  • Challenges in the extrapolation from DD to DT plasmas: experimental analysis and theory based predictions for JET-DT 

    Garcia, J.; Challis, C.; Gallart, D.; Garzotti, L.; Görler, T.; King, D.; Mantsinen, Mervi; Jet Contributors (IOP Publishing, 2016-10-27)
    Article
    Accés obert
    A strong modelling program has been started in support of the future JET-DT campaign with the aim of guiding experiments in deuterium (D) towards maximizing fusion energy production in Deuterium–Tritium (DT). Some of the ...
  • Heat loss prediction of a confined premixed jet flame using a conjugate heat transfer approach 

    Gövert, S.; Mira, Daniel; Zavala-Ake, M.; Kok, J.B.W.; Vázquez, Mariano; Houzeaux, Guillaume (Elsevier, 2017-04)
    Article
    Accés obert
    The presented work addresses the investigation of the heat loss of a confined turbulent jet flame in a lab-scale combustor using a conjugate-heat transfer approach and large-eddy simulation. The analysis includes the ...
  • Generation of Curved High-order Meshes with Optimal Quality and Geometric Accuracy 

    Ruiz-Girones, Eloi; Sarrate, Josep; Roca, Xevi (Elsevier, 2016)
    Article
    Accés obert
    We present a novel methodology to generate curved high-order meshes featuring optimal mesh quality and geometric accuracy. The proposed technique combines a distortion measure and a geometric Full-size image (<1 K)-disparity ...
  • Representing Urban Geometries for Unstructured Mesh Generation 

    Gargallo-Peiró, Abel; Folch, Arnau; Roca, Xevi (Elsevier, 2016)
    Article
    Accés obert
    We present a robust and automatic method to generate an idealized surface geometry of a city landscape ready to be meshed for computer simulations. The city geometry is idealized for non viscous flow simulations and targets ...
  • Challenges in large scale quantum mechanical calculations 

    Ratcliff, Laura E.; Mohr, Stephan; Huhs, Georg; Deutsch, Thierry; Masella, Michel; Genovese, Luigi (Wiley, 2016-11-07)
    Article
    Accés restringit per política de l'editorial
    During the past decades, quantum mechanical methods have undergone an amazing transition from pioneering investigations of experts into a wide range of practical applications, made by a vast community of researchers. First ...
  • Multi-objective scheduling of Scientific Workflows in multisite clouds 

    Liu, Ji; Pacitti, Esther; Valduriez, Patrick; Oliveira, Daniel de; Mattoso, Marta (Elsevier, 2016-10)
    Article
    Accés restringit per política de l'editorial
    Clouds appear as appropriate infrastructures for executing Scientific Workflows (SWfs). A cloud is typically made of several sites (or data centers), each with its own resources and data. Thus, it becomes important to be ...
  • Acceleration strategies for elastic full waveform inversion workflows in 2D and 3D 

    Kormann, Jean; Rodríguez, Juan E.; Ferrer, Miguel; Farrés, Albert; Gutiérrez, Natalia; de la Puente, Josep; Hanzich, Mauricio; Cela, José M. (Springer International Publishing, 2017-02-01)
    Article
    Accés obert
    Full waveform inversion (FWI) is one of the most challenging procedures to obtain quantitative information of the subsurface. For elastic inversions, when both compressional and shear velocities have to be inverted, the ...
  • Multilevel processes and cultural adaptation: examples from past and present small-scale societies 

    Reyes-Garcia, Victoria; Balbo, Andrea L.; Gómez-Baggethun, Erik; Gueze, Maximilien; Mesoudi, Alex; Richerson, Peter J.; Rubio-Campillo, Xavier; Ruiz-Mallén, Isabel; Shennan, Stephen (Resilience Alliance, 2016)
    Article
    Accés obert
    The last two decades have seen a proliferation of research frameworks that emphasise the importance of understanding adaptive processes that happen at different levels. We contribute to this growing body of literature by ...
  • Optimization of atmospheric transport models on HPC platforms 

    de la Cruz, Raúl; Folch, Arnau; Farré, Pau; Cabezas, Javier; Navarro, Nacho; Cela, José M. (Elsevier, 2016-12)
    Article
    Accés restringit per política de l'editorial
    The performance and scalability of atmospheric transport models on high performance computing environments is often far from optimal for multiple reasons including, for example, sequential input and output, synchronous ...
