几类特殊多叶函数的极值点和支撑点

设S(p,α)、C(p,α)及K(p,α)分别表示α阶的p 叶星像、凸像和近于凸函数族。本文对这些函数族的支撑点和S(p,α)的从属函数族的极值点和支撑点进行了研究,推广了Grassmann 和Perera 等人的结果。     

一种新的保持分形特征的分形变形方法

针对IFS吸引子变形过程中间出现的分形特征退化的问题,提出基于局部吸引子的近似凸包及旋转匹配的特征对应方法.IFS吸引子的局部吸引子可由独立的IFS生成,IFS中每个压缩仿射映射存在不动点,构造所有不动点的凸包,即得到局部近似凸包;证明了局部近似凸包间的相似对应等价于局部吸引子间的相似对应,并提出了通过旋转匹配的特征对应方法实现局部近似凸包的配对,最后计算所有配对下相似度最高的一组局部近似凸包匹配,确定局部吸引子间的特征对应,即IFS特征对应.对两个IFS进行线性插值可实现保持分形特征的分形变形.

Short‐term capacity allocation problem with tool and setup constraints

We consider a short‐term capacity allocation problem with tool and setup constraints that arises in the context of operational planning in a semiconductor wafer fabrication facility. The problem is that of allocating the available capacity of parallel nonidentical machines to available work‐in‐process (WIP) inventory of operations. Each machine can process a subset of the operations and a tool setup is required on a machine to change processing from one operation to another. Both the number of tools available for an operation and the number of setups that can be performed on a machine during a specified time horizon are limited. We formulate this problem as a degree‐constrained network flow problem on a bipartite graph, show that the problem is NP‐hard, and propose constant factor approximation algorithms. We also develop constructive heuristics and a greedy randomized adaptive search procedure for the problem. Our computational experiments demonstrate that our solution procedures solve the problem efficiently, rendering the use of our algorithms in real environment feasible. © 2005 Wiley Periodicals, Inc.

Attrition through a partially coordinated area defense

An area defense consists of several groups that act independently, i.e., do not communicate with each other. Each group has a fixed number of defenders and a controller that allocates these defenders optimally against the individual attackers comprising an attack. We analyze the effectiveness of this partially coordinated defense against a simultaneous attack of known size in which all attackers are considered to be equally lethal. © 2004 Wiley Periodicals, Inc.

作为历史观念的《尚书》“先王”观念

"先王"观念与"法先王"思想基本为同一范畴。"先王"观念与古代中国宗法社会紧密相连,还与中国古人对"政治制度和社会文化的延续性"的深刻认识有关。《尚书》中尚未出现"法先王"一词,但是"先王"观念非常浓厚,是中国"法先王"思想的文献源头。"先王"观念也是历史观念的重要体现,它与"殷鉴"思想、"忧患"意识一起构成了《尚书》历史功用思想的整体,并对后世产生了很大影响。     

基于心理干预视角的高校突发事件预防

心理干预在高校突发事件管理中具有不可替代的作用,它是处置高校突发事件的重要途径,也是预防高校突发事件发生的重要手段。为更好地预防高校突发事件,应建立起预防高校突发事件的大学生心理干预机制,并将其作为高校突发事件应对机制的重要组成部分。
