    The electromyography (EMG) signal is the summation of traveling motor unit (MU) action potentials that propagate along the fibers from the neuromuscular junction (Innervation Zone, IZ) to the tendons with a certain conduction ...
  • Optimization techniques in respiratory control system models 

    Serna Higuita, Leidy Yanet; Mañanas Villanueva, Miguel Ángel; Marín Sánchez, Jesús; Hernández Valdivieso, Alher Mauricio; Benito, S. (2016-11-01)
    Article
    Accés restringit per política de l'editorial
    One of the most complex physiological systems whose modeling is still an open study is the respiratory control system where different models have been proposed based on the criterion of minimizing the work of breathing ...
  • Novel Modeling of Work of Breathing for Its Optimization During Increased Respiratory Efforts 

    Serna Higuita, Leidy Yanet; Mañanas Villanueva, Miguel Ángel; Hernández Valdivieso, Alher Mauricio; Marín Sánchez, Jesús; Benito Vales, Salvador (2016-09-01)
    Article
    Accés obert
    The respiratory control system is one of the most complex physiological systems, whose controller has been extensively modeled based on the criterion of minimizing work of breathing (WOB). However, cost functions and their ...
