High-level service bus systems, even though in many different forms and local particularities, have been spread out around the globe over the last decades, driven by the administration and the transport authority, and in ...
(English) This thesis provides tools, based on mathematical modelling, for the analysis, optimization and simulation, of vehicle-sharing systems. The thesis addresses various implementation levels of such systems, from ...
In recent years the scientific community has been developing new techniques in structural health monitoring (SHM) to identify the damages in civil structures specially in bridges. The bridge health monitoring (BHM) systems ...
(English) This thesis deals with finite element methods to solve compressible flow problems, an important branch of Computational Fluid Dynamics (CFD) whose applications are widespread in many areas of engineering and ...
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 Ground Penetrating Radar test applied to road engineering is overall used to determine the geometric characteristics of the pavement structure by analyzing the wave in the time domain. On many cases, it is often used ...
The use of concrete in disposal facilities to store low- and intermediate-level nuclear waste requires that the durability of this material is optimal for the lifetime of these repositories. One of the most important ...
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 ...
Floods and Drought are some of the most catastrophic natural disasters for humanity, averaging 1 to 5 billion dollar of annually damage for flood events and 6 to 8 billion dollars respectively for drought events. To avoid ...
More than one-third of Earths available freshwater is used for anthropogenic purposes, which has led to its contamination by numerous chemical compounds. Their presence in the environment might have negative consequences ...
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 ...
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 ...
El objetivo principal de esta tesis doctoral es profundizar en el conocimiento de los procesos biológicos responsables de la eliminación simultánea de nitrógeno y fósforo en un ARU de baja carga orgánica, mediante un reactor ...
Los objetivos de esta tesis doctoral son la caracterización de un agua residual urbana, la prefermentación del agua residual y la optimización de la eliminación biológica de nutrientes en el tratamiento del agua residual ...
The finite element method is a valuable tool for simulating complex physical phenomena. However, any finite element based simulation has an intrinsic amount of error with respect to the exact solution of the selected ...
Pricing has been advocated for a long time as a suitable policy instrument to deal with transport externalities. Recent technological developments enable the implementation of more sophisticated pricing schemes at affordable ...
Huge modifications have been made to landscape or urban watersheds, especially in twentieth century, caused by increases in urbanization have led to progressive increases in runoff flows and therefore sediment production. ...
The mining area in the Bages district, in Catalonia (Spain), is located between the villages of Cardona, Súria, Sallent and Balsareny. It contains the most important salt deposit in Europe, which has been exploited since ...
External reinforcement techniques with CFRP laminate adhered to concrete elements have advanced greatly over the past decade, obtaining a more effective method further lightweight and reliable. These advances have resulted ...
