Valdés Alonzo, Gabriel Rolando (Date of defense: 2022-06-03)
Identifying the constitutive relations of materials is an essential task to understand their behavior. Classical methods like testing can be effective in understanding these relationships, but introducing models can lead ...
Sanuy Vázquez, Marc (Date of defense: 2019-11-05)
The impact of coastal storms is one of the costliest forms of natural disaster, as it affects a particularly valuable fringe both from the socioeconomic and ecologic perspectives. In addition, storm-induced erosion and ...
Tellez Alvarez, Jackson David (Date of defense: 2019-05-10)
This Doctoral Thesis dissertation concerns two main research topic: the analysis of the flow velocity pattern in the nearness of a grate inlet through Surface Flow Image Velocimetry (SFIV) technique and the study of overflow ...
Seco, Raquel Irene (Date of defense: 2014-12-05)
The accumulation of sediments in combined sewer systems may give rise to significant quality problems, which sometimes are overlooked. Solids deposited in the network may lead to more frequent overflows into natural waters, ...
Mataix Ferrándiz, Vicente (Date of defense: 2020-09-03)
The doctoral thesis "Innovative mathematical and numerical models for studying the deformation of shells during industrial forming processes with the Finite Element Method" aims to contribute to the development of finite ...
Martínez Gomariz, Eduardo (Date of defense: 2016-11-04)
In this research work, an analysis is first undertaken on the hazard regarding people exposed to floods in urban areas. Several experiments with people were carried out in order to determine the stability limit to pedestrians, ...
Jiménez Fernández de Palencia, Alejandro (Date of defense: 2010-05-17)
El primer objetivo de esta tesis es la identificación y análisis de aspectos clave para la gobernanza de los servicios de agua rural en países que adolecen de bajos niveles de cobertura, altos índices de pobreza, se ...
Castro-Alcalá, Eduardo (Date of defense: 2019-05-30)
Tracer visualization in the laboratory at high spatial and temporal resolution can help advance the study of mixing processes. However, grain borders, fluctuations in lighting and non-uniform brightness contribute to produce ...
Colomés Gené, Oriol (Date of defense: 2016-03-31)
In this thesis we have developed a path towards large scale Finite Element simulations of turbulent incompressible flows. We have assessed the performance of residual-based variational multiscale (VMS) methods for the ...
Miranda Neiva, Eric (Date of defense: 2020-10-07)
This thesis addresses large-scale numerical simulations of partial differential equations posed on evolving geometries. Our target application is the simulation of metal additive manufacturing (or 3D printing) with powder-bed ...
Oliver Serra, Albert (Date of defense: 2015-11-13)
Air pollution is an important topic with a great social impact; it is related with public health, environment and ecology, and climate change. Scientists have developed several models in the last thirty years, and regional ...
Trapote Barreira, César (Date of defense: 2015-12-16)
This thesis aims to dissert about air transport network design taking into consideration the current needs about efficiency in a very competitive industry. The main focus for this work is the airline's point of view and ...
Cabrera Vélez, Esteban Marcelo (Date of defense: 2023-02-16)
(English) In post-seismic scenarios, the rapid and safe evaluation of structural damage is essential to develop an effective response during the recovery, rehabilitation and reconstruction stages. The development of new ...
Barbat Vlad, Gabriel (Date of defense: 2021-02-11)
The numerical modelling of fracture has been an active topic of research for over five decades. Most of the approaches employed rely on the use of the Finite Element Method, which has shown to be an effective and cost-efficient ...
De Gaspari, Francesca (Date of defense: 2015-04-30)
Geochemical and reactive transport modelling are essential tools in hydrogeology. They help to identify and assess geochemical processes occurring in applications such as groundwater contamination, water-rock interactions ...
Nasika, Christina (Date of defense: 2022-06-28)
The latest monitoring and asset management technologies for large infrastructures involve digital representations that integrate information and physical models, exist in parallel to the real-life structures, and are ...
Caro Camargo, Carlos Andrés (Date of defense: 2016-01-25)
Distributed hydrological modeling occurs as a historical consequence of the different developments and advances in conceptual hydrology, first, through deepening and adaptation of hydrology through aggregated methods, and ...
Aragón Hernández, José Luis (Date of defense: 2013-07-02)
El crecimiento continuo de las ciudades, o la ocurrencia de un evento extraordinario de lluvia, en muchas ocasiones sobrepasa las medidas de diseño de algunos de los elementos del drenaje urbano (principalmente elementos ...
Sala Sanmartí, Marcel (Date of defense: 2019-10-29)
Freeway traffic management is necessary to improve capacity and reduce congestion, especially in metropolitan freeways where the rush period lasts several hours per day. Traffic congestion implies delays and an increase ...
Khadivipanah, Peiman (Date of defense: 2022-02-03)
The main objective of this thesis is to describe and implement a rate-dependent (viscoplastic) constitutive equations for copper based canister using a single internal state variable and use it for modelling disposal schemes ...
