Modeling and optimization of a tangential photocatalytic reactor for uniform distribution of pollutant-laden air on the reactive area

I. Abattouy, A. Meslem, M. Mahdaoui, M. Ahachad, C. Guillard, F. Dappozze, T. Randrianasolo, L. Peruchon, C. Brochier, L. Lamaa

Photocatalysis has shown significant promise due to its ability to chemically degrade volatile organic compounds (VOCs) using TiO₂ and UV irradiation. However, the efficiency of chemical degradation in photocatalytic reactors is often limited by a poor distribution of airflow in the vicinity of the...

Impact of local forging parameters on the microstructural evolution and mechanical properties of hot forging steel dies

José Gregorio La Barbera-Sosa, Nasrine Boualem, Mirentxu Dubar, Rudy Dubois, Philippe Moreau, Tarik Sadat, Laurent Dubar, Philippe Bristiel

An original multi-scale approach is proposed to understand how local forging parameters influence the evolution of the topography, microstructure and mechanical properties near the tool surface during its service life. To this end, the study is based on observing the geometric elements constituting...

An Octree-based adaptive moving thermal-fluid framework for efficient multi-scale and multi-physics simulation of laser-based manufacturing processes

Yabo Jia, Alain Rassineux, Jean-Michel Bergheau

Multiphysics and multi-scale thermal-fluid models are essential for understanding the coupling of physical phenomena, enabling the optimization of welding and additive manufacturing process parameters. However, the thermal-fluid simulations are extremely time-consuming due to the need for a fine...

How is remifentanil dosed without dedicated indicator?

Bob Aubouin--Pairault, Mazen Alamir, Benjamin Meyer, Rémi Wolf, Kaouther Moussa

This study investigates the paradigm of intraoperative analgesic dosage using a data-driven approach based on retrospective clinical data. Remifentanil, an analgesic widely used during anesthesia, presents a dosing challenge due to the absence of an universally accepted indicator of analgesia. To...

Conception, réalisation et évaluation d’une assistance à la conduite automobile intégrant des capacités d’auto-apprentissage des préférences du conducteur, Design, implementation and evaluation of a driver assistance system integrating self-learning capabilities based on driver preferences

Yikai Wang

Les systèmes avancés d’assistance à la conduite (ADAS) ont connu un développement considérable au cours de ces dernières années. Cependant, les ADAS permettant la conduite en mode autonome sont fondés habituellement sur des règles fixes, ce qui limite d’une part leur capacité à s’adapter aux..., Advanced Driver Assistance Systems (ADAS) have undergone considerable development in recent years. However, ADAS that enable autonomous driving are generally based on fixed rules, which on one hand limits their ability to adapt to differences in driver behavior, and on the other hand prevents them...
