In this Paper, complete models of three and six phase self commutated synchronous machine drives are presented, considering the effects of both time and space harmonics. First, the equations for calculation of machine inductances are developed. Next, "thyristor-inverter-electric machine" set is modeled in order to derive all the equations for conduction and commutation states. Finally, the resu...

background: the aim of this study was to determine the microtensile bond strength (μtbs) of ceramic and composite computer aided design‑computer aided manufacturing (cad‑cam) blocks bonded to dentin using different adhesive strategies. materials and methods: in this in vitro study, 30 crowns of sound freshly extracted human molars were sectioned horizontally 3 mm above the cementoenamel junctio...

This study examined the relationship between computer anxiety and computer selfefficacy of students and teachers in elementary and secondary schools. The sample included a total of 845 subjects from two private school systems in Turkey. The Oetting’s Computer Anxiety Scale was used to measure computer anxiety whereas the Murphy’s Computer Self-Efficacy Scale was used to measure computer self-ef...

The advent and application of computer and information technology has increased the overall success of EFL teaching; however, such success is hard to assess, and teachers prone to computer avoidance face negative consequences. Two major obstacles are high computer phobia and low computer self-efficacy. However, little research has been carried out in this area, especially from instructors’ pers...

background: with computers rapidly carving a niche in virtually every nook and crevice of today's fast-paced society, mus­culoskeletal disorders are becoming more prevalent among computer users, which comprise a wide spectrum of the ma­laysian population, including office workers. while extant literature depicts extensive research on musculoskeletal dis­orders in general, the five dimensions of...

Eighty-one female and sixty-seven male undergraduates at a Malaysian university, from seven faculties and a Center for Language Studies completed a Computer Self-Efficacy Scale, Computer Anxiety Scale, and an Attitudes toward the Internet Scale and give information about their use of the Internet. This survey research investigated undergraduates’ computer anxiety, computer self-efficacy, and re...
