Zorrilla Martínez, Rubén (Date of defense: 2020-09-21)
This thesis develops a numerical tool (the Virtual Wind Tunnel, VWT) for the resolution of problems involving fluid flow around structures. Due to the limitations that traditional methods may have in this context, the VWT ...
Roca Sancho, Jordi (Date of defense: 2013-10-16)
This thesis deals with uncertainty in radar-based precipitation estimation and nowcasting in two ways: its quantification in a probabilistic manner, and its reduction in the precipitation estimates. A straightforward way ...
Fernández Belmonte, Diego (Date of defense: 2009-02-25)
La evaluación preliminar de los resultados de la Reforma Ferroviaria Europea muestra la lentitud de su implementación y la existencia de insuficiencias en el nivel de competencia introducido en el mercado y en la consecución ...
Oller, S. (Sergio), 1955- (Date of defense: 1988-05-31)
Actualmente hay diversas corrientes investigadoras que han profundizado en el estudio del comportamiento mecánico de los materiales, dejando un apreciable cúmulo de experiencias aprovechables. No obstante, se encuentran ...
Díaz Ortíz, Guillermo Fernando (Date of defense: 2014-07-23)
This paper presents a numerical approach for the simulation of reinforced concrete pieces in three dimensions, using embedded discontinuity elements, based on the strong discontinuity approach. In turn, this work is divided ...
Boyet, Auregan (Date of defense: 2024-01-31)
(English) Induced seismicity due to hydraulic stimulation and circulation is a hurdle for the development of Enhanced Geothermal Systems (EGS). The monitored seismicity has occasionally reached magnitudes large enough to ...
Martorell Pol, Pere Antoni (Date of defense: 2024-02-21)
(English) This thesis covers the development of large-scale numerical methods for the simulations of partial differential equations on arbitrarily complex geometries. The target application of this thesis is the structural ...
Aiash, Ahmad (Date of defense: 2023-10-27)
(English) In order to converge towards Vision Zero concept in road safety, traffic crashes need great study and analysis. This thesis is aimed at this goal, applied to the urban and metropolitan environment of Barcelona. ...
Bugeda, G. (Gabriel) (Date of defense: 1990-03-31)
A pesar de que la utilización del método de los elementos finitos está muy extendida, es difícil determinar el nivel de precisión de los resultados obtenidos. Para ello es necesario utilizar alguno de los mallados estimadores ...
Espinoza Román, Héctor Gabriel (Date of defense: 2015-05-08)
The present work is a compilation of the research produced in the field of wave propagation modeling. It contains in-depth analysis of stability, convergence, dispersion and dissipation of spatial, temporal and spatial-temporal ...
Garolera Vinent, Daniel (Date of defense: 2017-09-18)
This thesis describes the extension of the Finite Element Method with zero-thickness interface elements (FEM+z) to 3D, large and complex problems in geomaterials, with special interest in petroleum geomechanics. This general ...
