The mechanism of anode-initiated breakdown in liquid organic dielectrics with long molecular chains is proposed on the basis experimental data high velocities channel propagation organosilicon and organofluorine liquids (~10 7 cm/s), which are comparable to that obtained earlier crystals same conditions. satisfactory explained within model cascade Auger transitions, developed for crystalline ma...

performing fast and accurate methods for modeling the electrical machines has been the subject of several studies and many authors proposed different procedures to attain this aim. beside the accuracy, the speed of the method is of great concern. on the other hand, the capability of the method to be changed according to the need is another important issue. finite element method provides relativ...

A miniature shrouded wind turbine aimed at energy harvesting for power delivery to wireless sensors in pipes and ducts is presented. The device has a rotor diameter of 2 cm, with an outer diameter of 3.2 cm, and generates electrical power by means of an axial flux permanent magnet machine built into the shroud. Fabrication was accomplished using a combination of traditional machining, rapid pro...
