ABSTRACT

A scramjet (supersonic combustion ramjet) is reminiscent of a ramjet. The basic components of scramjet are inlet, diffuser, fuel injector, flame holder, igniter, and combustion chamber and exhaust nozzle. The basic principle of scramjet is same as that of any type of engine, intake, compression, combustion ....etc

Introduction of Dielectrics

Dielectric is an entity ,in which equal positive and negative charges separated by equal small distance.
In which each molecule has permanent dipole moment P
This type of materials are known as polar materials
Different molecules has different different directions of the dipole moment.
In Non polar materials ,The centre of the positive charge distribu ....etc

Autonomous Stabilization System for a Coaxial Helicopter
ABSTRACT
The purpose of this project was the design of a fully autonomous stabilization system intended for systems capable of intelligent programming and navigation. This means that the design focuses mainly on the control feedback systems that control the helicopterâ„¢s motors that then provide lift to increase and decrease altitude, and produce a tilt about the helicopterâ„¢s central vertical axis which would be used for stabilization and potentially later ....etc

TRANSMISSION MEDIA
The means through which data is transformed from one place to another is called transmission or communication media. There are two categories of transmission media used in computer communications.
I. BOUNDED/GUIDED MEDIA
II. UNBOUNDED/UNGUIDED MEDIA
i. BOUNDED MEDIA:
Bounded media are the physical links through which signals are confined to narrow path. These are also called guide media. Bounded media are made up o a external conductor (Usually Copper) bounded by jacket material. Bounded media are great for LABS b ....etc

Transmission Media
Transmission media can be divided into two broad categories
• Guided Media
• Unguided Media
Guided Media
• Guided Media, Some thing physically , include twisted-pair cable, coaxial cable, and fiber-optic cable.
• Twisted-pair cable and coaxial cable use metallic (copper).
• Optical fiber is a glass or plastic cable that accepts and transports signals in the form of light.

Micro Controllers
(Cable Modems)


ABSTRACT

The present need to access internet in homes, offices, companies
etc in affordable way results in selection of efficient technology and
as a result cable modems are used. Cable modem technology brings high-
speed broadband networking to desired places through cable television
lines. Cable modems are devices that allow high-speed access to
information at a distant server may it be Internet server or video on
demand server, via a cable television ....etc

ABSTRACT
Now a day’s everything is depending up on the power. So give the reliable supply to the consumers. In distribution systems one of the major parts is SUBSTATIONS.
An electrical substation is a subsidiary station of an electricity, Generation, Transmission and distribution systems where the voltage is transformed from high to low or reverse using the transformers .Electric power may flow through several substations between generating plant and consumer and may be changed in different voltage levels .t ....etc

INTRODUCTION
1.1 INTRODUCTION:-
India is worldâ„¢s largest democracy. It is perceived to be charismatic one as it accommodates cultural, regional, economical, social disparities and still is able to stand on its own. Fundamental right to vote or simply voting in elections forms the basis of Indian democracy.
In India all earlier elections be it state elections or centre elections a voter used to cast his/her vote to his/her favorite candidate by putting the stamp against his/her name and then foldi ....etc

Optical Fiber Communications


1.0 Introduction of Optical Fiber Communications

Our current age of technology is the result of many brilliant inventions and discoveries, but it is our ability to transmit information, and the media we use to do it, that is perhaps most responsible for its evolution. Progressing from the copp cable, our increasing ability to transmit more information, more quickly and over longer distances has expanded the boundaries of our technological development in all areas. ....etc
