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, high-current ste ....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

This remote controlled car can be moved around using practically any kind of remote such as TV,AC etc.
It makes use of the fact that the remote emits IR(infrared).
This property is made use of by using an IR receiver,which is a very cheap sensor.
In this instructable you will learn how to
1. Interface IR receiver to Arduino.
2. Interface 2 motors to Arduino.
3. Combine the above 2 setups.
NOTE:This remote controlled car has a disadvantage of not work outside in sunlight. ....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

One of the major issue in power system is the losses occurs during
the transmission and distribution of electrical power. As the
demand increases day by day, the power generation increases and
the power loss is also increased. The major amount of power loss
occurs during transmission and distribution. The percentage of loss
of power during transmission and distribution is approximated as
26%. The main reason for power loss during transmission and
distribution is the resistance of wires used for grid. The efficiency
of power transmission ....etc
