Montemayor, Erica Yvonne (Data de defensa: 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 (Data de defensa: 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 (Data de defensa: 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 (Data de defensa: 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 (Data de defensa: 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 (Data de defensa: 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 ...
Quirós Collazos, Lucía (Data de defensa: 2022-06-27)
The present PhD thesis is focused on the paleoclimatic reconstruction of the Pacific Ocean equatorial upwelling conditions, east of the Galapagos Islands, over the last 160.000 years. This region is of great interest to ...
Duarte Gómez, Noemí (Data de defensa: 2023-05-12)
(English) Performance-based design (PBD) is a philosophy for structural design that puts emphasis on the realistic estimation of the structural behaviour and its relationship with the objectives of the final user, or ...
Herrera Mesén, Carlos Manuel (Data de defensa: 2018-03-16)
Sprayed cementitious materials are widely used in the construction industry, from buildings to infrastructure. The process of construction consists of spraying a concrete mix that consolidates once it reaches the substrate. ...
Jiménez Pacheco, Juan Carlos (Data de defensa: 2016-12-16)
Currently, there are very few programs specialized in seismic analysis of unreinforced masonry buildings. Most studies have focused on the seismic behavior of the walls or (in a 3D level) have not integrated the flexibility ...
Rodríguez Rey, Daniel (Data de defensa: 2022-03-21)
Persistent high levels of NO2 have severe health effects on population. These are often found in large urban conurbations with high vehicle densities. In Barcelona, with one of the highest vehicle densities in Europe, the ...
Gonzàlez Corominas, Andreu (Data de defensa: 2016-06-21)
In recent decades, the use of High Performance Concrete (HPC) has grown vastly, being used in multiple applications with high requirements. However, the use of recycled aggregates (RA) has been mostly limited to conventional ...
Najdi, Abdallah (Data de defensa: 2023-06-20)
(English) The thesis presents part of an ongoing nvestigation on the Thermo-Hydro-Mechanical (THM) behaviour and cracking of deformable unsaturated soils undergoing cycles of drying and wetting. An experimental approach ...
Gasparini, Andrea (Data de defensa: 2021-03-04)
CO2 geological storage is considered one of the options technologically viable in order to decrease the industrial emissions of this gas species that strongly contribute to the greenhouse effect in the atmosphere (IPCC, ...
Liaudat, Joaquín (Data de defensa: 2018-06-15)
This thesis aims at deepening in the understanding of the mechanisms by which the stress state affects the development of concrete expansions and cracking due to the Alkali-Silica Reaction (ASR). With this purpose, a ...
Fraccica, Alessandro (Data de defensa: 2019-12-09)
The thesis is aimed at characterising the multi-scale and hydro-mechanical behaviour of lightly compacted silty sand penetrated by a turf-grass (Cynodon Dactilon). The study will allow better assessing the impact of ...
Santín Muriel, Andreu (Data de defensa: 2022-01-24)
Sponge assemblages dominate several distinctive, hard-bottom environments, being one of the most important structural organisms at several locations around the world. Although the Mediterranean sponge fauna is among the ...
Gürkan, Ceren (Data de defensa: 2018-11-22)
This thesis proposes a new numerical technique: the eXtended Hybridizable Discontinuous Galerkin (X-HDG) Method, to efficiently solve problems including moving boundaries and interfaces. It aims to outperform available ...
Mena Andrade, Ramiro Francisco (Data de defensa: 2021-01-15)
Computer simulation is acknowledged as the third branch of Science. From the seminal work of Turner et al. (1956) [on Finite Elements, impressive improvements have been made in terms of software and hardware, so that, ...
