The Scatman: an approximate method for fast wide-angle scattering simulations
Alessandro Colombo, Julian Zimmermann, Bruno Langbehn +8
Single-shot Coherent Diffraction Imaging (CDI) is a powerful approach to characterize the structure and dynamics of isolated nanoscale objects such as single viruses, aerosols, nan…
p-Multigrid matrix-free discontinuous Galerkin solution strategies for the under-resolved simulation of incompressible turbulent flows
Matteo Franciolini, Lorenzo Botti, Alessandro Colombo +1
In recent years several research efforts focused on the development of high-order discontinuous Galerkin (dG) methods for scale resolving simulations of turbulent flows. Neverthele…
h-multigrid agglomeration based solution strategies for discontinuous Galerkin discretizations of incompressible flow problems
Lorenzo Botti, Alessandro Colombo, Francesco Bassi
In this work we exploit agglomeration based -multigrid preconditioners to speed-up the iterative solution of discontinuous Galerkin discretizations of the Stokes and Navier-Stok…
Facing the phase problem in Coherent Diffractive Imaging via Memetic Algorithms
Alessandro Colombo, Davide Emilio Galli, Liberato De Caro +2
Coherent Diffractive Imaging is a lensless technique that allows imaging of matter at a spatial resolution not limited by lens aberrations. This technique exploits the measured dif…
