      Article
      Accés obert
      A new simple closed-form equation that accurately predicts the effect of an arbitrarily large constant axial load, residual stress or temperature shift on the natural frequencies of an uniform single-span beam, with various ...
    • On the ability of adaptation of speech signals and data hiding 

      Ballesteros, D.M.L.; Moreno Aróstegui, Juan Manuel (2012-11-15)
      Article
      Accés restringit per política de l'editorial
      The efficient wavelet masking is a scheme of speech-in-speech hiding based on the ability of adaptation of speech signals under the hypothesis “any (speech) secret signal may seem similar to a (speech) host signal if its ...
    • SNAVA—A real-time multi-FPGA multi-model spiking neural network simulation architecture
