    A fundamentally new idea in grid generated turbulence is the 3D Sparse Grid (3DS) concept [N. A. Malik. Sparse 3D Multi-Scale Grid Turbulence Generator. US Patent No. US 9,599,269 B2 (2017)] which reduces the effective ...
  • Exploring paradigm shift impacts in urban mobility: autonomous vehicles and smart cities 

    Medina Tapia, Marcos Christian; Robusté Antón, Francesc (2018)
    Text en actes de congrés
    Accés obert
    Urban mobility is a dynamic system that has had a (slow) natural evolution. Scientists and engineers are currently developing new mobility technologies. A progressive paradigm shift will change everything from the fuel ...
  • Cell-DEVS modeling and simulation of artificial hydraulic fracturing of rocks in boreholes (WIP) 

    Oyelowo, I.; Wainer, G.; Echegini, N.S.; Ukeme, J.B.; Zlotnik, Sergio (Society for Computer Simulation International, 2018)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Hydraulic Fracturing is a technique used in the extraction and exploration of oil and gas. During hydraulic fracturing, a high-pressure fluid is injected into a wellbore; this fluid flows through some artificially made ...
  • Natural drainage basins as fundamental units for mine closure planning: Aurora and Pastor I quarries 

    Martín-Moreno, Cristina; Tejedor, María; Martín, José; Nicolau, José; Bladé i Castellet, Ernest; Nyssen, Sara; de Lys, Alejandro; Cermeño-Martín, Ivon; Gómez, José (2018)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    The vast majority of the Earth’s ice-free land surface has been shaped by fluvial and related slope geomorphic processes. Drainage basins are consequently the most common land surface organization units. Mining operations ...
