Figure 12. The evolution of spiral wave under different additive Gaussian white noise.
Blocked area is within 90≤i ≤95, 1≤j ≤100, x k = 0.3. The area forced by external currents with diversity is within the area 90≤i≤95, 90≤j ≤95, I 0 = 60, I 1 = 40, for noise intensity Dnoise = 100 (panel a) ; Dnoise = 200 (panel b) ; Dnoise = 300 (panel c) ; Dnoise = 500 (panel d), coupling intensity D = 2, transient period t = 800 and no-flux boundary condition is used.
