These are processes where intense interaction takes place between team members with a common goal. The paper identifies technology as an enabler of the collaborative work practices in such processes. To do this technology must provide intuitive interfaces to support such work practices while at the same making it possible to change such interfaces as work practices change. The paper proposes a collaborative metamodel as the basis for defining collaborative work practices and their changing nature. It proposes that the metamodel concepts be provided at the interface to provide commands to adapt interfaces to changing work practices and illustrates this with an implementation. It then suggests that agent support can be a useful enabler to support change","PeriodicalId":283620,"journal":{"name":"Proceedings of the 2005 International Symposium on Collaborative Technologies and Systems, 2005.","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123705730","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 mechanism involves the collaboration of the software agents to collect, organize and efficiently exchange resources information. The main goal is to provide an accurate single system image for all the resources. The concept of virtual clusters is used to enhance localization of information and minimize exchanged messages. This mechanism is introduced as a part of the run-time support layer in Delmon. Delmon is a three-layer middleware framework for distributed systems, which includes the run-time support layer. This layer utilizes agents that reside on the participating machines and communicate with one another to perform the required functions. The agents hide the details of scheduling, controlling, monitoring, and executing user jobs, while the management of system resources is made transparent to the user. The proposed mechanism for collaborative resource discovery is based on the hierarchical structure of the agents and the organization and update protocols","PeriodicalId":283620,"journal":{"name":"Proceedings of the 2005 International Symposium on Collaborative Technologies and Systems, 2005.","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129502635","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 is widely recognized that delay and jitter cause significant problems for CVEs. Most solutions to this problem revolve around techniques to compensate for this lag at the networking level. More recently, the usage of visual cues indicating network lag to the user have shown to be effective. In this article we examine both approaches using a collaborative tele-haptic application, during which we also introduce a novel technique for decorator-based mitigation for closely-coupled tasks.

Rather than defining the dependencies between activities, our focus is on the structure of coordination within the organization. The approach is guided by a need for scoped information and communication spaces, decentralized ownership of work product and process, and support for varying levels of work definition, integrating structured models of work process with ad-hoc activities. The base of the approach is a peer-to-peer style with peers supporting work participants. Peers are subdivided into active task spaces, associating information resources, software components, and communication. Independent connectors define the relationships between peers and provide the mechanism for defining larger more complex structures.
