CPAL BASED DESIGN OF ARITHMETIC AND LOGIC CIRCUITS

Reddy, A. Rajasekhara (2008)

As the density and operating speed of CMOS chips increase, power dissipation has become a critical concern in the design of VLSI circuits, especially in mobile and portable electronic systems. In conventional CMOS circuits ...
DESIGN AND IMPLEMENTATION OF RECONFIGURABLE FLOATING POINT ARITHMETIC UNIT

Surekha, P. S. (2008)

In recent years computer applications have increased in their computational complexity. The industry wide usage of performance benchmarks such as SPECmarks forces processor designers to pay particular attention to ...
A NOVEL APPROACH TO INFORMATION EXTRACTION AND SENTENCE ORDERING IN H1W DOMMAENT

Gusain, Amit (2008)

With the rapid growth of the World Wide Web and electronic information services, the amount of information is growing at an incredible rate. One problem that arises due to this exponential growth is the problem of information ...
INFORMATION RETRIEVAL SYSTEM USING QUERY DISTANCE AND AGENTS

Vajjagiri, Aruna Kumar (2008)

Searching for relevant information has become a skillful art in the current scenario of vast amount of available data. Often we may end up with a large amount of unrelated data. Many a times it requires a lot of human ...
FRAMEWORK FOR WEB DOCUMENT CLASSIFICATION BASED ON NAIVE BAYESIAN CLASSIFIER USING VOTING METHOD

Rajesh, G. (2008)

Automatic web document classification is the process of assigning a web documents to one or more predefined category. With the continuous increase of the information available in the World Wide Web (WWW) the importance of ...
