A journey of Ultra Heavy Cosmic Ray Nuclei with Z≥65: From their detection near the Earth neighborhood back to their nucleosynthesis sites
Des de temps immemorials, dels principis de la humanitat, els éssers humans han mostrat un tremenda curiositat i atracció pel que veien quan enlairaven la vista. Per un motiu o un altra, la recerca d'explicacions de ...
A versatile system for the study of light-matter interactions at the level of individual particles
In this thesis, a single-atom trap in a "Maltese cross'' geometry (MCG) was designed, built up and characterized. A MCG atom trap uses four in-vacuum lenses to achieve four-directional high-numerical-aperture optical ...
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 ...
Active superelasticity in three-dimensional epithelia of controlled shape
Fundamental processes in development and physiology are determined by the three-dimensional architecture of epithelial sheets. How these sheets deform and fold into complex structures has remained unclear, however, because ...
Advances in fibre Bragg grating sensors for damage detection in composite laminates: application in quasi-static and fatigue delamination tests
The use of composite materials in industrial applications such as aeronautical, aerospace or wind energy production has greatly increased in recent decades. Due to their inherent properties, these materials allow lighter, ...
Analysis of energetic particle-driven Alfvénic instabilities in tokamak and stellarator plasmas using three dimensional numerical tools
In this thesis, a detailed analysis of the experientially observed energetic particle-driven Alfvénic instabilities in tokamak and stellarator plasmas using three dimensional numerical tools based on the reduced MHD model ...
Analysis of the Large Gamma Ray Flares of Mkn 421 as Observed with HEGRA CT1 on the Island La Palma in 2001
En este documento presentaré un resumen de mi análisis acerca de los periodos de gran actividad de emisión gamma en 2001 para el objeto Mkn421. <br/>El análisis clásico y los métodos de separación gamma/hadrón para los ...
Assessment of gas-surface interaction modelling for lifting body re-entry flight design
Space re-entry is a challenging endeavor due to the harsh thermo-chemical environment around the vehicle. Heat flux being the reference parameter for Thermal Protection System (TPS) design, the total energy transfer can ...
Assessment of virtual design and manufacturing techniques for fibre reinforced composite materials
Virtual tools are commonly used nowadays to optimize product design and manufacturing process of fibre reinforced composite materials. The present work focuses on two areas of interest to forecast the part performance and ...
Atomic imaging of complex molecular
One of the significant challenges of modern science is to track and image chemical reactions as they occur. The molecular movies, the precise spatiotemporal tracking of changes in their molecular dynamics, will provide a ...
Atomistic study of slip transfer in BCC metals
(English) The mechanical properties of structural materials, which are naturally polycrystalline, is defined by a number of physical processes that take place at different time and space scales. On several of those processes, ...
Calorimeter Reconstruction Innovations for the LHCb Experiment
Aquesta tesi se centra en contribucions de software per l'experiment LHCb al CERN, específicament pel sistema de calorímetres en el context de l'anomenat Upgrade I. Les contribucions principals se centren en l'estudi ...
Caracterització optoelectrònica de materials bidimensionals a altes freqüencies
Two-dimensional materials have a lot of applications in the electronic and photonic device design field, especially when they need to be flexible and transparent. In particular, high frequency applications, above 100MHz, ...

Se ha escogido la técnica PECVD para obtener depósitos de subóxido de silicio, SiOx, de espesores del orden de la micra, sobre substratos de Si de dos pulgadas. Hemos logrado depósitos con contenidos de oxígeno entre 1.3 ...
Characterization of the structure, stability, mechanical and electrochemical properties of metallic glasses
Metallic glasses are often referred as glassy or amorphous alloys. They lack long-range order and microstructural defects that are characteristics in crystals, such as grain and phase boundaries and dislocations. These new ...
Charged particle multiplicities in pp interactions at p s = 900 GeV and p s = 7 TeV measured with the ATLAS detector at the LHC
La tesis se centra en los estudios de la producción inelástica de las partículas cargadas en el colisionador LHC que opera en la frontera de la energía del centro de masa de 7 TeV. Los datos corresponden a 16 μb-1 de la ...
Charmed baryon resonances and mesons in hot and dense matter
In this thesis we have studied baryon resonances generated from the dynamical interaction of two hadrons. We are interested on this study as an alternative approach to explain the increasing number of observed charmed ...
Coarse-Grained Mean-Field Simulations of Surfactant Micelles: Static and Dynamic Equilibrium Properties
Les molècules de surfactants estan compostes per seccions hidrofíliques i hidrofòbiques del qual les interaccions oposades amb el medi solvent deriven en un comportament particular on, a una concentració de surfactant ...
A cold-atom approach to topological quantum matter across the energy scale
The outstanding progress achieved in the last decades to isolate and manipulate individual quantum systems has revolutionized the way in which quantum many-body phenomena, appearing across Nature's different energy scales, ...
