Classical phenomenological model of diffusion in fluids is based on the concept of the mean-free-path, λ, and density distribution, n(x,t), as a function of coordinate, x, and time, t. Under the assumption that(1)n(x-λ,t)-n(x+λ,t)≈-2λ(∂n/∂x),this model results in the classical...

This paper provides a systematic methodology to identify general innovation diffusion patterns in a given case study: First, an analytical framework is introduced which structures a review of innovation diffusion research. This framework may be used to structure the analysis of a case study....
