicarrier system provides high spectral efficiency through removal of redundant information resulting in efficient use of available spectrum. In multicarrier communication system, filter bank based transmultiplexer (TMUX) having same analysis and synthesis filter bank is employed. The TMUX configuration which is core of any FBMC is of our interest here. This paper concentrates on implementation of filter bank based multicarrier/offset quadrature amplitude modulation (FBMC/OQAM). Different TMUX structures like maximally decimated, nonmaximally decimated and partial TMUX have been implemented. In partial transmultiplexer, upsampling and downsampling factor is less than number of sub channels. Frequency sampling technique is used for design of prototype filter and other filters are complex modulated versions of prototype filter. For all the TMUX structures perfect reconstruction is observed with alias cancellation. Further, computation of Intersymbol interference (ISI), Interchannel interference (ICI) will support filter designs for two-band and four-band TMUX. The Optimization criterion is applied to frequency sampling technique and results are compared based on ISI, ICI performance of TMUX.Key words: Transmultiplexer (TMUX), FBMC/OQAM, maximally decimated filter banks, non-maximally decimated filter banks, modified DFT filter banks, complex modulated filter banks, partial TMUX.

A Design of Fuzzy Approach for Data ClusteringAbstract: Data mining is the process of discovering patterns in large datasets. The objective of data mining is to extract information from a data set and transform it into an understandable structure for further use. Clustering in data mining is used to discover distribution patterns in the underlying data. Clustering aims to group data into clusters based on similarity/dissimilarity measures. Clustering algorithms uses the distance metric based similarity measure in order to partition the database such that data points in the same partition are more similar than points in different partitions. The clustering approaches differ in various aspects like flat or hierarchical structure, crisp or soft (fuzzy) cluster assignments.

Analysis of Adaptive Direct sequence Spread Spectrum using Least mean squares AlgorithmAbstract: Spread spectrum forms an important aspect of digital communication technology where the message signal is transmitted over a channel having bandwidth much greater than required. Direct Sequence Spread Spectrum (DSSS) belongs to the category of spread spectrum methods and forms an important part in mobile communications. The objective of this paper is to investigate the FIR optimal, Wiener and least mean square (LMS) algorithms in the design of traversal tap delay line filters for the purpose of compensating the effect of the quasi-static communication channel in mobile communication using DSSS. The designed equalizers remove the distortion caused by the channel from the transmitted signal with the help of an adaptive, recursive Weiner filtering technique using the concept of Weiner-Hopf equation using LMS algorithm and to aid in the equalization process, a training sequence is first transmitted to adapt the filter coefficients. The performance metrics are studied for DSSS system with and without adaptive equalization. Further, the convergence of LMS algorithm is also verified as well as the impact of different step-sizes on the speed of the conversion and the accuracy of the overall algorithm. Exhaustive Monte Carlo simulative analysis have been performed to investigate the scheme under varying distortion levels and Signal to noise ratio (SNR) values via impulse response, frequency response and uncoded Bit Error Rate (BER) simulations.Key words: Direct Sequence Spread Spectrum, Least Mean Square, Weiner-Hopf equation, Channel Equalization, Adaptive filter, Transversal tap delay line filters, Bit error rate.

| 122. | Development of Flow within a Diffusing C-Duct –Experimental Investigation and Numerical Validation
Development of Flow within a Diffusing C-Duct –Experimental Investigation and Numerical ValidationAbstract: Experimental investigation of flow development within a rectangular 90º curved diffusing C-duct of low aspect ratio and area ratio of 2 was carried out and the threedimensional computational results are then compared with the experimental results for numerical validation. All measurements were made in a turbulent flow regime (Re = 2.35x105 ), based on the duct inlet hydraulic diameter (dh = 0.0666m) and mass averaged inlet velocity of 60m/s. Wall pressures were measured through wall pressure taps. The mean velocities, static and total pressures at six cross-sectional planes (along the centreline of the diffuser) were obtained using a pre-calibrated three-hole pressure probe in null mode. The flow was numerically simulated by using different viscous models available in the commercial CFD software FLUENT 6.3. The experimental inlet and boundary conditions were used as input for the computation and validation of the numerical results. Based on the comparison, it is found that Standard k–ε turbulence model provides better prediction of flow field in the diffusing C-duct. Numerical results of coefficient of mass averaged static pressure recovery (61.6%) and coefficient of mass averaged total pressure loss (9.1%) are in good agreement with the experimentally obtained static pressure recovery and total pressure loss coefficients of 52.48% and 15.5% respectively.Key words: Aspect ratio, area ratio, coefficient of static pressure recovery, C-shaped diffuser, secondary motion, wall pressure.

Optimal Gear Design By Using Box And Random Search MethodsAbstract: The development of evolutionary algorithms plays a major role, in recent days, for optimal design of gears, so as to reduce the weight. In this study an optimal weight design (OWD) problem of gear is formulated for constrained bending strength of gear, tortional strength of shafts and each gear dimension as a NIP problem and solved it directly by keeping nonlinear constraint using Box and Random search methods, such that the number of decision {design} variables does not increase and easily get the best compromised solution. An extensive computer program in Java has been written exclusively for their purpose and is successfully used to obtain the optimal gear design.Key words: optimal weight design (OWD), NIP problem, Box Method, Random search method, Decision {design} variables.

| 125. | Strength Of Ternary Blended Cement Sandcrete Containing Corn Cob Ash And Pawpaw Leaf Ash
Strength Of Ternary Blended Cement Sandcrete Containing Corn Cob Ash And Pawpaw Leaf AshAbstract: The compressive strength of ternary blended cement sandcrete containing corn cob ash (CCA) and pawpaw leaf ash (PPLA) was investigated in this work. 105 sandcrete cubes of 150mm x 150mm x 150mm were produced with OPC-CCA binary blended cement, 105 with OPC-PPLA binary blended cement, and 105 with OPC-CCA-PPLA ternary blended cement, each at percentage OPC replacement with pozzolan of 5%, 10%, 15%, 20%, and 25%. Three cubes for each percentage replacement of OPC with pozzolan and the control were tested for saturated surface dry bulk density and crushed to obtain their compressive strengths at 3, 7, 14, 21, 28, 50, and 90 days of curing. The 90-day strengths obtained from ternary blending of OPC with equal proportions of CCA and PPLA were 11.30N/mm2 for 5% replacement, 10.90N/mm2 for 10% replacement, 10.60N/mm2 for 15% replacement, 10.10N/mm2 for 20% replacement, and 9.70N/mm2 for 25% replacement, while that of the control was 10.00N/mm2 . Thus, very high sandcrete strength values suitable for use in various civil engineering and building works could be obtained with OPC-CCA-PPLA ternary blended cement at longer days of hydration when good quality control is applied.Key words: Binary blended cement, corn cob ash, pawpaw leaf ash, pozzolan, sandcrete, ternary blended cement.

Statistical property based blind separation algorithmAbstract: A signal that is captured is usually a mix up of two or more original signals and so there is a need to separate them from original sources. It is effective, if this work is done automatically. The process of separating a set of signals from a set of mixed signals without any additional information is known as 'blind source separation'. This work focuses on an image of reflection. Here, we made use of an algorithm developed by Gai et al., This algorithm assumes that the mixtures are linear, with unknown linear mixing coefficients and unknown motions of sources in each image and it is based on the statistics of natural images. Besides the separation of the original sources, the method can automatically identify the number of original images and it has good results even in under-determined cases, where mixtures are fewer than layersKey words: Blind Separation, Moving Images, Image properties, natural image.

| 127. | Grid Interconnection of Renewable Energy Sources with Power-Quality Improvement Features at the Distribution Level
Grid Interconnection of Renewable Energy Sources with Power-Quality Improvement Features at the Distribution LevelAbstract: There is growing interest in renewable energy around the world. Since most renewable sources are intermittent in nature, it is a challenging task to integrate renewable energy resources into the power grid infrastructure. In this grid integration, communication systems are crucial technologies, which enable the accommodation of distributed renewable energy generation and play an extremely important role in monitoring, operating, and protecting both renewable energy generators and power systems. 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 inverter is controlled to perform as a multifunction device by incorporating active power filter functionality. The inverter can thus be utilized as: A) power converter to inject power generated from RES to the grid, and B) shunt APF to compensate current unbalance, load current harmonics, load reactive power demand and load neutral current. All of these functions may be accomplished either individually or simultaneously. With such a control, the combination of grid-interfacing inverter and the 3-phase 4-wire linear/non-linear unbalanced load at point of common coupling appears as balanced linear load to the grid. This new control concept is demonstrated with extensive MATLAB/Simulink simulation studies and validated through digital signal processor-based laboratory experimental results.Key words: power quality (PQ), distribution system, grid interconnection, Active power filter (APF), distributed generation (DG), renewable energy Reference [1] J.

Efficient Rare Association Rule Mining AlgorithmAbstract: Data mining is the process of discovering correlations, patterns, trends or relationships by searching through a large amount of data stored in repositories, corporate databases, and data warehouses. In Data mining field, the primary task is to mine frequent item sets from a transaction database using Association Rule Mining (ARM).Whereas the extraction of frequent patterns has focused the major researches in association rule mining, the requirements of reliable rules that do not frequently appear is taking an increasing interest in a great number of areas. Rare association rule refers to an association rule forming between frequent and rare items or among rare items. In many cases, the contradictions or exceptions also offers useful associations. Recent researches focus on the discovery of such kind of associations called rare associations. The mining of associations involving rare items is referred as rare association rule mining. Approaches to association rule mining uses single minimum support for identifying frequent associations. To mine interesting rare association rules, single minimum support approaches are not useful. Hence, we propose an algorithm based on MSApriori ,we call this new algorithm as MSApriori_VDB which uses vertical database format. Experimental results shows that our algorithms out performs previous approaches in both memory requirement and execution time by reducing the number of database scans.Key words: Data Mining, Association rules, Rare items, Rare Association rule mining, MSAPriri_vdb Reference [1] Agrawal, R. and R.

Analysis of Heat Transfer and Flow due to Natural Convection in Air around Heated Square Cylinders of Different Sizes inside an EnclosureAbstract: In this paper, analysis of heat transfer and flow due to natural convection in air around heated square cylinders of different sizes inside an enclosure has been computed. The square cylinder is at higher temperature and the vertical walls of the enclosure are at lower temperature with insulated horizontal walls. The various governing equations such as continuity equation, momentum equation, and energy conservation equation are calculated by finite elements using Galerkin method. Assuming constant properties of air, the Rayleigh number depends on the size of square enclosure for fixed high and low temperatures. The sizes of enclosures are taken as 20 mm, 40 mm, and 80 mm for different Rayleigh numbers. The size of the cylinder is taken accordingly for aspect ratio of 0.2, 0.3, and 0.4. Results are displayed in the form of Isotherms, streamline and velocity vector diagrams and the heat transfer and flow around the cylinder is analyzed.Key words: Aspect ratio, Finite Element Method, Fluent, Galerkin method Reference [1] A.Dalal, V.

