In urban environments, using an example application of environmental sensing on street corners, the benefit of active sensing, which includes monitoring and reporting of real-time data, such as calculation of passing traffic rate and measuring noise, can be easily seen. Passive information gathered from urban sensing might include sampling the air quality along a roadway for detection of road and urban pollutants. A network architecture has been developed to integrate active and passive sensor information gathered from urban environmental sensing networks. Depending on the active sensing information gathered, passive sensing information may be gathered, for integration with active sensing, and escalation for alert reporting. Using the selected illustration application of a wireless urban environmental sensor network, the correlation of information gathered in near real-time is presented and discussed.","PeriodicalId":403208,"journal":{"name":"2008 2nd Annual IEEE Systems Conference","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128256301","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 is a complementary approach for coordination between the autonomous underwater vehicles. This paper mainly describes different methods for underwater communication. One of the methods is brute force approach in which messages are broadcasted to all the communication nodes, which in turn will broadcast the acknowledgement. Issues relating to this brute force approach are time delay, number of hops, power consumption, message collision and other practical issues. These issues are discussed and solved by proposing a new method to improve efficiency of this proposed approach and its effectiveness in communication among autonomous underwater vehicles.","PeriodicalId":403208,"journal":{"name":"2008 2nd Annual IEEE Systems Conference","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129666853","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}

As DoD systems of systems are being recognized with explicit management, systems engineering and funding support, systems engineers face challenges in applying systems engineering processes to support SoS, particularly in the typical situation when the systems retain their independence. This paper describes the situation in SoS in the context of existing SoS frameworks and discusses the current DoD approach to SoS and challenges the SoS environment poses for the systems engineer at both the SoS and system levels. Finally, the paper will suggest some areas for further investigation to address key issues as systems engineering takes up the challenge of these changes in the interdependent networked environment of the future battle space.","PeriodicalId":403208,"journal":{"name":"2008 2nd Annual IEEE Systems Conference","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131555938","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 exchanges navigation data with other vessels and with coastal monitoring stations on VHF maritime mobile band. It is based on a self-organized medium access network and relies on the use of a GPS receiver to compute and transmit boat positions. To bring about such a network and ensure its reliability, the nodes must be designed with stringent requirements in mind. In this paper we propose to design and implement the link layer, and therefore the medium access process, of the AIS system. Specification and description language real time (SDL-RT) which is a real time extension of SDL is used to design the system. SDL-RT offers a hierarchical graphical tool which facilities system complexity management, functional testing capabilities and optimized code generation. The generated code is implemented and tested on a digital signal processor (DSP).","PeriodicalId":403208,"journal":{"name":"2008 2nd Annual IEEE Systems Conference","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125230475","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}

A very basic problem regarding security properties of agent-based systems is that whether a message sent by an agent is reliably received by other agents and whether the message received is regarded as reliable in the view of receivers. The problem generally depends on the trust that agents would put in the security mechanisms of the system. In order to support the analysis of various security mechanisms in agent-based systems, it is necessary to systematically investigate formal representation techniques, and provide more generic tools for the specification, and reasoning about trust theories formalizing security mechanisms in agent-based systems. In this paper, we use a temporalised belief logic to show how to establish dynamic trust theories for communication protocols. Such theories provide a foundation for reasoning about properties of agent-based systems operating in dynamic environments. We also outline a decision procedure based on model checking for verifying security properties for trust theories.","PeriodicalId":403208,"journal":{"name":"2008 2nd Annual IEEE Systems Conference","volume":"249 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115101368","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}

Throughout the world, populations are aging rapidly, which is creating unprecedented economic, social, political, and technical challenges that cannot be solved using past approaches. Healthcare today is terribly wasteful of labor, material, computer, and capital resources, and its high fatigue and error rates cause unacceptable human suffering daily. SoSE methodologies, including incremental modeling, simulation, verification, and validation can help create new healthcare enterprises that are not only more efficient and more humane, but are also more readily adapted to the endless evolution of science, society, and technology, and the equally endless and unpredictable emergent behaviors that all systems inevitably provoke.","PeriodicalId":403208,"journal":{"name":"2008 2nd Annual IEEE Systems Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129343299","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}

Vij","doi":"10.1109/SYSTEMS.2008.4519014","DOIUrl":"https://doi.org/10.1109/SYSTEMS.2008.4519014","url":null,"abstract":"Cognitive maps are cartographic illustrations of a person's internal representation of the spatial environment in which they live. All of us do form and use cognitive maps, whether in real or virtual space, to deal with and process the information contained in the surrounding environment. Cognitive maps help in visualizing the positional and location details and also the route map for reaching the destination from the current location. Quality of such visualizations directly depends on the quality of the cognitive maps. Thus a human being's spatial behavior relies upon, and is determined by the individual's cognitive map of the surrounding environment. One major deprivation in the life of visually impaired and the blind people is the access to information and visualization, as a result of which navigation and orientation ability as well as the ability to perceive surrounding environment reduces. This paper describes a technique and related experiments for acquisition of spatial knowledge (and thereby development of cognitive maps) of a building or a locality by visually impaired and the blind people through training in computer-simulated (virtual) environments. These might be places such as a school, a university campus or a shopping center. Our system allows them to navigate virtually and is able to record navigation path of participants. An algorithm is also presented for finding optimal path between places using boundary relation heuristic. Special emphasis is placed on online assessment (using various statistical measures) of cognitive maps formed by participants after walking through virtual environments. Preliminary results indicate that (1) bi-dimensional regression analysis is more useful than other methods to assess the configural relations between cognitive and actual maps and (2) most of participants were able to create precise cognitive maps after getting trained in virtual environments.","PeriodicalId":403208,"journal":{"name":"2008 2nd Annual IEEE Systems Conference","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116655451","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}
