    Managing innovation and creation innovative entreprise courss
    (2025) Rezala, Aicha
    Innovation management in a company involves a structured approach to generating, developing and implementing new ideas to stimulate growth and competitiveness. It's about transforming creative concepts into tangible improvements, whether it's a new product, a new process or a new service. It's not just about coming up with new ideas, but also about effectively managing the entire innovation process, from initial concept to successful implementation. This process requires a global vision, integrating strategy, culture and operational practices to make innovation an integral and ongoing part of the business. Our understanding of innovation continues to develop, through systematic research, experimentation and the ultimate testing of management practices and experience. So it's a challenge for all of us with an interest in innovation to stay at the forefront of this rapidly evolving, multidisciplinary field. Aimed at Master 2 students who have already acquired a basic knowledge of business management, this handbook tackles these complex concepts to develop the skills needed for success in the professional world, innovation and business creation. It presents business plan approaches for start-up companies and sentence models, which describe the phases of the innovation process, in line with the official program set by the Ministry of Higher Education and Scientific Research, according to the following pedagogical objectives: - - - - Development of the strategic and managerial skills of future entrepreneurial leaders operating in technologically complex national and international environments. Learning the tools and methods for implementing a techno-entrepreneurial or entrepreneurial approach. Help to adopt a more structured approach to innovation management within the company. Develop a business plan for an innovative project.

    Microstructural and micromechanical characterizations of the growing nitrided layer of 30CrMo12 steel
    (IEEE, 2024) Rezala, Aicha
    The need to extend the service life of mechanical parts at a reduced cost has led to the use of thermochemical treatment to ensure surface properties with good core ductility of the treated parts. The objective of this study is to characterize the microstructure and micromechanics of the growing nitrided layer of 30CrMo12 steel frequently used in aeronautical construction. An experimental study on nitriding was conducted in which the steel used underwent a thermochemical nitriding treatment. The treated samples were characterized by optical microscopy, scanning electron microscopy, X-ray diffraction, and microhardness tests. The characterization results showed a considerable improvement in the surface properties (maximum hardness of 1119 HV and wear resistance) of the treated samples. The thermochemical nitriding treatment technique has the power to achieve a nitrided layer of maximum thickness, which increases the resistance to wear and friction as well as mechanical fatigue.
