GLOBAL WARMING

INTRODUCTION:
Global warming is defined as the overall warming of the planet, based on average temperature over the entire surface.
Modern technology is based up on a number of manufacturing units exploiting the natural resources.
Due to rapid industrialization and fast population growth we are suffering from an unwanted danger of enviournment problem.
Science has given us atomic energy, comfortable communication systems etc.. for the betterment of the society but at the same time the life has b ....etc

OBJECTIVES
o History of telecommunications
o Early telecommunications
o Telegraph and telephone
o Radio and television
Computer networks and the Internet
 The history of telecommunication began with the use of smoke signals and drums in Africa, the Americas and parts of Asia.
 In the 1790s the first fixed semaphore systems emerged in Europe; however it was not until the 1830s that electrical telecommunications systems started to appear. ....etc

SYNOPSIS
Autonomous underwater gliders, and in particular autonomous underwater gliders, represent a rapidly maturing technology with a large cost-saving potential over current ocean sampling technologies for sustained(month at a time) real-time measurements.
This report gives us an overview of the main building blocks of an underwater glider system for propulsion, control, communication and sensing. A typical glider operation, consisting of deployment, planning, monitoring and recovery will be descri ....etc

Abstract
This work describes a novel method in improving the
input current total harmonic distortion (THD) as well as the power
factor of a three-phase suppressed-link rectifier-inverter circuit.
This proposed method makes use of only three bi-directional low
power static switches with a relatively simple gating circuit. This
paper illustrates how the proposed method is superior in reducing
the input current THD of a rectifier-inverter set to about 5%,
which is in line with the requirements of IEEE standard 519–1992.
This is a ....etc

Introduction
Space surveillance provides information on what is orbiting Earth. The smallest object that can be tracked is about 4 inches (10 cm) in diameter. Space surveillance provides essential information to the operators of space systems, helps to determine the capabilities of potential adversaries, predicts the orbits of objects in space to include warning of potential collisions, provides warning of an attack on a U.S. space system, and predicts space object reentry impact points.The smallest object that c ....etc
