Nonlinear normal modes and spectral submanifolds: Existence, uniqueness and use in model reduction
, 2016 We propose a unified approach to nonlinear modal analysis in dissipative oscillatory systems. This approach eliminates conflicting definitions, covers both autonomous and time-dependent systems, and provides exact mathematical existence, uniqueness and ...

Theory of hydromagnetic turbulence [PDF]
, 1983 The present state of MHD turbulence theory as a possible solar wind research tool is surveyed. The theory is statistical, and does not make statements about individual events.

Nonlinear normal modes of a two degree of freedom oscillator with a bilateral elastic stop [PDF]
, 2012 A study of the non linear modes of a two degree of freedom mechanical system with bilateral elastic stop is considered. The issue related to the non-smoothness of the impact force is handled through a regularization technique.

Bifurcations in unsteady aerodynamics-implications for testing [PDF]
The various forms of bifurcations that can occur between steady and unsteady aerodynamic flows are reviewed. Examples are provided to illustrate the various ways in which bifurcations may intervene to influence the outcome of dynamics tests involving ...
