  • Penya-Alba, Toni (Date of defense: 16-12-2014)
    Supply chain formation involves determining the participants and the exchange of goods within a production network. Today’s companies operate autonomously, making local decisions, and coordinating ...
  • Almajano, Pablo (Date of defense: 17-10-2014)
    The blending of digital technologies, such as artificial intelligence, interactive systems, 3D interfaces and the Internet is enabling new services for users. In particular, Hybrid Structured 3D Virtual Environments (VE) ...
  • Romero, Adriana (Date of defense: 02-10-2015)
    Deep learning has recently been enjoying an increasing popularity due to its success in solving challenging tasks. In particular, deep learning has proven to be effective in a large variety of computer vision tasks, such ...
  • Agora, Elona (Date of defense: 13-07-2012)
    The main goal of this thesis is to characterize the weak-type (resp. strong-type) boundedness of the Hilbert transform H on weighted Lorentz spaces Λpu(w). The characterization is given in terms of some geometric ...
  • Silvestre Albero, María Pilar (Date of defense: 08-02-2012)
    The first part of the thesis is devoted to the analysis on a capacity space, with capacities as substitutes of measures in the study of function spaces. The goal is to extend to the associated function lattices some aspects ...
  • Canadell Cano, Marta (Date of defense: 04-07-2014)
    The subject of the theory of Dynamical Systems is the evolution of systems with respect to time. Hence, it has many applications to other areas of science, such as Physics, Biology, Economics, etc. and it also has interactions ...
  • Taixés i Ventosa, Jordi (Date of defense: 22-09-2011)
    Newton's method associated to a complex holomorphic function f is defined by the dynamical system Nf(z) = z – f(z) / f'(z). As a root-finding algorithm, a natural question is to understand the dynamics of Nf about its fixed ...
  • Miralles Barrachina, Felip (Date of defense: 22-04-2016)
    Our healthcare systems are facing sustainability challenges caused by a demographic shift with ageing, chronicity and disability growing in our society. A novel healthcare paradigm should be founded on 4P medicine: Preventive, ...
  • Alberti, Marina (Date of defense: 21-02-2013)
    In this thesis, several methods for the automatic analysis of Intravascular Ultrasound (IVUS) sequences are presented, aimed at assisting physicians in the diagnosis, the assessment of the intervention and the monitoring ...
  • Domingo Salazar, Carlos (Date of defense: 07-04-2016)
    In this thesis, we study different variants of Rubio de Francia’s extrapolation that allow us to obtain estimates near L1. This theory is subsequently applied to deduce enpoint boundedness for the Bochner-Riesz operator ...
  • Gutiérrez i Serrés, Pere
    La memòria recull contribucions a diversos aspectes del problema de l'estabilitat en sistemes hamiltonians quasi-integrables. Aquests aspectes inclouen resultats d'estabilitat efectiva, que comporten el confinament de ...
  • Bosch Gual, Miquel
    L'objectiu del treball és mostrar que alguns aspectes de certs sistemes dinàmics discrets bidimensionals poden ser estudiats mitjançant sistemes de dimensió 1 que corresponen a casos particulars o simplificacions. Els tres ...
  • Ripoll i Missé, Jordi
    In this Thesis we address the study of some non-linear evolution equations (e.g. pde's) modelling the dynamics of sexually-reproducing structured populations, with special emphasis on biological evolution driven by natural ...
  • Puertas i Prats, Eloi (Date of defense: 04-11-2014)
    Over the past few decades, machine learning (ML) algorithms have become a very useful tool in tasks where designing and programming explicit, rule-based algorithms are infeasible. Some examples of applications ...
  • Reyes Estany, Miguel (Date of defense: 27-02-2017)
    The visual analysis of humans is one of the most active research topics in Computer Vision. Several approaches for body pose recovery have been recently presented, allowing for better generalization of gesture recognition ...
  • Carro Rossell, María Jesús
    El primer resultado de interpolación de operadores data del año 1911 y es debido a I. Schur. Dos años más tarde, Young prueba un resultado del mismo tipo referente a espacios Lp y a un operador L La extensión de estos ...
  • Tatjer i Montaña, Joan Carles
    It is known that for the study of continuous dynamical systems the discret case plays an important role because, with it we can study the continuous one by using the Poincaré return map. In the discret case we can distinguish ...
  • Bautista Martín, Miguel Ángel (Date of defense: 11-02-2016)
    Real life is full of multi-class decision tasks. In the Pattern Recognition field, several method- ologies have been proposed to deal with binary problems obtaining satisfying results in terms of performance. However, the ...
  • Congost Iglesias, Maria Assumpta
    En una primera part s'estudien els conjunts de mesures que prenen valors en un grup reticualt, per a les quals la T-aditivitat es defineix a partir de l'estructura ordenada. L'estudi realitzat a partir de les propietats ...
  • Ortega Aramburu, Joaquín Mª
    Esta memoria recoge algunos de los puntos fundamentales e inéditos que han aparecido al iniciar un estudio sobre los métodos espectrales en Análisis y, en particular, sobre los anillos y estructuras diferenciables. Dicho ...
