Could anyone with access to IEICE or CiNii get this PDF?
T. L. Nwe, F. S. Wei, and L. C. De-Silva. "Stress classification using subband based features."
Here are the only two places I've found it available:

I've got two differing versions of an equation in two newer papers by the same authors, so I'm hoping this one will clear it up!
