Duffing - incoming phase problem

As we all know, Duffing equation go to grate scale period when incoming signal fit to some criterion (sinusoidal and amplitude of resulting signal must be greater than some constant - one can give constant from Lyapunov exponent method). In theory all seems great...

phrack 68, article 11

Interesting article in phrack))) I'd implement some sources

Duffing oscillator with GPS signal

I've read several articles about using chaos theory in GPS. One of them about using Duffing oscillator to detecting periodic signal. As you know GPS carrier is a periodic cosine signal.

Another kernel patch for fork-exit with cgroups
