(Universidad de Chile, 2013)El objetivo de esta Tesis es dar una descripción sobre los comportamientos no variacionales mostrados por sistemas extendidos que presentan patrones como soluciones de equilibrio. En particular, se estudiaron dos fenómenos ...
-
(American Physical Society, 2015)The Ehrenfest urn model is extended to a complex directed network, over which a conserved quantity is transported in a random fashion. The evolution of the conserved number of packets in each urn, or node of the network, ...
-
(American Chemical Society, 2016-10-20)The potential and properties of palladium hollow nano particles (hNPs) as a possible H storage material are explored by means of classical molecular dynamics (MD) simulations. First, we study the stability of pure Pd hNPs ...
-
(SPRINGER, 2006)The magnetosphere is a multi-scale spatio-temporal complex dynamical system. Self-organization is a possible solution to the seemingly contradicting observation of the repeatable and coherent substorm phenomena with ...
-
(Elsevier, 2020)Imogolite is a fascinating inorganic nanotube that is found in nature or synthesized in a laboratory. The synthesis process is carried out in liquid media, and leads to the formation of almost monodisperse diameter nanotubes. ...
-
(American Chemical Society, 2017)The large surface-to-volume ratio of hollow palladium nanoparticles (hNPs) offers room to improve their hydrogen storage capacity as well as their catalytic activity. However, a less explored possibility is to use, in ...
-
(Blackwell Publishing Ltd, 2003)In a recent study of ion cyclotron waves generated by the thermal anisotropy of oxygen ions, it was shown that the heavy ion drift velocity and a large thermal anisotropy of the heavy ions can destabilize proton-cyclotron ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2005-11)Copper was removed from an acidic mine drainage (AMD) using a liquid emulsion membrane contactor. The acidic drainage was a harmful natural acidic solution generated by bioleaching and chemical leaching of copper and iron ...
-
(Oxford University Press, 2017)As another step towards understanding the long-term evolution of the magnetic field in neutron stars, we provide the first simulations of ambipolar diffusion in a spherical star. Restricting ourselves to axial symmetry, ...
-
(EDP SCIENCES S A, 2008-09)Aims. This paper is the first in a series that aims to understand the long-term evolution of neutron star magnetic fields. Methods. We model the stellar matter as an electrically neutral and lightly-ionized plasma composed ...
-
(Elsevier, 2016)The observations in the solar wind, which are usually organized in a beta-anisotropy diagram, seem to be constrained by linear instability thresholds. Unexpectedly, under these quasi-stable conditions, there is a finite ...
-
(American Chemical Society, 2016)The mechanical response of aluminosilicate nano tubes (imogolite) under compression is investigated by means of classical molecular dynamics simulations using the CLAYFF potential. Using the uncompressed length L-0, when ...
-
(Amer Inst Physics, 2015)We propose a model of a bus traveling through a sequence of traffic lights, which is required to stop between the traffic signals to pick up passengers. A two dimensional model, of velocity and traveled time at each traffic ...
-
(2007)A simplified traffic model is studied, consisting of two vehicles traveling through a sequence of crossroads regulated by yield signs. A car approaching a yield sign stops if, in the other street, there is a car closer ...
-
(2011)Statistical and fractal properties of the spatial distribution of earthquakes in the central zone of Chile are studied. In particular, data are shown to behave according to the well-known Gutenberg-Richter law. The fractal ...
-
(Amer Physical Soc, 2016)The particle-particle interaction potential of an N-atom cluster is expanded in n-body contributions. The expansion allows us to determine the magnitude of each one of the n-body terms, and consequently quantifies how ...
-
(2012)Collision processes between single gold and rhodium atoms and gold and rhodium nanoclusters, respectively, are used to study the interplay between the large elastic energies and the much smaller magnetic interactions. The ...
-
New opportunities offered by Cubesats for space research in Latin America: The SUCHAI project case (Elsevier, 2016)During the last decade, a very small-standardized satellite, the Cubesat, emerged as a low-cost fast-development tool for space and technology research. Although its genesis is related to education, the change in paradigm ...
-
(IOP PUBLISHING, 2015)Upper main-sequence stars, white dwarfs, and neutron stars are known to possess stable, large-scale magnetic fields. Numerical works have confirmed that stable magnetohydrodynamic equilibria can exist in non-barotropic, ...
-
(AMER INST PHYSICS, 2008-07-21)We describe a simple method to control a known unstable periodic orbit UPO in the presence of noise. The strategy is based on regarding the control method as an optimization problem, which allows us to calculate a ...
