Movies of plane Couette - tutorial

(latest posts at the top)


Check out Dynamical Systems Magazine: our tutorial is featured, with somewhat misleading abstract — Predrag Cvitanovic 2009-04-28

  • still need to finalize the world as seen from upper branch
    • need to include some eigenfunctions
  • continuation diagrams showing that solutions (EQBs and TWs) are robust under parametric perturbation
  • picture of HKW periodic orbits compared to HKW turbulence. JFG finds this one compelling.
  • need to add two slides to conclusions
    • eigenfunctions → control
    • Lagrangian chaos → turbulent mixing (maybe wait?)
  • to all: make sure flash pop-ups work in all of your browsers?
    • Mac? (which I do not have)
    • XPwindows Firefox 3.0+ OK
    • XPwindows IExplorer 7.0+ OK
    • Linux Firefox 3.0+ OK
    • manually-tuned Konqueror on OpenSUSE 11.1 OK/JFG
  • DONE: more movies of orbits; link to channelflow database and movie page — Predrag Cvitanovic 2009-03-25

English-major editing of tutorial. Mostly spelling, commas, and particles. A couple changes in sentence structure for flow. Changed Herr Turbulence Expert's Question to Objection, since it wasn't really a question. But Objection might be too aggressive, maybe change it back. Changes are obscured in diffs by very long lines of text and white-space changes due to trailing whitespace removal, which my editor now does for greater compatibility with other editors in other svn repos.

Have no objection to “Objection”

a morning's worth of polishing of the tutorial — Predrag 2009-02-26

  • finalized the explanation of the translational basis projection in
  • John, if you proofread this as English major (keep Gibson out of it for now), I'll go through the periodic orbits paper.


Firefox version seems OK, but have IExplorer woes: pop-ups OK when run locally, from the files on the computer, but ran from the webserver they come misformated, with all toolbars showing. What to do? — Predrag Cvitanovic 2009-02-27 03:07

:-? When I click in “video formats”, the following files do not exist

 (Quicktime .mov, h264 encoding, 18 MB)
 (Microsoft .avi, wmv2 encoding, 22 MB)
 (Xiph .ogg, theora encoding, 15 MB)

8-) thanks! fixed now — Predrag Cvitanovic 2009-02-03 02:47

Adding audio

8-) would be nice to add a narrative to some of the more difficult slides. As an example, here is Robert_Oppenheimer.ogg. It plays right away, embedded in my Firefox on XPwindows. The *.ogg players can be copied from its source file (have not done it yet). Check, and

To create an *.ogg, I use mswindows 'sound recorder' - that gives me a huge *.wav. file. Then I download OggDropXPd and drag the *.wav into its icon - result is an *.ogg file reduced by a factor of 20. ~~DISCUSSION~~
