Abstract— This paper proposes a simple yet efficient localization algorithm for GPS-free sensor nodes in wireless sensor networks (WSN). Our approach is hybrid in the sense that...
In this paper we present a prototyped system to enable the virtual exploration of a complex virtual environment. Our approach exploits Quest3D as main rendering engine, its output...

Role-based collaboration (RBC) is proposed to support people’s collaboration with more usable human-computer interfaces. To approach the objectives of RBC, new practical tools a...
In this paper, stereo matching and 3D visualization issues are studied for a linear pushbroom stereo model built for 3D gamma-ray (or x-ray) cargo inspection. A fast and automated...
In this paper we present the DANTE system, a tagger for temporal expressions in English documents. DANTE performs both recognition and normalization of these expressions in accord...
