Rivero, Matias Ignacio (Date of defense: 2018-04-27)
In the field of nonlinear computational solid mechanics, contact problems deal with the deformation of separate bodies which interact when they come in touch. Usually, these problems are formulated as constrained minimization ...
Ziaei-Rad, Vahid (Date of defense: 2016-05-02)
The phase field method has proven to be an important tool in computational fracture mechanics in that it does not require complicated crack tracking and is able to predict crack nucleation and branching. However, the ...
Abdollahi, Amir (Date of defense: 2012-10-18)
The unique electro-mechanical coupling properties of ferroelectrics make them ideal materials for use in micro-devices as sensors, actuators and transducers. Nevertheless, because of the intrinsic brittleness of ferroelectrics, ...
Mujal Colilles, Anna (Date of defense: 2013-05-13)
Particle Image Velocimetry (PIV) is one of the most used experimental techniques in fluid mechanics to obtain the velocity field of a flow. One of its most celebrated characteristics is that it does not have interference ...
Hernández Navarro, Olver Olfrey (Date of defense: 2018-02-22)
Rainfall nowcasting based on the extrapolation of most recent radar rainfall fields usually shows better skill than NWP models for short lead times, since it benefits from observations of the initial rainfall state. In ...
Encinas Bachiller, Andrés Marcos (Date of defense: 2001-10-01)
En este trabajo se ha desarrollado un cálculo vectorial sobre estructuras discretas, análogo al de los modelos continuos. Para ello se ha considerado como espacio subyacente un multigrafo finito o variedad discreta y se ...
Vaezi Anzeha, Iman (Date of defense: 2023-12-21)
(English) This doctoral thesis investigates the causes that induce (micro)seismicity as a result of hydraulic stimulation in fractured low-permeability rock. Understanding such phenomenon is of paramount importance to ...
López Sánchez, Ángel (Date of defense: 2010-11-16)
The work’s development is made by scientific method stages: aims statement, hypothesis establishment and work method to check hypothesis. Conclusions are given at the end. It is supported by: a) Bibliographical review, ...
Rocas Alonso, Marc (Date of defense: 2021-07-23)
The automotive industry is constantly involved in the development of new methodologies and projects with the aim of reducing costs. During the vehicle design process, one of the most significant cost arises from building ...
Wu, Haiqing (Date of defense: 2023-07-28)
(English) Understanding the triggering mechanisms of induced seismicity remains one of the most critical challenges in geo-energy applications. This Thesis aims at assessing (1) fault stability and induced seismicity ...
Gomis Sánchez, Jordi (Date of defense: 2012-07-10)
Throughout history, man has had the need to communicate through drawings, and drawing has evolved as another language. The technical aspect of drawing has sought to represent objects as faithfully as possible, both insofar ...
Camacho Navarro, Jhonatan (Date of defense: 2019-07-15)
This thesis presents the results of applying a statistical hybrid approach for structural health monitoring using piezo actuating signals. Where, by combining statistical processing based on Principal Component Analysis ...
Olm Serra, Marc (Date of defense: 2019-02-18)
The main object of study of this thesis is the development of scalable and robust solvers based on domain decomposition (DD) methods for the linear systems arising from the finite element (FE) discretization of transient ...
Larriva Villarreal, Hernán Javier (Date of defense: 2023-11-06)
(English) Turbidity currents in reservoirs are of strong scientific interest because they can be responsible for the contribution of large amounts of fine sediments that can cause early sediment filling. The case study ...
Uggetti, Enrica (Date of defense: 2011-09-30)
During the last years, the implementation of new Wastewater Treatment Plants has lead to a significant increase of sludge production. As a response, sludge valorisation in agriculture is the preferred option nowadays, ...
Cante Terán, Juan Carlos (Date of defense: 1995-07-19)
En esta tesis se presenta un modelo numérico para simular la fase de compactación de pulvimateriales y su implementación en ordenadores de cálculo paralelo, con el ánimo de facilitar y mejorar el diseño de los procesos de ...
Boix Cots, David (Date of defense: 2023-12-15)
(English) This doctoral thesis addresses one of the most significant challenges facing the Spanish administration: the efficient selection and management of public investments. To achieve this goal, the 'Public Investment ...
Germano, Nicola (Date of defense: 2021-12-14)
This thesis aims to propose and validate an innovative, fully open-source framework capable of performing multiscale analysis for the assessment of local wind flows within the urban fabric. Each part of the framework is ...
Martí Cardona, Belén (Date of defense: 2014-05-14)
The Doñana wetlands, in Southwest Spain, undergo yearly cycles of inundation in fall and drying out during the spring season. As any wetland ecosystem, Doñana depends critically on its water resources. Important monitoring ...
Planas Badenas, Ramon (Date of defense: 2013-11-25)
Magnetohydrodynamics (MHD) is the physics branch that studies electrically conducting fluids under external magnetic fields. This thesis deals with the numerical approximation using stabilized finite element methods of two ...
