For the coffee fruit-stem system, by means of dynamic vibration tests, it was determined the following modal parameters: damped oscillation period, damping ratio, undamped and damped natural frequencies, damping coefficient, and stiffness of the system.
The simulation results can be expressed as the coordinated control of PSS and LOC made faster oscillations are damped oscillation damping and transient stability of power system dynamics quickly recover.

Using the values of parameters a and b, the type of economic fluctuation in each cluster was identified as summarized in Table 3 where three fluctuation patterns are observed: monotonic explosion (MO), explosive oscillation (EO), and damped oscillation (DO).
However, these physically real numbers are complex only for the period of damped oscillation processes.
A very useful device that is almost unknown in the United States, but has long been used in Japan is the FDOM (free damped oscillation method, also called pendulum-damping).
Beyond the first two years, this damped oscillation can be represented by the function (1)

In either case this fact implies that orbits near the equilibrium have either a "period two" damped oscillation or an aperiodic damped oscillation (except for a most a two-dimensional manifold of orbits embedded in three-dimensional phase space).
Application of NOTAR and fenestorn system, as well as the system concerning the problem of damped oscillation of engine, resulted with significant decrease of the noise level emitted by the helicopter during its flight.
