Research on Modular Manufacture Strategy under New Economic Circumstance

1 Introduction Under the new economy circumstance ,many newcharacteristicsinthe manufactureindustry occur ,such asmass customization,resources allocationin the world,product complication and so on, which has aroused moreand more awareness of people both in management theory research and in enterprise practice recently. First ofall ,because of the diversification andindividuation of customers’needs ,the changefromsellers’market to buy-ers’market ,the shortening of the life circle of products…     

Genetic Programming and Autoconstructive Evolution with the Push Programming Language

Push is a programming language designed for the expression of evolving programs within an evolutionary computation system. This article describes Push and illustrates some of the opportunities that it presents for evolutionary computation. Two evolutionary computation systems, PushGP and Pushpop, are described in detail. PushGP is a genetic programming system that evolves Push programs to solve computational problems. Pushpop, an autoconstructive evolution system, also evolves Push programs but does so while simultaneously evolving its own evolutionary mechanisms.     

On the modularization and reuse of exception handling with aspects

This paper presents an in‐depth study of the adequacy of the AspectJ language for modularizing and reusing exception‐handling code. The study consisted of refactoring existing applications so that the code responsible for implementing error‐handling strategies was moved to newly created exception handler aspects. We have performed quantitative assessments of five systems—four object‐oriented and one aspect‐oriented—based on four key quality attributes, namely separation of concerns, coupling, cohesion, and conciseness. Our investigation also included a multi‐perspective analysis of the refactored systems, including (i) the extent to which error‐handling aspects can be reused, (ii) the beneficial and harmful aspectization scenarios for exception handling, and (iii) the scalability of AOP to support the modularization of exception handling in the presence of other aspects.

基于社会网络的人名检索结果重名消解

人物重名现象十分普遍,搜索引擎的人名检索结果通常是多个同名人物相关网页的混合.该文依据同名的不同人物具有不同的社会网络的思想,利用检索结果中共现的人名发现并拓展检索人物相关的潜在社会网络,结合图的谱分割算法和模块度指标进行社会网络的自动聚类,在此基础上实现人名检索结果的重名消解.在人工标注的中文人名语料上进行实验,整体性能达到较好水平,图聚类算法能帮助连通社会网络的进一步划分,从而提高消解效果.     

Modularity in Coalgebra

This paper gives an overview of recent results concerning the modular derivation of (i) modal specification logics, (ii) notions of simulation together with logical characterisations, and (iii) sound and complete axiomatisations, for systems modelled as coalgebras of functors on Set. Our approach applies directly to an inductively-defined class of coalgebraic types, which subsumes several types of discrete state-based systems, including (probabilistic) transition systems, probabilistic automata and spatial transition systems.

基于SAA的苏云金杆菌代谢网络功能模块

比较几种常用的社团结构分析方法,讨论它们在代谢网络分析中的不足之处。模拟退火算法在代谢网络模块分析中具有一定优势,选用该算法分析苏云金杆菌代谢网络巨强连通体中的功能模块,并将所得的结果与KEGG数据库中的途径信息进行对比研究,发现大部分的模块都对应于1~2个KEGG途径。进一步的研究表明这些模块均具备重要的生物学功能意义。     

基于MAS的网络坦克作战系统体系结构分析

网络坦克作战系统是一个复杂系统,对这一系统的研究实质上是一个复杂问题的求解过程.Agent技术为此提供了模块化及抽象化的问题求解方法.将网络坦克作战系统从功能结构的角度进行了模块化分割,提出了一种基于多Agent系统(MAS)的体系结构,将系统中的协作Agent分为5类:指挥决策Agent、局域协调控制Agent、分队级协调控制Agent,系统重构Agent和评价Agent,对这种体系结构进行了分析与研究.
