The occurrence of the motor shaft voltage and bearing current caused by inverter will aggravate damage lead to premature failure bearings. Many types equipment are being shut down due currents, such as filters, insulated bearings grounding brushes. Traditional suppression measures cannot eliminate mechanism under is not clear. In this paper, analyzed in detail. influences different working cond...

in this paper, a multi purpose function is presented for optimum design in circular hydrostatic axial bearings. one or more parameters that are directly or indirectly dependent on given data are optimized. usually in the local optimization methods, it is not possible to optimize several parameters simultaneously. in this research, simultaneous optimization of the power loss and the oil temperat...

abstract pistachio ( pistacia vera l.) is an important crop in our country and has a unique position in export goods. in respect to better nut quality this research was conducted during 2005-2006. macro and micronutrients were used as foliar application to surmount soil limitations in nutrient uptake and alternate bearing control with “owhadi” cultivar in rcbd with 3 replications. the treatment...

background: constraint induced movement therapy is one of the new therapeutic interventions that limits the performance of intact upper limb with increased use of the affected limb. aim of this study was to investigate the effects of  modified constraint induced movement therapy on weight bearing & protective extension in children with hemiplegic cerebral palsy. methods: 21 hemiplegic children ...

background: joint position sense (jps) is comprised of sensory input from several sources, including skin, joint capsule/ligaments, and muscular receptors. if the muscle receptors play a leading role in detecting joint position awareness, then muscle fatigue might yield a declination in jps. the aim of this study was to evaluate if a sustained fatiguing contraction of the tibialis anterior (ank...

in order to develop more efficient engines, it is essential to optimize the lubrication circuit of the power train systems. in this paper, during an engine design and development process, a network analysis of the engine lubrication system is described in detail. two elements have been added to the lubrication circuit in the modified engine. these elements are hydraulic lifters and an anti-drai...

bearing capacity prediction of axially loaded piles is one of the most important problems in geotechnical engineering practices, with a wide variety range of methods which have been introduced to forecast it accurately. machine learning methods have been reported by many contemporary researches with some degree of success in modeling geotechnical phenomena. in this study, a fairly new machine l...
