1. INTRODUCTION
1.1 Micro Electro-Mechanical System (MEMS)
Micro electro-mechanical structures and systems are miniature devices that enable the operation of complex systems. They exist today in many environments, especially automotive, medical, consumer, industrial, and aerospace. Their potential for future penetration into a broad range of applications is real, supported by strong developmental activities at many companies and institutions. The technology consists of a large portfolio of design and fabrication p ....etc

SYNOPSIS
Using an experimental system that mimics stone fragmentation in the renal pelvis, the role of stress waves and cavitation in stone comminution in shock-wave lithotripsy (SWL) is noted. Spherical plaster-of-Paris stone phantoms (10mm Dia) were exposed to 25, 50, 100, 300 and 500 shocks at the beam focus of a Dornier HM-3 lithotripter. The stone phantoms were immersed either in degassed water or in castor oil to delineate the contribution of stress waves and cavitation to stone comminution. It ....etc

ABSTRACT
Solar panel converts the light energy from the sun into electrical energy. In ordinary solar panel systems, the solar panel is fixed in a particular direction. The solar panel delivers maximum energy only when it faces directly towards the sun. Since the sun is moving continuously, the solar panel cannot deliver maximum energy when the solar panel fixed at one direction.
The goal of the project is to control the solar panel cont ....etc

Crystalline silicon solar cell manufacturing requires vacuum-based processing tools for many critical steps, from mono- to polycrystalline silicon growth to thin-film depositions on silicon wafers. Manufacturing efficiencies can be optimized by considering cost-of-ownership (CoO) parameters for vacuum subsystems based on dry pumps. Careful attention to vacuum systems can make a significant contribution to reduced costs, ultimately permitting profitable production of solar cells that will encourage widespread market growth.

Crystalline-Silicon Solar Cells for the 21st Century


ABSTRACT
The worldwide market share for crystalline-silicon solar cells has
increased steadily in the last 10 years. In 1998, about 87% of the
photovoltaic modules shipped worldwide are based on crystalline
silicon. This dominance will likely continue into at least the first few
years of the 21st century. The long-term growth of crystalline-silicon
solar cells will depend on the development of low-cost ....etc

ABSTRACT
Nowadays, digital memories are used in each and every fields of day-to-day life. Semiconductors form the fundamental building blocks of the modern electronic world providing the brains and the memory of products all around us from washing machines to super computers. But now we are entering an era of material limited scaling. Continuous scaling has required the introduction of new materials.
Current memory technologies have a lot of limitations. The new memory techno ....etc

ABSTRACT
Blu-ray, also known as Blu-ray Disc (BD) is the name of a next-generation optical disc video recording format jointly developed by nine leading consumer electronics companies. The format was developed to enable recording, rewriting and playback of high-definition video (HDTV). Blu-ray makes it possible to record over 2 hours of digital high-definition video (HDTV) or more than 13 hours of standard-definition video (SDTV/VHS picture quality) on a 27GB disc. There are also plans for higher capacity discs that are expe ....etc

Abstract:

Phase-change memory (PCME, PRAM, PCRAM, Ovonic Specific Memory, Chalcogenide RAM and C-RAM) is a type of non-volatile computer recollection space. PRAMs use the unique behaviour of chalcogenide cup. Heat created by the statement of an household current changes this materials between two declares, crystalline and amorphous. Latest variations can obtain two additional unique declares, in effect increasing their storage area potential. PRAM is one of several new recollection space technological innovation contending in the non- ....etc
