The paper describes the utility of a low cost, 1m 2 by 2m forced ventilation, micro-climate test chamber, for the support of research and teaching in mechatronics. Initially developed for the evaluation of a new ventilation rate controller, the fully instrumented chamber now provides numerous learning opportunities and individual projects for both undergraduate and postgraduate research students.

After testing many different designs, we built a rough orientation control system using a 3-axis accelerometer, able to sense and direct mirror orientation with close to one degree of precision (20 milliradians) for the entire motion range of the mirror. This level of precision is required for orientation tasks such as stowing the mirror in high winds and bringing the light spot close enough to...

many studies have been done on hybrid vehicles in the past few years. the full hybrid vehicles need a large number of batteries creating up to 300 (v) to meet the required voltage of electric motor. the size and weight of the batteries cause some problems. this research investigates the mild hybrid vehicle. this vehicle includes a small electric motor and a high power internal combustion engine...

Various kinds of biosensors were developed for the environmental control. Microbial sensor consisting immobilized yeasts and oxygen probe has been applied to estimation of 5-day BOD. The response time of BOD sensor was less than 20 mm and the minimum measurable BOD was 3 mg l-. Amperometric microbial sensor for ammonia was constructed with immobilized nitrifying bacteria and an oxyger probe. Th...
