Case studies across engineering

The lectures carry their ideas on a few datasets chosen to run through the course: an air-quality sensor network, a lab of wireless motes, a simulated chemical plant, concrete mixes, and turbofan engines. The ideas themselves belong to no single field. A split that leaks information inflates accuracy just as much for heartbeats as for engines. A seasonal effect hides damage in a bridge the way drift hides a fault in a sensor.

Each page in this section takes one documented case from another branch of engineering and reads it through the lectures. Every case rests on published work, every number on these pages was checked against its source, and every page links back to the sections of the notes it illustrates. They are optional reading. Pick the ones closest to your own field, or the ones that cover an idea you found hard in class.
