For a proper operation the spraying machines must be tested to establish the parameters for pumps. These papers are presented the results of a test on a piston pump, mounted on the EEP-600 ME spraying machine. It is also shown how the pump flow is mo

A method for single-trial estimation of multichannel evoked potentials is presented. The proposed method is based on the regularized least squares scheme. The spatial correlation between the channels is used as additional information in the estimatio

An advanced, simple to use, detrending method to be used before heart rate variability analysis (HRV) is presented. The method is based on smoothness priors approach and operates like a time-varying finite-impulse response high-pass filter. The effec

EP research has to deal with several inherent difficulties. Traditional analysis is based on averaged data often by forming extra grand averages of different populations. Thus, trial-to-trial variability and individual subject characteristics are lar

A mathematical way to describe trial-to-trial variations in evoked potentials (EPs) is given by state-space modeling. Linear estimators optimal in the mean square sense can then be obtained through Kalman filter and smoother algorithms. Of importance
