ABSTRACT - In this paper is about design of a Motion Estimation Computing Arrays chip with embedded BIST architecture. To describes the problems of Very-Large-Scale-Integrated (VLSI) testing followed by the behavior of circuit using Verilog. The increasing growth of sub-micron technology has resulted in the difficulty of testing. BIST is a design technique that allows a circuit to test itself. In this paper the test performance achieved with the implementation of BIST is proven to be adequate to offset the disincentive of the hardware overhead produced by the additional BIST circuit. In order to generate increased attention the new Joint Video Team (JVT) is used which a standard video is coding recently. In the entire video coding system computations are performed by motion estimation computing array (MECA) and in video coding systems computation is the most important part. This video coding system must introduce design for testability (DFT) for a commercial chip. The objective of DFT is to increase the ease with which a device can be tested to guarantee for high system reliability of DFT is used to test device. BIST has an advantage because it does not use expensive test equipment and is a low cost technique. BIST used to generate simulations result and itself the analyze test responses, making tests and for quick and effective diagnoses of digital systems BIST technique is used. However, as the BIST technique is used to detect the presence of faults and specify their locations for subsequent repair in the circuit complexity. The extended techniques of , BIST are built-in self-diagnosis and built-in self-re-pair(BISR).In video coding system the complexity in computation increased thus, efficient self-detection and self-correction techniques are needed to improve reliability. Methodology is Verilog and the experimental results will be generated using the Xilinx toolsystem.

2 Overview of Hybrid Energy System in Power System
Sachin Chaudhari , Dr. A. K. Jhala

ABSTRACT - The demand of electricity increase day by day. Conventional source has own limit. This cannot fulfil the demand now a day due to resource crises. Hence renewable energy source is more important. Hybrid Renewable Energy System (HRES) is a system in which two or more than two renewable energy system get merge together to produce the electrical power. The objective of this paper is to present the literature review of the solar and wind based hybrid system. This paper discusses the feasibility and control strategy of the hybrid system. .
Keywords—RES, HRES, PV, Wind Energy, Fuel cell etc.

3 Overview of Speed Controllers for SPIM
Avinash Kumar Modi, Prof. Anuprita Mishra

ABSTRACT -Power inverter plays major role in the industry for variable speed controller. Inverters are used for conversion of the dc power to ac power. Single phase induction motors are now uses for domestic drives like mixer grinder, washing machine etc. Literature review present the work associated with the control strategy of induction motor drive. In this paper discuss first the review based on the implementation of the control technique. Also in this paper discuss the literature review based on the different type of converter uses in the controlling of the single phase induction motor.
Keywords— VSI, DC/AC, SPIM, IM, SPWM, SVM etc.

4 Watermarking for secure Communication based on Three level DWT cum SVD (3DWTS) Method: Review
Reena Agnihotri (M. Tech Scholar) and Prof. Vishal Shrivastava

ABSTRACT -Watermarking is an approach to hide the image efficiently into any covering object (image in our case) and it should do that any intruder cannot interpret it by any means, as from the proposed method that is been achieved and one can say that our generated stegno image cannot be interpreted easily by any intruder, proposed work is a unique DWT based method for watermarking. The Covering image is divided into four sub bands using transform technique DWT. Two different privet images set fixed in the HL and HH sub-bands respectively. When inserted privet images are spread within each band and use a semi random succession and only one Session key. Privet images are retrieved using the session key along with size of the images. In this approach the stegno image produce is of acceptable level with good imperceptibility and less distortion as compared to other cover image with different methods and enhance the overall security.
Keywords— DWT, Watermarking, Stegno Image etc.

5 H-Bridge Multilevel Inverter-A Review
Surbhi Sahu and Prof. Vishnu Prasad Parmar

ABSTRACT - The application of Power Electronics has changed the concept of power conversion and control strategy of electric power in a wide range. The application of solid state device is now increased for the application of power conversion. Traditional converters have many limitations like DC-Link capacitor or inductor which produce bulkiness in the circuit also they increase the cost of the power conversion. These components also produce harmonics in the system due to which the power quality issue generated. For so here is requirement of multilevel inverters. In this paper discuss the literature based on H-Bridge multilevel inverter.
Keywords— Keywords—H-Bridge, MLI, Cascaded and Power quality etc.

ABSTRACT - Electrocardiogram signal is one of the biomedical signals, which reflects electrical activity of the heart. ECG signals are widely studied and applied in clinic. The ECG signal is time varying signal, includes the valuable information related to heart diseases, but frequently this valuable information is corrupted by various noises. As noise corrupts the ECG signal it is very important as well as difficult task to suppress noises from ECG signal. So de-noising is the method of estimating the unknown signal from available noisy data. The empirical mode decomposition provides description of signal, decomposing it at different time-frequency resolution. Empirical mode decomposition is well suited tool for analysis of non-stationary signals like ECG. At first step, the signal is decomposed into transform domain where filtering procedures are applied. The noise free signal is then obtained by inverse transform. The basic idea behind this paper is the estimation of the uncorrupted ECG signal from the corrupted or noisy signal, and is also referred to as signal denoising.
Keywords— RMSE: root means square error, SNR: signal to noise ratio, ECG: Electrocardiogram, AWGN: Additive White Gaussian Noise and LMS: Least Mean Square.
