    • Analysis of source separation algorithms in industrial acoustic environments 

      Lozano, Clevis; Gómez, Andrés; Chacón-Rodríguez, Alfonso; Merchán, Fernando; Julián, Pedro (Institute of Electrical and Electronics Engineers Inc., 2015)
      This paper shows the results from the computation cost evaluation of three blind source separation algorithms. The algorithms tested were: FastICA, Adaptive Algorithm Based on Natural Gradient, and Adaptive EASI Based on ...

    • Design of an IDM-based determinant computing unit for a 130nm low power CMOS ASIC acoustic localization processor 

      Cerdas-Robles, Roberto; Rodríguez, Agustín; Julián, Pedro; Chacón-Rodríguez, Alfonso (Institute of Electrical and Electronics Engineers Inc., 2015-09)
      A determinant computing circuit in floating point format has been designed and tested for use in a CMOS ASIC acoustic localization processor. The Internal Division Method (IDM) was used to implement the operation, employing ...

    • Digital integrated circuit implementation of an identification stage for the detection of illegal hunting and logging 

      Salazar-García, Carlos; Alfaro-Hidalgo, Luis; Carvajal-Delgado, Mauricio; Montero-Aragón, Jordan; Castro-Gonzalez, Reinaldo; Agustín-Rodríguez, Juan; Chacón-Rodríguez, Alfonso; Alvarado-Moya, Pablo (Institute of Electrical and Electronics Engineers Inc., 2015-09)
      Results of the VLSI implementation of an acoustic classification system's identification stage, intended for the detection of gunshots and chainsaws in a protected tropical area, are shown, with the idea of later building ...
