INTRODUCTION

Consider a scientist who is responsible for the operation of robotic meteorological station located on the planet Mars (Fig. 1). The weather station is one of several dozen instrument platforms that communicate among themselves via a wireless local area network deployed on the Martian surface. The scientist wants to upgrade the software in the weather stationâ„¢s data management computer by installing and dynamically loading a large new module. The module must be transmitted first from the scientistâ„¢s workstation to a ..............etc

Reliable user authentication is becoming an increasingly important task in the Web-enabled world. The consequences of an insecure authentication system in a corporate or enterprise environment can be catastrophic, and may include loss of confidential information, denial of service, and compromised data integrity. The value of reliable user authentication is not limited to just computer or network access. Many other applications in everyday life also require user authentication, such as banking, e- commerce,..............etc

INTRODUCTION

The explosive growth of both the wireless industry and the Internet is creating a huge market opportunity for wireless data access. Limited internet access, at very low speeds, is already available as an enhancement to some existing cellular systems. However those systems were designed with purpose of providing voice services and at most short messaging, but not fast data transfer. Traditional wireless technologies are not very well suited to meet the demanding requirements of providing very high data rates wi..............etc

What is Blue eyes?
The U.S. computer giant,IBM has been conducting research on the Blue Eyes technology at its Almaden Research Center (ARC) in San Jose, Calif., since 1997. The ARC is IBM's main laboratory for basic research. The primary objective of the research is to give a computer the ability of the human being to assess a situation by using the senses of sight, hearing and touch.
Animal survival depends on highly developed sensory abilities. Likewise, human cognition depends on highly developed abilities to perceive, integrate, and in..............etc

Biometrics

What is Biometrics?

Biometrics are automated methods of recognizing a person based on a physiological or behavioural characteristic. The word biometrics means Biological Measurements. Therefore in this way we can use computers to recognize persons.

Physiological characteristics means Fingerprints, Retinal and Iris Patterns, Hand and Finger Geometry, Facial recognition etc.

Behavioural characteristics means Voice Patterns, Signature etc.

There are different biometric solutions. Some of them are Finger Print Recognition,..............etc

1. Introduction

Compact peripheral component interconnect (CPCI) is an adaptation of the peripheral component interconnect (PCI) specification for industrial computer applications requiring a smaller, more robust mechanical form factor than the one defined for the desktop. CompactPCI is an open standard supported by the PCI Industrial Computer Manufacturerâ„¢s Group (PICMG). CompactPCI is best suited for small, high-speed industrial computing applications where transfers occur between a number of high-speed cards.

It is a high-perform..............etc

INTRODUCTION

Today's microprocessors sport a general-purpose design which has its own advantages and disadvantages.

Adv: One chip can run a range of programs. That's why you don't need separate computers for different jobs, such as crunching spreadsheets or editing digital photos
Disadv: For any one application, much of the chip's circuitry isn't needed, and the presence of those wasted circuits slows things down.

Suppose, instead, that the chip's circuits could be tailored specifically for the problem at hand--say, computer-ai..............etc

Digital audio broadcasting, DAB, is the most fundamental advancement in radio technology since that introduction of FM stereo radio. It gives listeners interference ” free reception of CD quality sound, easy to use radios, and the potential for wider listening choice through many additional stations and services.

DAB is a reliable multi service digital broadcasting system for reception by mobile, portable and fixed receivers with a simple, non-directional antenna. It can be operated at any frequency from 30 MHz to 3GHz ..............etc
