I was looking for an efficient algorithm calculating variance of a sliding window of the last n values an ongoing signal, and this came up.

Besides the content of the paper, the metadata on page 2 is interesting, as well as the barcode on the front page as well as the machine readable font accompanying the bar code. Did not know that was a thing in 1969 but maybe it was attached later in time.
