Today, renewable energies have become one of the most important concerns of the countries of the world as a result of the negative effects we have reached on the environment from our use of fossil fuels and the resulting emissions of toxic gases. It…

Dans le présent article, un nouveau concept de la commande PWM destiné au système de pompage photovoltaïque, est proposé. L'objectif est l’amélioration de la réponse spectrale et d’avoir une forme du courant du moteur sinusoïdale, par l'application…

يسعى هذا الموضوع إلى الكشف عن الإستراتيجية التي تبناها المشرع لمواجهةظاهرة الفساد في الجزائر ومدى توافق هذه الأخيرة مع شروط وبنود اتفاقية الأمم المتحدة لمكافحة الفساد ألا وهو نظام تسليم المجرمين.
حيث يتناول هذا البحث ويهتم بتشخيص ظاهرة الفساد في…

The fractional-order derivative of a non-constant periodic function is not periodic with the same period. Consequently, any time-invariant fractional-order systems do not have a non-constant periodic solution. This property limits the applicability…

In this paper, we study the existence of a continuous solution for a nonlinear integral equation of a product type. The analysis uses the techniques of measures of noncompactness and Darbo's fixed point theorem. Our results are obtained under rather…

L'étude numérique bidimensionnelle de la dispersion d'un polluant autour d'un obstacle soumis à un écoulement turbulent a été effectuée par la technique de Simulation des Grosses Structures L.E.S. Dans la première partie de ce travail, nous avons…

The objective of this work is to carry out a sizing program of the photovoltaic system isolated from the grid by determining the size of the subsystems that make up the photovoltaic generator, the batteries, the charge regulator and the…

Ce travail porte sur l’étude expérimentale de la digestion anaérobie des déchets ménagers organiques de la wilaya de Blida en condition mésophile (température allant de 35 °C jusqu’à 37 °C). Pour augmenter le rendement de production en biométhane,…
