Testability nonphysical verification acquires more and more attentions. While most of the traditional testability evaluation models can only describe the relationship of signals, faults and tests qualitatively, they have little quantitative information and this may cause significant deviation between verification result and the real one. So after doing research on the requirements of verification evaluation to virtual Prototypes, a testability evaluation modeling techniques was proposed based on Modelica in this work and the Function-Structure-Fault-Test-Circumstance Model was also defined and described mathematically herein. Additionally, a testability evaluation model of a data collector was built in this paper. By comparing the numerical result with that of the testability physical verification, the following conclusion can be obtained: With sufficient modeling information, testability evaluation model can be built accurately by using the method put forward in this paper.","PeriodicalId":152074,"journal":{"name":"2014 Fourth International Conference on Instrumentation and Measurement, Computer, Communication and Control","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115421174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presented the method of Mode Decomposition Based Cepstrum Spacing Measurement (MDCM) which improves the performance of the bone scatterer measurement. Compared with other techniques, MDCM approach is adaptive, empirical and takes advantage of the Intrinsic Mode Functions (IMFs) which have specific physical meanings. This technique was validated by backscattering data obtained from simulations based on two different methods, Faran cylinder model and Finite Element Method (FEM), where scatterers were defined to be equally and quasi-periodically spaced. Both the simulation results show that the first mode (IMF1) decomposed by Empirical Mode Decomposition (EMD) preserves the intrinsic feature of original data and clearly demonstrates the scatterer spacing of 0.41 mm and 0.5 mm. Then the Ensemble EMD (EEMD) based cepstrum technique was used and it shows that the interference peaks are suppressed. Besides, in addition to IMF 1, the IMF 2 also shows valuable information for MSS measurement.","PeriodicalId":152074,"journal":{"name":"2014 Fourth International Conference on Instrumentation and Measurement, Computer, Communication and Control","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121368234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, by taking the time derivatives of the Kepler orbit elements and the correction terms, the algorithm comprises close-form analysis formulas and the processing steps for directly computing a BDS satellite's instant velocity using the broadcast ephemeris is derived, and its validity is verified by test. Further, it is discussed on how the size of the differential time step affects the accuracy of the velocity results computed using the position differential algorithm. To investigate the suitable magnitudes of the differential time step, a comprehensive test is performed. In this test, several BDS satellites with different types were specially chosen and the real broadcast ephemeris was used to determine the velocity vectors both by the position differential algorithm and the direct algorithm, and the results were compared. The 12hr comparison test illustrates that the differential time step magnitude suitable for computing a BDS GEO satellite's velocity is 1s and the max residual is less than 0.0001mm/s. The differential time step suitable for a BDS MEO/IGSO Satellite is 100ms and the max residual is less than 0.001mm/s.","PeriodicalId":152074,"journal":{"name":"2014 Fourth International Conference on Instrumentation and Measurement, Computer, Communication and Control","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126937411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
