Conditional probability distributions INDEX

As we have already mentioned in Section 2, in OCT the complementary quantities characterizing the average noise (conditional entropy of the channel output given input) and the information flow (mutual information in the channel output and input) in the diatomic communication system defined by the conditional AO probabilities of Eq. (48) provide the overall descriptors of the fragment bond covalency and ionicity, respectively. Both molecular and promolecular reference (input) probability distributions have been used in the past to determine the information index characterizing the displacement (ionicity) aspect of the system chemical bonds [9, 46-48]. 

To establish [5] the thermodynamic meaning of the index of probability r/ = (ip — H)/9, it is assumed that the distribution g = ev changes as the condition of the system changes, but always subject to the normalization condition f evdfl = 1. It follows that the derivative d f evdQ, = 0. It is assumed that both 9 and tp, as well as extensive parameters may be altered, such that... 

From a product standpoint, the major benefit of the melt transesterification approach is that it produces resin with a most probable (thermodynamic) molecular weight distribution. Hence, under normal processing conditions, the anhydrous resin exhibits no tendency to change molecular weight or the melt flow index (MFI) (via redistribution).
