Authors: Marzouk Khairallah Salwa , Mhiri Hatem , EL Golli Salem , Le Palec Georges , Bournot Philippe
Published: February 2024

Une étude numérique portant sur un écoulement de type jet plan pulsé anisotherme en régime turbulent a été menée afin de déterminer l'influence de plusieurs paramètres tels que le nombre de Strouhal et l'amplitude de la pulsation sur les grandeurs dynamiques et thermiques de l'écoulement. Les jets pulsés sont des écoulements non permanents, à un instant donné, les champs de vitesse et de température vérifient l'équation de continuité, les équations de conservation de la quantité de mouvement et de l'énergie. La fermeture du système d'équations obtenu est assurée par le modèle de l'énergie cinétique turbulente k et du taux de dissipation de l'énergie cinétique turbulente e, dit modèle . La résolution des équations associées a leurs conditions aux limites est effectuée après adimensionnement par une méthode aux différences finies. Le maillage utilisé est uniforme dans la direction transversale et non uniforme selon la direction longitudinale. Par contre le pas de calcul temporel adopté est constant. Le code de calcul numérique élaboré nous a permis d'établir les caractéristiques dynamiques et thermiques instationnaires d'un écoulement de type jet plan pulsé en faisant varier la fréquence et l'amplitude de pulsation. Les résultats obtenus nous permettent de constater que la pulsation accélère le développement initial du jet et améliore la diffusion, l'entraînement ainsi que l'échange thermique avec le milieu environnant dans les premiers diamètres. Loin de la source d'émission, elle ne modifie pas les paramètres de l'écoulement.
Etude de l'influence du temps de réponse de la sonde d'interférence en mesures simultanées par thermo - anémométrie a fil et film chauds dans un mélange air/hélium
Authors: Soudani Azeddine , Bougoul Saadi , Harion Jean-Luc
Published: February 2024

l'influence de la réponse dynamique de la sonde d'interférence est étudiée dans le cas des mesures simultanées des valeurs moyennes et fluctuantes de vitesse et de concentration dans un mélange air/hélium en écoulement turbulent. En effet, un critère de choix des instruments de mesure portant sur une meilleure réponse en fréquence, est primordiale. On montre dans la présente étude que l'écartement des l'iso-concentrations est bien provoqué par la différence entre les réponses du fil et du film. En effet, les points situés loin de la courbe attendue correspondent principalement à un déficit en tension du film pendant la phase d'augmentation des tensions des deux éléments. Ceci est d'autre part confirmé par les spectres de tensions réalisés pour =0,24.
Réduction des étalonnages multiples en mesures simultanées dans une couche limite turbulente d'un mélange air - hélium
Authors: Soudani Azeddine , Bougoul Saadi , Harion Jean-Luc
Published: February 2024

Les mesures simultanées par thermo-anémométrie de plusieurs grandeurs physiques d'un fluide en écoulement turbulent, nécessite l'emploi d'autant de sondes qu'il y a de variables. Un étalonnage est préalable à toute utilisation de ces capteurs pour des mesures. Cet étalonnage est fondé sur des lois d'ajustement, réalisées généralement par des méthodes classiques d'interpolation linéaire, des régressions polynomiales, des fonctions splines ou encore par des réseaux de neurones artificiels. Il permet d'établir le lien univoque entre les sorties de ces capteurs, données sous forme de tensions, et les paramètres physiques de l'écoulement à mesurer. Suivant la forme du réseau d'étalonnage obtenue, la précision de ces méthodes peut être extrêmement sensible aux degrés des polynômes d'ajustement et peut présenter ainsi des erreurs importantes d'interpolation. Il est donc nécessaire de tester systématiquement les paramètres d'ajustement pour chaque application. On montre à travers cette étude que, les méthodes de génération de grilles cartésiennes et de dépouillement de mesures, utilisant des régressions polynomiales et des interpolations linéaires, sont beaucoup moins précises que celles utilisant les fonctions splines et les réseaux de neurones artificiels. Les résultats obtenus montrent aussi que l'utilisation d'une surchauffe plus forte pour l'élément amont que l'élément aval de la sonde apporte, en général, une meilleure précision lors de la génération des grilles.

Published: February 2024

La comparaison de deux géométries du réseau du caloporteur d'un capteur plan classique, nous oblige à mettre en évidence l'influence des pertes par convection sur le bilan optothermique de ce capteur. Partant des caractéristiques optiques et géométriques du capteur, des caractéristiques hydrauliques du fluide caloporteur, nous évaluons avec le maximum de précision les différentes composantes du bilan thermique en tenant compte notamment des gradients de température dans l'absorbeur. Ce travail a été mené avec de l'eau pressurisée comme fluide caloporteur. Notre étude théorique a été menée en utilisant un programme de calcul développé au laboratoire se basant sur la méthode des différences finies. Ce programme a été validé par les résultats expérimentaux dans les mêmes conditions météorologiques. Le convertisseur type serpentin a été choisi.

