基于保护分散式抽象方法的可扩展操作系统设计

为了提供高性能和柔性，操作系统内核应该只保留最小的功能，今天的操作系统大而低效，更缺乏柔性，我们提出了保护分散式操作系统抽象方法，集成了分散式操作系统抽象和保护抽象的方法，这种新的安全方式在分散式抽象系统里共享用户级的抽象，能够使非特权，不信任的任务在运行时定义并安全的共享生成的抽象，它在对相同的抽象重复调用时，通过消除上下文切换的需求和对通常情况进行优化，可获得较好的柔性，保护分散式抽象的设计强调简单并正确性证明，易于理解和使用，文章介绍了保护分散式操作系统抽象方法，并运用该方法开发了一个基于共享库的原型操作系统－ExLinux/LibOS.

Artificial neural networks for coordination and control: The portability of experiential representations

It is time to locate connectionist representation theory in the new wave of robotics research. The utility of representations developed in artificial neural networks (ANNs) during learning has been demonstrated in cognitive science research since the 1980s. The research reported here puts learned representations to work in a decentered control task, the disembodied arm problem, in which a mobile robot operates an arm fixed to a table to pick up objects. There is no physical linkage between the arm and the robot and so the robot's point of view must be decentered. This is done by developing a modular Artificial Neural Net system in three stages: (i) a classifier net is trained with laser scan data to output transformationally invariant position classes; (ii) an arm net is trained for picking up objects; (iii) an inter net is trained to communicate and coordinate the sensing and acting. The completed system is shown to create new nonsymbolic transformationally invariant representations in order to perform the effective generalization of decentered viewpoints.

色彩心理效应模型在人性化Web导购系统中的搭建与应用

人性化、个性化系统是现代Web商务系统的一个发展趋势,也是人工心理的一个研究方向。本文以服装选购系统为例,对人类情感的重要影响因素之一——色彩心理效应进行了进一步的深入研究。文中首次使用人工神经网络对色彩带来的膨胀紧缩感的心理效应进行数学建模,并且在服装导购系统中进行应用算法的设计和实施,从而实现了一种心理效应由感性描述到理性模型的转化,同时也使人性化、个性化智能系统的理念得到进一步完善。实验结果表明此数学模型能够较好的模拟色彩给人带来的膨胀紧缩感,在系统中的应用效果也收到了用户的好评。     

An immune oriented multi-agent system for biological image processing

In this article, we present a parallel image processing system based on the concept of reactive agents. Our system lies in the oRis language, which allows to describe finely and simply the agents’ behaviors to detect image features. We also present a method of segmentation using a multi-agent system, and two biological applications made with oRis. The stopping of this multi-agent system is implemented through a technique issued from immunology: the apoptosis.     

Ethical issues concerning expert systems' applications in education

This article traces the connection between expert systems used as consultants in medicine and their design for instructional purposes in education. It is suggested that there are important differences between these applications. Recognizing these differences leads to the view that the development of intelligent computer-assisted instructions (ICAI) should be guided by empirical research into social/psychological consequences and by ethical inquiries into the acceptability of those consequences. Three proposals are put forward: (1) that the pedagogical role of intelligent CAI be clarified, (2) that forms of intelligent CAI be developed that aim primarily at refining rather than replacing human judgements, and (3) that ICAI research and development projects contain components which address ethical and social/psychological components and which are equitably-funded, integral parts of the overall development effort.This work was supported in part by funds from the Foundation of the University of North Carolina at Charlotte and from the State of North Carolina. An earlier version of this paper was read at the Human Dimension in Artificial Intelligence Symposium held at the University of Kentucky (April 1988).
