This paper presents a fractional mathematical model of a one-dimensional phase-change problem (Stefan problem) with a variable latent-heat (a power function of position). This model includes space–time fractional derivatives in the Caputo sense and time-dependent surface-heat flux. An approximate solution of this model is obtained by using the optimal homotopy asymptotic method to find the solu...

Analytic interpolation problems with rationality and derivative constraints are ubiquitous in systems control. This article provides a new method for such problems, both the scalar matrix case, based on nonstandard Riccati-type equation. The rank of solution is same as degree interpolant, thus providing natural approach to model reduction. A homotopy continuation presented applied some modeling...
