    In this article, a new concept for SBAS integrity validation is presented. The proposed concept is a modification of the well known Stanford diagram [2], where a 2D histogram shows the relationship of position errors against ...
  • Towards a direct numerical simulation of a lifted CH4-air diffusion flame 

    Ventosa Molina, Jordi; Lehmkuhl Barba, Oriol; Pérez Segarra, Carlos David; Oliva Llena, Asensio (Begell House, 2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The near field jet of a self-igniting methane-air diffusion jet flame is studied by means of Direct Numerical Simulation (DNS) and a Flamelet/Progress-Variable (FPV) model to include detailed chemistry. Hence, all flow and ...
  • Simulations and analysis of beam quality improvement in spatially modulated broad area edge-emitting devices 

    Radziunas, Mindaugas; Herrero Simon, Ramon; Botey Cumella, Muriel; Staliunas, Kestutis (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2014)

  • Analysis of nonlinear and non-smooth dynamics of a self-oscillating series resonant inverter 

    Benadero García-Morato, Luis; Ponce Núñez, Enrique; El Aroudi, Abdelali (2017)
    Text en actes de congrés
    Accés obert
    In this paper, the dynamics of a dc-ac resonant self-oscillating LC series inverter is analyzed from the point of view of piecewise smooth dynamical systems. Our system is defined by two symmetric configurations and its ...
  • La gestión de la calidad: algunas reflexiones sobre los procesos de calidad que se implantan en los centros docentes universitarios

  • Local wind regime characterization and modelling for wind energy optimization, applying statistical and geostatistical methods 

    Hervada Sala, Carme; Jarauta Bragulat, Eusebio; Buenestado Caballero, Pablo (2010)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    In wind energy production through wind turbines, one of the elements that have been stated as much relevant to optimize energy production is the knowledge of the local wind regime in the area in which the wind farm is ...
  • On multi-scale structural topology optimization and material design 

    Ferrer Ferré, Àlex; Cante Terán, Juan Carlos; Oliver Olivella, Xavier (Associação Portuguesa de Mecânica Teórica, Aplicada e Computacional (APMTAC), 2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Computational material design has gained considerable interest, along the last years, in the computational mechanics community. Although most of the current approaches focus on one-scale structural optimization, this work ...
  • Large eddy simulation of hydrogen autoignition in a preheated turbulent co-flow 

    Muela Castro, Jordi; Lehmkuhl Barba, Oriol; Oliva Llena, Asensio; Ventosa Molina, Jordi (2013)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The autoignition process of a hydrogen jet into a preheated turbulent air stream is numerically studied. A Progress-variable (PV) model with the turbulence-chemistry interactions modelled using a Presumed Conditional Moment ...
