A Nonlinear Model of Newborn EEG with Nonstationary Inputs
(
Springer US
, 2010 , Article)
Newborn EEG is a complex multiple channel
signal that displays nonstationary and nonlinear characteristics.
Recent studies have focussed on characterizing the
manifestation of seizure on the EEG for the purpose of
automated ...
Improved Discrete Definition of Quadratic Time-Frequency Distributions
(
IEEE
, 2010 , Article)
Computation of a time-frequency distribution (TFD) requires a discrete version of the continuous distribution. This discrete TFD (DTFD) should be free from aliasing and conserve all the important mathematical properties ...
Multiple-view time-frequency distribution based on the empirical mode decomposition
(
Institution of Engineering and Technology
, 2010 , Article)
This study proposes a novel, composite time-frequency distribution (TFD) constructed using a multiple-view approach. This composite TFD utilises the intrinsic mode functions (IMFs) of the empirical mode decomposition (EMD) ...
Detecting Fetal Movements Using Non-Invasive Accelerometers: A Preliminary Analysis
(
IEEE
, 2010 , Article)
Monitoring fetal movement is important to assess fetal health. Standard clinical fetal monitoring technologies include ultrasound imaging and cardiotocography. Both have limited prognostic value and require significant ...
Accurate and efficient implementation of the time–frequency matched filter
(
Institution of Engineering and Technology
, 2010 , Article)
The discrete time-frequency matched filter should replicate the continuoustime-frequency matched filter, but the methods differ. To avoid aliasing, thediscrete method transforms the real-valued signal to the complex-valued ...
Automatic seizure detection based on the combination of newborn multi-channel EEG and HRV information Advances in Nonstationary Electrophysiological Signal Analysis and Processing
(2012 , Article)
This article proposes a new method for newborn seizure detection that uses information extracted from both multi-channel electroencephalogram (EEG) and a single channel electrocardiogram (ECG). The aim of the study is to ...
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 ...
