Square-root-calculating circuits find wide use in instrumentation and measurement systems for such tasks as calculating the rms (root-mean-square) value of an arbitrary waveform, for example. Hence, ...

The first time I was in school for electrical engineering (long story), I had a professor who had never worked in the industry. I was in her class and the topic of the day was measuring AC waveforms.

The Gaussian form chosen for the variogram in the "Getting Started" section is based on the consideration of the plots of the sample variogram. For the coal thickness data, the Gaussian form appears ...
