Green's functions and propagators for the multi-dimensional anisotropic space-time fractional diffusion equation are obtained in integral form. Uniqueness of the solutions is studied in the framework ...

In this article, we discuss the laser flash diffusivity method’s working principle, applications, its advantages over other methods, and finally its limitations and research directed towards ...

“However, to compare model predictions with empirical observations, one needs to study the diffusion equation in finite space. Despite the work of illustrious scientists such as Smoluchowski, Pólya, ...

Thermal diffusivity is a measure of the speed at which heat propagates in a medium by conduction when the temperature varies with time. It is a thermophysical property whose value is directly ...

Mountain permafrost is warming and thawing worldwide due to climate change, with ground temperature being a key control of ...
