Several versions of free-volume theory have been proposed to correlate or predict the solvent diffusion coefficient of a polymer/solvent system. The quantity of free volume is usually determined by the Williams-Landel-Ferry (WLF) equation from viscosity data of the pure component in these theories.
A methodology for predicting the probability of human task reliability during a task sequence is described. The method is based on a probabilistic performance requirement-resource consumption model. This enables error-promoting conditions in accident scenarios to be modelled explicitly and a time-de
