Remarks on different reviews of Chinese character recognition

This paper gives an introduction and remarks on two review papers for Chinese character recognition. One review is made by Chinese authors, another is from American scientists. They investigate Chinese character from different language environments; they do the research from different points of view. Thus, a more comprehensive view on Chinese character recognition, which is an important branch of pattern recognition, can be provided to the readers. Meantime, one article pays attention to online process, and other paper deals with offline recognition, which complement each other. The author is the Associate Editor-in-Chief of Frontiers of Computer Science in China     

Optimal Locations of Groundwater Extractions in Coastal Aquifers

A regional water supply management model for coastal aquifers was developed. One of its outcomes is the definition of the optimized locations for groundwater withdrawal. Such a tool permits the analysis of alternative plans for groundwater extraction and the sustainable use of water resources in a coastal aquifer subject to saltwater intrusion. The principal components are the evolutionary optimization and the analytical/numerical simulation models. The optimization technique looks for the best well locations taking into consideration the economic results and the satisfaction of the societal water demand. However these two concerns are conditioned by trying to control the saltwater intrusion, i.e., preserving the environmental equilibrium. The simulation model uses the governing mathematical equations for groundwater movement to find the interface between freshwater and saltwater. Because of the non-linearity in the system and the possibility of a jumping interface, a security distance was defined. This is a controlling variable which can be set by the decision makers. The model was applied to a typical case with interesting results. For example, diagrams showing the relationship between the location of the wells and the security distance(s) are of importance to the managers. It was also crucial to have an understanding of the tradeoffs between groundwater withdrawals, positions of the wells from the coast line, and the security distance. The model was also applied to a real case in order to relate the extractions, distances and artificial recharge (not presented in this paper).     

基于集群计算机的保护定值在线校核

采用分布式计算技术，研究并实现了基于集群计算机的保护定值在线校核并行计算方法。首先分析了保护定值校核计算的计算量和计算特点，接着对可能采用的并行计算方法进行比较，最后选择了基于电网分块的并行计算方法。采用协调机加计算子机的计算模式，在协调机上执行分块算法，通过基于主导节点的图划分方法把电网分成几块，每台计算子机只校核1块电网内的保护定值，最后由协调机收集汇总计算结果。现场应用证明，该并行计算方法正确、有效。

基于共同好友数的在线社会网络社区发现算法

为了快速准确地找到在线社会网络的社区结构,提出了一种基于共同好友数和节点邻居信息的社区结构发现算法。该算法以共同好友数最多的两个节点为初始社区,不断寻找与社区连接性最强的节点,并以节点Q值为衡量标准,判断是否将该节点加入到初始社区中,最后根据节点邻居所在初始社区信息确定最终的社区划分。针对两个经典社会网络和人工生成网络数据的实验划分结果表明,该算法是可行和有效的。
