Etude de cas : L’optimisation d’une unité industrielle d’osmose inverse (OI) via l’intégration d’un jumeau numérique (JN) et de la réalité augmentée (RA).
L’osmose inverse (OI) est un procédé essentiel pour la production d’eau ultrapure dans divers secteurs industriels, mais son optimisation se heurte à des défis significatifs : complexité des paramètres physico-chimiques, maintenance prédictive des membranes, exigences de traçabilité et risques d’erreurs humaines [1-5]. L’émergence des technologies de l’Industrie 4.0, notamment le jumeau numérique (JN) [6, 8] […]

Role tension and perceived leadership influence on middle managers’ transformational leadership
Objectives & Literature Middle managers in the nuclear sector, as in other organizations, are key players in implementing policies and strategy. They are frequently exposed to paradoxical leadership styles and demands (Berti et Simpson, 2021). It gives rise to role tensions (i.e., role conflict, organizational cynicism, or cognitive dissonance) for middle managers (Razouk et Quéméner, […]

Advanced Multi-Model Prediction of Aircraft Engine Remaining Useful Life with Random Sampling-Based Class Balancing and Voting-Based Features Selection
In Industry 4.0, predictive maintenance for critical systems like aircraft engines relies on accurate Remaining Useful Life (RUL) estimation to prevent unexpected failures and optimize maintenance schedules. However, existing models face several limitations that hinder their effectiveness in real-world applications. Common challenges include data imbalance, which can lead to biased predictions; suboptimal feature selection, which […]

Is fiscal countercyclicality growth enhancing? Evidence from developing countries over the period 1990–2019
The objective of this paper is to analyze the time-varying effect of improving fiscal countercyclicality on growth for a sample of 35 developing countries over the period 1990–2019. By estimating a time-varying coefficient for fiscal countercyclicality, incorporated as a variable in a panel model, we first examine how the public debt ratio and electoral motivations […]

The Augmented Perception: an emerging approach toward resilient manufacturing systems involving robotic agents and digital twin.
This paper addresses the resilience of Industry 5.0 Manufacturing Systems (MS) with mobile robotic agents, focusing on robustness (handling disruptions while maintaining production) and flexibility (adapting to reconfigurations). We propose Augmented Perception (AP), a Digital Twin-based approach that enhances robot perception by integrating virtual elements in the map of the robot. Three use cases, in […]

Extensive development of a Bayesian calibration approach for building energy models using an innovative case study: a shipping container building.
The building sector is responsible for almost a third of global energy consumption and a quarter of CO2 emissions. Innovative architectural designs that promote the reusability of raw materials, such as shipping container architecture, can help to reduce construction’s environmental impact. By creating physical models to analyze energy consumption, we can develop practical tools to […]
