ABSTRACT : A series of hexagonal ferrite samples with the composition of Ba1-xGdxFe12O19 (x = 0.0, 0.10, 0.20 and 0.30) have been prepared by employing the ceramic technique. The structural properties of the calcined samples were studied using X-ray diffraction (XRD), SEM technique and FTIR spectrum. The samples were sintered at 1150°C for 8 hours. The X-ray diffraction patterns shows that the prepared samples have a single phase and the effect of composition on the unit cell parameters, density and porosity has been studied. Spectrum of Ba1-xGdxFe12O19 ferrites have been studied. The lattice parameters 'c' and 'a' was found to increase by increasing Gd-content whereas the X-ray density decreases and porosity increase by increasing Gd-content. Microstructural analysis by scanning electron microscopy (SEM) suggest that the compound have small grains distributed uniformly and non-uniformly on the surface of the sample and also shows that the grain size has been decreases by increasing the Gd-content in the composition Ba1-xGdxFe12O19.

ABSTRACT : Encryption is mainly used to transmit the data over networks. There are so many techniques introduced which are used to protect the confidential image data from any unauthorized access. Multimedia data contains different types of data that includes text, audio, video, graphic, images with the increasing use of multimedia data over internet, here comes a demand of secure multimedia data. Most of the encryption algorithm available is generally used for text data and not suitable for multimedia data. In this dissertation a new symmetric image encryption scheme based on correlation pattern. The idea of this system is to find the pixel interdependency correlation between dependent pixel and independent pixel of image and get grayscale images. Then create the slots of bit and generate the pattern and apply the symmetric key algorithm are use for encryption. Proposed method is secure against the entropy, brute-force, statistical, and differential attacks from a strict cryptographic viewpoint. This cryptosystem has a very powerful diffusion mechanism(a small change in the plain text makes a great change in the cipher image) thus the proposed cryptosystem can be used in different applications, depending on the core algorithm used, Advantage of this approach, is that it reproduce the original image with no loss of information for the encryption and decryption process.

ABSTRACT : With today's increasingly competitive economy, many organizations have initiated customer relationship management (CRM) projects to improve customer satisfaction, revenue growth and employee productivity gains. However, only a few successful CRM implementations have successfully completed. For organizations today, competitive advantage comes not only from developing and selling the most innovative product at the best price, but also from delivering the best sales and customer-service experience. Customerfacing processes often represent significant inefficiencies that can be remedied by Six Sigma CRM processes. Thus, we can say that Six Sigma CRM improves understanding of customer behavior, allowing you to acquire new customers and build loyalty among both existing and acquired customers. Six Sigma CRM is a way of continuously increasing customer satisfaction and profit that goes beyond reducing defects and emphasizes businessprocess improvement in general. This customer-centered Six Sigma CRM approach can help your organization: Increase sales and improve win rates Create top-line growth by developing and delivering products that customers value Improve service, reduce response time and improve customer satisfaction Reduce costs and improve quality by 20%- 50% across the board, including an 85% reduction in sales-approval and proposal turnaround times, 100% sales-force empowerment in the sales process and 250% improvement in service-request closure times. In this paper we propose a strategy to integrate six sigma DMAIC methodologies with the CRM implementation.

ABSTRACT : In this Paper a new secret visual cryptography scheme for color images based on the cyclic shifting pixels with cheater identification. Firstly, a chromatic image is decomposed into three monochromatic images using HSV color model. Secondly, these three images are transformed into binary images by using cyclic shifting pixels technique. Finally, the traditional binary secret sharing scheme is used to get the sharing images. This Scheme provides a more efficient way to hide natural images in different shares. Furthermore, the size of the shares does not vary when the number of colors appearing in the secret image differs. And also identify the cheater of shares.

ABSTRACT : Biodiesel fuel can be made from new or used vegetable oils and animal fats, which are non-toxic, biodegradable and renewable resources. The vegetable oils were not acceptable in diesel engine because it poses problems such as injector choking, cylinder deposits, piston ring sticking and higher smoke emissions. Biodiesel has become more attractive recently because of its environmental benefits. Methyl ester of linseed oil is derived through transesterification process. The biodiesel can be used in diesel engine without major hardware modifications. Experimental investigations have been carried out to examine the properties, performance and emission of different blends (B15, B20, and B30) of linseed oil methyl ester in comparison to diesel. Results indicate that B20 is an optimum fuel blend in terms of better performance and reduced emission than diesel fuel. However, B15 and B30 blend shows reasonable efficiencies, lower smoke, CO and HC emission.

