Classification des mécanismes d'usure lors du formage d'aluminium à haute température par apprentissage automatique et profond

Philippe Moreau, Panuwat Soranansri, Lucas Morin, Donatien Claeyssens-Beaupere, Franck Massa, Fabien Béchet, Ahmed Snoun, Thierry Delot, Laurent Dubar, André Dubois

La fabrication écoresponsable privilégie le formage sans lubrifiant afin de réduire les coûts et minimiser l'impact environnemental. Dans le cas du formage à haute température des alliages d'aluminium, cette approche qui se traduit par un contact direct entre la pièce et les outils,…, Green manufacturing focuses lubricant-free forming in order to reduce costs and minimise environmental impact. In the case of high-temperature forming of aluminium alloys, this approach, which results in direct contact between the part and the tools, leads to material transfer and surface defects.…

Set up son? Scam set, asserts Bob": Semi-Automatic Generation of Bilingual Palindromes

August Adams, Enka Blanchard, Inès Dardouri, Levi Gabasova, Pierre Midavaine

We analyse the problem of composing bilingual palindromes, for which the only high-quality example known is more than 150 years old. We formalise the problem and introduce multiple partial solutions for computer-assisted palindrome composition, as well as a comparison between the composition…

Comprehensive database for benchmarking markerless motion capture methodologies: example results

Antoine Muller, Raphaël Dumas, Alexandre Naaïm, Mohamed Adjel, Sandrine Bousigues, Anaïs Chaumeil, Marien Couvertier, David Pagnon, Diana Pardo Ramos, Alexandre Schortgen, Thomas Robert

A comprehensive database is introduced including markerless, marker-based, and biomechanical estimations derived from various markerless processing methods. This database can be useful for benchmarking markerless method to estimated biomechanical variables. As an example, this abstract provides a…

Impact of video resolution on center of mass estimation: A cross-models analysis (preliminary study)

Ahmed Yacine Lardjane, David Pagnon, Laura Wallard, Christophe Gillet, Christopher Paglia, Sébastien Leteneur, Emilie Simoneau-Buessinger, Mathias Blandeau

<div><p>Recent advances in markerless motion capture (MC) have made biomechanical analysis more accessible. However, video parameters might affect pose estimation accuracy. This study investigates how video quality (540p and 1080p at 16:9) influences 3D center of mass (CoM) accuracy…

Stability Analysis of Variable Impedance Control for Rehabilitation Exoskeletons: quasi-LPV models and LMI conditions

Maxime Thieffry, Antoine Dequidt, Laurent Vermeiren, Philippe Pudlo

Exoskeletons are set to play an important role in the future of rehabilitation processes, and safe interactions are therefore seen as a fundamental prerequisite. This article contributes by presenting a novel assistance modulation strategy to best meet the patients needs as well as a dedicated…

An experimental investigation of the effect of high intensity turbulence on a slenderbody wake., Étude expérimentale de l’effet de la turbulence à haute intensité sur le sillage d’un corps allongé.

Chandra Sekhar Kommineni

The resurgence of slow-flying aircraft operating in disturbed environments requires taking into account realistic unsteady conditions (turbulence, variability of loads…) and their coupling with the intrinsic wake dynamics. We propose to study the near wake of a slender ellipsoidal body, which…, La résurgence des aéronefs lents, opérant dans un environnement perturbé, nécessite la prise en compte de conditions réalistes instationnaires (turbulences, variabilité des contraintes…) et de leurs couplages avec les dynamiques intrinsèques de sillages.
