• A machine learning model for emotion recognition from physiological signals 

      Domínguez-Jiménez, J.A.; Campo Landines, Kiara; Martínez-Santos, J.C.; De la Hoz Domínguez, Enrique José; Contreras Ortiz, Sonia Helena (Elsevier Ltd, 2020)
      Emotions are affective states related to physiological responses. This study proposes a model for recognition of three emotions: amusement, sadness, and neutral from physiological signals with the purpose of developing a ...
    • A novel approach for QRS complex detection in patients with atrial arrhythmia 

      Giraldo-Guzmán J.; Ruiz, Elkin; Magre Colorado, Luz Alejandra; Bautista Lasprilla, Gloria Isabel; Kotas, Marian (Cartagena de Indias, 2020-11-03)
      Atrial fibrillation (AF) is the most common cardiac arrhythmia in the world which shows rising prevalence leading to increased comorbidities, such as, Ischemic heart disease and Stroke that the main cause of deaths in the ...
    • Analysis and Classification of Evoked Potentials in Response to Familiar and Unfamiliar Faces 

      Sanchez-Hernandez S.A.; Contreras Ortiz, Sonia Helena (Institute of Electrical and Electronics Engineers Inc., 2018)
      Brain activity during perception and recognition of faces have been studied by researchers with the purpose to develop brain-computer interfaces and to study neurological disorders. In this paper, we analyzed evoked ...
    • Application of spatio-temporal filtering for atrial activity waveforms enhancement 

      Giraldo-Guzmán J.; Kotas, Marian; Piela M.; Castells F.; Łęski J.M.; Contreras Ortiz, Sonia Helena (Association for Computing Machinery, 2019)
      In this paper, we propose to apply spatio-temporal filtering to atrial activity enhancement, prior to the detection of possible atrial arrhythmias. During normal sinus rhythm, the atrial activity is well synchronized with ...
    • Design of an electronic system for monitoring muscle activity in weight-lifting 

      Mercado-Medina E.L.; Chavarro-Hernandez Z.D.; Domínguez Jiménez, Juan Antonio; Contreras Ortiz, Sonia Helena (Institute of Electrical and Electronics Engineers Inc., 2014)
      Electronic systems based on body area networks can be used to monitor sports performance. These systems use sensors to acquire signals from the athlete while performing the exercises, and a communication system to transmit ...
    • Fetal ECG extraction using independent component analysis by Jade approach 

      Giraldo-Guzmán J.; Contreras Ortiz, Sonia Helena; Lasprilla G.I.B.; Kotas, Marian (SPIE, 2017)
      Fetal ECG monitoring is a useful method to assess the fetus health and detect abnormal conditions. In this paper we propose an approach to extract fetal ECG from abdomen and chest signals using independent component analysis ...
