      Text en actes de congrés
      Accés obert
      Diaphragm electromyography (EMGdi) provides important information on diaphragm activity, to detect neuromuscular disorders of the most important muscle in the breathing inspiratory phase. EMGdi is habitually recorded using ...

    • Cancellation of cardiac interference in diaphragm EMG signals using an estimate of ECG reference signal 

      Torres Cebrián, Abel; Fiz Fernández, José Antonio; Jané Campos, Raimon (2014)
      Text en actes de congrés
      Accés obert
      The analysis of the electromyographic signal of the diaphragm muscle (EMGdi) can provide important information in order to evaluate the respiratory muscular function. However, EMGdi signals are usually contaminated by the ...

    • Evaluation of Laplacian diaphragm electromyographic recording in a dynamic inspiratory maneuver 

      Estrada, Luis; Torres Cebrián, Abel; Garcia Casado, Javier; Prats Boluda, Gema; Ye-Lin, Y.; Jané Campos, Raimon (2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The analysis of the electromyographic signal of the diaphragm muscle (EMGdi) can provide important information for evaluating the respiratory muscular function. The EMGdi can be recorded using surface Ag/AgCl disc electrodes ...

    • Identification of Obstructive Sleep Apnea patients from tracheal breath sound analysis during wakefulness in polysomnographic studies 

      Solà Soler, Jordi; Fiz Fernández, José Antonio; Torres Cebrián, Abel; Jané Campos, Raimon (2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Obstructive Sleep Apnea (OSA) is currently diagnosed by a full nocturnal polysomnography (PSG), a very expensive and time-consuming method. In previous studies we were able to distinguish patients with OSA through formant ...

    • A recurrent neural network approach for 3d vision-based force estimation 

      Avilés Rivero, Angélica Ivone; Marbán González, Arturo; Sobrevilla Frisón, Pilar; Casals Gelpí, Alicia; Fernández Ruzafa, José (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Robotic-assisted minimally invasive surgery has demonstrated its benefits in comparison with traditional procedures. However, one of the major drawbacks of current robotic system approaches is the lack of force feedback. ...

    • Unconstrained L1-regularized minimization with interpolated transformations for heart motion compensation 

      Avilés Rivero, Angélica Ivone; Sobrevilla Frisón, Pilar; Casals Gelpí, Alicia (2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Motion compensation constitutes a challenging issue in minimally invasive beating heart surgery. Since the zone to be repaired has a dynamic behaviour, precision and surgeon's dexterity decrease. In order to solve this ...
