Proposal of Models for Global Solar Radiation Estimation in Burkina Faso
Ladifata Mogmenga, Goumwêndkouni Gilbert Nana, Salifou Ouédraogo,Thierry Sikoudouin Maurice Ky, Bouchaib Hartiti, Sié Kam, Joseph Dieudonné Bathiebo.
The solar data used to size installations for energy needs are most often oversized. The data used are either old or suffer from the effects of climate change or from data extrapolated to a whole region. For a country with a strong sunshine all year round, it is good to compare the many models that exist to find the most suitable for the count(...)

A linear system with Fresnel reflectors as a concentrator was designed, built,and tested for solar cooking. It consists of 17 reflectors (blades) made of 1 mmthick aluminum sheet metal, mounted on a metal support to ensure theiralignment. The system has a geometric concentration of 17. The system is dif-ficult to operate because the blades mus(...)

THERMAL PERFORMANCE OPTIMIZATIONS OF A HEMISPHERICAL SOLAR COOKER WITH ALUMINUM SHEET CONCENTRATORS: APPLICATION TO FOOD COOKING
Ladifata Mogmenga, Bouto Kossi Imbga, Thierry, Sikoudouin Maurice Ky, Salifou Ouedraogo, Sie Kam, Joseph Dieudonne Bathiebo.
Cooking is a method of transforming food by exposing it to heat. Solar cookers allow us to cook food using the heat generated from the sun's rays. In this work, we present an experimental study of a hemispherical solar cooker tested with and without glazing. In the context of sustainable development, in order to reduce environmental impact, th(...)

The AMBRE Project: Line-broadening and stellar rotation of ESO/FEROS archived spectra
F. Bado, P. de Laverny, Z. Kam, A. Recio-Blanco, P. A. Palicio and J. Koulidiati
Context. Stellar rotation is a fundamental parameter in studies of the formation and evolution of stars. However, large homogeneous catalogues of rotational velocities derived from high-resolution stellar spectra are still lacking.
Aims. The main objective of this work is to determine the line-broadening parameter (Vbroad), which is a proxy f(...)

Determination of the optimal operating distance of a solar PV module under the influence of the electromagnetic field
V. de Dieu Bokoyo Barandja, Idrissa Sourabie, Mamoudou Saria, Eric Simonguy, N. L. Privace M'bouana, Christian Kenfack-Sadem, Ramatou Saré, E. Wendsongré Ramdé, Martial Zoungrana, Issa Zerbo
The effect of an electromagnetic field (EMF) on the various electrical parameters of a photovoltaic (PV) solar cell or PV module is not uniform. A high intensity or proximity to an electromagnetic field increases the photoelectric current, while the photovoltage has the opposite effect. Thus, for certain electrical parameters, the EMF can be c(...)
