Assuming that a time series incorporates 'signal' and 'noise' components, we propose a method to estimate the extent of the 'noise' component by considering the smoothing properties of the state-space of the time series. A mild degree of smoothing in the state-space, applied using a Kalman...

The main objective of this work is to determine the reading performance of operators' under different viewing angles of a desktop computer. The effects of text/ background color, viewing distance and character size on the speed of reading were investigated. The text and/or the background color...
