Robust sensorless control of BLDC Motor using second derivative function of the sum of terminal voltages

This paper proposes a new sensorless control method for the speed and position control of a BLDC Motor. This sensorless drive technique calculates the commutations instants (duration of commutation) by deriving the sum of the terminal voltages of the motor (SigVi). Thus, it is possible to estimate the rotor position (and back EMF of the motor) by only using measurements of the stator line currents and voltages. The implantation of these detectors is easy and cheap. This method is quite robust across variations in stator resistance due to changes in temperature or frequency. With this method the motor can be started without needing the initial position of the rotor. This proposed method is validated through extensive simulations at different speeds, and a very satisfactory performance has been achieved

The phraseological equivalence in Spanish-Arabic translation: the case of the idioms

La presente contribución tiene por objetivo esclarecer el concepto de la equivalencia e identificar los distintos parámetros que rigen su funcionamiento en los planos sistémico, lexicográfico y textual. Asimismo, repasamos los grados de la equivalencia fraseológica (total, parcial, aparente, nula) que se establecen entre dos manifestaciones lingüísticas y culturales tan distintas y distantes como lo son el español y el árabe. Para constatar la existencia de paralelismos fraseológicos entre las dos lenguas objeto de estudio, se presentan ejemplos de locuciones españolas con sus respectivos equivalentes en árabe.This contribution is aimed at clarifying the concept of phraseological equivalence and identifying the different parameters that govern its operation in systemic, lexicographic and textual planes. It also deals with the degrees of phraseological equivalence (total, partial, apparent, null) established between two linguistic and cultural expressions as different and distant as Spanish and Arabic. To verify the existence of phraseological parallelisms between the two languages under study, we will present examples of Spanish idioms with their Arabic equivalents

ACCÈS DES FEMMES AUX FILIÈRES PORTEUSES DE LA FORMATION PROFESSIONNELLE AU MAROC : PÉNALISATION OU AUTO- PÉNALISATION ?

Cet article a pour objectif de répondre à l’un des paramètres qui expliquent la baisse del’activité économique des femmes au Maroc. L’éducation et notamment la formationprofessionnelle est le critère inéluctable qui permettra aux femmes d’atteindre leurautonomisation, à travers l’Emploi.L’OFPPT (Office de Formation Professionnelle et de la Promotion du Travail) propose diversesformations pour préparer des compétences dans différents secteurs porteurs. C’est un levier dedéveloppement de l’activité professionnelle des femmes.Notre étude qualitative menée à Casablanca vise à vérifier les causes des faibles pourcentagesde l’accès des femmes aux filières d’avenir, industrielles et dites masculines.Notre investigation est menée auprès de deux populations, à savoir 5 responsables de formationet 92 femmes stagiaires. Nos guides d’entretien ont démontré que le concept Métier Sexué esttrès ancré. Par contre, L’OFPPT n’intègre aucun critère de ségrégation pour restreindre l’accèsdes femmes aux filières porteuses

Generating functions of binary products of k-Fibonacci and orthogonal polynomials

In this paper, we introduce a new operator in order to derive some new symmetric properties of k-Fibonacci and k-Pell numbers and Tchebychev polynomials of first and second kind. By making use of the new operator defined in this paper, we give some new generating functions for k-Fibonacci and k-Pell numbers and Fibonacci polynomials

POURQUOI LES ENTREPRISES ONT-ELLES BESOIN DU TRAVAIL DES FEMMES ?

Morocco currently has a very low female activity rate (22%), among the lowest in the world. But our country needs all its citizens, our economy needs its women, not only as consumers and expenditure prescribers, but also as producers, creators, developers, workers, employees, executives. In the face of the global upheavals, the rise in living standards, the rise in the level of education, the level of knowledge, and the innovations constantly requested by Marketing, all the population is called to work and produce. Women are an underexploited, if not untapped, wealth in some stagnant areas. Our businesses need each and every one of us to look at a certain level of competitiveness, so that our country can continue to compete decently. Otherwise, our balance of payments will be in deficit, our trade will be unbalanced and we will continue to import rather than manufacture. It is in the collective interest that we must value the work of women in companies, be it industrial, agricultural or service companies, at all levels of the hierarchy, in all regions of Morocco. Laws and attitudes have evolved somewhat, but that is not enough. A boost is needed as our country struggles with international competition and rising global barriers and challenges.Companies need women, whether at the level of workers, employees, managers or positions of responsibility; not to mention those who create their own companies, playing all these roles at the same time; the economy of our country needs businesses, and they need women. Labour is also combined with women

GESTION DE LA DIVERSITE DES GENRES : LEVIER POUR LUTTER CONTRE LES DISCRIMINATIONS EN ENTREPRISE REFLEXIONS SUR L’ETAT ACTUEL DE LA SITUATION AU MAROC

Morocco has a pool of untapped talent: 60% of young graduates are women, only 25% of them work (formal sector) and only 4.3% hold positions of high responsibility in companies (World Bank database, 2015). From there, there is a topic of managing gender diversity as soon as women are underrepresented in the workforce. Gender diversity refers to equal employment opportunities for both sexes without any discrimination. In this perspective, our article will study the HR implications of managing corporate gender diversity while highlighting the potential economic gains from such consideration, based on a review of literature with a comprehensive aim

Passivation and dissolution mechanisms in ordered anodic tantalum oxide nanostructures

Tantalum oxide (Ta2O5) nanostructures exhibit outstanding electrical and optical properties, as well as, high chemical resistance and stability. These materials have great potential for biomedical, catalysis, semiconductors and energy applications due to their large surface area and high specific charge, when arranged in nanoporous or nanotubular morphologies. In order to obtain these structures, an anodization process, which is inexpensive, reproducible and easy to scale up, is used. Yet, depending on the anodization conditions, the formation of a nanoporous or nanotubular layer is difficult to stabilize during the anodization process. In this regard, anodized tantalum oxide nanostructures were produced to understand the effect of the anodization conditions, including electrolyte concentration, potential and time. The nanopores or nanotubes morphologies, their chemical composition and structure were investigated by FIB-SEM, double-corrected TEM-STEM and EDS. We found that it is necessary to have high acid concentrations (mixture of H2SO4 with HF) to be able to form nanoporous or nanotubular structures. Despite the capacity of HF to dissolve and create anodic oxide nanostructures, the amount of H2SO4 concentration in the mixture is very important, leading to a dimple morphology. Furthermore, the increase of the anodization potential/electrical field clearly leads to an increase in the dimples diameter.This research is sponsored by FEDER funds through the program COMPETE -Programa Operacional Factores de Competitividade and by the Portuguese Foundation for Science and Technology (FCT) in the framework of the Strategic Funding UIDB/04650/2020, and UID/EMS/00285/2020 and with a PhD fellowship SFRH/BD/98199/2013.The authors thank the financial support in the framework of HEALTHYDENT -POCI-01-0145-FEDER-030708 and PTDC/CTM-NAN/4242/2014 projects.This work was supported by FCT, through IDMEC, under LAETA, project UIDB/50022/2020.The authors would like to acknowledge that this project has received funding from the EU Framework Programme for Research and Innovation H2020, scheme COFUND -Co-funding of Regional, National and International Programmes, under Grant Agreement 713640
