  • On the central configurations in the spatial 5-body problem with four equal masses
    Alvarez, Martha; Corbera Subirana, Montserrat; Llibre, Jaume (Springer, 2016)
    We analyze the families of central configurations of the spatial 5-body problem with four masses equal to 1 when the fifth mass m varies from 0 to +∞. In particular we continue numerically, taking m as a parameter, the ...
  • On the central configurations of the planar 1 + 3 body problem
    Corbera Subirana, Montserrat; Cors Iglesias, Josep Maria; Llibre, Jaume (Springer, 2011)
    We consider the Newtonian four-body problem in the plane with a dominat mass M. We study the planar central configurations of this problem when the remaining masses are infinitesimal. We obtain two different classes of ...
  • On the existence of bi-pyramidal central configurations of the n + 2-body problem with an n-gon base
    Corbera Subirana, Montserrat; Llibre, Jaume (American Institute of Mathematical Science, 2013)
    Abstract. In this paper we prove the existence of central con gurations of the n + 2{body problem where n equal masses are located at the vertices of a regular n{gon and the remaining 2 masses, which are not necessarily ...
  • On the Existence of Central Configurations of p Nested n-gons
    Corbera Subirana, Montserrat; Delgado, Joaquin; Llibre, Jaume (Springer Verlag, 2009)
    In this paper we prove the existence of central configurations of the pnbody problem where the masses are at the vertices of p nested regular n-gons with a common center for all p ≥ 2 and n ≥ 2. In such configurations ...
  • On the existence of central configurations of p nested regular polyhedra
    Corbera Subirana, Montserrat; Llibre, Jaume (Springer, 2010)
    In this paper we prove, for all p 2, the existence of central configurations of the pn-body problem where the masses are located at the vertices of p nested regular polyhedra having the same number of vertices n and a ...
  • On the Selection of Non-Invasive Methods Based on Speech Analysis Oriented to Automatic Alzheimer Disease Diagnosis
    Lopez-de-Ipiña, Karmele; Alonso, Jesús B.; Travieso, Carlos M.; Solé-Casals, Jordi; Egiraun, Harkaitz; Faundez-Zanuy, Marcos; Ezeiza, Aitzol; Barroso, Nora; Ecay-Torres, Miriam; Martinez-Lage, Pablo; Martinez de Lizardui, Unai (MDPI, 2013)
    The work presented here is part of a larger study to identify novel technologies and biomarkers for early Alzheimer disease (AD) detection and it focuses on evaluating the suitability of a new approach for early AD ...
  • On themechanism of wavelength selection of self-organized shoreline sand waves
    Van den Berg, Niels; Falqués, Albert; Ribas Prats, Francesca; Caballeria, Miquel (Wiley, 2014)
    Sandy shorelines exposed to very oblique wave incidence can be unstable and develop self-organized shoreline sand waves. Different types of models predict the formation of these sand waves with an initially dominant ...
