The dynamical collision network in granular gases
(American Physical Society, 2007-05)
We address the problem of recollisions in cooling granular gases. To this aim, we dynamically construct the interaction network in a granular gas, using the sequence of collisions collected in an event driven simulation ...
Comparisons between singularities of pseudophase and speckle phase using binary diffusers in optical vortex metrology
(Society of Photo-Optical Instrumentation Engineers, 2016-12)
An analysis based on the comparison between singularities of speckle phase and pseudophase in the practice of optical vortex metrology is carried out by measuring the phase map of the speckle pattern obtained from the ...
Dust trapping around Lagrangian points in protoplanetary disks
(EDP Sciences, 2020-10)
Trojans are defined as objects that share the orbit of a planet at the stable Lagrangian points L4 and L5. In the Solar System, these bodies show a broad size distribution ranging from micrometer (μm) to centimeter (cm) ...
Anomalies in vortex lattice dynamics driven by induced ac currents in superconducting films with magnetic arrays of two-fold symmetry
(IOP Publishing, 2015-02)
We study the dynamics of the vortex lattice driven by ac induced currents in the critical state regime, for T>0.70 T C . The samples are superconducting films grown on top of two-fold symmetry array of magnetic dots. In ...
Range overlap between the sword-billed hummingbird and its guild of long-flowered species: An approach to the study of a coevolutionary mosaic
(Public Library of Science, 2018-12)
The coevolutionary process among free-living mutualists with extremely long matching traits may favor the formation of mutualistic interaction networks through coevolutionary escalation, complementarity and convergence. ...
Diseño de sistemas de amortiguamiento para líneas eléctricas usando diferentes enfoques
(Universidad Nacional de Córdoba. Facultad de Ciencias Exactas, Físicas y Naturales, 2018-09)
Las vibraciones inducidas por el viento, asociadas al fenómeno de desprendimiento de vórtices, tienen un fuerte impacto en la vida útil de conductores eléctricos en líneas de alta tensión debido a la ocurrencia de ...
Two-dimensional numerical simulations of detonation cellular structures in H2–O2–Ar mixtures with OpenFOAM®
(Pergamon-Elsevier Science Ltd, 2017-09)
In the present work, the solver rhoCentralRfFoam, developed using the finite volume framework provided by OpenFOAM®, is employed to perform numerical simulations of two-dimensional detonations. This solver uses the central ...
The wake asymmetry of an airfoil with a Gurney flap and their connection with the observed lift increase
(Praise Worthy Prize, 2010-04)
The present research analyzes the asymmetry in the rolling up shear layers downstream the blunt trailing edge of airfoils with Gurney flaps as a lift enhancing mechanism. Experimental investigations relating the asymmetry ...
From the nonlinear Fokker-Planck equation to the Vlasov description and back: Confined interacting particles with drag
(American Physical Society, 2018-02)
Nonlinear Fokker-Planck equations endowed with power-law diffusion terms have proven to be valuable tools for the study of diverse complex systems in physics, biology, and other fields. The nonlinearity appearing in these ...
Medicanes as subtropical cyclones: the December 2005 case from the perspective of surface pressure tendency diagnostics and atmospheric water budget
(John Wiley & Sons Ltd, 2018-04)
Mediterranean cyclones with tropical-like characteristics such as spiral cloud coverage and a central cloud-free “eye” are referred to as medicanes. These systems have been analyzed due to their relation with high-impact ...
