(English) The present thesis focuses on developing, implementing, and evaluating a comprehensive community and impact-based early warning system (EWS) framework to support the protection actions of authorities and citizens ...
This thesis presents an efficient methodology to couple Model Order Reduction techniques within the framework of geophysical probabilistic inversion problems. Accurate models of the interaction between Earth inner processes ...
Este trabajo tiene por objetivo desarrollar una estrategia orientada a resolver de forma computacional el equilibrio estático de las obras pétreas formadas por elementos unidimensionales empleando la analogía clásica de ...
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 ...
Flash floods are one of the most devastating natural hazards, claiming numerous lives and tremendous economic losses. One of the main reasons for their catastrophic potential is the limited time available for precautionary ...
(English) This thesis investigates numerical methods for the simulation of surface water flows, focusing on the interaction between the large scale and the local scale and its application to natural hazards. Several families ...
The main target of this research is to develop a numerical model for debris flow simulations. As it is known, in general, this kind of flows occur in steeped mountain slopes. When dealing with the complete 3D physic system ...
En esta tesis se ha desarrollado y validado un modelo tridimensional de circulación costera en elementos finitos capaz de simular una región limitada del océano. La escala de longitud de las aplicaciones pueden ser del ...
The automotive industry is constantly involved in the development of new projects aimed at reducing weight, fuel consumptions and costs while improving passengers¿ safety. In order to achieve these increasing demands, ...
In numerous applications, two-phase liquid-gas transport at sub-millimeter length scales plays a substantial role in the determination of the behavior of the system at hand. As its main application, the present work focuses ...
The presence of a reservoir and its construction generate a direct impact in the rivers and in the surrounding landscape. The effects of the existing reservoirs, plus the combination of these with power plants (that use ...
Torrential flows have so far been studied less than have river flows, due to the difficulty of faithfully reproducing them in the laboratory, and the few field measurements available. For this reason, this present research ...
This thesis aims to develop a predictive control for irrigation canals to improve the management of water resources. Water is necessary for life and it is a scarce good that we need for drinking, in the agriculture, etc. ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
The aim of this work is the study of laboratory effects on the measurement of wave impact induced loads on rigid maritime structures. A high number of experiments (more then 4000 using regular wave attacks) have been carried ...
