A purge-and-trap concentrator fitted with a carbotrap adsorbent tube was used to preconcentrate the accelerants from various fire residues. The resultant sample tubes were submitted to a thermal desorption unit (TDU) which was connected to a dual wide-bore capillary column GC. The identification of the accelerants was based on both a retention indices comparison and chromatogram pattern recognition. The advantages and disadvantages of this dynamic adsorption/desorption procedure were evaluated by comparison with other pretreatment procedures such as charcoal tube adsorption/CS/sub 2/ extraction and continuous steam distillation.<<ETX>>","PeriodicalId":404786,"journal":{"name":"1993 Proceedings of IEEE International Carnahan Conference on Security Technology","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128609680","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, attention is given to practical means of specifying and quantifying advanced digital system performance in the planning, design, and implementation of these systems, and to the intelligence process needed to back-stop these technologies. A unified virtual architecture is considered. It is concluded that to be effective in this area, our use of technology must be guided by a master stratagem. Globally, this mindset requires both a policy and concept of operations integration of CI (counterintelligence) and OPSEC (operations security) and the migration to a communications architecture that facilitates seamless information transfer in a fashion that protects sensitive LE (law enforcement) and IS (internal security) operations.<<ETX>>","PeriodicalId":404786,"journal":{"name":"1993 Proceedings of IEEE International Carnahan Conference on Security Technology","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127463217","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 new technology MPICS (Motion PICS) was evaluated at a Canadian penitentiary. The system uses a transputer network with a distributed image frame store to yield fast recall from many cameras of the events leading up to, at the time of, and just after the alarm. The most likely causes of the alarm are indicated on the display to assist user decision-making. This is especially useful during periods of high alarm activity when many zones may alarm in rapid succession.<<ETX>>","PeriodicalId":404786,"journal":{"name":"1993 Proceedings of IEEE International Carnahan Conference on Security Technology","volume":"67 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128975082","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}

These messages will only be readable by those users who have the appropriate read key(s). The other messages will be undecipherable. This is a generalization of the secure broadcasting problem stated by G. H. Chiou and W. T. Chen (1989) and C. C. Chang and C. H. Lin (1988). The proposed generalized secure broadcasting cryptosystem is based on Newton's interpolating polynomials and the Chinese remainder theorem. It is observed that the key management by a Central Authority is simple. In order to broadcast distinct messages to different users, one is only required to construct a polynomial and to compute a constant. To reveal a message, the authorized receiver only has to reveal his key by taking the constant modulo his identification number, evaluate the received polynomial with the obtained key, and then decrypt the resulting ciphertext by using his secret key. The sender can randomly choose any number of users who are authorized to know distinct messages within one broadcast.<<ETX>>","PeriodicalId":404786,"journal":{"name":"1993 Proceedings of IEEE International Carnahan Conference on Security Technology","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128466364","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 includes the use of RadioGuard on the perimeter of roof tops. An algorithm for solving RadioGuard detects humans moving in proximity to a distributed antenna cable by monitoring disturbances to commercial FM radio signals. By utilizing the transmissions from a number of FM stations and the use of commercial FM radio receiver integrated circuits, RadioGuard provides reliable performance at an affordable price. The unique sensing cable, a modified commercially available TV twin lead, is a key to making this possible. Product design parameters as they relate to both cost and performance are discussed.<<ETX>>","PeriodicalId":404786,"journal":{"name":"1993 Proceedings of IEEE International Carnahan Conference on Security Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128867387","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}
