Very narrow spontaneous emission (Deltalambda similar to 0.5 nm), corresponding to a quality factor Q in excess of 800, has been obtained under continuous-wave excitation at room temperature with an AlInN/GaN monolithic microcavity. The structure is made o ...
The Direct Metal Laser Sintering process (DMLS) is a Rapid Manufacturing (RM) technique. A 3D object is built layer by layer through laser consolidation of metallic powders. Several industrial DMLS stations are commercialised. The current performances of t ...
In this paper we present our rational for proposing a conceptual model for the description of quality attributes of software artifacts, in particular suited to software components. The scientific foundations for our quality description model are derived fr ...
This paper addresses the problem of assessing distortions produced by watermarking 3D meshes. In particular, a new methodology for subjective evaluation of the quality of 3D objects is proposed and implemented. Two objective metrics derived from measures o ...
Severely disabled people are largely excluded from the benefits information and communication technologies have brought to our industries, economies, appliances, and general quality of life. But what if that technology would allow them to communicate their ...
This paper presents a framework for joint adaptation of an audiovisual content and its metadata. The presentation of the audiovisual content and its metadata are balanced to fit the given screen size in a way that maximizes user experience in browsing the ...
En se fondant sur une démarche de sociologie politique, l'objet de la thèse est d'étudier comment les nouvelles stratégies et pratiques des acteurs du système de régulation tendent à modifier le statut de l'usager. Pour cela, une grille d'analyse a été éla ...
