ABSTRACT



Because of high requirements in power, efficiency, installation space and weight, the design of electrical machines for hybrid electrical vehicles is a particular challenge. This seminar describes a comparative study allowing the selection of the most appropriate electric-propulsion system for a parallel hybrid electric vehicle (HEV). This seminar is based on an exhaustive review of the state of the art and on an effective comparison of the performances of the four main electric propulsion systems, namely the d ....etc

Abstract

In this project we're trying to develop a control and safety monitoring system for
a Nuclear Power Plant using RTOS. For that purpose we're using the simulator version of VxWorks-Tornado Prototyper which is included with VxSim.

VxSim is a port of VxWorks to the various host architectures. It provides a simulated
target for use as a prototyping and test-bed environment. In most regards, its capabilities are identical to a true VxWorks system running on target hardware. Users can page link in applications and rebuild the VxWorks ....etc

Purpose of our course project is to develop DTMF signal controlled house monitoring
system based on PIC Microcontroller. The device is connected to phone line and is controlled by
DTMF signal emitted by DTMF encoder in stationary or mobile phones. In presence of incoming
call the device pick-up the phone and answer the call connecting to the line. User can press
buttons and control the system remotely. Function of keys should be known initially (read
manual in appendix B). The functions are:
· speakerphone monitoring (you can lis ....etc

A ticket to Super Bowl XXXV in Tampa Bay, Florida, didnâ„¢t just get you a seat at the biggest professional football game of the year. Those who attended the January 2000 event were also part of the largest police lineup ever conducted, although they may not have been aware of it at the time. The Tampa Police Department was testing out a new technology, called FaceIt, that allows snapshots of faces from the crowd to be compared to a database of criminal mugshots. ....etc
