Boundary and virtual organisation theory were used to study the implications of organisation level virtualisation for work units. A single case study in a geographically dispersed public sector organisation revealed multiple implications of the coexistence of traditional and virtual work units. Different quality ICT access for traditional and virtual work units was found to result in conflictin...

This paper describes the work achieved by the MRIM research group of Grenoble, using some data from the LaHC of SaintÉtienne, in a way to test personalized retrieval of books for the Social Book Search Lab of CLEF 2015. Our proposal rely on a biased fusion of content-only retrieval, using BM25F and LGD retrieval models, user non-social profile based on the catalog of the requester, and social p...

An analysis of acoustic and gestural data generated from virtuosic cello performances was conducted using advanced pitch-tracking techniques and state-of-the-art gesture tracking devices. During the academic year 1990-91 the cellist Yo-Yo Ma collaborated with the Hyperinstrument research group at the MIT Media Laboratory; one of the goals of the research group was to develop a sophisticated ges...

The vision of using electron tomography (ET) for studying the 3D organization of biological materials – from molecules to cells – emerged in the late 1960s. However it was only in the 1990s that this vision began to materialize. Cryogenic sample preparation techniques replaced the artifact-prone techniques of the past, and automated acquisition schemes made possible the recording of tomographic...

Understanding of how and where NOx formation occurs in industrial boiler is very important for efficient and clean operation of utility boilers. This study aims to numerically simulate the NOx formation using a 3D model furnace of an industrial boiler. The studied boiler is a 160 MW and is gas fired with natural gas. The boiler combustion model is a 3D problem that involves turbulence, combusti...

Active contours and minimal paths have been extensively studied theoretical tools for image segmentation. The recent geodesically linked active contour model, which basically consists in a set of vertices connected by paths of minimal cost, blend the benefits of both concepts. This makes up a closed piecewise-defined curve, over which an edge or region energy functional can be formulated. As an...
