Advanced implementation and realization of TFDs
( Elsevier Inc. , 2016 , Book chapter)The design of efficient algorithms is the key to effective utilization of the properties of time-frequency distributions (TFDs) for real-life applications. This chapter presents the needed procedures, techniques, and ... -
Instantaneous frequency based newborn EEG seizure characterisation
(2012 , Article)The electroencephalogram (EEG), used to noninvasively monitor brain activity, remains the most reliable tool in the diagnosis of neonatal seizures. Due to their nonstationary and multi-component nature, newborn EEG seizures ... -
Orthogonalized partial directed coherence for functional connectivity analysis of newborn EEG
(2012 , Conference Paper)The aim of this study is to develop a time-frequency method and test its applicability to investigating directional cortical connectivity in the newborn brain considering the effect of volume conduction. We modified ... -
Time-frequency analysis of heart rate variability in neonatal piglets exposed to hypoxia
(2011 , Conference Paper)To determine whether the sympathetic nervous system plays any role in the inter-individual variation of cardiovascular response to hypoxia in newborns, neonatal heart rate variability (HRV) analysis was used to assess ... -
Time-frequency detection of slowly varying periodic signals with harmonics: Methods and performance evaluation
(2011 , Article)We consider the problem of detecting an unknown signal from an unknown noise type. We restrict the signal type to a class of slowly varying periodic signals with harmonic components, a class which includes real signals ... -
Time-frequency methodologies in neurosciences
( Elsevier Inc. , 2016 , Book chapter)This chapter presents a number of time-frequency (t,f) techniques that can provide advanced solutions to several problems in neuro-sciences with focus on the monitoring of brain abnormalities using EEG and other physiological ...
