Optimal control approach for moving bottom detection in one-dimensional shallow waters by surface measurements
Gino Montecinos, Rodrigo Lecaros, Juan López-Ríos +1
We consider the Boussinesq-Peregrine (BP) system as described by Lannes [Lannes, D. (2013). The water waves problem: mathematical analysis and asymptotics (Vol. 188). American Math…
Discrete Carleman estimates and application to controllability for a fully-discrete parabolic operator with dynamic boundary conditions
Rodrigo Lecaros, Roberto Morales, Ariel Pérez +1
We consider a fully-discrete approximations of 1-D heat equation with dynamic boundary conditions for which we provide a controllability result. The proof of this result is based o…
A fast algorithm of the shear-compression damage model for the simulation of block caving
Sergio Gaete, Alejandro Jofre, Rodrigo Lecaros +4
For underground mine, the current usual technique for ore extraction is block caving, which generates and induces seismic activity in the mine. To understand block caving method is…
A shear-compression damage model for the simulation of underground mining by block caving
Eric Bonnetier, Sergio Gaete, Alejandro Jofre +5
Block caving is an ore extraction technique used in the copper mines of Chile. It uses gravity to ease the breaking of rocks, and to facilitate the extraction from the mine of the…
Assessment of event-triggered policies of nonpharmaceutical interventions based on epidemiological indicators
Carla Castillo-Laborde, Taco de Wolff, Pedro Gajardo +3
Nonpharmaceutical interventions (NPI) such as banning public events or instituting lockdowns have been widely applied around the world to control the current COVID-19 pandemic. Typ…
The stability for an inverse problem of bottom recovering in water-waves
R. Lecaros, J. López-Ríos, J. H. Ortega +1
In this article we deal with a class of geometric inverse problem for bottom detection by one single measurement on the free surface in water--waves. We found upper and lower bound…
An inverse problem for Moore-Gibson-Thompson equation arising in high intensity ultrasound
Rogelio Arancibia, Rodrigo Lecaros, Alberto Mercado +1
In this article we study the inverse problem of recovering a space-dependent coefficient of the Moore-Gibson-Thompson (MGT) equation, from knowledge of the trace of the solution on…
A numerical procedure and unified formulation for the adjoint approach in hyperbolic PDE-constrained optimal control problems
Gino I. Montecinos, Juan Lopez-Rios, Jaime H. Ortega +1
The present paper aims at providing a numerical strategy to deal with PDE-constrained optimization problems solved with the adjoint method. It is done through out a unified formula…
Predictive Index for slope instabilities in open pit mining
J. H. Ortega, M. Rapiman, R. Lecaros +3
In this paper we study the stability and deformation of structures, in particular the wall of an open pit mine is studied by using information obtained from a variety of remote sen…
Control of underwater vehicles in inviscid fluids--II. Flows with vorticity
Rodrigo Lecaros, Lionel Rosier
In a recent paper, the authors investigated the controllability of an underwater vehicle immersed in an infinite volume of an inviscid fluid, assuming that the flow was irrotationa…
Determination of the calcium channel distribution in the olfactory system
C. Conca, R. Lecaros, J. H. Ortega +1
In this paper we study a linear inverse problem with a biological interpretation, which is modeled by a Fredholm integral equation of the first kind. When the kernel in the Fredhol…
Control of Underwater Vehicles in Inviscid Fluids. I: Irrotational Flows
Rodrigo Lecaros, Lionel Rosier
In this paper, we investigate the controllability of an underwater vehicle immersed in an infinite volume of an inviscid fluid whose flow is assumed to be irrotational. Taking as c…
