An important aspect of applications with sensor networks is their network lifetimes. Prolonging the network's lifetime by improving the efficiency of routing algorithm has always been investigated. As for the same purpose, this paper focuses on the design of a remote life alerting system and presents an improved routing algorithm used in this system. For elder people living alone or some other people...
Discussed method and process about how to develop inquiry learning based on network environment. Researched inquiry learning from the beginning, core, way, key point, independent evaluation, and the resources construction. Constructed a inquiry learning website, and does the effective practice. The results are good.
This paper makes a research on the application of GIS system to intelligent terminal PDA and its capability and storage mechanism. It studies how to organize and manage the massive regular grid data of GIS real-timely and visually while the storage capability and speed is so limited. On organization of grid data, it puts forward a data management model that combined pyramid model with one-to-four...
Synchronization phenomena, an emergent property in networks of interacting dynamical elements, are widely observed in nature, and have become the subject of intense research. Here we will investigate the synchronization rate problem in coupled limit-cycle and chaotic oscillators. Based on the mode decomposition method and Gershgörin's discs theorem, some sufficient conditions for synchronization of...
