(Science & Technology, 2021)We study the light curves of pulsating variable stars using a complex network approach to build visibility graphs. We consider various types of variables stars (e.g., Cepheids, delta Scuti, RR Lyrae), build two types of ...

(2007)A bidimensional cellular automaton model is used to simulate the process of evacuation of pedestrians in a room with fixed obstacles. A floor field is defined so that moving to a cell with lower floor field means approaching ...

Characterization of the nontrivial and chaotic behavior that occurs in a simple city traffic model (2010)Urban traffic is interesting not only due to its obvious social and economical impact, but also due to its complexity. It is not unusual for drivers to get stuck in a traffic jam that apparently emerged from nowhere. ...
-
(Elsevier, 2014)We simulate traffic in a city by means of the evolution of a row of interacting cars, using a cellular automaton model, in a sequence of traffic lights synchronized by a ‘‘green wave’’. When our initial condition is a ...

(Universidad de Chile, 2022)En esta tesis estudiamos las variaciones de la intensidad del campo magn´etico terrestre (CMT) utilizando t´ecnicas de redes complejas. Espec´ıficamente se realiz´o un estudio de comunidades sobre una red compleja a ...
-
(American Geophysical Union, 2015)Observed electron velocity distributions in the Earth's magnetosphere and the solar wind exhibit a variety of nonthermal features which deviate from thermal equilibrium, for example, in the form of temperature anisotropies, ...
-
(Universidad de Chile, 2015)En el proceso para entender el flujo granular en diferentes sistemas ha habido diferentes acercamientos desde la hidrodinámica clásica, la teoría cinética y la teoría de fluctuaciones hidrodinámicas, de modo de obtener ...
-
(Universidad de Chile, 2021)Los plasmas con partículas de polvo han sido objeto de una gran cantidad de investigaciones debido a su relevancia y utilidad a la hora de modelar diferentes sistemas tanto en escenarios teóricos como experimentales. La ...
-
(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 ...
-
(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 ...
-
(European Geosciences Union&the American Geophysical Union, 2014)Abstract. Propagation of large-amplitude waves in plasmas is subject to several sources of nonlinearity due to relativistic effects, either when particle quiver velocities in the wave field are large, or when thermal ...
-
(Elsevier, 2013)We explore the nontrivial behavior of a particular city traffic model due to its minimalistic representation of basic city traffic dynamics. The chaotic behavior is studied through the supertrack functions, an approach ...
-
(EUROPEAN GEOSCIENCES UNION, 2006)The nonextensive statistics formalism proposed by Tsallis has found many applications in systems with memory effects, long range spatial correlations, and in general whenever the phase space has fractal or multi-fractal ...
-
(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 ...
-
(2014)Divorced individuals face complex situations when they have children with different ex-partners, or even more, when their new partners have children of their own. In such cases, and when kids spend every other weekend ...
-
(American Physical Society, 2014)In the hope of making passenger travel times shorter and more reliable, many cities are introducing dedicated bus lanes (e.g., Bogota, London, Miami). Herewe showthat chaotic travel times are actually a natural consequence of ...
-
(Universidad de Chile, 2007)En el presente trabajo se estudia la dinámica de suspensiones en un sistema cuasi bidimensional (celda de Hele-Shaw), considerando partículas no Brownianas inmersas en un fluido viscoso confinado entre dos paredes infinitas, ...
-
(American Physical Society, 2014)A kinetic description of Alfvén-cyclotron magnetic fluctuations for anisotropic electron-proton quasistable plasmas is studied. An analytical treatment, based on the fluctuation-dissipation theorem, consistently shows ...
-
(American Geophysical Union, 2014)The study of complexity in two aspects of the magnetic activity in the Sun-Earth system is presented. We compare the temporal evolution of the magnetic fluctuations in the Earth’s magnetosphere and the spatial distribution ...
