‘State narrative’ construction on Twitter. A case study around news stories on LGTB issues in Russia
Aquesta tesi doctoral combina la teoria de la "narrativa estatal estratègica" amb els estudis de comunicació, les relacions internacionals i la recerca sobre xarxes socials. Pren com a estudi de cas la construcció i ...
Static and dynamic global stiffness analysis for automotive pre-design
In order to be worldwide competitive, the automotive industry is constantly challenged to produce higher quality vehicles in the shortest time possible and with the minimum costs of production. Most of the problems with ...
Static structural system identification using observability method
During the construction and operation stages of structures, various factors lead to irreversible degradation that could affect the normal use and the public safety of these structures. In recent years, it has been common ...
Station keeping analysis and design for new floating offshore wind turbines
In the framework of the reduction of the emissions of greenhouse gases, FOWT will be the technology that will exploit the wind resources in deep seas. In order to achieve a commercial deployment of this technology, a cost ...
Statistical analysis and design of subthreshold operation memories
This thesis presents novel methods based on a combination of well-known statistical techniques for faster estimation of memory yield and their application in the design of energy-efficient subthreshold memories. The emergence ...
Statistical analysis and plasmonic effects to extend the use of Raman spectroscopy in biochemistry
Since its discovery in 1928, Raman spectroscopy (RS) has produced a revolution in the fields of analytical chemistry and molecular detection. Thanks to the latest technical advances, the expectations of the applicability ...
Statistical analysis of neural correlates in decision-making
We investigated the neuronal processes which occur during a decision- making task based on a perceptual classi cation judgment. For this purpose we have analysed three di erent experimental paradigms (somatosensory, ...
Statistical and empirical issues in the analysis of duration data
Aquesta tesi s'emmarca en l'anàlisi de la supervivència. A la primera part es proposa una metodologia per estimar els coeficients d'un model lineal amb censura a la resposta i error de mesura a les covariants. Es proposa ...
Statistical and thermodynamical properties of DNA unzipping experiments with optical tweezers
[eng] Molecular biophysics is a scientific discipline that studies biomolecules. This discipline has experienced a revolution thanks to the development of single- molecule techniques. These techniques allows us to obtain ...
Statistical Applications in Geographical Health Studies
Aquesta tesi està formada per dues parts relacionades amb l'estudi de la salut d'una regió geogràfica dividida en un conjunt de zones (àrees petites). La primera part es basa en un estudi amb informació de salut agregada ...
Statistical atlases of cardiac motion and deformation for the characterization of CRT responders
The definition of optimal selection criteria for maximizing the response rate to Cardiac Resynchronization Therapy (CRT) is still an issue under active debate. Recent clinical approaches propose a classification of patients ...
Statistical detection of tidal streams generated by globular clusters and their application to measure the axis ratio of the Milky Way dark matter halo
In this thesis we have presented a new method to search for tidal streams generated by globular clusters in the Gaia catalogue. This statistical method is based on the maximum likelihood technique to distinguish stream ...
Statistical distribution of common audio features : encounters in a heavy-tailed universe
In the last few years some Music Information Retrieval (MIR) researchers have spotted important drawbacks in applying standard successful-in-monophonic algorithms to polyphonic music classification and similarity assessment. ...
Statistical framework for terminating evolutionary algorithms at their steady state
El objetivo de esta tesis es de determinar la calidad de las condiciones de parada existentes para terminar un Algoritmo Evolutivo cuando llegue a su un estado estacionario. Un Algoritmo Evolutivo es una técnica iterativa ...
Statistical inference in bipartite networks applied to social dilemmas and human microbial systems
La predicció de ‘links’ o enllaços en xarxes complexes és un problema de molta importància, degut a la utilitat pràctica que implica. La capacitat de predir enllaços correctament en una xarxa és, però, també una conseqüència ...
Statistical learning methods for energy assessment in buildings with applications at different geographic levels
El sector de l'edificació, sense incloure la seva indústria, és un dels principals focus de consum energètic del món. Suposa al voltant d'un 30% del total d'energia final consumida mundialment. A més, les seves emissions ...
Statistical Local Appearance Models for Object Recognition
Durant els últims anys, hi ha hagut un interès creixent en les tècniques de reconeixement d'objectes basades en imatges, on cadascuna de les quals es correspon a una aparença particular de l'objecte. Aquestes tècniques que ...
Statistical Mechanics of Superparamagnetic Colloidal Dispersions Under Magnetic Fields
Les dispersions col·loïdals, un terme encunyat pel científic escocès Thomas Graham el 1861, han estat objecte d’interès en diferents àrees científiques durant més d'un segle. Una dispersió col·loïdal es caracteritza per ...
Statistical methods and software for clinical trials with binary and survival endpoints : efficiency, sample size and two-sample comparison
Defining the scientific question is the starting point for any clinical study. However, even though the main objective is generally clear, how this is addressed is not usually straightforward. Clinical studies very often ...