Published: February 2024

La pile à combustible (PAC) est connue depuis longtemps comme un convertisseur d’hydrogène en énergie (électrique + thermique) possédant de très bons rendements, les recherches sur cette technologie se développent partout dans le monde de manière considérable. Les raisons sont bien connues: la réponse aux contraintes environnementales, aux problèmes posés par la production centralisée d’électricité, la nécessité d’avoir des alternatives énergétiques (vecteur hydrogène) et certaines exigences technologiques spécifiques telles que les applications spatiales, sous-marines, électroniques portables, alimentation électrique de sites isolés et de microsystèmes. Il est certain que nous assisterons dans les prochaines décennies à l’émergence de la filière hydrogène dans notre vie quotidienne comme vecteur énergétique. Le choix de la technologie des piles à combustible à membrane échangeuse de protons (PEMFC) est implicite vu les performances intéressantes (faible poids, robuste, électrolyte solide, démarrage rapide, large gamme de puissance de 1 W à10 MW, etc.). Il est donc important de pousser encore plus loin les efforts de recherche/développement autour de cette technologie pour pouvoir la maîtriser et étendre son application. Cet article présente les résultats de la modélisation de la cinétique électrochimique et la production électrique des piles à combustible PEMFC alimentée directement en gaz pur (hydrogène et oxygène) et la validation expérimentale grâce à une base de données établie au niveau du ‘’Laboratoire d’Hydrogène en Réseau – CDER‘’, dans le but d’exploiter et d’améliorer les modèles électrochimiques existants.

Authors: Géorgakèllos Dimitrios A.
Published: February 2024

Ce travail présente les éléments nécessaires pour la gestion d’un projet de microcentrale hydroélectrique. Actuellement, l’hydroélectricité représente la première source mondiale de production d’énergie renouvelable. Toutefois, des grandes et nouvelles stations hydroélectriques ne vont plus être construites que très rarement. Mais il y a un potentiel considérable pour les micro hydroélectriques. Par conséquent, son développement actuel et futur est essentiellement basé sur les Petites Centrales Hydrauliques (PCH). Dans ce cadre, le but de ce travail est de renfermer les éléments nécessaires pour aborder un projet de microcentrale hydroélectrique en présentant l’information fondamentale sur une PCH typique grecque. Selon la présentation ci-dessous, ces éléments sont le potentiel exploitable qui se détermine par les valeurs du débit et de la chute, les ouvrages de génie civil (ce sont le barrage et les ouvrages des dérivations), le choix de matériel (ce sont surtout la turbine et le générateur) qui est très important car il doit permettre d’utiliser au maximum le potentiel exploitable et les conditions techniques du raccordement au réseau national.

Authors: Kasbadji Merzouk Nachida , Merzouk Mustapha
Published: February 2024

Le potentiel énergétique éolien utilisable de la partie ouest des Hauts Plateaux algériens est estimé en considérant deux sites représentatifs, à savoir: Tiaret et El Bayadh. Les distributions statistiques sont établies pour tous les mois en traitant les données de dix années consécutives. Les puissances utiles et utilisables ont été estimées mensuellement en considérant les limites de 3 éoliennes du commerce de 100 kW, 600 kW et 850 kW de puissance nominale respective. Les quantités d’eau que l’on peut pomper quotidiennement ont été estimées pour les mois extrêmes (janvier et juillet). Les résultats montrent que les performances de la machine dépendent du site et de la période et que multiplier la puissance nominale d’une éolienne peut s’avérer sans conséquence sur la puissance utilisable et donc le débit d’eau pompée.

Authors: Kumar Sameer , Bargavi Dr. S.K.Manju
Published: February 2024

With artificial intelligence (AI) continuing to pervade many aspects of society, it is critical to comprehend the dynamics of trust in AI decision-making and human-AI interaction. This study explores the many facets of trust and looks at how important it is in influencing user attitudes, actions, and the general effectiveness of AI systems. In order to understand the complex interactions between intelligent machines and people, the research incorporates multidisciplinary viewpoints from the fields of psychology, human-computer interaction, and ethics. The first area of inquiry is what influences the creation of first faith in AI. [1]We investigate how consumers' desire to trust AI-driven technology is influenced by system transparency, explain ability, and user experience through empirical study. The creation of design concepts intended to build a foundation of trust in AI systems is informed by insights gained at this stage. The second aspect of the study focuses on how trust changes over time in extended encounters between humans and artificial intelligence. We study the dynamics of trust-building and erosion by monitoring user experiences and system performance. This helps to clarify the critical points and factors that affect the trust's trajectory. This long-term viewpoint aids in the creation of adaptable artificial intelligence systems that can adapt to changing user demands and address issues with trust. The third line of investigation concerns the function of trust in AI-influenced decision-making processes. We evaluate the extent to which users depend on AI-generated insights and the influence of trust on decision outcomes using experimental scenarios and real-world case studies. This stage clarifies the fine balance needed to maximise the collaboration between AI and humans and emphasises the significance of matching AI suggestions with user values. The research concludes with an examination of the consequences of trust in AI for wider societal contexts, with a focus on ethical issues. We look at accountability frameworks, the potential fallout from blind trust, and the moral obligations of AI engineers in creating reliable systems. In order to foster a symbiotic relationship between humans and intelligent systems in a world increasingly driven by AI, this thorough investigation of the role of trust in human-AI interaction and decision-making ultimately aims to provide actionable insights for the design, implementation, and governance of AI technologies.

