La tesis se enmarca en la caracterización, a nivel material, de la fractura del hormigón reforzado con fibras de acero (SFRC) bajo solicitaciones de tracción y cortante, y sobre la determinación de parámetros que representan ...
Ocean turbulence is a classic example of turbulent motion and observations of turbulence in the ocean lack in regions of complex topography since in-situ and experimental data are complicated to obtain. As a result, ocean ...
The objective of the thesis is to develop a numerical tool to describe how the concentration of one or more substances distributed in a fluid environment changes under the effect of three transport processes: advection, ...
This thesis develops numerical methods to improve the accuracy and computational efficiency of the part-scale simulation of Additive Manufacturing (AM) (or 3D printing) metal processes. AM is characterized by multiple ...
El flujo desbordado en secciones de ríos con llanuras de inundación (secciones compuestas) presenta fuertes fenómenos tridimensionales que lo diferencian del flujo confinado en el cauce principal (asimilable a secciones ...
(English) Cycles in the construction sector and economy disguise what appears to advance in occupational risk prevention when, unfortunately, the AECO sector maintains very high accident rates. The zero accident target is ...
Seawater intrusion (SWI) consists in the movement of seawater (SW) into freshwater (FW) aquifers, contaminating drinking water resources. SWI, along with the parallel reduction of Submarine Groundwater Discharge may lead ...
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 ...
En la ingeniería estructural, uno de los desafíos constantes es encontrar nuevas formas de proteger las estructuras de las fuerzas medioambientales. El aislamiento sísmico se ha mostrado como una forma efectiva de reducir ...
This dissertation presents high-order hybridisable discontinuous Galerkin (HDG) formulations coupled with implicit Runge-Kutta (RK) methods for the simulation of one-phase flow and two-phase flow problems. High-order-methods ...
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 ...
This thesis aims to develop a High-Performance Computing implementation to solve large composite materials problems through the use of the FE2 multi-scale method. Previous works have not been able to scale the FE2 strategy ...
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 ...
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 ...
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 ...
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, ...
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 ...
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, ...
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 ...
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 ...
