New inversion methods for the single/multi-shape CLD-to-PSD problem with spheroid particles
Lucas Brivadis, Ludovic Sacchelli
In this paper, we express the Chord Length Distribution (CLD) measure associated to a given Particle Size Distribution (PSD) when particles are modeled as suspended spheroids in a…
Uniform, localized asymptotics for sub-Riemannian heat kernels, their logarithmic derivatives, and associated diffusion bridges
Robert W. Neel, Ludovic Sacchelli
We show that the small-time asymptotics of the sub-Riemannian heat kernel, its derivatives, and its logarithmic derivatives can be localized, allowing them to be studied even on in…
New perspectives on output feedback stabilization at an unobservable target
Lucas Brivadis, Jean-Paul Gauthier, Ludovic Sacchelli +1
We address the problem of dynamic output feedback stabilization at an unobservable target point. The challenge lies in according the antagonistic nature of the objective and the pr…
From local to global asymptotic stabilizability for weakly contractive control systems
Vincent Andrieu, Lucas Brivadis, Jean-Paul Gauthier +2
A nonlinear control system is said to be weakly contractive in the control if the flow that it generates is non-expanding (in the sense that the distance between two trajectories i…
A bio-inspired geometric model for sound reconstruction
Ugo Boscain, Dario Prandi, Ludovic Sacchelli +1
The reconstruction mechanisms built by the human auditory system during sound reconstruction are still a matter of debate. The purpose of this study is to propose a mathematical mo…
