Sorted by: Date Added To NTRS in Descending order Transfer Functions Via Laplace- And Fourier-Borel Transforms Author(s): Can, Sumer; Unal, Aynur Abstract: Approach to solution of nonlinear ordinary differential equations involves transfer functions based on recently-introduced Laplace-Borel and Fourier-Borel transforms. Main theorem gives transform of response of nonlinear ... NASA Center: Ames Research Center Publication Year: 1991 Added to NTRS: 2005-09-30 Accession Number: 91B10485; Document ID: 19910000485; Report Number: ARC-12295 Transfer functions for nonlinear systems via Fourier-Borel transforms Author(s): Can, Sumer; Unal, Aynur Abstract: An analytical functional can be expressed as a sum of some nonlinear functional expansions which we shall call Fliess's generalized expansions. These nonlinear functional expansions are analogous to Fourier series or ...

V.; Unal, Aynur; Tobak, M. Abstract: Various features of the solutions of Duffing's equation are described using a representation of the solutions in the Laplace-Borel transform domain. An application of this technique is illustrated for the symmetry-breaking ...
