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…

Implementation of a dual heterogeneity test in stress and temperature for the inverse identification of material constitutive laws, Essai à double hétérogénéité mécanique et thermique pour l'identification de lois de comportement de matériaux par méthode inverse

Quentin Marcot

This thesis work aims at implementing a test presenting two heterogeneities in stress and temperature for material characterisation. In the aerospace industry, certification programs are increasingly relying on model and simulation to reduce the number of physical tests performed upon structures.…, Ces travaux de thèse ont pour objectif d'implémenter un essai présentant une double hétérogénéité mécanique et thermique, en vue de l'identification de lois de comportement de matériaux par méthode inverse. Dans l'industrie aérospatiale, les programmes de certification s'…

MPC for tracking for anesthesia dynamics

Maxim Raymond, Kaouther Moussa, Mirko Fiacchini, Jimmy Lauber

<div><p>In this paper, an MPC for tracking formulation is proposed for the control of anesthesia dynamics. It seamlessly enables the optimization of the steady-states pair that is not unique due to the MISO nature of the model. Anesthesia dynamics is a multi-time scale system with two…

Vers une transformation numérique des PME industrielles par le TALN, les grands modèles de langage et le RAG : une contribution méthodologique, Toward a Digital Transformation of Industrial SMEs through NLP, Large Language Models, and RAG : A Methodological Contribution

Mathieu Bourdin

Cette thèse explore l’intégration du Traitement Automatique du Langage Naturel (TALN) et des Grands Modèles de Langage (LLM) dans les Petites et Moyennes Entreprises (PME) industrielles, dans le cadre de l’Industrie 4.0. Bien que cruciales pour l’économie mondiale, ces entreprises rencontrent des…, This thesis explores the integration of Natural Language Processing (NLP) and Large Language Models (LLMs) in industrial Small and Medium-Sized Enterprises (SMEs) within the framework of Industry 4.0. Although essential to the global economy, these companies face limitations related to resources,…

Covariance Control for a class of Stochastic Discrete-time Linear Systems using the S-Variable Approach

Kaouther Moussa, Dimitri Peaucelle

This paper deals with the problem of covariance control for a class of linear stochastic discrete-time systems in the Stochastic Model Predictive Control (SMPC) framework. The considered systems are affected by independent and identically distributed (i.i.d.) additive and parametric stochastic…

Biomechanical finite element simulation of the pelvic organs under dynamic loading and validation against experimental data from magnetic resonance imaging

Camille Lafond, Louise Hohnadel, Thomas Brunel, Nicolas Pirrò, Marc-Emmanuel Bellemare, Dominique Chamoret, Sébastien Roth

Pelvic organ prolapse (POP) is a prevalent condition affecting women, particularly those over the age of 50. The etiology and pathophysiology of this condition remain poorly understood within the medical community. In recent years, researchers, particularly medical engineers and biomechanical…
