Unlabelled:
To analyze the dynamic characteristics of the postural sway measurements, the curves of the velocity and acceleration of the postural sway measurements were used.
Method:
The curves of smoothed velocity and acceleration were got through the filter of Haar wavelet packet decomposing function.
Result:
At the increasing of age, the velocity and acceleration of the postural sway measurements are increasing, but they decrease when the noise are introduced.
Summary:
For those non-stochastic signals of certain physical explanation, the context method is suitable for analyzing the status of dynamic system.

Feedback control systems
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...
