Causal inference and forescasting methods for climate data nalysis
To advance time series forecasting we need to progress on multiple fronts. In this thesis, we develop algorithms to identify causal relations which allow to identify the driving processes containing useful information for ...
Síntesis de nanoparticulas multifuncionalizadas tipo Core-Shell mediante rutas quimicas
In this thesis, the results of different core-shell structures are presented after having been synthesized by the modified Stöber method, results of UV-Vis, SEM, TEM, XRD, among others, are shown, which determined the ...
Computer modeling of the polarity and amoeboid motion of living cells
Cell motility is important in many biological processes. Some examples relay in epidermal cells moving towards lesions during wound healing, neutrophils cells migrating towards sites of bacterial infection as part of the ...
Organització espacial i temporal de la pluja a l'àrea metropolitana de Barcelona
In order to avoid the catastrophes caused by intense or even moderately intense, rainfall episodes, it is essential to have as exhaustive a knowledge as possible of the behaviour of the same. We have a source of information ...
Smart control of light in edge-emitting lasers
The invention of the laser triggered the study of light-matter interactions. In turn, the advent of artificial structured materials on micro- and nanometer scales has become a fruitful playground to tailor the propagation ...
Models of stellar winds from X-ray bursts
The study of stellar winds (SW) in the context of X-ray bursts (XRB) performed in this thesis has two main motivating issues. The first is whether or not the heavy elements produced from nucleosynthesis in XRBs can escape ...
Mathematical modelling to study infectious diseases: from understanding to prediction
Each year 10 million people die from communicable diseases. They are infectious diseases caused by agents transmitted between individuals. Nowadays, the two infectious diseases that have the greatest impact are tuberculosis ...
Propiedades vitreas emergentes en cristales moleculares
One of the most complex and unsolved problems in physics is the glass transition problem, in which the resulting state, the glass, exhibits unique and anomalous properties. During the transition, a kinetic freezing phenomenon ...
Dinàmica orientacional i estructura local en liquids moleculars sobrerefredats
The aim of this thesis is to study, by means of molecular dynamics simulations, the behaviour of two molecular models at different temperatures, approaching the glass transition. One of them mimics methanol molecules, ...
Force fields parametrization of lon-water interactions from density funcional theory based molecular dynamic simulations
The underlying topic of this thesis is the study of the application of the Force Matching (FM) algorithm to parameterize ion-water Force Fields using ab-initio simulations as reference. In order to do so three different ...
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 ...
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 ...
Corrosion studies on Cu-based alloys
Cu-based alloys are widely applied in corrosive environments. The improvement of the alloys' corrosion resistance will significantly reduce energy consumption and overexploitation of resources. To increase the resistance ...
Analysis and degradation mechanisms of enamels, grisailles and silver stains on Modernist stained glass.
Materials and methods used in the production of modernist (late 19th and early 20th century) stained glass from the city of Barcelona with special regards to the degradation mechanisms of enamels, grisailles and silver ...
Correlations in spin-orbit coupled ultracold quantum gases
The main goal of this thesis is the computation of ground state properties of quantum many-body systems under Spin Orbit coupling (SOC) interactions out of the ultradilute regime. We present two approaches to fulfill this ...
Quantum Monte Carlo study of few-and many-body bose systems in one and two dimensions
In this Thesis, we report a detailed study of the ground-state properties of a set of quantum few- and many-body systems by using Quantum Monte Carlo methods. First, we introduced the Variational Monte Carlo and Diffusion ...
Intracavity spatial filtering in broad area semiconductor laser
Semiconductor lasers in high-power regime typically manifest a poor beam quality due to its asymmetric beam divergence and its large beam quality factor (M2). The emission along one of the transverse directions (slow axis) ...
Large-scale CFD and micro-particles simulations in a large human airways under sniff condition and drug delivery application
As we inhale, the air drawn through our nose undergoes successive accelerations and decelerations as it is turned, split, and recombined before splitting again at the end of the trachea as it enters the bronchi. Fully ...
Exploring free-energy landscapes and microscopic interactions of selected small-molecules and proteins with cell membranes
The present Thesis is devoted to the study of the physical-chemical properties of selected small-molecules (such as amino-acids like tryptophan or hormones like melatonin) and proteins (such as KRAS-4B) absorbed in model ...
Hybrid non-destructive technique for volumetric defect analysis and reconstruction by remote laser induced ultrasound
This PhD thesis is devoted to the design, development and implementation of a non-contact hybrid non-destructive testing (NDT) method applied to the analysis of metallic objects that contain embedded defects or fractures. ...
