Establishihg calculation model on power losses of cylindrical roller bearings for special purpose;

Mathematical model of power loss in reducing gear box on shipunder arbitrary steady operating condition;

Analysis on power loss of plasma arc in keyhole plasma arc welding

It is shown that the use of transformer-type controlled reactors allows the power losses in the power line to be reduced considerably as compared with the other options.

Although other alternative topologies (including Cuk,SEPIC,Zeta) provide the ability to convert to an output voltage less than the maximum input voltage, there are major penalty for the high voltage stress and high power losses of switching components.

Research on power consumption in FPGA design;

This paper clarifies the relations between the performance parameters and structural parameters These performance parameters include maximum film stiffness maximum load capacity and minimum power consumption On the basis of these analysis, the equations of minimum film thickness and structural parameters of restrictor are obtained.
