Increased rainfall remarkably freshens estuarine and coastal waters on the Pacific coast of Panama: Magnitude and likely effects on upwelling and nutrient supply.
(Elsevier Science, 2012-07)
Increased intensity of rainfall events during late 2010 led to a remarkable freshening of estuarine, near- and off-shore waters in coastal Pacific Panama. The increased rain intensity during the wet season of 2010 lowered ...
Dynamic Monte Carlo simulation of oscillations and pattern formation during the NO+CO reaction on the Pt (100) surface
(Elsevier Science, 2006-02)
Theoretical simulations by a dynamic Monte Carlo method were carried out with respect to the catalytic reduction of NO by CO on the Pt(100) surface. This reaction, when occurring at low pressures and under certain reaction ...
Plasmon-driven sub-picosecond breathing of metal nanoparticles
(Royal Society of Chemistry, 2017-09)
We present the first real-time atomistic simulation on the quantum dynamics of icosahedral silver nanoparticles under strong laser pulses, using time dependent density functional theory (TDDFT) molecular dynamics. We ...
Admittance Controller with Spatial Modulation for Assisted Locomotion using a Smart Walker
(Springer, 2019-06)
Smart Walkers are robotic devices that may be used to improve the stability in people with lower limb weakness or poor balance. Such devices may also offer support for cognitive disabilities and for people that cannot ...
Acoustic Far-Field Hypersonic Surface Wave Detection with Single Plasmonic Nanoantennas
(American Physical Society, 2018-12)
The optical properties of small metallic particles allow us to bridge the gap between the myriad of subdiffraction local phenomena and macroscopic optical elements. The optomechanical coupling between mechanical vibrations ...
Coupled axial/torsional vibrations of drill-strings by means of non-linear model
(Pergamon-Elsevier Science Ltd, 2007-07)
In the present work a geometrically non-linear model is presented to study the coupling of axial and torsional vibrations on a drill-string, which is described as a vertical slender beam under axial rotation. It is known ...
Correlation functions in mixtures with energetically favoured nearest neighbours of different kind: A size-asymmetric case
(Taylor & Francis Ltd, 2020-09-14)
Binary mixtures of hard spheres with different diameters and square-well attraction between different particles are studied by theory and Monte Carlo simulations. In our mesoscopic theory, local fluctuations of the volume ...
Numerical stability analysis and control of umbilical-ROV systems in one-degree-of-freedom taut-slack condition
(Springer, 2007-07)
In this paper, the stability of an umbilical-ROV system under nonlinear oscillations in heave motion is analyzed using numerical methods for the uncontrolled and controlled cases comparatively. Mainly the appearance of the ...
Control of a battery charger for electric vehicles with unity power factor
(Universidad Tecnológica de Bolivar, 2021-07)
En este trabajo se presenta una estrategia de control no lineal para un cargador de baterías de vehículos eléctricos. El controlador propuesto permite realizar la recarga del banco de baterías mediante un perfil de carga ...
Exploring the synthesis conditions to control the morphology of gold-iron oxide heterostructures
(Tsinghua Univ Press, 2019-06-11)
Gold–iron oxide nano-heterostructures with a clear and well-defined morphology were prepared via a seed-assisted method. The synthesis process and the events of heterogeneous nucleation during the decomposition of the iron ...
