    • Effects of stray capacitance to ground in impedance measurements 

      Aliau Bonet, Carles; Quílez Figuerola, Marcos (Elsevier, 2021)
      Capítol de llibre
      Accés restringit per política de l'editorial
      Inductive effects such as positive phase angles in impedance measurements have often confused the researchers when the material measured is nonmagnetic. When the measurement is based on auto-balancing bridge method and the ...

      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this contribution we aim at proposing entropy measurements in resistive elements to characterize the induced damage due to current and Joule effect dissipation. 0.25 W off the shelf resistors are biased with constant ...

    • Initial analysis of SAR from a cell phone inside a vehicle by numerical computation.

      Este trabajo presenta una nueva plataforma de interacción de usuarios con discapacidad con los juegos de las principales videoconsolas comerciales. El sistema diseñado habilita el acceso a las diferentes plataformas ...

    • Interfaz gestual para el acceso a plataformas digitales y control de plataformas para el ocio 

      Hornero Ocaña, Gemma; Quílez Figuerola, Marcos; Casas Piedrafita, Óscar (2015)
      Comunicació de congrés
      Accés obert
      La tetraplejia y la paraplejia son discapacidades que resultan de las lesiones en la médula espinal y trastornos neuromusculares tales como la parálisis cerebral. Los pacientes que las padecen presentan diferentes niveles ...

    • Irreversible entropy model for damage diagnosis in resistors 

      Cuadras Tomàs, Àngel; Crisóstomo, Javier; Ovejas Benedicto, Victòria Júlia; Quílez Figuerola, Marcos (American Institute of Physics (AIP), 2015-10-28)
      Article
      Accés obert
      We propose a method to characterize electrical resistor damage based on entropy measurements. Irreversible entropy and the rate at which it is generated are more convenient parameters than resistance for describing damage ...
