Norbert Wiener the amount of noise present in a signal by comparison with an estimate of the desired noiseless signal. Wiener developed the filter at the Radiation Laboratory at MIT to predict the position of German bombers from radar reflections. It is necessary to predict the future, because by the time the shell reaches the vicinity of the target, the target has moved, and maybe has changed direction slightly. They even modeled the muscle response of the pilot, which led eventually to cybernetics. The unmanned V1's were particularly easy to model, and on a good day, American guns fitted with Wiener filters
Mathematics and Mechanics of Complex Systems Mathematics and Mechanics of Complex Systems Mathematics and Mechanics of Complex Systems (MEMOCS) is a half-yearly peer-reviewed scientific journal founded by the International Research Center for the Mathematics and Mechanics of Complex Systems (M&MoCS) from Università degli Studi dell'Aquila, in Italy. It is published by Mathematical Sciences Publishers, and first issued in February 2013. The co-chairs of the editorial board are Francesco dell'Isola and Gilles Francfort, and chair managing editor is Martin Ostoja-Starzewski. "MEMOCS" is indexed in Scopus, MathSciNet and Zentralblatt MATH. It is open access, free of author charges (being supported by grants from academic institutions), and available in
