  • A fast method to estimate body capacitance to ground at mid frequencies 

    Aliau Bonet, Carles; Pallàs Areny, Ramon (University of Oslo, 2015-12-18)
    Article
    Accés obert
    Impedance measurements that involve the human body are affected by the capacitance between the body and earth ground. This paper describes a fast method to estimate that apacitance at 10 kHz, which is valid for impedance ...
  • A fast OFDM-CDMA user demultiplexing architecture 

    Marti Puig, Pere; Sala Álvarez, José (Institute of Electrical and Electronics Engineers (IEEE), 2000)
    Text en actes de congrés
    Accés obert
    A fast algorithm based on a butterfly structure is presented that demultiplexes the symbols of a particular type of MC-MA (multi-carrier multiple-access) modulation previously proposed for indoor radio communications. A ...
  • A fast one-pass-training feature selection technique for GMM-based acoustic event detection with audio-visual data 

    Butko, Taras; Nadeu Camprubí, Climent (2010)
    Text en actes de congrés
    Accés obert
    Acoustic event detection becomes a difficult task, even for a small number of events, in scenarios where events are produced rather spontaneously and often overlap in time. In this work, we aim to improve the detection ...
