Background: Tai Chi is Chinese martial art strengthening the performance of individuals. Objectives: The purpose of present study is to determine the effect of a Tai Chi exercise period on static and dynamic balance of young girls. Methods: For the purpose of this research, 32 young girls were voluntarily selected and randomly divided into two groups: Tai Chi training group (21 subjects; mean ± SD; age 22.05±2.4 weight 53.67±6.3 kg, height 1.60±0.5 m) and control group (11 subjects; mean ± SD; age 23.37±0.9 weight 53.64±7.8 kg, height 1.62±0.4 m) players. Static and dynamic balance were measured using Biodex Balance System SD three days before and after a 12-session training period with similar conditions in terms of time and place (75 minutes each session). Results: Mixed repeated measure test showed a significant difference between pre and post-tests in open eye single-foot, closed eye single-foot, open eye two-foot, and closed eye two-foot stances (p=0.001). However, no significant difference was revealed in the control group (p>0.05). While there was better balance state in all stances of Tai Chi group, no significant difference was observed between the groups in this respect (p>0.05). Conclusions: The findings of this research indicated the effectiveness of Tai Chi exercises on static and dynamic balance of young girls. Although there was no significant difference in effect of exercise between training and control groups, mean percentage of changes in training group revealed the effectiveness of exercise in training group compared to control. Therefore, Tai Chi exercises can be recommended to treat and prevent injury due to poor balance. We suggested performing Tai Chi more than 12 session in order to enhance it influences.

Considering the requirement of the multi-parameter-combined environment testing device, a kind of multi-parameter measure and control system based on wireless communication technology was studied in this paper. First, the overall structure of the multi-parameter measure and control system based on wireless communication in combined environment device was put forward, which was made up of six control subsystems: a host computer, the centrifuge and dynamic balance system, the vibration and rectification system, the temperature system, the air pressure system and the sound pressure system. Then, the communication protocol and hardware structure of the multi-computer communication system based on wireless transmission were mainly studied. And software design technology of multi-parameter measure and control system was studied in succession. Finally, the five-parameter-combined environment testing was carried out. The experimental results show that the measure and control tasks of the combined environment testing can be well finished by the multi-parameter measure and control system.

The Mathematical Model

Firstly, according to the structure characteristics of precision centrifuge, the mathematical model of its dynamic balancing system was set up, and the dynamic balancing scheme of double test surfaces, double emendation surfaces were established. Then the dynamic balance system controller of precision centrifuge was designed. Simulation results show that the controller designed can completely meet the requirements of precision centrifuge dynamic balance control system.

The objective of this paper is to monitor the electrical parameters like voltage, current, etc., remotely and display all the obtained real time values for a substation isolate. This paper is furnished to assure the load and electrical system equipment by the activation of relay, whenever the acquired parameters exceed the predefined values. Generally, this Proposed system design makes use of microcontroller, but the prototype of this circuit modelled in Proteus and can be executed by using ATmega 168 microcontroller. When supply is given to the designed hardware, all the sensors start sensing their respective parameters i. e., voltage, current, temperature etc., and modernize all the values on the display. Comparison between the problem-solving time values and the preordained values is continuously carried out by the microcontroller, if any of these values go beyond the pre-defined values, it sends fault alert to the relay, updates it on the screen and sends the same as an SMS through GSM for the rectification.
