ABSTRACT


Hot isostatic processing (HIP) is the latest method to produce open porous materials, such as ceramics or metals. In this review paper, features and applications of HIPed porous materials are described. Sintering behavior under high pressure gas is also discussed in order to understand how porous materials are obtained by this method. HIPed porous materials have higher open porosity, higher mechanical strength, narrower pore size distribution and higher fluid permeabili ....etc

ABSTRACT
In cellular networks, QoS degradation or forced termination may occur when there are insufficient resources to accommodate handoff requests. One solution is to predict the trajectory of mobile terminals so as to perform resource reservations in advance. With the vision that future mobile devices are likely to be equipped with reasonably accurate positioning capability, we investigate how this new feature may be used for mobility predictions. We propose a mobility prediction technique that incorporat ....etc

INTRODUCTION
Spacecraft propulsion is used to change the velocity of spacecraft and artificial satellites. There are many different methods. Each method has drawbacks and advantages, and spacecraft propulsion is an active area of research. Most spacecraft today are propelled by heating the reaction mass and allowing it to flow out the back of the vehicle.For propulsion the required product is the velocity of the exhaust products of the reaction. All current spacecraft use chemical rocket for launch.

VLSI based asynchronous Receiver and Transmitter

The aim of this project is to design and implement an asynchronous receiver,
transmitter using verilog hardware description language. In this project we have
used serial mode of transmission because in parallel mode of transmission we need
‘n’ number of cable to transmit “n” bits of data. The following features mainly
distinguishes our project from other similar devices
- full duplex operation
- standard data format
- even ....etc

ABSTRACT

A new concept for the interplanetary and interstellar mission engine. All current spacecraft use chemical rocket for launch and this fusion propulsion system uses fusion rockets for launch. Fusion propulsion has the potential to produce high speed transportation any where in the universe. In this propulsion use fusion reactions to produce thrust to propel rockets. In order to occur fusion we have to create conditions like high temperature about 100 million degree celcius and high pressure. At these conditions plasma is fo ....etc
