In grid-connected photovoltaic systems significant improvements can be carried out in the design and implementation of inverters: reduction of harmonic distortion, elimination of the DC component injected into the grid and the proposed control. This…

Response surface methodology was used to determine the optimum processing conditions that yield maximum water loss and weight reduction and minimum solid gain during osmotic dehydration orange pieces (valencia late) in sugar solution using response…

Response Surface Methodology (RSM) was used to investigate the effect of temperature solution, immersion time, salt concentration and sucrose concentration on the water loss and solid gain during osmotic dehydration of tomatoes slices. The optimum…

This work aimed to conduct optimization method of ethanol production from using beet. To attain this objective, we propose to produce the distillation energy through biogas, and fertilizer for the culture of beet. We carried out some tests by using…

Biodiesel from renewable resources generally produced with the transesterification of vegetal oils or animal fats. In this study, we have improved the reaction conditions of the transesterification of the sunflower oil outcome in from frying. Fatty…

In this work, an impact of particulate matter (PM) on air pollution and its emissions released is investigated. Concentration levels of PM10 and PM2.5 in the Republic of Slovenia (RS) were analyzed on daily, weekly, monthly, quartile, and annual data…

Grid-connected photovoltaic systems are required to introduce photovoltaic solar energy into urban areas. To analyze these systems, a 15 MWp power system has been installed at the site of Oued Keberit a town and commune in Souk Ahras, province in…

Knowing that a large number of MPPT (maximum power point tracking) techniques exist so far and that each technique has its own advantages and disadvantages. Therefore, an appropriate examination of these techniques is indispensable to facilitate the…

Le développement de la technologie éolienne à vitesse variable et à fréquence constante est devenu un domaine d'intérêt majeur aujourd'hui pour la production de l’énergie électrique. Ce travail est une contribution à l'étude de la génération de ce…

Un grand nombre des maisons qui bordent le bassin méditerranéen sont organisées autour d’un patio. Cela est vrai pour l’Andalousie, la Grèce, le sud de l’Italie, les pays de la méditerranée, et particulièrement pour l’Afrique du Nord. Les origines de…
