Auto-correlation in the motor/imaginary human EEG signals: A vision about the FDFA fluctuations.
Autor: Gilney Figueira Zebende, Florêncio Mendes Oliveira Filho, Juan Alberto Leyva Cruz
Publikováno v: PLoS ONE, Vol 12, Iss 9, p e0183121 (2017)
In this paper we analyzed, by the FDFA root mean square fluctuation (rms) function, the motor/imaginary human activity produced by a 64-channel electroencephalography (EEG). We utilized the Physionet on-line databank, a publicly available database of

Innovative instrumentation to strong reduction of the noise levels inside newborn incubators used in the neonatal intensive care units
Autor: Paulo Roberto Medina Ramos, Gilney Figueira Zebende, Juan Alberto Leyva Cruz
Publikováno v: Biomedical Physics & Engineering Express. 9:045012
In spite of the advent of medical technology, modern newborn incubators (NIs) do not protect them from high noise levels in the neonatal intensive care units (NICUs). Allied to bibliographical research carried out measurements were made inside the do
