Talcott Parsons science. Parsons also became strongly interested in systems theory and cybernetics and began to adopt their basic ideas and concepts to the realm of social science, especially the work of Norbert Wiener (1894–1964) had his attention. Some of the students who arrived at the Department of Social Relations in the years after the Second World War were David Aberle, Gardner Lindzey, Harold Garfinkel, David G. Hays, Benton Johnson, Marian Johnson, Kaspar Naegele, James Olds, Albert Cohen, Norman Birnbaum, Robin Murphy Williams, Jackson Toby, Robert N. Bellah, Joseph Kahl, Joseph Berger, Morris Zelditch, Renee Fox, Tom O'Dea, Ezra Vogel, Clifford Geertz,
Wiener series by Norbert Wiener used in signal processing. Given a system with an input/output pair formula_1 where the input is white noise with zero mean value and power A, we can write the output of the system as sum of a series of Wiener G-functionals formula_2 In the following the expressions of the G-functionals up to the fifth order will be given: formula_3 formula_4 formula_5 formula_6 formula_7 formula_8 formula_9 formula_10 formula_11 Wiener series In mathematics, the Wiener series (or "Wiener G-functional expansion") originates from the 1958 book of Norbert Wiener. It is an orthogonal expansion for nonlinear functionals closely related to
