This paper proposes a fault detection method for an actuator fault of an aluminum plate thermal process with input constraints. Operator-based robust right coprime factorization approach is utilized in this method. In details, after creating a mathematical model, a robust tracking operator system is designed. Following this, design of the fault detection system is given. Finally, experiment is ...

Because of the aggressive behavior of non-human primates, experimentation on unanes-thetized monkeys requires the use of a restraint system. This paper reports the development of a primate restraining system that maximizes short-term fixation and standardization of head position; this system also provides moderate limitation of body movement. The device consists of a primate chair, which was mo...

Overall fatigue strengths and hardness distributions of the aluminum alloy similar and dissimilar friction stir welding (FSW) joints were determined. The local fatigue strengths as well as local tensile strengths were also obtained by using small round bar specimens extracted from specific locations, such as the stir zone, heat affected zone, and base metal. It was found from the results that f...
