Actually, current development of MAS nearly synchronously accompanies with the development of communication networks ever increasingly because the approaches of information exchange are mainly depended on the modes of data transmission and the spectacular of advanced communication technologies. The real detailed complexity inside the media transmission platform is masked in the proposed architecture of MAS so that the complex processes of data dissemination can be coped with reasonably and simply by way of decentralized intelligent agents. According to the simulation result and the comparison with other typical models of MAS, the presented architecture of MAS and its running mechanism exhibit better advantages such as flexibility, robustness and expansibility suited to the collaboration and interaction among decentralized agents in MAS. Toward the future research, some related optimal algorithms and running mechanisms concerning the integrated performance and the complexity of the MAS's architecture will be investigated and developed.","PeriodicalId":130458,"journal":{"name":"Proceedings. 2003 International Conference on Cyberworlds","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116765256","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 this paper, we focus on functional extensibility in CVE, and give the solution by using the conceptual idea of our proposed CIM approach, called task-oriented interaction management. This approach has four important components, which are scene interaction manager, virtual entity interaction manager, interaction task agent, and scene role & rules. They have certain capabilities, like data distribution, load-balance, tasks migration, ownership transfer, entities' states consistency maintenance, database persistency management and etc. The motivation of this research is to develop an extensible and evolving CVE with extensible functionalities for creating large-scale collaborative interaction experience to users in a large-scale interconnected 3D virtual environment.

The principal developed idea is that these environments are heterogeneous and open multi-agent systems. The MASCARET model is proposed to organize the interactions between agents and to provide them reactive, cognitive and social abilities to simulate the physical and social environment. The physical environment represents, in a realistic way, the phenomena that learners and teachers have to take into account. The social environment is simulated by agents executing collaborative and adaptive tasks. These agents realize, in team, procedures that they have to adapt to the environment. The users participate to the training environment through their avatar. In this article, we explain how we integrated in MASCARET models necessary to the creation of Intelligent Tutoring System. We notably incorporate pedagogical strategies and pedagogical actions. We present pedagogical agents. To validate our model, the SECUREVI application for fire-fighters training is developed.","PeriodicalId":130458,"journal":{"name":"Proceedings. 2003 International Conference on Cyberworlds","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130065456","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 contrast, the field of virtual environments (VE) is fragmented with a wide proliferation of different systems, as a result of the current development trend. However, these divergent systems present a significant overlap of functionality that represents a waste of development resources and a detriment to innovation. This paper proposes Mayhem as a new approach to the design and development of VE systems. Our approach relies heavily on component design methodology coupled with a simple layered approach to system architectures. The combination of the two promotes the construction of systems from smaller building blocks, which may have been developed by different sources, each specializing in the supported functionality. Although Mayhem promotes the trend of middleware, it requires a common base infrastructure - the Java Adaptive Dynamic Environment (JADE). To demonstrate how to build a VE system using Mayhem, the paper describes a simple prototype of a VE and some of its key building blocks.","PeriodicalId":130458,"journal":{"name":"Proceedings. 2003 International Conference on Cyberworlds","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126611970","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 a modern logic design classroom, hardware description languages such as VerilogHDL are mostly used to describe circuits for FPGAs. The circuit in each module is described in VerilogHDL and the entire circuit is implemented by combination of designed modules. These HDL descriptions are wrapped in XML and enriched by a specially extended XML vocabulary, in order to share designed modules among learners on the Web. Although XML gives us a common and convenient Web framework, it becomes difficult to verify, validate, and maintain conformance among designed modules if the system becomes very large. To overcome this problem, we employed the cellular models that ensure the consistency among design modules and support a top-down design methodology. The proposed top-down eLearning tools can generate these circuit design data, distribute them to the learner, and manage the design database. The circuit design data wrapped in XML vocabulary are offered to the learner as a self-learning material of the courseware using the top-down (i.e. goal-oriented) method, according to the demand.","PeriodicalId":130458,"journal":{"name":"Proceedings. 2003 International Conference on Cyberworlds","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116093638","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 major overhead of the model is the transmission of the depth images of the initial reference and the subsequent new views that may be up to a few Mbs in size depending on the screen resolution. This paper presents efficient compression techniques specifically designed for the depth images. Additionally we experiment with the warped image quality by reducing the resolution of the depth map. We show that significant compression can be achieved at a cost of a very modest impairment in the perceptual quality of the warped image.","PeriodicalId":130458,"journal":{"name":"Proceedings. 2003 International Conference on Cyberworlds","volume":"73 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133558727","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}
