The lack of available and practical analysis about some regular knowledge of mobility models has limit their applications to mobile ad hoc networks. As the mobility models have the great significance effects on the network performance, and meanwhile, existing in-depth researches are mostly based on the i.i.d. mobility model which is a way of globe move, the desire for the effective and reasonable...
Data structure is the core course in the computer major. In this paper we explore the data structures teaching in principles and practices, contents, curriculum system, the practice ability and other aspects. We introduce the bilingual teaching and management mode. And we improved concepts, formed a teaching program, got to be successful in practice.
Regional economic data are mainly from statistical data. The traditional statistical data are documents of WORD or Excel. The data structure with non-hierarchical brings a lot of inconvenience to the analysis and research. In this paper, the regional economic data analysis and mining platform based on On-Line Analytical Mining (OLAM) has been studied, which provides a more convenient and efficient...
Based on information theoretic approach and projection pursuit approach, Hyva??rinen and Oja have introduced a family of novel contrast functions for independent component analysis (ICA) and proposed a Fast-ICA algorithm. Fast-ICA algorithm converges fast but it is not robust for colored sources such as biomedical signals. By optimizing Fast-ICA's contrast function, and applying natural Riemannian...
The advances in wireless communication and positioning technology have made it possible to collect large volumes of personal location data. While such data are useful to many organizations, making them public accessible is generally prohibited, because location data may imply sensitive private information. This paper investigates the challenges of publishing location data while preserving the location...
