    Article
    Accés obert
    We follow the mass expelled during the WD-WD merger process in a particular case of the double-degenerate (DD) scenario for Type Ia supernovae (SNe Ia), and find that the interaction of the SN ejecta with the resulting ...

  • Constraint algorithm for extremals in optimal control problems 

    Barbero Liñán, María; Muñoz Lecanda, Miguel Carlos (2007-07-27)
    Article
    Accés obert
    A characterization of different kinds of extremals of optimal control problems is given if we take an open control set. A well known constraint algorithm for implicit differential equations is adapted to the study of ...

    Working paper
    Accés obert
    The k-symplectic formulation of field theories is especially simple, since only tangent and cotangent bundles are needed in its description. Its defining elements show a close relationship with those in the symplectic ...

    Accés restringit per política de l'editorial
    Accessing the raw data of spaceborne SAR systems is not always possible to refocus blurred SAR signatures of vessels. Instead, the single-look complex (SLC) data is usually more available, but since the vessel motion can ...
