Approximation of phase-field models with meshfree methods: exploring biomembrane dynamics
Las biomembranas constituyen la estructura de separación fundamental en las celulas animales, y son importantes en el diseño de sistemas bioinspirados. Su simulación presenta desafíos, especialmente cuando ésta implica ...
Un modelo de discontinuidades fuertes para la simulación numérica de la fractura en compresión, de piezas de hormigón armado en tres dimensiones
This paper presents a numerical approach for the simulation of reinforced concrete pieces in three dimensions, using embedded discontinuity elements, based on the strong discontinuity approach. In turn, this work is divided ...
Strategies for improving import yard performance at container marine terminals
The process of containerization and its continuous development involves changes and technological innovations in containerships and maritime container terminals. In the current era of "gigantism", despite existing fleet ...
Effects of climate change on wave climate and consequent coastal impacts : application to the Catalan coast (NW Mediterranean Sea)
Climate change is a hot research topic due to the consequent impacts on our environment in the near future. The last report of the International Panel on Climate Change' the leading international body for assessment of ...
Spaceborne SAR imagery for monitoring the inundation in the Doñana wetlands
The Doñana wetlands, in Southwest Spain, undergo yearly cycles of inundation in fall and drying out during the spring season. As any wetland ecosystem, Doñana depends critically on its water resources. Important monitoring ...
Sediment-water interaction in a water reservoir affected by acid mine drainage : experimental and modeling
The discharge of acid mine drainage into a water reservoir may seriously affect the water quality. In this setting, sediment is commonly thought to act as a sink for pollutants. However, redox oscillations in the bottom ...
Tractament de la incertesa en estimació i previsió de pluja amb radars meteorològics
This thesis deals with uncertainty in radar-based precipitation estimation and nowcasting in two ways: its quantification in a probabilistic manner, and its reduction in the precipitation estimates. A straightforward way ...
Stabilized finite element formulations for solving incompressible magnetohydrodynamics
Magnetohydrodynamics (MHD) is the physics branch that studies electrically conducting fluids under external magnetic fields. This thesis deals with the numerical approximation using stabilized finite element methods of two ...
Efficient models for building acoustics : combining deterministic and statistical methods
Modelling vibroacoustic problems in the field of building design is a challenging problem due to the large size of the domains and the wide frequency range required by regulations. Standard numerical techniques, for instance ...
Design and validation of a methodology for wind energy structures health monitoring
L’objectiu de la Monitorització de la salut estructural (SHM) és la verificació de l’estat o la salut de les estructures per tal de garantir el seu correcte funcionament i estalviar en el cost de manteniment. El sistema SHM ...
Experimental and theoretical analysis of flow and sediment transport in 90-degree fluvial diversions.
Fluvial bifurcations are systems that have a great influence on human society. Their formation and evolution can affect to activities as agriculture or industry and a good knowledge of the mechanisms that affect the processes ...
Modelación numérica integrada de los procesos hidráulicos en el drenaje urbano
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 ...
Comportamiento hidráulico de aliviaderos escalonados sin cajeros laterales en presas de HCR
Tradicionalmente la construcción de aliviaderos escalonados en presas de hormigón compactado con rodillo (HCR) se caracteriza por la presencia de muretes guías que imponen un ancho constante a lo largo del aliviadero y que ...
Assessing debris-flow hazard focusing on statistical morpho-fluvial susceptibility models and magnitude-frequency relationships. Application to the central-eastern Pyrenees
Occurrence of debris flows has received little attention in the Pyrenees, probably due to the small risk faced by most of the debris-flow prone sites in this mountain range. Nevertheless, the event of Biescas, which occurred ...
Numerical modeling of delayed and progressive failure in stiff clays with two-stage softening behaviour
Based on the laboratory, field and numerical results, the post-rupture strength defined firstly by Burland (1990) is verified and introduced in this thesis to describe the two-stage post-peak strain-softening characteristics ...
Shape dynamics and lipid hydrodynamics of bilayer membranes: modeling, simulation and experiments
Biological membranes are continuously brought out of equilibrium, as they shape organelles, package and transport cargo, or respond to external actions. The dynamics of lipid membranes are very complex due to the tight ...
Adaptive hybrid discontinuous methods for fluid and wave problems
This PhD thesis proposes a p-adaptive technique for the Hybridizable Discontinuous Galerkin method (HDG). The HDG method is a novel discontinuous Galerkin method (DG) with interesting characteristics. While retaining all ...
Evolución de las áreas productivas y sus requerimientos de insfraestructuras de urbanización
Las transformaciones que se han venido produciendo en el sistema productivo, a lo largo de los últimos cincuenta años en España, con la pérdida de peso de la actividad propiamente manufacturera en beneficio de los servicios, ...
PIV applications in vortex rings and oscillatory boundary layers
Particle Image Velocimetry (PIV) is one of the most used experimental techniques in fluid mechanics to obtain the velocity field of a flow. One of its most celebrated characteristics is that it does not have interference ...
Model predictive control of resonance sensitive irrigation canals
Saving water is an economic and ecological need. One way to save water is to reduce losses in irrigation networks by canal automation. The goal of canal automation is to make the right amount of water to at arrive in the ...
