Coding of video sequences using block matching motion estimation Three Step Search algorithms
MR. S.M.KULKARNI, DR. D.S.BORMANE, DR. S.L.NALBALWAR
Abstract: Video compression plays an important role in many digital video applications such as digital libraries, video on demand, and high definition television. Exploiting the temporal correlation between two successive sequence frames we can reduce enormously the memory space needed for compression. In this context, we have applied and compared different block matching motion estimation three step search algorithms. These algorithms include Three step search algorithm (TSS), New three steps search algorithm (NTSS), Improved TSS algorithm, Enhanced TSS algorithm, Fast TSS algorithm. The performance of an algorithm is a compromise between the peak signal to noise ratio and the computing search time of the algorithm. All the algorithms are compared on the basis of PSNR and number of searching points. Choosing an algorithm depends on what we require in application. Some applications need to be executed in a minimum of computing time(real time application) and others applications must give a good PSNR as it is in the medical image processing domain. Relative merits of all algorithms are given in conclusion.

Quality assessment of 11 KV transformer by internal dissolved gas analysis using CFD
MITHU MUKHERJEE, PARTHA SARATHI DAS
Abstract: Transformer oil is usually a highly refined mineral oil that is stable at high temperatures and has excellent electrical insulating properties. When high voltages are applied to this insulating material it deteriorates and also with life span .This generates hydrocarbons in the mineral oil. The collection and analysis of gases in an oil insulated transformer was discussed as early as 1928.Many years of empirical and theoretical study have gone into the analysis of transformer fault gases.DGA usually consists of sampling the oil and sending the sample to a laboratory for analysis. On line monitoring of electrical equipment is an integral part of the smart grid. Large power transformers are filled with oil that cools and insulates the transformer winding. Mineral oil is the most common type in outdoor transformers. Fire resistant fluids also used include polychlorinated biphenyls (PCB) and silicone.

AJAY KUMAR PANDEY, AZIZ AHMAD, J.K. GARG
Abstract: An important problem is the Automatic Load Frequency Control (ALFC) which is directly related to interconnection in power systems. Other problems related to such interconnection like the Automatic Voltage Regulation (AVR) have less interaction in operation with ALFC. As the demand of electrical power is increasing and becoming a global issue, the need of interconnecting power systems is growing up; this growth represents a great challenge for power engineers, in making power systems reliable, economic and safe for both supplier and customers.

Comparison Between Isolated And Grid Connected Dfig Wind Turbine
RICHA JAIN, TRIPTI SHAHI, K.P.SINGH
Abstract: The conventional resources of energy are depleting .These resources will be finished after few years, therefore new sources of energy will be required which does not use fossil. To overcome these problems in recent years, wind energy has become one of the most important and promising sources of renewable energy, which demands additional transmission capacity and better means of maintaining system reliability. To harness the wind energy efficiently the most reliable system in the present era is grid connected doubly fed induction generator. The rotor side converter (RSC) usually provides active and reactive power control of the machine while the grid- side converter (GSC) keeps the voltage of the DC-link constant. The GSC can supply the required reactive current very quickly while RSC passes the current through the machine resulting in a delay. Both converters can be overloaded, so the DFIG is able to provide considerable contribution to grid voltage support during short circuit periods. This paper deals with the introduction of DFIG, AC/DC/AC converter control and finally the SIMULINK/MATLAB simulation for isolated IG as well as for grid connected DFIG and corresponding result and waveforms are displayed.

Implementation and Analysis of Efficient Lossless Image Compression Algorithm
MEGHA S.CHAUDHARI, S.S.SHIRGAN
Abstract: We present a new method for lossless image compression that gives compression comparable to JPEG lossless mode with about five times the speed. Our method, called ELICS, is based on a novel use of two neighboring pixels for both prediction and error modeling. For coding we use single bits, adjusted binary codes, and Golomb Rice codes. For the latter we present and analyze a provably good method for estimating the single coding parameter. Efficient, lossless image compression system (ELICS) algorithm, which consists of simplified adjusted binary code and Golomb–Rice code with storage-less k parameter selection, is proposed to provide the lossless compression method for high-throughput applications. The simplified adjusted binary code reduces the number of arithmetic operation and improves processing speed. According to theoretical analysis, the storage-less k parameter selection applies a fixed value in Golomb–Rice code to remove data dependency and extra storage for cumulation table.

