Quantitative analysis of finite-difference approximations of free-discontinuity problems [PDF]

open access: yesInterfaces and free boundaries (Print), 2018
Motivated by applications to image reconstruction, in this paper we analyse a \emph{finite-difference discretisation} of the Ambrosio-Tortorelli functional.

On a discrete-to-continuum convergence result for a two dimensional brittle material in the small displacement regime

open access: yesNetworks and Heterogeneous Media, 2015
We consider a two-dimensional atomic mass spring system and show that in the small displacement regime the corresponding discrete energies can be related to a continuum Griffith energy functional in the sense of $\Gamma$-convergence.

Reconstruction of cracks and material losses by perimeter-like penalizations and phase-field methods: numerical results [PDF]

open access: yes, 2010
We numerically implement the variational approach for reconstruction in the inverse crack and cavity problems developed by one of the authors. The method is based on a suitably adapted free-discontinuity problem.

Different views about work-hour limitations in medicine: a qualitative content analysis of surgeons', lawyers', and pilots' positive and negative arguments. [PDF]

open access: yesPLoS ONE, 2014
Whereas work-hour regulations have been taken for granted since 1940 in other occupational settings, such as commercial aviation, they have been implemented only recently in medical professions, where they lead to a lively debate.