ABSTRACT : In this research work heat transfer and fluid flow characteristics in a channel in the presence of a triangular prism has been numerically investigated in the laminar flow regime. The computations are performed for a Reynolds number of 50 and blockage ratio (b) of 0.25, where blockage ratio is the ratio of prism base to the channel height. The Navier Stokes equations along with the energy equation have been solved by using SIMPLE Technique. The unstructured triangular mesh is used for the computational domain. The results show that in the presence of triangular prism the average Nusselt number is 7.37 % more as compared to plane channel. The enhancement is due to the formation of vortices which travels long way in the downstream direction. It is further observed that the heat transfer increases with the increase in blockage ratio (b) and also by increasing the Reynolds number (Re). The effect of inserting dual prisms in different arrangement is also investigated. Heat transfer enhancement for triangular dual prisms is more as compared to the single triangular prism for same blockage ratio. However the heat transfer enhancement is associated with greater pressure drop.

ABSTRACT : The slurry erosion of two coatings applied by high velocity oxy fuel ( H.V.O.F.) processes onto shotblasted 13Cr4Ni steel was studied, and the results were compared to those obtained with 13Cr4Ni, which are commonly used for hydraulic turbines and accessories., while the microstructure and worn surfaces were characterized by optical and scanning electron microscopy. Slurry erosion tests were carried out in a modified impact test rig, in which the samples were placed conveniently to ensure grazing incidence of the particles. the slurry was compose of distilled water and quartz sand particles with an average diameter between 165 μm (AFS 50/70) and the slurry concentration content was 20000 ppm in all the tests. the three different ranges of velocity is taken i.e. 25m/s, 60m/s and 80m/s. at normal impact angle and comparison regarding the erosion resistance was determined from the mass loss results. Higher erosion will be seen at medium range of velocity i.e. at 60m/s. the coated surfaces showed higher erosion resistance than the uncoated stainless steels, with the lower volume losses measured for the Cr2O3 deposit. SEM analysis of the worn surfaces revealed intense plastic deformation in both coated and bare stainless steels, with little evidence of brittle fracture in the microstructure. The measured adhesive strength of the coatings was considered acceptable for the processes employed.

ABSTRACT : Ti-6Al-4V is known as Aerospace metal and also ASTM Grade 5. This alloy has got the popularity due to its low density, high strength to weight ratio and also for its high temperature strength. This grade of Ti- Alloy is used for aerospace, military, aircraft turbine engine compressor blades etc. Grinding is a high specific energy consuming process. At the time of grinding there are three types of actions taking place in between the grinding wheel and the surface to be ground. These are shearing, ploughing, and rubbing for different conditions of grit shape. Shearing is the process of metal removal, and the other two actions are unwanted during the process and results frictional loss. Hence to decrease the specific energy of grinding solid lubricants can be used which will reduce the frictional losses (rubbing component) and thereby decrease the grinding forces. A part of heat generated by grinding this alloy is carried out by the solid lubricants as they have good thermal conductivity. Lubricity property of the solid lubricants will reduce the frictional forces which in turn reduces the forces and specific energy consumption during grinding.

ABSTRACT : The main objective of writing this paper is to explore, as many as possible, algorithms and techniques that have been used by many researchers to provide security to the information using steganography. Steganography is the science that deals with communicating secret data by using any of the multimedia carrier, such as digital image, audio and video files. Cryptography is also used for securing the secret message but in this, feature is visible though it is not readable so point of attack is evident. So, primary goal is to hide the very existence of the embedded data. Features like undetectability, embedding capacity, robustness (resistance to various image processing methods and compression) etc make it different from other related techniques such as water marking and cryptography. This paper provides the summary of various algorithms, analysis with their pros and cons and future scope of the work.

