Beta parameter interfaces

Under a pressure between 10 and lO Pa, and at a temperature in the 300 to 600°C range, analysis of the complex impedance spectrums show that, whatever the studied material (beta-alumina, glass, zirconia), oxygen pressure does not influence at all the parameters T and n which characterize the electrode-material interface. The capacitive effect and charge carrier diffusion in the material stay the same under all oxygen pressme values. 

As already mentioned, the perturbation of the input space, through the initial conditions (parameters) affected by uncertainties, needs to be performed by the proper distribution functions. RAVEN provides, through an interface to the BOOST library, the following univariate (truncated and not) distributions Bernoulli, Binomial, Exponential, Logistic, Lognormal, Normal, Poisson, Triangular, Uniform, Weibull, Gamma, and Beta. 

It is easier to see what experiments should be done in the electrode kinetic regime. Some basic electrode kinetics at polymer-solution interfaces must be measured - and this has not been successfully done. Thus, with the typical redox reactions of the ferrous/ferric type, it is important to establish Tafel parameters, particularly the parameter beta, and exchange current densities and rate constants.
