Local optics corrections in the HL-LHC
In order to increase the performance of particle colliders, it is crucial to make the beam sizes at the collision points as small as possible. This causes an increase of the beam size in the region surrounding the collision ...
Selenium and zinc enriched bioproducts generated from wastewater as micronutrient feed supplements and biofertilizers
This thesis aimed to explore the potential of Se/Zn-enriched bioproducts produced from wastewater treatment processes by eco-technologies (phytoextraction, bioreduction and microalgae-based systems) as Se/Zn feed supplements ...
Análisis de la respuesta dinámica en agitadores industriales
In food and pharmacological industries, reducing the production time and improving the machine flexibility to be adapted to new products is a constant necessity. This generate changes on the initial working conditions for ...
L'abstracció del territori
A tesi cerca delimitar instruments d’anàlisi que permetin una descripció geomètrica del territori tant en quant la percepció de la seva forma com respecte a una possible estructura d'aquesta mateixa. El primer capítol ...
Data science in HIV : statistical approaches for therapeutic HIV vaccine data
The present dissertation contributes to Data Science in the Human lmmunodeficiency Virus (HIV) field, addressing specific issues related to the modelling of data coming from three different clinical trials based on ...
The embedding problem for Markov matrices
The goal of this thesis is to solve the embedding problem for Markov matrices, posed by Gustav Elfving in1937. A Markov matrix is non-negative square matrix whose rows sum to 1. We say that such a matrix M is embeddable ...
Structural system identification by dynamic observability technique
Structure system identification (SSI) can be classified as static and dynamic depending on the type of excitation. SSI by Observability Method (OM) using static tests was proposed and analyzed to address the observability ...
Proposing some innovative study design features to regulatory agencies (EMA and FDA) in bioequivalence trials : Reference Scaled Average Bioequivalence, and Two-Stage Adaptive Designs
In applications for generic medicinal products the concept of bioequivalence is fundamental. Two medicinal products, i.e. a test and a reference drugs containing the same active substance are considered bioequivalent if ...
Hydrodynamics and geochemistry at multiple scales : characterizing preferential flow-paths and wormholes in evaporitic sediments
The characterization of evaporitic aquifers for a better understanding of hydrodynamics and geochemical processes is of great importance, especially in environments where both the sustainability of unique ecosystems and ...
Synthesis and characterization of polycarbonates from epoxidized vegetable oils, propylene oxide and carbon dioxide
The current research is primarily focused on the preparation of a polycarbonate using epoxidized linseed oil (ELO) and epoxidized soybean oil (ESO) as feedstocks. The presence of unsaturation in vegetable oil structure ...
Desarrollo e implementación de una formulación utilizando la teoría de mezclas serie/paralelo para la modelización de estructuras navales de materiales compuestos sometidas bajo cargas cíclicas
The main goal of this thesis is the simulation of the performance of composite naval structures subjected to cyclic loads. The predicted behavior expected is the fatigue life of the composite structure, as well as the ...
Constant effect in randomized clinical trials with quantitative outcome : a methodological review
The past decade has seen continuous growth in so-called precision medicine, due especially to great advances in the genetics. While applying it presently goes unquestioned in certain fields like oncology, it is more ...
Estudio de las propiedades fisicas en regiones chocadas en nebulosas planetarias
Planetary nebulae play a very important role in the chemical evolution of galaxies since they are responsible for returning nuclear-processed material to the interstellar medium. Observations of planetary nebulae are used ...
The geometry and topology of steady Euler flows, integrability and singular geometric structures
In this thesis, we make a deep investigation of the geometry and dynamics of several objects (singular or not) appearing in nature. The main goal is to study rigidity versus flexibility dynamical behavior of the objects ...
Micromechanical properties of inorganic multiphase materials
This thesis is dedicated to understanding the micromechanical properties of multiphase materials which are indispensable in today’s engineering applications. The mechanical behavior of these materials is dictated by the ...
A double-porosity formulation for the THM behaviour of bentonite-based materials
The thermo-hydro-mechanical (THM) behaviour of expansive clays has been extensively studied in the last decades due to the potential use of bentonites as components of engineered barrier systems (EBS) in deep geological ...
A theoretical and computational study of the interaction between biomembranes and curved proteins
Organelles are the smallest functional parts of eukaryotic cells. Among them, some are membrane-bound such as the nucleus, the endoplasmic reticulum, or the Golgi apparatus, each of them with essential biological functions. ...
Large-scale imaging of optical antennas and single molecules
The interaction of light and matter is of crucial importance in fundamental science as well as in high-end technology. Ultimately, this concerns the interaction between a photon and a single quantum system, e.g. the ...
Park Güell : arquitectura conformada por el agua : gestión hídrica para la reforestación de la Montaña Pelada en Barcelona
In this thesis we tried to demonstrate that Park Güell of Barcelona (1900-1914), projected by Antonio Gaudí, is a rainwater receiver destined to control the erosion and to support to the reforestation. The slope where the ...
Hyperspectral imaging system for the fast recording of the ocular fundus
Vision loss affects physical, psychological, and emotional wellbeing and social life as well. High life expectancy and health policies are translated into an aging population worldwide, which has higher risk of eye’s ...
