• Checking complex networks indicators in search of singular episodes of the photochemical smog 

      Carmona-Cabezas, Rafael; Gómez-Gómez, Javier; Gutiérrez de Ravé Agüera, Eduardo; Jiménez-Hornero, Francisco José (Elsevier, 2020)
      A set of indicators derived from the analysis of complex networks have been introduced to identify singularities on a time series. To that end, the Visibility Graphs (VG) from three different signals related to photochemical ...
    • Improving graph-based detection of singular events for photochemical smog agents 

      Carmona-Cabezas, Rafael; Gómez-Gómez, Javier; Gutiérrez de Ravé Agüera, Eduardo; Sánchez-López, Elena; Serrano, João; Jiménez-Hornero, Francisco José (Elsevier, 2020)
      Recently, a set of graph-based tools have been introduced for the identification of singular events of O3, NO2 and temperature time series, as well as description of their dynamics. These are based on the use of the ...
    • Multiplex Visibility Graphs as a complementary tool for describing the relation between ground level O3 and No2 

      Carmona-Cabezas, Rafael; Gómez-Gómez, Javier; Ariza Villaverde, Ana Belén; Gutiérrez de Ravé Agüera, Eduardo; Jiménez-Hornero, Francisco José (Elsevier, 2020)
      The usage of multilayer complex networks for the analysis of correlations among environmental variables (such as O3and NO2concentrations from the photochemical smog) is investigated in this work. The mentioned technique ...
