Professor Ma Limin of Huazhong University of Science & Technology, Wuhan, and other colleague have reported their research on the next generation Geometrical Product Specification and verification (GPS).
ISO/TC213 on GPS has been working towards harmonizing previously standardized practices in tolerance and related metrology, and published the next generation of the GPS language now. The master plan structure of the improved GPS system is constructed with a matrix model, which includes four kinds of GPS standards, fundamental, global, general and complement GPS standards. ISO/TC213 will offer the full technical specifications of the product designing, manufacturing, verification and evaluation, which are based on simplicity and minimization of total cost. They have analyzed the matrix model of the improved GPS standards, and presented the rules of preparing standards, key technology as well as the research subjects on the new GPS.

A noise-reduced measures with Independent Component Analysis (ICA) during the process of data acquisition of vibration signals of rotating machinery has been introduced for the fault diagnosis of rotating machinery by Prof. Ji Zhong and Prof. Jin Tao of Chongqing University. The noise-reduced method based on ICA has been studied to extract features during the process of run ? up and run?down of the rotationg machinery. The experimental results show that this method can simply and effectively remove the noise contained in the sampled vibration signals

(3) Snow Melting Systems Using Ground-Source (Source: JSME)

Hideo Otake, Hokkaido Institute of Technology

Road snow melting is a common problem in the world and a variety of countermeasures are adopted according to local conditions. Ground-source heat pumps use relatively constant temperature of the earth to provide heating of road in cold climate regions.? The snow melting system using ground-source heat pump consists of a borehole, a ground-source heat pump and pavement. Fluid as a heat carrier circulates through heat exchange pipes of the pavement and the borehole. The snow melting system can store the thermal energy collected by pavement of the car park using a circulated pump in summer and melt the snow on the car park using a ground-source heat pump in winter.? The ground-source heat pump is being actively promoted today in North America and northern Europe.? However, there are only a few examples in Japan of a ground heat using system being put to practical use. The reasons behind its unpopularity in Japan include the high cost of installing the heat exchanger and ground-source heat pump.? Recently, the development of the system to reduce the installing and running cost and to optimize the system design is carried out.

(4) Responsive hydrogels (Source: JSME)

Responsive hydrogels are a class of new materials that drastically change their material properties due to the change of temperature, pH, brightness, etc. Hydrogels consist of various types of polymers with high water content. Potential applications of responsive include drug delivery systems, tissue engineering and Micro Electro
Mechanical System (MEMS). Responsive hydrogels are exited by the change of temperature or pH alone, making their actuation very simple, and respond quickly when they are miniaturized. Thus, they would find more applications in small sized machines and devices. Therefore, though the pharmaceutical and bioengineering applications of responsive hydrogels have been studied by many researchers so far, responsive hydrogels may find their applications in other fields such as MEMS, micromachines, etc.
