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 ...
Hidrometeorología y balance térmico de la marisma de Doñana
Doñana marshes are a wetland of ecological relevance at an international level. They are located on the right bank of the final Guadalquivir River, in the regions of Huelva and Seville in SW Spain. They occupy an area of ...
Highway travel time estimation with data fusion
La informació sobre el temps de viatge és l'indicador clau en el funcionament operatiu d’una autopista i un dels inputs més apreciats pels seus usuaris. Tot i això, no ha estat fins molt darrerament que els operadors ...
The Fixed-Mesh ALE method applied to multiphysics problems using stabilized formulations
The finite element method is a tool very often employed to deal with the numerical simulation of multiphysics problems.Many times each of these problems can be attached to a subdomain in space which evolves in time. Fixed ...
Bedload transport of sand-gravel mixtures with antidunes: flume experiments
In this thesis, the interaction between flow and sediment in alluvial channels is studied from an empirical approach, for conditions close or pertaining to supercritical flow, and for four types of sediment: sand, gravel ...
Representació gràfica del planejament: evolució del model i perspectives davant dels nous reptes de l'ordenació.
Throughout history, man has had the need to communicate through drawings, and drawing has evolved as another language. The technical aspect of drawing has sought to represent objects as faithfully as possible, both insofar ...
Thermo-hydro-mechanical impacts of carbon dioxide (CO2) injection in deep saline aquifers.
Los procesos termo-hidro-mecánicos relacionados con el almacenamiento geológico de carbono deben ser entendidos y cuantificados para demostrar a la opinión pública de que la inyección de dióxido de carbono (CO2) es segura. ...
El règim tèrmic del tram inferior de l'Ebre i les seues alteracions.
This thesis deals with the study of the thermal regime of the lower Ebro River (Spain), between the towns of Escatrón and Miravet, at different time scales (multiannual, annual, monthly, diel), as well as the alterations ...
Numerical approach for modeling steel fiber reinforced concrete
One alternative to overcome the main drawbacks of plain concrete in tension (its brittleness and weakness) is Steel Fiber Reinforced Concrete (SFRC), a technique introduced in the 70's, which consists of adding steel fibers ...
