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

      Álvarez Lacalle, Enrique; Miranda, Jose. A; Dias, Eduardo; Carvalho, Marcio (2012)
      Text en actes de congrés
      Accés obert
      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 ...

      Text en actes de congrés
      Accés restringit per decisió de l'autor
      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)
      Comunicació de congrés
      Accés obert
      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)
      Comunicació de congrés
      Accés obert
      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)
      Text en actes de congrés
      Accés obert
      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)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      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 ...
