(IOP, 2021)We present a penalization parameter method for obstacle identification in an incompressible fluid flow for a modified version of the Oseen equations. The proposed method consists in adding a high resistance potential to ...
-
(IOP, 2022)In this work, we present a stability result for the inverse problem of recovering a smooth scalar permeability parameter given by the Brinkman's law applied to the steady Navier-Stokes equations from local observations of ...
-
(Universidad de Chile, 2022)En esta tesis se presentan nuevos avances en problemas inversos de Mecánica de Fluidos en estado estacionario, con aplicaciones directas en la recuperación de deformaciones de dominio y obstáculos, y cuyo propósito es ...
-
(Universidad de Chile, 2023)En el siguiente trabajo se presenta el algoritmo de Descenso de Gradiente Estocástico de Langevin (SGLD, sigla por su nombre en inglés), algoritmo de minimización basado en los algoritmos de descenso de gradiente estocástico ...
-
(Universidad de Chile, 2019)For the diagnosis, treatment planning and post-surgical monitoring of cardiovascular disease (CVD), hemodynamic markers have proven to be of great utility. However, non-invasive assessment of the hemodynamics of a patient ...
-
(Universidad de Chile, 2021)Both precision and spatial resolution of atmospheric data are fundamental aspects when evaluating air quality and the effects of different factors on the distribution of air pollutants. Satellite-borne instruments have ...
-
(Elsevier, 2022)While MRI allows to encode the motion of tissue in the magnetization's phase, it remains yet a challenge to obtain high fidelity motion images due to wraps in the phase for high encoding efficiencies. Therefore, we propose ...
-
(Nature, 2021)Dehydration of the oceanic subducting slab promotes the formation of magmatic arcs, intra-slab intermediate-depth seismicity, and hydration of the overlying mantle wedge. However, the complex permeability structure of the ...
