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.
  • * The method effectively captures complex structures generated by maps.

Conclusions:

  • * Rational functions offer a viable approach for enhancing map-based models, overcoming limitations of traditional differential models.
  • * The technique is numerically stable and adept at capturing intricate data patterns, as shown in copper electrodissolution.
  • * This study highlights the potential of rational functions in scientific modeling and data analysis.
