background: hearing loss (hl) is the most frequent neurosensory impairment. hl is highly heterogeneous defect. this disorder affects 1 out of 500 newborns. this study aimed to determine the role of dfnb2 locus and frequency of myo7a gene mutations in a population from west of iran. methods: thirty families investigated in shahrekord university of medical sciences in 2014, genetic linkage analys...

N our previous reports (OHTA and KIMURA 1969a, b, 1970), we have studied I linkage disequilibrium, that is, nonrandom association of genes between loci, caused by random frequency drift in finite populations. We have considered the situation in which a stationary distribution is reached under recurrent mutation or overdominance. We have also considered the case in which genetic variability deca...

This paper presents a novel means of sensorless drive the winding segmented permanent magnet linear motor (WS-PMLM). In order to solve problem deviation position and speed estimation mover caused by sharp changes inductance, flux linkage, back electromotive force (EMF) between segments WS-PMLM, method for compound back-EMF is proposed eliminate blind spot intersegment estimation. terms estimati...

In this work, we have proposed and experimentally validated of hybrid electromagnetic and triboelectric energy harvester using dual Halbach magnets array excited by human handy motion. Hybrid electromagnetic (EM) and triboelectric (TE) generator that can deliver an output performance much higher than that of the individual energy-harvesting unit due to the combination operation of EM and TE mec...

In this study, direct torque control (DTC) of induction motor is evaluated based on space vector modulation (SVM).DTC is a method to control machine with utilizing torque and flux of motor controlled.Direct Torque Control (DTC) is known to produce fast response and robust control in ac adjustable speed drives. However, in the steady-state operation, notable torque, flux and current pulsations o...

This paper investigates the influence of stator flux barriers on short-circuit current (SCC) and braking torque a dual three-phase permanent magnet (PM) synchronous machine. By optimizing position width barriers, machine has lower amplitude brake when fault occurs. First, SCC are analytically derived. The is proportional to PM linkage inversely inductance. square Then, equivalent magnetic circu...

the nitrite ® nitro isomerization in nitritopentaamine cobalt (iii) halides has been known. in this paper, the effect of the size of the counter ions (noncoordinated groups) on the rate of isomerization in nitritopentaamine cobalt (iii) halides, is reported. the rate of isomerization is decreased by increasing the size of the counter ions. this decrease is explained on the basis of steric inter...

Conventional manual transmissions suffer from deterioration due to wear and reduced responsiveness. Therefore, a linear electromagnetic actuator (LEA) for gear shifting has been developed. Since the LEA is direct drive, it prevents high In addition, this holding force by detent at three points. paper, sensorless position estimation performed simplify system. one coil not energized during drivin...

Axial field flux-modulation permanent magnet (AF-FMPM) machines have been developed for direct drive applications such as wind power generation, HEVs, and railway traction. However, the existing studies on AF-FMPM are limited to PM rotor structure, less research has carried out with stator structure. This paper two axial machines, i.e., NS or NN type, which all consist of same structures but du...