ABSTRACT: Aluminum alloy are widely used in automotive sector due to their good mechanical properties, better corrosion resistance and wear, low melting point as compare to others. The most important property of these materials are relatively light in weight and having low production cost which make them attractive for different applications from technological point of view. The purpose of designing metal matrix composite is to add the desired attributes of metals and ceramics. This work is focused to study the change in behavior of aluminum by adding different %age amount of ‘Sic’ and ‘Al2O3’ composites. Then tensile test, hardness test, impact test performed on these samples which are produced by stir casting. Further it is concluded that as the weight %age of reinforcement goes on increasing the mechanical properties such as hardness, yield strength, ultimate strength also increases. But at the same time elongation decreases and the behavior of material changes from ductile to brittle.

ABSTRACT : This paper investigates the Multi-bandOFDM (MB-OFDM) based Ultra-Wideband for working group on short-range high data-rate Ultra-wide-Band (UWB) communications. An overview of the MB-OFDM PHYlayer architecture with its various parameters is presented and the optimal choice of critical parameters is discussed. Next, we derive the theoretical un coded bit error rate (BER) of MB-OFDM over the fading channel. Performance results over realistic UWB channel models are analyzed and compared to a pulsed-OFDM based approach. Although pulsed- OFDM was presented in the literature as an enhancement to the MBOFDM approach, simulation results showed that with same redundancy factor, both systems address almost similar BER performance.

ABSTRACT: Customer-defined product quality plays a very important role in the successiveness of a manufacturing industry. Due to this reason most of the manufacturing firms continually implements newer technologies to improve their quality standards. Product manufacturing firms believe that the way to rebound the market for their products and services is through improvements in quality, and each has outlined specific changes to their operations. A number of different types of materials, machines, tools, skill levels, and inputs have to be employed n production system and more market uncertainties because of scarcity of resources and rapid product innovations, add to the decision-making complexities in the manufacturing system. Achieving higher levels of productivity in this complex environment requires a system to rapidly adjust itself to complexities, uncertainties, and changes. Due to that reason most of the manufacturing industries are focusing on strict quality standards in their production process and implementing a quality program called Lean Manufacturing Process. This paper includes the lean practices in details from the extant literature and their benefits to present-day industries.

ABSTRACT : In This paper we have tried to reduce the values of BER using different number of transmitter antenna and receiver antenna combinations. The MIMO V-Blast System came into reality to improve the gain and error rate. Here we study the V-BLAST (Vertical-Bell Laboratory Layered Space Time) MIMO with ZF (Zero- Forcing), MMSE (Minimum Mean-Square Error), and QR-Decomposition detection algorithms with 16-QAM modulation scheme and simulate the model in AWGN environment. From simulation we find that instead of using equal number of transmitter and receiver antennas, we will get better performance of BER with increased no. of receiver antennas only compared to transmitters.

ABSTRACT : Industrial application felt the dominance of structural steel as a principal raw material. In designing and fabrication of heavy to light engineering machineries the mechanical properties like Tensile strength, Yield Strength, Elongation, Toughness and Hardness plays very important role. These properties are the important engineering criterion in today’s world. These properties deepened on number of factors. An important factor is grain size of the material. Tensile strength is higher when the grain size is smaller and vice versa. Grain size affects many properties of the polycrystalline materials like strength, Ductility, hardness & Toughness etc. Grain size of metal can be changed to attain desired properties with suitable heat treatment. In the present work structural steel has been taken and investigation carried out to develop a relation between Tensile strength, Toughness, Hardness and grain size of the metal. The grain size has been measured very accurately on computer aided image analyzer. Rests of the mechanical properties are tested on the testing machines. Verification of results has been done by determining the grain size and yields stress of the same metal with different methods used and with the hall- Fetch equation, which gives the relation between grain size and yield strength.

ABSTRACT : WWW has becomes today not only an accessible and searchable information source but also one of the most important communication channels. One of the key steps in Knowledge Discovery in Databases is to create a suitable target data set for the data mining. Clustering of data is a method by which large sets of data is grouped into clusters of smaller sets of similar data.K-means clustering algorithm suffers from two major shortcomings, right value of clusters (k) are initially unknown and effective selections of initial seed are also difficult. In this dissertation, the efficient algorithm is proposed which overcomes initial seed problem and also the validation of cluster problem. The comparison is performed between proposed fuzzy clustering algorithm, fuzzy C-means and K-mean clustering algorithm on web log dataset to test its accuracy and efficiency.

