Mathematical models for the description, in a quantitative way, of the damages induced on monuments by the action of specific pollutants are often systems of nonlinear, possibly degenerate, parabolic equations. Although some of the asymptotic properties of the solutions are known, one needs a numerical approximation scheme in order to have a quantitative forecast at any time of interest. In thi...

One of the common monuments in the Sassanid era was the square dome. Interestingly, corners and parts of the square dome were always geometrically proportionate to each other. Square domes have been mainly studied in terms of their historical background as well as the materials used. The present research, however, aimed to examine the geometric proportions governing the formation of square dome...
