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 ...
Larion, Ygee (Date of defense: 2022-02-01)
In a large number of geo-environmental applications, it is essential to model coupled processes that depend on several design parameters such as material properties and geometrical features. Thermo-hydro-mechanical (THM) ...
Puig Montellà, Eduard (Date of defense: 2019-07-16)
Numerical simulations at the pore scale are a way to study the behavior of multiphase flows encountered in many natural processes and industrial applications. In this work, liquid morphology and capillary action are examined ...
Stamatopoulos, Georgios (Date of defense: 2023-07-07)
(English) This thesis records the evolution of the container throughput dynamics of the European port system from 2001-2020, analyses the dynamics of the European container port hierarchy with methodologies that have not ...
Jarauta Arabi, Àlex (Date of defense: 2016-03-30)
Fuel cells are promising alternatives to conventional energy conversion devices. Cells fueled with hydrogen are environmentally friendly and their effciency is up to 3 times higher than that of high-temperature combustion ...
Canelles Garcia, Arnau (Date of defense: 2022-07-13)
(English) Managed Aquifer Recharge (MAR) is a key strategy to increase freshwater resources in many regions facing water scarcity. The success of a MAR facility implies both technical (water quality and quantity as main ...
Rahbaralam, Maryam (Date of defense: 2018-02-23)
Random walk particle tracking methods are a computationally efficient family of methods to solve reactive transport problems. While the number of particles in most realistic applications is in the order of 10^6 - 10^9, the ...
Fabra Ruiz, Arnau (Date of defense: 2023-10-16)
(English) This thesis presents novel approaches and computational methods for solving wave propagation problems in acoustics and linear elasticity. Stabilized finite element methods in the context of the variational ...
Vendrell Miguel, Lluís (Date of defense: 2017-11-10)
This thesis aims to test the ability of a non-hydrostatic multiscale mineral dust model to reproduce the physical processes associated with the dust cycle at meteorological scales ranging from synoptic to mesoscale (~100-1 ...
Matas Casado, Gerard (Date of defense: 2020-11-04)
The fragmentation process in rockfalls is a complex phenomenon that is not well understood and only a few rockfall simulation models consider it explicitly. Fragmentation significantly affects the evaluation of the hazard ...
Rodríguez-Ros, Pablo (Date of defense: 2020-07-16)
Isoprene (C5H8) is the most widely emitted biogenic volatile organic carbon (BVOC). It is produced in the biosphere both on land and in the ocean, and in the atmosphere it acts as a precursor of secondary organic aerosols. ...
Quattrocchi, Federico (Date of defense: 2017-10-24)
The understanding of the driving forces involved in the abundance fluctuation of fish populations is an important requirement for conservation and management, especially in the context of environmental changes. In the North ...
Song, Fei (Date of defense: 2021-06-28)
Representing the time-dependent plastic behaviour of geomaterials is a critical issue in the correct application of tunnelling design techniques such as the convergence-confinement method or numerical modelling. Furthermore, ...
Roigé Montornés, Núria (Date of defense: 2020-07-15)
This Doctoral Thesis addresses aspects of interest for hydraulic infrastructure managers, such as investment decision support tools, in order to provide both decision support and the justification tools which are required ...
