Bio synthetic natural gas (Bio-SNG) is being proposed as an alternative to the natural gas of fossil origin (NG) [1]. Bio-SNG consists mainly of CH4 (at least 95%mol), has a high heating value (e.g. 10 kWh/m3N), and respects the quality standards of the NG ...
The identification of kinetic models is an essential step for the monitoring, control and optimization of industrial processes. This is particularly true for the chemical and pharmaceutical industries, where the current trend of strong competition calls fo ...
As new technologies enable a radical transformation of the learning process, new learning approaches and techniques appear, and the need for quality assurance of all learning assets emerges. Although, the existing e-learning standards have managed to cover ...
This paper presents a new approach for the design of a full reference objective quality metric for the assessment of color pictures. Our goal is to build a multi-channel metric based on the perceptual weighting of single-channel metrics. A psycho-visual ex ...
Audio coding based on Frequency Domain Linear Prediction (FDLP) uses auto-regressive model to approximate Hilbert envelopes in frequency sub-bands for relatively long temporal segments. Although the basic technique achieves good quality of the reconstructe ...

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 ...

Quality assessment is a central issue in the design, implementation, and performance testing of all systems. Digital signal processing systems generally deal with visual information that are meant for human consumption. An image, a video, or a 3D model may ...
Managers of photographic collections in libraries and archives are exploring digital image database systems, but they usually have few sources of technical guidance and analysis available. Correctly digitizing photographs puts high demands on the imaging s ...
Most quality management systems (QMS) which integrate software development are based on a single software development method. This particular method is enforced on all projects. The resulting QMS has to fulfil the ISO 9000 standards [13] and enables the co ...
