Peñalver Rojo, Domingo (Fecha de defensa: 2019-05-31)
Investments in major transport infrastructure projects involve a significant mobilisation of economic resources both for construction and operation. In these projects, to assess the efficiency of the resources used, ...
Segura Domingo, Jorge (Fecha de defensa: 2020-12-22)
Masonry has been used for millennia to build all sort of constructions. As a result, a significant part of the building stock around the world is made of masonry. In the need of structural assessment, structural analysis ...

Fluid flow, solute transport, and chemical reactions in porous media are highly relevant for multiple applications and in several fields of knowledge. Aquifers are a typical example of porous media, but many others exist, ...
Palau Berastegui, Rosa Maria (Fecha de defensa: 2021-09-23)
Rainfall triggered shallow slides and debris flows constitute a significant hazard that causes substantial economic losses and fatalities worldwide. Regional-scale risk mitigation for these processes is challenging. ...
Alvarado Bueno, Mauricio (Fecha de defensa: 2018-04-23)
Risk associated with landslides of natural or man-made origin depends on the prediction of the post-failure behaviour of the mobilized mass. Numerical models capable of integrating the landslide geometry and its evolution, ...
Salazar Guiral, Guillem (Fecha de defensa: 2019-02-15)
The dark ocean contains about 70% of the ocean’s microbial cells and 60% of its heterotrophic activity, which is mainly fueled by the flux of organic particles produced in the surface ocean and exported to the bathypelagic ...
Elkherbawy, Ahmed Abdelbasset (Fecha de defensa: 2019-10-22)
Lean Construction is regarded as an innovative approach of management for various types of projects in the field of construction. As much as it is currently applied in some countries, its expansion is inevitable, for better ...
Blanca Alcubilla, Gonzalo (Fecha de defensa: 2021-11-26)
Air transport, in 2018, was the means of transport chosen by 8.8 billion people around the world. This is a sector that expected continued passenger growth in the following years, but due to the current effects of the ...
Fernández-Pedrera Balsells, Marta (Fecha de defensa: 2022-05-24)
This thesis analyses the relationships between hydrodynamics (and their forcings) and biological variables in Fangar Bay based on in situ observations, numerical models and satellite data. Fangar Bay is a relatively small, ...
Bělohlav, Vojtěch (Fecha de defensa: 2021-10-20)
Due to the large volume of the processed medium in pilot or industrial cultivation systems, it is difficult to illuminate the entire layer of the culture medium, which results in the formation of dark zones. Due to ...
Toprak, Erdem (Fecha de defensa: 2018-05-02)
The main objective of this thesis is to achieve an improved understanding of the thermo-hydro-mechanical processes and material properties that affect how the gaps and canister) behave during and after installation in the ...
Vila Pérez, Jordi (Fecha de defensa: 2021-02-10)
The aerospace community is challenged as of today for being able to manage accurate overnight computational fluid dynamics (CFD) simulations of compressible flow problems. Well-established CFD solvers based on second-order ...
Salazar González, Fernando (Fecha de defensa: 2017-02-23)
Dam behaviour is difficult to predict with high accuracy. Numerical models for structural calculation solve the equations of continuum mechanics, but are subject to considerable uncertainty as to the characterisation of ...
Codony, David (Fecha de defensa: 2021-03-01)
This PhD thesis focuses on the development of mathematical and computational models for flexoelectricity, a relatively new electromechanical coupling that is present in any dielectric at the micron and sub-micron scales. ...
Soler Sagarra, Joaquim (Fecha de defensa: 2020-07-28)
The study of transport of reacting solute through aquifers is relevant in many engineering fields. Reactive transport (RT) is complex because it consists of two phenomena, solute transport and chemical reactions, both of ...
Marzeddu, Andrea (Fecha de defensa: 2016-04-19)
The aim of this work is the study of laboratory effects on the measurement of wave impact induced loads on rigid maritime structures. A high number of experiments (more then 4000 using regular wave attacks) have been carried ...
Cabané Cañas, Albert (Fecha de defensa: 2023-05-17)
(English) Masonry structures are among the most abundant construction typologies in the world, having been commonly built until the second half of the 20th century. The determination of the mechanical properties of these ...
Puig Damians, Ivan (Fecha de defensa: 2016-07-28)
Soil reinforced retaining wall structures are materiallymore efficientthan competing construction solutions such as gravity and cantilever walls. Nevertheless, the behaviour and interactions between the com ponent materials ...
Comolli, Alessandro (Fecha de defensa: 2018-06-14)
Solute transport in heterogeneous porous media in general exhibits anomalous behaviors, in the sense that it is characterized by features that cannot be explained in terms of traditional models based on the advection-dispersion ...
Gasser i Rubinat, Marc (Fecha de defensa: 2018-11-19)
The Mediterranean Outflow Water (MOW) is a dense (¿>1028.5 kg/m3), saline (38.5 g/kg) ocean stream originated in the evaporative Mediterranean basin flowing westward past Espartel Sill as a fast (>1 m/s) and often unstable ...
