  • A WRF simulation of an episode of contrails covering the entire sky 

    Mazón Bueso, Jordi; Pino González, David (2016-07-20)
    Article
    Accés obert
    On 21 September 2012 the entire sky was covered by contrails over the Gulf of Lyon (NW of the Mediterranean basin). These clouds were well recorded by ground observers as well as by Meteosat imagery. The atmospheric ...
  • Meteorological and hydrological analysis of major floods in NE Iberian Peninsula 

    Pino González, David; Ruiz Bellet, Josep Lluís; Balasch Solanes, Josep Carles; Tuset Mestre, Jordi; Barriendos Valve, Mariano; Mazón Bueso, Jordi; Castelltort, Xavier (Elsevier, 2016-09-30)
    Article
    Accés restringit per política de l'editorial
    This paper analyses the meteorological conditions and the specific peak flows of 24 catastrophic floods that affected NE Iberian Peninsula in the period 1842–2000. We classify these floods according to the affected area, ...
  • On the morphodynamic stability of intertidal environments and the role of vegetation 

    Kakeh Burgada, Nabil; Giovanni, Coco; Marani, Marco (Elsevier, 2016-07-01)
    Article
    Accés restringit per política de l'editorial
    We describe the coupled biotic and abiotic dynamics in intertidal environments using a point model that includes suspended sediment deposition, wave-and current-driven erosion, biofilm sediment stabilization, and sediment ...
  • Natural convection in a horizontal cylinder with axial rotation 

    Sánchez Casals, Odalys de la Caridad; Mercader Calvo, María Isabel; Batiste Boleda, Oriol; Alonso Maleta, María Aránzazu (AMER PHYSICAL SOC, 2016-06-23)
    Article
    Accés obert
    We study the problem of thermal convection in a laterally heated horizontal cylinder rotating about its axis. A cylinder of aspect ratio Gamma = H/2R = 2 containing a small Prandtl number fluid (sigma = 0.01) representative ...
  • Prediction of image partitions using Fourier descriptors: application to segmentation-based coding schemes 

    Marqués Truyol, Francisco; Gasull Llampallas, Antoni (1998-04)
    Article
    Accés obert
    This paper presents a prediction technique for partition sequences. It uses a region-by-region approach that consists of four steps: region parameterization, region prediction, region ordering, and partition creation. The ...
  • Continuation and stability of convective modulated rotating waves in spherical shells 

    García González, Fernando; Net Marcé, Marta; Sánchez Umbría, Juan (2016-01-01)
    Article
    Accés obert
    Modulated rotating waves (MRW), bifurcated from the thermal-Rossby waves that arise at the onset of convection of a fluid contained in a rotating spherical shell, and their stability, are studied. For this purpose, ...
  • Critical torsional modes of convection in rotating fluid spheres at high Taylor numbers 

    Sánchez Umbría, Juan; García González, Fernando; Net Marcé, Marta (2016-02-15)
    Article
    Accés obert
    A numerical study of the onset of convection in rotating internally heated self-gravitating fluid spheres is presented. The exploration of the stability of the conduction state versus the Taylor and Prandtl numbers supplies ...
  • Bone tissue properties measurement by reference point indentation in glucocorticoid-induced osteoporosis 

    Mellibovsky, Leonardo; Prieto Alhambra, Daniel; Mellibovsky Elstein, Fernando; Gueerri Fernandez, Roberto; Nogués, Xavier; Randall, Connor; Hansma, Paul K.; Diez Perez, Adolfo (2015-09-01)
    Article
    Accés obert
    Glucocorticoids, widely used in inflammatory disorders, rapidly increase bone fragility and, therefore, fracture risk. However, common bone densitometry measurements are not sensitive enough to detect these changes. Moreover, ...
  • El canvi climàtic a través dels informes de l'IPCC (1990-2014) 

    Mazón Bueso, Jordi (Càtedra UNESCO en Sostenibilitat., 2016-01-20)
    Article
    Accés obert
    Des de que l’any 1990 es va publicar el primer informe del Panell Intergovernamental del Canvi Climàtic (en anglès IPCC) quatre més han aparegut (els anys 1995, 2001, 2007 i 2014), els quals ens donen una visió de ...
  • Conductive and convective heat transfer in fluid flows between differentially heated and rotating cylinders 

    López, José M.; Marqués Truyol, Francisco; Àvila Cañellas, Marc (2015-11-01)
    Article
    Accés obert
    The flow of fluid confined between a heated rotating cylinder and a cooled stationary cylinder is a canonical experiment for the study of heat transfer in engineering. The theoretical treatment of this system is greatly ...
