We develop a joint playout buffer and Forward Error Correction (FEC) adjustment scheme for Internet Telephony, which incorporates the impact of end-to-end delay on the perceived audio quality. We show that it provides better quality than the adjustment sch ...
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 ...
We propose a method for fine grain QoS control of real-time applications. The method allows adapting the overall system behavior by adequately setting the quality level parameters of its actions. The objective of the control policy is to meet QoS requireme ...
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 ...

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 ...
The case presented in the paper shows how effective measurements can be made to help in the assessment of an important structure in a relatively short time frame using a combination of electronic inclinometers, temperature sensors and hydrostatic leveling. ...
We want to integrate colourfulness in an image quality evaluation framework. This quality framework is meant to evaluate the perceptual impact of a compression algorithm or an error prone communication channel on the quality of an image. The image might go ...
