Long-term privacy in electronic voting systems
This PhD thesis focuses on lattice-based cryptography and how to apply it to build post-quantum online voting systems. It is the result of the research done by the author at Scytl in close collaboration with Dr. Paz Morillo, ...
Ab-initio quantum Monte Carlo study of ultracold atomic mixtures
The properties of mixtures of Bose-Einstein condensates at T=0 have been investigated using quantum Monte Carlo (QMC) methods and Density Functional Theory (DFT) with the aim of understanding physics beyond the mean-field ...
Spacecraft state propagation and orbit determination using jet transport
The motion of space objects is strongly nonlinear and non-integrable since it is not only affected by the Keplerian central gravity of the Earth, but also subjected to some complex perturbations. Either an accurate and ...
Probabilistic characterization of single and concurrent metocean variables of Mexican coasts with seasonal variability using extreme value theory, with application to reliability of coastal structures
This thesis encompasses a set of different subjects related to metocean variables but studied from different perspectives. The metocean variables are mainly significant wave heights and wind velocities and, to a lesser ...
Study on crystallinity, properties and degradability of poly-4-hidroxybutyrate and related polyesters
In the last decades, polymeric biomaterials, due to their advanced physical and mechanical properties, have been used in a vast variety of surgical and pharmaceutical applications. In this thesis, a study on crystallinity, ...
Proper generalized decomposition solutions for composite laminates parameterized with fibre orientations for fast computations
Composite materials are gaining popularity as an alternative to classical materials in many different applications. Moreover, their design is even more flexible due to the potential of additive ...
Arquitectura y genética: como analogía en el proceso de diseño arquitectónico
Due to the progressive development of new technologies, modern society is experiencing quite a degree of disconnection from the elements of nature. This is reflected in increased levels of stress, anxiety and depression, ...
Risk-based highway bridge inspection intervals
Infrastructure maintenance programs establish schedules for routine inspections of highway bridges with little consideration of their current conditions. The time interval between two inspections is traditionally set based ...
Computational modeling of adsorption packed bed reactors and solar-driven adsorption cooling systems
Environmental concerns regarding climate change and ozone depletion urge for a paradigm shift in the cooling production. The cooling demand exhibits an alarmingly increasing trend, thus its satisfaction in a sustainable ...
New phenomena in high-quality suspended nanotube devices
Carbon nanotubes (CNTs) have attracted the attention of the scientific community since their discovery in the 90s. They are an excellent material for the development of research fields as diverse as nanomechanics or quantum ...
Deterministic control of nanoantenna and single-photon emitter interaction at the nanoscale
The study of light-matter interaction at the nanoscale is a very promising field of research, providing the possibility to manipulate the interaction with single quantum systems like single atoms, molecules, atomic defects ...
Urban park a new typology of built-up nature : towards a new urban green language for Barcelona
This thesis aims to generate a new vision for the park division and introduce a new model of parks called Urban Park. Urban Park should follow specific features and unique characteristics that made it suitable to be ...
Experimental and numerical modelling of CO2 behaviour in the soil-atmosphere interface : implications far risk assessment of carbon capture storage projects
CO2 geological storage is considered one of the options technologically viable in order to decrease the industrial emissions of this gas species that strongly contribute to the greenhouse effect in the atmosphere (IPCC, ...
Machine learning for quantum physics and quantum physics for machine learning
Research at the intersection of machine learning (ML) and quantum physics is a recent growing field due to the enormous expectations and the success of both fields. ML is arguably one of the most promising technologies ...
Object manipulation based on tactile information
In-hand dexterous manipulation of an object is the ability to change the configuration (position and/or orientation) of an object held in the hand. This is an ability that has allowed humans to use tools and interact with ...
Advanced energy management/control strategies for smart manufacturing systems
This thesis is devoted to the study of the optimisation-based control techniques for the design of control strategies that contribute to improve the energy efficiency of smart manufacturing systems. Currently, manufacturing ...
Valorization of low concentration sugar side-stream from dissolving pulp production
Among the platform chemicals that can be produced from lignocellulosic biomass, furfural (FUR) constitutes a promising intermediate that can be processed into a variety of advanced end products. In this thesis, the ...
Redistribución del uso del espacio viario como gestor eficiente de movilidad
The efficient and equitable use of urban road space considered as a public good and a scarce resource, leads to giving priority to sustainable transport modes (walking, cycling and public transport). Private vehicle sees ...
Sports broadcasting and multiple object tracking with deep learning methods
Since less than a decade ago, deep learning techniques started to dominate many different fields, revolutionizing the possibilities of artificial intelligence. Seeing their potential, industrial sectors started to invest ...
Special values of the triple product p-adic L-function
Let E be an elliptic curve defined over the field of rational numbers and let f be the corresponding newform of weight 2. Let g,h be two weight one newforms whose nebentype characters are mutually inverse. Let V be the ...
