    • Time-frequency methods based on the wavelet transform 

      Serrano, Eduardo P.; Fabio, Marcela; Figliola, Alejandra (2012-07-01)
      The information contained in an analog signal is reveled by its numerical representation. The Fourier pair, in two complementary representations, expounds time and frequency structures. However, to detect and characterize ...
    • Variants of the mixed postman problem solvable using linear programming 

      Zaragoza Martínez, Francisco Javier; López Bracho, Rafael (2012-07-01)
      Given a connected mixed graph with costs on its edges and arcs, the mixed postman problem consists of finding a minimum cost closed tour of the mixed graph traversing all of its edges and arcs. It is well-known that this ...
