Corrales Ribas, Xavier (Date of defense: 2019-03-21)
Firstly, I reviewed modelling approaches that were used to assess the impact of invasive alien species (IAS) in aquatic ecosystems. According to the review, multispecies/ecosystem mechanistic models dominated the applications, ...
Pérez Madrigal, Domingo (Date of defense: 2018-06-20)
The use of bituminous material milled from the pavement (known as Reclaimed Asphalt Pavement, or RAP) in the manufacture of recycled bituminous mixtures is growing day by day due to the economic and environmental benefits ...
López Montero, Teresa (Date of defense: 2018-06-19)
Asphalt mixtures cracking is one of the most common deterioration mechanisms in flexible pavements. This phenomenon is due to both the application of loads and the degradation of the material as a result of its exposure ...
Mora Ortiz, René Sebastián (Date of defense: 2016-03-03)
The microstructure, understood as the distribution of pore sizes and their connectivity, is an important factor that affects the mechanical behaviour and the hydraulic properties of compacted soils with fine fraction (silts ...
Villarraga Díaz, Claudia Juliana (Date of defense: 2018-02-28)
The environmental conditions may play a relevant role in the stability of rock slopes. In fact, weathering can contribute to the reduction of strength of the material, while atmospheric actions may increase internal stresses ...
Marín Beltrán, Isabel (Date of defense: 2017-07-21)
The Mediterranean Sea is an oligotrophic basin, while the atmosphere above is affected by continuous emissions of anthropogenic aerosols and episodic Saharan dust events. These atmospheric inputs finally deposit (as wet ...
Titscher, Thomas (Date of defense: 2019-09-27)
Concrete is a complex material and can be modeled on various spatial and temporal scales. While simulations on coarse scales are practical for engineering applications, a deeper understanding of the material is gained on ...
Quaranta, Giacomo (Date of defense: 2019-09-02)
Numerical simulation, the use of computers to run a program which implements a mathematical model for a physical system, is an important part of today technological world. It is required in many scientific and engineering ...
Yubero de Mateo, Maria Teresa (Date of defense: 2021-07-22)
The urban tunneling may generate significant problems. One of the main concerns is the unavoidable ground movements generated; before, during and after the tunneling operations. In this context, the objective of this Thesis ...
Fernández González, Mario, 1970- (Date of defense: 2019-07-25)
This PhD thesis aims to analyse and verify the tense and intense relation that is established between the architecture, civil engineering and art worlds. Such analysis is conducted not only in a formal manner, but also at ...
Salas Olivares, Héctor Manuel (Date of defense: 2021-09-14)
(English) he textile industry consumes a large volume of water in various activities and is an importan! wastewater generator. Colorless dyes that emit fluorescence when exposed to UV light are used in the optical whitening ...
Roca i Sans, Josep-Miquel (Date of defense: 2020-11-12)
This thesis aims to develop simple models that allow evaluating the relevance of the principal parameters that condition the energy flows in the ocean-atmosphere system, and how changes in these parameters impact the climate ...
Muñoz Liesa, Joan (Date of defense: 2022-07-20)
(English) Cities are great resource consumers and largely contribute to anthropogenic environmental impacts, urgently requiring a decarbonization plan. Urban agriculture lies on industrial ecology principles; waste resources ...
Bortolini, Rafaela (Date of defense: 2019-02-28)
The performance of existing buildings is receiving increased concern due to the need to renovate the aging building stock and provide better quality of life for end users. The conservation state of buildings and the indoor ...
Montemayor, Erica Yvonne (Date of defense: 2022-11-24)
(English) Agriculture not only contributes to more than a quarter of all global greenhouse gas emissions but is also the number one anthropogenic source of nitrogen emissions and a danger to nearly half of threatened ...
Reis, Jonatha Oliveira de Matos (Date of defense: 2020-12-29)
A significant part of the current research efforts in computational mechanics is focused on analyzing and handling large amounts of data, exploring high dimensional parametric spaces and providing answers to increasingly ...
Otegi Aldai, Karmele (Date of defense: 2019-06-10)
Electric Arc Furnace Slag (EAFS) is the by-product generated in the steel making process in electric arc furnaces. According to the European slag association, EUROSLAG, 18,4Mt of steel slag have been reported, of which ...
Cárdenas Díaz, Octavio Enrique (Date of defense: 2018-10-19)
This thesis studies the hydro-mechanical behaviour of a compacted clayey sand under generalised stress state. The study, which is mainly experimental, focuses on the analysis of the shear strength at different hydraulic ...
Castellón López, Javier (Date of defense: 2020-02-18)
Soil behavior in the range of small strains should be considered in the analysis of geotechnical problems when sensitive elements are affected, which is very common in urban environments. However, some of the tests that ...
Martínez Estévez, Ariadna (Date of defense: 2020-06-29)
In order to cope with the serious and urgent problem of global warming, it is imperative to reduce the impact of CO2 emissions in the atmosphere. One of the alternatives proposed involves the injection of the CO2 in deep ...
