Center manifolds for evolution equations associated with the Stefan problem [PDF]
, 2017 Evolution equations can be used for solving the Stefan problem. We show the existence of a center manifold for an evolution equation that is associated with a quasilinear Stefan problem with variable surface tension and undercooling.

, 2000 A Stefan problem associated with the Burgers equation is considered. The problem is reduced to a nonlinear integral equation which is analysed and shown to have a unique solution. The system admits a shock solution which travels with the same velocity as

Localizing value of cutaneous ictal phenomena: A systematic review
Epileptic Disorders, EarlyView.Abstract Objective Clinical observation of autonomic signs during seizures can aid in localizing the epileptogenic zone (EZ). We performed a systematic review and meta‐analysis to evaluate the localizing value of ictal cutaneous phenomena—piloerection, sweating, pallor, and flushing—in focal epilepsy and their relevance to presurgical evaluation ...

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018 The optimal control of moving boundary problems receives growing attention in science and technology. We consider the so called two-phase Stefan problem that models a solid and a liquid phase separated by a moving interface. The Stefan problem is coupled

Energy Science &Engineering, EarlyView.Passing vehicles generate short‐duration wakes that can be redirected toward a vertical‐axis turbine. The interaction between wake structure, blade count, and rotational speed governs transient torque production. Low‐solidity configurations combined with tuned rotational speed enhance energy extraction under vehicle‐induced gusts.

Some remarks on the Stefan problem with surface structure
, 2018 : "This paper discusses a generalized Stefan problem which allows for supercooling and superheating and for capillarity in the interface between phases. Simple solutions are obtained indicating the chief differences between this problem and the classical

Self-similar solutions of a multi-phase Stefan problem on the half-line
Современная математика: Фундаментальные направленияIn this paper, we study self-similar solutions of the multiphase Stefan problem for the heat equation on the half-line x 0 with constant initial data and Dirichlet or Neumann boundary conditions. In the case of the Dirichlet boundary condition, we prove
