ABSTRACT
Since man began to build machines for industrial use, and especially since motors have been used to power them, problems of vibration reduction and isolation have engaged engineers. Gradually, as vibration isolation and reduction techniques have become an integral part of machine design, the need for accurate measurement and analysis of mechanical vibration has grown. This n ....etc

ABSTRACT
Machining and measuring operations are invariably accompanied by relative vibration between work piece and tool. These vibrations are due to one or more of the following causes: (1) in homogeneities in the work piece material; (2) variation of chip cross section; (3) disturbances in the work piece or tool drives; (4) dynamic loads generated by acceleration/deceleration of massive moving components; (5) vibration transmitted from the environment; (6) self-excited vibration gen ....etc

Power electronics remains an emerging technology. Two important factors in power electronics system are the switching speed of the devices and the total power loss in the system. If the switching speed can be increased ,improvements may be possible i.e. current ripples in an electrical machine or physical size of passive components may be reduced. Increased switching speed may cause additional losses in a power electronics system and increase the system cooling requirement. A common problem is that high-frequency phenomena like proximity eff ....etc
