In this work informal learning theories and practices and social networking features are taken as starting points to build a reference collaboration model to support collaborative ...
Abstract. We investigate two associative products over the ring of symmetric functions related to the intransitive and Cartesian products of permutation groups. As an application, ...
This paper shows how a corpus of instant messages can be employed to detect de facto communities of practice automatically. A novel algorithm based on the concept of Edge Stress F...
We describe a new model for studying intermittently connected mobile networks, based on Markovian random temporal graphs, that captures the influence of message size, maximum tol...
