This paper presents a comparison study in different techniques of maximum power point tracking (MPPT), which have been experimented and validated by simulation in the proposed PV system. The main aim of each MPPT technique is to enhance and optimize…

In this work we present a numerical study on the aerodynamic behavior of a vertical axis wind turbine of the Savonius type for different axial positions between the blades (overlap rates a/D). The study focuses on predicting the effect of the axial…

This research paper aims to examine the problem of pricing ecological products under competition. The research concluded that the pricing problem lies mainly in the quality of the ecological product that is characterized by quality and positive…

The impact of geographical diversity on general and specialized language has contributed to increasing the complexity of the translator's work and highlighted the importance of linguistic studies aimed at studying geographical linguistic problems. In…

The energy balance components of a greenhouse as well as the greenhouse design may strongly impact the greenhouse energy. Few studies were devoted to the description of the energy balance components of a greenhouse located in the semi arid region of…

Dans ce travail, nous avons développé quelques modèles théoriques qui permettent d’estimer le rayonnement solaire global reçu au sol. Ces modèles tiennent compte des effets de diffusion et d’absorption que subit le rayonnement solaire lors de sa…

This work considers a large-scale multisite investigation of the effects of sunshine duration on Algerian territory. It also studies the correlation between sunshine duration and commonly used climatic parameters (temperature, water vapour pressure,…

A modeling method of switched reluctance generator (SRG) for wind energy applications based on the nonlinear inductance model and electromagnetic field finite element analysis (FEA) has been proposed in Matlab/Simulink environment, the power…
