Gasparini, Andrea (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 (Date of defense: 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, ...
Aidarov, Stanislav (Date of defense: 2022-05-06)
Fibre reinforced concrete (FRC) has proven to be a suitable material for statically indeterminate elements. The FRC column-supported flat slabs with partial or even total substitution of reinforcing steel bars constructed ...
Carlesso, Débora Martinello (Date of defense: 2020-03-06)
Fibre reinforced concrete (FRC) is recognized as suitable material for structural applications. The number of national codes that have approved it is an evidence. Structures where FRC is generally used can be subjected to ...
Ruiz-Orejón, Luis F. (Date of defense: 2018-07-02)
Plastics are currently one of the most widely distributed litter in marine ecosystems worldwide. The floating fraction of these debris are estimated to represent about 1% of the plastics that enter into the marine environment ...
Tello Guerra, Alexis (Date of defense: 2020-07-10)
The standard Fluid Structure Interaction coupling (velocity--pressure/displacement) is compared against two novel types of coupling, a Two Field coupling (velocity--pressure/displacement--pressure) and a Three Field coupling ...
Janeras Casanova, Marc (Date of defense: 2023-10-23)
(English) In the Montserrat Mountain, high hazard of rockfall and high human exposure by visitors to both Monastery and Natural Park converge. It is a relevant geological risk difficult to mitigate since it is necessary ...
Rausis, Kwon (Date of defense: 2020-11-03)
This work discloses new insights into the formation and evolution of Mg -carbonates as well as carbonation processes of Mg-rich oxides and silicates with the aim of providing a safe and permanent anthropogenic CO2 storage, ...
Poliotti, Mauro (Date of defense: 2020-11-04)
Modern guidelines for design and assessment of reinforced concrete structures under seismic and other extreme loads require nonlinear analysis. The complex structural response can be obtained by means of three-dimensional ...
Cornejo Velázquez, Alejandro (Date of defense: 2020-12-21)
It is well known that in civil engineering structures are designed so that they remain,whenever possible, in an elastic regime and with their mechanical properties intact. The truth isthat in reality there are uncertainties ...
Gonzalez‐Blanco, Laura (Date of defense: 2017-05-31)
Deep geological disposal remains the preferred option at present for the management of long-living and heat-emitting radioactive waste, which consists of confining the waste during a very long period (several hundreds of ...
Labarre, Aurélie (Date of defense: 2020-11-26)
In the vast network of the ocean, microbes are abundant and unevenly distributed. As an important microbial component, the protists play a key role in global biogeochemical cycles and contribute to the recycling of nutrients ...
Dávila Ordóñez, Maria Gabriela (Date of defense: 2015-11-06)
A test site for CO2 geological storage is situated in Hontomín (Burgos, northern Spain) with a reservoir rock that is mainly composed of limestone. The reservoir rock is a deep saline aquifer, which contains a NaCl- and ...
Shen, Yanfei (Date of defense: 2019-12-02)
In AISC 360-16, the Direct Analysis Method (DM) has been set as the primary method for the stability design of frames. DM, considering initial global sway imperfection, is essentially Geometrically Non-linear Analysis (GNA) ...
García Alcaraz, María del Mar (Date of defense: 2016-03-04)
This thesis promotes an efficient use of shallow geothermal energy by means of an integrated management system to organize its exploitation. Shallow geothermal energy is a renewable resource based on thermal energy exchange ...
Torres Serra, Joel (Date of defense: 2021-02-26)
In the packaging industry, a wide range of powders and bulk solids are handled in bagging equipment using different bulk feeding techniques. Quality of the packaging is critically affected by feeder performance, which is ...