Zone-Based Clustering Protocol for Heterogeneous Wireless Sensor NetworksAbstract: Wireless sensor networks (WSN) consist of hundreds or thousands of sensor nodes each of which is capable of sensing, processing, and transmitting environmental information. While wireless sensor networks (WSN) are increasingly equipped to handle more complex functions, innetwork processing still requires the battery powered sensors to judiciously use their constrained energy so as to prolong the effective network life time. There are a few protocols using sensor clusters to coordinate the energy consumption in a WSN. In this paper, we propose a Zone based Heterogeneous Energy Efficient Clustering (ZHEEC) protocol in order to balance the energy consumption among all nodes. In this protocol we have divided the network into various equal size zones. We have implemented ZHEEC protocol in network simulator: MATLAB. Simulation results show that our method outperforms LEACH in terms of network lifetime.Key words: – Clustering, Sensor Nodes, Residual Energy, Wireless Sensor Networks, Zones Reference [1] Imad Aad, Mohammad Hossein Manshaei, and JeanPierre Hubaux, "ns2 for the impatient", EPFL Lausanne, Switzerland, March, 2009.

Improvement In Performance Of Power Factor Correction Converters For Distributed Power SystemAbstract: In present situation, the power control of a DC load can be achieved via an AC-DC converter consisting of a rectifier bridge and a switching element (operating by sPWM technique). The use of such a converter causes a lot of high harmonics at the AC side, which reduce the power factor and distort the grid voltage. Using passive filter in the converter input to avoid the high harmonics consequences the power factor decrease. The increase in the utilization of computers, laptops, uninterruptable power supplies, telecom and bio-medical equipments has become uncontrollable as its growth is rising exponentially. Hence, increase in functionality of such equipments leads to the higher power consumption and low power density which provided a large market to distributed power systems (DPS). The development of these DPS posed challenges to power engineers for an efficient power delivery with stringent regulating standards; this is the motivation and driving force of this thesis. The objective is to minimize the switching losses of front-end converters employed in DPS, with the primary aim of achieving nearly unity power factor operation of converters.Key words: PWM, PFC, DPS, DC-DC converter, MOSFET, Active PFC Converter, Passive PFC Converter.

Experimental Investigation on Comparison of Performance Exhaust Emission and Characteristics using Diesel and Bio Diesel in Conventional Diesel Engine and Thermal Barrier Coated LHR EngineAbstract: Biodiesel is a clean- burning diesel replacement fuel made from natural, renewable sources such as new and used vegetable oils and animals fats. The biodiesel was characterized by determining its density results in combustion problems and hence it is proposed to used biodiesel in Low Heat Rejection (LHR) diesel engine to obtain efficiency. In this work biodiesel from Jatropha oil called as Jatropha Oil Methyl Ester (JOME) was used as sole fuel in conventional diesel engine and LHR direct injection (DI) diesel engine. The low heat rejection engine was developed with uniform ceramic coating of combustion chamber (includes piston crown, cylinder head, valves and cylinder liner) by Partially Stabilized Zirconia (PSZ) thickness of 0.5 mm thickness. The experimental investigation was carried out in a single cylinder water-cooled LHR direct injection diesel engine. In this investigation, the combustion, performance and emission analysis were carried out in a diesel and biodiesel fueled conventional and LHR engine under identical operating conditions. The test result of biodiesel fueled LHR engine was quite identical to that of the conventional diesel engine. The brake thermal efficiency (BTE) of LHR engine with biodiesel is decreased marginally than LHR engine operated with diesel. Carbon monoxide (CO) and Hydrocarbon (HC) emission levels are decreased but in contrast the Oxide of Nitrogen (NOX) emission level was increased due to the higher peak temperature. The results of this comparative experimental investigation reveals that, some of the drawbacks of biodiesel could be made as advantageous factors while using it as a fuel in the LHR diesel engine, and finally the analysis was found to be quite satisfactory.Key words: Biodiesel – Conventional Diesel, PSZ, LHR engine, Diesel engine.

A Review of recent work in wire electrical discharge machining (WEDM)Abstract: Wire electrical discharge machining (WEDM) is a specialized thermal machining process capable of accurately machining parts with varying hardness or complex shapes, which have sharp edges that are very difficult to be machined by the main stream machining processes. This practical technology of the WEDM process is based on the conventional EDM sparking phenomenon utilizing the widely accepted non-contact technique of material removal. Since the introduction of the process, WEDM has evolved from a simple means of making tools and dies to the best alternative of producing micro-scale parts with the highest degree of dimensional accuracy and surface finish quality. This paper reviews the vast array of research work carried out from the EDM process to the development of the WEDM. It reports on the WEDM research involving the optimization of the process parameters surveying the influence of the various factors affecting the machining performance and productivity. The paper also highlights the adaptive monitoring and control of the process investigating the feasibility of the different control strategies of obtaining the optimal machining conditions. A wide range of WEDM industrial applications are reported together with the development of the hybrid machining processes. The final part of the paper discusses these developments and outlines the possible trends for future WEDM research.Key words: Wire electrical discharge machining (WEDM);Process optimization; Cutting rate; Material removal rate; Surface finish Electric discharge machining (EDM), Metal removal rate (MRR), Surface roughness (SR) Reference [1] E.C.

Analysis of Power Flow Control in Power System Model using Thyristor Controlled Series Capacitor (TCSC)Abstract: The characteristic of a thyristor controlled series compensator (TCSC) is usually defined by the overall reactance of the device versus the firing angle of the TCR that is connected in parallel with a fixed capacitor. We represents a model control circuit by using microcontroller to generate trigger pulses to fire the gate of the thyristors according to the set firing angle for required output. It brings out the operation of TCSC along with numerical equations. It also gives impedance characteristics curve of a TCSC device and specifies the range of inductance and capacitance region and also finds a suitable value of inductance and capacitance. We analyze the different waveforms in the capacitive as well as inductive region of TCSC, optimal setting of TCSC is determined through the software code written in MATLAB.Key words: Firing angle, Thyristor Controlled Series Compensator (TCSC), Optimal Power Flow, Power system analysis, Zero Crossing Detector Reference [1] N.G.

Effect of natural rubber latex on strength and workability of fibre reinforced high-performance - concrete with metakaolin admixtureAbstract: To increase the applications of Natural Rubber Latex Modified Fiber Reinforced HighPerformance-Concrete (NRLMFRHPC) in India, greater understanding of NRLMFRHPC produced with locally available materials such as cement , Fine aggregates , coarse aggregates, Metakaolin and Crimped Steel fibers is essential. In the present investigation, NRLMFRHPC has been produced with locally available aggregates and mineral admixture (Metakaolin) and Natural Rubber Latex based NRLMFRHPC mixes were designed by absolute volume method. Cubes of 150X150X150 mm in dimension were cast and cured for 28 days and then tested for compressive strength to assess the strength characteristics of NRLMFRHPC. Workability has been measured by conducting compaction factor test on fresh NRLMFRHPC mixes. The experimental results indicate that Natural Rubber Latex can be utilized in producing durable Fiber Reinforced HighPerformance-Concrete. The various results which indicate the effect of Steel Fibers and Natural Rubber Latex on the strength and workability characteristics of highperformance-concrete are presented in this paper to draw useful conclusions.Key words: Metakaoline, Natural Rubber Latex, Steel Fibers, High Performance Concrete.

Performance comparison of AODV and DSR under various network conditionsAbstract: Mobile ad hoc networks (MANET) are self-created and self organized by a collection of mobile nodes, interconnected by multi-hop wireless paths in a strictly peer to peer fashion. Ad-Hoc routing protocols such as Dynamic source routing (DSR), Ad-hoc on demand distance vector (AODV) and Destination sequence Vector (DSDV) has been proposed to solve the routing problem in Ad-hoc networks. Extended research has been done in comparing the different proposed ad-hoc routing protocol under various network conditions. Packet delivery ratio (PDR), routing overhead, path optimality, end to end delay and throughput are some parameters commonly used in the comparisons. This survey paper provides the analyzed performance of the routing protocol under the various conditions.Key words: MANET , AODV, DSR, Throughput.

Mathematical Models for drying behaviour of green beansAbstract: Drying is the oldest methods for prevention of the Agricultural products such as fruits and vegetables. Green Beans have a significant share in vegetables production in the world. It is also important raw material for many food products. Temperature velocity and relative humidity of drying air are important parameters for hot air drying process. Drying characteristics of green beans were examined for average moisture content from 90.53 ± 0.5% to 14 ± 0.3% using hot air of the temperature range of 50 0C. The experimental drying curves obtained were fitted to a number of semi-theoretical models, namely Handerson and Pabis, Lewis and page models. Comparing the determination of coefficient, reduced chi-square and root mean square values of three models, it was concluded that the page model represents drying characteristics better than others. The effective diffusivity coefficient of moisture obtained as 2.641 * 10-9 m2 / s over the temperature range.Key words: Drying rate; Modelling; Effective diffusivity, Equilibrium Moisture content.

Queue Balancing Dynamic Resource Allocation Management in CR networksAbstract: In Future wireless communication and networking Cognitive radio is a powerful technology. It is a new communication paradigm in spectrum. When the spectrum is left unused by the licensed users it allows the unlicensed users to access the spectrum efficiently. However the secondary users vacate the current occupied channel the specific primary users for that channel to transmit data by that channel itself because the primary users have the priority to access the channel. To provide reliable transmission to the secondary users, spectrum hand off method is help the secondary user return the channel to the specific primary users and stop the secondary user's transmission and the remaining transmission of the secondary user at other free channel. The problem is allocating channels and transmission power in multihop CR networks. This research paper proposed a frequent feature selection method for CR networks. Good performance of this method comes from the use of the spectrum utilization. The proposed approach improves the data transmission accuracy and reduces the packet loss of the secondary user transmission.Key words: cognitive radio (CR),Muihop networks. Reference [1] J.

Power Flow Control In Induction Motor By Using Assymmetrical Multilevel InverterAbstract: The Assymetrical multilevel inverter topology is used for the optimization of levels with a mimimum no. of voltage sources. It is used where medium voltage and higher power is required.There are three or four H-bridge of single phase inverter (consist of MOSFET or Optocoupler)connected to Induction motor.All H-Bridges are working with different votage sources bases on the G.P ratio(2or3).A multilevel inverter is more advantageous in comparison with a conventional two-level converter that uses high switching frequency pulse width modulation(PWM).The increase in the number of level in multilevel inverter reduces the total harmonic distortion (THD),common mode voltages,the output filters and the switching losses and hence power flow can be controlled by providing smooth a.c sine wave to the induction motor to mainly prevent the reduction of the efficiency of the motor due to harmonics which are present in normal power supply.But in multilevel there are also some limitations if we will go for higher levels i.e.beyond 27 level that we will also see here in detail description by the results of simulation done on MATLAB7.10.Key words: Assymetrical multilevel inverter, MOSFET, Optocoupler, Induction motor,HBridge(consist of MOSFET),G.P ratio, Conventional two-level converter, PWM,THD, common mode voltages,output filters, switching losses, harmonics, ac sine wave, efficiency, simulation Reference [1].

