Design of collaborative learning (CL) scenarios is a complex task, but necessary if the goal of the collaboration is learning. Creating well-thought-out CL scenarios requires exper...
— This paper evaluates the capability of Application Layer - Forward Error Correction (AL-FEC) with Raptor coding for improving the reception of DVB-H streaming services for mobi...
In this paper we define a notion of leak extraction from a block cipher. We demonstrate this new concept on an example of AES. A result is LEX: a simple AES-based stream cipher wh...
Streams are acyclic directed subgraphs of the logical ow graph of a proof representing bundles of paths with the same origin and the same end. The notion of stream is used to desc...
Representations and processes involved in judgments of spatial relations after route learning are investigated. The main objective is to decide which relations are explicitly repre...