ABSTRACT : The image fusion is to integrate complementary information from several images to create a highly informative image which is more suitable for human visual perception or computer-processing tasks. Recent studies show that stationary wavelet transform (SWT) and non sub sampled contour let transform (NSCT) both turn out to be effective an deficient for image fusion. In order to take some complementary characteristics between the two muli resolution transformations simultaneously, we propose a hybrid multi resolution method by combining the SWT with the NSCT to perform image fusion. Two methods, serial NSCT aiding SWT (SNAS) and serial Standing NSCT (SSAN), are studied and compared with some state-of-the-art methods. Experimental results demonstrate that the SSAN method performs better than SNAS and the individual multi resolution-based methods, such as NSCT, SWT, complex wavelet (CWT), curve let (CVT) and wavelet-based contour let (WBCT).

ABSTRACT : In this paper, evolution of soliton pulses has been discussed. It is based on pulse spreading due to linear effects i.e. Group Velocity Dispersion (GVD) and non-linear effects which are dependent on refractive index variation due to the intensity of light, called self phase modulation (SPM). The dispersion due to GVD is balanced by the dispersion due to SPM and the resultant waves are called solitons. The solitons maintain their shapes over long distances and are found to be very suitable for long-range communication. Schrödinger equation that describes the light propagation in optical fibres, has been discussed. The applications of solitons in longrange optical communication have been dealt with. The problems and difficulties associated with solitons and their remedies have been outlined.

ABSTRACT : An Domestic Wind Mill Inverter is a DC to AC converter, used to convert a DC input voltage into a symmetrical AC output voltage of desired magnitude and frequency. Nonlinear loads are becoming a larger percentage of the total load in residential/commercial areas. Fluorescent lighting as always resulted in some harmonic generation. Now, single phase power electronic loads are a major portion of the load in many residential/ commercial facilities. The electronic devices are non-linear loads consuming harmonic distorted currents. These harmonic currents distort the voltages due to the presence of system impedances. The switching of power semiconductor devices in system results in generation of harmonics i.e. wave shape of voltage/current gets distorted from sinusoidal. These harmonics are injected into supply system and load. The harmonics adversely affect the performance of load. The basic idea is to provide the accurate study of domestic Wind Mill inverter and study of harmonic generation due to use of non-linear loads in the domestic inverter and the solution for minimizing the same. In this case, three types of loads are used such as resistive load (100 W bulbs), inductive load (40W) and capacitive load (2.5 µ f). Due to this load the harmonics generation is different and its harmonics frequency is identified by using narrow band pass filter. In this case narrow band pass filter is used with 150 Hz frequency tuned. This harmonics information is obtained on PC using microcontroller89c51 and then using passive filter the harmonics is minimized exactly for such a tuned frequency. The output voltage of a domestic Wind Mill inverter can be controlled by controlling the operation of inverter itself. The control is within the inverter itself. The most efficient method of controlling the output voltage is use pulse-width- modulation technique (PWM) within the inverter. In this technique, the on and off periods are adjusted to control the output voltage. This developed domestic PWM Inverter is identifies the order of VTHD and ITHD Harmonics free output is obtained and system performance is improved with accuracy.

ABSTRACT : Transformers are normally designed and built for use at rated frequency and perfect sinusoidal load current. A non-linear load on a transformer leads to harmonic power losses which cause increased operational costs and additional heating in power system components. It leads to higher losses, early fatigue of insulation, premature failure and reduction of the useful life of the transformer. To prevent these problems, the rated capacity of transformer which supplies harmonic loads must be reduced. In this work a typical 100 KVA three phase distribution transformer with real practical parameters is taken under non-linear loads generated due to domestic loads. The equivalent losses and capacity of the distribution transformer is evaluated using the conventional method & also by using soft computing technique using MATLAB simulation based on valid model of transformer under harmonic conditions. And finally a relation associated with transformer losses and life assessments are reviewed & analyzed and then a comparison is being carried out on the results obtained by both the methods.

