applications is limited to quite simple operations such as searching and downloading music files or movies. Hence, to benefit economically from the characteristics of Peer-to-Peer technology, there is need of additional, innovative applications for business us-age. A predestined scope of application

Collaboration on annotation projects is in practice mostly done by people sharing the same room. However, several models for online cooperative annotation over the internet are possible. This paper explores and evaluates these, and reports on the use of peer-to-peer technology to extend a

Abstract — Popularized by Napster and Gnutella file sharing solutions, peer-to-peer (P2P) computing has suddenly emerged at the forefront of Internet computing. The basic notion of cooperative computing and resource sharing has been around for quite some time, although these new applications have

Despite the fact that telephony is a form of peer-to-peer com-munication, the control-plane of telephony applications has traditionally followed hybrid- peer-to-peer model. In this model, centralized servers are required for call-control and other necessary procedures for managing the telephony ses

systems, such as NFS and HDFS, have been designed and deployed. Such systems provide access to files stored on multiple hosts connected through a computer network in a transparent way to users. The peer-to-peer network paradigm has been introduced to overcome some limitations of the client

Abstract We adapt the principle of auxiliary space preconditioning as presented in [J. Xu, The auxiliary space method and optimal multigrid preconditioning techniques for unstructured grids, Computing, 56 (1996), pp. 215–235.] to H(curl; ω)elliptic variational problems discretized by means of edge elements. The focus is on theoretical analysis within the abstract framework of subspace correction. Employing a Helmholtz-type splitting of edge element vector fields we can establish asymptotic h-uniform optimality of the preconditioner defined by our auxiliary space method.

Abstract: The purpose of this study was to determine if peer-to-peer technology training would be a viable option to traditional staff development. On-site, peer “experts ” conducted the training over a period of four and one-half weeks. Two mentors and three protégés completed the training

Mobile devices have in the recent years been able to form peer-to-peer networks making it possible for people to share information and interact. This technology makes it possible to create new tools that initiate and improve human collaboration. The paper presents experiences from creating a

Metadata for the World Wide Web is important, but metadata for Peer-to-Peer (P2P) networks is absolutely crucial. In this paper we discuss the open source project Edutella and related projects, which combine semantic web and peer-topeer technologies in order to make distributed learning

ontologies need a long development phase and are difficult to maintain. [BBT02] suggest a distributed approach to Knowledge Management which better fits the true situation in organizations and the processes people are used to. From a technological point of view peer-to-peer (P2P) solutions are particularly
