Nana Goumwêndkouni Gilbert , Konfé Amadou , Ouédraogo Souleymane , KyThierry Sikoudouin Maurice , Kam Sié and Bathiébo M. J. Dieudonné
The evaluation of the solar deposit is essential for the sizing of photovoltaic systems. This requires the availability of radiation data. In Burkina Faso, weather data doesn’t cover all the country. That makes that solar radiation measured are not available for the all country. Theorical methods can help about it. This paper is written to fil(...)

Energy Performances Analysis of a Solar Electric Car in Togo
Kokou Prosper Semekonawo, Sié Kam
In sub-Saharan Africa the cost of transport is very expensive for the populations. As the car fleet is mainly made up of thermal cars, the high cost of transport is largely linked to the oil’s import. Faced with such a situation, it is important to find other means of transport in order to reduce the transport’s cost for the populations. One o(...)

Experimental Study of Papaya Drying in an Indirect Solar Dryer in Natural Convection
Dianda Boureima, Traore Abdoul Fataho, Ouedraogo Adama, KY Sikoudouin Maurice Thierry, Ouedraogo Issaka, Kam Sié, athiébo Dieudonné
Papaya is a fruit that is prized for its flavor and also for its different appearances. It is seasonal and
easily perishable in our climatic conditions. This work is devoted to the improvement of
conservation techniques such as drying. We conducted our experimental work in an indirect solar
dryer in natural convection under(...)

Linear Regression and ARIMA Models for Electricity Demand Forecasting in West Africa
Kokou Prosper Semekonawo; Sié Kam
This article focuses on the predictive study of electricity demand in West African countries based on the multivariate linear regression model and the ARIMA model. The objective of the study is first to establish for each country a linear regression model and ARIMA model, then to compare the two (2) models based on the MAD, RMSE and MAPE coeff(...)

Abstract
Living in a habitat with comfort is requested by all. Cinder block bricks have poor thermal properties, leading people to use fan heaters and air conditioners to regain comfort. To overcome this problem of thermal discomfort in
buildings, we used lightweight concrete such as foamed concrete which is a material that has improved ther(...)

A Modeling Study for Moisture Diffusivities and Moisture Transfer Coefficients in Drying of “Violet de Galmi” Onion Drying
Aboubakar Compaoré, Samuel Ouoba, Kondia Honoré Ouoba, Merlin Simo-Tagne, Yann Rogaume, Clément Ahouannou, Alfa Oumar Dissa, Antoine Béré, Jean Koulidiati
In the present work, the mass transfer characteristics, namely moisture diffusivity and moisture transfer coefficient of “Violet de Galmi” variety of onions were evaluated using the analytical model. Onions were dried in a single layer at different temperatures (40˚C, 50˚C, 60˚C, and 70˚C) and for a relative humidity of drying air of 20%. The(...)

Experimental Alternative to the Determination of the Thermal Dependence of the Complex Modulus of Asphalt Mixes in Dry Tropical Areas
Sidpouita Mathilde Koudougou1,2*, Guy Christian Tubreoumya2,3, David Yemboini Kader Toguyeni1,2, Tégawendé Justin Zaida1
Current pavement design methods do not allow for the reduction of early
deformation of the surface layers of bituminous pavements in the city of
Ouagadougou. Weather conditions combined with traffic, particularly during
heat waves, are factors. The temperature at the surface of the bituminous
pavement can reach 62˚C but the complex mod(...)

Aims: The energy domain is responsible for the production of many gaseous, liquid and solid pollutants, strongly contributing to climate change. The provision of bioclimatic habitats to households is therefore necessary since it will contribute to the reduction of energy consumption. This work consists in making a study of the thermal behavior(...)
