La présente étude a pour but la valorisation de cette biomasse en produisant du bioéthanol de deuxième génération, il s’agit d’une valorisation optimale qui passe par l'exploitation de la totalité des débouchés dans une approche intégrée de type "bioraffinerie" pour la production des sucres simples fermentescibles à haute valeur ajoutée. Dans une première étape, la biomasse a été dépolymérisée par un traitement à la vapeur. Ensuite, un traitement par l'acide sulfurique a été effectué pour la saccharification et la libération des sucres simples. Dans une deuxième étape et dans le but de réduire les composés phénoliques, le substrat issu a été décanté et filtré puis traité par le dihydroxyde de calcium. Parallèlement à l’hydrolyse chimique, la biomasse a été prétraitée par la steam explosion pour rendre tous ces composés accessible à l’hydrolyse enzymatique. En plus, les techniques et les variables d’hydrolyse chimique et biologique (la température, la pression, le temps, la concentration et les conditions de détoxification et de production d’enzyme) ont été optimisés. En conclusion, ce travail a permis de mettre au point un procédé biotechnologique pour valoriser la biomasse solide, qui permet non seulement de réduire l’impact environnemental, mais aussi de diminuer les coûts et d’ajouter une valeur socio-économique à ces déchets.

For medium and high temperature applications, a system for collecting solar energy at high temperatures was developed and built in this research work. The system, built at the center of development of renewable energy of the Algiers, consists of a 2=60°C included angle, R0=0.90 m diameter spherical reflector with a cylindrical receiver filled with water, tracking reflector which moves into the focus following the sun's movement. The system is capable of heating water or other fluids to temperatures above 350 °C, thus making it possible to obtain process heat for domestic use and to store solar energy in a compact and economical way. An analysis of the system's optical characteristics was performed to aid in the design of the spherical reflector and cylindrical receiver. The thermal performance of the system was analyzed. The effects of mirror reflection, concentration ratio, heat transfer to the fluid (water), incidence angle, size and form of the cylindrical receiver, environmental conditions (wind, ambient temperature), have been studied by means of thermal model. The performance of the spherical reflector was tested by the temperature of the water. Total efficiencies (solar to thermal) of = 60% - 70% were obtained for a wide range of temperatures up to 350 °C. The results of the present study show that it is possible to use the spherical reflector for systems requiring process heat and make possible substantial utilization of solar energy and considerable savings relative to fossil energy in the sunny countries of the world.

To carry out these studies, a look into the dynamic stability of the electrical network, and the stability within the meaning of Lyapunov was effected. Then a modelling of our network with application under MATLAB/Simulink was carried out as well as the tests of simulations without disturbances, and another test with disturbances was made. This reveals that the Douala network suffered falls in voltage, increasing instability depending on the critical disturbances, with the network eliminating the faults slowly.

Dans ce travail, la technique des ondelettes est utilisée pour détecter la rupture des barres rotoriques et les portions d’anneau de court-circuit. La détection est basée sur le fait que n’importe quelle rupture au niveau du rotor induit une déformation dans la FMM de l’entrefer qui se traduit par des composantes supplémentaires dans les courants statoriques. La technique est validée sur des signaux expérimentaux obtenus à partir des machines asynchrones à cage défectueuses.

L’optimisation de l’extraction des sucres des sous-produits de dattes a été effectuée en utilisant la méthodologie de surface de réponses, ‘MSR’, par le plan d’expérience de Doehlert. Le facteur ratio pulpe/eau (X3), qui a influencé significativement la concentration des jus en sucres, a été modélisé et optimisé. Il a été possible d’avoir des jus avec des concentrations élevées en sucres (220 g.l-1). Les essais de fermentation alcoolique menés dans un milieu de culture à base de jus de dattes à 17.4 °Brix, conduisent à la production d’éthanol aux concentrations de 63 g.l-1, 41 g.l-1 et 33 g.l-1, respectivement pour les levures Saccharomyces cerevisiae, Candida Pelliculosa et Zygosaccharomyces rouxii. Les essais menés dans le milieu à 35.8 °Brix (milieu de culture se rapprochant le plus des sirops de dattes brutes) montrent que la croissance des levures Saccharomyces cerevisiae et Candida Pelliculosa est inhibée par la pression osmotique élevée causée par la haute concentration en sucres. Seule la levure xérotolérante Zygosaccharomyces rouxii s’est adaptée au milieu en produisant 55 g.l-1 de bioéthanol.

Les blocs sont fixés sur la paroi inférieure adiabatique qui est soumise à un jet d’air vertical, celle du haut est maintenue froide à une température TF < TC. Les parois verticales sont rigides et adiabatiques. Les équations gouvernantes sont résolues à l’aide la méthode des volumes de contrôle. Notre intérêt est porté à l’effet de l’inclinaison sur la symétrie de la solution et le transfert de chaleur. Les principales paramètres de cette étude sont l’angle d’inclinaison 0<=<=90°, le nombre de Rayleigh Ra=105 , le nombre de Reynolds 100 <= Re <= 1000, le nombre de Prandtl Pr=0.72, la hauteur des blocs B=0.5, la largeur des ouvertures C=0.15 et la distance entre les blocs D=0.5. Les résultats sont présentés sous forme de lignes de courant et du champ de température.

Pour cela, nous proposons un schéma de commande de la machine synchrone, comportant un premier dispositif alternatif/continu suivi d’un second dispositif continu/alternatif. Le principe MPPT repose sur la variation de vitesse de la turbine suivant celle du vent en cas de raccordement indirect de la génératrice avec le réseau. Les simulations sur Matlab-Simulink, présentées en fin d’article, confirment une bonne adéquation du schéma de commande, du choix des paramètres de réglage ainsi que l’architecture de la chaîne de conversion aux objectifs assignés.

Ce travail a pour objectif de dresser un état du lieu sur la variabilité du couvert végétal à travers le territoire de l’Algérie. Pour réaliser ce travail, la donnée de base utilisée est l’indice de végétation normalisée NDVI. A partir de ces images, NDVI décadaire du satellite NOAA, l’analyse statistique nous montre globalement une alternance interannuelle des maximums mais la tendance reste stationnaire sur toute la période. Des anomalies négatives de l’ordre de 0.1 sont enregistrées sur l’ensemble des régions proches côtières, contrairement des anomalies significatives positivement sont enregistrées sur les Aurès. Les valeurs de l’écart type sont nettement faibles par rapport à la climatologie sur toutes les régions. Pour le mois de juillet de la même année, le couvert végétal a nettement reculer plus au nord et les fortes valeurs sont observées sur les montagnes du centre, de l’Est et de l’extrême est de l’Algérie. La comparaison des valeurs NDVI calculées à partir des images météosat (MSG) montre bien une sous-estimation par rapport à celles calculées à partir NOAA AVHRR. MSG reste encore non adapter pour le suivi de la végétation éparse ou de type saharienne non étoffés et bien localisées.
