TL;DR: A circuit that is useful for studying applications of synchronized chaotic systems is presented and some of the considerations that went into designing this circuit are discussed.
Abstract: Recent work on the synchronizing of chaotic systems raises the possibility of finding ways to apply chaos to real problems. Studying these applications requires that real physical systems be used, as well as mathematical models. There are no general rules for designing or building such physical systems. We present here a circuit that is useful for studying applications of synchronized chaotic systems and discuss some of the considerations that went into designing this circuit. We also show how this circuit is used for studying cascaded synchronized chaotic systems.

TL;DR: The topics discussed are new driving signals, the stability of chaotically driven systems, synchronization of chaotic systems, and applications to signal processing.
Abstract: Recent work using chaotic signals to drive nonlinear systems shows that chaotic dynamics is rich in new application possibilities. Among these are stable system design and synchronization. The topics discussed are new driving signals, the stability of chaotically driven systems, synchronization of chaotically driven systems, and applications to signal processing. >

TL;DR: The approach of using nonlinear dynamics concepts to guide synthesis of new nonlinear systems leads to the concepts of synchronization of chaotic systems and pseudoperiodic driving.
Abstract: Recent work using chaotic signals to drive nonlinear systems shows that chaotic dynamics is rich in new application possibilities. The approach of using nonlinear dynamics concepts to guide synthesis of new nonlinear systems leads to the concepts of synchronization of chaotic systems and pseudoperiodic driving. These are only the beginnings of new and unique uses of chaotic dynamics.© (1992) COPYRIGHT SPIE--The International Society for Optical Engineering.

TL;DR: In this paper, experimental data was presented for ferromagnetic resonance in an yttrium iron garnet sphere slightly below the threshold field for saturation, and it was found that significantly different behavior occurs depending on whether the dc field is aligned with the [111, [100], or [110] axes of the crystal.
Abstract: Experimental data is presented for ferromagnetic resonance in an yttrium iron garnet sphere slightly below the threshold field for saturation. It is found that significantly different behavior occurs depending on whether the dc field is aligned with the [111], [100], or [110] axes of the crystal. Explanations are proposed to account for the observed behavior, which in the [100] and [110] cases involve the formation of macroscopic magnetization patterns. These two cases also exhibit frequency reversal below threshold, in which the frequency is observed to increase as the field is decreased.
