(a) The dependence of on ε with N = 4096, and 8192 for V_n chosen randomly from the interval (0.7, 1.3) and with N = 2048, and 4096 for V_n chosen randomly from the interval (0.3, 1.7). For all cases, the lowest 10% of frequency modes are initially excited and the nonlinear parameter α = 1.0. (b) The dependence of on α with N = 4096, and 8192 for V_n chosen randomly from the interval (0.7, 1.3) and with N = 2048, and 4096 for V_n chosen randomly from the interval (0.3, 1.7). For all cases, the lowest 10% of frequency modes are initially excited and the energy density ε = 0.015.
