Empirical Mode Decomposition
Group Members: Max Lambert, Andrew Engroff, Matt Dyer, Ben Byer

   Synthetic vs. Natural
   MATLAB Code

Input of each group member:

  • Max Lambert
    • General: MATLAB code "tweaking", found natural signal
    • Poster: Process section, editing
  • Andrew Engroff
    • General: Natural signal found, tested, and analyzed
    • Poster: Overview section, design/layout
    • Web: Design and text
  • Matt Dyer
    • General: Synthesized signal testing and analysis
    • Poster: Conclusion section, editing
    • Web: Plots and MATLAB code
  • Ben Byer
    • General: Found MATLAB code for EMD
    • Poster: Basic outline, some miscellaneous information, printing
    • Web: Comparison of EMD algorithm using different parameters (missing)
  • Each group member learned enough of the topic to be helpful in presenting the material at the session, but physical work was split up as above.
