Le présent travail de recherche constitue la première étape d’un projet visant l’amélioration de la réussite des étudiants en morphographie flexionnelle. Ainsi, il est question en ce premier temps d’identifier les besoins des étudiants nouvellement inscrits au département de fran\c cais en matière d’orthographe grammaticale. À cet effet, nous avons mené deux enquêtes successives à l’université 8 mai 45, Guelma (Algérie). Ce double prélèvement, se basant sur une dictée (les arbres), nous permettra de dresser le profil orthographique des étudiants et de déterminer les zones d’intervention prioritaires nécessitant une intervention urgente.

Les textes d’Isabelle Eberhardt se démarquent par leurs richesses et leurs portés ethnographiques, du fait des détails, descriptions, portraits faits de la société algérienne ou alors maghrébine, de manière générale et de ses habitants, à une époque marquée par le colonialisme. Ils sont aussi un témoignage qui rapporte les traditions, møe}urs, rituels de cette société sensée disparaitre sous les feux de la colonisation. Ils donnent forme et vie à cette identité «nationale » que la France voulait annihiler. Mais ils renseignent également sur l’esprit de curiosité, la minutie dans l’observation de la part de l’auteure qui justifie, en quelque sorte le mode de vie qu’elle s’est choisi.

School textbooks have always had some reflection of home culture or L2 culture in case it is foreign in textbooks or in real-life situations, interactions that take place between languages and their cultures have always contributed to cultural enrichment, the present study is an attempt to encourage intercultural dialogue between Mediterranean countries. Indeed, through the analysis of the literary texts proposed in Algerian second school textbooks, we aim to identify the Mediterranean cultures manifested using a didactic approach.

Since the difficulties that we are facing during all the activities, cooperative learning considers as the effective strategy to overcome these difficulties as well as improving the pupils’skills. This study stresses on the performance and organize this type of learning which led to the exchange and interaction between the group members as well as to its evaluation that allows pupils to know their abilities and their weaknesses Which give them the chance to suggest solutions for the coming collaborations that make them participate in their scientific track and make them self-reliant ones. Face aux difficultés rencontrées lors des différentes activités, l’apprentissage coopératif se considère comme une stratégie efficace pour surmonter ces difficultés et améliorer les compétences des élèves. Ce travail se focalise sur le fonctionnement et l’organisation de ce type d’apprentissage, qui favorisent l’échange et l’interaction entre les membres du groupe. De plus, sur son évaluation, qui permet aux élèves de savoir leurs forces et leurs faiblesses et de proposer des solutions pour les coopérations à venir, ce qui les implique dans leur processus d’apprentissage et les rendre plus autonomes.

During the last years, in industrial process control, requirements for Continuous Emission Monitoring (CEM) have increased significantly. Most plants are investing in CEM systems in order to burn waste, obtain ISO 14000 and 18001 certification to protect operator's life. In this work, our approach describes development of a novel internet and fuzzy-based CEM system (IFCEMS). This system contains operator's stations for the bag filter's automation system and monitored using Internet. The object of the present installation consists of a suction ventilator, a bag filter and a system for collecting and evacuating the dust. To optimize the running of the bag filter workshop and ensure continuous control, the process based on one of the most powerful Artificial Intelligence techniques which is fuzzy logic involves the removal or filtration of smoke from the kiln and/or cement mill with control of temperature and pressure of the fumes.

A successful osseointegration involves the simultaneous optimization of the primary stability of the implant and the minimization of interfacial stresses bone - implant. In this context, the modeling of these stresses reports a great interest for researchers in last decades.The aim of this work is to study the effects of geometric parameters of a new model of titanium dental implant on the evolution of interfacial stresses bone /implant. For this, a dental implant of the second premolar in the lower jaw was considered, with different diameters, thread pitches and different thread forms. The profile of the interfacial stresses was presented for each case study, the results show a great similarity in the areas concerned, cortical bone, threaded region and cancellous bone, with the results obtained in the literature for other types of geometries.

In this paper, we propose a vector control of a doubly fed induction generator (DFIG) for variable speed wind power generation. The model is developed based on the dual powered generator for the control of the active and reactive powers. Several studies are carried out to test their operation under different wind conditions. The results have shown good performances of the wind energy converter system operate under wind variations with indirect vector control strategies.
