The model transformation from Computation Independent Model (CIM) to Platform Independent Model (PIM) level is one of the crucial and difficult points in the implementation process of model-driven Enterprise Resource Planning (ERP) system. For achieving the semantic conforming transformation between these two abstract modeling levels in Model Driven Architecture (MDA), a model transformation method based on ontology technology was proposed, which was a semi-automatic and general method. Firstly, the existing problems of model transformation from CIM level to PIM level in current studies were analyzed. Then, a model transformation framework based on ontology was built, the basic concepts relating to ontology were defined, and the whole architecture was described. After that, the transformation method was researched from two parts, the discovering of mapping rules and the occurrence of model transformation, which included the discovering technology of mapping rules based on similarity and the working principles of model transformation generator. Finally, a model transformation example was provided for validating the practicability and feasibility of proposed theories.

The mechanical errors in a mobile waveguide slot array antenna will finally influence the electromagnetic performances. Hence it is necessary to understand the relationship between them, which requires mechanical-electromagnetic analyses. The 3D models in both mechanical analysis and electromagnetic analysis are greatly different. They need a precise connection and transformation. The paper proposes an effective 3D model transformation method. From 3D geometric model to 3D mechanical model, and then to 3D electromagnetic model, the precise connection and transformation can be finished. It can be used to increase the analysis precision of a complex waveguide slot array antenna.

Using traditional methods such as perturbation theory or Galerkin approach method to analyze the dynamic response of electrostatic devices is not easy due to the complexity of the interactions between the electrostatic coupling effect, the fringing field effect, the residual stress, the nonlinear electrostatic force and squeeze-film damping effect. Accordingly, the present study proposes a new approach for analyzing the dynamic response of such devices using a hybrid numerical scheme comprising the differential transformation method and the finite difference method by pure DC or combined DC / AC loading. The validity of the proposed scheme is confirmed by comparing the results obtained for the pull-in voltage of the micro-beam with those presented in the literature derived using a variety of schemes. Overall, the results show that the hybrid numerical scheme provides a suitable means of analyzing the nonlinear dynamic behavior of a wide variety of common electrostatically-actuated microstructures.
