(Royal Society Publishing, 2018)Order–disorder phase transitions driven by temperature or light in soft matter materials exhibit complex dissipative structures. Here, we investigate the spatio-temporal phenomena induced by light in a dye-doped nematic ...
-
(American Physical Society, 2014)Macroscopic magnetic systems subjected to external forcing exhibit complex spatiotemporal behaviors as result of dissipative self-organization. Pattern formation from a uniform magnetization state, induced by the combination ...
-
(Springer, 2017)Within the earth's atmosphere, methane (CH4) is one of the most important absorbers of infrared energy. It is recognized that coastal areas contribute higher amounts of CH4 emission; however, there is a lack of accurate ...
-
(SPRINGER, 2005-06)Water and dissolved ion transport in mineral tailings was studied at laboratory scale with three different tailings samples. Percolation rate, determined in column experiments, depends mainly on the granulometric distribution ...
-
(UNIV CHICAGO PRESS, 2000-12-10)Observations of the diffuse X-ray background at energies similar to3/4 and 1.5 keV show a large region of enhanced emission around the Galactic center. The origin of this X-ray enhancement is not known, but the best ...
-
(EDP Sciences S A, 2021)Aims. Distances are key to determining the physical properties of sources. In the Galaxy, large (>10 000) homogeneous samples of sources for which distance are available, covering the whole Galactic distance range, are ...
-
(The American Astronomical Society, 1988-10-15)New 6 cm continuum and radio recombination line VLA observations as well as CO observations are presented of the bright PN NGC 6302. The H110-alpha line is significantly broader than the H76-alpha line, an effect which is ...
-
(2001-09-10)We present optical and infrared spectroscopy of the first 2 months of evolution of the Type II supernova SN 1999em. We combine these data with high-quality optical/infrared photometry beginning only 3 days after shock ...
-
(UNIV CHICAGO PRESS, 2008-08-10)We present distance estimates for 11 peculiar Virgo Cluster spiral galaxies based on measurements of the stellar kinematics of their central 2 kpc. Stellar circular velocities were obtained using two- integral dynamical ...
-
(UNIV CHICAGO PRESS, 1994-09-01)We have used observations gathered at CTIO to measure distances by the expanding photosphere method (EPM) to five Type II supernovae. These supernovae lie at redshifts from cz = 1100 km s-1 to cz - 5500 km s-1, and increase ...
-
(SPRINGER, 2006-06)In order to produce a certain vector of flows over a fixed-size network, a transport firm has to choose, among many other things, a route structure. In accommodating increasing traffic, transport firms will adjust their ...
-
(Universidad de ChileCyberDocs, 2010)El tema principal de esta tesis es estudiar la dinámica de poblaciones basados en procesos de ramificación discretos, en particular se estudiaron los procesos de Bienaymé-Galton-Watson (BGW). El problema de extinción o ...
-
(Universidad de Chile, 2017)En la presente tesis se estudian las distribuciones cuasi-estacionarias para el proceso de Bessel en el intervalo (0,1]. Este proceso corresponde a una difusión uni-dimensional con coeficiente de drift singular en 0, la ...
-
(CENIM, 2008-05)En este trabajo, se caracteriza la distribución de tamaño de burbujas en una celda de flotación, tanto a escala industrial como a escala de laboratorio. En los casos experimentales, los tamaños de burbuja se miden vía ...
-
(Universidad de Chile, 2014)El Estado debe contar con instrumentos administrativos descentralizados que sean capaces de aprovechar los recursos económicos y socio-culturales que están asentados en el territorio. En el caso chileno, aquello es más ...
-
(Universidad de Chile, 2016)La aplicación de tomografías sísmicas en sistemas volcánicos e hidrotermales permite inferir propiedades físicas y litológicas del área estudiada a partir de la distribución 3D de velocidades sísmicas y sus variaciones. ...
-
(Universidad de Chile, 2017)El sector Chivato es un blanco de exploración de cobre, ubicado en la cordillera de la Costa, región de Atacama. El área de estudio cuenta con escasos antecedentes geológicos: no hay información publicada sobre unidades ...
