Rodríguez López, Salvador (Data de defensa: 2008-04-07)
In the early 1970 fs, R. Coifman and G. Weiss, generalizing the techniques introduced by A. Calderon, developed a method for transferring abstract convolution type operators, defined on general topological ...
Agora, Elona (Data de defensa: 2012-07-13)
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 ...
Simon i Estrada, Sergi (Data de defensa: 2007-07-09)
In this thesis, we present a proof of the meromorphic non-integrability for some problems arising from Celestial Mechanics, as well as a new necessary condition for partial integrability in a wider ...
Domingo Salazar, Carlos (Data de defensa: 2016-04-07)
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 ...
Miralles Barrachina, Felip (Data de defensa: 2016-04-22)
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 ...
Pridhnani, Bharti (Data de defensa: 2011-09-09)
This monograph is structured in four chapters. In Chapter 1, we present the context of our problem and the main results proved in this work. We describe the asymptotic behaviour of the reproducing ...
Ripoll i Missé, Jordi (Data de defensa: 2005-10-05)
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 ...
Tatjer i Montaña, Joan Carles (Data de defensa: 1990-03-01)
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 ...
Reyes Estany, Miguel (Data de defensa: 2017-02-27)
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 ...
Silvestre Albero, María Pilar (Data de defensa: 2012-02-08)
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 ...
