SUPERCONDUCTIVITY is the ability of certain materials to conduct electric current with no resistance and extremely low losses. This ability to carry large amounts of currents can be applied to electric power devices such as motors and generators and to electricity transmission in power lines. For example, superconductors can carry as much as 100 times the electricity ordinary copper or aluminium wires of same size.Scientists had been intrigued with the concept of superconductivity since its discovery in the early 1900’s, but the extreme lo ....etc

Introduction
In recent years, Broadband technology has rapidly become an established, global commodity required by a high percentage of the population. The demand has risen rapidly, with a worldwide installed base of 57 million lines in 2002 rising to an estimated 80 million lines by the end of 2003. This healthy growth curve is expected to continue steadily over the next few years and reach the 200 million mark by 2006. DSL operators, who initially focused their deployments in densely-populated urban and metropolitan areas, are now challenged ....etc

Simultaneous Noncontact Measurement of Water Level and Conductivity
water level and conductivity measurement is important in many applications. geophysics, ocean engineering, and the oil industry also rely on this. The gas/oil/water separation can be an example for this. for those application, the method of Noncontact measurement is suitable. For measuring the level, techniques such as Capacitance, radar, ultrasonic, and laser have been used. measurements of level and conductivity simultaneously has no tbeen possible. a novel inductive ....etc

ABSTRACT

The discovery of superconductivity brings a tremendous change in the field of Science and Engineering from twentieth century onwards. The zero receptivity (or infinite conductivity) of a metal is known as superconductivity and this property of metal can be observed only at very low temperatures. Researche ....etc
