Sparse-grids-like surrogate models enhanced with gradient information
Andrea Bressan, Sofia Imperatore, Francesca Locatelli +1
This work concerns surrogate modeling for quantities of interest (QoI) arising from parametric non-linear partial differential equations (PDEs). More specifically, we consider exte…
Towards uncertainty quantification of a model for cancer-on-chip experiments
Silvia Bertoluzza, Vittoria Bianchi, Gabriella Bretti +2
This study is a first step towards using data-informed differential models to predict and control the dynamics of cancer-on-chip experiments. We consider a conceptualized one-dimen…
An efficient slope stability algorithm with physically consistent parametrisation of slip surfaces
Leonardo Maria Lalicata, Andrea Bressan, Simone Pittaluga +2
This paper presents an optimised algorithm implementing the method of slices for analysing the stability of slopes. The algorithm adopts an improved physically based parameterisati…
Two Nitsche-based mixed finite element discretizations for the seepage problem in Richards' equation
Federico Gatti, Andrea Bressan, Alessio Fumagalli +4
This paper proposes two algorithms to impose seepage boundary conditions in the context of Richards' equation for groundwater flows in unsaturated media. Seepage conditions are non…
