In the Amazon region, few data are available on the impacts caused by the urban settlements found in the proximity of estuaries. In the estuary of the Caeté River, the focus of the present study, the nutrient input is ...
Arrayago Luquin, Itsaso (Data de defensa: 2016-10-17)
This thesis investigates the cross-section and member behaviour of cold-formed stainless steel RHS and SHS elements and proposes an alternative and more efficient design approach. Combined with aesthetic appeal, exceptional ...
Piscal Arévalo, Carlos Mario (Data de defensa: 2018-10-22)
An important percentage of Colombian population is located in medium-to-high seismicity zones (NSR-10, 2010). Therefore, it is important to protect the buildings, principally the highly crowded ones, and those that are ...
Ikumi Montserrat, Tai (Data de defensa: 2017-10-30)
The external sulfate attack (ESA) is a complex degradation process typically compromising the durability of underground foundations, nuclear or industrial waste containments and tunnel linings exposed to sulfate solutions. ...
Ramírez Pérez, Marta (Data de defensa: 2017-06-09)
There is a growing concern for protection and conservation of coastal ecosystems, which require a proper understanding of ecosystem dynamics and the ability to detect and predict changes in the ecosystem state. For this ...
Nogales Arroyo, Alejandro (Data de defensa: 2022-04-11)
The construction industry is one of the industrial sectors with the largest output worldwide and, thus, of great economic interest. In this sector, reinforced concrete plays a significant role since it is one of the most ...
Blanco Rubio, María (Data de defensa: 2018-03-20)
Chemical compounds derived from human activities continuously reach aquatic systems, where they are available to the organisms that inhabit them. Traditionally, environmental risk assessment has been based on the chemical ...
Estruch i Tena, Carles (Data de defensa: 2016-07-13)
We propose to develop, build and validate a new Concept of Bridge composed of Inflatable Beams, Lightweight, Modular and Portable (PVH-LMP) for surface transport vehicles, which uses pressurized air-filled beams made of ...
Casas González, Guillermo (Data de defensa: 2018-10-30)
In this work we study the numerical simulation of particle-laden fluids, with a focus on Newtonian fluids and spherical, rigid particles. We are thus dealing with a multi-phase (more precisely, a multi-component) problem, ...
Irazábal González, Joaquín (Data de defensa: 2017-10-06)
The development of high-speed train lines has increased significantly during the last twenty-five years, leading to more demanding loads in railway infrastructures. Most of these infrastructures were constructed using ...
Crusat Codina, Laura (Data de defensa: 2018-11-05)
The general objective of this thesis is the numerical representation of discrete cracks and their propagation using concepts of Configurational Mechanics, in such a way that their trajectory really corresponds to an energy ...
Wang, Yufei (Data de defensa: 2022-07-11)
Geological Carbon Sequestration (GCS) plays a major role in mitigating the global warming due to the increasing concentration of CO2 in atmosphere. It is important to understand the GCS process to analyze and predict its ...
Hospital Bravo, Raúl (Data de defensa: 2021-07-05)
The design of offshore power stations (for wind, wave or tidal energy generation) requires assessing their environmental impact. In particular, it is of the major importance to predict the impact of the generated subsea ...
Moreno Martínez, Laura (Data de defensa: 2021-09-22)
Viscoelastic fluids are a type of non-Newtonian fluids which are formed by complex internal structures and high-molecular-weight, whose typical examples are the polymer solutions and molten polymers. Also, the viscoleastic ...
Pont Ribas, Arnau (Data de defensa: 2018-02-23)
The solution of the human phonation problem applying computational mechanics is covered by several research branches, such as Computational Fluid Dynamics (CFD), biomechanics or acoustics, among others. In the present ...
Santasusana Isach, Miquel (Data de defensa: 2016-12-01)
This works encompasses a broad review of the basic aspects of the Discrete Element Method for its application to general granular material handling problems with special emphasis on the topics of particle-structure interaction ...
Bertran Oller, Oriol (Data de defensa: 2023-07-11)
(English) Groundwater is now under high stress levels and its quality and quantity arise as one of the most interesting and necessary topics our community should address. This doctoral thesis is focused on the quality of ...
Solaraju Murali, Balakrishnan (Data de defensa: 2023-01-26)
(English) Unfavorable and extreme climate events such as drought and heat stress heavily impacts the agriculture sector and food security globally, and the impact of these climate hazards is expected to increase over the ...
Martí Donati, Alejandro (Data de defensa: 2017-07-14)
Explosive volcanic eruptions can eject large quantities of particulate matter that, along with other aerosol droplets and trace gases, are carried upwards into the atmosphere by the buoyant eruption column and then dispersed ...
