| 1. | The undamped Duffing equation is known to be a Hamiltonian system:
|
| 2. | But after years of hacking and duffing, I figured it out.
|
| 3. | It is a discrete version of the Duffing equation.
|
| 4. | The Duffing equation is an example of a dynamical system that exhibits chaotic behavior.
|
| 5. | That's why you see guys like John Huston duffing four shots off the ground.
|
| 6. | Munt ran into early trouble, duffing a chip from just off the second green and taking a bogey.
|
| 7. | Corrections can be made by " duffing " ( re-coating ) the scribe sheet with special duffing liquid.

| 8. | Corrections can be made by " duffing " ( re-coating ) the scribe sheet with special duffing liquid.
|
| 9. | Moreover, the Duffing system presents in the frequency response the jump resonance phenomenon that is a sort of frequency hysteresis behaviour.
|
| 10. | The Duffing equation can be seen as describing the oscillations of a mass attached to a nonlinear spring and a linear damper.
