Mesógenos alquiloxicianobifenilos : aspectos teóricos y experimentales en las transiciones de fase SmA-N y N-I
(Universitat Politècnica de Catalunya, 2009-03-11)
Doctoral thesis
Open AccessThe work presented here has been focused, basically, on the study of the SmA-N and N-I phase transitions of a group of liquid crystals, the alkyloxycyanobiphenyls (nOCB), in which, for some of them, as it is the case of ... -
Coupled dynamical processes in bacteria
(Universitat Politècnica de Catalunya, 2015-10-27)
Doctoral thesis
Open AccessThe main object of this Thesis is the study of the dynamical coupling between cellular processes, and how this coupling gives rise to a well-defined behavior in the presence of non-linearities and noise. Cell functioning ... -
First measurement of beta-decay half-lives and neutron emission probabilities in several isotopes beyond N = 126
(Universitat Politècnica de Catalunya, 2015-06-05)
Doctoral thesis
Open AccessIn this work beta-decay half-lives and neutron-emission probability values have been experimentally determined for first time in several nuclei beyond the neutron-shell closure at N=126. To this aim the accelerator complex ... -
Scaling-up methodology : a systematical procedure for qualifying NPP nodalizations. Application to the OECD/NEA ROSA-2 and PKL-2 Counterpart test
(Universitat Politècnica de Catalunya, 2014-11-17)
Doctoral thesis
Open AccessSystem codes along with necessary nodalizations are valuable tools for thermal hydraulic safety analysis. Qualifying both codes and nodalizations is an essential step prior to their use in any significant study involving ... -

(Universitat Politècnica de Catalunya, 2014-06-18)
Doctoral thesis
Open AccessThe aim of this thesis is the study of the dynamics induced by optical feedback in semiconductor lasers. This study aims, on the one hand, to improve our knowledge of stocahstic complex systems, and on the other hand, to ... -
IFMIF accelerator facility RAMI analyses in the engineering design phase
(Universitat Politècnica de Catalunya, 2014-05-09)
Doctoral thesis
Open AccessThe planned International Fusion Materials Irradiation Facility (IFMIF) has the mission to test and qualify materials for future fusion reactors. IFMIF will employ the deuteron-lithium stripping reaction to irradiate the ... -
Colour and technology in historic decorated glazes and glasses
(Universitat Politècnica de Catalunya, 2014-05-09)
Doctoral thesis
Open AccessHistorical decorated glass and glazed ceramics are studied with the object to determine the technology of production and to relate it with the optical properties (colour, shine, opacity). Four different case of study are ... -
Exploiting nonlinearity and noise in optical tweezers and semiconductor lasers : from resonant damping to stochastic logic gates and extreme pulses
(Universitat Politècnica de Catalunya, 2014-02-07)
Doctoral thesis
Open AccessThis thesis is focused on the study of stochastic and nonlinear dynamics in optical systems. First, we study experimentally the dynamics of a Brownian nanometer particle in an optical trap subjected to an external forcing. ... -
Development of a simulation tool for MHD flows under nuclear fusion conditions
(Universitat Politècnica de Catalunya, 2011-12-01)
Doctoral thesis
Open AccessIn Nuclear Fusion Technology, MHD flows can be encountered in liquid metal (LM) breeding blankets, the part of a fusion reactor where tritium, one of the fusion fuels, is to be produced. There are several types of LM ... -
