Dual Kalman Filter based State-Parameter Estimation in Linear Lung Models
(Springer, 233 Spring Street, New York, Ny 10013, United States, 2009)
Time-domain approach to inverse modeling of respiratory system requires estimation of the parameters from the noisy observation. In this work, states and parameters of the linear lung models are estimated simultaneously ...
Generalized Gauss Distribution Noise Model for Respiratory Parameter Estimation
(Ieee, 345 E 47Th St, New York, Ny 10017 Usa, 2009)
In this studs, measurement noise is modelled as a Generalized Gauss Distribution and a new method is presented to estimate the model parameters. The estimator algorithm consists of the Kurtosis method, Kalman iterarions ...
Application of Stockwell Coherence To Prediction Of Alertness Under Anaesthesia
(Brno Univ Technology Vut Press, Purkynova 118, Brno 61200, Czech Republic, 2010)
In this paper, we represent an application of Stockwell Coherence to scalp EEG signals under anesthesia. By the analysis of overlapping, stationary data segments, we obtained the time-varying Stockwell coherence, which ...
Posterior Cramer-Rao Lower Bounds for Dual Kalman estimation
(Academic Press inc Elsevier Science, 525 B St, Ste 1900, San Diego, Ca 92101-4495 USA, 2012-01)
We present the Posterior Cramer-Rao Lower Bounds (PCRLB) for the dual Kalman filter estimation where the parameters are assumed to be time-invariant and stationary random variables. Relations between the PCRLB, the states, ...
RESPIRATORY PARAMETER ESTIMATION IN LINEAR LUNG MODELS
(IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2008)
If the respiratory system Is represented as a one compartment model composed of linear electrical elements, the Minimum Variance Unbiased Estimation (MVUE) Is the optimum statistical method to estimate the model parameters. ...
Inverse Modeling of Respiratory System during Noninvasive Ventilation by Maximum Likelihood Estimation
(Hindawi Publishing Corporation, 410 Park Avenue, 15Th Floor, #287 Pmb, New York, Ny 10022 Usa, 2010)
We propose a procedure to estimate the model parameters of presented nonlinear Resistance-Capacitance (RC) and the widely used linear Resistance-Inductance-Capacitance (RIC) models of the respiratory system by Maximum ...
Lung Sound Noise Reduction Using Gabor Time-Frequency Masking
(SPRINGER-VERLAG BERLIN, HEIDELBERGER PLATZ 3, D-14197 BERLIN, GERMANY, 2007)
The Gabor expansion is a mathematical tool, which provides a joint time-frequency representation of a given signal by decomposing it into time-frequency elementary signals called Gabor atoms. It has been used in a variety ...
Lung model parameter estimation by unscented Kalman filter
(IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2007)
Dynamic nonlinear models are the best choice to analyze respiratory systems and to describe system mechanics. In this work, Unscented Kalman Filtering (UKF) was used to estimate the dynamic nonlinear model parameters of ...
Fundamental Frequency Estimation for Monophonical Turkish Music by using VMD
(IEEE, 345 E 47Th St, New York, Ny 10017 USA, 2015-05-16)
In this study, a new method is presented for the fundamental frequency estimation of Turkish makam music recordings by using Variational Mode Decomposition (VMD). VMD is a method to decompose an input signal into an ensemble ...
Analysis of brain connectivity changes after propofol injection by generalized partial directed coherence
(Academic Press Inc Elsevier Science, 525 B St, Ste 1900, San Diego, Ca 92101-4495 Usa, 2014)
In this paper we present a method for the analysis of multichannel EEG by using Generalized Partial Directed Coherence (gPDC) to extract cortical connectivity changes under anesthesia. 15 channel EEG data were recorded ...
