Many equipment parts can be modeled individually for their operational reliability performance due to physical constraints. Reliability has traditionally been assessed from physical attacks that result in failures; however, in real-world analysis, there are cases of non-physical attacks. A survivability analysis is an aggregate of the system-level operational sustainability over the reliability of all the components. With the information age, many equipment parts are “intelligent” that include sophisticated reasoning methods that are subject to non-physical cyber attacks. Developing a model that incorporates both the physical and non-physical attacks for reliability and survivability is important for determining system-level effectiveness. For sustained operations, we need to incorporate information fusion over physical and non-physical (e.g. cyber attacks) failures to determine a system's reliability and survivability. In this paper, we develop a method of fusing reliability estimates in both continuous (component model) and discrete analysis (component attack model) for a component survivability analysis.","PeriodicalId":352567,"journal":{"name":"2012 IEEE National Aerospace and Electronics Conference (NAECON)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133876829","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}

Current research at AFIT includes signal processing techniques for adaptive wideband digital beamforming. To support the research, with the help of engineers at AFRL, wideband data was collected using the MCWESS array. The signals collected were received from three different, spatially separated, bandlimited, thermal noise sources. The noise sources have the wide bandwidth desired to support wideband digital beamforming (DBF) research. When the resulting data from the receiver did not correlate with the transmitted noise signal as expected, a closer examination of the set hardware processing done on the signal revealed the signal's true nature. This paper outlines the systematic process followed to determine the actual content of the data, shows that direction of arrival (DOA) estimation is possible when using wideband beamforming techniques even on only a partial signal spectrum, and demonstrates wideband beamforming on measured data using a time reversal beamforming algorithm developed by AFRL.","PeriodicalId":352567,"journal":{"name":"2012 IEEE National Aerospace and Electronics Conference (NAECON)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121418915","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 has made the task of reverse engineering software an increasingly necessary and critical skill. Software systems are regarded as the most complex of human designed technologies. Software can be difficult to understand when the source code is provided, but a reverse engineer is restricted to machine code and often intentionally obscured machine code. This makes reverse engineering an extreme technical challenge. This work examines the reverse engineer's cognitive task as abductive reasoning. Abductive reasoning has received significant theoretical attention in the last decade resulting in a broader account of abduction types and methods. Abduction, as the only generative means of inference is essential to hard diagnostic tasks and scientific exploration that require non-deductive and non-inductive hypothesis generation. In particular, we explore manipulative abduction and meta-diagrammatic abduction employed by a reverse engineer to counter falsification of a hypotheses and surprise. With this basis, we are studying the work of reverse engineering with the dual goals of understanding the task and looking at ways AI systems can be constructed to augment reverse engineering. Process philosophy principles of panexperientialism and consciousness are used to form a critique of current AI approaches and some tenants of a novel abductive AI framework are justified.","PeriodicalId":352567,"journal":{"name":"2012 IEEE National Aerospace and Electronics Conference (NAECON)","volume":"345 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122838187","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}
