was chown t o be i n i t i d l j Gaus>ian. I n Fig. 1 we see that the energy is given
correctly for moderate times for Re I 5. For larger Reynolds number,
thc representation is pooI. Even this achievement is noteworthy; a Reynolds
numhcr 5 gikes markedly nonlinear behavior in the initial stages of
the proces. I t is evident that the W H representation is capable of representing such nonlinear activity adequately by this energy criterion.
The use ofa time dependent base noticeably improves the situation as is seen
