A new two-dimensional cellular automata and finite difference (CA-FD) model of dendritic growth was improved. which a perturbation function was introduced to control the growth of secondary and tertiary dendrite. the concentration of the solute was clearly defined as the liquid solute concentration and the solid-phase solute concentration in dendrite growth processes. and the eight mo... https://olivebookmarks.com/story19598698/red%C3%A9finition-des-r%C3%A9cits-urbains-analyse-de-deux-d%C3%A9placements-du-centre-politique-de-macap%C3%A1-1944-et-1967
