Automatic detection of P- and S- wave arrival times: new strategies based on the modified fractal method and basic matching pursuit
(Springer, 2017)
In this work, new strategies for automatic identification of P- and S-wave arrival times from digital recorded local seismograms are proposed and analyzed. The database of arrival times previously identified by a human ...
Muestreo compresivo utilizando Orthogonal Matching Pursuit (OMP)
(2011-10-13)
Muestreo Compresivo es una rama emergente del procesamiento de señales, basada en el hecho de que un número pequeño de proyecciones lineales no adaptativas sobre una señal compresible, contienen suficiente información para ...

Loss of sleep spindle frequency deceleration in Obstructive Sleep Apnea
(2013-07-29)
Objective: Sleep spindles have been suggested as surrogates of thalamo-cortical activity. Internal frequency modulation within a spindle's time frame has been demonstrated in healthy subjects, showing that spindles tend ...

EEG alpha rhythm detection on a portable device
(Elsevier B.V., 2019-07-01)
Portable EEG devices have a great potential to become efficient computer interfaces. However, a necessary step is to accurately describe the EEG signal in order to quantify brain rhythms. This study explored two signal ...
Analysis of EEG sleep spindle parameters from apnea patients using massive computing and decision tree
(2014)
In this study, Matching Pursuit (MP) procedure is applied to the detection and analysis of EEG sleep spindles in patients evaluated for suspected OSAS. Elements having the frequency of EEG sleep spindles are selected from ...
