  • The influence of an increase of the Mediterranean Sea Surface Temperature on two nocturnal offshore rainbands: a numerical experiment 

    Mazón Bueso, Jordi; Pino González, David (2017-03-18)
    Article
    Accés obert
    Using the Weather Research and Forecasting (WRF) – Advanced Research WRF (ARW) mesoscale model (WRF–ARW), we investigate how two nocturnal offshore rainbands occurring in the Mediterranean basin are modified in a warmer ...
  • Emergence of spatio-temporal dynamics from exact coherent solutions in pipe flow 

    Ritter, Paul; Mellibovsky Elstein, Fernando; Avila Cañellas, Marc (2016-08-12)
    Article
    Accés obert
    Turbulent-laminar patterns are ubiquitous near transition in wall-bounded shear flows. Despite recent progress in describing their dynamics in analogy to non-equilibrium phase transitions, there is no theory explaining ...
  • On regular rotating black holes 

    Torres Herrera, Ramon; Fayos Vallés, Francisco (2017-01-01)
    Article
    Accés restringit per política de l'editorial
    Different proposals for regular rotating black hole spacetimes have appeared recently in the literature. However, a rigorous analysis and proof of the regularity of this kind of spacetimes is still lacking. In this note ...
  • Using archives of past floods to estimate future flood hazards 

    Swierczynski, Tina; Ionita, Monica; Pino González, David (2017-01-13)
    Article
    Accés obert
    Worldwide, floods cause greater economic damage and loss of human life than any other type of natural disaster. We urgently need better assessments of flood hazards to reduce the societal impact of extreme floods caused ...
  • Inertial waves in rapidly rotating flows: a dynamical systems perspective 

    López Moscat, Juan Manuel; Marqués Truyol, Francisco (2016-11-02)
    Article
    Accés restringit per política de l'editorial
    An overview of recent developments in a wide variety of enclosed rapidly rotating flows is presented. Highlighted is the interplay between inertial waves, which have been predicted from linear inviscid considerations, and ...
  • Flexible rod design for educational wind balance 

    Raush Alviach, Gustavo Adolfo; Castilla López, Roberto; Gámez Montero, Pedro Javier; Wojciechowski, Jakub; Codina Macià, Esteban (2016-03-07)
    Article
    Accés obert
    This article provides a technical description of a flexible hinge for wind tunnel rigs. For academic purposes, the device was integrated into several rod flexures to build a home-made external wind balance system. The ...
  • Periodic orbits in tall laterally heated rectangular cavities 

    Net Marcé, Marta; Sánchez Umbría, Juan (2017-02-02)
    Article
    Accés obert
    This study elucidates the origin of the multiplicity of stable oscillatory flows detected by time integration in tall rectangular cavities heated from the side. By using continuation techniques for periodic orbits, it is ...
  • Maxwell equations in the Debye potential formalism 

    Fayos Vallés, Francisco; Llanta Salleras, Estanislao; Llosa, J (1985-02-01)
    Article
    Accés obert
    The authors propose a method for computing the electromagnetic test-field created by a given distribution of charges and currents using the Debye potential formalism in curved space-times. This framework has been applied ...
  • Nonlinear and detuning effects of the nutation angle in precessionally-forced rotating cylinder flow 

    Lopez Moscat, Juan Manuel; Marqués Truyol, Francisco (2016-06-16)
    Article
    Accés obert
    The flow in a rapidly rotating cylinder forced to precess through a nutation angle a is investigated numerically, keeping all parameters constant except a, and tuned to a triadic resonance at a = 1º. When increasing a, ...
  • An exactly solvable model in P.R.M.: quantization. II 

    Iranzo Fernández, Vicente; Llosa, J; Marqués Truyol, Francisco; Molina, A (1984-01)
    Article
    Accés obert
    The quantization of a priori hamiltonian predictive systems is studied. It is applied to quantize the family of N-particle relativistic models presented in ref. 1. The relativistic two-particle oscillator is studied in ...
