  • Homoclinic billiard orbits inside symmetrically perturbed ellipsoids 

    Delshams Valdés, Amadeu; Fedorov, Yuri; Ramírez Ros, Rafael (2000)
    Article
    Open Access
    The billiard motion inside an ellipsoid of ${\bf R}^{3}$ is completely integrable. If the ellipsoid is not of revolution, there are many orbits bi-asymptotic to its major axis. The set of bi-asymptotic orbits is described ...
  • Homoclinic orbits of twist maps and billiards 

    Delshams Valdés, Amadeu; Ramírez Ros, Rafael (1997)
    Article
    Open Access
    The splitting of separatrices for hyperbolic fixed points of twist maps with $d$ degrees of freedom is studied through a real-valued function, called the Melnikov potential. Its non-degenerate critical points are associated ...
  • Homoclinic orbits to invariant tori in Hamiltonian systems 

    Delshams Valdés, Amadeu; Gutiérrez Serrés, Pere (1998)
    Article
    Open Access
    We consider a perturbation of an integrable Hamiltonian system which possesses invariant tori with coincident whiskers (like some rotators and a pendulum). Our goal is to measure the splitting distance between the perturbed ...
  • Homoclinic orbits to invariant tori near a homoclinic orbit to center-center-saddle equilibrium

    Article
    Open Access
    We consider a perturbation of an integrable Hamiltonian vector field with three degrees of freedom with a center–center–saddle equilibrium having a homoclinic orbit or loop. With the help of a Poincaré map (chosen based ...
  • Homoclinic phenomena in conservative systems 

    Gonchenko, Marina (Universitat Politècnica de Catalunya, 2013-04-29)
    Doctoral thesis
    Open Access
    The goal of this thesis is the study of homoclinic orbits in conservative systems (area-preserving maps and Hamiltonian systems). We consider homoclinic (bi-asymptotic) orbits either to saddle periodic orbits or to whiskered ...
  • Homodyne laser radar system for surface displacement monitoring

    Article
    Open Access
    A prototype of a homodyne laser radar system for surface displacement monitoring using the reference beam technique is presented. The prototype is very simple, is easy to align and focus, and is able to measure the velocity ...

    A three—dimensional numerical model was implemented to PFC3D Code to simulate cone penetration test in Ticino sand in a calibration chamber. The model is calibrated using laboratory test results. The full/half/quarter ...
  • Homogeneity properties of hypercubes 

    Ovchinnikov, Sergei (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2007)
    Article
    Open Access
    The paper reviews properties of hypercubes of arbitrary dimension from the metric geometry point of view. It is shown, in particular, that a hypercube is a homogeneous metric space with respect to a class of partial cubes. ...
