1. INTRODUCTION

Satellites have been used for years to provide communication network links. Historically, the use of satellites in the Internet can be divided into two generations. In the first generation, satellites were simply used to provide commodity links (e.g., T1) between countries. Internet Protocol (IP) routers were attached to the page link endpoints to use the links as single-hop alternatives to multiple terrestrial hops. Two characteristics marked these first-generation systems: they had limited bandwidth ....etc

The IP Multimedia Subsystem (IMS) is a standardised Next Generation Networking (NGN) architecture for telecom operators that want to provide mobile and fixed multimedia services. It uses a Voice-over-IP (VoIP) implementation based on a 3GPP standardised implementation of SIP, and runs over the standard Internet Protocol (IP). Existing phone systems (both packet-switched and circuit-switched) are supported.
The aim of IMS is not only to provide new services but all the services, current and future, that the Internet provides. In this way, IMS w ....etc

WireGL A Scalable Graphics Subsystem for Clusters
Abstract
WireGL is a framework for scalable interactive rendering on a cluster of workstations. WireGL provides the OpenGL API to each node in a cluster, virtualizing multiple graphics accelera- tors into a sort-_rst parallel renderer with a parallel interface. Using exible display manage- ment, WireGL can drive a variety of output devices, from standalone displays to tiled disp ....etc

ABSTRACT

In the future, computation will be human-centered. It will be freely available everywhere, like batteries and power sockets, or oxygen in the air we breathe. It will enter the human world, handling our goals and needs and helping us to do more while doing less. We will not need to carry our own devices around with us. Instead, configurable generic devices, either handheld or embedded in the environment, will bring computation to us, whenever we need it and wherever we might be. As we interact with these anony ....etc

A Hybrid Disk-Aware Spin-Down Algorithm with I/O Subsystem Support




Abstract

To offset the significant power demands of hard disk
drives in computer systems, drives are typically powered
down during idle periods. This saves power, but accelerates
duty cycle consumption, leading to earlier drive failure.
Hybrid disks with a small amount of non-volatile
flash memory (NVCache) are coming on the market.

Introduction

Hard disks consume a significant amount of power. In
general purpose compu ....etc

AUTO DRIVE SYSTEM
INTRODUCTION
AutoDrive is a system for automatic driving or cars and commercial vehicles on highway
It is a completely automated highway driving system which uses GPS positioning, radars and  inter vehicle signaling to aid driving
By 2030 all major interstates in the US are expected to support AutoDrive lanes with completely automated car and commercial vehicle driving
Any car updated for AutoDrive can enter these lanes and enjoy speed limits of around 13 ....etc

Each mobile uses a separate, temporary radio channel to talk to the cell site. The cell site talks to many mobiles at once, using one channel per mobile. Channels use a pair of frequencies for communication. One for transmitting from the cell site, the forward link, and one frequency for the cell site to receive calls from the users, the reverse link.
Communication between mobile units can be either half-duplex or full-duplex. In case of half-duplex, transmit and receive communications between the mobile units are not at the same time, i.e. ta ....etc

ABSTRACT
BIOMETRICS refers to the automatic identification of a person based on his or her physiological or behavioral characteristics like fingerprint, or iris pattern, or some aspects of behaviour like handwriting or keystroke patterns. Biometrics is being applied both to identity verification. The problem each involves is somewhat different. Verification requires the person being identified to lay claim to an identity. So the system has two choices, either acce ....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

Introduction
A base transceiver station or cell site (BTS) is a piece of equipment that facilitates wireless communication between user equipment (UE) and a network. UEs are devices like mobile phones (handsets), WLL phones, computers with wireless internet connectivity, WiFi and WiMAX gadgets etc. The network can be that of any of the wireless communication technologies like GSM, CDMA, WLL, WAN, WiFi, WiMAX etc. BTS is also referred to as the radio base station (RBS), node B (in 3G Networks) or, simply, the base sta ....etc

Abstract

The MIL-STD-1553 standard is used in most of the present day satellites as well as payloads within the space shuttle. The Protocol Sequencer and Subsystem Interface is a major functional element of the 1553 remote terminal design. The Very high speed integrated circuit Hardware Description Language -VHDL is used to describe hardware of Protocol Sequencer and Subsystem Interface. The functional element is divided into three units for simulation. The three units are linked using a top level program. The design is then targeted to an A ....etc
