Abstract: We use the sixth-order linear parabolic equation $$\begin{aligned} \frac{\partial y}{\partial t}=B\left( \alpha \frac{\partial ^{6}y}{\partial x^{6}}-\frac{\partial ^{4}y}{\partial x^{4}}\right) ,\ x\in {\mathbb {R}}_{+},\ t>0, \end{aligned}$$ proposed by Rabkin and describing the evolution of a solid surface covered… read more here.

Abstract: Abstract Grain boundaries are potential sites for the development of morphological instabilities along a solidifying interface, and plays an important role in the microstructural properties of cast alloys. In the present study, we employ a… read more here.
