Cognitive Radio (CR) is an efficient method to improve the spectrum efficiency. Industry and academic fields have focused on CR in recent years. Plenty of works on standardization of CR are concentrated among different standard organizations such as IEEE and ETSI, etc. This paper mainly introduces the work on standardization of CR in China. The proposals submitted to ITU-R from China is also introduced...
Cognitive Wireless Network (CWN), which is a set of heterogeneity networks with the capability of perceiving, planning, deciding and learning according to current multi-domain environment and end-to-end goals, is motivated by the integration, ubiquity and broadband requirements of future networks. But the rising complexity of heterogeneity networks and the need to manage this complexity make the actualization...
In the process of software production, testing is the premise to guarantee the quality of software. With the extensive application of network software, Web security test has become a key point that can not neglect. Based on the Analytic Hierarchy Process (AHP) algorithm, a new kind of Web security testing programme was introduced in this paper. According to which it realized the Web Security auto-Testing...
A novelty method of face recognition combined with the fusion of local 2DGabor mean values and 2DPCA dimension deduction based on subspace analysis is proposed. Firstly, each facial image in the training sample set is divided according to the five special face regions and then the features of five key regions are extracted through 2DGabor wavelet, mean values are calculated from feature vectors gained...
The authority management is one of the core content in all System, particularly the MIS. The realization of authority management can deal with some problems from the of fundamental, such as misoperation, misdeletion, and other human factors. It can ensure the data management in program all right, and the users of the system work "in place, but not offside." The research use ASP.NET and C#...
Rough set theory is applied to analyze the energy consumption of an industrial cold storage facility for the first time. The features of rough set theory in data extraction are analyzed. The operating parameters collected in a sample refrigerating plant between 2003 and 2007 are used to build an effective sample database. The minimal attribute set is obtained by extracting key attributes from the...
