On étudie numériquement la convection à double diffusion dans une enceinte horizontale. La cavité soumise à un gradient de concentration verticale est chauffée différentiellement au niveau de ses parois horizontales ou verticales. L'objectif du…

In this work, we show that the system of difference equationsxn+1=(ayn-2xn-1yn+bxn-1yn-2+cyn-2+d)/(yn-2xn-1yn),yn+1=(axn-2yn-1xn+byn-1xn-2+cxn-2+d)/(xn-2yn-1xn),where n belongs to the set of positive integer numbers, x-2, x-1, x0, y-2, y-1 and y0 are…

Dans cette étude, les caractéristiques du vent sont analysées en utilisant les données de la vitesse du vent recueillies pour cinq stations météorologiques au Liban et disponibles pour au moins une année (2 ans pour Klaiaat, 10 ans pour les Cèdres, 7…

Lebanon is facing currently anacute energy crisis, due tolack of domestic energy resources, reduced production capacities and a growing demand for energy. Relying on wind energy could reduce the impact of this crisis. However, continuous change in…
