    This paper evaluates the behavior of the Microsoft Azure G5 cloud instance type over multiple Data Centers. The purpose is to identify if there are major differences between them and to help the users choose the best option ...
  • Volcanic ash modeling with the online NMMB-MONARCH-ASH v1.0 model: model description, case simulation, and evaluation 

    Marti, Alejandro; Folch, Arnau; Jorba, Oriol; Janjic, Zavisa (European Geosciences Union (EGU), 2017-03-24)
    Article
    Accés obert
    Traditionally, tephra transport and dispersal models have evolved decoupled (offline) from numerical weather prediction models. There is a concern that inconsistencies and shortcomings associated with this coupling strategy ...
  • Wavefield compression for adjoint methods in full-waveform inversion 

    Boehm, Christian; Hanzich, Mauricio; de la Puente, Josep; Fichtner, Andreas (Society of Exploration Geophysicists, 2016-09-13)
    Article
    Accés obert
    Adjoint methods are a key ingredient of gradient-based full-waveform inversion schemes. While being conceptually elegant, they face the challenge of massive memory requirements caused by the opposite time directions of ...
  • Study of the Wall Thermal Condition Effect in a Lean-Premixed Downscaled Can Combustor Using Large-Eddy Simulation 

    Mira, Daniel; Vázquez, Mariano; Houzeaux, Guillaume; Gövert, Simon; Kok, Jim W.B.; Mahiques, E.I.; Panek, Lukasz (American Society of Mechanical Engineers, 2016-06-13)

    The primary purpose of this study is to evaluate the ability of LES, with a turbulent combustion model based on steady flamelets, to predict the flame stabilization mechanisms in an industrial can combustor at full load ...
  • Double-electron ionization driven by inhomogeneous fields 

    Chacón, A.; Ortmann, L.; Cucchietti, F.; Suárez, N.; Pérez-Hernández, J.A.; Ciappina, M.F.; Landsman, A.S.; Lewenstein, M. (Springer International Publishing, 2017-04)
    Article
    Accés restringit per política de l'editorial
    Electron–electron correlation effects play a crucial role in our understanding of sequential (SDI) and non-sequential double ionization (NSDI) mechanisms. Here, we present a theoretical study of NSDI driven by plasmonic-enhanced ...

    In this paper, we evaluate the error criticality of radiation-induced errors on modern High-Performance Computing (HPC) accelerators (Intel Xeon Phi and NVIDIA K40) through a dedicated set of metrics. We show that, as long ...
  • Toward an automatic full-wave inversion: Synthetic study cases 

    Kormann, Jean; Rodriguez, Juan E.; Gutierrez, Natalia; Ferrer, Miguel; Rojas, Otilio; de la Puente, Josep; Hanzich, Mauricio; Cela, Jose M. (Society of Exploration Geophysicists, 2016-12)
    Article
    Accés obert
    Full-waveform inversion (FWI) in seismic scenarios continues to be a complex procedure for subsurface imaging that might require extensive human interaction in terms of model setup, constraints, and data preconditioning. ...
  • Non-linear MHD Simulation s of Pellet Triggered ELMs in JET and ASDEX Upgrade tokamaks 

    Futatani, Shimpei; Pamela, S.; Huijsmans, G.T.A.; Garzotti, L.; Frigione, D.; Loarte, D.; Hoelzl, M.; Lang, P.T.; Kocsis, G.; Orain, F.; Dunne, M.; Lessig, A.; Mantsinen, Mervi; EUROfusion MST1 Team; ASDEX Upgrade Team; JET Contributors (2016-07-08)
    Accés obert
    ITER operation in its high fusion performance DT scenarios relies on the achievement of the H-mode confinement regime, which is expected to lead to the quasi-periodic triggering of ELMs (Edge Localized Modes). ...
  • Modelling third harmonic ion cyclotron acceleration of deuterium beams for JET fusion product studies experiments 

    Schneider, M.; Johnson, T.; Dumont, R.; Eriksson, L.-G.; Giacomelli, L.; Girardo, J.-B.; Hellsten, T.; Khilkevitch, E.; Kiptily, V.G.; Koskela, T.; Mantsinen, M.; Nocente, M.; Salewski, M.; Sharapov, S.E.; Shevelev, A.E.; Jet Contributors (IOP Publishing, 2016-08-24)
