Nanoaprticles(Nps)-Ag/TiO2 multilayer films with different working pressures of Ag and inserted SiO2 shell layers between Ag and TiO2 were prepared by alternate magnetron sputtering. The formation of Ag nanoparticles embedded in TiO2 matrix was confirmed by the XRD and TEM results. The optical absorption peaks assigned to the surface plasmon resonance (SPR) of Ag nanoparticles were observed in the...
Software process simulation and optimization hold out the promise of improving software development process and supporting CMMI implementation. This paper first brings up a two layer process simulation model (T-PSM). The higher level is called process model which expresses the structure of the model. The lower level contains a behavior model and a computation model. The behavior model describes the...
Business-end programming can enable end-users to develop software just-in-time. Existing business programming approaches lack guidance for end-users who have little experiences for development. Meanwhile the efficiency of development is low and the correctness of application systems are difficult to guarantee. So a novel business-end programming approach based on domain expert system (DES) was proposed...
Government business model (GBM) is used to depict business processes of governments. It includes three basic models, which are process model, organization model and resource model. But these three models can not depict the collaboration relation between the infrastructure elements (including organization model elements and resource model elements) or the information flow in a government business process...
A new service-oriented visual business process modeling language VPML-S was proposed. The meta-model for VPML-S was designed by using UML class diagram, and its formal model was established on this basis. The service-oriented function provided by service element, the reuse mechanism between business processes provided by nested sub process element, the collaboration mechanism between business processes...
