    Cet article vise Ă  analyser la notion d’attractivitĂ© en se rĂ©fĂ©rant aux dĂ©terminants qui permettent d’évaluer un pays. En mettant sous la loupe les activitĂ©s d’offshoring, s’avĂ©rant une matiĂšre d’actualitĂ©, Ă©tant une nouvelle forme des investissements directs Ă©trangers, Ă©mergĂ©es dans le contexte de la globalisation financiĂšre. Ainsi qu’il porte sur l’analyse de la situation d’offshore marocain en 2021 pour dĂ©terminer ses forces et faiblesses et apporter les propositions d’amĂ©lioration. Notre recherche constitue une problĂ©matique de tout gouvernement qui cherche Ă  accroitre sa compĂ©titivitĂ© sur le marchĂ© international et affermir l’attractivitĂ© Ă  l’égard des investisseurs Ă©trangers. Cette Ă©tude a Ă©tĂ© rĂ©alisĂ©e en se basant sur 18 facteurs d’attractivitĂ© sous 4 groupes, Ă©conomiques, politiques, institutionnels et autres, en rĂ©digeant une grille d’évaluation regroupant l’ensemble des facteurs relatifs Ă  l’état d’offshoring au Maroc en 2021. Dans un objectif d’adaptation, la grille d’évaluation a Ă©tĂ© transformĂ©e en une grille Ă  Ă©chelle de 0 Ă  10, nous permettons ainsi d’avoir une vision plus claire sur chaque dĂ©terminant pour constituer le climat d’investissement marocain

    Coherence in amalgamated algebra along an ideal

    Full text link
    Let f:A→Bf: A\rightarrow B be a ring homomorphism and let JJ be an ideal of BB. In this paper, we investigate the transfert of the property of coherence to the amalgamation A⋈fJA\bowtie^{f}J. We provide necessary and sufficient conditions for A⋈fJA\bowtie^{f}J to be a coherent ring

    Self-Partial and Dynamic Reconfiguration Implementation for AES using FPGA

    This paper addresses efficient hardware/software implementation approaches for the AES (Advanced Encryption Standard) algorithm and describes the design and performance testing algorithm for embedded system. Also, with the spread of reconfigurable hardware such as FPGAs (Field Programmable Gate Array) embedded cryptographic hardware became cost-effective. Nevertheless, it is worthy to note that nowadays, even hardwired cryptographic algorithms are not so safe. From another side, the self-reconfiguring platform is reported that enables an FPGA to dynamically reconfigure itself under the control of an embedded microprocessor. Hardware acceleration significantly increases the performance of embedded systems built on programmable logic. Allowing a FPGA-based MicroBlaze processor to self-select the coprocessors uses can help reduce area requirements and increase a system's versatility. The architecture proposed in this paper is an optimal hardware implementation algorithm and takes dynamic partially reconfigurable of FPGA. This implementation is good solution to preserve confidentiality and accessibility to the information in the numeric communication

    Robust ïŹngerprint recognition approach based on diagonal slice of polyspectra in the polar space

    Although fingerprint recognition is a mature technology and nowadays commercial state-of-the-art systems can be successfully used in a number of real applications, not all the problems have been solved and the research is still very active in the field. This paper presents a new approach for estimating the shift and rotation parameters between fingerprint images stored in the dadabase that operates in the third-order frequency-domain measure called the auto-bispectrum, which, allows us to estimate the shift and the rotation separately. The diagonal slices and their spectra of auto- and cross-bispectrum are proposed. The rotation parameters are estimated from the remaining polar sampled the third-order spectrum using cross-correlation, and then, after compensating for rotation, we may easily estimate the translational component, e.g., by using phase correlation.Experimental evidence of this performance is presented, and the mathematical reasons behind these characteristics are explained in depth. We compare our approach in a simulation to other frequency-domain fingerprint recognition algorithms. We find that our algorithm can better estimate shift and rotation parameters than the other methods

    Le corps fĂ©minin dans le sport : quelles reprĂ©sentations socio-langagiĂšres ? les cas d’une judoka et deux pratiquantes de musculation

    Nous disons notre corps et notre corps nous fait dire nos rapports avec la vie sociale. Une Ă©nonciation, Ă  notre sens, reprĂ©sentative de notre travail de recherche qui s’inscrit dans le cadre des Ă©tudes sociolinguistiques en croisement avec les Ă©tudes de genre. Nous visons, Ă  travers cet article, l’analyse des reprĂ©sentations socio-langagiĂšres du « corps fĂ©minin » chez une judoka et deux pratiquantes de musculation au Maroc et l’impact du regard de la sociĂ©tĂ© sur le corps fĂ©minin dans les activitĂ©s sportives.   Ces reprĂ©sentations socio-langagiĂšres du corps fĂ©minin dans le sport se basent sur du sens (culture commune, imaginaire collectif, socialisation, pression sociale
) pour produire du sens (maintenir, dĂ©construire ou crĂ©er des normes, des idĂ©es ou des dogmes (culte du corps parfait). Ainsi, le corps de la femme fait objet de reprĂ©sentations socio-langagiĂšres multidimensionnelles et modulables selon diffĂ©rentes variantes, parmi ces variantes nous mentionnons :  sexe biologique, genre sociale, Ăąge, socialisation, culture, religion, espace, niveau social/intellectuel etc. Dans cet article, nous cherchons Ă  rĂ©pondre aux questions suivantes : Comment pouvons-nous apprĂ©hender les reprĂ©sentations socio-langagiĂšres du « corps fĂ©minin » dans le sport Ă  travers la double optique des Ă©tudes sociolinguistiques et des Ă©tudes de genre ? et comment le conditionnement social, basĂ© sur la nature biologique/anatomique, cadre-t-il les perceptions et les reprĂ©sentations sociales du corps fĂ©minin dans le sport

    An initialization scheme for supervized K-means

    Get PDF
    Over the last years, researchers have focused their attention on a new approach, supervised clustering, that combines the main characteristics of both traditional clustering and supervised classification tasks. Motivated by the importance of the initialization in the traditional clustering context, this paper explores to what extent supervised initialization step could help traditional clustering to obtain better performances on supervised clustering tasks. This paper reports experiments which show that the simple proposed approach yields a good solution together with significant reduction of the computational cost
