Dietary assessment is a critical yet understudied component within the domain of recent advances in electronic health records management. The design of a system for real-time recording of food intake requires considerable research to optimize both system characteristics and data collection procedures, and rigorous validation to confirm its superiority compared to paper-based methods for self-report. We propose to demonstrate a functional prototype of a Dietary Data Recording System (DDRS), which consists of an electronic data collection device and the software and protocols necessary to support data capture and calculation of nutrient intake. A key innovative feature of the DDRS is the use of a video camera and a laser-generated grid of distances to food surfaces, which allows calculation of food volume. This prototype system is a first step in designing an overall framework to support a realistic and rigorous evaluation of whether real-time, electronic collection of dietary data is feasible, acceptable and valid for better health data management. Components demonstrated include a real-time data collection application based on the Google Android OS, a stream based data transfer and on the fly evaluation.","PeriodicalId":369430,"journal":{"name":"2011 IEEE International Conference on Pervasive Computing and Communications Workshops (PERCOM Workshops)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128884596","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 the case of the user's context history not providing suitable context information for the observed context pattern, to the best of our knowledge context prediction algorithms will fail to forecast the appropriate future context. To overcome the gap of missing context information in the user's context history, we propose the Collaborative Context Prediction (CCP) approach. CCP utilises the collaborative characteristics of existing recommendation systems of social networks. To evaluate the CCP method an experimental comparison of the proposed method against the local Alignment context predictor is carried out.","PeriodicalId":369430,"journal":{"name":"2011 IEEE International Conference on Pervasive Computing and Communications Workshops (PERCOM Workshops)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129246989","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}

Simplistic assumptions and naïve lifetime estimation techniques invariably prove to be extremely unreliable in practice, to the point that premature battery depletion notoriously affects real-world deployments. In this paper we adopt an experimental approach and employ various types of real-world batteries to determine the actual lifespan of a sensor node under common operating conditions. We present a rich set of results from an extensive experimental campaign based on the widely used TelosB platform running TinyOS. We have measured the actual node lifetime using various brands of commercial batteries as a function of different combinations of application parameters. Some of our observations match previously published results that are often neglected, while others underscore less known properties of low-power radios.","PeriodicalId":369430,"journal":{"name":"2011 IEEE International Conference on Pervasive Computing and Communications Workshops (PERCOM Workshops)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129457068","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 computer-enabled artefacts represent a new category of smart products where objects are aware of their surroundings and cable of supporting users in various tasks. However, the complex and dynamic domain of smart products is demanding for the developers, who have to deal with the requirements of context awareness. In this demonstration, we present Simulation Environment, a simulation approach that facilitates the developing of contextual applications relied on future smart product systems. Simulation Environment supports semantic modeling of context information and provides means to generate context change events and simulate sensor values. The integration with different middleware solutions provides well defined interfaces for client applications to register as listeners for the context events.","PeriodicalId":369430,"journal":{"name":"2011 IEEE International Conference on Pervasive Computing and Communications Workshops (PERCOM Workshops)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123070405","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, there is a wealth of information about individuals beyond trust voting in emerging web based social networks. Incorporating sources of evidence into trust models for social networks has not been studied to date. We explore a trust model for social networks based on Markov Random Fields, which we call MRFTrust, that allows us to incorporate sources of evidence. To allow comparative evaluation, a state-of-the-art local trust algorithm—MoleTrust—is also investigated. Experimental results of the algorithms reveal that our trust algorithm that incorporates evidence performs better in terms of coverage. It is competitive with the MoleTrust algorithm in prediction accuracy and superior when focusing on controversial users.","PeriodicalId":369430,"journal":{"name":"2011 IEEE International Conference on Pervasive Computing and Communications Workshops (PERCOM Workshops)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122860750","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}

Without the help of server infrastructures, clients usually form a mobile peer-to-peer (P2P) system as an ad-hoc network, and discover content objects by flooding query to neighboring peers. Such a flooding-based query method consumes communication energy of all relay users. Fortunately, we notice that recent emerging location-based services (LBS) have encouraged part of clients to provide their location information. Hence, in this paper, we propose a framework, called LocP2P (Location-assisted P2P), that better utilizes partial location information to provide peers a candidate list of content owners and the corresponding potential routing paths. Our evaluation results demonstrate that LocP2P can reduce the number of query flooding, and thereby save up to 50% energy consumption for content search in a mobile peer-to-peer system.","PeriodicalId":369430,"journal":{"name":"2011 IEEE International Conference on Pervasive Computing and Communications Workshops (PERCOM Workshops)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115472708","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}
