论解放战争时期中间路线的兴衰及成因

抗日战争胜利初期,国共内战迫在眉睫。为挽救危局,强国富民,中间人士提出所谓中间路线,企图走“第三条道路”实现和平建国。在反动政府的强力弹压和中共的教育帮助下,中间路线退出历史舞台。民主党派的转型历程充分昭示了中国人民在中共领导下走上新民主主义道路的必然性。

Research and Design of Network Management Construction Based on Mobile AGENT

The technical characters of mobile agent （MA） originated in the distributional artificial intelligence domain is introduced. A network management construction based on agent （NMCA） is then proposed. The NMCA structure features are elaborated in detail. A prototype design of NMCA is given by using the jKQML programming. The establishment of NMCA platform will be helpful to reduce the correspondence load of network management and improves the efficiency and the expansion ability of network management systems.     

A novel fuzzy clustering algorithm for the analysis of axillary lymph node tissue sections

Recently Fourier Transform Infrared (FTIR) spectroscopic imaging has been used as a tool to detect the changes in cellular composition that may reflect the onset of a disease. This approach has been investigated as a mean of monitoring the change of the biochemical composition of cells and providing a diagnostic tool for various human cancers and other diseases. The discrimination between different types of tissue based upon spectroscopic data is often achieved using various multivariate clustering techniques. However, the number of clusters is a common unknown feature for the clustering methods, such as hierarchical cluster analysis, k-means and fuzzy c-means. In this study, we apply a FCM based clustering algorithm to obtain the best number of clusters as given by the minimum validity index value. This often results in an excessive number of clusters being created due to the complexity of this biochemical system. A novel method to automatically merge clusters was developed to try to address this problem. Three lymph node tissue sections were examined to evaluate our new method. These results showed that this approach can merge the clusters which have similar biochemistry. Consequently, the overall algorithm automatically identifies clusters that accurately match the main tissue types that are independently determined by the clinician.     

在ad hoc网络中一种新的节能路由切换模型

提出了一种基于能量消耗的路由切换模型(ERHM),它在路由维护中利用切换技术来使路由的能量消耗最小.仿真结果表明采用切换技术的ERHM模型的能量节省量要比不采用切换技术节约1.5～7.5倍,且节点的移动性越大,能量节约越多.

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。
