Abstract
Conventional refrigerants are being phased out worldwide to avoid ozone layer depletion and global warming and natural refrigerants are fast gaining favour nowadays. Single stage and multistage refrigeration system fail to widen the gap between heat source and heat sink temperatures required in m ....etc

ABSTRACT

Context-dependent behavior is becoming increasingly important for a wide range of application domains, from pervasive computing to common business applications. Unfortunately, mainstream programming languages do not provide mechanisms that enable software entities to adapt their behavior dynamically to the current execution context. This leads developers to adopt convoluted designs to achieve the necessary runtime exibility. We propose a new programming technique called Context-oriented Programming (COP) which addresses this ....etc

ABSTRACT

Android is a software stack for mobile devices that includes an operating system, middleware and key applications. Android is a software platform and operating system for mobile devices based on the Linux operating system and developed by Google and the Open Handset Alliance. It allows developers to write managed code in a Java-like language that utilizes Google-developed Java libraries, but does not support programs developed in native code. The unveiling of the Android platform on 5 Novembe ....etc

DEVELOPMENT OF AN A/C SYSTEM USING WASTE
HEAT OF AN IC ENGINE
ABSTRACT
The refrigerating units currently used in road transport vehicle are of Vapour Compression Refrigeration system (VCRS). This system utilizes power from the engine shaft as the input power to drive the compressor of the refrigeration system, hence the engine has to produce extra work to run the compressor of the refrigerating unit utilizing extra amount of fuel. This loss of power of the vehicle for refrigeration can be neglected by utilizing another r ....etc

ABSTRACT


A new revolution microwave life detection system which is used to locate human beings buried under earthquake rubbles has been designed.

This system operating at a certain frequency can remotely detect the breathing and heartbeat signal the status of the person under the trap can be easily judged.

The entire process takes place within a few seconds. By advent of this system the w ....etc
