Gabon's results at the CAMES CCI 2023? A wealth of information to improve teaching and research

Making data available (infor mation) for private or public access (e.g. on the Internet) is a lengthy process. Data needs to be created (collection, measurement, sampling), organized (database, files, folders), reduced in size (compression, archiving) and disseminated (emailing, website access). The way in which disseminated data are presented (data history, file type, data formatting) can facilitate or complicate their future exploitation. For various reasons, we decided to study the results file corresponding to teachers and researchers promoted at the 23rd session of the CAMES CCI. In our case, we restricted ourselves to those promoted in Gabon in July 2023. A series of procedures, including simple statistical analyses using pivot tables in MS Excel 2021, enabled us to obtain some results. Significantly more teacher-researchers than researchers were promoted. Assistant professors were the most numerous. Profiles in Humanities and Languages accounted for the lion's share, with 50% of those promoted rated A. Historic establishments were the most successful. Regardless of rank, category, establishment, rating or CTS, women promoted in Gabon generally represented only a third of men. We have attempted to justify the results observed and, above all, to propose remedial actions, in particular those aimed at improving the current presentation of CAMES data.  Keywords: Data access, information processing, statistical analysis, professional career, African and Malagasy Council for Higher Education (CAMES), Inter-African Consultative Committees (IACC)

Gabon's results at the CAMES CCI 2023? A wealth of information to improve teaching and research

Rendre des données disponibles (information) en accès privé ou public (par exemple sur internet) est un long processus. Il faut créer les données (collecte, mesure, échantillonnage), les organiser (base de données, fichiers, dossiers), réduire leur taille (compression, archivage) et les diffuser (envoi par email, accès via site web). La manière dont les données diffusées sont présentées (historique des données, type de fichiers, formatage des données) peut faciliter ou compliquer leur exploitation future. Diverses raisons nous ont poussés à étudier le fichier de résultats correspondant aux enseignants-chercheurs et chercheurs promus à la 23ème session des CCI du CAMES. Dans notre cas, nous nous sommes restreints aux promus du Gabon, en juillet 2023. Un ensemble de procédures, notamment de simples analyses statistiques, via des tableaux croisés dynamiques sous MS Excel 2021, nous ont permis d’obtenir quelques résultats. Il y a eu nettement plus d’enseignants-chercheurs que de chercheurs promus. Les Maîtres assistants étaient les plus nombreux. Les profils en Lettres et Langues se sont taillés la part du lion. 50% des promus ont eu la cote A. Les établissements historiques ont connu le plus de réussite. Peu importe le grade, la catégorie, l’établissement, la cote et le CTS, les femmes promues au Gabon ne représentaient en général que le tiers des hommes. Nous avons tenté de justifier les résultats observés et surtout de proposer des actions curatives, en particulier celles visant à améliorer la présentation actuelle des données du CAMES.

Adaptive hysteresis current control of active power filters for power quality improvement

In power grids, the active power filter (APF) is an important device for compensation of harmonic pollution and reactive power caused by nonlinear loads. However, the control method has a significant influence on the APF performance in eliminating the distorted currents. Henceforth, this paper explores the control of shunt active power filters based on: 1) instantaneous power control strategy (p-q Theory) for extracting the reference currents for APF, and 2) adaptive hysteresis current control (AHCC) strategy for performance evaluation. Different case studies are carried out such as, balanced/unbalanced source with balanced/unbalanced load, distorted source with balanced load in Matlab®/ SimPowerSystems. Simulation results highlight the effectiveness of the proposed control method
