Interactive Computer Graphics for Analysis and Design of Control Systems
A 1985 technical thesis from the Air Force Institute of Technology school of engineering, written by John R. Bullard and distributed through the Defense Technical Information Center, on interactive computer graphics for designing control systems. The pages are scanned typescript figures rotated sideways, showing flow-style block diagrams of circles linked by labelled arrows, with numbered nodes and short captions beneath; a designer could borrow the circle-and-arrow node layout as a plain schematic structure.
