The purpose of this study is to investigate the effect of complex training on children with the deformities including forward head, rounded shoulder posture, and lumbar lordosis. The complex training program was performed for 6 month three times per week. The complex training improved posture as measured by forward head angle (FHA), forward shoulder angle (FSA), and angle between anterior superior iliac spine and posterior superior iliac spine (APA). In the present results, complex training might overcome vertebral deformity through decreasing forward head, rounded shoulder posture, and lumbar lordosis and increasing flexibility in the children.
This paper study the design technique of 10KW Inverter-grade elevator emergency power supply system. In discharging, the input side(battery) voltage is 250V at least and this is boosted by 680V to transform 3-phase (380V/60Hz). In charging, the input side(3-phase) voltage is transformed into constant voltage(680V) and this is converted into battery voltage and charged. The battery was been using the lead storage battery. But, the battery uses the super capacitor to achieve high performance in paper. The inverter controller is made possible to optimize performance by using a double loop control system using a current controller and the voltage controller. The current controller is designed to enable the control of the error by selecting the dead-bit control method to have the most rapid response characteristic for a sampling time is reached to zero and the control voltage were selected to design approach has the under damping. Through mathematical modeling it demonstrated that the controller has reached the error to zero in exactly one sampling. Using the MATLAB computer simulation of the same design and physical model
This study aims to find a new technology of bi-directional converter for battery electric power storage device. The generally DAB(Dual Active Bridge) Converter is connected with switch(8), transformer(1) and inductance(1). It can constitute a large-capacity/low-voltage battery with ten times higher step-up/step-down ratio and soft-switching function. To obtain Step-up/step-down ratio 10 times higher and Soft-switching function to achieve a high efficiency, the toplogy is able to compose the high capacity/low voltage battery. It operates efficiently the proposed DAB converter better than the DAB converter from coupling inductance. The toplogy is operated during charge buck converter operation and during discharge boost converter operation. This experiment can be applied to the study of the system for boosting the voltage of a future ESS, BESS the UPS.
