A space fish-bone beam model for the main girder of cable-stayed bridges is establishedand the space combination elements of the rigid arm and cable are introduced in this paper.

In this structure,two steel tubes,two core concretes,one web and the concrete in web cavity are firstly considered as general spatial beam elements,then they are assembled into a spatial combined beam element according to the plane hypothesis and transformation matrix formed from master and slave nodes.

A study on the space cell and the triangular divide of the torus during the design of packaging structural and modeling was made.

A study on the space cell and the triangular divide of the tore was madeThe principle for showing tore with space cell and triangular devide were given as well as the data structural of the very 3-D modelThe calculation was simplifiedAnd both the ways for defining the quartuple camber on the tore and together line of comberes with the dispersion method were also presented

A thought of parallel computing is applied to IM information reversion by putting forward a parallel computing model based ontuplespace.

JavaSpaces is a Java-based implementation of tuplespace and it provides a conceptually simple but powerful solution to design and build distributed systems that are reliable, flexible and extendable.

In the web services composition framework proposed in this dissertation, agent technology and ontology theory is introduced, agent organization is served as infrastructure to web services composition, agent conversation and semantic tuplespaces are two coordination manners to coordinate web services.

By thinking of BV and ABV algorithm,taking the bit-parallelism scheme and adding the ideas of bitmap mapping and tuple space,this paper presents a new algorithm.

we present packet classification algorithm based on bitmap and tuple space.

This paper analyses distributed middleware based on tuple space model, design and application on distributed computing environment computing platform applied for heterogeneous environment, and discusses future research work.
