L'objectif principal de ce PFE est l’optimisation de la machine "Dissoluteur Tank 300 Propack". Le rôle de cette machine est de préparer du vrac (chauffage ou refroidissement) pour une utilisation dans la deuxième zone de préparation du... more
a. La diode est passante. La loi de maille : b. La diode est bloquée ≡ I = 0A Exercice 2 1. E = +5V a. la diode n'est pas passante (polarisation inverse) : ≡ U R2 = E x R 2 / (R 1 + R 2) = 5V x 1 / (1+1) U R2 = 2,5V
ce document présente les dispositifs de protection des réseaux électrique surveillent en permanence l’état électrique des éléments d’un réseau et provoquent leur mise hors tension
This paper aims to present an implementation of the DEA cross-efficiency models in the environment R. R is a free software and open source, highly extensible that offers a variety of functions and graphical routines for data analysis. We... more

RESUMO A perspectiva de uma maior participação das fontes eólicas no Sistema Interligado Nacional aponta para a necessidade de incluir a previsão de curto prazo da geração eólica nos procedimentos da operação em tempo real e da... more
The typical load profiles are used in formulating the electricity distribution tariffs. Usually, clustering algorithms are used in identification of typical load profiles from a sample with load curves measurements. These methods... more
The performance evaluation of a power system can be carried out through deterministic and probabilistic approaches. Deterministic methods presents the basic limitation of not considering the essentially stochastic nature of power systems... more
The long-term electric power demand forecasting is based on a set of basic premises that includes the macroeconomic scenarios, the growth of the population and of the number of households. The latter is the main determinant to... more
Neste trabalho é descrita uma metodologia para previsão do consumo de energia elétrica da classe residencial, na qual são consideradas diversas estatísticas produzidas pelo IBGE, em especial, nas PNADs, nos Censos demográficos e nas... more
This work presents an R package to calculate the potential distribution on the surface above square or rectangular grounding grids, composed of parallel and orthogonal conductors buried horizontally in homogeneous soils. Despite assuming... more
