  • Inhibition of viscous fluid fingering: A variational scheme for optimal flow rates 

    Álvarez Lacalle, Enrique; Miranda, Jose. A; Dias, Eduardo; Carvalho, Marcio (2012)
    Conference report
    Open Access
    Conventional viscous fingering flow in radial Hele-Shaw cells employs a constant injection rate, resulting in the emergence of branched interfacial shapes. The search for mechanisms to prevent the development of these ...
  • Optimization of the tantalum ore production by control the milling process 

    Alfonso Abella, María Pura; Oliva Moncunill, Josep; Álvarez Rodríguez, Beatriz; Jorge Sánchez, Juan; Sanmiquel Pera, Lluís; Parcerisa Duocastella, David; Tomasa Guix, Oriol; Calvo Torralba, Daniel; Guasch Cascallo, Eduard; Felipe Blanch, José Juan de; Anticoi Sudzuki, Hernán Francisco; García-Vallès, Maite (2015)
    Conference report
    Open Access
    Tantalum is a strategic metal with multiple applications in the new technologies. Tantalum deposits are scarce in EU. Thus, more efficient extracting processes are necessary to contribute to major European independency on ...

  • Novel ionospheric activity indicator specifically tailored for GNSS users 

    Sanz Subirana, Jaume; Juan Zornoza, José Miguel; González Casado, Guillermo; Prieto Cerdeira, Roberto; Schlüter, S.; Orús Pérez, Raul (The Institute of Navigation, 2014)
    Conference report
    Restricted access - author's decision
    This work introduces a novel ionospheric activity indicator useful for identifying disturbed periods affecting performance for GNSS users, at regional level. This indicator is based in the “Along Arc TEC Rate (AATR) and ...
  • Characterization of thermal insulation materials developed with crop wastes and natural binders 

    Lacasta Palacio, Ana María; Palumbo Fernández, Mariana; Navarro Ezquerra, Antonia; Avellaneda Díaz-Grande, Jaume (2014)
    Conference lecture
    Open Access
    This paper seeks to discuss the possibility of developing insulation materials for the construction sector made of non-industrial crop wastes and natural binders. Three different crop wastes widely available in Spain, ...
  • An intercomparison of mesoscale simulations during the Boundary Layer Late Afternoon and Sunset Turbulence (BLLAST) experimental field campaign 

    Jiménez Cortés, M. Antònia; Angevine, Wayne M.; Bazille, Eric; Couvreux, Fleur; Cuxart Rodamillans, Joan; Pino González, David; Sastre Marugas, Mariano (2014)
    Conference lecture
    Open Access
    The Convective (diurnal, CBL) and Stably stratified (nocturnal, SBL) Boundary Layers over land have been extensively observed and relatively successfully modeled. But the early morning transition, when the CBL emerges from ...
  • Evolution of the turbulence during the afternoon transition of the convective boundary layer: a spectral analysis 

    Darbieu, Clara; Lohou, Fabienne; Lothon, Marie; Couvreux, Fleur; Pino González, David; Durand, Pierre; Blay Carreras, Estel; Vilà Guerau de Arellano, Jordi (American Meteorological Society, 2014)
    Conference report
    Open Access
    The transition from a well-mixed convective boundary layer to a residual layer overlying a stabilized nocturnal layer raises several issues, which remain difficult to address from both modeling and observational perspectives. ...
  • A real-time world-wide ionospheric model for single and multi-frequency precise navigation 

    Rovira Garcia, Adrià; Juan Zornoza, José Miguel; Sanz Subirana, Jaume (The Institute of Navigation, 2014)
    Conference lecture
    Restricted access - publisher's policy
    The ionosphere plays an important role in satellite-based navigation, either in standard navigation, with single frequency mass-market receivers, or in precise navigation, with dual frequency receivers. In this work, the ...
  • Criterios para prácticas de evaluación de calidad. Una propuesta de GRAPA-RIMA 

    Cadenato Matia, Ana María; Martinez, Maria; Amante García, Beatriz; Gallego Fernández, María Isabel; Jordana Barnils, José; Sánchez Robert, Francesc Josep; Farrerons Vidal, Óscar; Isalgué Buxeda, Antonio; Fabregat Fillet, Jaume (Octaedro, 2012)
    Conference report
    Open Access
    El grupo de innovación GRAPA (GRupo de la Evaluación de la Práctica Académica) del proyecto RIMA de la Universitat Politècnica de Catalunya ha elaborado una serie de criterios, en forma de rúbrica, como buenas prácticas ...
  • Numerical-simulation research on building-facade geometry and its effect on fire propagation in wooden facades 

    Lacasta Palacio, Ana María; Giraldo, Pilar; Avellaneda Diaz-Grande, Jaime; Burgos Leiva, Camila (2014)
    Conference report
    Open Access
    Fire protection is a very important requirement in the facade of a building. When there is a fire in a building, the facade can be one of the quickest spreading pathways, regardless of the material of which it is constructed. ...
  • Two computational approaches for the simulation of fluid problems in rotating spherical shells 

    García González, Fernando; Dormy, Emmanuel; Sánchez Umbría, Juan; Net Marcé, Marta (2014)
    Conference lecture
    Open Access
    Many geophysical and astrophysical phenomena such as magnetic fields generation, or the differential rotation observed in the atmospheres of the major planets are studied by means of numerical simulations of the Navier-Stokes ...
