Explanation of the Image...

This image created with the spectrum intercept algorithm is based on the dynamical system characterized by the expression
where x'' is the second derivative of x with respect to time, t, and |x| is the absolute value of x.

The domain of this image in the map of possible states for this system is,
(-6.491, 11.1)/(4.0, -6.6).

The parameter values are a=7.5, ω=1, φ=0, b=1 and μ=0.1.
