The program of＂mathematics exchange＂ which was executed by Shanghai Municipal Education Commission and the Department of Education： which is the highest performing jurisdiction in the world for mathematics. It is important to analyse and understand this project from political, cultural, social and other different perspectives. Meanwhile, This article applies Foucault and Bourdieu theories to illustrate the exchange programme and the changes of curriculum reform both in Britain and China. Practical evidences have provided the functions and the driving forces will be supplied for the further development of education continuously.展开更多

Lots of simulations have been executed in many load conditions. In this paper, the load conditions regarding an electrical vehicle for disabled people is reported. The innovation in this field concerns the integration, in the PEMFC stack mathematical dynamic model, of a synchronous electrical power drive for automotive purposes. Goal of the simulator design has been to create an useful tool which is able to evaluate the behaviour of the whole system so as to optimize the components choose. As regards the simulations with a synchronous electrical power drive, the complete mathematical model allows to evaluate the PEMFC stack performances and electrochemical efficiency.展开更多

The program of＂mathematics exchange＂ which was executed by Shanghai Municipal Education Commission and the Department of Education： which is the highest performing jurisdiction in the world for mathematics.
