Optimisation des Antennes pour les Applications 5G: Vers une Couverture et une Capacité Accrues
(University of Tlemcen, 2025-06) Berrezoug, Imene Khedoudja
L’évolution des réseaux mobiles, de la 1G à la 5G, a radicalement transformé les modes de communication à l’échelle mondiale. La cinquième génération (5G) marque une avancée technologique majeure, caractérisée par des débits ultra-rapides, une latence très faible, et une capacité de connexion massive. Ces performances permettent le développement de nouveaux usages tels que l’Internet des objets (IoT), les véhicules autonomes, ou encore les villes intelligentes. Au coeur de cette transformation, les antennes jouent un rôle central en tant qu’interface entre les équipements utilisateurs et le réseau. Ce mémoire se propose d’étudier l’évolution des technologies mobiles, les paramètres fondamentaux des antennes, ainsi que les techniques d’optimisation adaptées aux exigences de la 5G. Une attention particulière est accordée aux solutions innovantes telles que le Massive MIMO, le beamforming, et l’utilisation des bandes millimétriques. L’objectif est de mieux comprendre les défis liés à la conception d’antennes performantes et intelligentes, essentielles pour garantir une qualité de service optimale dans les réseaux mobiles de nouvelle génération.

Investigating the Adoption of English as a Medium of Instruction in the Department of Mathematics at the University of Tlemcen: The Case of First-Year Students
(University of Tlemcen, 2026-02-04) Esmaa Benzouba
The year 2023 marked a turning point in the history of Algerian higher education with the introduction of English as a Medium of Instruction (EMI). This exploratory study investigated the implementation of EMI at the University of Tlemcen, focusing specifically on first-year students in the Department of Mathematics. It aimed to identify the challenges that both teachers and students faced while learning and teaching subject content in English and to propose possible solutions to improve its implementation. To achieve these objectives, data were collected through four classroom observations, five interviews with teachers, and 59 student questionnaires. The analysis, conducted using a mixed-methods approach, revealed that both teachers and students had limited proficiency in English, which hindered effective teaching, learning, and communication. However, these difficulties could be addressed through appropriate interventions. The study recommended providing both teachers and students with English for Specific Purposes (ESP) support programs and promoting translanguaging practices to improve outcomes in the EMI context.

L’apport de l’image fixe à la compréhension et la mémorisation du vocabulaire dans une classe du FLE. Cas des élèves de la 3ème année du cycle moyen.
(University of Tlemcen, 2026-02-04) BERRAYAH Amel
This research highlights the importance of still images in the teaching and learning process of reading comprehension and vocabulary acquisition, particularly at the middle school level, specifically in the third year. As a pedagogical tool, still images prove to be particularly effective in enhancing students' understanding and retention of knowledge. It thus emphasizes the importance of appropriately using this tool in foreign language teaching

ستراتيجيات الترجمة الثقافية الحكم العطائية للسكندري نموذجا
(University of Tlemcen, 2026-02-04) شيخ براشد أماني; منصوري وفاء
This study aims to shed light on the concept of cultural translation, highlighting the vital role of the cultural context in the translation process. Indeed, culture cannot be separated from language, as they are two interconnected elements, which imposes significant challenges on the translator, requiring them to seek effective strategies and solutions to ensure an accurate and faithful translation. The study also addresses the impact of globalization in promoting cultural exchange and expanding the influence of translation, which demands that translators deal with increasing cultural diversity and complex challenges. Furthermore, the research, through an applied study, attempted to evaluate the effectiveness of the strategies used in translating cultural content in the book Al-Hikam Al-Ataiyya.
