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 ...
An FPGA implementation of 2-D CNN Gabor-type filter
(IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2007)
A field programmable gate array (FPGA) implementation of the Gabor-type filter is presented. The implementation uses the forward Euler approximation with optimal step size to solve the CNN cell-state equation. The FPGA is ...
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. ...
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 ...
Aircraft sensor fault detection based on unknown input observers
(Emerald Group Publishing Limited, Howard House, Wagon Lane, Bingley Bd16 1Wa, W Yorkshire, England, 2008)
Purpose - The purpose of this paper is to generate residuals which can be used to detect fault and isolate on a vertical takeoff and landing (VIOL) aircraft dynamic model.
Design/methodology/approach - In the proposed ...
Four-quadrant switch-mode gyrator
(IEEE, 2008-05-23)
A gyrator design based on an inductor coupled double bridge converter is presented. It is shown that this gyrator can operate in four-quadrant mode by using bi-directional MOS switches without the necessity of any feedback ...
3-Phase Induction Motor Drive with PWM Modulator Using a 8-Bit Low Cost Micrcontroller
(2004)
This paper describes a study on a well studied subject, driving 3-phase induction motor. But the hardware used for the study is different than the conventional 16-bit microcontrollers or DSPs. The aim of the project is to ...
