From Light to Income: Solar PV Technology

Abdoulganiour Almame TINTA, Aimé OKOKO, Edmond LANKOUANDE
Sub-Saharan Africa is the region in the world where the deficit in access to electricity is the most significant, with approximately 50% of the population without this basic need. Off-grid electrification, such as the photovoltaic solar system, is an opportunity to substantially improve populations’ access to energy services. In this context, it is important to examine the impact of owning solar PV systems on households’ income. This study focuses on the likelihood of a household with solar panel belonging to the highest income by considering three regions of Burkina Faso. Using primary data covering 6289 households, the entropy balancing method to control for any potential selection bias is performed. We find that owning solar PV has a positive effect on the likelihood of households belonging to the highest income group. Furthermore, the use of solar PV also benefits the poorest populat...

A Novel Reference Model for Intelligent and Comfortable Longitudinal Vehicle Control: Theory, Optimization, and Validation

Flavien H. Somda, Désiré Guel, Kisito K. Kaboré, Antoine Schorgen
This paper introduces a novel reference model for intelligent longitudinal vehicle control, designed to enhance both safety and passenger comfort. The proposed model dynamically adjusts the follower vehicle’s acceleration based on its penetration distance relative to the lead vehicle, ensuring smooth speed transitions and adaptive deceleration. By preventing abrupt braking, the model maintains a safe inter-vehicle distance while reducing passenger discomfort. Key contributions include an analytical derivation of the follower vehicle’s dynamics and a novel formulation of the safety distance using the Lambert W function, enabling precise parameter optimization. A dedicated optimization framework ensures compliance with safety constraints while minimizing excessive acceleration and jerk. The model’s performance is validated through numerical simulations in various driving scenarios, includi...

Automated Detection of Tuberculosis on Chest X-rays Using Artificial Intelligence

Lydie Simone TAPSOBA, Moumouni DJIBO and Relwendé Aristide YAMEOGO
Detecting tuberculosis on X-rays remains complex and challenging for clinicians. In Burkina Faso, the scarcity of radiologists and their heavy workload increase the risk of misinterpretation, particularly in areas with high demand. To address this constraint, we have designed a comprehensive solution based on artificial intelligence, ranging from data analysis to the training of advanced deep learning models, enabling the automatic identification of tuberculosis abnormalities from chest X-rays. In this article, we present our three-step approach for tuberculosis detection, directly inspired by the clinical reasoning of the radiologist. First, we classify the images into those that are normal and those that are not. Next, we segment the images to keep only the pulmonary area. Finally, in this area, we perform a detection of tuberculosis-related anomalies.

FIGURES METONYMIQUES ET CONSTRUCTION METAPHORIQUE DU SAHEL DANS LA GUERRE DES SABLES

Pierrette LINGANI
L’écriture poétique est parfois complexe et hermétique du fait des langages imagés et suggestifs dont la subtilité et la profondeur de sens devraient se scruter dans l’intériorité même de son auteur. La guerre des sables du poète Jacques Guégané se caractérise par ce style suggestif et lyrique à travers une poétisation métonymique qui contribue à la création d’une métaphore du Sahel à partir des souvenirs d’un amour perdu. Comment se manifeste, sous les angles stylistiques et grammatical, le langage poétique guéganéen pour peindre une image du sahel, symbole de souffrance mais aussi de renaissance ? La réflexion vise à analyser la poétisation des textes du corpus tiré du recueil, pour montrer ensuite qu’au-delà du simple lyrisme amoureux, le narrateur rend compte d’une tension entre l’appel sensuel du corps et la conscience douloureuse de l’existence dans la sécheresse sahélienne.
