Modélisation biomécanique tri-dimensionnelle de l'articulateur lingual pour étudier le contrôle de la parole
Jean-Michel Gerard, Pascal Perrier, Yohan Payan
A 3D biomechanical dynamical model of human tongue is presented, which is elaborated to test in the future hypotheses about speech motor control. Tissue elastic properties are acco…
Reproduction of hypopnea phenomenon using a physical and numerical model
Franz Chouly, Annemie Van Hirtum, Pierre-Yves Lagrée +2
Obstructive sleep apnea syndrome is now considered as a major health care topic. An in-vitro setup which reproduces and simplifies upper airway geometry has been the basis to study…
Modéliser le physique pour comprendre le contrôle : le cas de l'anticipation en production de parole
Pascal Perrier, Yohan Payan, Romain Marret
This chapter introduces numerical simulations provided by a 2D biomechanical model of the tongue. These simulations help in understanding the influence of the lingual mechanical ch…
Statistical skull models from 3D X-ray images
Maxime Berar, Michel Desvignes, Gérard Bailly +1
We present 2 statistical models of the skull and mandible built upon an elastic registration method of 3D meshes. The aim of this work is to relate degrees of freedom of skull anat…
Physical modelling of the airflow-walls interactions to understand the sleep apnea syndrome
Yohan Payan, Xavier Pelorson, Pascal Perrier
Sleep Apnea Syndrome (SAS) is defined as a partial or total closure of the patient upper airways during sleep. The term "collapsus" (or collapse) is used to describe this closure.…
A 3D dynamical biomechanical tongue model to study speech motor control
Jean-Michel Gerard, Reiner Wilhelms-Tricarico, Pascal Perrier +1
A 3D biomechanical dynamical model of human tongue is presented, that is elaborated in the aim to test hypotheses about speech motor control. Tissue elastic properties are accounte…
