In this paper, a framework for diffusion of color images is presented. The method is based on the theory of thermodynamics of irreversible transformations, which provides a suitable basis for designing correlations between the different color channels. More precisely, we derive an equation for color evolution, which comprises a purely spatial diffusive term and a nonlinear term that depends on ...

We study in this paper the well-posedness and stability of a linear system thermoelastic Cosserat medium with infinite memory, where is continuum which each point has degrees freedom rigid body.

The problem treated here is to determinethe viscosity effect on stresses, temperature change and chemical potential in a circular plate. The mathematical formulation is applied to two theories of thermoelastic diffusion developed by Sherief et al. [27] with one relaxation time and Kumar and Kansal [9]with two relaxation times. Laplace and Hankel transform techniques are used to obtain the expre...
