Risk analysis of jet fires thermal effects
(English) The historical analysis performed has shown that jet fires have been the origin of a high number of domino effect accidents, both in the process industry and in the transportation of flammable fluids by pipelines ...
Preclinical and clinical studies in oncology and endocrinology with diffuse light
(English) Near-infrared diffuse optical spectroscopy (DOS) techniques are capable of non-invasive measurement of microvascular hemodynamic parameters of deep tissues (>1 cm penetration). One important focus of the field ...
Quasi-perfect codes for the classical-quantum channel
(English) Quantum computers use the laws of quantum mechanics to do complex operations that classical computers can't solve. Quantum computers and other physical quantum systems require quantum information to be completely ...
Análisis y propuestas en las operaciones para reducir los accidentes en buques de pesca artesanal españoles
(English) This thesis deals with the analysis of maritime accidents that occurred in fishing. The concept of maritime accident is important, since in this work we focus on these accidents and at the same time we move away ...
Mathematical and computational modeling of flexoelectricity at fixed and moving interfaces, fracture surfaces and contact
(English) Flexoelectricity is a two-way coupling between strain gradient and polarisation or strain and polarization-gradient. Harnessing flexoelectricity as a functional property requires gradient engineering. This is a ...
Elliptic problems: regularity of stable solutions and a nonlocal Weierstrass extremal field theory
(English) This PhD dissertation deals with qualitative questions from the theory of elliptic Partial Differential Equations (PDE) and integro-differential equations. We are primarily interested in a distinguished class of ...
Heat transfer correlations for liquid metal flows under nuclear fusion conditions
(English) This thesis focuses on modeling the circulation of liquid metal through the breeding blanket channels of a tokamak fusion reactor. Apart from extracting the heat produced by the nuclear reactions of the plasma, ...
Modeling of container throughput in the European port system-analysis of container liner shipping networks
(English) This thesis records the evolution of the container throughput dynamics of the European port system from 2001-2020, analyses the dynamics of the European container port hierarchy with methodologies that have not ...
Clinical evaluation towards the development of a lower limb exoskeleton for people with spinal cord injury: from gait biomechanics to motor learning
(English) People with spinal cord injury (SCI) may suffer lifelong sequels that influence every aspect of their lives, including motor and/or sensory impairment, difficulty breathing and/or swallowing, bladder/bowel weakness, ...
Quick assessment through analytical solutions of induced seismicity in geo-energy applications
(English) Understanding the triggering mechanisms of induced seismicity remains one of the most critical challenges in geo-energy applications. This Thesis aims at assessing (1) fault stability and induced seismicity ...
Bioactive ion-releasing platforms for regenerative medicine applications
(English) One of the most exploited tissue-engineering-based strategies nowadays is to use scaffolds that allow local stimulation of the targeted tissues, increasing therapy effectiveness while reducing toxicity. Therefore, ...
Spatio-temporal quality metrics for satellite SAR interferometric data
(English) The availability of RADAR images for monitoring Earth’s surface and its changes over time prompt the development of several interferometric SAR (InSAR) algorithms and methodologies. The Multi-temporal InSAR ...
Surgical subtask automation for intraluminal procedures using deep reinforcement learning
(English) Intraluminal procedures have opened up a new sub-field of minimally invasive surgery that use flexible instruments to navigate through complex luminal structures of the body, resulting in reduced invasiveness and ...
High-performance computing fluid-structure interaction model of bioprosthetic aortic valve replacements
(English) Computational modeling and simulation (CM&S) provides a powerful cost- and time-efficient tool to access detailed mechanistic information of biomedical problems, which is not accessible in either clinical imaging ...
Converged RAN/MEC slicing in beyond 5G (B5G) networks
(English) The main objective of this thesis is to propose solutions for implementing dynamic RAN slicing and Functional Split (FS) along with MEC placements in 5G/B5G. In particular, this thesis is divided into three parts. ...
Real-time solutions of parametric thermo-hydro-mechanical problems with proper generalized decomposition
(English) The Proper Generalized Decomposition (PGD) is a mathematical framework belonging to the Model Order Reduction (MOR) class of techniques. To the best of the author's knowledge, this methodology has not been applied ...
Obtaining, characterizing and studying the in vitro bioavailability of different cation complexations for food fortification
(English) Although mineral chelates have been produced for more than 70 years, neither production methods nor optimum conditions are well specified. The solid evidence that the complexes are true chelates is still missing. ...
Hydrodynamic models of accretion onto rotating compact stars
(English) Hydrodynamic models are essential for our understanding of the physics of stellar explosions, and specifically, for their potential contribution to the Galactic chemical abundances. In this Work, a one-dimensional ...
Machine learning techniques for adaptive polynomial and neural network digital predistorters
(English) The power amplifier (PA) is a core element in the radio transmitters to support the required mobile and fixed broadband communication link ranges. However, the PA is a power-hungry and nonlinear by nature device. ...
Polymer blends based on postconsumer waste of opaque poly(ethylene terephthalate) and polypropylene
(English) In recent years, new white and opaque PET bottles (PET-O) have appeared and are used for packaging dairy products. These bottles contain titanium dioxide (TiO2) particles to prevent deterioration of the packaged ...
