    • Characterization of blood pressure signal considering low and high risk stratification in cardiomyopathy patients 

      Arcentales, Andrés; Voss, Andreas; Caminal Magrans, Pere; Bayés-Genís, Antoni; Domingo, Maite; Giraldo Giraldo, Beatriz (2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Ischemic and dilated cardiomyopathy are associated with disorders of myocardium. Using the blood pressure (BP) signal and the values of the ventricular ejection fraction, we obtained parameters for stratifying cardiomyopathy ...

    • Obstructive sleep apnea in a rat model: effects of anesthesia on autonomic evaluation from heart rate variability measures 

      Jané Campos, Raimon; Lázaro, Jesús; Ruiz, Puy; Gil, Eduardo; Navajas, Daniel; Farré, Ramon; Laguna, Pablo (Computing in Cardiology, 2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Rat model of Obstructive Sleep Apnea (OSA) is a realistic approach for studying physiological mechanisms involved in sleep. Rats are usually anesthetized and autonomic nervous system (ANS) could be blocked. This study aimed ...

    • Study of the oscillatory breathing pattern in elderly patients

    • Cardiac interference reduction in diaphragmatic MMG signals during a maintained inspiratory pressure test 

      Sarlabous Uranga, Leonardo; Torres Cebrián, Abel; Fiz Fernández, José Antonio; Jané Campos, Raimon (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      A recursive least square (RLS) adaptive filtering algorithm for reduction of cardiac interference in diaphragmatic mecanomyographic (MMGdi) signals is addressed in this paper. MMGdi signals were acquired with a capacitive ...

    • Characterization of laplacian surface electromyographic signals during isometric contraction in biceps brachii 

      Estrada, Luis; Torres Cebrián, Abel; Garcia Casado, Javier; Prats Boluda, Gema; Jané Campos, Raimon (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Surface electromyography (sEMG) is a noninvasive technique for monitoring the electrical activity produced by the muscles. Usually, sEMG is performed by carrying out monopolar or bipolar recordings by means of conventional ...

    • Fault tolerant control design for polytopic uncertain LPV systems: application to a quadrotor 

      Rotondo, Damiano; Nejjari Akhi-Elarab, Fatiha; Torres Cebrián, Abel; Puig Cayuela, Vicenç (2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper presents a Fault Tolerant Control (FTC) design for polytopic uncertain Linear Parameter-Varying (LPV) systems, applied to an aerospace application: a quadrotor. Depending on the information available about the ...

    • Estimation of instantaneous frequency from empirical mode decomposition on respiratory sounds analysis 

      Lozano, Manuel; Fiz Fernández, José Antonio; Jané Campos, Raimon (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Instantaneous frequency (IF) calculated by empirical mode decomposition (EMD) provides a novel approach to analyze respiratory sounds (RS). Traditionally, RS have been analyzed using classical time-frequency distributions, ...

    • Respiratory and spontaneous arousals in patients with sleep apnea hypopnea syndrome 

      Gil de Mesquita, Joana Margarida; Poree, F.; Carrault, Guy; Fiz Fernández, José Antonio; Abad, Jorge; Jané Campos, Raimon (Institute of Electrical and Electronics Engineers (IEEE), 2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Sleep in patients with Sleep Apnea-Hypopnea Syndrome (SAHS) is frequently interrupted with arousals. Increased amounts of arousals result in shortening total sleep time and repeated sleep-arousal change can result in sleep ...

    • Improving the development of surgical skills with virtual fixtures in simulation 

      Hernansanz Prats, Alberto; Zerbato, Davide; Gasperotti, Lorenza; Scandola, Michele; Fiorini, Paolo; Casals Gelpí, Alicia (Springer, 2012)
