In the UAV system, on account of its dynamic environment, mechanical complexity and other factors, it is difficult to avoid all potential faults. So, in order to early detect the potential fault, fault forecast is necessary so as to avoid enormous losses. As the input and output response model of UAV system is nonlinear and multi-parameters, it is need to find an appropriate way to of fault prediction for system maintenance and real-time command. Particle filters are sequential Monte Carlo methods based on point mass (or ‘particle’) representations of probability densities, which can be applied to any state-space model. Their ability to deal with nonlinear and non-Gaussian statistics makes them suitable for application to the UAV fault prediction. UAV is an extremely complex system, two important aspects of monitoring are focused on this paper: 1) Engine condition monitoring and fault prediction; 2) UAV flight track forecast. The experimental result indicates the effectiveness of this approach.","PeriodicalId":187421,"journal":{"name":"2009 IEEE AUTOTESTCON","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121141310","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}

The use of CCPM in Support Engineering initially began in the Mechanical/Electrical group in mid-2003. In late 2006, CCPM was also applied on other programs. The application of CCPM in the Mechanical/Electrical group was to aid in managing the complexity of working multiple programs simultaneously. Based on its success in reducing cost and cycle time, CCPT was applied to ATE projects to manage the complexity of the multiple subsystems being developed within one project. In a CCPM model of a project, the buffers are aggregated from individual task to provide visible safety for the entire project task network. There are two main types of buffers; Project Buffers and Feeder Buffers. The Project Buffers This paper will show how the deployment of CCPM has progressed from handling basic linear projects individually, to handling multiple linear projects, to handling large scale ATE projects with high degrees of imbedded complexity and parallel development efforts. In addition, this paper will describe the techniques developed for handling parallel development efforts, while maintaining the integrity of the CCPM project management data and will also show that the use of CCPM is completely compatible with Earned Value. Finally, this paper will describe the thirteen step process for back-chaining task networks used in CCPM produces executable project plans and it will also describe how CCPM can be used to develop program planning during the proposal phase of projects.","PeriodicalId":187421,"journal":{"name":"2009 IEEE AUTOTESTCON","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115203014","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}

In addition, comparison is made with previous studies, in particular that into RF stimulus & measurement [5]. The implementation platform consists of Rohde & Schwarz's Vector Signal Generator, Spectrum Analyser & Vector Network Analyser. The tests are defined using the Standard's Test Signal Framework (TSF); use is made of the Standard's Signal Modelling Language to validate the behaviour of the test signals; IEEE ATML Test Station is used to describe the mapping onto the test resources; an XML document is written to describe the mapping to the test resource IVI drivers; and, an IEEE 1641 defined COM interface is used access these documents. By producing a test program that conforms to the IEEE 1641 defined interfaces, it is shown that the defined tests can be validated, translated to the test platform's native IVI and executed, all using the same source.","PeriodicalId":187421,"journal":{"name":"2009 IEEE AUTOTESTCON","volume":"278 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116840146","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}

It seems that every day somebody is pushing the limits of what to expect next out of the phone we talk on, the computer we use to do our day job, the equipment our soldier are protecting us with. As electronic system technology becomes more complex, it becomes more difficult to assure customer satisfaction. Carefully planned instrumentation migration and modernization can maximize test-system efficiency, performance and quality—and provide meaningful cost savings. There are certainly risks associated with test program set (TPS) migration and modernization. The decision to forego modernization also carries a variety of risks. Ultimately, the decision to refresh outdated technology can provide meaningful cost reductions in areas such as the number of test sets, system throughput, and calibration, maintenance and repair. This paper will explore ways you can mitigate the risks of migration by applying proven success factors.","PeriodicalId":187421,"journal":{"name":"2009 IEEE AUTOTESTCON","volume":"26 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134319846","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}

On-line periodic BIST is a testing method for the detection of operational faults in digital systems. The method applies a near-minimal deterministic test sequence periodically to the circuit under test and checks the circuit responses to detect the existence of operational faults. On-line periodic BIST is characterized by full error coverage, bounded error latency, moderate space and time redundancy. In this paper, we present various techniques to minimize the error latency without sacrificing the full error coverage. These techniques are primarily based on the reordering the test vectors or the selective repetition of test vectors. Our analytical and preliminary experimental results demonstrate that our techniques lead to a significant reduction in the error latency.","PeriodicalId":187421,"journal":{"name":"2009 IEEE AUTOTESTCON","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131002293","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}
