Deformable bodies in a 3-dimensional viscous flow: Vorticity-Stream vector formulation
Andreu F. Gallen, Joan Muñoz Biosca, Mario Castro +1
When simulating three-dimensional flows interacting with deformable and elastic obstacles, current methods often encounter complexities in the governing equations and challenges in…
Linear quadratic control of nonlinear systems with Koopman operator learning and the Nyström method
Edoardo Caldarelli, Antoine Chatalic, Adrià Colomé +4
In this paper, we study how the Koopman operator framework can be combined with kernel methods to effectively control nonlinear dynamical systems. While kernel methods have typical…
Modelling mass transfer from a packed bed by fluid extraction
Timothy G. Myers, Abel Valverde, Maria Aguareles +2
A mathematical model describing the erosion or leaching of a solid material by a flowing fluid in a column is developed. This involves an advection-diffusion equation coupled to a…
Renormalizing the vacuum energy in cosmological spacetime: implications for the cosmological constant problem
Cristian Moreno-Pulido, Joan Sola Peracaula
The renormalization of the vacuum energy in quantum field theory (QFT) is usually plagued with theoretical conundrums related not only with the renormalization procedure itself, bu…
Heaps' Law and Vocabulary Richness in the History of Classical Music Harmony
Marc Serra-Peralta, Joan Serrà, Álvaro Corral
Music is a fundamental human construct, and harmony provides the building blocks of musical language. Using the Kunstderfuge corpus of classical music, we analyze the historical ev…
On cosmological expansion and local physics
J. M. Pons, P. Talavera
We find an exact convergence in the local dynamics described by two supposedly antagonistic approaches in modern cosmology: one starting from an expanding universe perspective such…
