    In this paper, we address the design of a future high-speed router that supports line rates as high as OC-3072 (160 Gb/s), around one hundred ports and several service classes. Building such a high-speed router would raise ...
  • Phoneme recognition with statisticasl modeling of the prediction of the error of neural networks 

    Freitag, Fèlix; Monte Moreno, Enrique (Robert H. Mannel and Jordi Robert-Ribes, 1998)
    Text en actes de congrés
    Accés obert
    This paper presents a speech recognition system which incorporates predictive neural networks. The neural networks are used to predict observation vectors of speech. The prediction error vectors are modeled on the state ...
  • On the use of the derivative of the pole trajectories of the LPC analysis parameter sequence as an alternative to delta parameters 

    Freitag, Fèlix; Monte Moreno, Enrique; Hernando Pericás, Francisco Javier (ESCA - J.M. PARDO, E. ENRIQUEZ, J. ORTEGA, J. FERREIROS GTM-UPM, 1995)
    Text en actes de congrés
    Accés obert
    In this paper a new approach for modelling time variations in the speech spectra is presented. We propose to approximate the trajectories of the frequency and amplitude of the poles of the LPC spectra with exponential ...
  • Scheduling real-time traffic in underwater acoustic wireless sensor networks 

    Santos, Rodrigo; Orozco, Javier; Micheletto, Matías; Ochoa, Sergio; Meseguer Pallarès, Roc; Millán, Pere; Molina Clemente, Carlos Maria (2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Underwater sensor networks are an important field of research. Several applications require the use of this kind of networks like tsunami or oil spill alerts. The underwater medium is very harsh and only acoustic signals ...
  • Using indirect blockmodeling for monitoring students roles in collaborative learning networks
