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...

According the authors this article is important the structure of innovation management. This structure consists of 3 elements and relationships between them Methodology, Management innovation activities and Management innovation behavior. The authors shows on ten s...

The use of the metabolism concept, expanded to include aspects of livability, is applied to cities to demonstrate the practical meaning of sustainability. Its application in industrial ecology, urban ecology, urban demonstration projects, business plans and city comparisons are used to illustrate its potential. # 1999 Elsevier Science B.V.

A compact model of torque disturbances in the brushless motors of an industrial manipulator is discussed and algorithms are given for the identification of model parameters. Thanks to its compactness, the model allows the implementation of a straightforward and effective technique for disturbance compensation. The compensation is adaptive as estimates of the parameters of the model are updated ...
