In this paper, an intelligent neural network-based controller is designed and implemented to control the speed of a permanent magnet synchronous motor. First, the exact mathematical model of PMSM is presented, and then, by designing a controller, we apply the wind turbine emulation challenges. The designed controller for the first time is implemented on a Arm Cortex-M microcontroller and tested on a laboratory PMSM. Since online learning neural network on a chip requires a strong processor, high memory, and convergence guarantee, (...) this article uses the offline method. In this method, first, for different work points, the neural network is trained by local controllers, and then, the trained network is implemented on the chip and used. Uncertainty in the parameters and the effect of load torque as challenges of control systems are applied in the proposed method, and a comparison with other methods is performed in the implementation results section.

After providing an overview of theoretical approaches to ethics, a wide range of relevant practical questions will be explored. The book will cover the issues in greater depth, and in a more critical manner, than other introductory texts.

In the wake of the COVID-19 pandemic, Algerian universities embraced e-learning as a new educational model. The study aimed to uncover the reality of university professors’ engagement with e-learning technologies and the factors influencing the consolidation of that teaching approach. A quantitative field study was conducted at the University of Ghardaia, utilising a questionnaire to survey a sample of faculty members. The findings underscored the critical need for comprehensive training programs to equip professors with the requisite skills for effective e-learning (...) delivery. Moreover, the research highlighted the pivotal role of university administrations in encouraging faculty participation, providing guidance, and establishing a supportive infrastructure conducive to the successful implementation of e-learning initiatives. These insights offer valuable perspectives for optimising the integration of digital learning modalities within the Algerian higher education landscape. (shrink)

This paper deals with the mystical experiences in Virginia Woolf’s artistic creation. Woolf denies any form of modernism that cannot transcend reality. There are moments, where reality is never what it is but a vision — a perspective — whose meaning is beyond the graspable. Reality, thus, becomes un-reality — a halo, and the artist becomes a contemplator — a devotee to such visionary manifestation. Virginia Woolf does not make an exception to this rule. She is par excellence a mystic. (...) The artistic design of her novels, mainly, To the Lighthouse, is of transcendental dimension. Both, Mrs Ramsay’s and Lily Briscoe’s perceptions of life are beyond the palpable: their selves merge within a process of sublimation comparable to that of mysticism. In other words, art (mainly fiction) becomes a process of change from the factual to the transmutable. (shrink)

Lean design and agile design paradigms have been proposed for designing robots; yet, none of them could strike a balance between cost-effectiveness and short duration of the design process without compromising the quality of performance. The present article identifies the key determinants of the mobile robots development process. It also identifies empirically the mobile robot design activities and strategies with the most influence on mobile robot performance. The study identified statistically the mobile robot design activities and strategies most positively correlated (...) with mobile robot performance. The results showed that 65% of typical mobile robot design activities and strategies are affiliated with the lean design paradigm, while the remaining 35% are affiliated with the agile design paradigm. In addition, it was found that 22% of the lean mobile robot design activities and strategies and 25% of the agile mobile robot design activities and strategies, significantly with 99% confidence, are among the design activities and strategies most positively correlated with improving mobile robot performance. A hybrid lean-agile design paradigm is thus proposed. (shrink)

This paper investigates the religiosity/secularity dichotomy in Naguib Mahfouz’s novels, which is shaped by cultural narratives that convey his ideas. It analyzes a defined corpus of Mahfouz’s narratives that articulate his notions of religiosity/secularity. Through an interdisciplinary methodology combining the application of pragmatics, interactional sociolinguistics, and contextual analysis, it aims to determine Mahfouz’s potentiality for perceiving and narrativizing religiosity and secularity in twentieth-century Egypt. It discusses how Mahfouz adopts sociopragmatic techniques to give a bright picture of the secularist discourse but (...) a negative one for the Islamist one presented as inevitably incapable, crude, schizophrenic and idiosyncratic. Mahfouz openly destabilizes the religious/secular dichotomy by juxtaposing religious and secular discourses in his early and later narratives, where he scrutinizes secularity, advocating it as the only way out of and uprooting, religiosity. The adoption of an interdisciplinary framework proves to be theoretically and empirically motivated in order to show how Mahfouz’s narratives reflect their originator’s own beliefs and those of the narrated society, including its value systems.

