The Ejs Duffing Baker's Map model computes the solutions to the non-linear Duffing equation, which reads, x'' + 2γ x' - x (1 - x²) = f cos(ω t), where each prime denotes a time derivative.  The simulation displays N².  Poincare plots each separated by the same phase angle.  The evolution parameters can be changed via textboxes.  You can modify this simulation if you have Ejs installed by right-clicking within the plot and selecting "Open Ejs Model" from the pop-up menu item.  

Ejs Duffing Baker's Map model was created using the Easy Java Simulations (Ejs) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the ejs_ehu_chaos_Duffing_Baker.jar file will run the program if Java is installed.  Ejs is a part of the Open Source Physics Project and is designed to make it easier to access, modify, and generate computer models.  Additional Ejs models for non-linear dynamics and chaos are available.  They can be found by searching ComPADRE for Open Source Physics, OSP, or Ejs.
