(Elsevier, 2019)After the 2010 Maule, Chile, earthquake (Mw 8.8), several reinforced concrete (RC) buildings presented damage in some walls (crushing of concrete, buckling and fracture of steel reinforcement). These buildings had been ...
-
(ELSEVIER, 2006-03)Ultrasound scattering is used to characterize instability modes in a laminar axisymmetric thermal plume subjected to controlled axisymmetric ("varicose") disturbances. A scattered signal is detected as soon as vortical ...

(Elsevier, 2017)One of the commonly used stabilization systems for rock tunnels is shotcrete. This fine aggregate mortar is usually reinforced for improving its tensile and shear strength. In deep tunnels, its capacity to absorb energy ...
-
(Elsevier, 2011)This paper presents the results from a series of experimental tests carried out to determine the damping characteristics of a section of a 375 m long pile-supported wharf structure under forced excitation. The test program ...

(IWA PublishingAlliance House, 2018-07)Water loss from leaking pipes represents a substantial loss of revenue as well as environmental and public health concerns. Leak location is normally identified by placing sensors either side of the leak and recording and ...
-
(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, ...
