Figure 5.37 Correlation dimension, d,, versus embedding dimension, m, defined in Appendix I,
for the system of Figure 5.30 at (a) U = 6.77ds; (b) U = 7.27ds; (c) U = 7.47ds. The
measurement error (68% confidence limit - see Appendix I) for convergent m (i.e. m 2 4) was
0.004 (Paidoussis, Cusumano & Copeland 1992). Note that u = l.l5[U(ds)].
