Authentication plays a very critical role in security-related applications like e-commerce. There are a number of methods and techniques for accomplishing this key process. In this regard, biometrics is gaining increasing attention these days. Security systems, having realized the value of biometrics, use biometrics for two basic purposes: to verify or identify users. There is a number of biometrics and different applications need different biometrics. Biometric is the most secure and convenient authentication tool. It can not be borrowed, stol ....etc

ABSTRACT
This paper describes the design and implementation of a Three Phase Power Converter (AC/DC/AC) as a fourth year group project for the Power Electronics and Drives B subject at Victoria University. The system implemented converts a three phase input voltage of 400 Vrms at a power rating of 500 W to DC by using a three phase diode bridge rectifier, and a Capacitive filter which assists in stabilising the output DC voltage produced. After that, the system provides the gate drive signal to a three phase pulse width modulated (PWM) ....etc

AIM:

Aim Of the Project Is Get the Energy From non conventional Energy Source To Convert 400v 3phase Energy. Using 3phase Zv ZC Switching Dc-Dc Convert For Fuel Cell Application.

ABSTRACT:
In spite of having many advantages, such as low
switch voltage and easy implementation, the voltage-fed dc dc
converter has been suffering from problems associated with large transformer leakage inductance due to high transformer turn ratio when it is applied to low-voltage, high-current ste ....etc

Abstract In other to save energy, several countries recently made laws related to standby power consumption. To success this exertion, we should consider not only power reduction of consumer electronics itself but also efficient automatic control in networked home environment. In this paper, we present a design approach and implementation result of control mechanism for standby power reduction. Proposed mechanism has the Host-Agent based structure and uses the IEE 802.15.4 based ZigBee protocol for communication and security between Host and A ....etc

This socket supplies the appliances with power when the user turns them on. When the user turns them off,this socket shuts the electric power off and reduces the standby power to zero.This can be a solution to electric home appliances
drawing standby power when they are plugged in.The design uses an MCU which receives signals from a PIR sensor which detects the user when approaching the socket and the appliances. A power detector provides an MCU to control the
SSR On/Off when used as an appliance switch for shutting off the standby power.The ....etc

SEMINAR REPORT ON THE SOCKET INTERFACE
1.Introduction:
We must have an interface between the application programs and the protocol software in order to use network facilities. My seminar is on a model of an interface between application programs and TCP/IP protocols. The standard of TCP/IP protocol do not specify exactly how application programs interact with the protocol software. Thus the interface architecture is not standardized; its design lies outside of scope of the protocol suite. It is further should be noticed t ....etc

A socket is defined as an end point for communication .A pair of processes communicating over a network employs a pair of sockets-one for each process.The seminar is on a model of an interface between application programs and TCP/IP protocols. The standard of TCP/IP protocol do not specify exactly how application programs interact with the protocol software. Thus the interface architecture is not standardized; its design lies outside of scope of the protocol suite.
