  • Random forest parameterization for earthquake catalog generation 

    Llácer Giner, David; Otero Calviño, Beatriz; Tous Liesa, Rubén; Monterrubio Velasco, Marisol; Carrasco Jiménez, José; Rojas Ulacio, Otilio (Springer, 2020)
    Conference report
    Open Access
    An earthquake is the vibration pattern of the Earth’s crust induced by the sliding of geological faults. They are usually recorded for later studies. However, strong earthquakes are rare, small-magnitude events may pass ...
  • Toward an interdisciplinary methodology to solve new (old) transportation problems 

    Graells-Garrido, Eduardo; Peñas-Araya, Vanessa (Association for Computing Machinery (ACM), 2020)
    Conference lecture
    Open Access
    The rising availability of digital traces provides a fertile ground for new solutions to both, new and old problems in cities. Even though a massive data set analyzed with Data Science methods may provide a powerful solution ...
  • Parallel SFC-based mesh partitioning and load balancing 

    Borrell Pol, Ricard; Oyarzun Altamirano, Guillermo; Dosimont, Damien; Houzeaux, Guillaume (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Open Access
    Modern supercomputers allow the simulation of complex phenomena with increased accuracy. Eventually, this requires finer geometric discretizations with larger numbers of mesh elements. In this context, and extrapolating ...
  • Urgent supercomputing of earthquakes: use case for civil protection 

    Puente, Josep de la; Rodríguez Rodríguez, Juan Esteban; Monterrubio Velasco, Marisol; Rojas, Otilio (Association for Computing Machinery (ACM), 2020)
    Conference report
    Open Access
    Deadly earthquakes are events that are unpredictable, relatively rare and have a huge impact upon the lives of those who suffer their consequences. Furthermore, each earthquake has specific characteristics (location, ...
  • Wakes and instabilities of static and freely vibrating cylinders 

    Rodríguez Pérez, Ivette María; Lehmkuhl, Oriol; Pastrana Maldonado, Daniel; Cajas García, Juan Carlos; Houzeaux, Guillaume (Springer, 2019)
    Conference report
    Restricted access - publisher's policy
    The flow around static and freely vibrating cylinders are of interest in understanding different phenomena encountered in many practical applications.
  • A constellation of horrors: analysis and visualization of the #Cuéntalo movement 

    Bucalo Mana, María Soledad; Calvo, Luz; Cucchietti, Fernando; García Povedano, David; García Sáez, Artur; Gómez Celis, Juan Felipe; Arcadio González, Camilo; Marín, Guillermo; Reyes, Patricio; Serra Burriel, Feliu; Vélez García, Diana Fernanda; Meta, Irene (Association for Computing Machinery (ACM), 2019)
    Conference report
    Open Access
    In this work, we analyze content and structure of the Twitter trending topic #cuentalo with the purpose of providing a visualization of the movement. A supervised learning methodology is used to train the classifying ...
  • Local bisection for conformal refinement of unstructured 4D simplicial meshes 

    Belda Ferrín, Guillem; Gargallo Peiró, Abel; Roca Navarro, Francisco Javier (Springer, 2018)
    Conference report
    Open Access
    We present a conformal bisection procedure for local refinement of 4D unstructured simplicial meshes with bounded minimum shape quality. Specifically, we propose a recursive refine to conformity procedure in two stages, ...
  • Defining a stretching and alignment aware quality measure for linear and curved 2D meshes 

    Aparicio Estrems, Guillermo; Gargallo Peiró, Abel; Roca Navarro, Francisco Javier (Springer, 2018)
    Conference report
    Open Access
    We define a regularized shape distortion (quality) measure for curved high-order 2D elements on a Riemannian plane. To this end, we measure the deviation of a given 2D element, straight-sided or curved, from the stretching ...
  • A semantic model to fight social exclusion 

    Ortiz Santiago, Víctor Alejandro; Estañol Lamarca, Montserrat; Marinescu, Maria Cristina; Sancho Samsó, María Ribera; Teniente López, Ernest; Rueda Palenzuela, Carmen (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Open Access
    This work presents a semantic model meant to help with the identification and prediction of individuals at risk of social exclusion. The model is based on the self-sufficiency matrix, a tool that evaluates a person's ...
  • Long short-term memory networks for earthquake detection in Venezuelan regions 

    Mus León, Sergi; Gutiérrez Escobar, Norma; Tous Liesa, Rubén; Otero Calviño, Beatriz; Cruz de la Cruz, Stalin Leonel; Llácer Giner, David; Alvarado Bermúdez, Leonardo; Rojas, Otilio (Springer, 2019)
    Conference lecture
    Open Access
    Reliable earthquake detection and location algorithms are necessary to properly catalog and analyze the continuously growing seismic records. This paper reports the results of applying Long Short-Term Memory (LSTM) networks ...
  • Noise Radiated by an Open Cavity at Low Mach Number 

    Martín Navarrete, Rocío; Soria Guerrero, Manel; Lehmkuhl, Oriol; Gorobets, Andrei; Cante Terán, Juan Carlos; Vidal Pairot, Pere (2018)
    Conference report
    Restricted access - publisher's policy
    The present work focuses on the study of noise generation and radiation of unsteady laminar flow over an open three dimensional cavity at low Mach number, that is of interest to understand noise generation mechanisms in ...
  • Large eddy simulation for automotive aerodynamics with Alya 

    Lehmkuhl, Oriol; Chrysokentis, Georgios; Gomez, Samuel; Owen, Herbert (2018-07-09)
    Conference lecture
    Open Access
    The prodigious potential offered by the ever-growing computing infrastructure is fostering the use of large eddy simulation for automotive aerodynamics. This approach, which resolves the larger dynamically important eddies ...
