Source time reversal (STR) method for linear elasticity 

Brevis, R.I.; Rodríguez-Rozas, A.; Ortega, J.H.; Pardo, D.Autoridad BCAM (2018)
We study the problem of source reconstruction for a linear elasticity problem applied to seismicity induced by mining. We assume the source is written as a variable separable function $\mathbf{f(x)}\>g(t)$ . We first present ...

A multi-objective memetic inverse solver reinforced by local optimization methods 

Gajda-Zagórska, E.; Schaefer, R.; Smolka, M.; Pardo, D.Autoridad BCAM; Alvarez-Aramberri, J.Autoridad BCAM (2016-09-01)
We propose a new memetic strategy that can solve the multi-physics, complex inverse problems, formulated as the multi-objective optimization ones, in which objectives are misfits between the measured and simulated states ...

Dimensionally adaptive hp-finite element simulation and inversion of 2D magnetotelluric measurements 

Alvarez-Aramberri, J.Autoridad BCAM; Pardo, D.Autoridad BCAM (2016-09-01)
Magnetotelluric (MT) problems often contain different subdomains where the conductivity of the media depends upon one, two, or three spatial variables. Traditionally, when a MT problem incorporates a three-dimensional (3D) ...

Quantities of interest for surface based resistivity geophysical measurements 

Alvarez-Aramberri, J.Autoridad BCAM; Bakr, S.A.; Pardo, D.Autoridad BCAM; Barucq, H. (2015-12-31)
The objective of traditional goal-oriented strategies is to construct an optimal mesh that minimizes the problem size needed to achieve a user prescribed tolerance error for a given quantity of interest (QoI). Typical ...

Multi-objective hierarchic memetic solver for inverse parametric problems 

Gajda-Zagórska, E.; Smolka, M.; Schaefer, R.; Pardo, D.Autoridad BCAM; Alvarez-Aramberri, J.Autoridad BCAM (2015-12-31)
We propose a multi-objective approach for solving challenging inverse parametric problems. The objectives are misfits for several physical descriptions of a phenomenon under consideration, whereas their domain is a common ...

An Agent-Oriented Hierarchic Strategy for Solving Inverse Problems 

Smolka, M.; Schaefer, R.; Paszynski, M.; Pardo, D.Autoridad BCAM; Alvarez-Aramberri, J.Autoridad BCAM (2015-12-31)
The paper discusses the complex, agent-oriented hierarchic memetic strategy (HMS) dedicated to solving inverse parametric problems. The strategy goes beyond the idea of two-phase global optimization algorithms. The global ...