Phenylalanine Imprinted Microbeads Prepared by Shaking MethodAbstract: Molecularly imprinted polymer (MIP) technology is an emerging tool for the separation and isolation of structurally related compounds. MIP beads are considered useful in HPLC, CC, SEC, TLC, drug delivery systems as well as in chemical and biosensors. In this work a new shaking method using baffle flask as reactor for suspension polymerization for the preparation of MIP microbeads has been developed. This attempt proved to be simple, cheap and has greatly reduced the chances of oxygen entrapment during polymerization process. Characterization of the prepared nonimprinted beads (NIBs), D-Phe imprinted beads (DIBs) and L-Phe imprinted beads (LIBs) was made with SEM and FTIR analysis. Round shape, porous structure beads with a size distribution of 1-12 µm have been synthesized. The prepared DIBs and LIBs were used for the separation of D, L-Phe racemic mixture and showed good adsorption capacity (0.109 and 0.128 mg/g respectively) and adsorption selectivity (1.271 and 1.303 respectively) compared to NIBs with adsorption capacity 0.063 mg/g and adsorption selectivity 0.969.Key words: D-Phe imprinted microbeads, L-Phe imprinted microbeads, shaking method Reference 1.

Study of Stress Relief Features at Root of Teeth of Spur GearAbstract: Spur gear is cylindrical shaped gear in which the teeth are parallel to the axis. It is easy to manufacture and it is mostly used in transmitting power from one shaft to another shaft up to certain distance & also used to vary the speed & Torque. The cost of replacement of spur gear is very high and also the system down time is one of the effect in which these gears are part of system. Failure of gear causes breakdown of system which runs with help of gear. When gear is subjected to load, high stresses developed at the root of the teeth, Due to these high stresses, possibility of fatigue failure at the root of teeth of spur gear increases. There is higher chance of fatigue failure at these locations. So to avoid fatigue failure of the gear, the stresses should be minimized at maximum stress concentrated area. Design of spur gear can be improved by improving the quality of material, improving surface hardness by heat treatment, surface finishing methods. Apart from this stress also occurs during its actual working. Hence it is important to minimize the stresses. These stresses can be minimized by introducing stress relief features at stress zone. Many simulation packages are available for checking the different values of stresses. Simulation is doesn't give exact results but gives a brief idea where stresses are induced. Hence experimental stress analysis method can also be adopted for studying stresses.Key words: Spur gear, Stress, Simulation, Ansys Reference 1. Andrews J.D.

Design and Modification of vacuum braking systemAbstract: Vacuum brakes are first used in place of the air brake in railway locomotives. This braking system uses a vacuum pump for creating vacuum in the brake pipe. The integral construction of the brake cylinder uses this vacuum reservoir for the application of brakes. Nowadays most of the light vehicles are fitted with vacuum-assisted hydraulic braking system where vacuum is created from the engine which reduces the driver effort on foot pedal. The vacuum braking system was modified from above said reasons and the same was tested for implementation in both light and heavy vehicles. In this work, vacuum is created and used for the application of brakes. The system operation is somehow similar to air braking system. The main difference with air brake system is that vacuum is used instead of compressed air. The design and modified system also includes the Vacuum brake system i.e., the loss of vacuum will cause the brake to be applied due to spring force.Key words: Air braking system, Fail safe condition, Heavy vehicle, Hydraulic brake, Light vehicle, Vacuum braking system .

Improving The Performance Of Congestion Control In Wireless NetworksAbstract: The Transmission Control Protocol (TCP) provides an end-to-end, ordered transmission of data over a logical connection which links two applications during their communication.TCP is a mainly concerned with moving data between applications and it uses the routing services provided by IP. The most widely used Internet protocol in the present days is TCP. It should have the knowledge of locating the applications and it need not know about the topology of the network. TCP actually takes the data from the source application and delivers to the destination application.TCP is mainly designed for using with unreliable systems such as IP, which only gets the data from one host to another and perform less error checking. The important feature of TCP with respect to its performance is congestion control algorithm.TCP mainly uses a number of techniques for achieving high performance and avoiding congestion collapse, which makes the network performance to fall by several levels of magnitude. The TCP congestion avoidance algorithm is the primary basis for the control of congestion.Key words: Congestion Control, TCP, Internet Protocol. Reference [1] J.

A Review On Mechanical AlloyingAbstract: Ball milling is one of the most extensively used technique to produce ultrafine materials. The ball milling process is widely used in ceramic and metal processing industries. Ball milling consists of repeated fracture, mixing, and cold welding of a fine blend of metal, oxide, and alloy particles resulting in size reduction and sometimes in chemical reactions. In recent years the ball milling process is employed to prepare nanostructured materials which are intensively studied, particularly because the physical and chemical properties of these materials are quite different from those of the bulks material. In nano-materials research, this technique is well used to fine-tune the grain sizes of the materials in nano-scales. However scientists and engineers are optimizing the processing parameters and machine construction to obtain powders with desired size and performance characteristics. The purpose of this work is to review the findings of some of the researchers, relevant to the ball milling process for soft magnetic materials such iron, cobalt and nickel and to emphasize the importance of key process parameters on grain size, particle size and performance characteristics.Reference 1.

Clustering students' based on previous academic performanceAbstract: Educational data mining is very popular research area for studying the behavior of students based upon their past performance. As Education is very basic need, which must be given to all, the study of student behavior plays a vital role. Grouping students on the basis of their performance, we can make a good team for any competitions to represent from institute or university. Also we can make some more focus on the students who are having bad performance by giving some extra lectures and motivating them for better study. In this paper, we will cluster the similar behavior students based upon their past academic performance. We are using Similarity measure as Canberra Distance for clustering same type of students. We will use VIT university data for analyzing performance.Key words: Educational Data Mining, Clustering Students, Grouping Method, Students behavior. Reference [1] Kartik N.

In distributed database, large amount of database required quick response to the user which can enhance the query processing. A data warehouse is the collection of materialized views which are used to process a given set of queries. Materialized views are found useful for fast query processing. It can be the result of a query, subset of the rows or column or can be the join result. Instead of accessing the original database , some immediate result can store in the form of materialized view which can give the fast access to the data .There are two issues should be consider while developing materialized views i.e. space constraint & maintenance cost constraint .Because materialized view required large amount of space on to the disk, materialization of all queries or views are not possible. Therefore Materialized views selection is one of the important decisions in designing a data warehouse. This work will implement an algorithm which can select the queries based on frequently accessing by the user & materialized that query so that user can get fast access to there useful data & automatically query processing will be faster and maintenance of data in order to get up-to-date information..Key words: Data warehouse, materialized views, maintenance cost, query processing cost.

Design, Synthesis And Simulation Of Four Bar Mechanism For Eliminate The Plowing Depth Fluctuations In TractorsAbstract: In this paper, a four bar mechanism was designed for the specified performance output for a tractor. In tractor's plowing is engaged with the assistance of a hydraulic cylinder. Looking on the soil hardness the plowing depth fluctuates that isn't fascinating. To induce the correct plowing depth an Electrical control system is introduced. It consists of hydraulic valve, control unit and also the angular sensor. The control system helps to regulate the plowing depth accurately. The device measures the position of pivot and offers feed back to the system. Thus a sturdy, reliable and safe link mechanism is developed to measure the angular motion of the pivot. The main focus of this paper is to analyze Dimensional synthesis is performed supported Freudenstein's Equation and Chebechev's formula in Matlab and calculate the structural error of linkage mechanism by using Adams.

An Electronic tongue for core taste identification based on conductometryAbstract: This paper presents a method for identification of basic tastes, i.e. sweet, sour, bitter and salty with the help of electronic tongue. The electronic tongue works on the basis of conductometric technique and having two electrodes. This technique determines the concentration of ions in solutions in terms of current flow as a function of voltage when polarization of ions occurs around the electrode. This measured current is a function of different chemical composition and hence can be used for the identification of different taste, as different taste having different chemical composition. The main objective of the present work is to test samples from four different tastes with the help of electronic tongue and analyzing the output current obtained from different solution in time domain.Key words: Electronic Tongue, Basic Test, Conductometry, Electrode.

Enterotoxigenic Profiles of psychrotolerant and mesophilic strains of the Bacillus cereus group isolated from food in MoroccoAbstract: The species Bacillus cereus, known for its ability to cause food borne disease, consists of a large variety of strains. An important property for discrimination of strains is their growth temperature range. Fifty-two strains of Bacillus cereus isolated from different sources of food (milk, dairy product, spices and rice salad) for two years were determined to be either mesophilic or psychrotrophic by growth at 6 °C and at 43° C on optimal agar medium. The strains were also screened by real time polymerase chain reaction to discriminate between mesophilic and psychrotrophic types. The result obtained allowed highlighting eight profiles. Thirty seven of the 52 strains were able to grow at 6°C, but only thirteen conformed to the new psychrotolerant species Bacillus weihenstephanensis. The presence of the gene components encoding production of enterotoxins Nhe, Hbl, EntT and a recently described cytotoxin K was determined by PCR. All the strains possessed genes for at least one of these toxins. The nhe genes were detected in a higher proportion than hbl genes. Haemolytic enterotoxin was detected in 71.1 per cent of the isolates. Results of this study indicate that there are intermediate forms between B. cereus and B. weihenstephanensis, these results might be of importance for gaining further understanding of the growth properties of B. weihenstephanensis and psychrotolerant B. cereus as well as their contribution to food poisoning. However, no relationship among haemolysis test, enterotoxin genes and growth temperatures of the strains was found.Key words: Bacillus cereus group, mesophilic, Morocco, psychrotolerant, virulence genes Reference [1] Adams, MR., Moss, MO.

Analysis Of Face Recognition- A Case Study On Feature Selection And Feature NormalizationAbstract: In this the effects of feature selection and feature normalization to the face recognition scheme is presented. From the local features that are extracted using block-base discrete cosine transform (DCT), three feature sets are derived. These local feature vectors are normalized in two different ways by making them unit norm and by dividing each coefficient to its standard deviation that is learned from the training set. In this work use local information by using block based discrete cosine transform. Here the main idea is to mitigate the effects of expression, illumination and occlusion variations by performing local analysis and by fusing the outputs of extracted local features at the feature and at the decision level.Key words: Image Processing, DCT, Face recognition; Reference [1].

Contribution of Transparent cryptography in prevention of information leakageAbstract: The aim of this paper is to analyze how transparent cryptography protected digital content of mobile in an effective way. In this chapter we will look for possibilities to use transparent cryptography for AES in a secure way. We discuss an application of transparent cryptography in which we split the set of white-box tables into a dynamic part and a static part . The result is that whenever a key needs to be updated, no longer the whole set of tables needs to be updated. In §6.3 different possibilities for using external encodings are described. We discuss what the best possibility .we discuss the problem of the storage space and we look for possibilities to use less tables to save storage. Finally, we look for possibilities to use transparent cryptography for OMA-DRM.Reference [1] D.

