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

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, ....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 IEEE 802.15.4 based ZigBee protocol for communication and security between H ....etc

Abstract
A new zero-voltage-switching (ZVS) control approachis presented for pulsewidth modulation (PWM) buck convertersunder discontinuous conduction mode (DCM)/continuousconduction mode (CCM) boundary. This proposed technique compensatesfor control circuit delay, and hence, turns on power MOSat the instant exactly when drain-to-source voltage becomes zero.No complicated timing calculation circuits or additional externalcomponents are required. This proposed integrated ZVS controlcan be applied to other dc–dc converters as well. The ....etc
