Fernández-Pedrera Balsells, Marta (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 ...
Arias Araluce, Fausto Arturo (Date of defense: 2017-05-19)
Stroke is a major cause of death and disability in Spain and in the Western world. It is often caused by an accumulation of atherosclerotic plaques on the walls of carotid arteries. Carotid revascularization may be the ...
Dimovska, Sara (Date of defense: 2023-05-26)
(English) Unreinforced masonry buildings (URM), which prevail in many historic and urban centres, can be considered to be significantly vulnerable to seismic actions due to their peculiar constructive and structural features ...
Gutiérrez Martínez, Raquel (Date of defense: 2016-05-03)
Research of new sources of bioenergy is nowadays driving attention to microalgae. Cost-effective biomass harvesting poses a challenge for full-scale microalgae production for biofuels. In the context of wastewater treatment ...
Andreotti, Valeria (Date of defense: 2019-07-12)
In the field of aquaculture, the main microalgae application is animal nutrition, in which they can be used as an unprocessed component, or as dried material for feed preparations. Moreover, microalgae can assimilate the ...
Ortiz Ruiz, Antonio (Date of defense: 2021-12-17)
Microalgae culture is currently receiving considerable attention for its potential in wastewater treatment and production of algal biomass from which high-value bioproducts and bioenergy can be obtained, as well as the ...
Carles Brangarí, Albert (Date of defense: 2017-09-22)
Most of the microorganisms on Earth are found in sophisticated colonies called biofilms. Such microbial communities may proliferate everywhere life can exist as long as nutrients are available and surface attachment is ...
Benedetti, Lorenzo (Date of defense: 2017-05-11)
Strain localization and quasi-brittle failure in frictional-cohesive materials is still an open and challenging problem in computational mechanics. Owing to its complexity and the significant implications on numerous ...
De Vriendt, Kevin (Date of defense: 2021-07-16)
Seawater intrusion presents one of the most unique and ubiquitous groundwater problems in the field of hydrogeology. Its complex boundary conditions coupled with variable density flow results in non-uniform flow which lead ...