ABSTRACT : Casting is a age old production technique wherein cavities are formed by a pattern into a porous and refractive material, usually sand, and then liquid metal is poured into the cavity so that it takes up the shape of the cavity, thus forming the required metal product. Various properties of sand such as grain fineness number, green compressive strength, refractive ness, clay content, moisture, mould strength, etc have an appreciable effect over the produced casting [1]. An experimental study was conducted to study the effect of three parameters, namely, moisture content of sand mould, the clay content of sand mixture and grain fineness number of sand on the tensile strength of the casting produced. Experiments were planned using the strategy of design of experiments, level and range of input parameters i.e. moisture, clay content and grain size were selected and then experiments were conducted [8,14]. In each run, the tensile strength of obtained casting was measured using the Universal Testing Machine [12]. Some considerations were put up for the hardness number, visual blow holes, surface finish, pin holes etc. Since we took into account three factors, the use of Taguchi method was made, a total of nine sand mixtures were made for the application of L9 technique [14]. These samples were then put to test for tensile strength and analysis was conducted for the collected data to study the main effects. Optimization was done by Taguchi Technique [2].

ABSTRACT : The creativity phase of Value Engineering is critical to the success of a value engineering exercise, wherein the brainstorming technique is deployed to generate ideas. But the brainstorming technique lacks direction in problem solving, and consequently the efficiency is low in generating innovative and useful ideas. This paper has explored the possibility of incorporating the theory of inventive problem solving (TRIZ) into the workshop session of the value engineering creativity phase. The paper has developed a Value Engineering (VE) process, which applies the TRIZ and integrates its creativity tools into the creativity phase of the VE workshop session and thus makes the creativity phase more systematic, more organized and more problem-focused. This attempt will significantly enhance the creativity power of the VE team beyond their collective capability and consequently enhance the efficiency and effectiveness of the VE creativity phase. A case study of highway project has indicated the workability of the modified VE creativity phase procedures and the usefulness of TRIZ tools and techniques in efficiently and effectively creating innovative ideas.

ABSTRACT : Quantum Key Distribution (QKD) is an automated method for distributing secret keys across an optical fiber. A unique feature of QKD is that its security is derived from the fundamental laws of Quantum Physics and does not therefore rely upon assumptions about the computing power of an eavesdropper. An added benefit is that the keys distributed by QKD will be highly secure. For any cryptographic system, be it of quantum or classical nature, it is important to carefully analyze the actual implementation for weak points that may compromise its principle security. Applied to QKD, these include deficiencies in the preparation of quantum data at Sender’s that can be exploited by an eavesdropper to gain information about the sifted key. These kinds of attacks are known as quantum state attack. Once the deficiencies are found, it may be possible to eliminate them by devising a better optical setup, or to remove the corresponding amount of information that eavesdropper may have obtained through additional privacy amplification. Yet, we point out that loopholes may also arise from a careless implementation of privacy amplification, e.g. improper choice of Hash function, or of insufficient authentication of the classical channel. Finally, the size of the error corrected key has to be considered when calculating the appropriate amount of privacy amplification, i.e. to distil a secure key.

ABSTRACT : For Green house climate control, in now days computerized control is required. Many old systems are based on (1) ON-OFF (2) Proportional control methods, which are not so helpful. Limitations of this methods are loss of energy, labor ,productivity. To maintain a constant climate a more sophisticated system must be used. By using fuzzy logic logic programming Green House Climate Controller (GHCC) is designed. Developed fuzzy logic controller (FLC) is based on Mamadani controller & it is based on MATLAB software. Fuzzy Logic is a mathematical technique that greatly enhances the capability of classical set theory by allowing the “degree of membership” or “truth value” to range over the interval of 0 to 1. Sets in fuzzy logic systems typically describe ranges of operations and are named using linguistic adjectives such as “slow”, “medium” or “fast”. The degree of membership describes how “slow” or how “fast” a particular value is. The controller formed sharply controls parameter such as temperature & humidity & intensity of green house to great extent. It achives dynamic optimization from economic view for green house model.

ABSTRACT : Cellular communication system provides high mobility, quick connectivity, easier to carry being light weight in comparison to bulky UHF( Ultra High Frequency), VHF( Very High Frequency) and HF (High Frequency) Radio communication systems being used in the Defence forces deployed all along the border. CDMA based cellular communication system has inherent security. Hence, it is preferred over GSM system by the Defence forces. It has smaller size, light weight and longer battery life. These factors increase mobility of land forces in different kind of terrains right from mountainous, hilly, high altitude and plains. Spill over of Transmitted Power signal across the border is a serious issue. It needs serious analysis and control. The International Border/Line of Control do not have symmetrical alignment. Hence, the layout design of the communication system becomes more important. In this paper the Ladder type of communication system design with directional sectorised antenna has been evolved. This reduces the problem of spill over of transmitted power to the other side of the International border.

