Conjugate gradient for ill-posed problems: regularization by preconditioning, preconditioning by regularization
Ahmed Chabib, Jean-Francois Witz, Vincent Magnier +1
This paper investigates using the conjugate gradient iterative solver for ill-posed problems. We show that preconditioner and Tikhonov-regularization work in conjunction. In partic…

Multi-scale friction coefficient: From roughness to system computation using deep learning
Victor Lalleman, Pierre Gosselet, Cédric Hubert +2
The presence of surface defects (roughness, surface imperfections, profiles, etc.) in a contact inevitably leads to the modification of its local properties, such as the coefficien…
