Inversion of a SIR-based model: a critical analysis about the application to COVID-19 epidemic
Mauro Giudici, Alessandro Comunian, Romina Gaburro
Calibration of a SIR (Susceptibles-Infected-Recovered) model with official international data for the COVID-19 pandemics provides a good example of the difficulties inherent the so…
Lipschitz stability at the boundary for time-harmonic diffuse optical tomography
Olga Doeva, Romina Gaburro, William R. B. Lionheart +1
We study the inverse problem in Optical Tomography of determining the optical properties of a medium , with , under the so-called diffusion approxima…
Full Reciprocity-Gap Waveform Inversion in the frequency domain, enabling sparse-source acquisition
Florian Faucher, Giovanni Alessandrini, Hélène Barucq +3
The quantitative reconstruction of sub-surface Earth properties from the propagation of waves follows an iterative minimization of a misfit functional. In marine seismic exploratio…
EIT in a layered anisotropic medium
Giovanni Alessandrini, Maarten V. de Hoop, Romina Gaburro +1
We consider the inverse problem in geophysics of imaging the subsurface of the Earth in cases where a region below the surface is known to be formed by strata of different material…
Lipschitz stability for a piecewise linear Schrödinger potential from local Cauchy data
Giovanni Alessandrini, Maarten V. de Hoop, Romina Gaburro +1
We consider the inverse boundary value problem of determining the potential in the equation in , from local Cauchy data. A result of global…
