An anisotropic, inhomogeneous cosmological model is proposed in which the inhomogeneity is generated by shear fluctuations. This is a sufficient condition for dissipative heating by collisional neutrinos to explain the present large heat content of the universe, S(b o) approximately 10(8), together with its isotropy and comparative homogeneity on large

Chaotic Continua in Chaotic Dynamical Systems
2021In this article, for any graph G we define a new notion of “free tracing property by free G-chains” on G-like continua and we show that a positive topological entropy homeomorphism f of a G-like continuum X admits a Cantor set Z in X such that any sequence \((z_1,z_2,...,z_n)\) of points in Z is an IE-tuple of f, Z has the free tracing property by free

Chaotic simulated annealing with decaying chaotic noise
IEEE Transactions on Neural Networks, 2002By adding chaotic noise to each neuron of the discrete-time continuous-output Hopfield neural network (HNN) and gradually reducing the noise, a chaotic neural network is proposed so that it is initially chaotic but eventually convergent, and, thus, has richer and more flexible dynamics compared to the HNN.

AbstractA method to transfer secret information using chaotic dynamical systems is proposed. It is based on modulating a chaotic system with the message such that its time evolution contains the hidden information. Decryption of the cipher is achieved by chaos control. Operation of the scheme is demonstrated by en‐ and decoding a short german text.

Chaotic Footloose Capital. [PDF]
Nonlinear dynamics, psychology, and life sciences, 2005 This paper examines the long-term behavior of a discrete-time Footloose Capital model, where capitalists, who are themselves immobile between regions, move their physical capital between regions in response to economic incentives. The spatial location of industry can exhibit cycles of any periodicity or behave chaotically.

Summary: The resonance problem and chaotic dynamics, described by the Duffing equation, are reexamined when excitation is external or parametric. Starting from the similarity existing between these two different phenomena, a new concept is introduced: \textit{chaotic resonance}.
