With the increasing demand for electric power, the economics of power transmission requires the use of high transmission line voltages. This leads to escalation of cost for conventional CTs and PTs.This paper provides an economical alternative, for the use of CTs and PTs for the measurement of current and voltage. The method is an optical method using lasers. The method employs two types of devices; free path and enclosed path devices. The basic principle of the optical method is based upon magneto-optic effect, electro optic effect and the ele ....etc

Camelina sativa is an oilseed crop and it might be used as fuel in aircrafts in the near future. A study conducted at Michigan Technological University claimed that Camelina has shown to be one of the more promising alternatives to petroleum jet fuel. They studied the whole process i.e. from planting to airplaneâ„¢s tailpipe. David Shonnard, Robbins Chair Professor of Chemical Engineering, studied the carbon dioxide emissions of jet fuel made from Camelina oil ....etc

INTRODUCTION

A. Relevance :-
The economic of India depends to a large extent on the wheels of transport. The specter of economy ruin due to depleted oil reserves has changed the interest of scientist and research work towards alternative fuels for motor vehicle. Viable substitute for motor spirit are gaseous hydrocarbons, hydrogen gas, alcohol & electricity that run on hydrocarbon gas & electricity are still in the experimental stage. While alcohol is used as a fuel chiefly in Brazil, it?s feas ....etc

Introduction
The seminar aims at introducing various other forms of computation methods. Concepts of quantum computing, DNA computing have been introduced and discussed, Particular algorithms (like the Shor's algorithm) have been discussed. Solution of Traveling alesman problem using DNA computing has also been discussed. In the seminar aims opening windows to topics that may become tomorrow's mainstay in computer science. Richard Feynman thought up the idea of a 'quantum computer', a computer that uses the effects of quantum mechanics to ....etc

ABSTRACT

The demand for high-capacity wireless services is bringing increasing challenges, especially for delivery of the ‘last mile’. Terrestrially, the need for line-of-sight propagation paths represents a constraint unless very large numbers of base-station masts are deployed, while satellite systems have capacity limitations. An emerging solution is offered by high-altitude platforms (HAPs) operat ....etc

ALTERNATIVE COMMUNICATION SYSTEMS DURING DISASTERS



PSTN or the public switched telephone network is the prime network responsible for transmitting and receiving voice, fax and data. All government and private offices, police stations, fire stations, hospitals and majority of homes and business places are serviced by the PSTN line.


. Amateur Radio operation does not use ground based infrastructure. Moreover these have limited power needs which can easily be met by batteries and generations. Therefore, it has been experienced that Ama ....etc
