软件企业知识共享影响因素模式研究

知识被认为是企业最重要的战略资源，企业成功与否取决于知识管理的成败。知识共享是企业实施知识管理活动的重要议题。本文详细分析了软件企业员工知识的特点，识别出影响员工知识共享的关键因素，提出了影响软件企业知识共享的基本模式。     

因素空间理论与知识表示的数学框架（Ⅸ）──均衡函数的构造与Weber－Fechner特性

本文是文［１－８］的继续，该文及后续论文仍将系统地研究因素空间理论及其在知识表示中的应用。该文研究均衡函数的构造，并且引入了激励型均衡函数和混合型均衡函数。特别，从混合型变权出发，我们得到与ＷｅｂｅｒＦｅｃｈｎｅｒ定律一致的综合函数。     

Weighted allocation rules for standard fixed tree games

In this paper we consider standard fixed tree games, for which each vertex unequal to the root is inhabited by exactly one player. We present two weighted allocation rules, the weighted down-home allocation and the weighted neighbour-home allocation, both inspired by the painting story in Maschler et al. (1995) . We show, in a constructive way, that the core equals both the set of weighted down-home allocations and the set of weighted neighbour allocations. Since every weighted down-home allocation specifies a weighted Shapley value (Kalai and Samet (1988)) in a natural way, and vice versa, our results provide an alternative proof of the fact that the core of a standard fixed tree game equals the set of weighted Shapley values. The class of weighted neighbour allocations is a generalization of the nucleolus, in the sense that the latter is in this class as the special member where players have all equal weights.     

层次版图连接关系提取

本文提出了一种新的层次版图连接关系提取算法,其利用投影法和版图倒序树(Inverse Layout Tree,简记为ILT)构建同一原始图形在不同层次单元之间的关联,并在基于边的扫描线算法的基础上利用组合器的方法建立版图数据的正确连接.此算法能够极好的保持版图中原有的层次,在此算法基础上进行的层次网表提取能够使层次LVS得到最大程度的支持;同时,算法具有很高的效率,只需占用很少的资源.目前,九天EDA系列工具中的层次版图验证工具已经采用此算法.

Making decisions in the absence of clear facts

Bennis and O’Toole [Bennis, W.G., O’Toole, J., 2005. How business schools lost their way. Harvard Business Review 83, 96–104] have recently argued that decision makers need guidance in ‘making decisions in the absence of clear facts’. As such, decision makers must be able to resourcefully use whatever limited information is available and advantageously portray its implications. Based on recently published theory which directly addresses this requirement, this paper demonstrates, through a practical example, how decision makers can make systemic decisions in situations characterized by extremely limited information and, furthermore, what form such decisions can take. Evidence is provided, therefore, that operational research can effectively address what appears to be a gap in management training.     

On the multiplicities of eigenvalues of a Hermitian matrix whose graph is a tree

A different approach is given to recent results due mainly to R. C. Johnson and A. Leal Duarte on the multiplicities of eigenvalues of a Hermitian matrix whose graph is a tree. The techniques developed are based on some results of matching polynomials and used a work by O. L. Heilmann and E. H. Lieb on an apparently unrelated topic.      

Realization of a 450 mhz cable tv system compatible with existing networks

This paper describes the realization in West Germany of a 450 MHz cable TV system, which matches into the infrastructure already formed by the existing 300 MHz systems. The studies and developments done to achieve this are described, and the results of a field trial detailed. Finally the impact of the new MAC standard is discussed.
