Numerical Optimization of a Tandem Solar Cell based on InxGa1-xN

This article examines the best fraction of indium (x) and critical depth (H) of a single junction tandem photovoltaic (PV) cell (InxGa1-xN) in the vein to optimize its electrical efficiency. For better investigation, the optical and electronics…

Etudes sur le diagramme de phase des matériaux composites à base d’un cristal liquide ferroélectrique stabilisé par un réseau de polymère et leurs propriétés thermo microscopiques et électro-optiques

Dans cette étude, nous avons montré que le critère de solubilité du monomère dans le cristal liquide est bien rempli. De plus, le caractère mésomorphe du monomère lui confère la capacité de s’orienter dans le milieu cristal liquide, ce qui est très…

Bibliometric Analysis and Challenges in Biofuel Production using Petroplants

A bibliometric analysis based on PubMed database were carried out to provide insights into research activities and tendencies, challenges of global biodiesel from 1997-2020.The document type and language,characteristics of publication output,…

Indigenous kaolinite ore as cost effective adsorbent for re-refining of used lubricating oil

Present study evaluates efficiency of indigenous kaolinite ore as environment friendly and low cost adsorbent for re-refining of used lubricating oil. Thermo gravimetric analysis was used to find the mass variation with rise in temperature. Different…

Contribution à l’étude de la durabilité de mortier de plâtre à base de sable de dunes renforcé par des fibres de palmier dattier

L'objectif principal de cette étude, c’est la valorisation des matériaux locaux (plâtre, sable de dunes et les fibres de palmier dattier) pour la région du sud algérien. Élargir le domaine de l'utilisation de ces matériaux dans la construction. Nous…

Direct power control based virtual flux using SOGI-FLL estimator for BDFIG-WEC system

This paper deals with the control aspect of the brushless doubly fed induction generator, 'BDFIG' incorporating in a wind energy conversion system, 'WECS'. The control process may divide in two main parts control of machine side converter, MSC' and…

Détermination de la vitesse de séchage du Curcuma par analogie au modèle de sorption de Bradley

In Madagascar, the drying of Curcuma consists of exposing them directly to the Sun. This is not always productive. This work aims to provide information on the drying of turmeric by determining the drying curve in order to consider industrial drying.…

Quintic and Septic $C^2$-spline methods for initial fractional differential equations: Quintic and septic $C^2$-spline methods

In this paper, we developed Quintic and Septic C2C2-spline methods for solving initial fractional differential equations. The convergence analysis of the methods is discussed. Illustrative examples are included to demonstrate the validity and…
