A general architecture of IUCELA is designed to connect multiple sensing devices with locationaware applications. Then the function of location-aware middleware which is the core componnet of the proposed architecture is elaborated. Finally an indoor forum is taken as an example scenario to demonstrate the security, usefulness, flexibiltity and robustness of IUCELA.展开更多

The step size p(k) in the algorithm varies with the variation of the region of deviation e (k) to ensure the optimization of the three performance objectives including initial convergent speed, trace ability of the time-varying system and steady disregulation. The paper demonstrates the convergence of the algorithm accompanied by random noise,展开更多

This paper analyzes the ubiquitous network application platform and its initial request for all kinds of computing and network resources. The current cloud computing technology distributed processing capabilities, which were assessed. And cloud computing in the future will provide a reference to the proposed application of research on cloud computing technology application and a new application fields.展开更多

The paper finally designed and realized the system based on the. NET platform and Ajax technology. The system uses SQL Server as the background data management system, and in the end using ADO.NET technology to realize data access. According to the actual scientific research management, system design includes integrated office, scientific research institutions, scientific research personnel, research projects and other subsystems, the majority of teachers and the laboratory research team can within the prescribed time limit, in any location by logging into the science and Technology Department of scientific research project management webpage query declaration, provides great convenience for research teachers.展开更多

Such new IT mostly comes from foreign countries and the technical manuals about how to learn such new IT and how to use its latest development tools in English. In this paper, combined with previous teaching experience and the development of a large number of networked multimedia, a preliminary study carried out on the interactive network multimedia education platform design patterns, the overall structure and system solutions. As the study is only a tentative teaching experiment based on the collaborative teaching mode, necessary improvement and modification are needed in other teaching practice. According to the curriculum characteristics and teaching situation of computer professional English, propose some teaching innovation scheme in terms of teaching contents and teaching methods, and combine computer professional English with computer professional courses to strengthen student application ability and improve teaching quality effectively.展开更多
