Method of Web service composition partition based on data stream constrain;

A new data envelopment analysis(DEA-Nash) model is proposed by introducing Nash constraint parameters and structuring Nash equilibrium constraint.

Hierarchical ellipse detection algorithm based on local PCA Hough transform with parameter restraint

A Study on Algorithm of Delaunay Triangulation for the Constrained Data Set and Application;

This paper presents a method isolated workflows, which separates data from tasks, by using data restriction and task restriction to ensure workflow execution correctness and alleviate the complexity of workflow, and uses the expression power of consistency constraints in a database query language (SQL) to achieve workflow concurrency control.
