(American Physical Society, 1990-02-19)We derive equations of motion for a diluted gas of spiral defects in the two-dimensional complex Ginzburg-Landau equation. The interaction of two defects is treated and our predictions agree with a recent numerical experiment.
-
(Copernicus Gesellschaft MBH, 2015)Glacier behaviour during the mid-Holocene (MH, 6000 years BP) in the Southern Hemisphere provides observational data to constrain our understanding of the origin and propagation of palaeoclimate signals. In this study we ...
-
(IEEE-Institute of Electrical and Electronics Engineers, 2020)Current ongoing industry revolution demands more flexible products, including robots in household environments and medium-scale factories. Such robots should be able to adapt to new conditions and environments and be ...
-
(Universidad de Chile, 2019)El Aprendizaje Reforzado Profundo (DRL) se ha transformado en una metodología poderosa para resolver problemas complejos de toma de decisión secuencial. Sin embargo, el DRL tiene varias limitaciones cuando es usado en ...

(American Geophysical Union, 2020)Understanding and characterizing the spatial distribution of snow are critical to represent the energy balance and runoff production in mountain environments. In this study, we investigate the interannual and seasonal ...
-
(2001-06-15)Altiplano, a semiarid, high-level plateau entrenched in the central Andes. On the interannual timescale, Altiplano rainfall exhibits pronounced fluctuations between drought and very wet conditions, with subsequent impacts ...

(John Wiley and Sons Ltd, 2019)© 2018 The Authors. Hydrological Processes published by John Wiley & Sons Ltd. We present a field-data rich modelling analysis to reconstruct the climatic forcing, glacier response, and runoff generation from a high-elevation ...
-
(AMER GEOPHYSICAL UNION, 2008-11-01)The coastal mountains of semiarid Chile are punctuated by patches of fog- dependent evergreen forests. Fog episodes often occur when the prominent coastal topography intercepts a well developed deck of stratocumulus (Sc) ...
-
(1999-10-01)Observations with a four-channel UV radiometer in Santiago, Chile (33.5øS, 70.6øW) from January 1992 to December 1998 are presented. Chinreels are centered at 305, 320, 340 and 380 nm with a 10 nm bandwidth. Measurements were ...
-
(Universidad de Chile, 2011)En el presente trabajo se busca desarrollar y montar una aplicación de posicionamiento autónomo sobre un dispositivo portátil y de arquitectura modular llamado BUG. El objetivo es poder llegar a obtener la información de ...
-
(Universidad de Chile, 2014)La diversidad cultural es una realidad social reconocida, latente e ineludible. En el mundo existe una multiplicidad de expresiones culturales que supera por lejos a la cantidad de Estados que las cobijan. Gestionar esta ...
-
(Universidad de Chile, 2019)Mientras que industrias como las aerolíneas, hoteles o cadenas de supermercado continúan desarrollando innovadoras estrategias de pricing, los bancos rara vez discuten nuevas estrategias de precios como una herramienta ...
-
(SPRINGER/PLENUM PUBLISHERS, 2006-10)In this paper the results of multiwavelength investigation of an unusual nebular object SNO 85 are presented. In 2MASS images this object looks like a star with a jet. In DSS2 R image the end of the jet is connected with ...
-
(Universidad de Chile, 2018)La presente tesis se centró en la implementación de Interés Complementario, un servicio tecnológico para OpinionZoom (OZ), proyecto académico con fines comerciales llevado a cabo por el Web Intelligence Centre (WIC) de la ...
-
(Universidad de Chile, 2016)La dinámica de interfases es un tópico de estudio que ha suscitado mucho interés en distintos contextos tales como el magnetismo, dinámica de poblaciones, óptica, por mencionar algunos. Una interfase es un borde o superficie ...
-
(Springer, 2020)We consider the wave equation epsilon(2)(-partial derivative(2)(t) + Delta)u + f(u) = 0 for 0 < epsilon << 1, where f is the derivative of a balanced, double-well potential, the model case being f(u) = u - u(3). For equations ...
