Efficient transceiver design requires in-depth understanding of the propagation media which in this case is the human body surface. The results of the few measurement experiments in recent publications point to varying conclusions in the derived parameters of the channel model. As obtaining large amount of data for many scenarios and use-cases is difficult for this channel, a detailed simulation platform can be extremely beneficial in highlighting the propagation behavior of the body surface and determining the best scenarios for limited physical measurements. In this paper, an immersive visualization environment is presented, which is used as a scientific instrument that gives us the ability to observe three-dimensional RF propagation from wearable medical sensors around a human body. We have used this virtual environment to further study UWB channels over the surface of a human body. Parameters of a simple statistical path-loss model and their sensitivity to frequency and the location of the sensors on the body are discussed.","PeriodicalId":273041,"journal":{"name":"2009 2nd International Symposium on Applied Sciences in Biomedical and Communication Technologies","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123698024","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, the image datasets acquired from LSCEM are generally with low z-depth resolution, which causes artifacts in volume rendering. Intermediate data between consecutive images needs to be generated. One common solution uses trilinear interpolation which more or less reduces the artifacts, but blocky artifacts are clearly visible especially in the areas of low spatial resolution. The current shape-based interpolation techniques cannot effectively remove such artifacts since they rely on the hard classification for identification of shape features. At the same time, the higher order interpolation schemes like cubic b-spline interpolation take much time to process the slices. In this paper, we propose a novel GPU-based surface oriented inter-slice directional interpolation algorithm to recover the missing information and thus minimize the interpolation artifacts. Our algorithm enjoys full floating point precision offered by the modern GPU to enhance the visualization result. Experimental results on several datasets clearly demonstrate the effectiveness of the new method.","PeriodicalId":273041,"journal":{"name":"2009 2nd International Symposium on Applied Sciences in Biomedical and Communication Technologies","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121502565","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}

Besides other characteristics, storage capabilities of individual sensor nodes have to be considered as this might be very small compared to the collected sensor data. The temporal availability of sink nodes or the importance of collected data are not equal for all nodes and, therefore, demand storage of the generated data locally for later retrieval. Furthermore, data items (detected events) may be collected at different rates, which can lead to hotspot-like storage requirements. In this paper, we introduce a data-centric cooperative storage mechanism for wireless senor networks. Our approach is based on Virtual Cord Protocol (VCP), a virtual relative position based efficient routing protocol that also provides means for data management, e.g. insert, get, delete, and replicate, as known from typical Distributed Hash Table (DHT) services. Data items are distributed deterministically over several nodes in the same vicinity. Thus, storing and retrieving data items typically require communication with local nodes. To maintain information about stored information, we use a bloom filter to track the nodes that are storing particular items.","PeriodicalId":273041,"journal":{"name":"2009 2nd International Symposium on Applied Sciences in Biomedical and Communication Technologies","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121584475","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}
