Accelerometer-based fetal movement detection
(
IEEE
, 2011 , Conference Paper)
Monitoring fetal wellbeing is a compelling problem in modern obstetrics. Clinicians have become increasingly aware of the link between fetal activity (movement), well-being, and later developmental outcome. We have recently ...
Kalman filter-based time-varying cortical connectivity analysis of newborn EEG
(
IEEE
, 2011 , Conference Paper)
Multivariate Granger causality in the timefrequency
domain as a representation of time-varying cortical
connectivity in the brain has been investigated for the adult
case. This is, however, not the case in newborns as ...
A nonparametric feature for neonatal EEG seizure detection based on a representation of pseudo-periodicity
(
Elsevier Ltd
, 2011 , Article)
Automated methods of neonatal EEG seizure detection attempt to highlight the evolving, stereotypical, pseudo-periodic, nature of EEG seizure while rejecting the nonstationary, modulated, coloured stochastic background in ...
Editorial: Time-Frequency Approach to Radar Detection, Imaging, and Classification
(
Institution of Engineering and Technology
, 2010 , Article)
One of the central problems in exploiting the radar data is the analysis of atime series. The problem at hand is how to extract the information present in the data and use it to its full potential. Traditionally, radar ...
Wideband radar based fall motion detection for a generic elderly
(
IEEE Computer Society
, 2017 , Conference Paper)
Radar-based automated fall detection systems are considered as an important and emerging technology for elderly assisted living. These radar systems provide non-intrusive sensing capabilities to detect fall events. Various ...
An Improved Design of High-Resolution Quadratic Time-Frequency Distributions for the Analysis of Nonstationary Multicomponent Signals Using Directional Compact Kernels
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
This paper presents a new advanced methodology for designing high resolution time-frequency distributions (TFDs) of multicomponent nonstationary signals that can be approximated using piece-wise linear frequency modulated ...
Improving DOA Estimation Algorithms Using High-Resolution Quadratic Time-Frequency Distributions
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
This paper addresses the problem of direction of arrival (DOA) estimation and blind source separation (BSS) for nonstationary signals in the underdetermined case. These two problems are strongly related to the mixing matrix ...
Range-Doppler radar sensor fusion for fall detection
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
Falls are the major cause of accidents in the elderly population. Propelled by their non-intrusive sensing capabilities and robustness to heat and lighting conditions, radar-based automated fall detection systems have ...
Radar fall detectors: A comparison
(
SPIE
, 2016 , Conference Paper)
Falls are a major cause of accidents in elderly people. Even simple falls can lead to severe injuries, and sometimes result in death. Doppler fall detection has drawn much attention in recent years. Micro-Doppler signatures ...
Radar fall detection using principal component analysis
(
SPIE
, 2016 , Conference Paper)
Falls are a major cause of fatal and nonfatal injuries in people aged 65 years and older. Radar has the potential to become one of the leading technologies for fall detection, thereby enabling the elderly to live independently. ...
