The survey shows that for the layout environment of wireless network, channel propagation model of wireless network still needs to be improved, especially low altitude propagation channel. In order to effectively study and design any random layout of wireless sensor node on the wild environment, several classic application scenes of wireless network are tested and improved in this paper. Since sample...
The normalized difference vegetation index (NDVI) time-series data, derived from satellite sensors, has been used to support land cover change detection and monitor crops successfully, but further applications are hindered by residual noise in the NDVI data. Methods for reducing noise and constructing high-quality NDVI time-series data sets can be broadly grouped into three general types, including...
Gaining a better knowledge of one's own network is crucial to effectively manage and secure today's large, diverse campus and enterprise networks. Because of the large number of IP addresses (or hosts) and the prevalent use of dynamic IP addresses, profiling and tracking individual hosts within such large networks may not be effective nor scalable. In this paper, we develop a novel methodology for...
With the development of economic globalization, more attention has been paid to cross-cultural study of consumption behavior. Mobile data services speed up the development in China after the issuance of 3G licenses. Impact of different cultural backgrounds on the consumption behavior of mobile data services must be considered when comparing their developments in China with those in other countries...
Cooperative learning is one of the basic characters of independent creative learning, and network environment is an important means of promoting cooperative learning. This paper not only analyses the theory of Web-based cooperative learning, learning content and learning pattern, but also proposes relevant implement measures combining the course features of software analysis and design. It also gives...
A practical approach is presented for determining boundary of urban traffic signal coordinated control sub-area when freeway exists. It is based on the analysis of quantitative measure of interconnection between intersection and freeway ramps. According to these quantitative indexes, those intersection(s) and ramp(s) that relate with each other closely should be delimited in the same sub-area and...
