Web-Based Interactive Simulation of Weft Knitted Fabric

In order to realize parametric simulation of three- dimensional (3D) fabric structure based on web,a 3D model describing a plain knitted fabric,in which the cross- section of the yarn is circular shape and the path of the yarn is cubic B-spline curve,is proposed in this paper. With this model,the 3D simulation of the loop and of the basic structures of the knitted fabrc is realized by using Virtual Reality Modeling Language (VRML). The virtual simulation scene is suitable for network transmission with freely available VRML browsers and can be translated,scaled and rotated quite arbitrarily. By using Java and External Authoring Interface (EAI) technology,the web- based interactive simulation platform of weft knitted fabric is established. The user can input type of structures,basic fabric parameters,and yarn colors interactively to obtain a more realistic simulation result in real-time. A new approach is provided to imitate the knitted fabric 3D appearance on network.

LAYERED ARCHITECTURE FOR ASSEMBLING BUSINESS APPLICATIONS FROM DISTRIBUTED COMPONENTS

Modern business applications are generally characterized as: distributed across many processors and/or sites, access data from multiple sources and have web-based interfaces. These applications may also involve systems or processes from multiple companies or vendor provided services. The changing business environment and technologies requires that the application be agile and adoptable in short period. Component based development has recently attracted increased attention as a preferred technology for developing business applications. However, the tools and techniques for the design, implementation, management and deployment of applications based on these technologies are at a very early stage of development. This paper presents an overview of a distributed architecture for the deployment of applications based on business components. The application of the architecture in an auto insurance claim domain is briefly described. A number of open research issues have been identified.
