The inlet of an IMS typically utilizes a membrane made of generic polymers such as polydimethylsiloxane or polyvinylidene fluoride. These membranes are designed to allow analytes through but protect the detector from dust and keep a controlled relative humidity and pressure. IMS signals can be enhanced using sorbent polymer membranes to concentrate vapors of interest. Specifically, in this work a strong hydrogen bond acid (HBA) sorbent polymer (HCSFA2) was synthesized to reversibly bind with hydrogen bond basic (HBB) analytes. HCSFA2 has suitable thermal stabilities but offers low viscosities above 50degC. To mitigate this problem HCSFA2 was combined with fillers to maintain the membrane's physical structure. The HCSFA2 composites were characterized using various techniques including thermogravimetric analysis, optical microscopy, inverse gas chromatography, FTIR, and differential scanning calorimetry. Additionally, data from a membrane interfaced with an ion mobility spectrometer (IMS) is described.","PeriodicalId":366416,"journal":{"name":"2008 IEEE Conference on Technologies for Homeland Security","volume":"150 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":"132756735","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}

There is a growing need to prolong their lifespan through maintenance efforts and enhance them to accommodate new and changing market requirements and governmental regulations. The majority of these systems were developed at a time when security requirements were more relaxed and not well understood, and at a time when being netted did not have the same consequences as exist today. There is a real need for retrofitting security into legacy software systems so they can operate in the current environments. However, over time, as legacy systems became larger and more complex, their design structure eroded which hinders system comprehension, compromises architectural integrity and decreases maintenance productivity. This makes the task of retrofitting security difficult and risky. Since legacy systems are a large part of our nations' critical infrastructure we must retrofit-in security in such way that the level of confidence related to security is substantially increased. This paper will discuss a standards based approach to achieving this goal.","PeriodicalId":366416,"journal":{"name":"2008 IEEE Conference on Technologies for Homeland Security","volume":"14 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120914635","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}

Interdicting these elements before they penetrate our borders and are assembled to stage attacks poses major security challenges. We describe TRANSEC, a pilot decision support system that models and helps validate assessments of maritime transfer threats and strategies for mitigating those risks. TRANSEC employs a network model that links the key entities involved in the transport of terrorists and threat-related materiel. It dynamically projects the likely impacts over time of existing and prospective security measures on interdiction effectiveness metrics at embarcation, transit, and debarkation points. The system allows alternate strategies to be assessed against scenarios based on diverse assumptions about funding and technology trends; terrorist objectives and capabilities; and program implementation results. TRANSEC also enables monitoring of strategies as they are executed, to re-validate or adjust them adaptively as environmental conditions evolve. This simulation-based methodology helps uncover security gaps and unintended program consequences in a safe and low cost virtual environment. TRANSEC thereby reduces risk and improves confidence and consistency in transfer threat security decisions.","PeriodicalId":366416,"journal":{"name":"2008 IEEE Conference on Technologies for Homeland Security","volume":"57 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":"126476384","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}

High level of FAR, bottlenecks at sensor to processing unit link levels, environment dependency and lack of targets classification and localization accuracy are drawbacks shadowing the strategic advantages of the concept. The new 3D seismic sensor for virtual border application, under development at Spider-Tech (Spider Technologies Security Ltd.), Israel, is addressing those drawbacks and paves the way to a seismic based early warning system with better performances to cost ratio than of other early-warning systems existing today. A new sensing element - an accelerometer, having low weight, small geometry and high performances, specially designed for this type of application, is used as building brick for the new sensor. The new proprietary concept combines differential acceleration measurement on each axis with a virtual single point 3D measurement. The integrated data processing hardware runs the detection, the noise cancellation, the DOA (direction of arrival) angle calculation and the target classification algorithms and has a strong impact on the amount of data transferred to the upper levels of the system. The use of the novel 3D sensor in the seismic based early- warning systems can help extend the sensor's detection range for human targets from minimal radius of 15 m to more than 30 m - depending on soil type, with detection rates exceeding 85% while maintaining an ultra low FAR (False Alarm Rate). When information from at least two sensors is combined, target localization precision can reach plusmn2 m at 15 m radius.","PeriodicalId":366416,"journal":{"name":"2008 IEEE Conference on Technologies for Homeland Security","volume":"69 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":"121956464","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}
