Although there are several approaches to implement cross-functional and heterogeneous infrastructures, these solutions do not consider high-tech laboratories. Therefore, we developed a service-oriented architecture for laboratories called LTM-SOLA, an application to control the devices by a modern web interface based on JavaEE and Seam technologies. Furthermore, we show how to use field bus couplers instead of programmable logic controllers (PLC) to enable single laboratory devices to be used in different test environments.","PeriodicalId":232795,"journal":{"name":"2009 5th International Conference on Collaborative Computing: Networking, Applications and Worksharing","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122477180","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}

Virtual knowledge spaces are a concept to build up flexible and adjustable environments for cooperative work and learning processes. When developing authorization concepts for virtual knowledge spaces, different boundary conditions have to be considered. Basically, we identify the specific requirements for the creation of coherent and intuitive rules to reduce the administrative complexity to a minimum and prevent mistakes. Furthermore we turn attention to flexibility of the authorization infrastructure as well as performance issues. The rights management described in this paper ought to fulfill these requirements.","PeriodicalId":232795,"journal":{"name":"2009 5th International Conference on Collaborative Computing: Networking, Applications and Worksharing","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126610262","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 facilitation of awareness and discovery of users in the communications networks is a key requirement for the success of these collaborative systems. Besides the need for location awareness, the emergence of heterogeneous wireless environments, where users can freely roam, is making Location Management (LM) an increasingly important topic for network operators. In this paper, we use a general model for LM signaling costs to obtain analytical expressions for their optimization. These expressions are applicable to different LM algorithms and scenarios, contributing towards the development of a standardized performance evaluation technique and to deliver guidelines for the optimum design of Location Areas (LAs). We also illustrate how modifications in the different parameters involved in the LM costs affect the optimum number of cells per LA and the value of the optimum LM costs.","PeriodicalId":232795,"journal":{"name":"2009 5th International Conference on Collaborative Computing: Networking, Applications and Worksharing","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129395720","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}

They can control when they communicate with each other, view each others' actions, and input concurrently. To understand how this control is exerted in practice, we have performed experiments at two different organizations, Microsoft Research and Tata Consultancy Services, which involved about forty six person hours of distributed side-by-side development. The experimental tasks were typical of the kind carried out at these organizations. A mix of qualitative, quantitative, and visualization analysis shows that (a) distribution and conflicting changes are not an issue; (b) developers use the unique capabilities provided by distributed side-by-side software development; and (c) the exact usage depends on several factors such as the collaboration task, developers, and software-development abstraction and environment.","PeriodicalId":232795,"journal":{"name":"2009 5th International Conference on Collaborative Computing: Networking, Applications and Worksharing","volume":"555 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123314763","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 features give end users the ability of being aware of the “quality” of the resources they are accessing, based on the opinions of the members of their community, and of being informed whether such resources can be safely used, according to the requirements specified by end users themselves. Besides illustrating the main characteristics of the QSN and its architecture, we describe its prototype implementation, carried out in the framework of the QUATRO Plus EU project, and its application to a use case scenario, involving groups of teenagers from three different European countries, acting as Youth Panels of the Safer Internet EU Programme.","PeriodicalId":232795,"journal":{"name":"2009 5th International Conference on Collaborative Computing: Networking, Applications and Worksharing","volume":"41 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123477105","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}

We first present our observation that a mediated service interaction is synchronizable. This fact is a prerequisite of our approach. Hereafter, we formally model a protocol scenario (i.e., a part of a service protocol to be enacted in an expected interaction) and an adapter, generate an adaptation logic, and formalize a mediated service interaction and its conversation. These formalization enables one to perform a formal verification that checks whether or not, as well as under which condition, an expected interaction is achievable. The technique presented in this paper complements the efforts of adapter synthesization for ensuring the achievability of a certain expected interaction.","PeriodicalId":232795,"journal":{"name":"2009 5th International Conference on Collaborative Computing: Networking, Applications and Worksharing","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124056264","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}

One of the fundamental problems associated with the issue is the lack of support of a user-centric approach to managing and sharing user profile information in current SN systems. In this paper we present a user-centric approach based on a credential system to enabling a user-controlled attribute (persona) sharing in online SN sites. Specifically we extend a Google-initiated open source project called OpenSocial, which provides a framework to support user attribute sharing between gadgets and online SN sites, in order to allow users to selectively share their attributes among online SN sites.
