  • New parallel method for adjacent disconnected unstructured 3D meshes 

    Muela Castro, Jordi; Martínez Valdivieso, Daniel; Lehmkuhl Barba, Oriol; Pérez Segarra, Carlos David; Oliva Llena, Asensio (2016-07-14)
    Article
    Accés obert
    A new parallel method for simulations with non-overlapping disconnected mesh domains but adjacent boundaries is presented and studied. This technique allows simulations using 3D unstructured meshes that are independent.
  • Towards high performance robotic computing 

    Camargo Forero, Leonardo; Royo Chic, Pablo; Prats Menéndez, Xavier (2018-09-01)
    Article
    Accés restringit per política de l'editorial
    Embedding a robot with a companion computer is becoming a common practice nowadays. Such computer is installed with an operatingsystem, often a Linux distribution. Moreover, Graphic Processing Units (GPUs) can be embedded ...
  • The inverse-square interaction phase diagram: unitarity in the bosonic ground state 

    Astrakharchik, Grigori; Kryuchkov, P. S.; Kurbakov, I. L.; Lozovik, Yu. E. (Multidisciplinary Digital Publishing Institute (MDPI), 2018-06-08)
    Article
    Accés obert
    Ground-state properties of bosons interacting via inverse square potential (three dimensional Calogero-Sutherland model) are analyzed. A number of quantities scale with the density and can be naturally expressed in units ...
  • PVST, a tool to assess the power to volume scaling distortions associated to code simulations 

    Martínez Quiroga, Víctor Manuel; Freixa Terradas, Jordi; Reventós Puigjaner, Francesc (2018-06-01)
    Article
    Accés restringit per política de l'editorial
    System codes along with necessary nodalizations are valuable tools for thermal hydraulic safety analysis. In order to assess the safety of a particular power plant, in addition to the validation and veri cation of the code, ...
  • Including linear holding in air traffic flow management for flexible delay handling 

    Xu, Yan; Prats Menéndez, Xavier (2017-10)
    Article
    Accés obert
    This paper introduces a strategy to include linear holding into air traffic flow management initiatives, together with the commonly used ground holding and airborne holding measures. In this way, flow management performance ...
  • Sharp acoustic vortex focusing by Fresnel-spiral zone plates 

    Jimenez, Noe; Romero García, Vicenç; Garcia Raffi, Luis Miguel; Staliunas, Kestutis (2018-05-14)
    Article
    Accés restringit per política de l'editorial
    We report the optimal focusing of acoustic vortex beams by using flat lenses based on a Fresnel- spiral diffraction grating. The flat lenses are designed by spiral-shaped Fresnel zone plates composed of one or several arms. ...
  • Self-induced Faraday instability laser 

    Perego, A.M.; Smirnov, Sergey V.; Staliunas, Kestutis; Churkin, D.V.; Wabnitz, Stefan (American Institute of Physics (AIP), 2018-05-22)
    Article
    Accés obert
    We predict the onset of self-induced parametric or Faraday instabilities in a laser, spontaneously caused by the presence of pump depletion, which leads to a periodic gain landscape for light propagating in the cavity. As ...
  • On the static strength of aluminium and carbon fibre aircraft lap joint repairs 

    Pitta, Siddharth; de la Mora Carles, Victor; Roure Fernández, Francisco; Crespo Artiaga, Daniel; Rojas Gregorio, José Ignacio (2018-10-01)
    Article
    Accés restringit per política de l'editorial
    The behaviour of various aircraft lap joint repair configurations is investigated experimentally and numerically under static loading. The lap joints consist of aluminium alloy (AA) 2024-T3 substrates repaired with twin ...
  • Peering into the dark side: Magnesium lines establish a massive neutron star in PSR J2215+5135 

    Linares Alegret, Manuel; Shahbaz, T.; Casares, Jorge (Institute of Physics (IOP), 2018-05-20)
    Article
    Accés obert
    New millisecond pulsars (MSPs) in compact binaries provide a good opportunity to search for the most massive neutron stars. Their main-sequence companion stars are often strongly irradiated by the pulsar, displacing the ...
  • Sub-threshold signal encoding in coupled FitzHugh-Nagumo neurons 

    Masoliver Vila, Maria; Masoller Alonso, Cristina (Nature, 2018-05-29)
    Article
    Accés obert
    Despite intensive research, the mechanisms underlying the neural code remain poorly understood. Recent work has focused on the response of a single neuron to a weak, sub-threshold periodic signal. By simulating the stochastic ...
  • Climb, cruise, and descent speed reduction for airborne delay without extra fuel 

    Xu, Yan; Dalmau Codina, Ramon; Prats Menéndez, Xavier (2018-05-01)
    Article
    Accés obert
    In the majority of situations, air traffic flow management (ATFM) regulations are issued due to weather-related capacity reductions. Considering the uncertainties in weather prediction and other unforeseen factors, ATFM ...
  • Distributing the global carbon budget with climate justice criteria 

    Alcaraz Sendra, Olga; Buenestado Caballero, Pablo; Escribano Rodríguez de Robles, Beatriz; Sureda Carbonell, Bàrbara; Turon Florenza, Albert; Xercavins, Josep (2018-05-28)
    Article
    Accés restringit per política de l'editorial
    In this paper, a model for the distribution of the Global Carbon Budget between the countries of the world is presented. The model is based on the criteria of equity while also taking into account the different historical ...
