Osychenko, Oleg N. (Fecha de defensa: 2012-12-20)
The Thesis is devoted to simulations of quantum phase transitions by means of Quantum Monte Carlo techniques. Quantum phase transition is a transition between phases at zero or low enough temperature, where quantum effects ...
Espinar Calvo, María Lorena (Fecha de defensa: 2012-12-21)
El objetivo de esta Tesis es el estudio de diferentes comportamientos celulares dinámicos en Escherichia coli y Bacillus subtilis. Es interesante comprender cómo estos organismos sencillos poseen mecanismos complejos para ...
Monterrubio Velasco, Marisol (Fecha de defensa: 2013-03-15)
Mediante el análisis estadístico y utilizando diversas técnicas fractales en esta tesis se estudia el comportamiento temporal y espacial de tres series de réplicas sísmicas ocurridas en el Sur de California, que tuvieron ...
Duarte Correa, María Jazmín (Fecha de defensa: 2013-05-31)
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 ...
Panadès i Guinart, Carles (Fecha de defensa: 2013-06-28)
Even though the transition to turbulence has been studied for over a century, its complete comprehension still remains unclear even for the simplest flows and continues to be a daunting challenge for the scientific community. ...

L’objectiu principal d’aquesta tesi és avançar en la comprensió del processament d’informació en xarxes neuronals en presència d’oscil lacions subumbrals. La majoria de neurones propaguen la seva activitat elèctrica a ...
Rué Queralt, Pau (Fecha de defensa: 2013-07-25)
This Thesis studies different cellular and cell population processes driven by non-linear and stochastic dynamics. The problems addressed here gravitate around the concepts of transient dynamics and relaxation from a ...
Camacho Díaz, Judit (Fecha de defensa: 2014-06-19)
Since white dwarfs are the final stage of the evolution of the vast majority of stars, they carry important information about the chemical evolution of our Galaxy, its star formation rate, and its structure and dynamics. ...
Iqbal, Muhammad Zahir (Fecha de defensa: 2014-07-16)
Graphene, a two-dimensional sp2-hybridized network of carbon atoms has received a remarkable cornucopia of new physics and served as a unique model system, due particularly to its electronic properties, which could have ...
Blay Carreras, Estel (Fecha de defensa: 2014-07-21)
The atmospheric boundary layer is the part of the troposphere influenced by the presence of the surface, and where most weather phenomena occur. During the day, with fair weather conditions, a convective boundary layer ...
Rovira Esteva, Muriel (Fecha de defensa: 2014-09-26)
Neutron diffraction is a powerful technique that allows to probe the structure of disordered phases across a variety of length scales. However, due to the inherent complexity of these disordered hases, the analysis of the ...
Starnini, Michele (Fecha de defensa: 2014-10-24)
The data revolution experienced by social science has revealed complex patterns of interactions in human dynamics, such as the heterogeneity and burstiness of social contacts. The recently uncovered temporal dimension of ...
Renedo Rouco, Isabel (Fecha de defensa: 2014-11-13)
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. ...
Andujar Moreno, Rabindranath (Fecha de defensa: 2015-02-03)
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 ...
López Alonso, José Manuel (Fecha de defensa: 2015-02-05)
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 ...
Macía Rey, Adrián (Fecha de defensa: 2015-02-13)
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 ...
Deza, Juan Ignacio (Fecha de defensa: 2015-02-26)
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 ...
Mazón, Jordi (Fecha de defensa: 2015-04-21)
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 ...
Aznar Siguan, Gabriela (Fecha de defensa: 2015-04-30)
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 ...
Tirabassi, Giulio (Fecha de defensa: 2015-06-05)
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 ...
