The Wolf and the Cello: Modelling and design of multiple resonance suppressors in large string instruments
Simone Cacace, Emiliano Cristiani, Francesca L. Ignoto
The wolf note is an acoustic instability that occurs in large bowed string instruments when a strong body resonance interacts with the vibrating string, producing amplitude modulat…
Numerical Hopf-Lax formulae for Hamilton-Jacobi equations on unstructured geometries
Simone Cacace, Roberto Ferretti, Giulia Tatafiore
We consider a scheme of Semi-Lagrangian (SL) type for the numerical solution of Hamilton-Jacobi (HJ) equation on unstructured triangular grids. As it is well known, SL schemes are…
A macroscopic pedestrian model with variable maximal density
Laura Bartoli, Simone Cacace, Emiliano Cristiani +1
In this paper we propose a novel macroscopic (fluid dynamics) model for describing pedestrian flow in low and high density regimes. The model is characterized by the fact that the…
Reliable optimal controls for SEIR models in epidemiology
Simone Cacace, Alessio Oliviero
We present and compare two different optimal control approaches applied to SEIR models in epidemiology, which allow us to obtain some policies for controlling the spread of an epid…