Mathematical Modelling of Solar Air HeaterAbstract: Mathematical modeling has become an accepted tool for predicting the performance, and optimization of thermal processes. Solving the mathematical models representing solar air heating process and systems is one of the most tedious and repetitive problems. Mathematical modeling of conventional solar air heater with single glass cover is presented. Calculations for a collector of aperture area 2m2 have been done for Chennai. It has been found that at solar insolation of 734 W/m2 , average temperature of outlet air is 328.352K (55.32˚C) i.e. rise in temperature of air through the collector is 8˚C for air flow rate of 440 kg/h, Instantaneous efficiency of collector is found as 51.8 % and the pressure drop is 36.982 Pa. Results are closely matching with such experimental results. Finite Difference Method can also be used to solve heat transfer equations for conventional solar air heaters.

| 175. | Theoretical And Experimental Analysis Of Corroded Pipe Strength
Theoretical And Experimental Analysis Of Corroded Pipe StrengthAbstract: Process industries have vast networks of pipelines. Those pipelines are prone to external and internal corrosion. Usually environmental conditions and other operating factors cause corrosion. Although there are various ways to protect corrosion but it is inevitable. It may lead to uniform material loss of the wall thickness or pitting, which corresponds to the local wall thickness reduction or general form of cavitations. Corrosion cavity can appear as simplified or in other general form as shown in Fig. 1. These corrosion defects can appear externally as well as internally. Corrosion reduces strength of pipe leading to risk on production, facilities and even human life. To avoid failures due to corrosion and ensure safe and continued operation, corrosion has to be detected and measured. The strength of these corroded areas has to be determined to ensure safety of pipeline, facilities and human life. In this paper different theoretical method are mentioned which are used to evaluate pressure carrying capacity corroded pipe. And also brief information is added about experimental validation of analytical methods. It is very important to carry out periodic assessment and inspection of the pipeline by assessing remaining strength of corroded pipe.Reference 1. Belachew C. T., Mokhtar C. Ismail, and Saravanan K.

Flexible Windows Design Preferred by Homeowners: a Survey of Universiti Teknologi Malaysia Staff MembersAbstract: User-oriented home construction necessitates participation on the part of the user in the initial design stage of gathering feedback regarding performance. The gap between designers and users, and time considerations means that developing flexible windows is a coping strategy for encouraging user participation and ensuring quality products that are economical and fully sustainability. This study investigated flexible window design based on the principles of design for disassembly and the relationship between the expectations of prospective users and windows features by understanding user motivations, what features they expected and the need for flexible windows. To achieve these goals, a self-administered questionnaire was given to Universiti Teknologi Malaysia staff. The results indicated that the best configuration for flexible windows had few parts, were easy to operate, had a simple structure, and could be quickly installed, were important while selecting windows. Moreover, a variety of designs, ease of maintenance, reusability and lightness of construction materials were additional appreciated factors. Slider windows and windows made of wood were the most preferred in terms of structure and construction material. The features expected by the users served as the basic knowledge that could be used to adopt an appropriate development perspective for the intended users.Key words: Flexibility; design for disassembly; flexible windows design; user expectation; survey; Malaysia Reference [1].

| 177. | FPGA Implementation of Radio Navigation Based on MicroBlaze
FPGA Implementation of Radio Navigation Based on MicroBlazeAbstract: In moderm aviation, navigation is an important technology. So far, equipped in almost all the military and civil airports, radio navigation system is the most widely used navigation devices in aviation. At present, radio navigation still has priority in short-range navigation of civilian and military aviation in our country. Also, due to the imperfect landing system device in the existing aircraft, radio navigation system is of vital importance in ensuring safety in Plane's homing and approaching. In the actual navigation test, to simulate the RF signal of combined antenna in radio navigation, various signal generators are often designed to satisfy performance of navigation system and meet technical requirements. Meanwhile, the signal generator must adjust signal types, parameters and work modes timely according to the navigation system requirements. Therefore, signal generator must have the feature that signal can be generated flexibly, parameters change quickly, signal spectrum stay stabilized, and the system is reliable, etc. The proposed system adopts Micro Blaze soft processor as the control core of generator to communicating command with PC. which can satisfy each requirement in actual application of testing and debugging on navigation. The important role in navigation test, radio navigation generator is widely used in the people/military plane. But traditional equipment composed of analog circuit Presents low accuracy and poor reliability. A new kind of digital navigation signal generator is designed. It receives data and commands from PC by MicroBlaze embedded soft processor of Xilinx Company and demodulates information to control FPGA load different softwares to generate various navigation signals, which fully meets general radio navigation system test technical requirements by giving full play to the system hardware and software advantages and fulfilling design targets such as the accuracy, flexibility and expansibility. Therefore, providing a new idea for radio navigation system. this generator can be widely applied to debugging use on people/military plane radio navigation. Using FPGA instead of an ASIC gives also flexibility for reconfiguration, which is a need for the Software Defined Radio (SDR) concept. Modelsim Xilinx edition will be used for simulation. The Xilinx ISE will be used for synthesis; place & route and bit file generation. Xilnix Spartan 3E family FPGA board will be used testing the logic. The chipscope pro analyzer is used to display the captured set of results.Key words: DDS signal generation, UART,FPGA, Micro blaze.

Optimization of extrusion processing conditions for preparation of an instant grain base for use in weaning foodsAbstract: The purpose of this study was to investigate the effect of process conditions on the properties of instant grain base. A blend of wheat, mungbean and groundnut was used in the study. The effects of feed moisture, barrel temperature and screw speed on product responses viz. specific mechanical energy (SME), expansion ratio (ER), density (D), water absorption index (WAI) and water solubility index (WSI) was studied using response surface methodology.The blend was extruded at different moisture content (12.6 -19.4%), screw speed (349 - 601 rpm) and barrel temperature (116 - 184°C). The regression models for SME, expansion ratio, bulk density, WAI and WSI were highly significant. SME has been found to decrease with increase of moisture and temperature and increased with increase in screw speed. Expansion ratio and density were significantly affected by feed moisture and temperature. WAI and WSIwere found to decrease significantly with increase in moisture content and increased significantly with increase in Screw speed and temperature.The optimum values for moisture content, screw speed and temperature were 14.08%, 521 rpm and 140oC respectively. The desirability was found to be 0.835 for this model.Key words: Weaning, Optimization, Wheat, Mungbean, Groundnut, Extrusion Reference [1] R. Bressani, J.M. Harper and B.

Optimizing the Use of Sodium Polyacrylate in Plain ConcreteAbstract: This study focusses on the use of an optimum amount of Sodium Polyacrylate, SP, to be mixed in ordinary plain concrete. SP has two major effects on concrete. The first is to provide internal water source that helps in the hydration process, and curing and ultimately increases the concrete strength. The second effect is providing additional voids, due to drying process, in the concrete mass. These voids affect the concrete strength negatively; at the same time improve the concrete performance by improving the concrete workability and placeability, reducing the concrete susceptibility to freezing thawing cycles, reducing shrinkage, and improving the fresh concrete stability. The main focus of this study will be on the concrete strength. Several batches were prepared to determine the most effective amount of SP to use in the concrete mix.Key words: Concrete Durability, Hydration, Internal Curing, Sodium Polyacrylate Reference 1.

A Machinability Study of Mild Steel using Abrasive Water Jet Machining TechnologyAbstract: Abrasive water jet machining is a non conventional machining process in which removal of material takes place by impact erosion of high pressure, high velocity of water and entrained high velocity of grit abrasives on a work piece. The objective of experimental investigation is to conduct research of machining parameters impact on Material removal rate and Surface roughness of work piece of Mild Steel (MS). The approach was based on Taguchi's method, analysis of variance and signal to noise ratio (SN Ratio) to optimize the Abrasive Water Jet Machining process parameters for effective machining and to predict the optimal choice for each AWJM parameter such as Traverse speed, Abrasive flow rate, and Standoff distance. There is L9 orthogonal array used by varying Transverse Seed, Abrasive flow rate, standoff distance respectively and for each combination we have conducted three experiments and with the help of Signal to Noise ratio we find out the optimum results for AWJM. It was confirmed that determined optimal combination of AWJM process parameters satisfy the real need for machining of Mild Steel (MS) in actual practice.Key words: Abrasive Water Jet Machining, Garnet, Mild Steel Reference 1.

Controlling Temperature of water Using Microcontroller And Correction Using Fuzzy LogicAbstract: Many people of our country is involve in fishery, but different fish live in different temperature and pressure if the temperature vary the fish may be die, so the temperature must maintain within certain range but it is very difficult for them to maintain the temperature and pressure, if they try to maintain all the parameter the cost also higher, so we must think a alternate process which is our desire project. In this project we basically control the water temperature using microcontroller PIC18F4520.We first measure the water temperature of the water and then display it in the seven segment display now if the temperature is higher than on the cooler and if the temperature is lower than on the hot air fan. We also use fuzzy controller to control the water temperature and pressure perfectly. To program the microcontroller we first write the program in C-language, and then we convert the code in the hexadecimal code and burn the code within the chip and configure the microcontroller according tKey words: Fuzzy Logic, Microcontroller, PIC18F4520, RS232, Lampex Display Reference [1] http://www.egr.msu.edu/classes/ece480/go odman/ForMinipro [2] jects/Lab3.pdf [3] http://www.egr.msu.edu/eceshop/Parts_In ventory/datasheets/74ls12. pdf [4] http://www.egr.msu.edu/eceshop/Parts_In ventory/datasheetZ/sn7407 .pdf [5] http://www.egr.msu.edu/eceshop/Parts_In ventory/datasheets/sn7407. pdf [6] http://ulcape.org/wiki/TutorialPIC_Programming_Basics [7] A.

Business Cycles Synchronization Assessment: AnEBA-Wavelets ApproachAbstract: This paperuses an Extreme Bound Analysis (EBA) and Wavelet Transformation (WT) to provide a detailed characterization of the Business Cycle Synchronization (BCS) within the selected countries belonging to the Euro Area (EA) and Gulf Cooperation Council countries (GCC). In addition, a cross wavelets transformation and wavelets coherency transformation analysis is introduced in order to understand how wavelets could be used in BCS leading likely to achieve high levels of economic activity integration betweencountries or groups of countries. The analyses are conducted by introducing the main determinants of BCS existing in the literature in order to understand how they could evolve both in time and in scale as far as the difference phases of the economic system construction is concerned. Globally, and unlike the EA, the results show not only a considerable delay in creating an economic and financial integration in the GCC, but more importantly, a growing divergence in business cycles (BC) among the GCC countries.Key words: Business Cycles, Extreme Bounds Analysis, Synchronization, Wavelets.

A Microcontroller Based Electric Cooker/Oven with Temperature and Time Control for the Developing CountriesAbstract: This article presents the development of a novel microcontroller based electric cooker/Oven with time and temperature control. It employs the rich application of ATmega8- microcontroller as the core component. The system is software driven through the Clanguage code written to the microcontroller. Temperature control is achieved using a temperature sensor (LM35). The sensor monitors and measures the temperature of the system, keeping it at a preset value. The internal timing function of the microcontroller is used to time the cooking, baking or drying process. This whole cycle of temperature and time control is repeated until the set time elapses or until the item being cooked, dried or baked is ready (that is when the time is set to infinity mode). These processes conserve power and essential food nutrients. The cooker/oven is a cutting edge innovation and it is efficient, reliable and user friendly.Key words: MEnergy conservation, microcontroller, control, efficiency Reference [1]. Adiya, P. M. (1989).

