A network approach for strapdown inertial kinematic gravimetry 

    Termens Perarnau, Maria Assumpció (Date of defense: 2014-03-07)

    Compared to the conventional ground measurement of gravity, airborne gravimetry is more efficient and cost-effective. Especially, the combination of GPS and INS is known to show very good performances recovering the gravity ...

    Algorithms and Methods for Robust Geodetic kinematic Positioning 

    Talaya López, Julià (Date of defense: 2003-06-27)

    El sistema NAVSTAR/GPS ha desenvolupat un paper molt important en les tècniques de posicionament cinemàtic geodèsiques, especialment en la determinació de la trajectòries per a la orientació de sensors aerotransportats ...

    Application of dynamical system methods to galactic dynamics : from warps to double bars 

    Sánchez Martín, Patricia (Date of defense: 2015-06-29)

    Most 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, ...

    A multisymplectic approach to gravitational theories 

    Gaset Rifà, Jordi (Date of defense: 2018-07-25)

    The theories of gravity are one of the most important topics in theoretical physics and mathematical physics nowadays. The classical formulation of gravity uses the Hilbert-Einstein Lagrangian, which is a singular ...

    Novel consensus strategies applied to spacecraft formation flight 

    Paita, Fabrizio (Date of defense: 2017-09-04)

    In 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: ...

    On the quasiperiodic hamiltonian andronov-hopf bifurcation 

    Pacha Andújar, Juan Ramón (Date of defense: 2002-10-21)

    Aquest treball es situa dintre del marc dels sistemes dinàmics hamiltonians de tres graus de llibertat. Allà considerem famílies d'òrbites periòdiques amb una transició estable-complex inestable: sigui L el paràmetre que ...
