  • Design and implementation of high-performance memory systems for future packet buffers 

    García Vidal, Jorge; Corbal San Adrián, Jesús; Cerdà Alabern, Llorenç; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2003)
    Text en actes de congrés
    Accés obert
    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 ...
  • Game theory framework for MAC parameter optimization in energy-delay constrained sensor networks 

    Doudou, Messaoud; Barceló Ordinas, José María; Djenouri, Djamel; García Vidal, Jorge; Bouabdallah, Abdelmadjid; Badache, Nadjib (2016-05)
    Article
    Accés obert
    Optimizing energy consumption and end-to-end (e2e) packet delay in energy-constrained, delay-sensitive wireless sensor networks is a conflicting multiobjective optimization problem. We investigate the problem from a game ...
  • 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 ...
  • Reputation-based joint scheduling of households appliances and storage in a microgrid with a shared battery 

    Alskaif, Tarek; Luna, Adriana C.; Guerrero Zapata, Manel; Guerrero, Josep M.; Bellalta Jimenez, Boris (2017-03-01)
    Article
    Accés restringit per política de l'editorial
    Due to the decreasing revenues from the surplus renewable energy injected into the grid, mechanisms promoting self-consumption of this energy are becoming increasingly important. Demand response (DR) and local storage are ...
  • 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 ...
  • Energy efficiency of MAC protocols in low data rate wireless multimedia sensor networks: A comparative study 

    Alskaif, Tarek; Bellalta Jimenez, Boris; Guerrero Zapata, Manel; Barceló Ordinas, José María (Elsevier, 2017-03-01)
    Article
    Accés restringit per política de l'editorial
    Some new application scenarios for Wireless Sensor Networks (WSNs) such as urban resilience, smart house/building, smart agriculture and animal farming, among others, can be enhanced by adding multimedia sensors able to ...
  • 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 

    Medina Medina, Esunly; Vega d'Aurelio, Davide; Meseguer Pallarès, Roc; Medina, Humberto; Ochoa, Sergio; Magnani, Matteo (2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Collaborative learning activities have shown to be useful to address educational processes in several contexts. Monitoring these activities is mandatory to determine the quality of the collaboration and learning processes. ...
  • Providing behaviour awareness in collaborative project courses 

    Medina Medina, Esunly; Meseguer Pallarès, Roc; Ochoa, Sergio; Medina, Humberto (2016-10-01)
    Article
    Accés obert
    Several studies show that awareness mechanisms can contribute to enhance the collaboration process among students and the learning experiences during collaborative project courses. However, it is not clear what awareness ...
  • A distributed power sharing framework among households in microgrids: a repeated game approach 

    Alskaif, Tarek; Guerrero Zapata, Manel; Bellalta Jimenez, Boris; Nilsson, Anders (2017-01-01)
    Article
    Accés restringit per política de l'editorial
    In microgrids, the integration of distributed energy resources (DERs) in the residential sector can improve power reliability, and potentially reduce power demands and carbon emissions. Improving the utilization of renewable ...