Gene Expression Programming Based Dataset Decoration for Improved Churn PredictionAbstract: Mobile network operators rely on business intelligence tools to derive valuable information regarding their subscribers. A key objective is to reduce churn rate among subscribers. The mobile operator needs to know in advance which subscribers are at risk of becoming churners. This problem is solved with classification algorithms having as input data derived from the large volumes of usage details recorded. For certain categories of subscribers, available data is limited to call details records. Using this primary data, a dataset is created to be conveniently used by a classification algorithm. Classification quality using this initial dataset is improved by a proposed method for dataset decoration. Additional attributes are derived from the initial dataset through generation, based on gene expression programming. Classification results obtained using the decorated dataset show that the derived attributes are relevant for the studied problem.Key words: - business intelligence, churn prediction, classification, data mining, gene expression programming Reference [1] A.

Enterprise Systems and Labor Productivity: Disentangling Combination EffectsAbstract: This study analyzes the relationship between labor productivity and the three widely established enterprise software systems, i. e. Enterprise Resource Planning (ERP), Supply Chain Management (SM) and Customer Relationship Management (CRM), revealing performance gains incurred through the varying combinations of the systems with an exclusive focus on complementarities and interactions among them. Using German firm-level data, the results show that the highest productivity gains based on enterprise system usage are realized through the use of the three enterprise software systems in concert and not by relying on one or two of the systems alone. Concerning complementarity the results indicate that SCM and CRM function as complements if the firms already have an ERP System running or get the system in conjunction. The results stay robust to different model specifications and complementarity testing procedures.Reference [1]. Aral S, Brynjolfsson E, Wu D J (2006) Which came first, IT or productivity?

Preservation Of Privacy And Integrity In WSN With Safeg ProtocolAbstract: In two-tiered wireless sensor networks, storage nodes play an intermediary role between the sensors and the sink node. These storage nodes store data and processes queries. This technique preserves power and the memory for sensor nodes, as everything is managed by storage nodes including query processing. This importance of storage nodes grabs attackers to intrude storage node in order to affect its integrity and privacy. Thus, there is a need to protect storage node and we propose a new protocol named 'SafeG'. If storage node is protected then, the attacker cannot infer about the data present and also the queries passed by sinks. SafeG provides both privacy and integrity. SafeG encodes both the data and query and so the encoded query acts upon encoded data. SafeG relies on authentication chain to provide integrity.Key words: - Integrity, Privacy, Authentication.

Lossless Compression in MPEG4 VideosAbstract: This work considers object repetition, which means the occurrence of same object with similar motion is repeated in two or more frames. A single video is divided into several frames. All the objects are extracted from the stationary background and their features like motion and shape are preserved. After extraction, a two step compression is employed in which the algorithm checks for the continuous motion of all objects and then the video sequence are segmented. Now, the segmented video is compressed. This methodology maintains the video quality of the compressed video to be the same as source video.Key words: Video, Compression.

The Effect Of Cooling Rate On Cyclic Stress Strain Response Of Al-2024Abstract: Cyclic stress strain curves (CSSC) response of Al-2024 Annealed condition was conducted under symmetric tension-compression at room temperature and constant frequency, using a servo-hydraulic testing machine, to study the effect of cooling rate on cyclic stress strain curves (CSSC) response. The fatigue response of Al-2024 alloy was evaluated macroscopically in terms of cyclic stress strain response and microscopically in terms of appearance of precipitations free zones. It was found that the cyclic stress strain response of air-cooled specimens group exhibited a higher saturation stress with plastic strain and smaller PFZ regions whereas the cyclic stress strain response of furnace cooled specimens group exhibited a lower saturation stress and larger PFZ region. Both types of the cooling rates were showed precipitates free zones (PFZ's) were observed adjacent to the grain boundaries. However, (PFZ's) were more pronounced in furnace cooled specimens group than that in aircooled specimens group.Key words: cyclic stress strain curve, plastic strain rate, precipitate free zone, air-cooled, furnace cooled.

Development Of System With Transitory Steadiness Of A Bi-Machine Transmission System With Power System Stabilizers And Static Var CompensatorAbstract: In the previous studies the effect of Static Var Compensator (SVC) and Power System Stabilizers (PSS) has not been considered specially for various faults in a three phase system. For improvement in inductive and capacitive power flows Shunt Flexible AC Transmission System (FACTS) devices can be used and when they are placed in the center of transmission line of a electrical power transmission network. We made models with different FACTS devices and also varied their location for reducing fluctuations in voltage and improvement in transient stability. We have found that, shunt Static Var Compensator are best, so we have continued our research using shunt SVC. Again during our study we have found that if we slightly change the position of FACTS devices towards generator performance of the system improves but it eventually depends on load either local or of overall system. The work described here illustrates modeling of a simple transmission system containing two hydraulic power plants. A static var compensator (SVC) and power system stabilizers (PSS) are used to improve transient stability and power oscillation damping of the system. The power system illustrated in this thesis is quite simple. However, the phasor simulation method allows the user to simulate more complex power grids. We have used MATLAB for the study of the system.Key words: Var Compensator (SVC) and Power System Stabilizers (PSS), Thyristor Controlled Reactor (TCR), Three phase system. Reference [1] P.

Performance Analysis Of Energy Optimization Techniques In Wireless Sensor NetworksAbstract: Fast growth of wireless services in recent years is an indication that considerable value is placed on wireless networks. Wireless devices have most utility when they can be used anywhere at any time. One of the greatest challenges is limited energy supplies. Therefore, energy optimization is one of the most challenging problems in wireless networks. In recent years, Wireless Sensor Networks have gained growing attention from both the research community and actual users. As sensor nodes are generally battery-energized devices, so the network lifetime can be widespread to sensible times. Therefore, the crucial issue is to prolong the network lifetime. In this paper, two Energy Optimization Schemes Clustering and Direct Diffusion for Wireless Sensor Networks (WSN) has been compared on the basis of different parameters like scalability, energy efficiency and reliability etc. on the basis of this comparison we can use better Optimization technique according to the situation.Reference [1] I.F.

Comparative Analysis of Speed Control of DC Motor Using AI TechniqueAbstract: This paper presents a comparative study of various controllers for the speed control of DC motor. The Proportional Integral Derivative (PID) controller is one of the most common types of feedback controllers used in dynamic systems. This controller has been widely used in many different areas such as aerospace, process control, manufacturing, robotics, automation etc. As PID controllers require exact mathematical modelling, the performance of the system is questionable if there is parameter variation. Further two more controllers are proposed namely; Fuzzy Logic Controller and FOPID Controller. The performances of the three controllers are compared. Simulation results are presented and analysed for all the controllers. It is observed that Fuzzy Logic based controller gives better response than PID and FOPID controller for the speed control of dc motor.Key words: Proportional-Integral-Derivative controller, Fuzzy Logic controller, FOPID controller, DC motor speed control.

Design and Implementation of Pipelined FFT ProcessorAbstract: It is important to develop a highperformance FFT processor to meet the requirements of real time and low cost in many different systems. So a radix-2 pipelined FFT processor based on Field Programmable Gate Array (FPGA) for Wireless Local Area Networks (WLAN) is proposed. Unlike being stored in the traditional ROM, the twiddle factors in our pipelined FFT processor can be accessed directly. A novel simple address mapping scheme is also proposed. The FFT processor has two pipelines, one is in the execution of complex multiplication of the butterfly unit, and the other is between the RAM modules, which read input data, store temporary variables of butterfly unit and output the final results. Finally, the pipelined 64-point FFT processor can be completely implemented within only 67 clock cycles.Key words: FFT; FPGA; address mapping Reference [1] J. A. C.

| 197. | An Overview of Disarray in Active Suspension System
An Overview of Disarray in Active Suspension SystemAbstract: When designing a suspension system, the dual objectives are to minimize the Vertical forces transmitted to the passengers and to maximize the tire-to-road contact for handling and safety. Comfort ability of passenger is very much related to the vertical forces that transmitted from the car body. This objective can be achieved by minimizing the vertical car body acceleration. An excessive wheel travel will result in non-optimum attitude of tyre relative to the road that will cause poor handling and adhesion. Furthermore, to maintain good handling characteristic, the optimum tyre toroad contact must be maintained on four wheels. In conventional suspension system, these characteristics are conflicting and do not meet all conditions. So there are various investigations are going on for the study of improvement in active suspension over passive suspension system. In this paper overview of various works are done. This paper tries to give an idea about the previous researches & their finding about study of passive and active suspension system parameters by considering quarter car model.Key words: Active suspension system, control system, dynamics, passive suspension, vehicles.

A Comparative Study on Methods of Curing Concrete –Influence of HumidityAbstract: Efficient uninterrupted curing is the key to quality concrete. Proper curing of concrete is crucial to obtain design strength and maximum durability. The curing period depends on the required properties of concrete, the purpose for which it is to be used, and the surrounding atmosphere namely temperature and relative humidity. Curing is designed primarily to keep the concrete moist, by preventing the loss of moisture from the concrete during the period in which it is gaining strength. Curing may be applied in a number of ways and the most appropriate means of curing may be dictated by the site or the construction method. The present paper is directed to evaluate effectiveness of different curing methods and study the influence of climate on the strength properties of concrete.Key words: Curing of Reference 1.

Extreme And Distribution Data Of Drainage System In The City Of AmbonAbstract: Climate change has been a significant environmental issue during this century. Various studies have been conducted in order to identify the causes of climate change. To avoid the harmful effects of extreme rainfall events and climate, it is necessary to give special attention to the extreme values, given the inability of human beings to avoid or escape from disaster that is caused by phenomena of precipitation and climate (temperature). One theory that specifically addresses extreme events is EVT (Extreme Value Theory). The purpose of this study is to provide an overview of extreme, distribution and modeling values as well as diagnostics model which is modeled with GEV distribution. The family of GEV distribution has three sub-families namely Gumbel, Fréchet and Weibull. This distribution is characterized by three parameters: the location, scale, and shape parameter. From the data distribution test with error rate (α) of 0.05, it gives a result that the tested distribution fits with GEV and Normal distribution. For the suitability distribution, in addition to specific inferential test, it can also be tested using the P-P plot and Q-Q plot. While empirical CDF graph is used to evaluate the fit of the data compared to the data distribution of the cumulative distribution of samples in which both probability values gives a similar profile at both levels axis. Based on return level of 100 years from the analysis of the maximum temperature, it increases only 10.66% or the xk value = 29.367 °C which means that in the period (return period) of 100 years, temperatures in the study area of Ambon will surpass 29.367 °C. Therefore, it is certain that the temperature changes in the study area are not too significant and have extreme phenomenon compared to the one with the maximum rainfall.Key words: Climate change, GEV distribution, return level Reference 1.