This study examines the practice of corporate social responsibility (CSR) during COVID-19. Little is known about how organizations practice CSR during acute exogenous crises. Overlooking how CSR practices change during a crisis matters because organizations are compelled into trade-offs that carry implications for their CSR initiatives. Analysis of interview data with CSR managers, from 21 Dubai-based business organizations during COVID-19, uncovers changes in the content and process of CSR during the pandemic. The results show that the practice of CSR underwent (...) a fundamental change in focus as organizations shifted to an employee-centric model of CSR and away from an environmental one. Measures placed on organizations and society to combat the pandemic also led to a recalibration of stakeholder and issue salience, with notable effects on CSR that challenge the capability of the power–legitimacy–urgency framework to anticipate these shifts. We consider the impacts associated with the shift in the content of CSR initiatives and process of their implementation and discuss the implications of the findings for CSR theory, research, policy, and practice.

À travers le présent entretien, Salah Stétié, écrivain au carrefour d’au moins deux traditions culturelles, envisage son rapport singulier à la question de l’entre-deux. Il évoque en particulier le lien très étroit qui l’unit aux civilisations de la Méditerranée ; la question de l’intervalle l’amène à parler du sens de son écriture poétique, de son rapport à la langue et à la traduction. Plus surprenant sans doute est le contexte premier qu’il donne à son exploration poétique, selon une inspiration (...) très orientale : une physique spirituelle de l’énergie — de la danse de l’énergie, au centre de laquelle le poète se tient, à « la source des vertiges ». C’est une entité quasi impersonnelle et insituable qui écrit, à la croisée des dimensions mentales, spirituelles et verbales — et d’un inconscient qui serait beaucoup plus large que le personnel. Cependant, pour Salah Stétié, le poète, loin de ne résider nulle part, développe une « citoyenneté surplombante » qui lui permet de circuler dans toute l’étendue du réel, de l’embrasser dans son ensemble et d’en témoigner sans exclusive. Through this interview, Salah Stétié, writer in the crossroads of at least two cultural traditions, envisages his singular relationship in the question of the in-between. He evokes in particular the very narrow link which unites him with the civilizations of the Mediterranean Sea ; the question of the interval leads him to speak about the sense of its poetic writing, about its relationship in the language and in the translation. More surprising doubtless is the first context which he gives to his poetic exploration, according to a very oriental inspiration: a spiritual physics of the energy—of the dance of the energy, in the center of which the poet stands, near to “the spring of the dizzinesses”. It is a quasi-impersonal and insituable entity who writes, between the mental, spiritual and verbal dimensions—and of an unconsciousness which would be much wider than the personal one. However, for Salah Stétié, the poet, far from livig in Utopia, develops an “overhanging citizenship” who allows him to travel in all the areas of the reality, to embrace them and to testify of them without any exclusive.

This article aims at showing the similarities between the financial and the tech sectors in their use and reliance on information and algorithms and how such dependency affects their attitude towards regulation. Drawing on Pasquale’s recommendations for reform, it sets out a proposal for a constant and independent scrutiny of internet service providers.

Computer and communication technologies created new modes of creating and sharing arts. In this paper, we apply ‘diffusion of innovation’ theory to investigate how artistic content travels in an online social network site called deviantArt, a site designed for sharing user-generated artworks. We first define what innovation corresponds to in such a context, and then discuss how it can be measured with the help of network, image and text analysis methods. We propose to use user-shared resources as relatively easy targets (...) of tracking innovation. (shrink)

The concept of value is so wide that could be considered as synonymous with human life and existence. The human being is engaged in the evaluations of being by doing every act. Life is a value that even its ascetic denial is a kind of valuation. When the human being enters the world, in fact he enters a pre-valued world and many values weighed upon him. To what extent is man capable of emancipating from pre-existing values and to what extent (...) can he succeed in creating value? The complex world today is very similar to the mythical world in which the blind and deaf valuing forces have overwhelmed and conquered human choices. It is here that human choices show a confusing and algebraic procedure, and freedom is as s chain that human being wrap around himself. (shrink)

