Stable tridimensional bubble clusters in multi-bubble sonoluminescence (MBSL)
(Elsevier Science, 2014-06)
In the present work, stable clusters made of multiple sonoluminescent bubbles are experimentally and theoretically studied. Argon bubbles were acoustically generated and trapped using bi-frequency driving within a cylindrical ...
Cross-frequency couplings in non-sinusoidal dynamics of interacting oscillators: Acoustic estimation of the radial position and spatial stability of nonlinear oscillating bubbles
(Elsevier Science, 2019-03)
In this work, the analysis of cross-frequency couplings (CFC) is introduced in the context of nonlinear acoustics related to the dynamics of bubble(s)-resonator systems. The results obtained from experiments specifically ...
Analytical study of the acoustic field in a spherical resonator for single bubble sonoluminescence
(Acoustical Society of America Institute of Physics, 2009-09)
The acoustic field in the liquid within a spherical solid shell is calculated. The proposed model takes into account Stoke?s wave equation in the viscous fluid, the membrane theory to describe the solid shell motion and the ...
Cross-frequency coupling and phase synchronization in nonlinear acoustics
(Acoustical Society of America, 2016-09-15)
The Cross-Frequency Coupling (CFC) characterizes the correlation between the phase/amplitude of a low-frequency band with those of a high-frequency band within or across time series. The CFC phenomenon has been observed ...
Diseño de cargador Off-Board para conexión domiciliaria de vehículos eléctricos a nivel nacional y control del fenómeno de burbujeo en inversores electrónicos de potencia

En esta tesis de maestría se realizan 2 estudios, en el primero de ellos se plantea el diseño de un cargador off-board para vehículos eléctricos afianzado al nivel eléctrico residencial de 120 V en Colombia. Este permite ...
Dynamic co-movement analysis among oil prices, green bonds, and CO2 emissions, 2014-2022
(Universidad Nacional de ColombiaMedellín - Minas - Doctorado en Ingeniería - Industria y OrganizacionesFacultad de MinasMedellín, ColombiaUniversidad Nacional de Colombia - Sede Medellín, 2023-05-29)
This research addresses the problem of the coverage gap in the extant literature to know how oil prices, green bonds, and CO2 emissions are related to each other. Additionally, to research the short and long-term relations ...