Productivity Analysis of Reactive Routing Protocol for IEEE 802.11e standard using QualNet SimulatorAbstract: The continuous improvement of sensor skill and wireless communication is encouraging wireless sensor networking. The IEEE 802.11e Medium Access Control (MAC) is upcoming standard of IEEE to support Quality of Service (QoS). The IEEE 802.11e MAC enhances the basic 802.11 MAC to provide quality-of-service support for audio and video streams. The 802.11e MAC defines a new Hybrid Coordination Function (HCF), which provides an Enhanced Distributed Channel Access (EDCA) method and an HCF Controlled Channel Access (HCCA) method. Some recent work can prove that 802.11e Hybrid Coordinate Function (HCF) can improve significantly the quality of service (QoS) in 802.11 networks. The HCF scheduling algorithm is only for Constant Bit Rate (CBR) characteristics. In this paper we investigate the performance of 802.11e through computer simulations. We design a scenario and analysis the performance metrics of Ad-hoc On-demand Distance Vector (AODV) and Dynamic Source Routing (DSR) protocols for IEEE 802.11e standards. Performance metrics like throughput, average end-to-end delay, average jitter, energy consumed in transmit and received modes, which is carried out using QualNet simulator.Key words: AODV, DSR, Average End-to-end delay, IEEE 802.11e standard, QualNet Reference [1] Mayank Mishra and Anirudha Sahoo.

Effects of Hall Current on MHD Free and Forced Convection flow of Newtonian fluid through a Porous medium in an Infinite vertical plate in presence of Thermal radiation heat transfer and surface temperature oscillationAbstract: In this paper, we study the steady and unsteady magneto hydro dynamic (MHD) viscous, incompressible free and forced convective flow of an electrically conducting Newtonian fluid through a porous medium in the presence of appreciable thermal radiation heat transfer and surface temperature oscillation taking hall current into account. The fluid is assumed to be optically-thin and magnetic Reynolds number small enough to neglect induced hydro magnetic effects. Secondary (cross-flow) effects are incorporated. The governing equations are solved analytically using complex variables. Detailed computations of the influence of governing parameters on the unsteady mean flow velocity (u1) and unsteady mean cross flow velocity (w1), the plate shear stresses for the unsteady main and the secondary flow and also temperature gradients due to the unsteady main flow and the unsteady cross flow, are presented graphically and tabulated. The closed-form solutions reveal that the shear stress component due to a steady mean flow experiences a non-periodic oscillation which varies as a function of the Hartmann number (M 2 ) and radiation parameter (K1). However the shear stress components due to main and cross flows for an unsteady mean flow are subjected to periodic oscillation which depends on Hartmann number, inverse Darcy parameter, radiation parameter but also on the Prandtl number and frequency of oscillation. Applications of the model include fundamental magneto-fluid dynamics, MHD energy systems and magnetometallurgical processing for aircraft materials.Key words: steady and unsteady flows, thermal radiation heat transfer, hall current effects, free and forced convective flows, surface temperature oscillation and porous medium.

Survey of Security in Service Oriented ArchitectureAbstract: Service Oriented Architecture (SOA) is a driving force behind all present and evolving techniques of data exchange and resource sharing over the network. This helps in adapting to the changing market needs efficiently and effectively. Inherent characteristics of SOA framework have nurtured agility and flexibility in distributed computing environment but also have posed high security challenges.

Experimental Investigation on Performance Improvement of Biogas PlantAbstract: Biogas is a sustainable fuel that stands out from other biofuels because of the major environmental and socio-economic benefits that can be achieved. This opens up enormous potential for sustainable economic growth and will also improve our energy security. An attempt has been made to find the different ways to improve the overall performance of biogas plant. The present work comprise of improving the biogas yield in terms of quality and quantity. Since it is a well known fact that temperature improves the performance of biogas plant, experimentation is carried out to modify the existing mild steel dome based biogas plant by transparent type fibre dome to capture the green house effect. Modifications are carried out in one of the plant and the second plant is kept as a reference. So far these two biogas plants were studied for composition, yield, temperature effect; pH value of the end digestate.Key words: ENERGY SECURITY, TRANSPARENT FIBRE DOME, MILD STEEL DOME, TEMPERATURE, PH.

Combined Economic Load And Emission Dispatch Evalution Using Bat AlgorithmAbstract: This paper presents an application of BAT algorithm for multi-objective optimization problem in power system. Considering the environmental impacts that grow from the emissions produced by fossil-fuelled power plant, the economic dispatch that minimizes only the total fuel cost can no longer be considered as single objective. Application of BAT algorithm in this paper is based on mathematical modelling to solve economic, emission and combined economic and emissions dispatch problems by a single equivalent objective function. BAT algorithm has been applied to two realistic systems at different load condition. Results obtained with proposed method are compared with other techniques presented in literature. BAT algorithm is easy to implement and much superior to other algorithms in terms of accuracy and efficiency.Key words: Economic dispatch; BAT algorithm; Artificial Bee Colony algorithm; Combined economic and emission dispatch; Mathematical modelling.

Efficiency Analysis of Hydraulic Power Steering SystemAbstract: Hydraulic assisted power steering system is a high bandwidth servo with stringent performance requirements on accuracy, reliability, and cost. Design of such a system can be best achieved by using a validated and user friendly computer simulation program. Hydraulic integrated power steering ( HIPS ) program has been developed using basic concepts from science and engineering. HIPS provides a design and test environment for the integrated steering and suspension system subjected to disturbance forces, which may be induced by pump flow oscillations and tire loads. Two real-world automotive hydraulic steering systems are simulated with HIPS. The simulation results agree closely with the dynamometer test results. The application of HIPS for design optimization is also demonstrated.Reference [1] CSSL-IV User Guide and Reference Manual, Simulation Services, Chatsworth, CA [2] Sahinkaya, Y., A Novel Steering Vibration Stabilizer, 1996 SAE International Congress and Exposition, February, Detroit, MI [3] Bosch: Kraftfahrtechnisches Taschenbuch, Publisher: Robert Bosch GmbH,Stuttgart, Vieweg Verlag, 23rd printing, Wiesbaden, Germany, 1999 [4] Brander, M.:Modellerstellung und Simulation einer wirkungsgradoptimierten hydraulischen Fahrzeuglenkung.

STEGO-WATERMARKAbstract: The evolution of the Internet helps the transmission of digital multi- media content such as text, audio, images, and video easier. Digital media can be accessed or distributed through the network. As the communication over internet is easier and convenient, the security becomes main concern. One of the approaches for secured transmission is Steganography in which secrete message is hidden behind the image. For authenticity, digital watermarking is a technique which embeds a digital signature or digital watermark that asserts the ownership or intellectual property rights of the owner .In this a hybrid approach is used, in which watermarking and Steganography techniques have been combined, which exploits the advantages of both techniques results in more robustness against different types of attacks.Key words: Robustness, Steganography, Watermarking.

AN ENHANCED DSR PROTOCOL USING PATH RANKING TECHNIQUEAbstract: Mobile Adhoc networks are infra structure-less and are categorized by multi-hop wireless connectivity and dynamic changing network topology. They are self organized networks without dependency on any fixed infrastructure. Application area of MANET is varied, ranging from small, static networks to large scale highly mobile and highly dynamic networks. Routing is an important issue in wireless adhoc networks. Routing protocols plays a very important role because MANET use dynamic changing network topology. Most famous categories are Proactive, Reactive and Hybrid. Proactive routing protocols setup route based on continuous control traffic information. All routes and maintained all the times. On the other hand Reactive routing protocols does not take any initiative for finding routes. It establishes routes 'on demand' basis. Hybrid protocol have the advantages of both proactive and reactive protocol. In this paper, an attempt has been made to compare performance of ZRP (hybrid), DSDV (Proactive) and reactive (DSR and modified DSR) on the basis of their performance in MANETs using NS2 simulator. A comparative study on reactive and proactive has been done by some modification that how DSR can be modified for its performance enhancement from average to something extra to make MANETs more reliable. To achieve this goal DSR is modified by using route ranking technique in order to load balancing, to avoid congestion and lower packet delivery.Key words: Proactive protocol, Reactive protocol, Hybrid protocol, NS2, Performance evaluation Reference [1] Chai-Keong Toh.

Dynamic Mechanical Properties of Copper-ABS Composites for FDM FeedstockAbstract: This paper presents an investigation of dynamic mechanical properties of a copper-ABS composite material for possible fused deposition modeling (FDM) feedstock. The material consists of copper powder filled in an acrylonitrile butadiene styrene (ABS). The detailed formulations of compounding ratio by volume percentage (vol. %) with various combinations of the new polymer matrix composite (PMC) are investigated experimentally. Based on the result obtained, it was found that, increment by vol. % of copper filler ABS affected the storage modules (E') and tan δ results. The storage modulus and tangent delta increased proportionally with increment of copper filled ABS. It can be observed that, the storage modulus and tangent delta are dependent on the copper filled ABS in the PMC material.Key words: Polymer Matrix Composites, Dynamic Mechanical Properties, Storage Modulus, Loss Modulus, Tan δ, Fused Deposition Modelling Reference 1.

An Efficient Algorithm For Deblurring A Natural ImageAbstract: Blurred image has always been a bottleneck for investigating agencies. Deblurring from a single image has been an ill-posed and challenging problem due to the large number of unknowns in the estimation process. The unknowns are the type of blur, the extent of blur and the noise, which degrade the image further. There does not exist any efficient algorithm that can deblur any given image. This paper attempts to deblur blindly a given natural image with an assumption of uniform blur throughout the image. The algorithm uses the Variation Bayesian approach for optimizing the posterior probability and deriving the most probable Point Spread Function (PSF). Once the PSF is estimated, a modified Lucy Richardson algorithm is used to do the deconvolution operation and to get the deblurred image. The algorithm is found to be very effective for natural images and the results are quantified using the Cumulative Probability of Blur Detection (CPBD) valuesReference [1] Wikipedia, Point spread function --- Wikipedia [2] R.

Secure communication is a key for any wireless network . Like all other networks, cognitive radios are susceptible to various kinds of attacks like DOS attack , PUE attack , tunnel attack and jamming attack . While performing these attacks nodes in the network becomes selfish and start maximizing their own spectrum usage and they prevent other users from communicating in the same network . In this paper an algorithm is generated which can detect selfish nodes in a network .

Control of Two Wheeled Inverted Pendulum Using Silding Mode TechniqueAbstract: In this paper, a controller via sliding mode control is applied to a two-wheeled inverted pendulum, which is an inverted pendulum on a mobile cart carrying two coaxial wheels. The controller is developed based upon a class of nonlinear systems whose nonlinear part of the modeling can be linearly parameterized. The tracking errors are defined, then the sliding surface is chosen in an explicit form using Ackermann's formula to guarantee that the tracking error converge to zero asymptotically. The control law is extracted from the reachability condition of the sliding surface. In addition, the overall control system is developed. The simulation and experimental results on a two-wheel mobile inverted pendulum are provided to show the effectiveness of the proposed controller.Key words: Sliding mode controller, two wheeled inverted pendulum.

