  • Adaptive vector predictive speech coding with sample by sample update at 16 Kbps 

    Masgrau Gómez, Enrique José; Mariño Acebal, José Bernardo (1986)
    Text en actes de congrés
    Accés obert
    A vectorial generalization of the ADPCM system is introduced. Once the speech signal is grouped in vectors, they are coded using a vector predictor (VP) and a vector quantizer (VQ). Both subsystems are continously adaptive; ...

  • Adaptivity based on error estimation for viscoplastic softening materials 

    Díez, Pedro; Arroyo Balaguer, Marino; Huerta, Antonio (2000-02)
    Article
    Accés obert
    This paper focuses on the numerical simulation of strain softening mechanical problems. Two problems arise: (1) the constitutive model has to be regular and (2) the numerical technique must be able to capture the two scales ...