It is known that when Boabdil, the last of the Abencerrages, left Granada definitively, driven out by the reconquest, he gave a final look at his admirable city and, at that precise moment, sighed deeply. That sigh—el suspiro del Moro—has come down to us through history and after us will no doubt touch and disturb the sensibility of our descendants until the end of time. However, is it really a matter of Boabdil‘s sigh only, or is it the one, coming (...) from Adam, of those who have lost Paradise? Here, Boabdil seems to be one relay among others of that lament issuing from the depths of the species and rising, as regret and never-ceasing nostalgia, to the easily-agitated surface of our ocean of domesticity. Since that first garden, we have been the unloved children of this regret and this nostalgia. The angel with the fiery sword changes nothing: he does not have our memory that, alone, makes us every day a little less original and, in doing so, expels us, making us a little more defenseless than we were when we came out of the void. To remember is obviously to lose oneself, and we are at every moment in this vertiginous situation. As Heidegger said, to remember is to contemplate oblivion. (shrink)

Cet essai relate le cheminement, à travers la Bible, d'une pensée libre, en opposition à la "rétention honteuse, chez les musulmans, pour aller à la découverte de la Torah et des Evangiles" (Youssef Seddik), et à leur "indifférence pour ce qui relève de la connaissance du monde juif, de son passé ou de sa pensée" (Victor Malka). En relevant, à travers l'épopée du peuple "inventeur du dieu unique", les codes qui fondent la morale juive, l'auteur a eu le sentiment de (...) découvrir en YHWH un "Grand Ordonnateur de feuilles de route". Une route rigoureusement balisée, avec ses bornes et ses "haies" de protection - qu'en hébreu on appelle des syagim. Ainsi, après quatre années passées à glaner sur les "terres" du judaïsme biblique, telle Ruth glanant sur les terres de Booz, après avoir étudié plus de cent textes juifs, anciens et contemporains, l'auteur interroge ici le rapport du Juif à son prochain (parent, voisin, étranger, allié ou ennemi). Une découverte. (shrink)

As a conceptual approach in art practice, the female body has represented both a cultural barrier and a source of inspiration throughout art history. The adoption of the female body as an art theme is prevalent across many different artistic movements, using varying conceptual approaches. Women struggle against paradigms of inferiority to this day, though their individual cultural identity varies according to their society’s beliefs and customs – for example, many contemporary Middle Eastern cultures and customs are based on a (...) patriarchal past, when men wielded power over women. Women all over the world experience subjugation to varying degrees in the fields of employment, education, sexuality and reproductive choice. The female body in Middle Eastern societies is a red line that artists are not allowed to cross. Though many Middle Eastern civilizations have dealt freely with the female body, as can be seen in the paintings and sculptures of ancient Egypt, many social and religious factors made the female body taboo in most Middle Eastern cultures. However, on close scrutiny of modern art history in Middle Eastern and Islamic countries, we can identify outstandingly courageous female artists who succeeded in breaking the rules. They chose to express themselves through their own own form of art as an expression of freedom. They chose to use their own bodies as an art medium, which made them pioneers in their countries, and many female artists followed their example. Media art has flourished in Arab countries since the 1990s, especially in Egypt. Many of these female artists distinguished themselves as pioneers, aligning themselves with new art forms and challenging the prevailing stereotypical notion of the female artist at that time. This new mode of female self-expression and identity has developed over time and remains an ongoing process in the twenty-first century. This article considers how Middle Eastern female media artists have struggled to transform stereotypes of women by using their own bodies as an artistic element, and how they have expressed the concept of freedom through their self-body image.

We study some representations of real numbers. We compare these representations, on the one hand from the viewpoint of recursive functionals, and of complexity on the other hand.The impossibility of obtaining some functions as recursive functionals is, in general, easy. This impossibility may often be explicited in terms of complexity: - existence of a sequence of low complexity whose image is not a recursive sequence, - existence of objects of low complexity but whose images have arbitrarily high time- complexity .Moreover, (...) some representations of real numbers that are equivalent from the viewpoint of recursive functionals, are very distinct from the viewpoint of complexity.We make a particular study of representations via continued fractions . We precise exactly what part of information available in the x's dfc is equivalent to the information available in its Dedekinds cut. We show that the sum of two reals whose dfcs are polynomial-time computable may be a real whose dfc has time complexity arbitrarily high.This work confirms that the unique representation of real numbers suitable for the ordinary calculus is via explicit Cauchy sequences of rationals.RésuméNous étudions différentes manières de présenter les nombres réels. Nous comparons ces présentations du point de vue des fonctionnelles récursives d'une part, et de celui des classes de complexité d'autre part.L'impossibilité d'obtenir certaines fonctions sous forme de fonctionnelles récursives est en général facile à établir. Cette impossiblité peut souvent être explicitée en termes de complexité: - il existe une suite de faible complexité dont l'image est une suite non récursive, - il existe des objets de faible complexité mais dont les images sont des objets de complexité arbitrairement grande .En outre, certaines présentations des réels équivalentes du point de vue des fonctionnelles récursives se distinguent nettement du point de vue de la complexité.Nous faisons une étude particulière concernant les développements en fraction continue . Nous précisions exactement quelle est la partie de l'information disponible dans le dfc d'un réel x qui équivaut à l'information disponible dans sa coupure de Dedekind. Nous montrons également que la somme de deux réels dont le dfc est calculable en temps polynomial peut être un réel dont le dfc est de complexité arbitrairement grande.Ce travail confirme que seule une présentation des réels via des suites de rationnels explicitement de Cauchy est adaptée aux calculs avec les réels.

