On scalable, reconfigurable, and intelligent metasurfaces
Sixth Generation (6G) of wireless networks will be even more heterogeneous and dense as compared to Fifth Generation (5G) and other legacy networks. Thus, the 6G architecture will need to be adapted to serve the ever-evolving ...
Ejection-collision orbits in the restricted three-body problem
The main objective of this dissertation is the study of the ejection-collision (EC) orbits in the circular and planar Restricted Three Body Problem (RTBP from now on). In particular, we will focus on the analytical and ...
Quantifying uncertainty in complex automotive crashworthiness computational models : development of methodologies and implementation in VPS/Pamcrash
The automotive industry is constantly involved in the development of new methodologies and projects with the aim of reducing costs. During the vehicle design process, one of the most significant cost arises from building ...
Data–driven Bayesian networks modelling to support decision–making : application to the context of Sustainable Development Goal 6 on water and sanitation
We live in a complexand interconnected world which permeates ditterent scales. sectors or decision problems. This fact is acknowledged by the United Nations 2030 Agenda for Sustainable Development, which underscores current ...
Contribución a la metodología de caracterización dinámica de materiales resilientes para aplicaciones ferroviarias
This thesis is focused on the enhancement and development of advanced methodologies for the dynamic characterisation of resilient elements used in railway applications. On the one hand, this thesis proposes several ...
Finite element methods for advection-diffusion-absorption and fluid flow problems
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, ...
Essays on second-best pricing schemes for transport infrastructure
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 ...
From low carbon buildings to sustainable cities : sustainability transitions in the built environment towards the UN Agenda
This thesis addresses sustainability transitions in the built environment, from buildings to the metropolitan scale, while ranging from low carbon development to the multidimensional challenges currently faced by cities. ...
Next generation overlay networks : security, trust, and deployment challenges
Overlay networks are a technique to build a new network on top of an existing one. They are a key tool to add functionality to existing networks, and are used in different layers of the Internet stack for a wide variety ...
Ultrasound micromolding technique and real-time X-ray diffraction using synchrotron radiation : applications to porous scaffolds for biomedical devices and study of thermal-induced transitions
Current market trend is moving to miniaturized specimens, especially in the biomedical field seeking high effective and less invasive treatrnent. Ultrasound (US) micromolding is a new technique developed to the aim of ...
Evaluación del impacto del Cambio Climático (escenarios B1 y A2) en las aportaciones futuras generadas para el horizonte de proyección 2000-2050 en las cuencas del Fluvià y la Tordera en Catalunya
The results presented in this doctoral thesis aims to evaluate the possible Climate Change effects on the water resources yield by the Fluvià river basin and the Tordera river basin, both located in the autonomous region ...
A contribution to sustainable management of integrated material/energy networks in process industries
Towards sustainability forces process industries to change their traditional patterns. Therefore, efficient retrofitting has been a significant challenge and raised several issues, motivating the process system engineering ...
Computational modeling and rational design of flexoelectric metamaterials and devices
Piezoelectricity, the two-way coupling between electric polarization and strain is the basic mechanism behind most electromechanical transduction technologies. It is possible only in a limited number of materials, namely ...
A study of epoxy composites for high thermal conductivty applications
Nowadays. both electronic and microelectronic circuits have great relevance and wide application in our daily lives and are increasingly being used with higher powers and frequencies. One of the main problems faced by their ...
Surface characterization and cell instructive properties of superficially modified dental zirconia
Tetragonal polycrystalline zirconia doped with 3 mol% yttria (3Y-TZP) has become one of the most popular dental ceramics. Thanks to its outstanding mechanical properties (including high hardness. Toughness and wear ...
Marine sensor interoperability applied to in situ ocean sound processing
There has always been background sound in the oceans due to natural factors. However, since the first hydrophone deployments at mid-20th century, measured ocean sound levels have been steadily rising due to an increment ...
Construction and post-construction performance of vertical breakwaters on soft soils : the Port of Barcelona case
The design and construction of vertical caisson breakwaters on soft soils represents a significant challenge for the engineering of marine structures. Past experience reveals that this type of structures is sometimes prone ...
Preparation and characterization of reactive extrusion modified PLA/ABS blends and its foams
The current thesis takes place within the context of the projects MAT2016-80045-R "Aplicaciones industriales de compuestos y mezclas basados en REX-PLA" and the project "PLAIABS Blends: Recydability and weight reduction" ...
Numerical modeling of the underwater acoustic impact of offshore stations
The design of offshore power stations (for wind, wave or tidal energy generation) requires assessing their environmental impact. In particular, it is of the major importance to predict the impact of the generated subsea ...
La excepción : tres dimensiones de la discontinuidad en el paisaje de la Barcelona contemporánea
In this thesis discontinuity is treated as an exception in the discourse or as a spelling license in the urban (con)text. In the first place, interruptions in urban routes are studied, the moments in which flows, movement, ...
