The optimum design of hydrostatic spherical bearings in fluid film lubrication is examined theoretically. The analytical solutions are derived for both fitted and clearance types of bearings with capillary and orifice restrictors. The optimal size based on the minimum power loss and the maximum stiffness is presented, and the difference between two types of bearings is discussed. [S0742-4787(00)02204-9]

Aim at the different characteristics from general fuel-cell vehicles of extended-range electric vehicles (E-REVs) with a fuel-cell stack as the Range Extender (RE), an energy management strategy based on minimum power loss algorithm is presented, which considers the efficiency of the fuel-cell stack and the charging and discharging efficiency of battery. The strategy is realized by neural network, simulated with the E-REV model, which is set up with ADVISOR. And a longer driving range is obtained.


Now days, expanding needs of photovoltaic cells and other solar oriented power establishments are in administration around the globe and in space. These utilizations extend from essential electric power source for satellites, remote site logical experiment and towns in creating nations to enhancing the commercial electric grid and giving fractional power for individual organization. In space, power produced by photovoltaic cells after conversion from sunlight will become mainstay of power source for Earth and geostationary satellite bodies. The conspicuous reason is daylight on earth is excessively untrustworthy, whereas in space energy can be harvest by 24 hours. The challenge is to harvest maximum energy and transmit the energy from space to earth in the form of microwave frequency with minimum power loss. In this work to harvest maximum power,s we change the directivity range of receiving antenna to -40 dB, Received microwave frequency from transmitting antenna is in the form of beam of rectangular array, In previous work, directivity ranges from 0 to -8 dB for receiving frequency 70.00 MHz causes cutoff of transmitted frequency for below 2.45 GHz, if directivity ranges increase from 0 to -40 dB then transmitting frequency ranges till 2.00 GHz will be utilized by which after conversion in rectenna we get total 223.42 MW power.
