From equilibrium statistical physics under experimental constraints to macroscopic port-Hamiltonian systems

Autor: Judy Najnudel, Thomas Hélie, David Roze, Rémy Müller

This paper proposes to build a bridge between microscopic descriptions of matter with internal energy, composed of many fast interacting particles inside an environment, and their port-Hamiltonian (PH) descriptions at macroscopic scale. The environme

Introduction: There is increasing recognition that first responders’ exposure to multiple traumatic events puts them at risk for the development of emotional distress, including depression, substance misuse, posttraumatic stress disorder (PTSD), an

International audience; The framework of nonlinear normal modes gives a remarkable insight into the dynamics of nonlin-ear vibratory systemsexhibiting distributed nonlinearities. In the case of Chinese opera gongs, geo-metrical nonlinearities lead to
