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

SLIVER GENERATION REDUCTION IN TRIMMING OF ALUMINUM
Seminar
Presented by
VIVEK ASHWIN
DEPARTMENT OF MECHANICAL ENGINEERING
N S S COLLEGE OF ENGINEERING
PALAKKAD-678008, KERALA.

SYNOPSIS

Aluminum auto body sheets produce appreciable amounts of slivers during trimming operations when trimmed with dies conventionally designed for steel sheets. The slivers can be carried through downstream processes and cause damage to the surface of formed parts resulting in costly manual repair. T ....etc

Abstract
Conditions were determined for consistent coupling of a CO2 laser beam to weld 5182 aluminum
alloy sheet. Full penetration butt and bead-on-plate welds on 0.8 and 1.8 mm sheets were
performed. Process conditions examined included beam mode, spot size and irradiance,
shielding gas flow, and edge quality and fitup. The observed weld quality variations with the
different process parameters were consistent with physical phenomena and a threshold irradiance
model. Optimal conditions were determined for obtaining consistent wel ....etc

Aluminum Electrolytic Capacitors

Aluminium electrolytic capacitors are widely used in power supply circuitry of electronic equipment as there after several advantages over other types of capacitances. The selection of a capacitor for an application without knowing the basics may result in unreliable performance of the equipment due to expanitor problems. It may lead to customer dissatisfaction and damage market to potential or the image of a reputed company. The aluminium eletrolytic capacitors are suitable to be used when a great capacitanc ....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
