Experimental and numerical study of the symbolic dynamics of modulated semiconductor lasers with optical feedback
(Universitat Politècnica de Catalunya, 2015-07-10)
Tesi
Accés obertThe 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
(Universitat Politècnica de Catalunya, 2015-10-07)
Tesi
Accés obertDynamic 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 ... -
Improvement of corrosion and mechanical properties of amorphous steels by microalloying and nanocrystallization
(Universitat Politècnica de Catalunya, 2015-09-14)
Tesi
Accés obertLos aceros amorfos que contienen cantidades óptimas de cromo son muy atractivos para aplicaciones prácticas debido a su comportamiento frente a la corrosion. Estas aleaciones tienen extraordinarias propiedades de resistencia ... -
Convección natural en cavidades tridimensionales
(Universitat Politècnica de Catalunya, 2015-11-10)
Tesi
Accés obertThe 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
(Universitat Politècnica de Catalunya, 2015-07-22)
Tesi
Accés obertThe 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
(Universitat Politècnica de Catalunya, 2015-07-17)
Tesi
Accés obertThiolate 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
(Universitat Politècnica de Catalunya, 2015-06-05)
Tesi
Accés obertEn 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
(Universitat Politècnica de Catalunya, 2015-04-21)
Tesi
Accés obertThe 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
(Universitat Politècnica de Catalunya, 2015-04-30)
Tesi
Accés obertMerging 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
(Universitat Politècnica de Catalunya, 2015-02-13)
Tesi
Accés obertA 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
(Universitat Politècnica de Catalunya, 2015-02-26)
Tesi
Accés obertThis 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
(Universitat Politècnica de Catalunya, 2015-02-05)
Tesi
Accés obertDespite 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 ...
