order4dwhere x, y, z and w are the stateful variables of chaotic system, q(0 q ≤ 1) is the order of fractional-order differential equation, where W(w) is defined as W(w) = a + 3bw 2, and a, b, α, β, γ, and ρ are the system parameters.. InThe home of 4D Number Plates. We are proud to have pioneered the 4D number plate concept and even prouder to be leading from the front. With over 10 years of experience in
