Hybrid CPU/GPU implementation for the FE2 multi-scale method for composite problems
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 ...
Modeling present and future freeway management strategies : variable speed limits, lane-changing and platooning of connected autonomous vehicles
Freeway traffic management is necessary to improve capacity and reduce congestion, especially in metropolitan freeways where the rush period lasts several hours per day. Traffic congestion implies delays and an increase ...
Decision analysis under uncertainity for sustainable development
Policy-making for sustainable development becomes more efficient when it is reliably backed by evidence-based decision analysis. Concretely, this is crucial in the planning of public services delivery. By translating "raw" ...
Monotonicity-preserving finite element methods for hyperbolic problems
This thesis covers the development of monotonicity preserving finite element methods for hyperbolic problems. In particular, scalar convection-diffusion and Euler equations are used as model problems for the discussion in ...
Identifying and managing hotspots to extreme events : application to NW Mediterranean conditions
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 ...
Design of reliable schedules and control strategies for improving bus system performance
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 ...
Zero-thickness interface elements in petroleum geomechanics : sand production and hydraulic fracture
This thesis describes the extension of the Finite Element Method with zero-thickness interface elements (FEM+z) to 3D, large and complex problems in geomaterials, with special interest in petroleum geomechanics. This general ...
Experimental analysis of soil cracking due to environmental conditions
This thesis presents an experimental approach on the subject of cracking in soils due to changes in environmental conditions, where research is mainly directed to the soil-air interface and the effect of boundary conditions. ...
Robust structural damage detection by using statistical hybrid algorithms
This thesis presents the results of applying a statistical hybrid approach for structural health monitoring using piezo actuating signals. Where, by combining statistical processing based on Principal Component Analysis ...
Estudi de la dinàmica del transport de dilucions salines d'alta concentració en canonades a pressió
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 ...
Three-dimensional numerical analysis of flow structure and sediment transport process in open channels
This research project focuses on the analysis and prediction of flow structures and sediment transport process in open channels by using three-dimensional numerical models. The numerical study was performed using the ...
Laboratory experiments to evaluate the joint effect between heterogeneity and head fluctuation on mixing, effective porosity and tailing
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 ...
Image processing and experimental techniques to characterize the hydraulic performance of grate inlets
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 ...
Análisis de las variables que inciden en la movilidad en vehículos motorizados de dos ruedas en la ciudad de Barcelona
MOBILITY provides accessibility to people, goods, services and information, favoring the implementation of socio-economic activities. The more efficient mobility becomes, the greater human development and quality of life ...
Scalable domain decomposition methods for finite element approximations of transient and electromagnetic problems
The main object of study of this thesis is the development of scalable and robust solvers based on domain decomposition (DD) methods for the linear systems arising from the finite element (FE) discretization of transient ...
Experimental characterization of turbulance in steep rough streams
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 ...
Vibroacoustic coupling and transmission paths
This dissertation deals with four topics. The first three are in the same environment, the transmission paths. The fourth refers to the synthesis of subsystems and more specifically to two subsystems linked by any number ...
Stress monitoring of cylindrical structures using guided waves
This thesis presents some approaches for guided wave based stress monitoring as a part of Structural Health Monitoring (SHM). SHM systems include different levels, from damage detection to prognosis, however, this work is ...
Optimization of yard operations in container terminals from an energy efficiency approach
This Thesis addresses common operational issues related to maritime container terminals. In the last decades, containerization of maritime transportation has grown very rapidly, forcing terminal operators to cope with ...
Multivariate characterization of wave storms in coastal areas
Wave-storms are the responsible of the main changes in the Coast. Their detailed characterization results in a better design of any marine structure. The most common approach to describe wave-storms is to simplify the event ...
