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 w ....etc

ABSTRACT


A new revolution microwave life detection system which is used to locate human beings buried under earthquake rubbles has been designed.

This system operating at a certain frequency can remotely detect the breathing and heartbeat signal the status of the person under the trap can be easily judged.

The entire process takes place within a few seconds. By advent of this system the w ....etc

Gears, Gears and More Gears
What is a gear?
A gear is a wheel with teeth that mesh together with other gears.
Gears change the
• speed
• torque (rot. force)
• direction of rotating axles.
Different types of gears
Spur gears
Idler gears
Worm gears
Bevel gears
Belts & Pulleys
Spur Gears
Most “common” type of gear, a wheel with teeth
Spur gears do three things.
1. Change rot. speed
2. Change torque
3. Change direction
Make sure there isn’t too much friction between th ....etc
