The main objective of this thesis is the study of a marine sediment core located in front of French Guiana (7°48’75’’N i 53°0’80’’W -1233m bsl and 39m length), in northern South America. The last 415,000 years were studied ...
Orúe-Echevarría Iglesias, Dorleta (Date of defense: 2019-11-04)
The Southwest Atlantic Ocean is a key component of the global climate system. It holds the Confluence of the Brazil and Malvinas Currents (BMC), one of the highest frontal systems of the world ocean. The BMC is the encounter ...
Alavi, Hamidreza (Date of defense: 2022-10-11)
A Decision Support System (DSS) can help facility managers to improve building performance, occupants’ comfort, and energy efficiency during the Operation and Maintenance (O&M) phase. These DSSs are normally data-intensive ...
Fernández Tejedor, Margarita (Date of defense: 2023-12-18)
(English) The increase in the production of marine bivalves targets the sustainable development of aquaculture to improve global food and nutrition security. Bivalve aquaculture is currently facing challenges and threats ...
Pieralisi, Ricardo (Date of defense: 2016-04-13)
Pervious concrete is a special material with high permeability usually obtained by reducing the amount of fine aggregates in the composition of concrete. The properties of pervious concrete not only depend on its composition ...
Roig Planasdemunt, Maria (Date of defense: 2016-06-27)
The main objective of this thesis is to characterize hydrological processes in a Mediterranean mountain catchment, by combining distributed hydrological measurements and environmental tracers in order to improve the ...
Martínez Pérez, Laura (Date of defense: 2020-07-09)
Seawater intrusion (SWI) causes not only salinization of coastal aquifers, but also a reduction submarine groundwater discharge (SGD) and nutrient fluxes to marine ecosystems. We have developed a small scale experimental ...
Plans Pujolràs, Albert (Date of defense: 2017-09-26)
The concrete-steel composite slabs show a complex structural characterization due to the different behaviours at the two materials. The materials are exposed to different deformations, large deflections and complex stresses ...
Rodero García, Carlos (Date of defense: 2023-05-29)
(English) Light attenuation is a critical factor in aquatic ecosystems for many physical and biological processes. Water transparency plays an essential role in understanding the variations of the ecological environment ...
Morey Gual, Lluís (Date of defense: 2023-11-17)
(English) The exponential growth of world population is leading to a high demand of food products and, consequently, to the development of intensive agricultural and livestock systems. In this sense, synthetic fertilizers ...
Ballesteros Martínez, Caridad (Date of defense: 2017-07-18)
Coastal zones concentrate an elevated number of values both natural and socio-economic, making them very vulnerable to the potential effects of natural hazards. Therefore, effective risk management requires a holistic ...
Paipuri, Mahendra (Date of defense: 2018-03-21)
This thesis proposes a coupled continuous and hybridizable discontinuous Galerkin formulation to solve conjugate heat transfer problems. This model is then used to find the thermal response of Glass Fiber Reinforced Polymer ...
Badia Rodriguez, Hugo (Date of defense: 2016-12-19)
This thesis discusses which transit network structure is the best option to serve urban mobility. As a consequence of the evolution of urban form, cities have undergone a dispersion process of their activities. This fact ...
Lanko, Iryna (Date of defense: 2022-01-27)
Anaerobic digestion (AD) is currently spread all over the world for sewage sludge stabilisation, volume reduction and green energy production. Its implementation contributes to turn a wastewater treatment plant (WWTP) into ...
Tsiolakis, Vasileios (Date of defense: 2020-01-31)
The present thesis explores the viability of the proper generalised decomposition (PGD) as a tool for parametric studies in a daily industrial environment. Starting from the equations modelling incompressible flows, the ...
Weber, Rodrigo Carreira (Date of defense: 2019-12-13)
This thesis analyzes the hydro-mechanical behavior under a generalized stress state of a compacted mixture of sand (30%) and clayey (70%) at a low density. The experimental study focuses on the analysis of shear strength ...
Alvarado de Menéndez, Clara Elena (Date of defense: 2017-05-18)
Rockfill is a coarse material widely used in geotechnical works such as earth-fill dams (shoulders and toe drains), as well as in embankments and well-graded quarry materials for railway infrastructures. These structures ...
Lu, Xufei (Date of defense: 2022-07-15)
The objectives of this thesis are (i) to understand the thermal, metallurgical and mechanical behavior during AM, (ii) to shed light on the generation of residual stresses and the stress-induced deformations and cracks, ...
