These network prototypes, i.e., generalized honeycomb torus (GHT) networks, spider-web (SW) networks, can offer both nodes' and edges' fault-tolerance and a processing order to help the network management. The SW network can also be used as a main skeleton to combine paths' SCADA networks into an area SCADA network, which can have greater response capability. Cellular wireless telecommunications can be networked as the spider-web network to promote communication quality. SW(6,n) can optimally offer dual-pair mutually independent hamiltonian paths (MIHP) for any pair of bipartite nodes, so that information transmitted in a specific route can be assigned special meanings like the hint motion between the pitcher and the catcher in the baseball game, cooperatively with the mechanism of dynamic authentication/authorization. Furthermore, because routes of signal transmission can be specifically arranged, the impact of environmental factors related to multipath effects can be calculated to promote transmission quality. The proof of such MIHP properties is introduced by combinatorial graph patterns, logical rules, and mathematical rules in this article.","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":"131110060","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}

It appears possible to measure the Doppler frequency shift caused by radar impinging on blood pumped by the heart to infer the presence of a human in situations where other sensors cannot. This work is applicable to perimeter defense. The relation between the Doppler frequency shift and the pumping action of the heart was modeled mathematically. There is increasing interest in sending electromagnetic signals into the human body, not only for physical security but also for medical reasons [2] To estimate the detection range, propagation of a radar signal through the body is modeled. Input signal is dissipated primarily by scattering at organ interfaces, and attenuation in each organ. Scattering is caused by differences in the index of refraction at each interface. Scattering starts at the air-skin interface. In principal, the approach is valid for many radar frequencies, but high frequencies (GHz) are preferred. However, at these frequencies, significant signal attenuation is expected. Compromise frequencies are therefore being examined. Several hundred MHz might be a good alternative. In addition to examining different frequencies, different signal paths are being examined. Since the radar scans, its signal will enter at different parts of the body and therefore follow different paths, each of which will have a different attenuation. Body parts with expected low and high attenuations have been identified.","PeriodicalId":366416,"journal":{"name":"2008 IEEE Conference on Technologies for Homeland Security","volume":"115 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":"133740278","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}

However, local jurisdictions and states throughout the Nation find it difficult to share data and implement processes that span the different systems and organizations responsible for unified incident response. For example, adjacent counties often lack the means of sharing a common situational view of an evolving incident and their responses. Emerging internet technologies are key enablers for improving the timeliness and effectiveness of this unified response. This paper describes an ongoing initiative sponsored by the DHS, Science & Technology Directorate as part of the Regional Technology Initiative (RTT) that is employing EDXL, XMPP, Web Services and other advanced information technologies to interconnect cooperating EOCs in real time to improve their situational awareness and assist in coordinating their unified incident response. The paper discusses the architecture and technology incorporated in the framework, shows details of a demonstration of the system in the Seattle region, and discusses the significant advantages identified by the participating jurisdictions to date.","PeriodicalId":366416,"journal":{"name":"2008 IEEE Conference on Technologies for Homeland Security","volume":"60 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":"134253305","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}

Situation awareness is the knowledge of the state and physical location of people, objects and terrain within an area of interest. First responder operations can be quite complex, involving the coordination of and collaboration among teams distributed over large areas. Adding to this complexity is the use of heterogeneous networks with diverse radios, traffic flows and applications. This paper describes some initial results using distributed constraint optimization (DCOP) techniques to facilitate situation awareness for first responders. A brief background on DCOP is presented, along with how DCOP can be applied to enable situation awareness. An example demonstrating the application of DCOP algorithms to a particular situation awareness problem is presented. Finally, some critical issues that arise when utilizing DCOP are described, along with some approaches to addressing these issues. By integrating these DCOP techniques with situation awareness tools, we believe that many of the information distribution, interoperability, and networking difficulties faced in the first responder environment can be overcome.","PeriodicalId":366416,"journal":{"name":"2008 IEEE Conference on Technologies for Homeland Security","volume":"34 Suppl 2 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":"123466266","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 GPGC is a k-digital parametric sequence suitable for any base, n. It is also called the (n, k, p)-gray code where p is a parameter that allows the users to change the distance to yield different gray code sequences. The base n and parameter p as security keys have many options to make the encrypted multimedia difficult to decode. This allows the encrypted objects to be protected with high levels of security. The experimental results verify that the presented algorithms are lossless approaches and good at partial multimedia encryption. A method of measuring the percentage of image encryption is introduced and the measure results are also provided to quantify the encryption performance. Experiments demonstrate that the algorithms show good performance for the common attacks. Due to the low complexity of the algorithms, they are also suitable for real-time applications. The principles behind the presented solutions may be applied to various image, audio, and video systems.","PeriodicalId":366416,"journal":{"name":"2008 IEEE Conference on Technologies for Homeland Security","volume":"42 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":"129473427","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}

Acoustic sound of running vehicles is analyzed. Motivated by mammalian auditory cortex studies, the proposed detector processes both spectral and temporal components of input data. With the exact acoustic signature being unknown, a nonlinear Hebbian learning (NHL), one basic and appealing neural learning function found in human brain, is employed for unsupervised learning. This learning rule extracts representative independent features from the spectro-temporal ones and to reduce the dimensionality of the feature space. During learning, synaptic weights between input and output neurons are adaptively learned. Simulation results show that the proposed system can accurately extract critical features from original input data, and can achieve better performance under noisy environments than its counterparts. Additive white Gaussian noise and colored human vowel noise are mixed with vehicle sounds. For any vehicle recognition, the proposed system decreases the error rate to 3% with improvement 21 ~ 34% at signal-to-noise ratio (SNR)= 0 dB, and functions efficiently with error rate 7 ~ 8% at low SNR=-6 dB when its counterparts cannot work properly at this situation. Next for identifying four types of vehicles, the proposed method has workable performance 60 ~ 85% at low SNR= 0 dB and robust performance 80 ~ 100% at SNR= 5,10 dB.","PeriodicalId":366416,"journal":{"name":"2008 IEEE Conference on Technologies for Homeland Security","volume":"2 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":"126402594","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}

Initially developed as a stationary fixed technology, this project involves receiving this broadcast in a mobile environment. This one-way transmission allows the datacast receiver to decouple data packets at a rate of up to 2.5 Mbps. Utilizing these data rates, various real-time applications can play a major role in placing information in the field where the existing low-speed data transmission methods in use today cannot. Researchers at the University of New Hampshire have already reported in various papers the successes achieved in datacasting in the mobile environment, an implementation that the original developers of datacasting had not intended. The introduction of two-way communication using multiple channels coordinated with datacasting has allowed the datacasting system to achieve real-time, asymmetric broadband communication in the mobile environment that is both cost-effective and viable for delivering critical data to the field in a timely and reliable fashion. This paper explains the technical concepts jointly engineered to deliver the two-way datacasting model, as well as highlights the results of prototype applications and devices installed in a mobile environment.
