(Universidad de ChilePrograma Cybertesis, 2008)Se sabe que la plasticidad en cristales, particularmente en metales, depende fuertemente del comportamiento de dislocaciones. De hecho hay importantes interrogantes en Ciencias de Materiales, por ejemplo relacionadas con ...
-
(Universidad de Chile, 2014)El trabajo desarrollado tiene la finalidad de encontrar una nueva herramienta para desarrollar la toma de decisiones por parte de un robot que juega fútbol. En el transcurso de los avances en robótica, han sido muchos los ...
-
(Universidad de Chile, 2016)En los Andes Centrales las estructuras compresivas presentan variaciones a lo largo del rumbo en su geometría y cinemática. Ejemplo de ello son las estructuras de orientación NNE SSW que involucran al basamento paleozoico ...

(Universidad de Chile, 2019)SQM, empresa productora más grande de litio en Chile, se encuentra desarrollando pruebas de flotación de espodumeno (LiAl (SiO_3 )_2 ), utilizando agua de sitio y ácido oleico (AO) como colector. El agua de sitio se ...
-
(Universidad de ChilePrograma Cybertesis, 2008)El objetivo de esta tesis es analizar la posibilidad que existan en equilibrio inversionistas irracionales, quienes presentan persistencia, anclaje y sobrerreacción en la formación de sus creencias, elementos conductuales ...
-
(Universidad de Chile, 2012)En esta tesis se estudian dos sistemas fuera del equilibrio: una capa de agua vibrada vertical- mente que exhibe solitones hidrodinámicos no propagativos y un cristal líquido nemático al que se le aplica un campo ...
-
(Institute of Mathematical Statistics, 2016)In this paper, we investigate a model for a 1 1 dimensional self interacting and partially directed self-avoiding walk, usually referred to by the acronym IPDSAW. The interaction intensity and the free energy of the system ...
-
(The American Astronomical Society, 2013-04)We report the results of a three-year-long dedicated monitoring campaign of a restless luminous blue variable (LBV) in NGC 7259. The object, named SN 2009ip, was observed photometrically and spectroscopically in the optical ...
-
(Elsevier B.V., 2019)© 2019 Elsevier LtdNon mammalian gelatin under low moisture conditions could potentially be used in encapsulation technologies in food and pharmaceutical applications. This work explored the interactions between salmon ...
-
(Elsevier, 2017)Trypsin is a protease widely used in several industrial areas for leather and meat softening and to produce enzymatic detergents, among others applications. The high demand for this enzyme has motivated the development of ...
-
(Elsevier, 2020)The dynamics of ecological systems are often described by integrodifferential equations that incorporate nonlocal interactions associated with facilitative, competitive interactions between plants, and seed dispersion. In ...
-
(2007)The scattering of a surface wave by a pinned edge dislocation in a semi-infinite, homogeneous, isotropic, three-dimensional elastic solid is investigated analytically and numerically. An incident wave excites the dislocation ...
-
(Springer, 2015)The Campo de Dalı´as (Almerı´a, south-eastern Spain) was the backdrop for the development of intensive agricultural activity during the 1970s. Due to the poor natural soil development, the agriculturalists opted for ...
-
(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 ...
