Terahertz (THz) research has received much attention recently. This development is due to the discovery of new THz-radiation sources and detectors such as quantum cascade lasers, photoconductive switches or electro-optic THz- detectors during the last decade. Of particular intereset are broadband Thz-spectroscopy and imaging systems operating in the frequency range 0.1-10THz. This paper describes a technique for imaging in the terahertz regime using time reversal of single cycle pulses. Specifically, the time-reversal symmetry of Maxwell?s wave ....etc

REAL TIME, TIME SEQUENCE CONTROL SYSTEM FOR MACHINES
INTRODUCTION
This project is based on VTU syllabus. The proposed system is based on ATMEL 89S52 µcontroller which is in our syllabus.
For doing this project we use some of the software like
 Embedded C for programming the application software to the microcontroller.
 Protel schematic software is used for designing the circuit diagram for this project.
 Express PCB software is used for designing the PCB for this project.
(Since PCB making is ....etc

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
