Large-scale object-oriented（OO） software systems have recently been found to share global network characteristics such as small world and scale free,which go beyond the scope of traditional software measurement and assessment *** measure the complexity at various levels of granularity,namely graph,class（and object） and source code,we propose a hierarchical set of metrics in terms of coupling and cohesion-the most important characteristics of software,and analyze a sample of 12 open-source OO software systems to empirically validate the *** results of the correlations between cross-level metrics indicate that the graph measures of our set complement traditional software metrics well from the viewpoint of network thinking,and provide more effective information about fault-prone classes in practice.

Differential evolution (DE) is a simple and efficient scheme for global optimization over continuous spaces. In this paper, a clustering-based differential evolution with chaotic sequences is proposed for the design of two-dimensional infinite impulse response digital filters and is compared with the previous design methods. In CCDE, one-step k-means clustering algorithm is used to get the cluster centers. These centers and chaotic sequences are used to improve the differential evolution scheme. This method utilizes the concept of the cluster of each population member. The proposed schemes balance the exploration and exploitation abilities of DE. The design problem of the 2-D IIR digital filter is reduced to a constrained minimization problem and the solution of this problem is achieved by the CCDE approach. It can provide the robust optimal solutions. The computational experiments show that the CCDE approach can obtain better results than the previous design methods.

This paper describes how to use the Unified Modeling Language (UML) to modeling software processes in medical insurance MIS, and compares UML Modeling method with classic PO(Process Oriented) Modeling method. It indicates that the whole performance of application system model described by UML is much better than the one described by PO.
