Real-time systems play a considerable role in our society, and they cover a spectrum from the very simple to the very complex. Examples of current real-time systems include the control of domestic appliances like washing machines and televisions, the control of automobile engines, telecommunication switching systems, military command and control systems, industrial process control, flight control systems, and space shuttle and aircraft avionics.

All of these involve gathering data from the environment, processing of gathered data ....etc

Definition
Micro-electromechanical systems (MEMS) is a technology that combines computers with tiny mechanical devices such as sensors, valves, gears, mirrors, and actuators embedded in semiconductor chips.




Overview
MEMS are already used as accelerometers in automobile air-bags. They've replaced a less reliable device at lower cost and show promise of being able to inflate a bag not only on the basis of sensed deceleration but also on the basis of the size of the person they are protecting. Basically, a MEMS device contains micro-cir ....etc

This is a new technique for the protection of transmission systems by using the global positioning system (GPS) and fault generated transients. In this scheme the relay contains a fault transient detection system together with a communication unit, which is connected to the power line through the high voltage coupling capacitors of the CVT.

Relays are installed at each bus bar in a transmission network. These detect the fault generated high frequency voltage transient signals and record the time instant corresponding to when the initial ....etc

Now a day it is very important to increase the efficiency of IC engines due to many factors such as fuel economy, fuel crisis and ultimately to increase the output. Here comes the importance of effective cooling systems in IC engine.

The advanced cooling concepts are proposed to overcome the shortcomings arising when applying conventional cooling methods. The various effects of overheating the engine components due to the improper cooling and conventional cooling methods have also being discussed.

System Analysis
Problem Definition Identity verification is arguably the most important and certainly the most fundamental of IT security requirements: nearly all other functions in this field (such as access control, data confidentiality, digital signatures etc.) rely for their successful operation on some part of the system being able to confirm a person's identity. Unfortunately, in practice, proof of identity is consistently the weakest page link in the security chain: the vast majority of Systems today still rely on passwords or PINs - i ....etc
