Energy storage device is widely used in vehicle and ship, as the only or the backup DC power supply. For multiple energy storage devices operating in parallel, it's necessary to adopt current-sharing control to improve the safety and the reliability of these devices. There are many current-sharing algorithms, such as the maximum current current-sharing method, the average current current-sharing method,...
This paper gives out a PUB/SUB-based application server software, which aims at improving the coarse granularity of the pushed information in current LBS systems. Taking the advantage of PUB/SUB system's asynchronous, loosely-coupled and multiplex communication mechanism, the server software pushes LBS information with its granularity refined. By combining position information and the PUB/SUB paradigm,...
Along with the rapid development of e-learning market and the widespread popularity for universities in China, the purchase and sales contracts of Blackboard (BB) platform has been signed by Shanghai University, which has become the second largest Blackboard user in China since 2010. BB is planned to integrate school's existing systems which are educational management system, the LEHU Forum and the...
Motion estimation (ME) from image sequences is of primary importance for applications like target tracking, velocity measurement and vision guidance. By the fact that the wavelet transform has the ability to handle the signals with the non-stationary, time-varying properties, a novel spatio-temporal filtering approach based on the Continuous Wavelet Transform (CWT) to realize the motion selectivity...
This paper shows that the bilingual teaching plays an important role in universities and it mainly aims at raising university students' comprehensive ability. Combined the practice of bilingual teaching with media on advanced mathematics, the authors provide new ideas to the new course reformation on bilingual teaching.
The arrival of knowledge-based economy ages has put forward new request and challenge to traditional management model of adult education. It needs more students to create more value to school. Applying CRM in Management to analyze the influence factor of adult education student's study demand, this paper try to summarize the essential feature of adult education student's study, and utilize SPSS to...
Hezhe ethnic group is an old nation which has formed own special culture through the long history. As one of the inspirit cultures, the art of pattern is very heavy and complicated. Because of the historical reason, many patterns of art have lost. Hezhe ethnic group folk arts is a kind of important culture heritage that belongs to the entire human, we should realize the valuable culture heritage's...
Elliptic complex number and hyperbolic complex number has its own corresponding geometry of space, which should be different in different coordinate transformation, but in their respective geometry of space, if the coordinate transformation is indicated by responded complex number, then a unified equation in the form will be given: z'= p z + q.
Clifford Algebra is also known as multi-vector calculus, it has more advantages than the usual mathematical tools like vector, tensor, spinor and exterior differential form. This text introduces the basic knowledge and complex number property of Clifford algebra from the two-dimensional geometric space to the three-dimensional geometric space, showing the superiority of Clifford algebra and reflecting...
We have studied the theory of the process of knowledge transfer, the characters of the knowledge diffusion among teachers and students and the related factors. We find there are four stages in the process of knowledge diffusion among teachers and students in local universities and each stage is influenced by different factors. A conceptual model about the factors that effect knowledge diffusion among...
