The RBF Collocation Method to Design a Digital Twin for Coffee Percolation
Nadaniela Egidi, Lauro Fioretti, Josephin Giacomini +2
Espresso coffee extraction is a complex physico-chemical process and can be modeled through a system of coupled partial differential equations. We present a numerical solution base…
Inverse modeling of porous flow through deep neural networks: the case of coffee percolation
Antoniorenee Barletta, Salvatore Cuomo, Nadaniela Egidi +2
This work addresses the inverse problem of espresso coffee extraction, in which one aims to reconstruct the brewing conditions that generate a desired chemical profile in the final…
Computational issues by interpolating with inverse multiquadrics: a solution
Stefano De Marchi, Nadaniela Egidi, Josephin Giacomini +2
We consider the interpolation problem with the inverse multiquadric radial basis function. The problem usually produces a large dense linear system that has to be solved by iterati…
