QFT = QFE for idiots. Devised by those who lack an understanding of the word "Emphasis". Quoted for Emphasis is essentially the same as Quoted for Truth, only it makes sense. If you are quoting something "for truth", you are quoting it for, get this - EMPHASIS.

'QFT' is usually used by children (i.e, under 13) who have clearly not had internet access long enough. Thus it is usually found on forums with something to do with children's games - namely CS, and various MMOs.

Quantitative Feedback Theory. It is a theory that describes the use of feedback for control systems. Many control engineering challenges were solved by means of these ideas. The godfather of QFT was Prof. Isaac Horowitz, continuing the work by H.W.Bode.
Flight Control Systems (FCS), wind turbines, smart structures, robotics... are practical examples of applications of QFT-based designs.
