    In this paper we present numerical simulations performed prior to the deployment of a real-time seismic buoy in the Alboran Sea (Western Mediterranean), in an active seismic area at 250-300m depth. Due to the inherent ...
  • A stroboscopic control for the confinement of swarms in a spherical domain around the Earth

    Swarms of spacecraft are an idea that has been growing in interest in the last few years. This work focuses on the strategies and costs for the maintenance of a swarm of a large number of spacecraft in a close neighborhood ...

  • Systematic study of the connections between the collinear libration points of a coherent Sun-Earth-Moon restricted four-body model

    A new approach is proposed for the systematic detection and refinement of natural connections between the libration points eml1,2 of the Earth-Moon system and sel1,2 of the Sun-Earth system. It makes use of the Quasi-Bicircular ...
  • Formation flying in space borne artificial magnetic dipole field

    In this paper, we consider a new dynamical scenario in which a constantly charged spacecraft (follower) moves near a leader spacecraft, which follows a circular Keplerian orbit around the Earth and generates a rotating ...

    Let S := {p1, . . . , pn} be a set of n points chosen independently and uniformly at random from the unit square and let M be a positive integer. For every point pi = (xi , yi) in S, let p 0 i = (bMxic, bMyic). Let S 0 := ...
  • Matching points with diametral disks 

    Huemer, Clemens; Pérez-Lantero, Pablo; Seara Ojea, Carlos; Silveira, Rodrigo Ignacio (2017)

    We consider matchings between a set R of red points and a set B of blue points with diametral disks. In other words, for each pair of matched points p ¿ R and q ¿ B, we consider the diametral disk defined by p and q. We ...
  • Equivalences and Black-Box Separations of Matrix Diffie-Hellman Problems 

    Villar Santos, Jorge Luis (Springer, 2017)
    Comunicación de congreso
    Acceso abierto
    In this paper we provide new algebraic tools to study the relationship between different Matrix Diffie-Hellman (MDDH) Problems, which are recently introduced as a natural generalization of the so-called Linear Problem. ...
  • Evaluation of AUV-borne ADCP measurements in different navigation modes

    Most Autonomous Underwater Vehicles (AUVs) mount an Acoustic Doppler Current Profilers (ADCP). Data from this sensor are rarely used in scientific studies due to the complexity of its processing and the lack of validation. ...
  • The connectivity of the flip graph of Hamiltonian paths of the grid graph 

    Duque, Frank; Fabila Monroy, Ruy; Flores Peñazola, David; Hidalgo Toscano, Carlos; Huemer, Clemens (2017)

    Let Gn,m be the grid graph with n columns and m rows. Let Hn,m be the graph whose vertices are the Hamiltonian paths in Gn,m, where two vertices P1 and P2 are adjacent if we can obtain P2 from P1 by deleting an edge in P1 ...
  • A boundary control technique to the string-tip-mass system based on a non-symmetric peak-detector model 

    Acho Zuppa, Leonardo; Pujol Vázquez, Gisela (2017)

    This paper presents a vibration control design to the string-tip-mass system by using a non-symmetric peakdetector mechanism. Previously, this peak-detector system was used as an easy algorithm to mitigate vibration on ...
  • Adaptive predictive control of a base-isolated hysteretic system 

    Ponce de León Puig, Nubia Ilia; Acho Zuppa, Leonardo; Rodellar Benedé, José (2017)
    Texto en actas de congreso
    Acceso restringido por política de la editorial
    This article proposes an adaptive predictive control design technique to mitigate the displacement in a hysteretical base-isolated system seismically perturbed. The obtained predictive control law is based on the ...