The COVID-19 pandemic caused an unprecedented and highly threatening, constrained, and confusing social and educational environment, we decided to expand the traditional focus of the extraneous load in Cognitive Load Theory acknowledging the psychological environment in which learning occurs. We therefore adapted and implemented principles of the CLT to reduce extraneous load for our students by facilitating their educational activities. Given previous empirical support for the principles of CLT, it was expected that the adoption of these principles might enable our (...) students to cultivate attitudes and skills across multiple domains such as online learning and presentation technologies, implementing and maintaining a “classroom atmosphere” in a virtual environment, participating in discussions among large online groups of students, facilitating group work, providing virtual office hours for students, and proactively planning for upcoming semesters.

Labour issues in global supply chains have been a thorny problem for both buyer firms and their suppliers. Research initially focused mostly on the bilateral relationship between buyer firms and suppliers, looking at arm’s-length and close collaboration modes, and the associated mechanisms of coercion and cooperation. Yet continuing problems in the global supply chain suggest that neither governance type offers a comprehensive solution to the problem. This study investigates collaborative governance, an alternative governance type that is driven by buyer firms (...) setting up a coalition with competitor firms to increase leverage and address the supplier and/or host country-specific labour issues. Based on interviews with managers involved in the establishment and management of such coalitions and supplier firms in the garment industry, we examine the rationale behind collaborative governance and discuss its opportunities and challenges in addressing labour issues in global supply chains.

We investigate quantum features of three coupled dissipative nano-optomechanical oscillators. The Hamiltonian of the system is somewhat complicated due not only to the coupling of the optomechanical oscillators but to the dissipation in the system as well. In order to simplify the problem, a spatial unitary transformation approach and a matrix-diagonalization method are used. From such procedures, the Hamiltonian is eventually diagonalized. In other words, the complicated original Hamiltonian is transformed to a simple one which is associated to three independent (...) simple harmonic oscillators. By utilizing such a simplification of the Hamiltonian, complete solutions of the Schrödinger equation for the optomechanical system are obtained. We confirm that the probability density converges to the origin of the coordinate in a symmetric manner as the optomechanical energy dissipates. The wave functions that we have derived can be used as a basic tool for evaluating diverse quantum consequences of the system, such as quadrature fluctuations, entanglement entropy, energy evolution, transition probability, and the Wigner function.

Virtual screening is the most critical process in drug discovery, and it relies on machine learning to facilitate the screening process. It enables the discovery of molecules that bind to a specific protein to form a drug. Despite its benefits, virtual screening generates enormous data and suffers from drawbacks such as high dimensions and imbalance. This paper tackles data imbalance and aims to improve virtual screening accuracy, especially for a minority dataset. For a dataset identified without considering the data’s imbalanced (...) nature, most classification methods tend to have high predictive accuracy for the majority category. However, the accuracy was significantly poor for the minority category. The paper proposes a K-mean algorithm coupled with Synthetic Minority Oversampling Technique to overcome the problem of imbalanced datasets. The proposed algorithm is named as KSMOTE. Using KSMOTE, minority data can be identified at high accuracy and can be detected at high precision. A large set of experiments were implemented on Apache Spark using numeric PaDEL and fingerprint descriptors. The proposed solution was compared to both no-sampling method and SMOTE on the same datasets. Experimental results showed that the proposed solution outperformed other methods. (shrink)
