Parameter specific optimal experiments are designed to maximize sensitivity and simultaneously minimize interactions and unwanted contributions by other parameters. Experiments are defined using only three design variables making our approach computationally efficient.
Summary and conclusion The presented global optimal experiment design (OED) method includes three main contributions to parametrization of electrochemical models: Firstly, a global sensitivity approach is used and therefore no accurate initial guess for the parameter vector is required.
Parameter estimates were several orders of magnitude away from nominal values, corroborating the need for global sensitivity for optimal experiment design. Secondly, we directly use Sobol indices to determine experiment optimality.
SA determines the impact of individual parameters for a given experiment . Previous model-based experiment design studies by Pozzi et al. , Park et al. and Forman et al. use a local SA which investigates perturbations around a nominal parameter vector θ.
Parameter optimization After experiments are established and carried out, parameter optimization minimizes residuals between experiment and model. We define a least-squares minimization problem as in Eq. (49) where θl and θu are the lower and upper constraint vectors equivalent to ranges given in Table 6.
Note that the number of experiment design variables m directly corresponds to the dimension of the outer OED optimization problem and therefore has large impact on the computational cost. It is essential that the proposed algorithm is equipped to excite all model parameters that are relevant under the expected usage conditions.

Melting points are often used to characterize organic and inorganic crystalline compounds and to ascertain their purity. Pure substances melt at a sharp, highly-defined temperature (very small temperature range of 0.5 – 1 °C) whereas impure, contaminated substances generally exhibit a large melting interval.

The structure of a substance affects its properties, and this is also true for chocolate. In this experiment, students explore what happens to chocolate when it is melted and allowed to reharden, testing the taste, texture and melting point of the chocolate to determine how these properties have changed as a result of the change in structure.
