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
Carl Adam Petri a member of the Academia Europaea. Petri's work significantly advanced the fields of parallel computing and distributed computing, and it helped define the modern studies of complex systems and workflow management systems. His contributions have been in the broader area of network theory which includes coordination models and theories of interaction, and eventually led to the formal study of software connectors. Petri was honored with the following awards: Carl Adam Petri Carl Adam Petri (12 July 1926 – 2 July 2010) was a German mathematician and computer scientist. He was born in Leipzig. Petri created his major scientific contribution, the
