This paper considers estimation of an unknown state function in the heat equation with state-dependent parameter values. The work is motivated by phase transitions in physical media, e.g., thawing of water or foodstuff, welding and casting processes. We point out that known solution to standard Stefan problem solutions can be recovered with this formalism, and then propose a simple phase transition estimator that relies only on boundary measurements. Simulations indicate that the estimates converge for noise-free measurements.
