Base on the Extended Object-Oriented Petri Net, and the component evolution processes that has been proposed in our previous research, this paper applies the top-down and bottom-up strategy to stratify component models. The definition of Equivalent Model of EOOPN is given, four types of subnet Equivalent Model are analyzed and the system performance analysis methodologies corresponding to the four...
This paper studies the issue of component refinement on the bases of component evolution processes that has been proposed in authors previous research work focused on Extended Object-Oriented Petri Net. Components are refined through basic elements of software system's architectural components. The detailed idea of component refinement is discussed and a set of methods and rules relating to component...
Base on the Extended Object-Oriented Petri Net, and the component evolution processes that has been proposed in our previous research, this paper studies the issue of component refinement. Three types of component refinement under the framework of EOOPN model, namely ABP refinement, ABT refinement and Token refinement, are proposed in this paper along with their definitions and component features...
As lacking clear understanding of energy-using characteristics for devices, it is difficult to reasonably assess their consumption levels of energy. In order to solve this problem, chart-module integration theory is applied to energy consumption simulation field to design a software system that supports dynamic energy consumption simulation in this article. Firstly, the overall architecture of the...
This article analyzed IPO data of China's 561 companies in SME board and 186 companies in GEM board, and claimed that the new IPO system implemented in June 2009 provided opportunity for high-priced, high price-earnings ratio IPO. Underwriters and the former major shareholders became the beneficiaries and the largest driving force because of their profit-driven behavior. In the current external environment,...
This paper first provides the design scheme of sensors data acquisition system which mainly includes two parts: the data acquisition based on DSC (digital signal controller) and the data processing based on LabWindows/CVI. The drift error data are measured through this test. Then the drift characteristics ARMA model is identified. Based on this model, the corresponding robust filter is designed by...
