de Vreese, Steffen (Date of defense: 2021-06-17)
While marine, anthropogenic noise pollution is a scientific and societal matter of concern, there is limited knowledge on how sea animals, particularly cetaceans, perceive their environment through sounds. Toothed whales, ...
Yerro Colom, Alba (Date of defense: 2015-11-10)
Landslides and slope instabilities represent one of the most important problems in geotechnics causing significant damages around the world every year. Understanding the mechanics of the whole process is of particular ...
Ferrer Ferré, Àlex (Date of defense: 2017-05-26)
The present dissertation aims at addressing multiscale topology optimization problems. For this purpose, the concept of topology derivative in conjunction with the computational homogenization method is considered. In ...
Wang, Jingjing (Date of defense: 2021-07-23)
Reactive transport modeling is a methodological tool to study the coupled physical, chemical and biological processes in Earth system. It is complex not only because of the nature of the equations, but also because of the ...
Zaghi, Stefano (Date of defense: 2019-01-21)
The improvements in terms of computational power provides the capability to analyze with more detail the materials behavior. On one hand, going deeper in the materials to study an increasingly smaller dimension and capture ...
Monteiro, Marcela Cunha (Date of defense: 2017-04-04)
In the Amazon region, few data are available on the impacts caused by the urban settlements found in the proximity of estuaries. In the estuary of the Caeté River, the focus of the present study, the nutrient input is ...
Arrayago Luquin, Itsaso (Date of defense: 2016-10-17)
This thesis investigates the cross-section and member behaviour of cold-formed stainless steel RHS and SHS elements and proposes an alternative and more efficient design approach. Combined with aesthetic appeal, exceptional ...
Piscal Arévalo, Carlos Mario (Date of defense: 2018-10-22)
An important percentage of Colombian population is located in medium-to-high seismicity zones (NSR-10, 2010). Therefore, it is important to protect the buildings, principally the highly crowded ones, and those that are ...
Ikumi Montserrat, Tai (Date of defense: 2017-10-30)
The external sulfate attack (ESA) is a complex degradation process typically compromising the durability of underground foundations, nuclear or industrial waste containments and tunnel linings exposed to sulfate solutions. ...
Ramírez Pérez, Marta (Date of defense: 2017-06-09)
There is a growing concern for protection and conservation of coastal ecosystems, which require a proper understanding of ecosystem dynamics and the ability to detect and predict changes in the ecosystem state. For this ...
Nogales Arroyo, Alejandro (Date of defense: 2022-04-11)
The construction industry is one of the industrial sectors with the largest output worldwide and, thus, of great economic interest. In this sector, reinforced concrete plays a significant role since it is one of the most ...
Blanco Rubio, María (Date of defense: 2018-03-20)
Chemical compounds derived from human activities continuously reach aquatic systems, where they are available to the organisms that inhabit them. Traditionally, environmental risk assessment has been based on the chemical ...
Estruch i Tena, Carles (Date of defense: 2016-07-13)
We propose to develop, build and validate a new Concept of Bridge composed of Inflatable Beams, Lightweight, Modular and Portable (PVH-LMP) for surface transport vehicles, which uses pressurized air-filled beams made of ...
Casas González, Guillermo (Date of defense: 2018-10-30)
In this work we study the numerical simulation of particle-laden fluids, with a focus on Newtonian fluids and spherical, rigid particles. We are thus dealing with a multi-phase (more precisely, a multi-component) problem, ...
Irazábal González, Joaquín (Date of defense: 2017-10-06)
The development of high-speed train lines has increased significantly during the last twenty-five years, leading to more demanding loads in railway infrastructures. Most of these infrastructures were constructed using ...
Crusat Codina, Laura (Date of defense: 2018-11-05)
The general objective of this thesis is the numerical representation of discrete cracks and their propagation using concepts of Configurational Mechanics, in such a way that their trajectory really corresponds to an energy ...
Wang, Yufei (Date of defense: 2022-07-11)
Geological Carbon Sequestration (GCS) plays a major role in mitigating the global warming due to the increasing concentration of CO2 in atmosphere. It is important to understand the GCS process to analyze and predict its ...
Hospital Bravo, Raúl (Date of defense: 2021-07-05)
The design of offshore power stations (for wind, wave or tidal energy generation) requires assessing their environmental impact. In particular, it is of the major importance to predict the impact of the generated subsea ...
Moreno Martínez, Laura (Date of defense: 2021-09-22)
Viscoelastic fluids are a type of non-Newtonian fluids which are formed by complex internal structures and high-molecular-weight, whose typical examples are the polymer solutions and molten polymers. Also, the viscoleastic ...
Pont Ribas, Arnau (Date of defense: 2018-02-23)
The solution of the human phonation problem applying computational mechanics is covered by several research branches, such as Computational Fluid Dynamics (CFD), biomechanics or acoustics, among others. In the present ...
