Modeling anaerobic bioreactor landfills in methanogenic phase Introduction Biodegradation of municipal solid waste (MSW) in landfills is a complex and variable process Landfills develop distinctive microbial ecosystems during different decomposition phases. Waste decomposition phases ranging in number from three to...
Aircraft Performance modeling The main goal of an aircraft performance model is to predict with a certain level of accuracy the actual aircraft and engine performance. The word “performance” in this context refers mainly to flight parameters describing the aircraft...
Thyristor-based rectifier bridges The principal references used for the basic understanding of the thyristor rectifier bridges comes from Mohan (2003), Kundur (1994) and Erickson R. (2004), as they all touch the subject, but Erickson R. (2004) goes more into detail....
Aeronautics contribute to climate change and degradation of air quality around airports through its emissions of greenhouse gases (CO2, water vapor), pollutant gaseous and its particulate emissions (soot, organic aerosols ...). In addition, fuels from this transportation sector are mainly...
Approaches for modeling safety critical systems Many model-based approaches have been proposed recently to support the development of software in the context of safety-critical systems. Although our research problem is particularly aimed at airborne software and their development according to...
MODELISATION DU PROCEDE DE SOUDAGE PAR POINT General Methodology for Weld Simulation A generalized principle and methodology of weld simulation is proposed by Ferrase et al.,[FER98-1], to study the thermal characteristics in mash seam process modeling. Different stages to establish...
ETUDE DE LA PHOTOPILE AU SILICIUM SOUS ENVIRONNEMENT MATLAB/SIMULINK POUR DIFFERENTS REGIMES Les caractéristiques de la photopile en régime statique Techniques de détermination des paramètres de recombinaison et le domaine de leur validité d’une photopile bifaciale au silicium polycristallin sous...
INFLUENCE DE LA TEMPERATURE SUR LES PARAMETRES ELECTRIQUES Capacitance voltage characterisation of poly si-sio2-si structures Dans cet article, les auteurs ont étudiés la caractéristique C-V en haute fréquence des condensateurs poly Si-SiO2-Si. Une extension des caractéristiques C-V haute fréquence connus...
Définition du domaine des « mathématiques discrètes » Les mathématiques discrètes constituent une branche des mathématiques relativement jeune, sans définition conventionnelle partagée par les mathématiciens (Maurer, 1997). Plusieurs tentatives de définition du champ ont été proposées. Nous pouvons distinguer les...
In this thesis we are essentially interested in the mathematical modeling of wave propagation phenomena by using Green’s functions and integral equation techniques. As some poet from the ancient Roman Empire inspired by the Muses might have said (Hein 2006):...
