A Method for Determining the Transient Process Duration in Dynamic   Systems in the Regime of Chaotic Oscillations
  We describe a method for determining the transient process duration in a standard two-dimensionaldynamic system with discrete time (Henon map), occurring in the regime of chaotic oscillations
