(Universidad de Chile, 2009)Uno de los principales factores que modifica el transporte de sustancias en aguas someras es la presencia de fuertes cambios laterales de la sección transversal, los cuales generan zonas de recirculación de gran escala ...
-
(The American Physical Society, 2022)We reveal unconventional edge states in a one-dimensional Stub lattice of coupled waveguides with staggered hoppings. The edge states appear for the same values of hoppings as topological edge states in the Su-Schrieffer-Heeger ...

Experimental observation of front propagation in a negatively diffractive inhomogeneous Kerr cavity (American Physical Society, 2014)A focusing Kerr Fabry-P´erot cavity operating in a negative diffraction regime exhibits transverse propagating fronts connecting two different nematic liquid crystal molecule average orientations. Under an inhomogeneous spatial ...
-
(IOP Publisihing, 2015)We investigate for the first time the motion, interaction and simultaneous collision between three initially stable vortex rings arranged symmetrically, making an angle of 120 degrees between their straight path lines. ...

Experimental Parameter Extraction in the Single-Diode Photovoltaic Model via a Reduced-Space Search (IEEE, 2017)The behavior of a photovoltaic (PV) module may be captured via its current-voltage (I-V) characteristic. The single-diode model is able to adequately fit this characteristic while featuring limited parameterization difficulty, ...
-
(Elsevier, 2017)Prequalification of the Double Split Tee (DST) connection has been conducted using hot-rolled shapes, whose availability is still limited in several countries. In addition, the range of available T web and flange thicknesses ...

(Elsevier, 2020)Usually in block and panel caving mines, when the caving connects to the surface, monitoring of vertical stresses over production drifts is minimal due to the low probability of seismic events. However, when the stresses ...
-
(Springer Netherlands, 2018)RC structural slender walls under large seismic excitation are expected to reach base moment capacity mainly affected by the first vibration mode. However, the base shear could be affected by higher modes once yielding in ...
-
(Elsevier, 2014)Caving methods rely on gravity to break up and transport large amounts of ore and waste. Massive underground mining is becoming even more prevalent due to the depletion of surface mining reserves. It is thus relevant to ...
-
(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 ...
