Polymer Crystallization:
Nucleation & Growth processes with automata
Automaton: a machine that is activated by a concealed
mechanism and power source within itself.
Nucleation:
Random in space and time
Depending on temperature
Nucleability
of the material
Growth and Perfection:
Uniform in all space directions
Independing on temperature
White intensity shows perfection
Time scales:
Tw, Global-Waiting-Time:
  time elapsed between two succesive nucleations
Tg, Growth-Time:
time it takes to grow "one unit" of growth
Tw ~ Tg:
High nucleability: many small molecules.
Tw >> Tg:
Low nucleability: small number of great molecules
1. With uniform temperature field:
1.1 Tw ~ Tg
Final tesselation
1.2 Tw >> Tg
Final tesselation
2. With non-uniform temperature field:
2.1 Left cooling
Final tesselation
2.2 Border cooling
Final tesselation
