This paper is divided in two sections. The first one gives a procedure for the design of grounding systems, demonstrating the need of considering more complex soil structures, as the two layers soil model, in the design of safety grounding grids. The second section presents a transient model of a buried electrode based on the transmission line approach. The model enables to take into account th...

The periodic and random variations in human heart rate are physiologically and clinically significant. A wide variety of signal processing techniques have been applied to heart rate time series to extract information regarding heart rate variability. The heart rate response to a startling auditory stimulus is a useful measure of an individual's cardiovascular reactivity and may be related to th...

This paper presents time-frequency multiresolution wavelet analysis on power system transients. Since it is difficult to analyze transients on-site due to a vast amount of data recorded from a digital transient recorder, it is imperative to develop an intelligent recorder which has the ability to detect and classify different types of power system transients. In order to develop a good approach...
