Application of dynamical system methods to galactic dynamics : from warps to double bars
(Universitat Politècnica de Catalunya, 2015-06-29)
Tesi
Accés obertMost galaxies have a warped shape when they are seen from an edge-on point of view. In this work we apply dynamical system methods to find an explanation of this phenomenon that agrees with its abundance among galaxies, ... -
Astrophysical parameter determination using chaotic orbital regions
(Universitat Politècnica de Catalunya, 2018-02-27)
Projecte Final de Màster Oficial
Accés obertThe goal of this thesis is to show that chaotic orbits of a dynamical system are advantageous (compared with regularnes) to determine the characteristic parameters of the system, and to give an estimate about the behaviour ... -
Commodity valoration and its derivatives

Projecte Final de Màster Oficial
Accés obertThis thesis contains a methodology whose aim is to compute trajectories describing natural motion of the phase space in a neighborhood of Libtation points and stable/unstable manifolds which correspond to these orbits in ... -
Contributions to Libration Orbit Mission Design using Hyperbolic Invariant Manifolds
(Universitat Politècnica de Catalunya, 2007-07-24)
Tesi
Accés obertAquesta tesi doctoral està emmarcada en el camp de l'astrodinàmica. Presenta solucions a problemes identificats en el disseny de missions que utilitzen òrbites entorn dels punts de libració, fent servir la teoria de sistemes ... -
Development of Models for the Equations of Motion in the Solar System: Implementations and Applications
(Universitat Politècnica de Catalunya, 2014-07-22)
Projecte Final de Màster Oficial
Accés obertThe purpose of this MS-Thesis is to develop suitable semi-analytical quasiperiodic models for the equations of motion in the solar system, in the sense that the models obtained are quasiperiodic pertubations of the restricted ... -
Generació d'escenaris en finances quantitatives
(Universitat Politècnica de Catalunya, 2015-07)
Treball Final de Grau
Accés restringit per decisió de l'autorEn aquest treball es tracta la generació d'escenaris dins de l'àmbit financer. S'utilitza aquesta tècnica amb dos objectius diferents: valoració de productes i optimització de carteres. En la primera part s'estudia com es ... -
Haar Wavelets-Based Methods for Credit Risk Portfolio Modeling
(Universitat Politècnica de Catalunya, 2011-11-24)
Tesi
Accés obertIn this dissertation we have investigated the credit risk measurement of a credit portfolio by means of the wavelets theory. Banks became subject to regulatory capital requirements under Basel Accords and also to the ... -
In-plane station keeping based on a shift of line of apsides strategy
(Universitat Politècnica de Catalunya, 2006-02-27)
Projecte/Treball Final de Carrera
Accés obertIn the last years, the design of the new spatial missions in several study fields require of higher and more demanding levels of flexibility, autonomy, accuracy and resolution. The achievement of these values implies the ... -

Novel consensus strategies applied to spacecraft formation flight
(Universitat Politècnica de Catalunya, 2017-09-04)
Tesi
Accés obertIn this thesis we consider the problem of developing distributed control strategies for spacecraft formation flying. In light of possible interferometric applications, the study is conducted in two different contexts: ... -
Obtaining gravitational models from planetary ephemeris
(Universitat Politècnica de Catalunya, 2012-03)
Projecte Final de Màster Oficial
Accés obertEphemerides describe the position and velocity of a celestial object as a function of time. The ephemerides data are obtained by solving the fundamental equations of motion of the body, which is obtained by applying the ... -
Precessing models and eventual links with galaxy warps
(Universitat Politècnica de Catalunya, 2010-11)
Projecte Final de Màster Oficial
Accés obertThe Restricted Three Body problem is a basic model in celestial mechanics and it has been extensively used in the design of some spatial missions. Sometimes, the designers of these missions consider other similar models ... -