LALITA A.PALANGE, SUNITA.P.SAGAT, SHASHIKANT S.HIPPARGI
Abstract: The aim of this thesis is to show the accuracy and time results of a text independent automatic speaker recognition (ASR) system, based on Mel-Frequency Cepstrum Coefficients (MFCC) and Gaussian Mixture Models (GMM), in order to develop a security control access gate. 450 speakers were randomly extracted from the audio data- base, their utterances have been improved using spectral subtraction, then MFCC were extracted and these coefficients were statistically analyzed by GMM in order to build each profile. For each speaker two different speech files were used: the first one to build the profile database, the second one to test the system performance. The accuracy achieved by the proposed approach is greater than 96% and the time spent for a single test run, implemented in Matlab language, is about 2 seconds on a common PC.

Study of Smooth Starting for LT/HT 3-phase Induction Motors by Using HFSR Starter Method for Specially Pumping Application
ANIL B.TILEKAR, PROF. MRS. A.S.SOMAN
Abstract: When three phase induction motor greater than 50 kW take very large currents with surge started directly from a 3phase supply. Actually soft starts are used for reducing this problem and to achieve smooth starting of large capacity induction motors. This will be a very useful strategy especially in Industries where various induction motors of large capacity are regularly started from a 3-phase supply. The control of soft starting is useful for prolonging the life of electric contact and helping the machinery requirements on different occasions. Motor of 50 kW and above rating draws very large current when started direct-on-line (DOL) affecting supply voltage dips which can adversely impact other equipment connected to the power grid. Sustained of large current through the motor during starting can caucuses climb temperature rise resulting in damage of the insulation of the motor windings. Therefore, the starting control of the motor needs to be operated thereby limiting its starting current. The conventional reduced voltage starting methods, such as star-delta starting and impedance starting, causes stepped variation of voltage whereas a soft-start derivative the voltage applied to the induction motor in a smooth Manner. A 3-phase reactor coil is normally employed as a soft-start. Time of soft start and stop is suitable. With this air core reactor coil soft starter voltage can be flexible to different loads. Provide motor with smooth and gradual starting current as per loads conditions

Grid Connected Photo Voltaic and Fault Analysis
RITESH DASH, KUNJAN KUMAR MOHAPATRA, PRATIK RANJAN BEHERA, DR. S.M ALI
Abstract: Fault is a common term associated with every type of electrical devices under abnormal condition. PV panel faults include installation faults, fault due to environment and material defect or degradation. All these things mainly depend upon the temperature effect and somehow related to the manufacturing defect. So fault analysis in grid connected solar PV system is a primary task to provide reliability and to avoid risks of safety hazards. We have investigated different types of fault occurring in a solar PV system mainly line to ground fault and line to line fault. These two faults mainly decrease the open circuit fault and increase the current feeding to the grid, which in turn affects the efficiency of the system. A simulation with Matlab is carried out to check the performance of the system under different fault condition.

T.BOGARAJ, J.KANAGARAJ, E.SHALINI
Abstract: To extract Maximum Power from PV system, many MPPT techniques have been employed by the researchers. This paper presents a fuzzy logic based MPPT algorithm for a 100 kW PV System. The Duty Cycle of the DC-DC Boost converter is controlled by the proposed Fuzzy MPPT control Technique and hence Maximum power is obtained from PV system. Simulations were carried out and the proposed MPPT technique is tested under different environmental conditions. The proposed method is effectively tracking the maximum power for all environmental conditions. The output voltage of the DC-DC Converter is varying one with respect to Maximum Power Point (MPP). One more DC-DC Buck-boost converter with PI control is used in order to make the DC Bus voltage constant.

