报告题目: E-Science环境下知识协同的关键技术
随着互联网技术的应用发展,E-Science将是未来科学活动开展的主要形式。一般而言,科学活动往往对应知识密集性环境下的科学创新过程,因此,基于Web技术的E-Science活动中的科学协作,本质上是一个基于知识交互和知识再生的知识协同过程。这种动态环境下的知识协同和过程交互,在理论和技术方面给传统的知识管理领域提出了新的命题和应用挑战。知识流管理系统、认知协作、动态知识定位、虚拟组织的安全管理、知识本体的动态演变及智能跟踪等关键技术成为E-Science下支持科学创新的关键技术。而在传统的知识管理和流程管理的基础上,对内涵概念下的知识流逻辑和外延概念下的工作流逻辑进行一体化分析和研究,对E-Science的有效开展尤其具有重要的理论和应用价值。

A binary-light projection mechanism for 3D reconstruction for microscopic device is proposed. Our mechanism consists of only a single light source, allowing a binary pattern to be projected to the measured scene.  And a camera is used to capture image of the illuminated scene.  With this design, the mechanism has a much reduced system size that makes it suitable for inspection in the sem
iconductor industry. The illuminated pattern is varied by having the binary grating shifted in space, and in every shifting a separate image of the illuminated surface is taken.  This way, each position on the surface is attached with a unique string of binary code over the sequence of captured images, allowing exact correspondence between the binary pattern, image data and subsequently
3D determination. We also address how the grating and its spatial shifting, can be designed optimally for minimizing this image number for faster inspection speed.

4.申富饶    博士、副教授     南京大学
报告题目:自组织增量学习神经网络及其应用
自组织增量学习神经网络作为一种非监督学习方法,试图解决对输入数据的拓扑表示及聚类分析问题。在对输入数据没有任何先验知识的前提下,这一方法能够自动学习表示输入数据所需要的神经节点个数,自动检测输入数据中所包含聚类的数目,能够实现实时的增量学习,并且能在一定程度上消除输入数据中的噪声所带来的影响。本报告介绍自组织增量学习神经网络的设计背景、具体算法,以及其在模式识别、图像压缩、类人机器人等方面的应用。报告还将探讨对自组织增量学习神经网络的改进,以及如何将其扩展到监督学习和半监督学习等方面。

7.谭学厚     教授              日本东海大学
        报告题目:计算几何学
This talk mainly consists of two parts. The first part gives a brief of review of Computational Geometry.Computational geometry emerged from the field of algorithms design and analysis in the late 1970s. The success of the field as a research discipline can be explained from the beauty of the problems studied and the solutions obtained,and by many application domains -- computer graphics,CAD/CAM, geographic information system (GIS), robotics and others-- in which geometric algorithms plays a fundamental role. Another part of the talk contributes to recent results of my research. The most new results and paradigms developed for the well-known Art Gallery, watchman route and polygon search problems will be presented. The Art Gallery problem is to find a set of point guards such that a given polygon (the planar graph of art gallery) can be monitored by guards, while the watchman route problem is to find a route of shortest le
ngth such that every interior point of the given polygon is visible from at least one point on the route. The polygon search problem is to design a search schedule for a searcher to catch or find a moving target within the given region. (The target can move arbitrarily faster than the searcher.)  Much attention has recently been devoted to these problem, as they deal with not only visibility but also metric information and motion planning.

报告题目: Security in a Mobile Agent Based DDM Infrastructure
Mobile agent technology offers a new approach to mining information from data sources distributed over the Internet. However, the potential benefits of mobile agents must be weighted against the real security threats. An agent based Distributed Data Mining (DDM) system must cope with exposed data services and insecure communication channels in the Internet to protect the privacy, integrity and availability of agents and distributed resources. In this paper, we present the design of a mobile agent infrastructure for DDM applications and discuss the implementation of security mechanism that has been effectively integrated with the mobile agent virtual machine.