ABSTRACT : Fast life and increase in per capita income in India poses ever-growing demand for foremost and convenient train services. Increased numbers of coaches in complete air-conditioned coach trains having End-On- Generation rakes (EOG) need higher capacity Diesel Generator (DG) sets to meet hotel load. In order to improve system efficiency system losses need to be reduced. This paper discusses the comparative study and present status of power supply arrangement for hotel load in Indian railway. Subsequent to that role of power factor in EOG rakes has been discussed. EOG arrangement is becoming dominant as power supply system for hotel load and power factor is a major factor which affects efficiency, performance and energy conservation of the system.

ABSTRACT : The demand for mobile communication has been steadily increasing in recent years. With the limited frequency spectrum, the problem of channel assignment becomes increasingly important, i.e., how do we assign the calls to the available channels so that the interference is minimized while the demand is met. This paper exploits the potential of the Genetic Algorithm to solve the cellular resource allocation problem. It is an optimization problem and the genetic algorithm is efficiently applied to handle this. As the number of channel is usually limited and therefore should be reused. So this paper investigates on DCA. The performance of the system is evaluated in 64 hexagonal cell arrangement having 20 channels. Numerical results show that the average call blocking probability of the system is lower than the fixed channel assignment.

ABSTRACT : An approach to multi-view face detection based on head pose estimation is presented in this paper. Support Vector Regression is employed to solve the problem of pose estimation .Three methods, the eigenface method, the Support Vector Machine (SVM) based method, and a combination of t he two methods, are investigated. The eigenface method,which seeks to estimate the overall probability distribution of patterns to be recognised, is fast but less accurate because of the overlap of confidence distributions between face and non-face classes. On the other hand, the SVM method, which tries to model the boundary of two classes to be classified, is more accurate but slower as the number of Support Vectors is normally large. The combined method can achieve an improved performance by speeding up the computation and keeping the accuracy to a preset level. It can be used to automatically detect and track faces in faceverification and identificationsystems.

ABSTRACT : Radio Frequency System In Package (SiP) consists of Integrated Circuits (ICs), surface mount device (SMD) components and embedded passive components. The routing to interconnect these components introduces high order of parasitics at RF. These parasitics affect the overall performance of the system. These interconnects include bond wires, transmission lines and transmission line discontinuities. The embedded components like capacitors and inductors are used to reduce the over all size of the system with optimal performance. This article brings out the hierarchy that connects individual active devices at the lowest level to system level connections at the highest. The article also describes the methodology for analysis and modeling of different types of interconnects.

ABSTRACT : Rapid growth of demand for various wireless communication services has led the industry and the researches to investigate on a new generation of telecommunication systems .One of the main objectives in designing and developing these systems is to provide the mobile user with a robust connection to different networks so that the users can move freely between heterogeneous networks while running their computing applications. Examples include cellular networks, metropolitan area networks, wireless local area networks and personal area networks. The combination of all these networks is usually called the beyond 3G (B3G) wireless networks. The B3G networking will enable mobile users to roam freely through heterogeneous networks on all- IP platform. Handoff is a process, which maintains a mobile users active connection as it moves within wireless networks and vertical handoff considers handoff between different types of networks or otherwise stated between different network layers. In this paper we show how performance analysis demonstrates significant improvement that can be achieved from the proposed technique and its optimization.

ABSTRACT: Transformers are critical and capital intensive assets for utility industry. It is broadly accepted that the life of a power transformer is the life of the oil/ paper insulating system, also the fact that most failures in their final on electro-mechanical base such as a short circuit condition or a mechanical failure. The ageing of insulation in Transformers is influenced by short term and long term over loads, intensity of short circuit, incidence of lightning, and internal faults. The ageing behavior is likely to be different for different types of transformers. The life span of the transformer, thus, depends initially on the design, and quality of manufacture, and later on service conditions and maintenance standard these factors vary considerably and affect the useful span of service life which therefore needs to be taken into account for residual life assessment. During the natural ageing of transformers, the insulation of winding, which is cellulose paper, deteriorates. Cellulose insulation degrades due to heating or electrical Breakdown, resulting in the production of furfural derivatives, which dissolve in oil. Hence, the chemical analysis of the Transformer oil gives evidence of changes that are taking Place in the winding insulation during operating. Deterioration in transformer cellulose decreases both its electrical and mechanical strength. In this paper a novel fuzzy based algorithm has been developed for life analysis of power transformer and implemented on three samples of transformer oil.

