Simulations

This is the real treasure-trove of the site. Here you can download all (well, most) of the simulations I ran in the course of the dissertation. These simulations required years of processor time, and I kept 20 processors busy at our high performance computing facility for the better part of 2008.

The files here should not be hard to use, but using them will require a lot of specific knowledge. You'll probably need to read all of the subitems under the “Simulations” menu before you'll be able to do anything. Also, most of the descriptions of what the batch jobs are won't make sense out of the context of chapters 5 and 6 of the dissertation.

Description of the batch runs

Here is a description of all of the batch runs that I used in the dissertation.

In all of the batch simulations, I never ran the “null” simulation, where no muscle was active. That explains why, e.g., Batch19 has only 127 postures, when 2^7=128. Actually I didn't include the rest posture in my components analyses...

I hope you won't assume that because these batch runs begin with 19, that I botched the first 18 runs...

Note on D3 and Batch27

D3 will be a tricky batch to reassemble, since to save computational time I took postures from a number of other batches. D3 is the set of all the combinations of the 14 postures associated with the activation patterns in Table 5.7, plus the 14 postures that result from having Table 5.7's postures in the left side of the tongue, plus the 14 postures that result from having Table 5.7's postures in the right side of the tongue. These postures are drawn from these batches:
  • Fourteen of the 196 postures are symmetrical; these are drawn from Batch19 and Batch20.
  • The 14 postures that result from having Table 5.7's postures in the left side of the tongue are drawn from Batch24 and Batch25.
  • The 182 (=196-14) postures that are assymetrical are the first 182 postures in Batch27.
  • The 14 postures that result from having Table 5.7's postures in the right side of the tongue are the last 14 postures from Batch27.
