    • Sistema de mesura d'acceleròmetres basat en altaveu 

      Ponce Garcia, Bernat (Universitat Politècnica de Catalunya, 2015-05-11)
      Master thesis (pre-Bologna period)
      Open Access
      [ANGLÈS] The Electronic Engineering Department is developing an accelerometer and, in order to check the reliability of its functionality, it is needed to create a system capable of generating vibrations that will make ...
    • Using jitter and shimmer in speaker verification 

      Farrús Cabeceran, Mireia; Hernando Pericás, Francisco Javier (2009-07-01)
      Open Access
      Jitter and shimmer are measures of the fundamental frequency and amplitude cycle-to-cycle variations, respectively. Both features have been largely used for the description of pathological voices, and since they characterise ...
    • Voice coil inter-turn faults modeling and simulation 

      Ruiz Illana, Germán; Ortega Redondo, Juan Antonio; Hernández Guiteras, Joan (2012)
      Conference lecture
      Restricted access - publisher's policy
      The purpose of this paper is to present a new model to study intern-turn short circuit faults in a dynamic loudspeaker. The loudspeaker is modeled by using classical voice coil parametric model attached to a mechanical piston, ...