Image Processing in Agriculture
MRS. LATHA, A.POOJITH, B.V.AMARNATH REDDY, G.VITTAL KUMAR
Abstract: Agriculture is the backbone of human sustenance on this world. Now a days with growing population we need the productivity of the agriculture to be increased a lot to meet the demands. In olden days they used natural methods to increase the productivity, such as using the cow dung as a fertilizer in the fields. That resulted increase in the productivity enough to meet the requirements of the population. But later people started thinking of earning more profits by getting more outcome. So, there came a revolution called „Green Revolution‟. After this period usage of deadly poisons as herbicides has increased to a drastic level. By doing so we got success in increasing the productivity but we have forgot damage done to the environment, which will arise a doubt in our sustenance on this beautiful earth. So, in this project we have implemented some methods to reduce the usage of herbicides by spraying them only in the areas where weed is present. In this paper we implemented image processing using MATLAB to detect the weed areas in an image we took from the fields.

PSNR & Eigen value based rust defect recognition & evaluation of steel coating conditions
MR. AKHTAR I. NADAF, DR. (MRS.) S.B.PATIL
Abstract: PSNR is one of the most often and universally used method for measuring quality of image. In this paper we propose a methodology for assessment of coating condition of bridge images. The defect recognition algorithm includes conversion of captured images into grey level; these grey level images are grouped into defective & non defective group. Further that is processed to plot correspondence map. The correspondence map is measure of matching image. Straight line with 450 in correspondence map indicates no defect in scene image. In contrast if correspondence map produces nonlinear image it indicates defect (rust) in scene image. The nonlinear shape of grey level distribution in correspondence map can be analyzed by calculating Eigen values. Two similar images will produce smaller Eigen value (approximately zero), whereas it will be distinctly large for dissimilar images. The PSNR determines proportion of rust in scene image with relation to reference image.

Analysis of Induction Motor with die cast rotor
RAHUL TIWARI, DR.A.K.BHARDWAJ
Abstract: This paper presents the choice between the utilizing a lower cost die cast or fabricated aluminium rotor versus the more expensive copper bar rotor. In industrialized countries Induction motors account for approximately 50% of the overall electricity use. In every field whether it is agricultural sector or the economical sector. The power consumption by a.c motors is quite enough. On an average the cost of energy consumed by the motor is nearly 60-100 times the initial cost of the motor. So the efficiency of motor is of great importance whether during the selection or during the operation. Small increase in motor efficiency can make an overall big difference between the total electricity consumption. Using copper in place of aluminium would result in a motor efficiency higher than that of the original aluminium-based motor. Consequently, the motor can then be scaled down in size, thus decreasing the individual costs of many other steps in the manufacturing process and theoretically lowering motor cost as a whole. This paper discusses the implementation of Die cast rotors, Motor efficiency, and increasing the prospect of the country by using DCR technology.

Voter Identification and Detection System using RFID and GSM to stop rigging in the elections
JHANI BHASHA SHAIK, MAZHAR HUSSAIN SHAIK
Abstract: The aim of the paper is to design and implement a secured voting system which utilizes the RFID and GSM technologies along with the Electronic Voting Machine to further improve the election process and to avoid rigging. We have developed a system which gives access to the EVM through passive RFID and GSM module. The system we have developed uses a microcontroller, a RFID reader and a GSM module. Here the voter needs to have a voter identity card with passive RFID tag printed on it. When the voter comes to the polling booth to exercise his franchise, he is directed to swipe his voter identity card on a RFID reader. The RFID reader senses the voter ID and sends this information to the microcontroller. After receiving the voter ID the microcontroller, checks weather the received voter ID belongs to the particular polling booth or not. If the voter ID belongs to the particular booth, the microcontroller generates an OTP (one time password) and sends it to the registered mobile of the corresponding voter through the GSM module. The voter has to enter this OTP using the keyboard connected to the microcontroller. If this OTP matches, the microcontroller sends an enabling control signal to the EVM to make it ready for voting. This process continues for each voter.
