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

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 low tem ....etc

Fracture Mechanism In Design And Failure Analysis
Introduction
 Separation of solid into two or more pieces under applied load or stress
 Applied load or stress may be tensile or compressive in nature
 Fracture due to
1. Crack initiation
2. Crack propagation
Principles of Fracture Mechanics
 Quantitative study of failure is called fracture mechanics
 Fracture mechanics is the relationship between
 Material properties
 Stress level
 ....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
