Spatiotemporal coordination of collective activity in neuronal ensembles
The brain is a complex multiscale dynamical system made of neurons, connected with each other by synapses. Neurons are multidimensional nonlinear systems able to exhibit dynamical activities at different temporal and spatial ...
Observation and interpretation of type IIB supernova explosions
Core-collapse supernovae (CC-SNe) explosions represent the final demise of massive stars. Among the various types, there is a group of relatively infrequent CC-SNe termed type IIb, which appear to be hybrids between normal ...
Effects of vibrations applied to fluids at different gravity levels
Due to the increasing interest in space exploration, management of two-phase flows in the absence of gravity has become a key aspect in improving the efficiency of technological applications for space missions. Understanding ...
ISFAA : Implicit SPH for astrophysical apllications
Computational simulation is one of the basic techniques of modern Astrophysics. The long-term time astrophysical processes cannot be treated with explicit approaches because that they are limited, in their maximum time ...
On cross-shore beach profile morphodynamics
The nearshore zone is plenty of 3D morphodynamic patterns resulting from the interaction of waves, currents and sediments. The dynamics of formation and evolution of these patterns is at present a controversial point in ...
Ion binding landscapes and molecular dynamics of phospholipid membranes
This thesis aims at studying the physical-chemical properties of model lipid bilayers in physiological environments. Since in such conditions biological membranes composed of phospholipids and cholesterol are surrounded ...
Mapping biophysics through enhanced Monte Carlo techniques
This thesis is focused on the study of molecular interactions at the atomistic detail and is divided into one introductory chapter and four chapters referencing different problems and methodological approaches. All of them ...
Experimental and numerical study of the symbolic dynamics of modulated semiconductor lasers with optical feedback
The goal of this thesis is to investigate the influence of current modulation in the dynamics of the low-frequency fluctuations (LFF) regime induced by optical feedback in semiconductor lasers. In this regime the laser ...
Dynamics of metallic glasses explored by mechanical relaxation
Dynamic mechanical analysis (DMA) is often used to explore the relaxation dynamics of metallic glasses (MGs). Secondary relaxations in metallic glasses appear as an excess wing, as a shoulder of the primary relaxation peak ...
Convección natural en cavidades tridimensionales
The modelling of convective transport processes involving heat and mass transfer in an incompressible Newtonian fluid in cylindrical domains is a relevant research subject both for theoretical research and for industry. ...
Relaxation dynamics in disordered systems
The nature of the glass transition and of the glassy state is a fundamental and still unsolved problem of condensed matter physics. Many liquids can be supercooled below their melting point without crystallizing, that is, ...
Ab initio molecular dynamics study of thiolate-protected gold clusters and their interaction with biomolecules
Thiolate monolayer-protected gold clusters (AuMPCs) are being used in various biological and biomedical applications due to their unique physical and chemical properties. The fact that gold-sulphur bonds are very stable ...
Disentangling climatic interactions and detecting tipping points by means of complex networks
En una situación de grandes cambios climáticos, el conocimiento de el sistema Tierra ha devenido, en los últimos años, una de las tareas mas importantes para la comunidad científica. En los últimos diez años, el incremento ...
Nocturnal coastal fronts in the Mediterranean basin
The main goal of this thesis is to investigate the formation of nocturnal coastal fronts (hereafter CF) in the Mediterranean basin producing nocturnal offshore precipitation near the coastline. After sunset the cooled ...
White dwarf dynamical interactions
Merging white dwarfs is a promising channel to trigger Type Ia supernovae, known as the double degenerate scenario. Supernovae are stellar explosions that radiate as much energy as any ordinary star is expected to emit ...
Microscopic description of two dimensional dipolar quantum gases
A microscopic description of the many-body properties of anisotropic homogeneous gases of bosonic dipoles in two dimensions is presented and discussed. By changing the polarization angle with respect to the plane, we study ...
Climate networks constructed by using information-theoretic measures and ordinal time-series analysis
This Thesis is devoted to the construction of global climate networks (CNs) built from time series -surface air temperature anomalies (SAT)- using nonlinear analysis. Several information theory measures have been used ...
Numerical modeling of simple laboratory experiments of rotating flows
Despite the large amount of research which has been conducted on turbulent flows, a full understanding of their dynamics as well as the mechanisms involved in the onset of turbulence is still missing. Experimental studies ...
Variational mechanics and stochastic methods applied to structural design
This thesis explores a very well understood area of physics: computational structural dynamics. The aim is to stretch its boundaries by merging it with another very well established discipline such as structural design and ...
Latest generation white dwarf cooling models : theory and applications
White dwarfs are the most common stellar evolutionary end-point. Moreover, they can be considered as reliable cosmic clocks to infer the age of a wide variety of stellar populations, including globular and open clusters. ...
