Cobb–Douglas production function — A two input Cobb–Douglas production function In economics, the Cobb–Douglas f form of production functions is widely used to represent the relationship of an output to inputs. Similar functions were originally used by Knut Wicksell (1851–1926),… … Wikipedia
Modulation transfer function (infrared imaging) — The Modulation Transfer Function (MTF) is used to approximate the position of best focus of an infrared imaging system. In an imaging system, best focus is typically achieved when the MTF is between 0.4 and 0.6; most often at 0.5 (50% cutoff… … Wikipedia
