To this end, a classification scheme is presented which groups the shared workspaces based on multiple orthogonal criteria. For visual displays, this includes the group-orientation of the applications, the organization of the display, and the contiguity relationships among display images. The same classification criteria are applied to the audio component, which considers the group-orientation of the audio channel, the organization of the speaker systems, and the contiguity relationships among the audible ranges of the speakers. The classification also covers the floor control concepts and design approaches. The classification is applied to a known groupware system, MERMAID, as a case study.<<ETX>>","PeriodicalId":251095,"journal":{"name":"1993 4th Workshop on Future Trends of Distributed Computing Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131247423","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}

It incorporates variants of several important techniques of artificial intelligence to provide recommendations for the allocation of a set of knowledge sources to a set of processors. To provide intelligent recommendations, an expert system acquires the same information about the two domains as an analytical allocation algorithm. However, while most allocation algorithms are limited to finding a minimum cost solution, the expert scheduler considers the complexities of constraints and multiple objectives of the practical system and/or application.<<ETX>>","PeriodicalId":251095,"journal":{"name":"1993 4th Workshop on Future Trends of Distributed Computing Systems","volume":"23 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134033289","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 design and implementation of a framework to support the construction of interactive and cooperative applications must consistently extend the models and architectures of single-user applications. The requirements for this extension include the management of the communication and coordination between users, the support for several levels of feedback (feedback about machine activities, individual user activities, and group activities), and the handling of the synchronization issues. The authors describe a distributed cooperation system based on a user interface toolkit and an interactive construction tool. The toolkit and tool were extended to enable communication data sharing, and coordination among several interacting users.<<ETX>>","PeriodicalId":251095,"journal":{"name":"1993 4th Workshop on Future Trends of Distributed Computing Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129653859","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 basic weaknesses of these models for use in practical system design and evaluation are pointed out. It is also pointed out that the state of the art in analytic modeling and evaluation of fault-tolerant distributed computer systems has a vast weakly characterized region in the domain of conceivable component models enclosed by the two extreme models. The main constructive proposition made with respect to advancing the state of the art is to establish scientific procedures for fair distribution of concerns over possible occurrences of anomalous events during system design and validation. A direction for obtaining such a procedure relying on extensive probabilistic reasoning is proposed.<<ETX>>","PeriodicalId":251095,"journal":{"name":"1993 4th Workshop on Future Trends of Distributed Computing Systems","volume":" 43","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113947069","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 authors introduce the set of generic events that are monitored by different development activities for distributed systems and identify other desirable monitoring properties for an efficient monitoring pool. They then give an overview of the newly introduced constructs, called tapping processes, that extend orthogonal languages so that this language-based approach can also be used as an event-based approach for the development of distributed systems. Those constructs provide accurate information about monitored systems without causing any perturbation. To illustrate the advantages of the new approach, it is shown in detail how the Hermes programming language was extended to include the tapping processes' constructs.<<ETX>>","PeriodicalId":251095,"journal":{"name":"1993 4th Workshop on Future Trends of Distributed Computing Systems","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128983407","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}
