Collective motion and collective decision-making in animal groups : from scholling fish to swarming robots
(English) Collective behavior in animals is ubiquitous in nature. It emerges from the self-organization of interacting individuals within a group. What makes collective behavior so interesting is that the behavior of the ...
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, ...
Development and interactions of surfzone morphological patterns
A variety of morphodynamic patterns are typically present in the nearshore zone of sandy beaches that develop due to the interactions between waves, currents and the morphology. The most common are one or several nearshore ...
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, ...
Modelling emergent rhythmic activity in the cerebal cortex
The brain, a natural adaptive system, can generate a rich dynamic repertoire of spontaneous activity even in the absence of stimulation. The spatiotemporal pattern of this spontaneous activity is determined by the brain ...
Barocaloric effects at first-order phase transitions
Current refrigeration devices, based on vapour-compression cycles, employ refrigerants such as HFCs, which exhibit a global warming potential a thousand times higher than the one produced by CO2,. Furthermore, the increasing ...
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 ...
