    Contexto: Las mezclas asfálticas drenantes son definidas como aquellas cuyos vacíos con aire oscilan entre 20% y 25%, y emplean como ligante, un asfalto modificado con algún polímero principalmente elastomérico. A diferencia ...
  • Testing stabilization of high-plasticity clays used in sloping terrain by adding sodium silicate 

    FLOREZ-GONGORA, CARLOS; Garzón-Peña, A T; Molina-Giraldo, R D (Journal of Physics: Conference SeriesReino Unido, 2020-08-05)
    High-plasticity clays can be stabilized by the addition of a small percentage of sodium silicate. Sixteen mixtures of 4000 g with different concentrations of sodium silicate at difference percentage were designed, to which ...
  • Proposal for a system model for offline seismic event detection in Colombia 

    Miranda, Julian; Flórez Abril, Angélica; Ospina, Gustavo; Gamboa, Ciro Alberto; Altuve, Miguel; FLOREZ-GONGORA, CARLOS (Future InternetSuiza, 2020-12-18)
    This paper presents an integrated model for seismic events detection in Colombia using machine learning techniques. Machine learning is used to identify P-wave windows in historic records and hence detect seismic events. ...
