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 ... -
Analysis of the time-varying cortical neural connectivity in the newborn EEG: A time-frequency approach
( IEEE , 2011 , Conference Paper)Relationships between cortical neural recordings as a representation of functional connectivity between cortical brain regions were quantified using different time-frequency criteria. Among these, Partial Directed Coherence ... -
An automatic time-frequency procedure for interference suppression by exploiting their geometrical features
( IEEE , 2011 , Conference Paper)This paper presents an adaptive method for interference suppression in the Wigner-Ville distribution. The structure of the artifacts in the Wigner-Ville distribution has been analyzed to optimally mask the signal Wigner-Ville ... -
Detection of seizure signals in newborns
( IEEE , 1999 , Conference Paper)This paper considers a system design for processing a multidimensional biomedical signal formed by EEG, ECG, EOG and motion recorded from a newborn, for the purpose of detection of epileptic seizures in newborns as an ... -
Fuzzy time domain and Z-transform for modeling of harmonic electric loads
( IEEE , 2001 , Conference Paper)This paper demonstrates the application of fuzzy systems and Z-transform for electric load modeling in the presence and/or absence of harmonics. The problem is formulated as one of linear optimization, where the objective ... -
Image quality metrics based multifocus image fusion
( IEEE , 2011 , Conference Paper)We describe an innovative methodology for block based multifocus image fusion in the spatial domain. The main idea is to use blind or no reference blur metrics for image fusion applications. Two blur quality metrics ... -
An improved method for nonstationary signals components extraction based on the ICI rule
( IEEE , 2011 , Conference Paper)This paper proposes an improved adaptive algorithm for components localization and extraction from a noisy multicomponent signal time-frequency distribution (TFD). The algorithm, based on the intersection of confidence ... -
Iterative learning control for variable frequency drives
( IEEE , 2008 , Conference Paper)Variable Frequency Drives (VFD) are subject to various types of disturbances especially cyclical ones. These periodic disturbances are difficult to compensate by conventional controllers. Repetitive control can only ... -
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 ... -
An open-loop technique for angle determination from position encoders
( IEEE , 2008 , Conference Paper)The paper presents a novel technique for the determination of the angle from low-frequency quadrature cosinusoidal signals produced, for example, by position sensors. In the presented scheme applied to a resolver, the ... -
A resolver converter based upon a novel open-Loop Technique
( IEEE , 2008 , Conference Paper)The paper presents a novel technique for the determination of the angle from slowly-varying quadrature co-sinusoidal signals produced, for example, by position sensors. In the presented scheme applied to a resolver, the ... -
Time-Frequency Characterization of Tri-Axial Accelerometer Data for Fetal Movement Detection
( IEEE , 2011 , Conference Paper)Monitoring fetal wellbeing is a significant problem in modern obstetrics. Clinicians have become increasingly aware of the link between fetal activity and its well-being. Using data acquired by accelerometry sensors, we ... -
Time-frequency signal and image processing of non-stationary signals with application to the classification of newborn EEG abnormalities
( IEEE , 2011 , Conference Paper)This paper presents an introduction to time-frequency (T-F) methods in signal processing, and a novel approach for EEG abnormalities detection and classification based on a combination of signal related features and image ... -
Voltage stability evaluation of real power transmission system using singular value decomposition technique
( IEEE , 2008 , Conference Paper)Voltage stability is an important factor that needs to be taken into consideration during the planning and operation of power systems in order to avoid voltage collapse and subsequently partial or full system blackout. ... -
Wireless transmission with cooperation on demand for slow and fast fading environments
( IEEE , 2008 , Conference Paper)Mobile users with single antennas can still take advantage of spatial diversity through repetition based cooperative transmission. In this paper, we consider a scheme in which the relay chooses to cooperate only if the ...
