Communication scheme by using synchronized chaotic systems
(IEEE, Piscataway, NJ, United States, 1996)A method to synchronize systems with chaotic behavior, in a masterslave configuration adapted to communication systems, is discussed. This work is motivated by the need for secure communication. In this method, the ... 
A gPCbased approach to uncertain transonic aerodynamics
(2010)The present paper focus on the stochastic response of a twodimensional transonic airfoil to parametric uncertainties. Both the freestream Mach number and the angle of attack are considered as random parameters and the ... 
Inductorless realisation of Chua oscillator
(IET, 1995)An inductorless realisation of a Chua oscillator, which exhibits chaotic behaviour is presented. This new realisation consists of the Wien bridge oscillator, coupled in parallel with the same nonlinear resistor used in the ... 
Model based anticontrol of chaos
(Institute of Electrical and Electronics Engineers Inc., 2003)We will consider model based anticontrol of chaotic systems. We consider both continuous and discrete time cases. We first assume that the systems to be controlled are linear and time invariant. Under controllability ... 
Model based anticontrol of discretetiime systems
(Institute of Electrical and Electronics Engineers, 2003)We will consider a modelbased approach for the anticontrol of some discretetime systems. We first assume the existence of a chaotic model in an appropriate form. Then by using an appropriate control input we try to match ... 
A modelbased scheme for anticontrol of some chaotic systems
(World Scientific Publishing, 2003)We consider a modelbased approach for the anticontrol of some continuous time systems. We assume the existence of a chaotic model in an appropriate form. By using a suitable input, we match the dynamics of the controlled ... 
A modelbased scheme for anticontrol of some discretetime chaotic systems
(World Scientific, 2004)We consider a modelbased approach for the anticontrol of some discretetime systems. We first assume the existence of a chaotic model in an appropriate form. Then by using an appropriate control input we try to match the ... 
Observer based chaotic message transmission
(World Scientific Publishing, 2003)We consider observer based synchronization of continuoustime chaotic systems. We present two message transmission schemes for such systems. The first one is based on chaotic masking and modulation, and the second one is ... 
On the control of chaotic systems in Lur'e form by using dither
(Institute of Electrical and Electronics Engineers, 199910)In this paper we propose the application of dither for controlling chaotic systems in the Lur'e form. Dither is a highfrequency periodic signal and has the effect of modifying the nonlinearity for some nonlinear systems. ... 
On the Hajek projection for truncated and censored data
(Scientific Publishers, 1993)Large sample properties of the productlimit estimators for truncated or censored data are usually achieved via the empirical cumulative hazard function estimators. Hajek projection of the empirical cumulative hazard ... 
Planewave dynamics of optical parametric oscillation with simultaneous sumfrequency generation
(Institute of Electrical and Electronics Engineers, 199906)This paper presents a theoretical analysis of sumfrequency generating optical parametric oscillators where a single nonlinear crystal is used for both parametric generation and sumfrequency generation. In these devices, ... 
Stability of delayed feedback controllers for discrete time systems
(Institute of Electrical and Electronics Engineers Inc., 2003)We consider the delayed feedback control (DFC) scheme for one dimensional discrete time systems. To analyze the stability, we construct a map whose fixed points correspond to the periodic orbits of the system to be controlled. ... 
A stability result for delayed feedback controllers
(Institute of Electrical and Electronics Engineers, 2003)We consider the delayed feedback control (DFC) scheme for one dimensional discrete time systems. To analyze the stability, we construct a map whose fixed points correspond to the periodic orbits of the system to be controlled. ... 
Stabilization of unstable periodic orbits for discrete time chaotic systems by using periodic feedback
(World Scientific Publishing, 2006)We propose a periodic feedback scheme for the stabilization of periodic orbits for discrete time chaotic systems. We first consider onedimensional discrete time systems and obtain some stability results. Then we extend ... 
Synchronization and chaotic masking scheme based on occasional coupling
(American Physical Society, 2000)Synchronization and a related message transmission scheme using synchronized chaotic systems was presented for discretetime systems. The scheme was based on occasional coupling of transmitter and receiver systems. The ...
