The preferred sensors are radars since they have the ability to penetrate deep through dielectric barriers. Doppler radars are used to recognize signs of life by recognizing micro-Doppler signatures of human activity, such as arm swinging, breathing, and torso bending. Such movements induce different types of Doppler spectra depending on the manner in which limbs and other body parts move, which can be analyzed by several well-known time-frequency approaches, including the recently-developed empirical mode decomposition (EMD) analysis. We have developed simple models to characterize the above activities, and analyzed the Doppler signals induced using EMD. A comparison of these simulated results with actual measured data using a millimeter-wave CW radar system shows good agreement.","PeriodicalId":180836,"journal":{"name":"International Conference on Wireless Technologies for Humanitarian Relief","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130100043","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}

Such community networks provide a readily available platform for delivery of humanitarian relief services. Wireless technologies can play an important role in enabling humanitarian relief applications that strengthen these community networks by facilitating the flow of information amongst the community members. Nevertheless, given the welfare nature of the activity, these applications face some strict design constraints that emerge from the larger socio-political-economic landscape. This paper presents a systematic approach to unearth the requirements that these domains may impose on the design of wireless enabled information and communication oriented humanitarian relief services, wiHRS. We describe SEAM, a systems thinking inspired conceptual framework that provides the theoretical underpinnings of the modeling apparatus used in this paper. As an example, we demonstrate the relevance of this framework to the design of wiHRS by analyzing the economics of enhanced information flow in community networks and how this analysis can be exploited to reflect on the financial viability of such services by, say, soliciting support from financial risk management instruments like insurance schemes.","PeriodicalId":180836,"journal":{"name":"International Conference on Wireless Technologies for Humanitarian Relief","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126882433","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}

Facilitation of such services is being frequently recommended by both Government and Private agencies. The advent and deployment of 3G and above communication standards will play a major role in realizing the objective. The spread and accessibility of wireless and mobile networks may be utilized to make availability of the advices of medical expert, physically present at a state-of-art hospital to a remote patient. Similarly, the patient data or live footage on patients' current state may as well be sent to the doctor from a distant place. One of the most challenging aspects for applications deployed over 3G networks is to ensure assured QoS for data application in conjunction to live video transmission. However, these QoS provisioning need to be application-specific and at the same time, should not affect other services running at terminal equipment or mobile terminal (ME/TE). In this paper, agent based architecture has been proposed to ensure QoS for Video-Medic services. The proposed framework ensures that application specific optimizations for Video-Medic services do not deprive other concurrently executing applications over mobile terminal..","PeriodicalId":180836,"journal":{"name":"International Conference on Wireless Technologies for Humanitarian Relief","volume":"569 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116065172","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 implemented features of the application framework include - sensor data acquisition and display, network activity detection of deployed motes, over-the-air programming for software re-visioning, as well as node localization and mapping. The application framework also extends to incorporate the software defined radio based gateway deployed using GNU Radio platform and Universal Software Radio Peripheral (USRP) which enables the testbed to bridge to other heterogeneous systems.","PeriodicalId":180836,"journal":{"name":"International Conference on Wireless Technologies for Humanitarian Relief","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133185082","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}

Management of chronic illness requires a partnership of the person with the illness and the healthcare establishment in an ecosystem of information flow. Remote biosensors in a ubiquitous computing environment provided by mobile phones allows the constant participation of the person with the illness in his or her own health care by providing communications and disease indicators simultaneously and at low cost. The addition of a geographic information system allows the aggregation of individual data into a picture of the epidemiology of the illness and its control, thus facilitating regional and national health planning at low cost without compromising individual privacy. The dissemination of such a system is a complex political and social task with great potential benefit for improving individual and societal quality of life while reducing the cost burden of chronic disease.","PeriodicalId":180836,"journal":{"name":"International Conference on Wireless Technologies for Humanitarian Relief","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133044314","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}
