Evolution of Word-updating Dynamical Systems （WDS） on Directed Graphs

This paper continues the research on theoretical foundations for computer simulation. We introduce the concept of word-updating dynamical systems (WDS) on directed graphs, which is a kind of generalization of sequential dynamical systems (SDS) on graphs. Some properties on WDS, especially some results on NOR -WDS,which are different from that on NOR -SDS, are obtained.     

无线网络在教学信息传输方面的应用

基于校园的无线网络覆盖方案,可以解决单一无线路由器有限的覆盖范围,又能够节约移动2G/3G通信网络接入成本.以普通的无线路由器为基础,实现一种高效、廉价的适合于校园规模的无线覆盖接入网络,可以广泛应用到学校,为移动用户提供方便、快捷的互联网络接入,提高接入效率.