Study of Self Compacting Concrete Using Brick Dust and Marble PowderAbstract: In recent years, Self Compacting Concrete (SCC) has gained a wide use for placement in congested reinforcement concrete structures where casting conditions are difficult and in high rise buildings where pump ability properties are required. For such applications the fresh concrete must possess high fluidity and good cohesiveness. The use of fine materials such as brick dust, marble powder and viscosity modifying agent can ensure the required concrete properties. In this experimental work attempt has been made to replace fine aggregate with brick dust and marble powder. Both brick kiln dust and marble powder are waste materials and are dumped as waste, causing land scarcity and environmental pollution. Using these types of waste material for concrete is a bigger step towards sustainable infrastructure developmentReference 1.

Segmenting: A New-Fangled Advance to Isolation Conserving Facts DistributingAbstract: Re-identification is a major privacy threat to public datasets containing individual records. Many privacy protection al- gorithms rely on generalization and suppression of "quasi- identifier" attributes such as ZIP code and birthdate. Several anonymization techniques, such as generalization and bucketization, have been designed for privacy preserving micro data publishing. Recent work has shown that general- ization loses considerable amount of information, especially for high-dimensional data.

The research shows that buy back contract can coordinate the supply chain and fairness preference will not affect the coordination of buy back contract. Moreover, the retailer's optimal order quantity will not change as buy back contract concerning fairness preference, but the retailer's optimal order quantity will be increase as the cost increase. The most important finding in this paper is that even when the supplier don't know the retailer's degree of fairness preference, he can also design a wholesale price and a buyback price to achieve the best profits or utility.Key words: Nash bargaining; Newsvendor model; Buy back contract; Fairness preference; Supply chain coordination Reference [1] Gilbert H M.

Data leakage analysis on cloud computingAbstract: Cloud describes the use of a collection of services, applications, information, and infrastructure. It is like a pool of resources and services available in a pay as- you-go manner. Services like computation, network, and information storage. This paper mainly focus on the major security concerns about cloud computing. The major areas of focus are: - Information Protection, Virtual Desktop Security, Network Security, and Virtual Security. In today's business world, many organizations use Information Systems to manage their sensitive and business critical information. The need to protect such a key component of the organization cannot be over emphasized. Data Loss/Leakage Prevention has been found to be one of the effective ways of preventing Data Loss. DLP solutions detect and prevent unauthorized attempts to copy or send sensitive data, both intentionally or/and unintentionally, without authorization, by people who are authorized to access the sensitive information. DLP is designed to detect potential data breach incidents in timely manner and this happens by monitoring data.Key words: Data leakage analysis in cloud computing; Data leakage prevention in cloud computing; Checking sensitivity of data; Data security in cloud Reference [1] Ma Jun, Wang Zhiying, Ren Jiangchun, Wu Jiangjiang, Cheng Yong and Mei Songzhu," The Application of Chinese Wall Policy in Data Leakage Prevention" in International Conference on Communication Systems and Network Technologies,2012.

Analysis of Partial Discharge using Phase-Resolved (n-q) Statistical TechniquesAbstract: Partial discharge (PD) patterns are an important tool for the diagnosis of high voltage (HV) insulation systems. Human experts can discover possible insulation defects in various representations of the PD data. One of the most widely used representations is phase-resolved PD (PRPD) patterns. In order to ensure reliable operation of HV equipment, it is vital to relate the observable statistical characteristics of PDs to the properties of the defect and ultimately to determine the type of the defect. In this work, we have obtained and analyzed phase-resolved discharge patterns using parameters such as mean, standard deviation, variance, skewness and kurtosis.Key words: Partial Discharge, Phase-resolved, Statistical parameters Reference [1] Partial Discharge Measurements, IEC Publication 270, 1981.

If a line of Sight exists between the transmitter and receiver then Rician fading is modelled and in the absence of a line of Sight path Rayleigh fading can be modelled. The multipath intensity profile of a mobile radio channel depends critically on the type of terrain. The Performance comparison of the Rayleigh and Rician Fading channels in Differential Phase Shift Keying modulation using Simulink tool is dealt in this paper.Key words: Fading, Rayleigh, Rician, DPSK.

A Novel Approach for Increasing Channel Navigation in IPTV Based on User's Channel Selection Interests'Abstract: With the recent advances in the video technologies as well as the widespread adoption of broadband internet services, there has been a significant increase in the interest & demand for multimedia streaming services & the IPTV (Internet Protocol Television) has become one of the major internet applications. The IPTV has several unique features when compared to traditional broadcasting services such as terrestrial, cable, and satellite broadcasting services in some aspects. Unlike satellite or terrestrial broadcasting Televisions that support limited number of channels due to fixed radio frequency bandwidth , the IPTV can accommodate more than hundreds of channels by using the IP (Internet Protocol) network. The increased No. of channels allows IPTV users to enjoy a variety of contents, but the task of finding one's favourite contents becomes even more difficult. To relieve this problem, our paper presents a popular channel concentration scheme for efficient channel navigation in IPTV. Based on the property that TV channel selections concentrate on several frequently selected channels, the proposed scheme reorganizes channel sequences by clustering popular channels. Specifically, channels are rearranged in a frequency interleaved way to minimize the seek distance. Simulation studies show that the proposed scheme reduces the seek time of IPTV channel navigation significantly when up-down channel selection interfaces are used.Key words: IPTV, channel navigation, channel selector, channel seek time, watching behavior.

It represents a situation that is a true paradigm shift from the typical way in which technological advancements become main stream in high-technology semiconductor manufacturing processes. Colloidal nano-abrasives with different particle sizes are required for slurries in different CMP processes. Colloidal silica is used as polishing slurry for producing reflecting surfaces for mirrors, lenses and the planarization of computer chips. Industrial use of colloidal silica's is growing steadily in both traditional areas and ever-increasing numbers of novel areas. Colloidal silica's are found in fields as diverse as catalysis, metallurgy, electronics, glass, ceramics, paper and pulp technology, optics, elastomers, food, health care and industrial chromatography, polishing sophisticated microcircuit parts to outer space and play vital role in the safe reentry of space vehicles and the development of Western for that matter, world civilization.

A new approach to solve n-queens problem based on seriesAbstract: The N-queens problem is a popular classic puzzle where numbers of queen were to be placed on an n x n matrix such that no queen can attack any other queen. The Branching Factor grows in a roughly linear way, which is an important consideration for the researchers. However, many researchers have cited the issues with help of artificial intelligence search patterns say DFS, BFS and backtracking algorithms. The proposed algorithm is able to compute one unique solution in polynomial time when chess board size is greater than 7. This algorithm is based on 8 different series. For each series a different approach is taken to place the queen on a given chess board.Key words: Analyzer, Move, Rule, Partz Reference [1] V. Kesri, Va. Kesri and P. Ku. Pattnaik.

Evaluation of Effective Factors on Auditing Fees Using Fuzzy Regression Compared with Linear RegressionAbstract: Fuzzy regression can be used to evaluate the relationships between the variants when their information is indefinite. As one of the biggest challenges of auditing firms is to determine the auditing fees, evaluating the factors effective on their remunerations is of high importance. Here we use fuzzy regression in evaluating the factors effective on auditing fee, when it is indefinite, and eventually their final results are compared with the regression of the least squares. The final results of this research show a meaningful relationship between the firm's size (scale), tenure (ownership) and consultancy services with the auditing fee.Key words: auditing fee, fuzzy regression, firm's size, tenure, consultancy services.

An Adaptive MT-BGP Traffic Engineering Based on Virtual Routing TopologiesAbstract: Internet is not a single network. The Internet is a collection of networks, each controlled by different administrations. Traffic engineering is an important mechanism for Internet network providers seeking to optimize network performance and traffic delivery. Routing optimization plays a key role in traffic engineering, finding efficient routes so as to achieve the desired network performance. BGP is the de facto protocol used for inter-autonomous system routing in the Internet. BGP has been proven to be secure, efficient, scalable, and robust. In proposed introduced AMPLE – an efficient traffic engineering and management system that performs adaptive traffic control by using multiple virtualized routing topologies in MT-BGP. The proposed system contains three complementary components: offline link weight optimization that takes as input the physical network topology and tries to produce maximum routing path diversity across multiple virtual routing topologies for long term operation through the optimized setting of link weights in BGP (Border Gateway Protocol) with admission traffic control algorithm. In our proposal, AMPLE (Adaptive Multi-toPoLogy traffic Engineering), a holistic system based on virtualized BGP routing topologies for dynamic traffic engineering. This paper also concentrates creates new path with help of ADC algorithm. This scheme allows a network to operate in the region of low delay, no packet loss and high throughput.Key words: Admission control algorithm, ATC, BGP, OLWO, Reference [1] S.

Review: PERFORMANCE EVALUATION OF CHANNEL ESTIMATION IN MIMO OFDMAbstract: A multiple-input multiple-output (MIMO) communication system combined with the orthogonal frequency division multiplexing (OFDM) modulation technique can achieve reliable high data rate transmission high data rate transmission over broadband wireless channels. The data rate and spectrum efficiency of wireless mobile communications have been significantly improved over the last decade or so. Recently, the advanced systems such as 3GPP LTE and terrestrial digital TV broadcasting have been sophisticatedly developed using OFDM and CDMA technologyChannel state information for both single-input single-output (SISO) and MIMO systems is investigated in this paper. The estimation of channel at pilot frequencies with conventional Least Square (LS) and Minimum Mean Square (MMSE) estimation algorithms is carried out through Matlab simulation. The performance of MIMO OFDM and SISO OFDM are evaluated on the basis of Bit Error Rate (BER) and Mean Square Error (MSE) level. Further enhancement of performance can be achieved through maximum diversity Space Time Block Coding (STBC) and Maximum Likelihood Detection at transmission and reception ends respectively. MMSE estimation has been shown to perform much better than LS but is more complex than LS for the MIMO system using pilot carriers.Key words: Channel Estimation, MIMO-OFDM, Pilot carriers, Diversity, Spatial Multiplexing, Space time coding Reference [1] Ramjee Prasad, "OFDM for wireless communications systems" Artech House, Inc.

Thermal Analysis of Piston for the Influence on Secondary motionAbstract: The gas force due to the combustion in the cylinder of an IC engine will cause the piston to move with primary motion and secondary motion. The primary motion of the piston from TDC to BDC is linear in nature. This motion is desired for translation of motion of engine components. Secondary motion is due to the transverse motion of the piston while piston moving from TDC to BDC and vice-versa. The secondary motion of the piston is considered as the main source for the piston slap, which in turn causes the impact on the cylinder walls resulting in engine vibration and noise. In the present study, an effort is made to understand the effect of the thermal load, generated by the combustion of fuel inside the cylinder, on the piston deformation and thermal stresses induced in piston. This deformation of the piston inside the cylinder causes the gap between the cylinder and piston to vary and also the piston to move transversely along with impact forces.Key words: Deformation, FEA, Piston, Secondary motion, Simulation Reference [1] O.S.

