Testing the initial-final mass relationship of white dwarfs

Catalán Ruiz, Sílvia (Date of defense: 2008-03-03)

White dwarfs are the final remnants of low- and intermediate-mass stars. About 95% of main- sequence stars will end their evolutionary pathways as white dwarfs and, hence, the study of the white dwarf population provides ...

Thermal convection in rotating spherical shells

Garcia Gonzalez, Ferran (Date of defense: 2012-12-01)

The study of thermal convection in rotating spherical geometry is fundamental to explain many geophysical and astrophysical phenomena such as the generation of the magnetic fields, or the differential rotation observed in ...

Time-varying networks approach to social dynamics : from individual to collective behavior

Starnini, Michele (Date of defense: 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 ...

Transient and stochastic dynamics in cellular processes

Rué Queralt, Pau (Date of defense: 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 ...

Transitional periods of the atmospheric boundary layer

Blay Carreras, Estel (Date of defense: 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 ...

Ultracold dipolar gases in optical lattices

Trefzger, Christian (Date of defense: 2010-04-19)

Esta tesis es un trabajo teórico, en el que estudiamos la física de los átomos dipolares bosónicos ultrafríos en retículos ópticos. Éstos gases consisten de átomos o moléculas bosónicas, enfriados bajo la temperatura de ...

Unfolding piecewise-smooth dynamics in a single inductor multiple-output switching converter

Moreno Font, Vanessa (Date of defense: 2009-11-09)

Els convertidors commutats de potència són solucions apropiades per subministrar energia a dispositius electrònics per la seva elevada eficiència i reduït cost. El seu ús extensiu en les últimes dècades ha motivat els ...

Variational mechanics and stochastic methods applied to structural design

Andujar Moreno, Rabindranath (Date of defense: 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 ...

White dwarf dynamical interactions

Aznar Siguan, Gabriela (Date of defense: 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 ...