Practical recommendations for performing research in closed youth care settings

Performing research in a forensic setting poses certain challenges, especially when it pertains to complex or sensitive research designs. As a result, studies often end up with small sample sizes which limits reliability and generalizability of the results, and consequently narrows their potential for new insights. This article provides several practical recommendations for successful scientific research in youth forensic settings, organized into five steps: study design, setting up, recruiting participants, collecting data, and rounding off the project and communicating results. These tips help researchers carry out their protocols, collect sufficient amounts of good-quality data, and maintain good relations with the institutions. The recommendations are based on experiences from the Study Consortium for Reattributional E-training Effectiveness and Neuroprediction (SCREEN) study, a longitudinal multi-center project in the juvenile forensic setting in the Netherlands that involved 400+ detained youth. This paper intends to aid researchers in setting up and performing research in different closed youth care settings.
Can ocular fixations modulate the perception of a bistable logo?
Authors: Rodríguez-Martínez Guillermo
Published: February 2024

Bistable logos accept two different interpretations, where each interpretation can be conditioned by the area of the image that is being observed. Thus, ocular fixations can affect their final perception. To determine if the eye fixation areas influence the perception, 20 volunteers observed a bistable logo in front of a fixed eye-tracker, reference Tobii T-120. The results indicate that the reported percepts are related to ocular fixation areas. It is concluded that there are areas that affect the identification of the possible percepts of the bistable logo, which leads to essential considerations for graphic designers to optimize graphic brand communication.

Examınatıon of famous use ın televısıon advertısements wıth electroencephalogram (EEG)
Authors: OYMAN Turgay
Published: February 2024

Objective: The research aims to analyze the changes in brain activity of emotions caused by the use of celebrities in television (TV) commercials using Electroencephalography (EEG). It tries to determine the positive (liking, having fun) and negative (disliking, bored) emotions of the audience with Electroencephalography (EEG).
Method: We tried to determine the emotional states of the volunteers who watched the commercials by examining the theta activities in different parts of their brains. A questionnaire was applied to 36 volunteers in our research before and after watching the advertisements. EEG recordings were made while the volunteers were watching the commercials. Theta activities obtained as a result of EEG recording were tabulated as duration. The hypotheses were tested by using the responses of the volunteers to the questionnaires and the EEG results comparatively with frequency tables and the Independent-Samples T test.
Originality/Relevance: Both the preparation and broadcasting of TV advertisements, which have a very important place in marketing communication, can be very costly for businesses. Neuromarketing, which encourages interdisciplinary work, allows the use of methods, designs, theories and technologies used in neuroscience in areas such as marketing and advertising. In this study, with the help of EEG, one of the techniques used in neuromarketing, it has been tried to determine the emotions that the advertisements will create in the audience. It is among the few experimental studies conducted in Turkey.
Results: Although EEG results shows that the activity intensity in the left hemisphere and left frontal lobe was higher than the activity intensity observed in the right hemisphere and right frontal lobe in the volunteers watching TV commercials, and the activity intensity in the left hemisphere and left frontal lobe in the volunteers where the advertisements created positive emotions, and the activity intensity in the left hemisphere and left frontal lobe in the volunteers, where the advertisements created negative emotions, statistically, as our hypotheses suggest, no significant activity difference was observed.
Theoretical/methodological contributions: The research contributes to the scientific community by deepening the knowledge on neuromarketing, which is under development in Turkey as in many countries. It also provides clues about the use of neuromarketing in advertising research. This study will contribute to the preparation of effective advertisements by understanding the emotions of the audience.
Managerial implications: Research findings can help businesses and advertisers prepare more effective commercials, thereby saving businesses costs.

