This paper is an overview of the sources and nature of various transient over voltages and the problems that may result in a low voltage ac distribution system. Voltage transients may be repeatable transients or random impulses and they have got remarkable effects on semiconductors, electrochemical contacts, insulation etc. Switching parallel loads on the same branch of distribution system as well as lighting are responsible for these transient overvoltages. Low voltage ac mains system should be protected from these transient overvoltages. For ....etc

Introduction

This paper explores the various techniques used to authenticate the visual data recorded by the automatic video surveillance system. Automatic video surveillance systems are used for continuous and effective monitoring and reliable control of remote and dangerous sites. Some practical issues must be taken in to account, in order to take full advantage of the potentiality of VS system. The validity of visual data acquired, processed and possibly stored by the VS system, as a proof in front of a court of law is one of such issues ....etc

Water is a vitalizing force for sustaining life on earth. About 1/3rd of world?s population depend on groundwater sources for survival. The individual requirements of water are 135 liters per day, equivalent to 49,275 liters per annum. With steady increasing population and increase in demand for water, the management for water has become a topic of serious concern. There are various techniques of wastewater management which improve the quality of water and which can be used for many purposes. . Decentralized water management is one such solutio ....etc

During several past few years, Face Recognition has become more significant. Although, other identification methods such as Fingerprints or Iris recognition are currently in use, face recognition has its own application. Principal Component Analysis (PCA) has been variously used in pattern recognition applications, especially in face recognition field. In this seminars, several techniques based on standard PCA, Fisher Linear Discriminant (FLD), Face Specific Subspace (FSS) will be discussed. We will review the developed idea used in the 2D-PCA ....etc

Abstract : A study with the goal of contributing to the development of adaptive phased array radar techniques is presented. Adaptive phased array radar is concerned with modification by closed loop control of the radar in response to a change of radar environment such that performance is improved with respect to performance before modification. This study has been concerned with selection of a quantitative measure of radar system performance and relating this measure of performance to control of phased array radar parameters. Modeling of the g ....etc

Detection of corrosion damage in aircraft wing skin structures is an ongoing NDT challenge. Ultrasonic methods are known and well-accepted techniques, which are relatively simple to carry out in terms of setup, probes and instrumentation and operator training. However, with conventional inspection from the top surface using a transducer at normal incidence (0o to the normal to the surface) producing a visual picture in the form of a C-scan, it is very tie consuming to point-by-point inspects large aircraft wing skin areas. In addition it is too ....etc

Transportation contributes to all round development of a country and hence plays a vital rate towards its progress. India, being predominantly rural in nature, road links is found to have distinct advantages over other modes of transportation. The impact of highway location on the environment is a major concern of the highway engineer and the public. If the highways are not properly located and designed it will subject to erosion and may contribute sediments to streams. The control of soil and water is basic to the protection of the road struct ....etc

Introduction

Data compression is the process of converting an input data stream or the source stream or the original raw data into another data stream that has a smaller size. data compression is popular because of two reasons

1) People like to accumulate data and hate to throw anything away. No matter however large a storage device may be, sooner or later it is going to overflow. Data compression seems useful because it delays this inevitability
2) People hate to wait a long time for data transfer. There are many known methods of data ....etc
