Charles François (systems scientist) Cybernetics Sciences)Honorary President of the Latin American Association of Systemics (ALAS), Honorary Professor of ITBA, Buenos Aires, and was visiting Professor at various universities and educational institutions in Argentina, Perú and Brasil. He became a member of systemic boards and integrated the editorial boards of various journals on Systems and Cybernetics. In 2007 he received from the American Society for Cybernetics, the Norbert Wiener golden medal as a tribute for his work on cybernetics. In 1952 François came in contact with cybernetics through Norbert Wiener's "Cybernetics". In 1958 he joined the Society for General Systems Research now the International Society
Wiener–Hopf method Wiener–Hopf method The Wiener–Hopf method is a mathematical technique widely used in applied mathematics. It was initially developed by Norbert Wiener and Eberhard Hopf as a method to solve systems of integral equations, but has found wider use in solving two-dimensional partial differential equations with mixed boundary conditions on the same boundary. In general, the method works by exploiting the complex-analytical properties of transformed functions. Typically, the standard Fourier transform is used, but examples exist using other transforms, such as the Mellin transform. In general, the governing equations and boundary conditions are transformed and these transforms are used to define