Published: February 2024

Privacy protection ensures that individuals have control over personal data, preventing abuse and preserving trust in the use of online services. In the “Digital Era”, where the collection, storage and processing of personal information have become ubiquitous, data privacy emerges as a relevant topic. In this sense, laws were created, such as the General Data Protection Law (LGPD) in Brazil and the General Data Protection Regulation (GDPR) in Europe, to control privacy and the processing of personal data. The article presents a comparative analysis of 2 (two) data privacy mechanisms, the Zero-Knowledge Proof (ZKP) and Ring Signatures, used in Blockchain, aiming at the legal and regulatory implications with the LGPD and GDPR. The comparative study between ZKP and Ring Signatures highlights the flexibility of ZKP in various contexts, including voting and secure authentication systems, while Ring Signatures offer significant advantages in terms of scalability and efficiency in systems where subscriber anonymity is considered fundamental. Furthermore, the legal and regulatory implications of the ZKP are discussed, mainly in relation to LGPD and GDPR. Finally, the article concludes that the comparative analysis offers insights into applications, challenges and legal and regulatory implications, particularly in relation to data privacy and compliance with regulations such as LGPD and GDPR.

From this, the following question arose: How do excessive work and moral harassment influence workers' mental health within the work environment? To carry out this study, we followed the methodological path in which theoretical-bibliographical research was used, in order to critically and socio-historically understand the phenomenon of work and working hours, as well as their construction in society over time. . The research was carried out by searching for works by authors who contributed to the topic on the academic platforms Google and Sciello using the descriptors: working hours; mental illness; excessive working hours; and moral harassment at work. We carry out brief analyzes of work, mental illness in the workplace, its impacts on the worker, laws that guarantee worker assistance, mental illness, moral harassment and its relationship with excessive working hours, debating how the hostile environment interferes in good professional development and lists how to act in order to face these issues. Finally, we understand that most workers do not realize that they are in the middle of a game of interests, influenced to always be in competition with others and ensuring the best performance of the company.

Reflect on the management of nursing care from the creation of images by university nursing students. Exploratory-descriptive study with a qualitative approach carried out with twenty-four university nursing students in the state of Roraima. The strategy adopted for the production of data was the dramatic game and the findings analyzed by the content of the speeches. A table and a word cloud were produced containing the reflections and expressions on the inducing terms “care management” and “nurse”. Among the reflections related to care management are care-management inseparability, territorial planning, situational strategic planning, systematization of nursing care, leadership, human resources, material, physical, financial resources and conflict negotiation and administrative theories themselves. Regarding the nursing subject, the need for Nightingale's theoretical anchoring was highlighted to support nursing care in an evidence-based perspective. Finally, among the problems related to the role of nurses in the Unified Health System, the following were at the center of the discussion: humanistic vision, biomedical model, biopsychosocial model and education.

IS THE ENVIRONMENT A FACTOR IN THE TRANSFORMATION OF THE COLLECTIVE INTEREST IN LABOUR LAW?
Authors: Germain Juliette
Published: February 2024

Act no. 2021-1104 of 22 August 2021, known as the “Climate and Resilience” Act, has made the environment a new subject for social dialogue, which may take the form of negotiations at branch or company level, or as part of consultations by the Social and Economic Committee. The social partners, employee representatives and the employer are involved in building a collective interest that extends to new issues, raising the question of the functions of the company. The recent introduction into European law of the due diligence is a case in point. As companies are (perhaps) no longer limited to the pursuit of profit, they could act to protect the environment, or at the very least, not contribute to its destruction or to global warming.
THE COLLECTIVE TERRITORIAL INTEREST, A NEW PARADIGM FOR TERRITORIAL PUBLIC ACTION?
Authors: Larrandaburu Iban
Published: February 2024

The segmentation of the public interest through the specialisation of the powers of local authorities has made public action more complex. The concept of collective territorial interest could be an interesting way of collectively reorganising the ways in which public institutions act. The territorial collective interest is based on the idea of a new conception of the territory, seen as dynamic and evolving. It is based on cooperation between all the public and private players in the area. It is organised around open, collaborative governance and is formally embodied in a regional project co-constructed with civil society. More than just the sum of local public interests, it would give new meaning to the actions of local authorities and improve their effectiveness in meeting the needs of local residents and stakeholders
CULTURE, LANGUAGE AND BUILDING A SOCIETY
Authors: Mickus Francis
Published: February 2024

A culture is by definition a network of shared references that give shape and meaning to a given social group. Without a culture, a group as such does not exist. This definition may seem easy to grasp, but its application is more complex than one would expect. For at the heart of cultural inclusion is language itself. The inclusiveness of language is a central concern in Shakespeare’s King Henry V. With the growth of modern print culture access to cultural inclusion was linked to the access to a print language. In France, cultural inclusion was established at the expense of internal regional, cultural and linguistic distinctiveness. Today, social tensions can be felt as a result of this historic practice, with regionalist demands that refuse to consider one’s local culture as merely aspect of one’s private convictions. Culture, more than any political or economic policy is what builds a society, but at wat price do we achieve social cohesion?
