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…
Robust Control Invariance and Communication Scheduling in Lossy Wireless Networked Control Systems
Masoud Bahraini, Mario Zanon, Paolo Falcone +1
In Networked Control Systems (NCS) impairments of the communication channel can be disruptive to stability and performance. In this paper, we consider the problem of scheduling the…
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…
Robust Supervisors for Intersection Collision Avoidance in the Presence of Uncontrolled Vehicles
Heejin Ahn, Andrea Rizzi, Alessandro Colombo +1
We present the design and validation of a centralized controller, called a supervisor, for collision avoidance of multiple human-driven vehicles at a road intersection, considering…
Discontinuity induced bifurcations of non-hyperbolic cycles in nonsmooth systems
Alessandro Colombo, Fabio Dercole
We analyse three codimension-two bifurcations occurring in nonsmooth systems, when a non-hyperbolic cycle (fold, flip, and Neimark-Sacker cases, both in continuous- and discrete-ti…
