Activity-Directed Synthesis: A Flexible Approach for Lead Generation

Activity-directed synthesis (ADS) is a structure-blind, functional-driven molecular discovery approach. In this Concept, four case studies highlight the general applicability of ADS and showcase its flexibility to support different medicinal chemistry strategies. ADS deliberately harnesses reactions with multiple possible outcomes, and allows many chemotypes to be evaluated in parallel. Resources are focused on bioactive molecules, which emerge in tandem with associated synthetic routes. Some of the future challenges for ADS are highlighted, including the realisation of an autonomous molecular discovery platform. The prospects for ADS to become a mainstream lead generation approach are discussed.

A resource broker with an efficient network information model on grid environments

This paper describes a resource broker whose main function is to match available resources to user needs. The resource broker provides a uniform interface for accessing available and appropriate resources via user credentials. We also focus on providing approximate measurement models for network-related information using NWS for future scheduling and benchmarking. We first propose a network measurement model for gathering network-related information (including bandwidth, latency, forecasting, error rates, etc.) without generating excessive system overhead. Second, we constructed a grid platform using Globus Toolkit that integrates the resources of five schools in Taichung integrated grid environment resources (TIGER). The resource broker runs on top of TIGER. Therefore, it provides security and current information about available resources and serves as a link to the diverse systems available in the Grid.

A Scalable Toolkit for Designing Multimedia Authoring Environments

This paper introduces Kaomi, a scalable toolkit for designing authoring environments of multimedia documents. The underlying concept is to provide the designer of multimedia applications with a fast method to get an authoring system based on a set of synchronized views (the presentation view for displaying the document, the scenario view for showing the temporal organization of the document, ...) so that each view is the support of editing actions. Kaomi is flexible enough to support a variety of multimedia documents declarative formats. It is indeed a scalable toolkit since it provides facilities for extending and/or for modifying the resulting authoring environment. In addition, cross-platform portability is provided which allows operation in the heterogenous Internet environment. The use of Kaomi is mainly described through the design of two authoring environments: one for authoring a sub-set of the Smil standard of the W3C and the other one for Madeus, a constraint based multimedia language.     

Labview在HT-7极向场电源监控系统中的应用

为满足核聚变装置HT-7极向场电源控制系统的要求,利用Labview编程环境设计了状态监控界面。监控界面实现实时、可靠的监控极向场电源状态,并通过ODBC接口与数据库连接,实现实验过程回放。本文简述了状态监控界面的构造与实现。多次实验表明在Labview环境下利用UDP协议、LabSQL工具包实现实时通信和过程回放,是可行、可靠而高效的。     

支持协同的3维轻量化模型与圈阅工具的研究

为提高3维模型的传输效率和协同设计中的数据保密性,定义了一种支持协同的3维轻量化数据结构,引入了轻量化装配模型和轻量化零件模型,其中轻量化装配模型记录了模型的产品结构关系和各零件的装配位置,轻量化零件模型记录了模型的非精确显示数据和支持模型测量的精确几何数据及其关联。因为过滤原始3维模型中的非几何信息,轻量化模型的数据量约为原始模型的1／20。在系统实现方面,给出了3维轻量化工具的体系结构,研究了3维模型轻量化组件、可视化浏览器组件和可视化协同组件的开发。最后,在某汽车制造企业的产品数据管理系统中进行了实施,提高了3维环境下的协同设计效率。     

空间相关MC算法的VTK实现

移动立方体是面绘制的经典算法,但要求对所有空间所有体素进行处理,执行效率不高.通过对空间相关性进行研究,即六面体体素如果与等值面相交,则等值面一定会在该六面体的6个面的方面延续,对标准的MC算法进行改进,只处理那些与等值面相交的六面体体素.可视化工具包封装了许多常用的可视化算法,为研究人员提供了极大的便利.通过空间相关性,对VTK中已有库函数vtkMarchingCubes进行改进,提高了原有算法的执行速度,同时又扩充了VTK已有的类.
