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 ...

Se ha llevado a cabo:<br/><br/>A) Un estudio de las propiedades básicas del suelo no saturado (tipo limo) a escala microestructural, incluyendo esqueleto sólido, fase liquida y fase gaseosa. <br/><br/>B) Elaboración de un ...
Giné Garriga, Ricard (Date of defense: 2015-11-21)
Water and sanitation improvements together with good hygiene (WaSH) have well-known positive impacts on human development and poverty alleviation. However, universal access to safe drinking water and basic sanitation remains ...
Bonilla de Toro, Jesús (Date of defense: 2019-12-17)
This thesis covers the development of monotonicity preserving finite element methods for hyperbolic problems. In particular, scalar convection-diffusion and Euler equations are used as model problems for the discussion in ...
Huang, Dong (Date of defense: 2023-12-19)
(English) As a crucial node of maritime transportation, seaports carry more than 90% of global trade. Considering the complexity of a port system, even slight improvement at strategical and operational decision levels will ...
Sciandra, Dario (Date of defense: 2024-02-09)
(English) Geological Carbon Storage (GCS) holds immense promise for mitigating atmospheric CO2 emissions, making the sealing capacity of caprocks pivotal as storage scales up. Despite excellent sealing capacities observed ...
Lin Ye, Jue (Date of defense: 2018-05-22)
Wave-storms are the responsible of the main changes in the Coast. Their detailed characterization results in a better design of any marine structure. The most common approach to describe wave-storms is to simplify the event ...
