Attractivité des places Offshore : analyse de la situation du Maroc en 2021
Cet article vise Ă analyser la notion dâattractivitĂ© en se rĂ©fĂ©rant aux dĂ©terminants qui permettent dâĂ©valuer un pays. En mettant sous la loupe les activitĂ©s dâoffshoring, sâavĂ©rant une matiĂšre dâactualitĂ©, Ă©tant une nouvelle forme des investissements directs Ă©trangers, Ă©mergĂ©es dans le contexte de la globalisation financiĂšre. Ainsi quâil porte sur lâanalyse de la situation dâoffshore marocain en 2021 pour dĂ©terminer ses forces et faiblesses et apporter les propositions dâamĂ©lioration. Notre recherche constitue une problĂ©matique de tout gouvernement qui cherche Ă accroitre sa compĂ©titivitĂ© sur le marchĂ© international et affermir lâattractivitĂ© Ă lâĂ©gard des investisseurs Ă©trangers. Cette Ă©tude a Ă©tĂ© rĂ©alisĂ©e en se basant sur 18 facteurs dâattractivitĂ© sous 4 groupes, Ă©conomiques, politiques, institutionnels et autres, en rĂ©digeant une grille dâĂ©valuation regroupant lâensemble des facteurs relatifs Ă lâĂ©tat dâoffshoring au Maroc en 2021. Dans un objectif dâadaptation, la grille dâĂ©valuation a Ă©tĂ© transformĂ©e en une grille Ă Ă©chelle de 0 Ă 10, nous permettons ainsi dâavoir une vision plus claire sur chaque dĂ©terminant pour constituer le climat dâinvestissement marocain

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 ïŹngerprint 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 dâune 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 sâinscrit dans le cadre des Ă©tudes sociolinguistiques en croisement avec les Ă©tudes de genre. Nous visons, Ă travers cet article, lâanalyse des reprĂ©sentations socio-langagiĂšres du « corps fĂ©minin » chez une judoka et deux pratiquantes de musculation au Maroc et lâimpact 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 socialeâŠ) 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
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
