Aguayo Araneda, Jorge Sebastián; Bertoglio, Cristóbal; Osses Alvarado, Axel Esteban (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 ...

Aguayo Araneda, Jorge Sebastián; Osses Alvarado, Axel Esteban (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 ...

Herthum, Helge; Carrillo Lincopí, Hugo Patricio Anner; Osses Alvarado, Axel Esteban; Uribe, Sergio; Sacka, Ingolf; Bertoglio, Cristóbal (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 ...

Contreras Reyes, Eduardo Eliseo; Díaz, D.; Bello González, Juan Pablo; Slezak, Katarzyna Anna; Potin, Bertrand Jean-Maurice; Comte Selman, Diana Patricia; Maksymowicz Silva, Ana Maria; Ruiz, J. A.; Osses Alvarado, Axel Esteban; Ruiz, S. (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 ...
