Non-linear fluid dynamics in oscillatory cylindrical cavities
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. ...
Neuronal oscillations: from single-unit activity to emergent dynamics and back
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 ...
Transient and stochastic dynamics in cellular processes
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 ...
Monte Carlo study of quantum phase transitions at zero temperature
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 ...
Dinámica de circuitos de regulación genética en bacterias
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 ...
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 ...
Análisis estadístico y comportamiento fractal de las réplicas sísmicas del Sur de California
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 ...
Hawking radiation in NS5 and little string theory
In this thesis we have focused on semi-classical methods that enables us to obtain non-thermal spectra for the vast majority of black holes. This fact is due to taking into account the backreaction of the metric, when the ...
Modelling the dynamics of large scale shoreline sand waves
Shoreline sand waves are shoreline undulations with a length scale of several kilometres and a time scale of years to decades. They occur on many coasts, migrating in the direction of the dominant littoral drift and they ...
Study of thermal transitions in polymers by a multifrequency modulated DSC technique
Differential Scanning Calorimetry (DSC) is one of the most widely used thermal analysis techniques for the study of transitions and relaxation processes in polymers and also in other materials. It measures the heat flow ...
Path Integral Monte Carlo and Bose-Einstein condensation in quantum fluids and solids
Several microscopic theories point out that Bose-Einstein condensation (BEC), i.e., a macroscopic occupation of the lowest energy single particle state in many-boson systems, may appear also in quantum fluids and solids ...
Multi-dimensional simulations of mixing in classical novae
Classical nova explosions are stellar explosions that take place in close binary systems with an energy release only exceeded by gamma-ray bursts and supernova explosions. Matter from the white dwarf flows through the inner ...
Dynamics in orientationally disordered solids
The key features of dynamics of ultraslowing glass forming systems are their universality in diversity. Its origin is recognized as one of the greatest challenges of condensed matter physics and materials engineering in ...
Bubble and droplet flow phenomena at different gravity levels
Two-phase flows are encountered in a wide range of applications both on-ground and in space. The dynamics of such flows in the absence of gravity is completely different from that in normal gravity due to the absence of ...
Nonlinear frequency conversion under general phase mismatched condition: the role of phase locking and random nonlinear domains
In the field of second harmonic (SH) generation most studies have been concerned with maximizing conversion efficiencies, generally achievable at the phase matching (PM) condition. Outside of the PM the conversion efficiency ...
