 In this paper, we construct the solution expressions of fourth order nonlinear difference systems

Φn+1       =                   Φn−2Ψn−3                       ,
        α + Ψn (±1 ± Γn−1Φn−2Ψn−3)
Ψn+1       =                  …

In this paper, we investigate the form of the solutions of two systems of rational difference equations of second order, where the initial conditions are arbitrary nonzero real numbers.

Un des problèmes essentiels de l’utilisation de l’énergie solaire est les faibles échanges thermiques entre le fluide caloporteur et l’absorbeur du capteur solaire. Par contre, l’introduction de chicanes (obstacles) disposées en rangées dans les…

We propose in this paper, a numerical study of a planar impacting jet flow. The flow is assumed isothermal, laminar and unconfined. The developed computer code is based on the finite volume method, which was used to discretize the N-S equations. The…

This research lies within the scope of environmental research for seeking solutions for the optimizations of energy in the electrical supply network ADE- Adrar (Algérienne des Eaux d’Adrar/Algeria). Indeed, the principal aiming of this research is…

During the last two centuries we have known nothing but exponential growth and in parallel we haveevolved what amounts to an exponential-growth culture, a culture so heavily dependent upon the continuance of exponential growth for its stability that…

The objective of the developed system is to encourage efficient water management practices that optimize the usage of water by keeping crop health and yield intact through the implementation of an automated irrigation system. The study aimed to…

L’économie mondiale actuelle doit faire face aux problèmes de pénurie et de pollution des énergies fossiles. Dans ce contexte, la conversion de la biomasse en biocarburants semble être une solution de choix pour pallier à ces problèmes. Le bioéthanol…

This paper presents simulation of a photovoltaic panel connected to a load through a boost converter. Due to the nonlinear characteristics of the PV panel and in order to increase its performance, reduce cost of the application and improve the…

This study deals with the evaluation of the technical and environmental operation of solar/gas driven NH3/LiNO3 absorption chillers for malls under the environmental conditions of the city of Barranquilla, Colombia. It involves a sensitivity study on…
