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 ...
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 ...
In this dissertation, we show the effectiveness of the exploitation of the Circular Restricted Three - Body Problem (CR3BP) in the Earth - Moon framework. We study the motion of a massless particle under ...
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 ...
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 ...
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 ...
Se consideran familias de difeomorfismos con un punto fijo parabólico para el valor cero del parámetro y un punto fijo hiperbólico para valores mayores que cero que tengan en este caso puntos ...
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 ...
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 ...
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 ...