ABSTRACT : In this paper an effort is made to experimentally study the effect of varying workloads on heart viz... (i) At rest (ii) During exercise with respect to varying speeds and loads using a self designed and fabricated bicycle ergometer by leg pedaling at constant room temperature and humidity. It has been found that there is an increase in heart rate as exercise begins and as the work load becomes heavy, the heart rate increases immediately and continuous to increase till the exercise ends. On conducting experiment on people with different weight group, it has been found out that the rest pause required per person is different & depends upon his/her capabilities [1]. It has also been observed that with an increase in load there is marginal increase in rest time required.

ABSTRACT : The use of discrete piezoelectric patches in Smart structures for controlling the shape has been of considerable interest in recent years. Such systems of one or more dimensions can nowadays be fully modeled with the help of finite element codes. The shape control of a smart structure using surface bonded piezoelectric patches acting as sensors and actuators is examined in this work. The finite element model based on Reddy's third order laminate theory has been developed for a beam having both ends fixed. The simulation results show that both the number and location of piezoelectric patches play an important role in shape control of the structure. The shape control of the beam improves as the number of sensor/actuator pairs. The location of the sensors/actuators on the control system is more critical than their number. The sensors/actuators pairs are much more effective in shape control when placed near the regions of highest strains.

ABSTRACT : Wireless communication technology is emerging as the most effective tool in the field of communication and networking technologies. A wireless ad hoc network is a decentralized wireless network. Software Simulator is an effective tool to be used to analyze complex network architectures, routing protocols and network topologies. Global Mobile Information Systems simulator is chosen to perform the simulation results from various types of network simulators available in this work. It is a scalable simulation tool for large wireless and wireline communication systems. In mobile adhoc networks each node of the network acts as router and packet forwarder. Therefore, bandwidth and power constraints are major issues in wireless multihop networks. In the last decade, on-demand protocols, which built routes have been proposed. In this work, a performance comparison of different table driven and on-demand routing protocols have been done. The performance analysis of DBF, a table driven protocol is compared with the on demand DSR routing protocol. The quantitative measure and the performance comparison of DBF and DSR analysis using simulation in common environment using GLOMOSIM is taken up in this work. This work intends to analyze the different network parameters like control overhead, data throughput, end to end delay using simulation techniques. The simulation parameters were analyzed using the different parameters of the network viz. network nodes equal to 30, separated at a distance of 25m × 25m having transmission radius of 10 m with Random Movement of network nodes, Static Time of 10 sec, Channel capacity of 1.5 M bits/sec and MAC protocol IEEE 802.11 Distributed Coordination function. The simulation results show that the Dynamic Source Routing based on On-demand routing protocol techniques, outperforms the Distributed Bellman Ford model based on table driven routing protocol technique.

ABSTRACT : Discovering association rules between items in a large database of sales transactions has been described as an important database mining problem. Relationships between data are called associations. Association rule mining reveals such interesting relationships. These association rules are presented in a compact form, eliminating redundancy. Elimination of redundancy in the association rule set generated from large item is a challenging task. We show that the quality of rule sets from the Apriori algorithm for association rule mining can be improved by using Ant Colony Optimization (ACO). For this comparison we do a benchmark test using Abalone dataset from UCI machine learning repository.

ABSTRACT : Service restoration in power distribution system involves operating the line switches to restore as many loads as possible for the areas isolated by a fault. In case of partial restoration, the supply must be restored to highest priority customers (e.g. hospitals) and this fact should be reflected in the final solution of service restoration problem. Thus service restoration problem is formulated as multi objective, multi constraint combinatorial optimization problem. This paper proposes an Ant Colony Optimization (ACO) algorithm for a minimization problem of energy not supplied during restoration process. The proposed ACO algorithm is a new technique for combinatorial optimization borrowed from swarm intelligence. The operating time of manually controlled and automatically controlled switches is significantly different. Therefore both types of switches are considered separately.
