(Universidad de Chile, 2020)En la computación gráfica la cantidad de simulaciones y sus dimensiones ha crecido a lo largo del tiempo. Sus avances en diferentes áreas expresa la necesidad de que los algoritmos que procesan y visualizan la información ... -
Estudio de estructuras magmáticas bajo el volcán Láscar mediante datos de magnetotelúrica y geodesia
(Universidad de Chile, 2020)El volcán Láscar es un estratovolcán ubicado en el norte de Chile, al Este del Salar de Atacama. Es considerado por muchos autores, uno de los volcanes más activos de la Zona Volcánica Central (ZVC). Su actividad comienza ... -
Estudio de la electrodeposición de sulfuros de cobre para la fabricación de fotocátodos para la hidrólisis de agua en una celda fotoelectroquímica
(Universidad de Chile, 2020)El uso extensivo de combustibles fósiles ha provocado un nivel de emisiones de dióxido de carbono que contribuyen significativamente al fenómeno del cambio climático. Por lo que es necesario un cambio de combustibles por ... -
Global quieting of high-frequency seismic noise due to COVID-19 pandemic lockdown measures
(Amer Assoc Advancement Science, 2020)Human activity causes vibrations that propagate into the ground as high-frequency seismic waves. Measures to mitigate the coronavirus disease 2019 (COVID-19) pandemic caused widespread changes in human activity, leading ... -
Soil electrical resistivity monitoring as a practical tool for evaluating irrigation systems efficiency at the orchard scale: a case study in a vineyard in Central Chile
(Springer, 2021)In many orchards, irrigation scheduling is designed based on data from meteorological networks and considering homogeneous soil properties. Such assumptions may result in inefficient irrigation, which is difficult to ... -
Spitzer Reveals Evidence of Molecular Absorption in the Atmosphere of the Hot Neptune LTT 9779b
(IOP, 2020)Non-rocky sub-Jovian exoplanets in high-irradiation environments are rare. LTT 9779b, also known as Transiting Exoplanet Survey Satellite (TESS) object of interest (TOI) 193.01, is one of the few such planets discovered ... -
Transmission estimation at the cram´er-rao bound for squeezed states of light in the presence of loss and imperfect detection
(American Physical Society, 2020)Enhancing the precision of a measurement requires maximizing the information that can be gained about the quantity of interest from probing a system. For optical-based measurements, such an enhancement can be achieved ... -
Supershear frictional ruptures along bimaterial interfaces
(Amer Geophysical Union, 2020)We experimentally and analytically explore supershear ruptures that are excited at the onset of frictional motion within "bimaterial interfaces," frictional interfaces formed by contacting bodies having different elastic ... -
Valoración de un asiento de bus usando datos mixtos de preferencias reveladas y declaradas
(Universidad de Chile, 2020)En los últimos años se ha reconocido el papel de la comodidad para comprender las elecciones de rutas y modos de transporte. Este factor es tan importante para algunos viajeros que los lleva a tomar decisiones que no podrían ... -
Simulación numérica de impacto y adhesión de partículas esféricas
(Universidad de Chile, 2020)Uno de los tipos de manufactura que se ha hecho popular recientemente es la manufactura aditiva, debido a su gran rapidez para obtener resultados. La proyección térmica es uno de los procesos más utilizados de manufactura ... -
Optimización del proceso de solicitud de pedidos para franquicias de farmacias
(Universidad de Chile, 2020)Esta tesis trata la problemática de dos locales de franquicia de farmacia en la búsqueda de obtener un mejor margen (diferencia entre compra y venta), sin incluir sueldos, arriendos y gastos operaciones. Dentro de las ... -
Stein hypothesis and screening effect for covariances with compact support
(Inst Mathematical Statistics, 2020)In spatial statistics, the screening effect historically refers to the situation when the observations located far from the predict and receive a small (ideally, zero) kriging weight. Several factors play a crucial role ... -

Single-layer dichroic filters for multifrequency receivers at THz Frequencies
(IEEE, 2020)In this work, we report the design, construction, and characterization of two free-standing single-layer frequency-selective surface structures to be used as dichroic filters in the THz range. Their spectral responses are ... -
Provenance of northwestern Patagonian river sediments (44-48 degrees S): A critical evaluation of mineralogical, geochemical and isotopic tracers
(Elsevier, 2020)The ability to trace and quantify sediment provenance in northwestern Patagonia is increasingly needed to properly understand modem sediment erosion and transport processes in this rapidly changing environment, and to ... -
Progenitor properties of type II supernovae: fitting to hydrodynamical models using Markov chain Monte Carlo methods
(EDP Science, 2020)Context. The progenitor and explosion properties of type II supernovae (SNe II) are fundamental to understanding the evolution of massive stars. Particular attention has been paid to the initial masses of their progenitors, ... -
The stability for an inverse problem of bottom recovering in water-waves
(IOP, 2020)In this article we deal with a class of geometric inverse problem for bottom detection by one single measurement on the free surface in water-waves. We found upper and lower bounds for the size of the region enclosed between ... -
Non-Strategic capacity withholding from distributed energy storage within microgrids providing energy and reserve services
(MDPI, 2020)Microgrids have the potential to provide security and flexibility to power systems through the integration of a wide range of resources, including distributed energy storage, usually in the form of batteries. An aggregation ...
