    Community networks are self-organized and decentralized communication networks built and operated by citizens, for citizens. The consolidation of today's cloud technologies offers now, for community networks, the possibility ...
  • Mobile Autonomous Sensing Unit (MASU): a framework that supports distributed pervasive data sensing 

    Medina Medina, Esunly; López Nuevo, David Andrés; Meseguer Pallarès, Roc; Ochoa, Sergio; Royo Vallés, María Dolores; Santos, Rodrigo (2016-07)
    Article
    Open Access
    Pervasive data sensing is a major issue that transverses various research areas and application domains. It allows identifying people’s behaviour and patterns without overwhelming the monitored persons. Although there are ...
  • Modelado de la trayectoria de los polos en la secuencia de LPC 

    Freitag, Fèlix; Monte Moreno, Enrique; Hernando Pericás, Francisco Javier (Universidad de Valladolid, 1995)
    Conference report
    Open Access
    A alternative way of representing time variations of the speech spectra is presented. We propose to model the trajectories of the poles of the LPC analysis spectra using exponential functions as alternative to delta ...
  • On the use of the derivative of pole trajectories of the LPC analysis parameter sequence as an alternative to delta parameters 

    Freitag, Fèlix; Monte Moreno, Enrique; Hernando Pericás, Francisco Javier (1995)
    Conference report
    Open Access
    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 ...
  • Predictive neural networks applied to phoneme recognition 

    Freitag, Fèlix; Monte Moreno, Enrique; Salavedra Molí, Josep (1997)
    Conference report
    Open Access
    In this paper a phoneme recognition system based on predictive neural networks is proposed. Neural networks are used to predict observation vectors of speech frames. The obtained prediction error is used for phoneme ...
  • Energy efficient cloud service provisioning: Keeping data center granularity in perspective 

    Sharifi, Leila; Cerdà Alabern, Llorenç; Freitag, Fèlix; Veiga, Luis (2016-06)
    Article
    Restricted access - publisher's policy
    The cost of power and its associated delivery are becoming significant factors in the total expenditure of large-scale data centers. Numerous techniques have been proposed to address the energy efficiency issue in cloud ...
  • Applying LTI protocol to exercise solving in a moodle platform 

    Cosp Vilella, Jordi; Meseguer Pallarès, Roc; Martínez García, Herminio (2016-02)
    Article
    Open Access
  • Integration of assisted P2P live streaming service in community network clouds 

    Selimi, Mennan; Apolonia, Nuno; Olid Domínguez, Ferran; Freitag, Fèlix; Navarro Moldes, Leandro; Moll, Agustí; Pueyo, Roger; Veiga, Luis (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Open Access
    Wireless community networks (CNs) are large-scale, self-organized and decentralized communication infrastructures built and operated by citizens for citizens. CN cloud infrastructures have been recently introduced to run ...
  • An experimental methodology to promote and evaluate the use of community networks for civic engagement

  • A MAC protocol for underwater sensors networks 

    Santos, Rodrigo; Orozco, Javier; Ochoa, Sergio; Meseguer Pallarès, Roc; Eggly, Gabriel (2015)
    Conference report
    Restricted access - publisher's policy
    Underwater sensor networks are becoming an important field of research, because of its everyday increasing application scope. Examples of their application areas are environmental and pollution monitoring (mainly oil ...
