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
ARC Centre for Complex Systems systems science is an emerging discipline developing new ways of investigating large, highly intricate, dynamically changing systems across diverse areas such as biology, social networks and socio-technological systems, economics and the environment. The ACCS was established to conduct world-class research on questions fundamental to understanding, designing and managing complex systems. While complex systems research is considered basic research, with commercialisation still some time off, complex computing holds answers to real-life systems. The ACCS provided a focus for complex systems science research in Australia, and developed strong infrastructure for modelling and analysing network-based systems, enabling the science to be applied to
