ABSTRACT

Materials Science research is now entered a new phase where the structure and properties of materials are investigated, characterized and controlled at the nanoscale. Though as sophisticated as their larger counterparts, these devices are still burdened because they rely on an outside power. The size of the entire device is determined by the size of the power source. Batteries and other traditional sources are too large, and tend to negate the size advantages of nano devices. Also, batteries being used at present require toxic ch ....etc

ppt presantation strategies used for build successful internet based customer services

This research project is part of an overall plan to study how the IRS can better deliver Tax Assistance to taxpayers using the Internet. In 1995, the IRS created the Ask the IRS system. The system, which started as a prototype, has been in operation since then. Ask the IRS is an Electronic
Tax Law Assistance (ETLA) system that allows taxpayers to use email to send tax law questions to the Service. In the current configuration, axpayers access the system ....etc

Roll no.65



ABSTRACT

This paper presents a method to regulate the power transferred over a wireless page link by adjusting the resonant operating frequency of the primary converter. A significant advantage of this method is that effective power regulation is maintained under variations in load, coupling and circuit parameters. This is particularly im ....etc

Abstract


A multidisciplinary team of end users and suppliers has collaborated to develop a novel yet broadly enabling process for the design, fabrication and assembly of Micro-Opto-Electro-Mechanical Systems (MOEMS). A key goal is to overcome the shortcomings of the polysilicon layer used for fabricating optical components in a conventional surface micromachining process. These shortcomings include the controllability and uniformity of material stress that is a major cause of curvature and deformation in released microstructures. The appr ....etc

Silicon on insulator technology (SOI) refers to the use of a layered silicon-insulator-silicon substrate in place of conventional silicon substrates in semiconductor manufacturing, especially microelectronics, to reduce parasitic device capacitance and thereby improving performance SOI-based devices differ from conventional silicon-built devices in that the silicon junction is above an electrical insulator, typically silicon dioxide or (less commonly) sapphire. The choice of insulator depends largely on intended application, with sapphire being ....etc

IMPROVEMENT OF POWER QUALITY BY FRIENDS DEVICES



INTRODUCTION

POWER QUALITY issues are currently receiving a great deal of attention in the light of distribution generation, deregulation, liberalization and privatization of the electrical energy market. For AC transmission and distribution system, power quality broadly refers to maintaining a near sinusoidal bus voltage at rated magnitude and frequency. The power quality of a supply voltage can deteriorate due to very high-speed. ....etc

ABSTRACT

This paper provides an introduction to silicon-on-insulator (SOI) technology and the operating principles of high-voltage SOI devices, reviews the performance of the available SOI switching devices in comparison with standard silicon devices, discusses the reasoning behind the use of SOI technology in power applications and covers the most advanced novel power SOI devices proposed to date. The impact of SOI technology on power integrated circuits (PICs) and the problems associated with the integration of high-voltage and low- ....etc
