Balabanov, Oleg (Data de defensa: 2019-10-11)
Solutions to high-dimensional parameter-dependent problems are in great demand in the contemporary applied science and engineering. The standard approximation methods for parametric equations can require computational ...
Gobbi, Andressa (Data de defensa: 2019-01-25)
A significant part of the pathologies found in concrete dams is related with the presence of unsound aggregates that react with the cement paste. Such reactions may lead to expansions, causing damage and compromising the ...
Valhondo, Cristina (Data de defensa: 2017-02-03)
Artificial recharge of aquifers through infiltration basins (AR) improves water quality and in- creases groundwater resources, which make of it an appropriate technique for the renaturalization of waters affected directly ...
Moaven, Arash (Data de defensa: 2023-07-04)
(English) The Proper Generalized Decomposition (PGD) is a mathematical framework belonging to the Model Order Reduction (MOR) class of techniques. To the best of the author's knowledge, this methodology has not been applied ...
Bellido Recoder, Lucía (Data de defensa: 2021-10-25)
Railway bridges located at seismic zones are particularly complex structures that present exceptional difficulties due to the existence of the track and the phenomena associated to it called track-bridge interaction. The ...

The efficient and equitable use of urban road space considered as a public good and a scarce resource, leads to giving priority to sustainable transport modes (walking, cycling and public transport). Private vehicle sees ...
Malik, Muhammad Haris (Data de defensa: 2017-02-28)
This thesis presents the study of the model order reduction for power grids and transmission networks. The specific focus has been the transient dynamics. A mathematical viewpoint has been adopted for model reduction. Power ...
Pujol Sánchez, Mireia (Data de defensa: 2018-06-26)
The use of externally bonded fibre reinforced polymers, FRP, for strengthening reinforced concrete (RC) beams or columns is an alternative to other traditional strengthening techniques due to its high strength-to-weight ...
Cots Corominas, Carles (Data de defensa: 2022-05-06)
