The pandemic not only revealed the limitations of typical in-person educational experiences but also illuminated the bright light of scalable, inclusive innovation in digital learning. Against this backdrop, Algeria (like many other developing countries) faces enormous challenges when trying to provide modern IT education that fits the growing demand of an increasingly digital workforce, and the competitive demands of a global job market. This thesis proposes a systematic design for a digital academy focused on programming, artificial intelligence (AI), and information technology (IT), specifically in the Algerian context. The platform aims to develop a bridge between traditional education and the need for practical, accessible, and high-quality technical training, by offering a holistic educational ecosystem comprised of an advanced Learning Management System (LMS), interactive course content, real-time assessment, and community-based engagement, all presented in both Arabic and English. The research begins with the literature review that highlights digital learning platforms globally, in the Arab world, and in Algeria; and describes the implications of important strengths, weaknesses, and shortcomings to the online presence contents and their structure, user experience, pedagogical design, and potential improvements to align with the developing needs of labor markets. An analysis of the original platforms was conducted using qualitative and quantitative analyses which provided a detailed comparison of the existing educational systems in Algeria which are unstructured, offer little interactivity and are unsecured for financial transactions, as all educational offerings were relying on social media access links (Facebook, YouTube) or online learning materials (educational resources, references, documents). Informed by the analysis, a rigorous requirements analysis was then conducted, to develop a valid set of functional and non-functional requirements and specifications, while also adapting the recommendations to suit the sociotechnical particularities of the context of Algeria. These included access to limited infrastructure particularly in rural areas, linguistic and cultural diversity including the Arabic and Tamazight languages, and aligning curriculum design with the national strategy for digital transformation and a youth employment strategy. The platform and architecture represent good brief design choices to create the modular, scalable development model discussed in the literature review using the Waterfall development model. The unrestricted multi-featured LMS and the existing online transaction payment system; online and home care tutorials; progress boards and tracking functions; a variety of collaborative features, such as discussion forums, live chat, and the development of multiple types of course offerings in programming and artificial intelligence. Other issues such as access to the LMS; access to multilingual environments; access that is mobile compatible; and ensuring inclusivity and accessibility across a range of users were also resolved. Ultimately, this thesis advocates for a sustainable, locally relevant digital learning model that not only enhances technical education in Algeria but also supports national goals in economic development, digital sovereignty, and human capital formation. The proposed digital academy represents a foundational step towards a more connected, skilled, and VI digitally empowered Algerian society. Future work will focus on platform implementation, pilot testing with real users, and continuous improvement based on feedback and evolving technological trends.Item Open Access A Free Surface Flow under Gravity(Mohamed Boudiaf University of M’sila, Faculty of Mathematics and Computer Sciences, Departement of Mathematics, 2024-06-05) Saadi, Manel; Bounab, Nadia: SupervisorIn this thesis , we have studied numerically a problem of two-dimensional potential flow in a channel with trapezoidal obstacle in the bottom , witch makes an angle = with the axis (xox ) taking into account the effect of gravity but surface tension efforts are neglected.

This study aims to develop a mobile application for mapping forest fire risks in Algeria using Geographic Information Systems (GIS) and the Analytic Hierarchy Process (AHP), with the goal of identifying high-risk areas and analyzing the factors influencing their spread. The application integrates and analyzes various data, primarily climate factors such as temperature and humidity, as well as population density, allowing for the creation of interactive maps that accurately display risk levels. This approach helps decision-makers and relevant authorities improve prevention strategies and resource management effectively, thereby reducing the losses caused by wildfires. The study results showed that combining GISandAHPprovides a precise and effective tool for assessing forest fire risks. Spatial geographic analysis enables the prioritization of interventions and directs efforts towards the most threatened areas. This application proves to be a valuable tool in supporting planning and decision-making processes, making it an essential asset for environmental risk management and forest protection in Algeria.Item Open Access A MULTI-OBJECTIVE OPTIMIZATION ALGORITHM FOR SOLVING ENGINEERING PROBLEMS(Mohamed Boudiaf University of M'sila, 2024) BOUDJAMLINE, Rayhana; CHALABI, Nour elhouda: Supervisor"Human-inspired algorithms are part of metaheuristic algorithms, thus providing a suitable way to find solutions to real-world engineering problems.

These platforms also empower patients, enabling them to schedule appointments online and review their medical data securely. In the rapidly evolving technological landscape, new architectures and approaches have emerged to address the limitations of traditional systems. Multi-tenancy architectures have become a necessity, providing added architectural value for companies with virtualized systems (Cloud, Fog, Edge, etc.) and a valuable skill set for engineers and developers. To address the ambiguity surrounding this architectural trend, our contribution to this work (focused on application rather than research) is based on the use of the highest degree of multitenancy architecture, "unique database," when designing and building a Cloud Software-as-aService (SaaS) application. This approach aims to demystify the conceptual and programming complexities associated with this architectural trend, leveraging a SaaS application tailored for healthcare establishments that supports the demands of its tenants. To realize this distinguished multi-tenant SaaS application, the Laravel Framework has been targeted in this thesis. By adopting a multi-tenancy architecture with a unique database, the proposed healthcare cabin management platform offers a scalable and efficient solution for healthcare providers.Item Open Access AachabOnt: an ontology for alternative medicine(University of M'sila, 2015-06-10) HARKAT, Zohra; Supervisor: BRAHIMI, Mahmoud; Supervisor: Fernini, BelabdelouahabIn recent years, the field of alternative medicine (Phytotherapy) knew a big evolution and became popular for several reasons.