EMBEDDED SOFTWARE DESIGN & IMPLEMENTATION FOR PLATFORM STABILIZATION USING MEMSAbstract: Platform stabilization is more important in most of the large scale applications like the oil well and nuclear product based processing machines and systems. So stabilization of that machinery is more important, failing to do so may cause a major damage to the society and which may even lead to an accident. Hence to avoid those kinds of accidents and damage, manual monitoring of those large systems and making necessary changes is practically impossible. This can be fully automated using the MEMS technology which will be more accurate and reliable in stabilizing the platform thereby making the whole system safe. Outcome of the project will be a cost effective method of stabilizing a platform and making the needful changes so that the platform or any system is stable.

Analysis Of Anti Vibration Mounts For Vibration Isolation In Diesel Engine Generator SetAbstract: Engine vibrations have been one of the major problems for the engine manufacturers in the world. The engine excitation forces, arising from the gas pressure and unbalance forces are the sources of vibrations.Anti Vibration Mounts(AVMs) are the structures used to absorb the vibrations and dampen the harm causing forces. Mount result in a system which is modeled as mass/spring/damper. The elastomer is under vertical and shear load at the same time. The engine is bolted freely on mount which dampens the vibrations going to the base frame/canopy. The validation of their characteristics is implemented in a single degree of freedom system with response to frequency domain. The engine is mounted freely on the AVM's which helps to dampen the vibrations to base frame. Frequency Response Function(FRF) is derived for analysis, analytically and Computer Aided Engineering(CAE).Key words: Anti-Vibration Mounts (AVMs), CAE,Elastomers,Engine,FRF,Vibrations.

Numerical Analysis On The Performance Characteristics Of The Centrifugal PumpAbstract: The research is based on the performance of the centrifugal pump having the backward, radial and forward bladed type of impeller. The impeller is modeled using Creo Parametric 1.0 having 70 and 80 degree outlet blade angle for the backward type and outlet blade angle 90 for radial and 100 degree for forward type impeller respectively. Numerical simulation is carried out using ANSYS CFX and standard k- turbulence model is adopted for the analysis purpose. Cavitation is clearly predicted in the form of water vapor formation inside the centrifugal pump. The performance of the pump is affected by the cavitation and hence cavitation number (σc) is a measure of the cavitation phenomenon for the centrifugal pump, it is determined by analytical calculations. From the numerical results it has been found that the pump working on low head gives the best performance when it is operated with the backward bladed type impeller.Key words: ANSYS CFX, Cavitation, Cavitation number, Centrifugal pump, numerical simulation, Turbulence Model k- Є.

Experimental Behavioural Study Of Ductile Cast Iron Microstructure And Its Mechanical PropertiesAbstract: Ductile cast Iron also referred to as nodular iron or spheroidal graphite iron. The Ductile cast iron contains graphite it is in the form of discrete nodules or spheroids. This paper deals with some factors influencing microstructure and mechanical properties of ductile cast iron (DCI). Ductile cast iron have been used for a wide variety of application in automotive, rail and heavy engineering industry because of its excellent mechanical properties such as high strength with good ductility, good wear resistance and good fatigue properties. The properties of ductile cast iron are dependent on both chemistry and heat treatment. Nodular cast iron are primarily heat treated to create matrix micro structure and associated mechanical properties not readily obtain in the as-cast condition. Final structure and properties of DCI are obtained by exactly controlled process of heat treatment. Experiments are conducted on 600/3 and 500/7 grades of ductile cast iron and following observations are made to know the properties of metal. Results of the experiment shows that it dependence of temperature and various matrixes can be obtained (i.e. mixture of graphite, ferrite and pearlite). Different quenching medias are selected to check the behaviour of the materials. Quenching medias like vegetable oil, mineral oil and water are used for this experimental analysis. After heat treatment the tensile strength, hardness, elongation and yield stress of the specimens are obtained with respect to different quenching medias.Key words: DCI (Ductile cast iron), heat treatment process, quenching medias.

Survey of Harmonics Measurements in Electrical Distribution System of a Technical InstitutionAbstract: Growing use of non-linear loads give rise to power pollution in the three-phase four-wire distribution system. This has already become an alarming situation in an engineering institute where quality power is an essential requirement.To ensures quality power it is necessary that a harmonic study is carried out to identify the details of pollution that is polluting sources, the parameters or quantities they pollute in each instance. The paper includes a harmonic survey in the Electrical machine lab of National Institute of Technology, Agartala where various non-linear devices are used everyday. The level and type of the harmonics present in the system are identified. According to the measurement and analysis, the effect of most prominent harmonics are found out that could cause problem in the power quality. The harmonic survey is performed to improve the power quality.Key words: Distribution system, harmonics, harmonic survey non-linear loads, power quality, power quality analyzer, total harmonic voltage distortion, total harmonic current distortion,three-phase, technical institution.

Extended Adaptive Pixel Pair MatchingAbstract: Steganography is a method of hiding secret messages into a cover-media such that an unintended observer will not be aware of the existence of the hidden messages. The carrier of steganography can be various kinds of digital media such as image, audio, and video, etc. Digital images are widely transmitted over the Internet; therefore, they often serve as a carrier for covert communication. A good data-hiding method should be capable of evading visual and statistical detection while providing an adjustable payload. In [1], authors proposed Adaptive Pixel Pair Matching (APPM). The basic idea of Pixel Pair Matching (PPM) is to use the values of pixel pair as a reference coordinate, and search a coordinate in the neighborhood set of this pixel pair according to a given message digit. The pixel pair is then replaced by the searched coordinate to conceal the digit. APPM allows users to select digits in any notational system for data embedding, and thus achieves a better image quality. APPM not only resolves the low-payload problem in EMD, but also offers smaller MSE compared with OPAP and DE. Moreover, because APPM produces no artifacts in stego images and the steganalysis results are similar to those of the cover images, it offers a secure communication under adjustable embedding capacity. This paper proposes an extension to APPM, for high definition color images. EAPPM provides high data capacity without compromising on performance and security of APPM.Key words: Steganography, Pixel Pair Matching (PPM), Diamond Encoding (DE), Least Significant Bit (LSB) Reference [1] Wien Hong and Tung-Shou Chen, "A Novel Data Embedding Method Using Adaptive Pixel Pair Matching", IEEE TRANSACTIONS ON INFORMATION FORENSICS AND SECURITY, VOL. 7, NO. 1, FEBRUARY 2012.

Heat Transfer Augmentation in Concentric Tube Heat Exchanger Using Twisted TapesAbstract: The present paper deals with the results of an experimental investigation carried out to find the overall performance of suitably designed concentric tube heat exchanger with passive heat transfer augmentation technique. The desired augmentation is attained with the help of twisted tape inserts. In addition to this, the performance of twisted tapes with holes and with baffle plates is carried out to find the suitable design for the heat transfer augmentation. The effect of twisted tape inserts on effectiveness of heat exchanger is analyzed at different mass flow rates. It is found that full length twisted tapes produce a better performance as compared to other designs tested.Key words: Effectiveness, Heat exchangers, Inserts, Twisted Tapes Reference [1] S.K.Saha A.Dutta " Thermo hydraulic study of laminar swirl flow through a circular tube fitted with twisted tapes" Trans.

Comperative Study Of S.M.R.F. Building Over O.M.R.F. Building With Seismic And Wind EffectAbstract: Seismic evaluation will provide a general idea about the building performance during an earthquake. The criteria of evaluation of building will depend on materials, strength and ductility of structural components and detailing of reinforcement. In this report Special Moment Resisting Frame (Ductile Detailing) and Ordinary Moment Resisting Frame are considering as structural frame and Comparison are made for seismic load. Detailing of reinforcement and design in case of Ordinary Moment-Resisting Frame are made by using IS 456 Provision's, while in case of Special Moment-Resisting Frame detailing of reinforcement and design are made by using IS 456:2000, as well as detailing done by IS 13920:1993. Hence OMRF Structure are to be designed for relatively very higher equivalent forces that of SMRF Structures. This helps in to why use of IS 1390:1993 is very effective for detailing the structure, hence it is economical. Thus the performance of SMRF structure in Earthquake is quiet good as compare to OMRF structure.Reference [1] Kaur S., Singh B., Singh S P, Lal R "Analytical Investigation on the Strength and Deformation Characteristics of Reinforced Concrete Beams - IE(I) Journal- CV Volume 87, February 2007" [2] Haselton1 C.

Seismic Evaluation and Retrofitting of RC Building by Using Energy Dissipating DevicesAbstract: The Buildings, which appeared to be strong enough, may crumble like houses of cards during earthquake and deficiencies may be exposed. Experience gain from the recent earthquake of Bhuj, 2001 demonstrates that the most of buildings collapsed were found deficient to meet out the requirements of the present day codes. In last decade, four devastating earthquakes of world have been occurred in India, and low to mild intensities earthquakes are shaking our land frequently. It has raised the questions about the adequacy of framed structures to resist strong motions, since many buildings suffered great damage or collapsed. Under such circumstances, seismic qualification of existing buildings has become extremely important. Seismic qualification eventually leads to retrofitting of the deficient structuresReference [1] V.S.R. Pavan Kumar.Rayaprolu, P.

Study Of Switching And Analysis Behaviour Between Fault And Magnetizing Inrush Current In TransformerAbstract: A new scheme to classify between internal fault current and inrush current of power transformer is presented in this paper conventionally this paper presents a novel technique for three phase transformer protection, which the method effectively identify Magnetizing inrush currents from internal fault currents. This technique employs symmetrical components. When transformer is switched, inrush current happens. This current has some Features, which it is enough for identify itself. In this paper, by extract these features, a new criterion is proposed to discriminate inrush currents from internal faults in power transformers. In faulty time such as switching or short circuit, the value of negative sequence for differential current is different from positive sequence value. Helping this feature, new criterion is introduced. Simulations show this criterion works properly in over-flux and CT saturation condition too. The simulated results presented clearly, the proposed algorithm can accurately discriminate between an internal fault and a magnetizing inrush current in power transformer protection in all cases.Key words: inrush current, internal fault, Symmetrical component, transformer protection, type of Faults, Transformer energizing, PSCAD Reference [1] F.

Plasticity and Compaction Characteristics of Soil Mixtures Comprising Of Expansive Soils and A Cohesive Non-Swelling SoilAbstract: In Soil is naturally occurring material that is used for the construction of structures except the surface layers of pavements. This naturally occurring soil may not suit the design requirements of ongoing project. So, soil is to be prepared to meet the requirements called soil stabilization. Stabilization is the process of blending of different soils or mixing of additives to a soil to improve characteristics of the soil such as gradation, strength, durability, workability, plasticity etc. and thus making it more stable. It is required when the soil available for construction is not suitable for the intended purpose. The present paper emphasized on investigation of soil mixtures comprising of three expansive soils mixed with a cohesive non-swelling soil pertaining to plasticity characteristics, compaction characteristics, Soil-mixtures are prepared with expansive soils adding different percentages of cohesive non-swelling soil varying from 15% to 35% by weight of expansive soil with 5% interval.Key words: soil mixtures, soil stabilization, Liquid Limit, Plastic Limit, Light Compaction Test Reference [1] Acosta, H.A., Edil, T.B., Benson, C.H.
