Carbon Data Assimilation Using an Ensemble Kalman Filter
… ratio assimilation capability in an ensemble Kalman filter (EnKF) data assimilation system with the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem). In spite of its global coverage, the CO retrievals from the Measurements Of Pollution In The Troposphere (MOPITT) …

Application of the extended Kalman filter to enzyme reactions
… estimate the bioprocess parameters. The use of filtering theory for state estimation provides a means of incorporating a deterministic model into a method of forecasting future states which includes the probabilistic uncertainties of both the system and the measuring devices. The state …

Fault monitoring in hydraulic systems using unscented Kalman filter
… monitoring scheme based on the Unscented Kalman Filter (UKF) is developed. In simulations, both measurement and process noises are considered. The results show that the algorithm estimates the iii system states with acceptable residual errors. Therefore, the structure is verified to be …

Exact Maximum Likelihood Estimation of the Kalman Filter Model
The interpretation of the Kalman filter model (KFM) used in this thesis is one where the transition equation allows the coefficients of a regression equation to follow an autoregressive-moving average process. Thus the KFM is a generalization of the random coefficients model.

Source localization of MEG generation using spatio-temporal Kalman filter
… observation equation, we derive spatio-temporal Kalman filter and fixed-interval smoothing algorithms for MEG source localization.To compare the methods analytically, we present a Bayesian derivation of the regularized least squares and Kalman filtering methods. This analysis reveals that the …

Identification of civil structural parameters using the extended Kalman filter
… is to evaluate the tracking ability of the Kalman filter for identifying civil structural parameters based on measured vibration data which usually are earthquake accelerations. For linear elastic structures, the ordinary Kalman filter was used, but for nonlinear elastic structures, we …

Maximum Power Point Tracking Using Kalman Filter for Photovoltaic System
… method for photovoltaic (PV) systems using Kalman filter. The Perturbation & Observation (P&O) method is widely used due to its easy implementation and simplicity. The P&O usually requires a dithering scheme to reduce noise effects, but the dithering scheme slows the tracking response time. …

Study of the Kalman filter for arrhythmia detection with intracardiac electrograms
… technique has been developed with the use of Kalman filter applied on cyclostationary autoregressive model. This new algorithm was developed with a training set of 24 arrhythmia passages and tested on a different data set of 29 arrhythmia passages. The algorithm provides 100% detection of VF …

Development of An Adaptive Kalman Filter for Estimation in Chemical Plant.
The application of the Kalman Filter to the on-line estimation of the state of a chemical process has so far met with a limited amount of success due to the inaccuracies and non-linearities of the mathematical models developed to describe the process being studied. To overcome these problems, two …

Estimating value at risk and expected shortfall: a kalman filter approach
… market risk and associated measures. A Kalman filter is used for the first time to estimate both VaR (and ES) to provide an alternative technique to existing industry methods. Modelling the volatility of asset returns as a stochastic process, the Kalman filter uses Bayesian statistics to …
