Preconditioning across parameter space for the parametric Helmholtz equation
Wouter Gerrit van Harten, Laura Scarabosio
In this work, we address the efficient computation of parameterized systems of linear equations, with possible nonlinear parameter dependence. When the matrix is highly sensitive t…

Wavenumber-Explicit Well-Posedness of Bayesian Shape Inversion in Acoustic Scattering
Safiere Kuijpers, Laura Scarabosio
We consider the Bayesian approach to the inverse problem of recovering the shape of an object from measurements of its scattered acoustic field. Working in the time-harmonic settin…

Application of the thin-film equations in modelling of Marangoni flow patterns amongst surfactant source and drain locations
Julio Careaga, Peter A. Korevaar, Vanja NikoliÄ +1
Surfactants that are deposited at aqueous liquid films have the ability to generate surface tension gradients at the air-water interface, and thereby induce Marangoni flow. Combine…
