the purpose of this study was to evaluate the effects of progressive motor program on improving motor skills in children with autism. in this quasi-experimental study, 16 subjects (2 girls, 14 boys) who had been diagnosed with autism in the cities of semnan and yazd were selected.  after they relatively were matched based on age, sex, grade, and the degree and severity of autism, they were divi...

Axial field flux switching motor with sandwiched permanent magnet (AFFSSPM) is a novel of flux switching motor. Based on the vector control method, the mathematical model of the AFFSSPM is derived and the operating performance of the AFFSSPM in the overall operating region is investigated.A novel control method for the AFFSSPM drive system, including the id =0, maximum torque per ampere, consta...

the aim of this study was to investigate the effect of perceptual-motor and music enrichment of environment on the development of fine and gross motor movements in infants. 32 healthy infants (5 to 8 months old) participated in this study and were divided homogenously into four groups (each group 8 subjects): three experimental groups and one control group. experimental groups had 36 training s...

Objectives: The aim of this study was to determine the effect of Perceptual-motor training on motor skills of normal preschool children (aged 4-6 years) in Esfahan city. Methods: This was a quasi-experimental study with intervention and control groups. Each group included 30 normal preschool children aged 4 to 6 years. They were selected randomly children of intervention group one empowering...

some of the important mechanical loads in the civil and military industries are variable speed and power and their efficiency. mechanical coupling of two different electric motors is suitable for these types of application. using this technique reduces energy consumption of submarine’s motion system and submarine range would be increased. but the use of this technique requires a complex control...

in conventional direct torque control (dtc), the stator flux is usually kept constant by controlling the x-axis component of the stator voltage in the stator flux reference frame. the torque is then controlled by the y-axis component of stator voltage. in this scenario, the stator current does not exceed its permissible value. however, in the so-called optimal efficiency mode, the induction mot...
