A Reusable Multi-Agent Architecture for Active Intelligent Websites

In this paper a reusable multi-agent architecture for intelligent Websites is presented and illustrated for an electronic department store. The architecture has been designed and implemented using the compositional design method for multi-agent systems DESIRE. The agents within this architecture are based on a generic information broker agent model. It is shown how the architecture can be exploited to design an intelligent Website for insurance, developed in co-operation with the software company Ordina Utopics and an insurance company.     

基于BDI的Agent合同网实现

合同网是一个用于分布式问题求解的高层通信协议,本文给出了一个扩充的合同网协议的会话策略和一个BDI精神状态形成模型,并在此基础上将BDI模型用于合同网协议,给出了实现合同同网协议的一系列BDI行为驱动规则。本文在合同网协议的招投标过程中引入了信任度、稳健度和积极程度等精神状态参数,这类参数有助于改善协作质量,从而使系统具有较好的适应性和灵活性。     

为移动代理构造一个安全运行虚环境

移动代理在其执行和迁移过程中涉及到的安全问题就是保护主机不受恶意代理的攻击,其中一个重要方面就是将由程序员的编程错误而造成的危险降到最低。这主要是通过代理程序设计语言来保证的。将代理程序限制在某个安全环境内执行－即为代理程序构造一个安全的运行虚环境为实现代理的安全性提供了基础。提出了一个有效地构造安全运行虚环境的算法。     

基于agent的交易流程

从交易agent的行为特性出发,探讨了一典型交易流程的设计和实现。先给出交易流程图,然后再探讨交易环节中安全通信机制的框架和特征,接着针对具体环节深入探讨了其中的安全通信机制。最后给出流程支撑环境和结论。     

主体命名方式AST

主体的命名和定位是移动主体中的关键技术,它的优劣影响到整个移动主体系统的性能,在分析了目前几种主体命名和定位方式之后,提出一种新的主体命名和定位的方法：Agent Shadow Tracing。这种方法将主体看成是生成它的主机的一种资源,为主体在生成它的主机上分配一个固定的界面（shadow）,在主体移动时,别的主体和程序可以通过与界面交互达到与移动主体通信的目的,这种方法避免了目前主体命名和定位方式的一些缺点,较好地解决了移动主体之间的通信问题。

Augmenting interaction and cognition using agent architectures and technology inspired by psychology and social worlds

Intelligent agents can play a pivotal role in providing both software systems and augmented interfaces, to individual users from all walks of life, to utilise the Internet 24 h a day, 7 days a week (24×7), including interaction with other users, over both wireless and broadband infrastructures. However, traditional approaches to user modelling are not adequate for this purpose, as they mainly account for a generic, approximate, idealised user. New user models are therefore required to be adaptable for each individual and flexible enough to represent the diversity of all users using information technology. Such models should be able to cover all aspects of an individual’s life—those aspects of most interest to the individual user themselves. This paper describes a novel intelligent agent architecture and methodology both called ShadowBoard, based on a complex user model drawn from analytical psychology. An equally novel software tool, called the DigitalFriend based on ShadowBoard, is also introduced. This paper illustrates how aspects of user cognition can be outsourced, using, for example, an internationalised book price quoting agent. The Locales Framework from Computer Supported Co-operative Work is then used to understand the problematic aspects of interaction involved in complex social spaces, identifying specific needs for technology intervention in such social spaces, and to understand how interactions amongst mobile users with different abilities might be technically assisted in such spaces. In this context, the single user-centred multi-agent technology demonstrated in the DigitalFriend is adapted to a multi-user system dubbed ShadowPlaces. The aim of ShadowPlaces is to outsource some of the interaction necessary, for a group of mobile individuals with different abilities to interact cooperatively and effectively in a social world, supported by wireless networks and backed by broadband Internet services. An overview of the user model, the architecture and methodology (ShadowBoard) and the resulting software tool (the DigitalFriend) is presented, and progress on ShadowPlaces—the multi-user version—is outlined.

磷酸酯类偶联剂对CaCO3／HDPE体系偶联效果的研究

研究了自制磷酸酯“W-893”偶联剂对轻质CaCO_3/HDPE的偶联效果。就力学性能(抗张强度、弯曲强度、冲击强度),流变学特性(流动曲线、表现粘度、剪切敏感性、温度敏感性、挤出胀大、压力振荡、熔体破坏)和比重测定的结果发现:“W-893”/CaCO_3/HDPE体系的冲击强度可以为HDPE(5000S)的2～3倍(325目),甚至3～4倍(1250目);弯曲强度提高33.3％,抗张强度下降2.5％,比铝酸酯、钛酸酯的偶联效果好。
