Rate allocation within this context is essential to the overall performance of a streaming system due to the limitation of wireless network resource. Optimizing rate allocation in wireless P2P streaming poses us the twofold challenge: the data flow rates are not only constrained by P2P overlay uplink capacity, but subject to the resource sharing mechanism of wireless networks. In this paper, we propose a utility-based rate allocation framework to optimize the flow rates in wireless P2P streaming systems. Our optimization framework involves both P2P overlay constraint and wireless channel sharing constraint. We propose a channel-aware approach to address the modeling of wireless channel sharing patterns. We then proceed to design a distributed double pricing algorithm to solve the optimization problem. Experimental results validate that our algorithm can achieve convergence of data flow rate allocation and optimality of network throughput.","PeriodicalId":426543,"journal":{"name":"2011 International Conference on Collaboration Technologies and Systems (CTS)","volume":"204 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134130171","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 more users enter information, the more heterogeneous the structure of information becomes. This proliferation of the schema has a significantly negative impact on the performance of querying facilities as structured, unified access of data is no longer possible. In this paper we present the Snoopy Concept, a novel approach for collaborative, semistructured information systems within an online environment. It deals with structure heterogeneity by incorporating the user in the alignment process of data already during the insertion. This is accomplished by providing the users with useful recommendations how to structure information. Furthermore, the system encourages users to enter more information as it points users to missing bits of information.","PeriodicalId":426543,"journal":{"name":"2011 International Conference on Collaboration Technologies and Systems (CTS)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133631468","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}

Electronic collaborations have been used to enable teams to collaborate dispersed or virtually using the web. Virtual collaboration and facilitation are widespread in organizations. However, delivering appropriate electronic or virtual facilitation is a complicated task to achieve and hence the evaluation of these services is a challenge. The paper delivers an assessment framework to address the evaluation of virtual facilitation services and describes the use of the framework in the field. The framework is structured in a way to map the facilitation service goals into evaluation objectives, metrics and measurements. The framework consists of a structure and a process which facilitators use to apply the framework to alternative scenarios. Finally, the framework is evaluated by experts in the field.","PeriodicalId":426543,"journal":{"name":"2011 International Conference on Collaboration Technologies and Systems (CTS)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133485861","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}

Like most current human activities, it already comprises an existing pattern of co-ordination based on technology, namely the mobile phone. It is clearly a limited technology for the purpose of supporting swimming, biking and running, such as in our case of triathlon racing. Can we identify an alternative, dedicated and equally good technology for most athletes and race conditions? In an event that comprises events as diverse as swimming, cycling and running, will not the athlete then be faced with another challenge of juggling devices in addition to multifarious athletic skills? In ubiquitous services development, another big challenge is to furnish a system with multiple stakeholder benefits, i.e., which is helpful to the athletes as well as their support team, and the crew who organizes the event and the pertaining community at large. Our objective in this paper is to provide the background to make this possible, through describing the use situations in detail, from which new requirements may originate. Our paper, in this respect, is a starting point in the process of outlining one possible “killer app” for ubiquitous communication services.","PeriodicalId":426543,"journal":{"name":"2011 International Conference on Collaboration Technologies and Systems (CTS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115483450","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}

Their pictorial characters assist visualizing the structure of text to become more understandable beyond vocabulary obstacle. In this paper we are proposing a Knowledge Engineering (KM) based iconic representation approach. We assume that these systematic icons improve collective knowledge management. Meanwhile, text (constructed under our knowledge management model - Hypertopic) helps to reduce the diversity of graphical understanding belonging to different users. This “position paper” also prepares to demonstrate our hypothesis by an “iconic social tagging” experiment which is to be accomplished in 2011 with UTT students. We describe the “socio semantic web” information portal involved in this project, and a part of the icons already designed for this experiment in Sustainability field. We have reviewed existing theoretical works on icons from various origins, which can be used to lay the foundation of robust “icons systems”.","PeriodicalId":426543,"journal":{"name":"2011 International Conference on Collaboration Technologies and Systems (CTS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127927401","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}

Even though telehealth solution can be potentially effective in such a scenario, both the age factor and often the cost of the systems hamper the diffusion of telehealth systems. KeepInTouch is a low cost system for telehomecare conceived for the daily off-line monitoring of diabetic and cardiac patients. It exploits a mixed approach offering a simple TV-based front-end from the patient side, and a web-based one from the physician side. The web-based approach enables the authorized medical professionals to access the patient data from the web, exchanging useful information and providing textual feedback to the patient, all within the system interface. The patient's front-end is based on the Digital Video Broadcasting Terrestrial (DVB-T) technology, exploiting an acquisition unit connected to the patient's certified biomedical devices (sphygmomanometer, glucometer, body weight scale) and with the interactive DVB-T set-top box in order to provide a user-friendly interface on the TV for people not accustomed with computers. The system is going to be used for a first clinical trial in Italy.","PeriodicalId":426543,"journal":{"name":"2011 International Conference on Collaboration Technologies and Systems (CTS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127931275","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}

Subjects detected changes more quickly in animate (anthropomorphic / zoomorphic) robots than their inanimate counterparts. This indicates that the domain-specificity of visual cognition allocates a different level of visual attention depending on robots' external appearances, and biotic features of robots' external appearances attract visual attention more than abiotic forms. Although the range of selected cases is not enough to represent all robot forms and the the particular aspects of biotic appearance that affect visual cognition were not defined, this research can lead further consideration of the visual cognitive system for the appropriate and rational design of robot forms.","PeriodicalId":426543,"journal":{"name":"2011 International Conference on Collaboration Technologies and Systems (CTS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129780879","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}

Leveraging reach and influence of such networks requires deeper understanding of how persuasive bias can be infused at individual and group level through exogenous control of the belief learning process in a network. Embedding linear control lends itself to a direct way to relate persuasive bias to the notion of communication exposure. We show in this paper that by applying linear exogenous control over DeGroot update cycles of beliefs, the agents can be persuaded to shift their beliefs in desired ways. We present the theoretical framework for such control and illustrate the theory with examples to show how consensus can be amplified or even destroyed.","PeriodicalId":426543,"journal":{"name":"2011 International Conference on Collaboration Technologies and Systems (CTS)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123645630","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}
