(Universidad de Chile, 2020)The present work is the result of a detailed analysis of the occurrence of failure/degradation modes found in 95 solar photovoltaic modules operating in the Atacama Desert. The data was collected using an IDCTool (Inspection ...
-
(Elsevier, 2020)Three amphiphilic carbon nanotube-supported Ni catalysts have been prepared and tested regarding their emulsifying properties for the hydrogenation of furfural. The solid catalysts and emulsions were systematically ...
-
(Copernicus Gesellschaft MBH, 2020)Recently, it has been shown theoretically how the lithospheric stress changes could be linked with magnetic anomalies, frequencies, spatial distribution and the magneticmoment magnitude relation using the electrification ...
-
(Universidad de Chile, 2020)Las micro-redes han tenido un aumento en su utilización, debido a que representan una solución económica, que permite la incorporación de las energías renovables y que es capaz de abastecer de energía eléctrica a sectores ...
-
(Universidad de Chile, 2020)Con el fin de analizar el proceso de subducción de las placas de Nazca y Sudamérica en la zona de Los Andes del Sur, y su relación con el régimen tectónico y volcánico del lugar, se hicieron mediciones de magnetotelúrica ...
-
(Elsevier, 2020)The present investigation reports the modification of Ti substrates by a plasma technique to enhance their physio-chemical properties as biocompatible substrates for the deposition of artificial membranes. For that purpose, ...
-
(Elsevier, 2020)The design of water and energy systems has traditionally been done independently or considering simplified interdependencies between the two systems. This potentially misses valuable synergies between them and does not ...
-
(Springer, 2020)Random fields on the sphere play a fundamental role in the natural sciences. This paper presents a simulation algorithm parenthetical to the spectral turning bands method used in Euclidean spaces, for simulating scalar- ...
-
(Oxford University Press, 2020)Some universal solutions are studied for a new class of elastic bodies, wherein the Hencky strain tensor is assumed to be a function of the Kirchhoff stress tensor, considering in particular the case of assuming the bodies ...
-
Seawater flocculation of clay-based mining tailings: Impact of calcium and magnesium precipitation (Elsevier, 2020)In areas where access to water of good quality is limited, the use of seawater in mineral processing can be an option. However, the dewatering of waste tailings is adversely affected, particularly when this follows processing ...
-
(Elsevier, 2020)Reinforcement learning (RL) provides an alternative method for designing condition-based decision making in engineering systems. In this study, a simple and flexible RL tabular Q-learning framework is employed to identify ...
-
(Elsevier, 2020)Perfect graphs form a well-known class of graphs introduced by Berge in the 1960s in terms of a min-max type equality involving two famous graph parameters. In this work, we survey certain variants and subclasses of perfect ...
-
(IOP Publishing, 2020)We present evidence for localized deviations from Keplerian rotation, i.e., velocity "kinks," in 8 of the 18 circumstellar disks observed by the DSHARP program: DoAr 25, Elias 2-27, GW Lup, HD 143006, HD 163296, IM Lup, ...

(Universidad de Chile, 2020)El estudio y caracterización de parámetros de la fuente sísmica es un tópico fundamental en sismología, pues a partir de ésta se pueden comprender los procesos físicos de la ruptura y las características de cada terremoto. ...
-
(Universidad de Chile, 2020)En este trabajo se estudian problemas de coloración en grafos pigmentados. Un grafo pigmentado es una tupla $(G,c)$ con $G$ un grafo y $c:E(G)\to \NN$ una asignación de pigmentos en las aristas. El primer capítulo se centra ...
-
(Universidad de Chile, 2020)El presente trabajo consiste en la implementación de un método de medición de movimiento a partir de registros de video obtenidos por cámaras comercialmente asequibles. Este método se caracteriza por usar la fase del ...
-
(Universidad de Chile, 2020)El siguiente trabajo explora a través de un modelo de incentivos con crecimientos exponenciales la posibilidad de generar un aumento significativo en los niveles productivos de la línea de pintura de Hunter Douglas. Se ...
-
(Elsevier, 2020)Micro-reversibility plays a central role in thermodynamics and statistical mechanics. It is used to prove that systems in contact with a thermal bath relax to canonical ensembles. However, a problem arises when trying to ...
-
(Springer, 2020)We provide some necessary and sufficient conditions for a proper lower semicontinuous convex function, defined on a real Banach space, to be locally or globally Lipschitz continuous. Our criteria rely on the existence of ...
