The fine geometry of the Cantor families of invariant tori in hamiltonian systems
(2000)
Article
Accés obertThis work focuses on the dynamics around a partially elliptic, lower dimensional torus of a real analytic Hamiltonian system. More concretely, we investigate the abundance of invariant tori in the directions of the phase ... -
Theory and computation of multiscale epithelial mechanics : from active gels to vertex models
(Universitat Politècnica de Catalunya, 2023-06-14)
Tesi
Accés obert(English) Epithelial monolayers perform a variety of mechanical functions, which include maintaining a cohesive barrier or developing 3D shapes, while undergoing stretches over a wide range of magnitudes and loading rates. ... -
Three-dimensional quasiperiodic torsional flows in rotating spherical fluids at very low Prandtl numbers
(2021-11-04)
Article
Accés obertThe aim of this study is to determine through numerical simulations the extent and robustness of the three-dimensional torsional dynamics of the thermal convection in rotating spherical fluids at very low Prandtl numbers. ... -
Transition to periodic behaviour of flow past a circular cylinder under the action of fluidic actuation in the transitional regime
(2021-08)
Article
Accés obertThis study focuses on the numerical investigation of the underlying mechanism of transition from chaotic to periodic dynamics of circular cylinder wake under the action of time-dependent fluidic actuation at the Reynolds ... -
Transitions between symmetric and nonsymmetric regimes in binary-mixture convection
(Elsevier, 2015-05-15)
Article
Accés obertWe present here a comprehensive picture of the different bifurcations found for small to moderate Rayleigh number in binary-mixture convection with lateral heating and negative separation ratio (S). The present work connects ... -
Turing universality of the incompressible Euler equations and a conjecture of Moore
(2021-04-09)
Report de recerca
Accés obertIn this article we construct a compact Riemannian manifold of high dimension on which the time dependent Euler equations are Turing complete. More precisely, the halting of any Turing machine with a given input is equivalent ... -
Two computational approaches for the simulation of fluid problems in rotating spherical shells
(2014)
Comunicació de congrés
Accés obertMany geophysical and astrophysical phenomena such as magnetic fields generation, or the differential rotation observed in the atmospheres of the major planets are studied by means of numerical simulations of the Navier-Stokes ... -

Unifying Deterministic and Stochastic Models in Drylands
(Universitat Politècnica de Catalunya, 2021-05)
Projecte Final de Màster Oficial
Accés obertUnderstanding the causes and effects of spatial vegetation patterns in semi-arid ecosystems is a fundamental problem in ecology, especially because these can be used as early predictors for catastrophic shifts such as ... -
Viral replication modes in single-peak fitness landscapes: A dynamical systems analysis
(2019-01-07)
Article
Accés obertPositiv e-sense, single-stranded RN A viruses are im portant pathogens infecting almost all types of organ- isms. Experimental evidence from distributions of mutations and from viral RN A ampli¿cation suggest that these ... -
Warmer temperatures and their effect on East-African malaria
(Universitat Politècnica de Catalunya, 2020-07)
Projecte Final de Màster Oficial
Accés obertMalaria has been an issue worldwide for a long time, having a huge social, economic, and health burden. This disease occurs mostly in tropical and subtropical areas of the world, in countries where the levels of poverty ...
