Current work centers on physical evidence from a crime scene; however, what is presented is a computational framework that expands to the cyber world. Part of the project's foundation is based on Barwise's situation theory because it joins semantics for utterances and accounts of perceptions. Situations both support items of information and carry information about other situations. Specifically, an utterance situation contains information about a described situation. We provide an account of the support for an identity judgment (in an id-situation) that essentially builds cases (aligned to legal cases) called id-cases, because significant cases of identity can lead to various situations that impact the value of evidence. Our framework includes a situation ontology, upon which an id-situation ontology is built. While focusing on physical evidence, we also developed a physical biometrics ontology, which the physical features ontology supports. Additionally, there is a law enforcement ontology and several supporting stubs. We show how a specific case is encoded in RDF in alignment with our ontologies, and complement our id-situation ontology with SWRL rules to infer a culprit in a crime scene.","PeriodicalId":368197,"journal":{"name":"SoutheastCon 2017","volume":"298 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124269523","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 shift has presented many new challenges to the robotic research community. Development of novel robot bases, such as TurtleBot, in concert with the widespread use of robotic frameworks, such as Robot Operating System and MyRobotlab, has given researchers indispensable tools that allows for rapid development and deployment of new localization and mapping techniques. The goal of these new robot bases and frameworks is to ensure that progression in research is not hindered by the burden of lower abstractions, such as sensory setup or drive mechanisms and mechanics, but rather allows the researcher to focus on the complexity of executing higher level algorithms. This paper presents research on integrating the National Instruments DaNI 2.0 robot into the growing group of robot operating system ready mobile robot platforms. This paper presents the programming and developmental process of enabling the DaNI 2.0 robot to operate within the Robot Operating System framework and highlights the chief characteristics that separate the DaNI 2.0 from current Robot Operating System enabled robotic platforms.","PeriodicalId":368197,"journal":{"name":"SoutheastCon 2017","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126041922","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 power system model used for this study is the IEEE 21 Bus System. Each system, one powered solely by the diesel powered synchronous generators (DPSGs), and the other powered by both VSWTs and a DPSG, were tested under different conditions including a three phase fault, line outage/break, and load changes. To be able to analyze and simulate these conditions the Power System Analysis Toolbox (PSAT) was used along with Matlab. This paper will begin by giving a brief introduction about variable speed wind turbines. Also, the advantages and disadvantages using wind turbines in the power grid will be discussed. The introduction will conclude by comparing VSWTs to their counterpart, constant speed wind turbines. Many conclusions could be drawn from the tested conditions stated above. When the system with VSWTs was faulted, it resembled the behavior of the diesel generator system. However, when a line outage was applied to the system with VSWTs, it did not behave as expected like the diesel generator system did. Also, when a load is dropped, the generator bus voltage tends to rise.","PeriodicalId":368197,"journal":{"name":"SoutheastCon 2017","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123677491","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 requires estimation of the best rotational parameter ‘a’ to rotate the signal to a new domain along an axis ‘ta’ for filtering. The value of ‘a’ is usually chosen to give the minimum mean-square error (MMSE) between the desired SOI and its estimate. Recently, a technique was presented that uses repeated MMSE-FrFT filtering. This is done with a training sequence using mean-square error (MSE) as the metric by which to compute ‘a’ at each stage. This simple approach improves performance over conventional single stage MMSE-FrFT methods or methods based solely on filtering in frequency using an FFT. In this paper we apply repeated reduced rank adaptive filtering using a multistage Wiener filter (MWF). We show that the proposed MMSE-MWF-FrFT repeated filtering method significantly reduces the MSE over the repeated MMSE-FrFT method typically with just L = 1 or 2 stages and a nominal filter rank, D = 5, vs. L = 3 for MMSE. This is demonstrated by simulation using non-stationary channels as well as two types of non-stationary interference: chirp and Gaussian signals, at signal-to-noise ratios (SNRs) as low as 0 dB and carrier-to-noise ratios (CIRs) also down to 0 dB. Reduction in MSE from 0.001 to 10−4 or 10−5, or lower, is observed.","PeriodicalId":368197,"journal":{"name":"SoutheastCon 2017","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129518870","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}
