ABSTRACT\ Turbo codes are widely used in satellite communication and 3G services. These are the major area of research in these days. Turbo codes are the forward error correcting codes that has made the near Shannon limit performance possible when suboptimal iterative decoding algorithms are used. The classical turbo encoder is built by using two […]

ABSTRACT The presence of man-made chemicals or other alteration in the natural soil environment may cause contamination of land. The most common chemicals involved are petroleum hydrocarbons, solvents, pesticides, lead and other heavy metals for e.g. Copper, Cadmium, Arsenic, lead, mercury etc. Contamination of soil not only changes the engineering properties of soil but also […]

ABSTRACT Asymmetric coplanar strip fed pattern reconfigurable antenna is presented. An asymmetric coplanar strip feed line is introduced for the first time to design a simple pattern reconfigurable antenna. The antenna consists of two arms placed orthogonally on an asymmetric coplanar strip feed line. Omni directional reconfigurable pattern is attained by alternately switching the radiating […]

ABSTRACT A mechanistic model of flexible pavement was considered and constructed to study the effects of shear modulus on performance of various pavement layers. The objective of this study was to quantify the effects of interlayer bonding by varying of the shear modulus of the contact layer. Flexible pavements are complex structures consisting of several […]

ABSTRACT For the past years DC motors are widely used in industries. There mainly preferred due to the fact that they offer good speed controllability. Most of the applications require precise speed control and accurate dynamic performance. A normal DC motor available in the market can not satisfy the requirement of the industry due to […]

ABSTRACT Wireless Sensor Networks (WSNs) consist of small nodes with sensing, computation, and wireless communications capabilities. Many routing, power management, and data dissemination protocols have been specifically designed for Wireless Sensor Networks, where energy awareness is an essential design issue. The focus has been given to the routing protocols which might differ depending on the […]

ABSTRACT This proposed research work describes a system that is used for recognition and classification of vehicles from low vision video footage captured by surveillance cameras. It’s an important step for many applications in intelligent transportation systems and video surveillance. For carrying out the above said process, first step is detection of the vehicles present […]

ABSTRACT A wireless sensor network (WSN) in its simplest form can be defined as a network of sensors, denoted as nodes, that blankets a region and provides information about it. It can sense the environment and communicate the data gathered from the monitored field via wireless links [1]. WSNs have numerous applications ranging from indoor […]

ABSTRACT The main Objective of this paper is to develop digital watermarking system for authentication of video. Here we present implementation of a visible digital video watermarking system. The system is implemented using Discrete Cosine transform (DCT) and discrete wavelet transforms (DWT) and simulated using MATLAB/ Simulink. [Full Text: PDF]

ABSTRACT In this paper, the effect of tool rake, tool shape, tool radius and tool material on the tool chip interface temperatures was investigated when machining mild steel workpiece material. The machining tests were carried out on a shaper. For temperature measurement, a test setup that was designed and constructed for temperature measurement was used. […]
