Abstract: The main purpose of designing an evaluation method for routing strategy is to accurately evaluate the performance of a series of routing strategies at various network loads, including under-load, full- load and even overload. Most researchers evaluate the effectiveness of a new routing strategy with the method of Order Parameter. However in this evaluating process, we find that its result distributes in a certain range of values instead of a single value, so Order Parameter introduces a considerable error, it is difficult to evaluate the performance of a routing strategy accurately in different network load with it. To solve this problem, a method--Improved Order Parameter (OOP) is proposed. This method can not only get a fixed critical value for a special network load, but also depict the transition of network load over time. According to simulation experiment, the OOP can be more objective to evaluate the performance of a routing strategy at various network load.

Abstract: One brief introduction of side OOP and TWG test are given. Comparison application of the airbag deployment simulation in LS-DYNA between Control Volume Method(CV), Arbitrary Lagrangian Eulerian Method(ALE) and Corpuscular Method(CPM) are descripted. CPM theory could describe the gas flow that is necessary for OOP(out of position) research. Three kinds of TWG tests were conducted and acceptable Hybrid Ⅲ 3YO dummy injury repeatability was achieved. The simulation used in side OOP simulation get good correlation results. Influences of many parameters in side OOP constraint system could be studied based on the simulation and test results.

Abstract: Focused on the current problems of the automated testing for electromagnetic compatibility, this paper proposes a hierarchical and modular electromagnetic compatibility software architecture based on the OOP. This paper gives the design ideas, methods and main features and develops a test automation software for electromagnetic radiation safety margin based on this architecture. Experimental results show this software improves test efficiency, accuracy and achieves the desired effect compared with the manual testing. This software also reduces the intensity of the work of the testers and has a good value in engineering.

Abstract: A CAD/CAM idea with its relation model including the analyses of braid process, yarns internal geometry and mechanical properties is proposed. An infrastructure of CAD/CAM system with platform and criterions which endure expandability is introduced. Based on the platform, some subsystems are built to accomplish various tasks such as 3D modeling, finite element analysis and braided process simulation. In order to implement the platform, parameter transferring is analyzed and an example is given. Based on the braiding process of composite, the axis direction stiffness/flexibility matrix, cell stiffness and engineering constants is acquired by the analysis of yarns and cell. At last, a proper and feasible collaborative environment and the tasks assignment is proposed. Based on the platform, an analysis instance is finished and the results are exhibited.
