Notes on numerical analysis and solitary wave solutions of Boussinesq/Boussinesq systems for internal waves
V. A. Dougalis, A. Duran, L. Saridaki
In this paper a three-parameter family of Boussinesq systems is studied. The systems have been proposed as models of the propagation of long internal waves along the interface of a…
Quantifying the structure of strong gravitational lens potentials with uncertainty-aware deep neural networks
Georgios Vernardos, Grigorios Tsagkatakis, Yannis Pantazis
Gravitational lensing is a powerful tool for constraining substructure in the mass distribution of galaxies, be it from the presence of dark matter sub-halos or due to physical mec…
Discrete Empirical Interpolation and unfitted mesh FEMs: application in PDE-constrained optimization
Georgios Katsouleas, Efthymios N. Karatzas, Fotios Travlopanos
In this work, we investigate the performance CutFEM as a high fidelity solver as well as we construct a competent and economical reduced order solver for PDE-constrained optimizati…
A Reduced Order Cut Finite Element method for geometrically parameterized steady and unsteady Navier-Stokes problems
Efthymios N. Karatzas, Monica Nonino, Francesco Ballarin +1
This work focuses on steady and unsteady Navier-Stokes equations in a reduced order modeling framework. The methodology proposed is based on a Proper Orthogonal Decomposition withi…
A regularized shallow-water waves system with slip-wall boundary conditions in a basin: Theory and numerical analysis
Samer Israwi, Henrik Kalisch, Theodoros Katsaounis +1
The simulation of long, nonlinear dispersive waves in bounded domains usually requires the use of slip-wall boundary conditions. Boussinesq systems appearing in the literature are…
Modeling the evolution of COVID-19 via compartmental and particle-based approaches: application to the Cyprus case
Constantia Alexandrou, Vangelis Harmandaris, Anastasios Irakleous +2
We present two different approaches for modeling the spread of the COVID-19 pandemic. Both approaches are based on the population classes susceptible, exposed, infectious, quaranti…
