(Universidad de Chile, 2021)La medición de la posición de los astros es un tema fundamental en múltiples áreas de la astronomía, especialmente en la astrometría, cuyo desarrollo depende de la obtención de mejores imágenes con mayor calidad utilizando ...
-
(Springer, 2020)Coarse arches are a common issue in caving mines where large fragments are expected. These arches interrupt ore flow in drawpoints, decreasing available draw area, and also increasing the possibility of non-uniform draw, ...
-
(Optical Soc Amer, 2020)We investigate the interplay between two fundamentally different localization mechanisms in discrete systems: dynamic localization, i.e., resonant wave packet revivals in periodically driven lattices, and Anderson localization, ...
-
(Springer Netherlands, 2019)Reinforcing bars removed from structural walls that belonged to a damaged building during the 2010 earthquake in Chile are studied under low-cycle fatigue testing. Damage of such walls was characterized by concrete crushing ...
-
(Academic Press, 2019)This work presents a comprehensive study of the uncertainties involved in the FrequencyResponse Function (FRF) of Piezoelectric Energy Harvesters (PEHs) based on experimentalresults. A proper experimental setup is designed ...
-
(Universidad de Chile, 2019)Esta tesis consiste en un estudio experimental de estados dinámicamente hiperuniformes, llevado a cabo mediante la caracterización de las fluctuaciones de densidad en un sistema granular vibrado de geometría cuasi-bidimensional. ...
-
(IEEE, 2021)In a hybrid modular multilevel converter (MMC), capacitor voltage balance between the Full-Bridge Sub-Modules (FBSMs) and Half-Bridge Sub-Modules (HBSMs) is only possible when the arm currents are bipolar. For a grid-connected ...
-
(The Royal Society, 2015)We report laboratory experiments on surface waves generated in a uniform fluid layer whose bottom undergoes an upward motion. Simultaneous measurements of the free-surface deformation and the fluid velocity field are focused ...
-
(Amer Mathematical Soc, 2018)We give a simple alternative proof for the C-1,C-1-convex extension problem which has been introduced and studied by D. Azagra and C. Mudarra (2017). As an application, we obtain an easy constructive proof for the ...
-
(Springer-Verlag, 2009)A mobile robot has always uncertainty about the world model. Reducing this uncertainty is very hard because there is a huge amount of information and the robot must focus on the most relevant one. The selection of the most ...
-
(Institute of Electrical and Electronics Engineers Inc., 2018)Computing the product of the (binary) adjacency matrix of a large graph with a real-valued vector is an important operation that lies at the heart of various graph analysis tasks, such as computing PageRank. In this paper ...
-
(IEEE, 2017)In this paper, we consider the deployment of multiple antennas as a way to exploit spatial diversity in the uplink of multiple access systems that adopt low-density spreading (LDS) with orthogonal frequency-division ...
-
(Wiley, 2021)In the last decade, Bayesian networks (BNs) have been widely used in engineering risk assessment due to the benefits that they provide over other methods. Among these, the most significant is the ability to model systems, ...
-
(Springer Verlag, 2019)Extreme environments are a unique source of microorganisms encoding metabolic capacities that remain largely unexplored. In this work, we isolated two Antarctic bacterial strains able to produce poly(3-hydroxyalkanoates) ...
-
(Universidad de Chile, 2014)El presente trabajo busca identificar y explicar la generación de anomalías geoquímicas en superficie producto de la presencia de yacimientos sulfurados de Cu bajo la cobertura sedimentaria, siendo sometidos a procesos de ...
-
(Universidad de ChileCyberDocs, 2011)El blanco Pulucktur corresponde a un sector cubierto por calizas y sedimentos continentales sub horizontales del Mioceno al Pleistoceno. Se sitúa a 7 km. al suroeste de Calama, en la II Región. En este blanco, entre julio ...
-
(Universidad de Chile, 2022)El resaltado de sintaxis permite a los programadores videntes explorar código y obtener información contextual de manera eficiente. Sin embargo, cuando se trata de programadores ciegos, no existe un estándar definido con ...
-
(Universidad de ChilePrograma Cybertesis, 2007)
-
(Universidad de Chile, 2023)El contexto sismológico de Chile origina un área de estudio donde es necesario asegurar un adecuado comportamiento estructural ante solicitaciones sísmicas. En general, la investi- gación en el ámbito estructural es ...
-
(Universidad de Chile, 2018)El sensoramiento remoto en el rango de las microondas y su relación con las propiedades físicas del manto de nieve han sido ampliamente estudiados en los últimos años. Sin embargo, no ha sido evaluada en la Cordillera de ...
