This is even more true in case of collaboration and interoperability between different organizations and thus between their information systems.Usual solutions do not anticipate interoperability security requirements or do it in a non satisfactory way. In this paper, we propose contract and compatibility principles to achieve a secure interoperation. Contracts are used to explicitly represent the rules that determine the way interaction between organizations must be controlled to satisfy secure accesses to resources. Compatibility relations make it possible to derive interoperability security policies.","PeriodicalId":202698,"journal":{"name":"2008 IEEE International Conference on Signal Image Technology and Internet Based Systems","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125936963","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 other words, we are interested in systems that can perform a task by subdividing it in easier tasks and by using the knowledge about each agent already introduced in the system. The idea is to prefabricate a basic structure that can be reused by either changing the main goal or by adding several different specialized agents. The main characteristic of our methodology is that each complex agent contains a schematic definition of other agents. Each agent is thus able to retain and produce certain information, such as the time needed to accomplish a certain task, taking into account a given set of agents and resources. This allows to quickly produce information regarding the necessities in resources and derive the demands to other subsystems.In order to increase the applicability of our approach, we have fully implemented a tool that allows us to graphically specify complex systems. In addition, the tool allows us to simulate the behavior of the specified systems so that some interesting properties, such as starvation and maximal progress, can be studied.","PeriodicalId":202698,"journal":{"name":"2008 IEEE International Conference on Signal Image Technology and Internet Based Systems","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115623331","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}

As there are many reasons behind this, main cause can be attributed to the lack of awareness of usability from developers' point of view and little interaction of project stakeholders with human-computer interaction (HCI) studies. In order to increase the usability hence the competitiveness of open source software applications, developers need to measure their usability activities within the project, and to conduct appropriate user centered design methodologies. In this paper, a measurement method that focuses on open source project is proposed based on the motivation to improve the usability of applications and increase the efficiency of communication and collaboration level of HCI experts and developers.","PeriodicalId":202698,"journal":{"name":"2008 IEEE International Conference on Signal Image Technology and Internet Based Systems","volume":"286 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116593918","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}

When blur is present, the type and degree of degradation vary from one image to another. The process of restoring these images are usually computationally demanding so that there is a need to first detect blurs. If an image is not blurred then it need not undergo the restoration process. In this work, a novel algorithm that simultaneously detects and identifies blurs, is proposed. This method is based on the analysis of extrema values in an image. The extrema histograms are first constructed then analyzed in order to extract feature values. The distinctness of these values in the presence of blur is used. It is computationally simple and fast thereby making it suitable for preprocessing especially in practical imaging applications. Experimental results on natural images and its synthetically blurred versions show the validity of the proposed method.","PeriodicalId":202698,"journal":{"name":"2008 IEEE International Conference on Signal Image Technology and Internet Based Systems","volume":"51 1-2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131451889","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}

Because the discussion in a community is concentrated, the viewpoint narrows. We believe that it is necessary to provide information about the lack of awareness of a user to the users of community-type content. Information about which a user is unaware is called as a \"content hole,\" and searching for such holes is called as \"content hole search.\" In this paper, as a first step toward developing a technique for searching for content holes, we attempt to extract and represent important but neglected content from online community-type content based on isolated and non-related degrees. This content is information that nobody from the community is interested in, but that may be of interest to many people outside the community.","PeriodicalId":202698,"journal":{"name":"2008 IEEE International Conference on Signal Image Technology and Internet Based Systems","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133269482","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 proposed method which is capable of accurately locating region boundaries has the following salient features. First, it is a non-supervised approach which reflects the non-local properties of the image. Second, it guarantees that the regions are connected. Finally, it produces robust results which is almost unaffected by the influences of outliers. In thistechnique, at each step, a minimum weight edge is selected and the two regions connected by the minimum weight edge are considered for merge. The merging of regions is carried out, if the mean of the edges connecting the two regions is smaller than the maximum of the mean of the intra region edges along with the threshold value.","PeriodicalId":202698,"journal":{"name":"2008 IEEE International Conference on Signal Image Technology and Internet Based Systems","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133445430","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}

This difficulty is due to the complexity level of such systems as well as their variety and increasing distribution. To guarantee such a respect, we need to test the target Web system by applying a complete set of test cases covering all the possible scenarios. To reach this aim, we first specify the Web system behavior from its functional point of view using IF language. Second, this model is augmented by applying a set of dedicated algorithms to integrate timed security properties specified in Nomad language. This language is well adapted to express security properties with time constraints. Then, we use a dedicated tool called TestGen-IF, to perform an automatic test generation of test cases targeting security purposes. These test sequences are transformed in executable test cases that can be applied on a real Web application. We present in this paper an industrial Web-based system provided by France Telecom as a case study to demonstrate the reliability of our framework.","PeriodicalId":202698,"journal":{"name":"2008 IEEE International Conference on Signal Image Technology and Internet Based Systems","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115487546","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}
