IE extracts entities, links (relationships) and events of interest from text. Whi le much progress has occurred in recent years in Entity and Link Extraction, Event Extraction remains one of the weakest poi nts of IE. We hypothesize that one of the reasons is the fact that there is little understanding of, and agreement about, whatconstitutes an event. Moreover, in Intelligence and Counterte rrorism environments it is extremely difficult to describe all situations of interest, making monitoring for such situations quite chalenging. We propose a formal definition of event, developed within the framework of Situation Theory, a theory of information flow developed in logic and linguistics. Besides giving a solid y et intuitive foundation, the definition can be put to practical use. We develop a classification of event types on top of our definitio n to let a user (Intelligence Analyst or other) specify events of interest, and sketch an interpreter that can use Information Extraction tools to monitor a collection of documents in order to detect whether the specified events are taking place.","PeriodicalId":366416,"journal":{"name":"2008 IEEE Conference on Technologies for Homeland Security","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131657651","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 concept of criticality - characterizing the effect of crises on the inhabitants of smart-infrastructure - is used in this regard. This paper establishes a criticality response modeling (CRM) framework to perform quantitative evaluation of criticality response. The framework can further be incorporated in any criticality-aware middleware for smart-infrastructure. An established stochastic model for criticality response is used from our previous work. The effectiveness of criticality response is measured in terms of the Manageability metric, characterized by the Q-value or qualifiedness of the response actions. The CRM is applied to fire emergencies in an envisioned smart oil & gas production platforms (OGPP). A simulation based evaluation, using CRM over OGPP, show that high manageability is achieved with - i) fast criticality detection, ii) fast response actuation, and iii) non-obliviousness to any subsequent criticality during response actuation - verifying the applicability of Q-value as the manageability metric.","PeriodicalId":366416,"journal":{"name":"2008 IEEE Conference on Technologies for Homeland Security","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121771258","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}

Vokkarane","doi":"10.1109/THS.2008.4534463","DOIUrl":"https://doi.org/10.1109/THS.2008.4534463","url":null,"abstract":"One of the fundamental purpose of sensing information is to immediately respond to any anomalies. Wireless sensor network (WSN) is a network of inexpensive, low-power nodes with embedded processors, radios, sensors, and actuators, often integrated on a single chip, to communicate with the physical world in applications, such as security and surveillance, smart classroom, monitoring of natural habitats, and medical monitoring. WSNs differ considerably from current networked and embedded systems and due to its extreme energy constraints its design requires a proper understanding of the interplay between network protocols, energy-aware design, signal-processing algorithms, and distributed programming. Though the small form-factor of sensor nodes makes them attractable for use in monitoring applications, at the same time their small size affects resources such as the energy, computational power, and storage. Therefore, improvising on the energy constraints of wireless sensor networks is crucial. We propose two base-station relocation policies that aim to minimize the energy consumed for transmitting the data to base station. Both the policies involve a mobile base station, and focus on moving the base station closer to the active sensors that detect the target. Our first policy involves having a mobile base station and relocating it to the geometric centroid of all the sensors detecting the target. This approach significantly reduces the energy overhead required for transmitting data from the sensors to the base station. Our second policy for performing network lifetime optimization is to move the base station to geometric centroid of the base station locations obtained over several time periods. However, in each case, moving the base station at each time period involves a considerable overhead and therefore we observe the effects of moving the base station after a specific number of time periods as opposed to moving after every time period. We evaluate the network lifetime performance of these two proposed policies over different network scenarios.","PeriodicalId":366416,"journal":{"name":"2008 IEEE Conference on Technologies for Homeland Security","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132232220","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}

An integral component of such analyzers is the gas chromatographic (GC) column which is used for separations of an injected mixture based on the relative sorption of the various analytes in the carrier gas by the stationary phase. In this interim report, we describe our efforts in the design and development of a microfabricated GC column for the trace detection of hazardous chemicals. Specifically, in this work an optimized serpentine layout with a circular cross- sectional profile has been microfabricated. In this work, computational fluid dynamic (CFD) modeling has been employed as a method to aid in the GC column design optimization. Selectivity to hazardous hydrogen bond basic (HBB) analytes (e.g. TNT, GB, VX) was achieved by using an NRL developed hydrogen bond acid (HBA) sorbent polymer HCSFA2 as the stationary phase. HCSFA2 offers a higher partition coefficient than the more commonly used polysiloxanes.","PeriodicalId":366416,"journal":{"name":"2008 IEEE Conference on Technologies for Homeland Security","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124911330","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}
