Advanced techniques for solving groundwater and surface water problems in the context of inverse methods and climate change.

Todaro, Valeria (Universitat Politècnica de València, 2021-05-17)

[ES] El tema de la investigación se centra en técnicas avanzadas para manejar problemas de aguas subterráneas y superficiales relacionados con métodos inversos y cambio climático. Los filtros de Kalman, con especial atención ...
Characterizations of {K,s+1}-Potent Matrices and Applications

Lebtahi Ep-Kadi-Hahifi, Leila; Romero Martínez, José Oscar; Thome, Néstor (Elsevier, 2012-01-15)

Recently, situations where a matrix coincides with some of its powers have been studied. This kind of matrices is related to the generalized inverse matrices. On the other hand, it is possible to introduce another class ...
Experimental design of dynamic model-based damage identification in piezoelectric ceramics

Rus, Guillermo; Palma, Roberto; Pérez-Aparicio, José L. (ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2012)

[EN] A model-based inverse problem strategy is proposed for damage characterization, starting from the electromechanical response measurement as input data, and incorporating a numerical model that simulates the piezoelectric ...
Fast exact variable order affine projection algorithm

Ferrer Contreras, Miguel; Gonzalez, Alberto; Diego Antón, María de; Piñero Sipán, María Gemma (Elsevier, 2012-09)

Variable order affine projection algorithms have been recently presented to be used when not only the convergence speed of the algorithm has to be adjusted but also its computational cost and its final residual error. These ...
Identifiability for a Class of Discretized Linear Partial Differential Algebraic Equations

Cantó Colomina, Begoña; Coll, Carmen; Sánchez, Elena (Hindawi Publishing Corporation, 2011)

This paper presents the use of an iteration method to solve the identifiability problem for a class of discretized linear partial differential algebraic equations. This technique consists in replacing the partial derivatives ...
Inverse problems in engineering

Llopis Albert, Carlos; Palacios Marqués, Daniel (Edure Academy, 2016)

[EN] An inverse problem in engineering is the process of obtaining from a set of observations the causal factors that produce those data. Contrary to forward problems, an inverse problem starts with the results and ...
On the use of stochastic spectral methods in deep excavation inverse problems

Canavate-Grimal, Antonio; Falcó, Antonio; Calderón García, Pedro Antonio; Paya-Zaforteza, Ignacio (Elsevier, 2015-10)

The back analysis or inverse analysis of the field instrumentation data is a common technique to ascertain the design parameter validity in deep excavation projects. That analysis is a process full of uncertainties and ...
Study of hysteretic thermoelectric behavior in photovoltaic materials using the finite element method, extended thermodynamics and inverse problems

Palma, Roberto; Pérez-Aparicio, José L.; Bravo, R. (Elsevier, 2013-01)

The main objective of the present work is to develop and prove a theoretical explanation based on the Extended Non-Equilibrium Thermodynamics (ENETs) for the hysteretical thermoelectric behavior observed in certain ...
