Tata Consultancy Services breaks The ESOP myth


Excerpts:

Tata Consultancy Services (TCS), India’s largest IT services firm, has defied the trend. Not only has the country’s largest software exporter broken the ESOP myth by retaining its employee base by not using it, it has also set itself on a high growth trajectory. On the manpower front for instance, it plans to hire around 40,000 employees this financial year. At the end of Q1 FY11, the total employee str..............etc

i would like to get the ppt and report for the same.


Introduction to Eddy Current Testing
Introduction to Olympus Technologies
By Tom Nelligan and Cynthia Calderwood

Magnetism, the underlying principle behind electric motors and generators, relays and stereo speakers, is also the force that enables an important category of NDT tools called eddy current instruments. Eddy current testing is widely used in the aerospace industry and ..............etc

EDDY CURRENT BRAKES

EDDY CURRENT:
It is a swirling current set up in a conductor in response to a changing magnetic field.
By Lenz's law, the current swirls in such a way as to create a magnetic field opposing the change

Eddy Current Brakes
It slow an object by creating eddy currents through emi which create resistance, and in turn either heat or electricity.
Braking action is made by varying the strength of the magnetic field.
¢ A braking force is possible when electric current is passed ..............etc

Transformer Basics
An electrical device that transfers energy from one circuit to another purely by magnetic inductive coupling.

Review of transformer losses
No load Loss (Excitation Loss) includes the hysteresis loss and eddy current loss.
excitation loss: energy lost by reversing the magnetic field in the core by the alternating AC.
mechanical loss: bearing friction,brush friction and windage loss

Load Loss (Impedance Loss)
Stray loss: It includes distortion of air-gap flux and also due to the due to non uniform ..............etc
