Publisher description for Duffing Measure Model

Duffing Measure Model program icon

The Ejs Duffing Measure model computes the solutions to the non-linear Duffing Equation, which reads, x'' + 2??x' - x (1 - x2) = f cos(?? t), where each prime denotes a time derivative. The simulation displays the evolution of a group of oscillators with Similar initial parameters on a Poincare plot and the evolution of the oscillator with the central initial parameter displayed on a separate Poincare plot. 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 Measure 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_measure.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.
