It follows that important physical parameters of the (L-N-B)-model include 1. The average force constants of a L-N-B chain ... 

It is interesting to note that the (L-N-B)-model leads to similar expressions for the moduli like the VTG-model apart from the first summand of Eq. (38). However, contrary to the semi-empirical weighting functions W(y6) of the VTG-model, the corresponding density distribution function/la(y) in the (L-N-B)-model is related to the morphological structure of the filler network, i.e., the distribution of singly connected bonds in a percolation network. Unfortunately, this distribution function is not known, exactly. Therefore, a simple exponential... 

The (L-N-B)-model represents a highly sophisticated approach to the nonlinear behavior of dynamically excited, filled rubbers. However, it must be criticized that fittings of the storage - and loss - modulus could not be obtained with a single distribution function/la (y). The physical meaning of the density distribution function gla (y) remains unclear, indicating that the consideration of energy dissipation in the (L-N-B)-model is uncompleted.

In summary, at each iteration of the estimation method we compute the model output, y(x kw), and the sensitivity coefficients, G for each data point i=l,...,N which are used to set up matrix A and vector b. Subsequent solution of the linear equation yields Akf f 1 and hence k[Pg.53]

At this point we can summarize the steps required to implement the Gauss-Newton method for PDE models. At each iteration, given the current estimate of the parameters, ky we obtain w(t,z) and G(t,z) by solving numerically the state and sensitivity partial differential equations. Using these values we compute the model output, y(t k(i)), and the output sensitivity matrix, (5yr/5k)T for each data point i=l,...,N. Subsequently, these are used to set up matrix A and vector b. Solution of the linear equation yields Ak(jH) and hence k°M) is obtained. The bisection rule to yield an acceptable step-size at each iteration of the Gauss-Newton method should also be used.

Fig. 2. Log-logit plot of inhibition of HyHE1 5 binding to HEL by mutant lysozymes. The profile of cloned wild-type lysozyme (WT HEL) was not significantly different from that of native wild-type HEL. The reactivity of the R68K mutant was reduced by over 3 log units, similar to that seen previously with bobwhite quail lysozyme [T. B. Lavoie, L. N. W. Kam-Morgan, A. B. Hartman, C. P. Mallett, S.

Sercarz, eds.), p. 151. Adenine Press, Schenectady, New York, 1989], whereas R45K reduced reactivity by approximately 100-fold.
