Simulating the Impacts of Information Diffusion on Meningitis Outbreak in West-Africa Using Agent-Based Model
Eric Youl, Mahamadou Belem, Sadouanouan Malo, I. Traoré
This paper describes a model for the simulation of the information diffusion impacts on the spread of meningitis in West-Africa. The approach is based on agent-based modeling to represent explicitly (1) the relationships and interactions among individuals through their social networks and (2) the spread of the disease at individual and system(...)

Accords politiques de gestion des crises au Burkina Faso : origine, caractéristiques et limites
Millogo Missa
Entre 1956 et 1958, la Haute-Volta, aujourd’hui, Burkina Faso, vécut
successivement des crises politiques du fait surtout d’une mise en cause permanente
des accords politiques conclues. Le présent article entend analyser les tenants et les
aboutissants d’une telle attitude dont la dernière manifestation date seulement de
2014. Pour ce fair(...)

On uncertain conical convex optimization problems
Moussa BARRO, Ali OUEDRAOGO, Sado TRAORE
In this paper, we give a necessary and sufficient condition for the equality between the worst value of an uncertain conical convex optimization problem and the value of its robust counterpart. We derive a sufficient condition for strong duality to hold.
uncertain conical convex optimization problems, Fenchel conjugate, worst value, robust value, epigraphical duality, robust strong duality property

Sphère politique et société civile au Burkina Faso dans les mouvements sociaux : Regard sur les conséquences d’une imbrication sur les attentes populaires ?
Missa MILLOGO
Cette étude s’appuie sur une analyse de l’état d’esprit de déception des
populations face à la non-satisfaction de leurs attentes au Burkina Faso de 1960 à nos
jours après les mouvements populaires. En s’appuyant sur des éléments du discours
et de la stratégie des acteurs des partis, de société civile, l’article essaie de
comprendre et d’e(...)

Temperature Preference and Sex Differentiation in African Catfish, Clarias gariepinus
Saïdou Santi, Carole Rougeot, Aboubacar Toguyéni, Vincent Gennotte, Ibrahima Kebe, Charles Mélard
The African catfish Clarias gariepinus has a genetic sex determination system in which high temperature induces masculinization. The thermosensitive period for sex differentiation is short and occurs very early (from 6 to 8 days posthatching [dph]). As young juveniles can encounter high masculinizing temperature (36.5°C) in African water point(...)

Démocratie en Afrique : inefficacité institutionnelle dans la gestion de crises politiques au Burkina Faso : genèse, causes et défis
Missa MILLOGO
Pourquoi les crises politiques sont-elles récurrentes et toujours, ou presque,
résolues au Burkina Faso en dehors des cadres institutionnels constitutionnels prévus
à cet effet ? C’est à cette question que le présent article entend répondre à travers une
analyse d’ouvrages, d’archives et de témoignages. Nous voulons comprendre le
phénomène(...)

Discovering frequent patterns guided by an ontology
Yaya Traore, Cheikh Talibouya Diop, Sadouanouan Malo, Moussa Lo, Stanislas Ouaro
The frequent pattern mining generates a huge amount of patterns and therefore requires the establishment of an effective post-treatment to target the most useful. This paper proposes an approach to discover the useful frequent patterns that integrates knowledge described by the expert and represented in an ontology associated with the data. Th(...)

Contribution to the study of robustness and duality in optimization
Moussa Barro
La dualité et la robustesse sont des outils essentiels dans les processus d'aide à la décision. Cette thèse concerne trois thèmes: dualité en optimisation convexe conique à données incertaines, dualité et régularisation en convexité généralisée, et la maximisation du rayon de robustesse en optimisation continue. Dans la première partie de ce t(...)

On the duality for the sup of two convex function
Moussa BARRO, Ali OUEDRAOGO, Sado TRAORE
In this paper, we extend some qualification conditions in general topological vector space (t.v.s) for the perturbational duality relative to the concept of stability. As an illustration, we apply some of our results to the particular function of the sup of two proper convex functions.
Perturbational duality, convex conjugate, pointwise maximum of two convex functions, zero duality gap

Thermosensitivity of the sex differentiation process in the African catfish, Clarias gariepinus: Determination of the thermosensitive period
Saïdou Santi, Vincent Gennotte, Aboubacar Toguyéni, Charles Mélard, Nadine Antoine, Carole Rougeot
Gonadal sex differentiation in gonochoristic fish is generally labile and under the control of two interacting processes: genetic sex determination (GSD) and environmental sex determination (ESD). Numerous experimental studies deal with temperature induced-sex differentiation in teleosts, but none focused on the African catfish Clarias gariepi(...)

Scheduling an aperiodic flow within a real-time system using Fairness properties
Annie Choquet-Geniet, Sadouanouan Malo
We consider hard real-time systems composed of periodic tasks and of an aperiodic flow. Each task, either periodic or aperiodic, has a firm deadline. An aperiodic task is accepted within the system only if it can be completed before its deadline, without causing temporal failures for the periodic tasks or for the previously accepted aperiodic(...)

Sex determinism in Fish - the Belgian team case studies
Carole Rougeot, Vincent Gennotte, Saïdou Santi, Charles Mélard
This communication is a short presentation of the Belgian team (University of Liège) works on sex determintion in fish. Our works begun during the late 90's with sex determinism studies on tilapia, Oreochromis aureus and O. niloticus, concerning sex reversal procedure with exogenous steroids and temperature during the labile period of sex diff(...)

Cause-of-death Certification in Africa: Analysis of a Model Implemented at the Teaching Hospital of Souro Sanou of Bobo-Dioulasso (Burkina Faso)
Seydou Golo Barro, J. Dufour, M. Somda, Sadouanouan Malo, P. Staccini
Introduction: In Africa, mortality statistics are not reliable due to the low performance of the death registering systems. Our aim is to implement an efficient system. In this article we make a comparison between the existing system model and the new system that will be set up.
Method: UML has been used as the modeling language based on th(...)
