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(...)

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(...)

Numerical Study of the Effect of Henry’s Constant on the Mechanisms of pesticides Transfer in The Superficial Layers of Hygroscopic Soils
Samuel Ouoba, Auguste A. Soré, Abdoulaye Kaboré and Jean Koulidiati
We describe the transfer mechanisms of pesticides in hygroscopic soils. The work consisted in using Henry’s constants of five pesticides to study the transfer mechanisms. The numerical work consisted to make a soil sample of height h with initial water content w0 and initial pesticide concentration C0 placing it in an ambient atmosphere
