6. The effects of Gaussian size distribution dust particles in a complex plasma

Author

Subjects
*GAUSSIAN distribution, *DUSTY plasmas, *PARTICLES, *DISTRIBUTION (Probability theory)
Abstract

Abstract: Investigations for a dusty plasma with many different dust grain species are adopted, which varies self-consistently with the system parameters. Two cases have been studied. One is that the dust size distribution is given by Gaussian distribution. The other is that there is only one kind of dust grains (mono-sized dusty plasma) whose size is the average one of Gaussian distribution. The comparisons between them have been made and it is found that the linear phase velocity is different. [Copyright &y& Elsevier]

7. Controlling hyperchaos in the new hyperchaotic system

Author

Dou, Fu-quan, Sun, Jian-an, Duan, Wen-shan, and Lü, Ke-pu

Subjects
*CHAOS theory, *CONTROL theory (Engineering), *FEEDBACK control systems, *PERIODIC functions, *WOLFRAM language (Computer program language)
Abstract

Abstract: The control problem of a new hyperchaotic system is investigated. The linear, speed, nonlinear doubly-periodic function feedback controls are used to suppress hyperchaos to unstable equilibrium. Limit cases of doubly-periodic function are considered and the hyperbolic function and trigonometric function feedback control laws are derived. The Routh–Hurwitz criterion is applied to study the conditions of the asymptotic stability of the controlled hyperchaotic system. Based on Mathematica program, numerical simulations are presented to demonstrate the effectiveness of the proposed controllers. [Copyright &y& Elsevier]
