THE STEFAN PROBLEM WITH KINETIC FUNCTIONS AT THE FREE BOUNDARY
This paper considers a class of one-dimensional solidification problem in which kinetic undercooling is incorporated into the temperature condition at the interface. A model problem with nonlinear kinetic law is considered. The main result is an existence theorem. The mathematical effects of the kinetic term are discussed
متن کاملDetecting the location of the boundary layers in singular perturbation problems with general linear non-local boundary conditions
Singular perturbation problems have been studied by many mathematicians. Since the approximate solutions of these problems are as the sum of internal solution (boundary layer area) and external ones, the formation or non-formation of boundary layers should be specified. This paper, investigates this issue for a singular perturbation problem including a first order differential equation with gen...
متن کاملThe Study of Some Boundary Value Problems Including Fractional Partial Differential Equations with non-Local Boundary Conditions
In this paper, we consider some boundary value problems (BVP) for fractional order partial differential equations (FPDE) with non-local boundary conditions. The solutions of these problems are presented as series solutions analytically via modified Mittag-Leffler functions. These functions have been modified by authors such that their derivatives are invariant with respect to fractional deriv...
متن کاملA Look at the Challenges of Boundary-Spanner Academic Leaders
The present study was an exploratory sequential mixed method approach, so the qualitative section of the study was done by descriptive phenomenology method. The participants in the qualitative section included academic administrators with managerial experience who by criterion sampling and saturation in the research findings, 12 were selected for the interview. Research tools in the section wer...
متن کاملBoundary spanning in the context of academic education
Despite the emergence of the concept of boundary spanning in the fields of behavioral psychology and organization theories, this concept is still somewhat unknown in the health and medical education system. Meanwhile, one of the approaches and activities that can help to improve the health and medical education system is boundary spanning activities. Thus, boundary spanning is considered as a v...
