Essai de typologie des remous politiques en Haute-Volta de 1945 à 1966
MILLOGO Missa, DIPAMA Wend-Vénègda Arsène
Cet article essaie d’analyser la vie politique de la Haute-Volta de 1945
à 1966 à l’occasion de la mise en place du système de la représentation
politique initié à la fin de la deuxième guerre mondiale par la France pour
associer les élites africaines à la gestion des affaires territoriales. Cette
évolution politique a conduit à des re(...)

Identification of Taurine Cattle Breed Based on Convolutional Neural Network
Fulbert Bembamba, Ozias Bombiri, Albert Soudré, Frédéric Ouédraogo, Sadouanouan Malo
Identifying West African taurine cattle breed has become vital since uncontrolled crossing with zebus is jeopardizing their genetic heritage and trypanoresistance capacity. In this study, a computer vision solution is proposed for lobi taurine cattle classification. We implemented a customized Convolutional Neural Network (CNN) on a dataset co(...)

Evaluation du potentiel fourrager des résidus de récolte dans les exploitations cotonnières à l’Ouest du Burkina Faso
Belem A, Ouédraogo-Koné S, Lankoandé YF, Koulibaly B, Sakandé F, Bamogo A, and M Traoré
Dans les exploitations cotonnières à l’Ouest du Burkina Faso, les bovins de trait dont le rôle est capital (énergie, fumure, et d’autres) dans la durabilité du système agricole sont plus affectés au déficit fourrager en saison sèche. Pour y faire face, les résidus de récolte issus des céréales cultivées principalement en rotation avec le coton(...)

Robust optimization for quadratic programs with data uncertainty using the concept of stability radius
Satafa Sanogo, Mohamed Zongo, Moussa Barro, Sado Traoré
In this work, we study an uncertain quadratic optimization problem by using the concept of stability radius. That allows to prove robustness of uncertain quadratic optimization models. Firstly, we determine the stability radius of this problem by applying Ascoli formula. Secondly, we show that its robust counterpart has at least an optimal sol(...)

Influence de la température sur la spermatogénèse chez le tilapia du Nil, Oreochromis niloticus (Linnaeus, 1758) : une synthèse
Abdoul Aziz Tapsoba, Guiguigbaza‐Kossigan Dayo, Saïdou Santi, Rokyatou Sissao, Aboubacar Sourabie, Estèle Pélagie Sanou, Alfred Ouedraogo, Aboubacar Toguyéni
Le tilapia du Nil est une espèce aquacole majeure dont la gamétogénèse est fortement modulée par la température. Ainsi, de nombreux travaux ont été consacrés à l’étude de l’influence des traitements thermiques sur la spermatogénèse chez cette espèce. Le présent article a pour objectif de faire un état des connaissances de l’influence de la tem(...)

On the Occurrence of Different Classes of Solar Flares during the Solar Cycles 23 and 24
Longo Wilfried Sanon, Wendpuiré Ousmane Compaoré, Somaïla Koala, Jean Louis Zerbo
In this study we review the occurrence of different types (A, B, C, M, and X classes) of solar flares during different solar cycle phases from 1996 to 2019 covering the solar cycles 23 and 24. During this period, a total of 19,126 solar flares were observed regardless the class: 3548 flares in solar cycle 23 (SC23) and 15,668 flares in solar c(...)

Entropy solutions for some elliptic anisotropic problems involving variable exponent with Fourier boundary conditions and measure data
Dofyniwassouani Alain Houede, Idrissa Ibrango, Adama Ouédraogo
This paper is devoted to the study of some nonlinear elliptic anisotropic Fourier boundary-value problems, whose prototype is given by
{−Au+g(x,u,∇u)+δ∣u∣p0(x)−2u=μ−divϕ(u)in Ω,Bu+λu=hon ∂Ω,\begin{cases} -Au+g(x,u,\nabla u)+\delta |u|^{p_0(x)-2}u =\mu-\operatorname{div}\phi(u) & \text{in }\Omega,\\\(4pt\) Bu+\lambda u=h & \text{on }\partia(...)

An intelligent research environment on cotton diseases and pests based on a cotton phytosanitary surveillance ontology ontoSYSPARCOTCI.
Téhia Kouaho N'Guessan Narcisse , Malo Sadouanouan , Kouakou Malanno , Bini Kouadio Kra Norbert , Ochou Ochou Germain
User-centred systems need to incorporate solutions to make them easier to use. Based on a domain ontology, our system has an extensive knowledge base that is populated by a semantic web platform that we have built. This knowledge base needs to be queried on demand by users due to the limitations of the search engine integrated into the semanti(...)

Detection of Cotton Diseases by YOLOv8 on UAV Images Using the RT-DETR Backbone
Zakaria Kinda, Sadouanouan Malo, Thierry Roger Bayala
The advancement of deep learning techniques has significantly improved diseases detection on plants remote sensing images. However, this imaging process comes with challenges due to the complex nature of plants remote sensing images abnormalities. The vast range of anomalies in terms of kind, shape, and magnitude of lesions makes it challengin(...)

Detection of Buried IEDs Using Convolutional Neural Networks on Ground Images from Thermal Cameras Embarked on UAVs
Issaka Daouèga, Sadouanouan Malo, Frédéric Ouédraogo
Buried improvised explosive devices (IEDs) are commonly used by terrorist in Burkina Faso. Burial requires the soil to be disturbed, which can be detected effectively using thermal cameras. In this paper, we propose an IED detection approach that consists of discriminating between ordinary soil and deliberately disturbed soil. The approach use(...)
