Modeling nonlocal behavior in epidemics via a reaction-diffusion system incorporating population movement along a network

no code implementations9 May 2022 Malú Grave, Alex Viguerie, Gabriel F. Barros, Alessandro Reali, Roberto F. S. Andrade, Alvaro L. G. A. Coutinho

Recent works have focused on partial differential equation (PDE) models, particularly reaction-diffusion models, able to describe the progression of an epidemic in both space and time.

Coupled and Uncoupled Dynamic Mode Decomposition in Multi-Compartmental Systems with Applications to Epidemiological and Additive Manufacturing Problems

no code implementations12 Oct 2021 Alex Viguerie, Gabriel F. Barros, Malú Grave, Alessandro Reali, Alvaro L. G. A. Coutinho

In these cases, the behavior of the system may not be accurately recreated by applying DMD to a single quantity within the system, as proper knowledge of the system dynamics, even for a single compartment, requires that the behavior of other compartments is taken into account in the DMD process.

Dynamic Mode Decomposition in Adaptive Mesh Refinement and Coarsening Simulations

no code implementations28 Apr 2021 Gabriel F. Barros, Malú Grave, Alex Viguerie, Alessandro Reali, Alvaro L. G. A. Coutinho

The present strategy is applied to challenging AMR/C simulations: a continuous diffusion-reaction epidemiological model for COVID-19, a density-driven gravity current simulation, and a bubble rising problem.

Assessing the spatio-temporal spread of COVID-19 via compartmental models with diffusion in Italy, USA, and Brazil

no code implementations14 Feb 2021 Malú Grave, Alex Viguerie, Gabriel F. Barros, Alessandro Reali, Alvaro L. G. A. Coutinho

Such models are usually defined as compartmental models, in which the population under study is divided into compartments based on qualitative characteristics, with different assumptions about the nature and rate of transfer across compartments.

Image-based numerical characterization and experimental validation of tensile behavior of octet-truss lattice structures

no code implementations14 Dec 2020 Nina Korshunova, Gianluca Alaimo, Seyyed Bahram Hosseini, Massimo Carraturo, Alessandro Reali, Jarkko Niiranen, Ferdinando Auricchio, Ernst Rank, Stefan Kollmannsberger

The production of lightweight metal lattice structures has received much attention due to the recent developments in additive manufacturing (AM).

Reduced Order Isogeometric Analysis Approach for PDEs in Parametrized Domains

no code implementations21 Nov 2018 Fabrizio Garotta, Nicola Demo, Marco Tezzele, Massimo Carraturo, Alessandro Reali, Gianluigi Rozza

In this contribution, we coupled the isogeometric analysis to a reduced order modelling technique in order to provide a computationally efficient solution in parametric domains.
