Support for work practice is better conceptualised as support for activity taking place in a multidimensional space than as prescription of temporal task sequences. The notion of "common artefact" is introduced to illustrate, unify, and summarise recent research that identifies significant dimensions of cooperative work. Common artefacts may be mundane, everyday objects like hotel keyracks or s...

This paper presents an innovative approach to solve the problem of missing transparency over competencies within virtual organizations. We based our work on empirical studies on the problem to cope with the problem of competence finding in such distributed organizations. Former studies have shown that central storage of profiles is inappropriate due to missing flexibility and high costs of main...

We consider compact invariant sets Λ for C maps in arbitrary dimension. We prove that if Λ contains no critical points then there exists an invariant probability measure with a Lyapunov exponent λ which is the minimum of all Lyapunov exponents for all invariant measures supported on Λ. We apply this result to prove that Λ is uniformly expanding if every invariant probability measure supported o...

This document describes an additional content type for the Cryptographic Message Syntax (CMS) [CMS]. The authenticatedenveloped-data content type is intended for use with authenticated encryption modes, where an arbitrary content is both authenticated and encrypted. Also, some associated data in the form of authenticated attributes can also be authenticated. All of the various key management te...

In this paper, we describe an O(|V (G)|) algorithm for finding a “non-separating planar chain” in a 4-connected graph G, which will be used to decompose an arbitrary 4-connected graph into “planar chains”. This work was motivated by the study of a multi-tree approach to reliability in distributed networks, as well as the study of non-separating induced paths in highly connected graphs. Supporte...

The flow equations or exact RG equations for the Higgs Top System are solved to leading order in 1/Nc. This allows to relate arbitrary bare actions with this field content continuously to effective low energy theories, and we find the flow converging towards general renormalizable models. The assumption of a bare action of the generalized Nambu-Jona-Lasinio type does not restrict the parameters...
