In this paper, a finishing system with a mounted abrasive tool is proposed for finishing of metallic molds. The shape of the mounted abrasive tool is a ball-end type. When a metallic mold with curved surface is polished, the orientation of the mounted abrasive tool is not only fixed but also its revolution is locked. The motion of the mounted abrasive tool is feedforwardly controlled based on a...

This paper presents results of our educational experiments aimed to raise awareness of freshmen engineering and senior high school students on the importance of spatial skills and develop strategies for spatial learning through practice of remote operation and programming robot systems in automated manufacturing labs. In the first experiment senior high school students performed two assignments...

Developing circular economy is an important consideration for economic transformation. The resource-exhausted cities should pay more attention to circular economy development. The authors of this paper make a prompt attempt to develop an early warning system of circular economy through the fuzzy comprehensive evaluation. In the first instance, the model determines the target value of circular e...

A thermophilic mixed population of bacteria, capable of utilizing methanol as its sole carbon-energy source at temperatures up to 65 C, was selected by enrichment and studied. A maximal cellular yield of 0.42 g per g of methanol was observed at 50 to 56 C. The maximal specific growth rate of the mixed population in continuous culture at 56 C was greater than 0.32 per h. The amino acid profile o...
