Visibility Interpolation in Solar Hard X-ray Imaging: Application to RHESSI and STIX
Emma Perracchione, Paolo Massa, Anna Maria Massone +1
Space telescopes for solar hard X-ray imaging provide observations made of sampled Fourier components of the incoming photon flux. The aim of this study is to design an image recon…
Data-driven extrapolation via feature augmentation based on variably scaled thin plate splines
Rosanna Campagna, Emma Perracchione
The data driven extrapolation requires the definition of a functional model depending on the available data and has the application scope of providing reliable predictions on the u…
A greedy non-intrusive reduced order model for shallow water equations
Sourav Dutta, Matthew W. Farthing, Emma Perracchione +2
In this work, we develop Non-Intrusive Reduced Order Models (NIROMs) that combine Proper Orthogonal Decomposition (POD) with a Radial Basis Function (RBF) interpolation method to c…
