    • Aircraft localization using a passive acoustic method. Experimental test 

      Martín Román, Sara-Regina; Genesca Francitorra, Meritxell; Romeu Garbí, Jordi; Clot Razquin, Arnau (2016-01)
      Article
      Open Access
      A passive acoustic method for aircraft localization is experimentally tested in this paper. The method relies on the Doppler effect influencing the signals received by a mesh of microphones distributed over the acoustic ...
    • Analysis and characterization of coupled transmission lines loaded with complementary spiral resonators 

      Gil Galí, Ignacio; Fernández García, Raúl; Balcells Sendra, Josep (2011-02-21)
      Article
      Restricted access - publisher's policy
      In this study, the behaviour of coupled microstrip transmission lines loaded with complementary spiral resonators (CSRs) is analysed in depth. CSRs are constitutive elements for the synthesis of metamaterials with negative ...
    • Mobile distributed wireless stereo 

      Berbel Gonzalez, Elisabet (Universitat Politècnica de Catalunya, 2010-01-18)
      Master thesis
      Open Access
    • Realitat augmentada amb "head transfer response function" (HTRF) 

      Díaz Cívico, Eric (Universitat Politècnica de Catalunya, 2019-05-22)
      Bachelor thesis
      Restricted access - author's decision
      La "head transfer response function" (HTRF) és un funció que permet processar un so de manera que a un oient amb el dispositiu adient (habitualment uns auriculars) li sembli que el so provingui d'un punt en concret. En ...
    • Simulació, control i mesura del patró de directivitat d'un sistema array de fonts sonores 

      Castan Girona, Albert (Universitat Politècnica de Catalunya, 2016-06-09)
      Bachelor thesis
      Restricted access - author's decision
      Per incrementar la intel·ligibilitat d’un sistema de so, és convenient poder controlar la directivitat de les fonts sonores. Aquest control dóna com a resultat la projecció del so a àrees específiques, intentant al mateix ...
    • Sound directivity by PT-symmetric acoustic dipoles 

      Magariyachi, Tetsu; Arias Casals, Helena; Herrero Simon, Ramon; Botey Cumella, Muriel; Staliunas, Kestutis (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2021)
      Conference report
      Open Access
      The new physics of open-dissipative, non-Hermitian systems have become a fruitful playground to uncover novel physical phenomena, even in exotic or counterintuitive ways, especially in optics and, more recently, also in ...
    • Study: numerical tools for computational aeroacoustics 

      Eiximeno Franch, Benet (Universitat Politècnica de Catalunya, 2020-06-30)
      Bachelor thesis
      Restricted access - author's decision
      Aeroacoustics is the study of the noise produced by an airflow. The present work is focused on implementing a suite of code including a parallel code in C and scripts in Matlab and Python that can, coupled with a CFD ...
    • Terminal digital para la transmisión de voz y datos sobre banda fónica 

      Rodríguez Fonollosa, José Adrián; Ymbern García, Marcelo; Masgrau Gómez, Enrique José (Consejo Superior de Investigaciones Científicas (CSIC), 1986)
      Conference report
      Open Access
      The development of a terminal for voice and data transmision based on the TMS 32010 one-chip microprocessor is described. Simple solutions are provided for the digital implementations of the filters, compandor, equalizer ...
