Rational functions, despite limitations in differential modeling, enhance map quality by capturing complex structures without numerical issues during iteration. This method was successfully applied to copper electrodissolution data.

Area of Science:

  • * Mathematical Modeling
  • * Chemical Engineering

Background:

  • * Rational functions are typically avoided for global differential models due to poles causing trajectories to diverge.
  • * Existing modeling techniques may struggle with complex structures generated by maps.

Purpose of the Study:

  • * To demonstrate the utility of rational functions for improving map-based models.
  • * To explore the application of rational functions in analyzing experimental data.

Main Methods:

  • * Iterative modeling using rational functions.
  • * Application to experimental data from copper electrodissolution.

Main Results:

  • * Rational functions significantly improve the quality of models for maps.
  • * The presence of poles in rational functions does not cause numerical difficulties during model iteration.
