    • Infinitely oscillating wavelets and a efficient implementation algorithm based the FFT 

      Fabio, Marcela; Serrano, Eduardo P. (2015-01-01)
      In this work we present the design of an orthogonal wavelet, infinitely oscillating, located in time with decay 1/|t|n and limited-band. Its appli- cation leads to the signal decomposition in waves of instantaneous, well ...

    • Joint Kalman–Haar Algorithm Applied to Signal Processing 

      Viegener, Alejandro; Sirne, Ricardo O.; Sirne, Ricardo O.; Serrano, Eduardo P.; Serrano, Eduardo P.; Fabio, Marcela; Fabio, Marcela; D'Attellis, Carlos E.; D'Attellis, Carlos E. (2012-03-08)
      Under the analysis of signals disturbed by noise, in this paper we propose a working methodology aimed to seize the best estimate of combining Kalman filtering with the characterization that is achieved by applying a ...

    • Regularidad local del Mercado de índices para la crisis económica de 2008 

      Figliola, Alejandra; Rosenblatt, Mariel; Serrano, Eduardo P. (2012-03-08)
      There is evidence that signals from financial markets, such as stock indices, interest rates or commodities, have a multifractal nature. In recent years, many efforts have been made to relate the inefficiency of markets ...

    • 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 ...
