History of computer science probability theory to the problem of how to best encode the information a sender wants to transmit. This work is one of the theoretical foundations for many areas of study, including data compression and cryptography . From experiments with anti-aircraft systems that interpreted radar images to detect enemy planes, Norbert Wiener coined the term cybernetics from the Greek word for "steersman." He published "Cybernetics" in 1948, which influenced artificial intelligence. Wiener also compared computation, computing machinery, memory devices, and other cognitive similarities with his analysis of brain waves. The first actual computer bug was a moth. It was stuck in
Wiener amalgam space formula_9, for all formula_10. Again, the space defined is independent of formula_8. As the definition suggests, Wiener amalgams are useful to describe functions showing characteristic local and global behavior. Wiener amalgam space In mathematics, amalgam spaces categorize functions with regard to their local and global behavior. While the concept of function spaces treating local and global behavior separately was already known earlier, Wiener amalgams, as the term is used today, were introduced by Hans Georg Feichtinger in 1980. The concept is named after Norbert Wiener. Let formula_1 be a normed space with norm formula_2. Then the "Wiener amalgam space" with
