Etude de la vitesse du vent avec la distribution de weibull : cas de la ville de cotonou au Benin
Journal de la Recherche Scientifique de l’Université de Lomé, 2015 Dans le but d’améliorer la production de l’énergie électrique et surtout d’explorer des sources complémentaires aux sources d’énergies existantes, nous avons choisi d’étudier la vitesse du vent au Bénin. Cette étude a été faite avec la distribution de probabilité de Weibull dans le but de calculer la puissance éolienne récupérable à Cotonou.

UN FRAILTY GAMMA EN SUPERVIVENCIA BIVARIANTE UN FRAILTY GAMMA EN SUPERVIVENCIA BIVARIANTE
Revista Colombiana de Estadística, 2004 We consider a bivariate survival model with the presence of an unobserved random covariate, frailty, that induces dependency between the failure times and acts according to a proportional hazard model.

Energy Science &Engineering, EarlyView.The proposed hybrid osprey‐salp swarm optimization algorithm addresses optimal power flow (OPF) problems in smart grids incorporating solar, hydro, and thermal generators. The algorithm is validated on Institute of Electrical and Electronics Engineers 30‐, 57‐, and 118‐bus test systems across five single and multiobjective OPF scenarios.

Fire and Materials, EarlyView.ABSTRACT This study addresses the influence of fibre architecture on the mechanical properties of vacuum‐infused glass fibre reinforced polymer (GFRP) composites at elevated temperatures (ET). Laminates with three different fibre configurations—unidirectional (UD), bidirectional 0°/90° cross‐ply (BD), and ±45° off‐axis angle‐ply (OA) – were tested in ...
