The essential phenomena of chaotic systems are reviewed with several references to biological applications. Difference and differential equations are discussed separately, followed by a shorter chapter on measures, dimensions, and entropy. Several well-known model systems (like the logistic map, the Baker's transformation, or the horseshoe map for ...

Chaos: An Interdisciplinary Journal of Nonlinear Science, 1992
The spectra of quantized chaotic billiards from the point of view of scattering theory are discussed. It is shown how the spectral and resonance density functions both fluctuate about a common mean. A semiclassical treatment explains this in terms of classical scattering trajectories and periodic orbits of the Poincaré scattering map.

In this paper, chaos is applied to the control of moving robots in order to generate random-like trajectories needed in tasks such as exploration, scanning natural terrains or mapping of unknown environments. Synchronization between the robots of a team is achieved by exploiting the paradigm of mirror neurons, i.e. a neural structure playing a key role

Chaotic Politics, Chaotic Relationships
2013Political conflicts have great potentiality for social conflicts in society. Reviewing history shows that political collisions have affected significantly the relationships between nations. Ian McEwan’s contemporary fiction is in fact demonstration of conflicts in the twentieth century, and this papers aims to introduce a novel picture of politics ...

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.

We consider the problem of stabilizing unstable equilibria by discrete controls (the controls take discrete values at discrete moments of time). We prove that discrete control typically creates a chaotic attractor in the vicinity of an equilibrium.

Abstract A distinctive, sustained atrial arrhythmia, characterized by chaotic and random atrial activity with at least three different types of “P” waves in a single electrocardiographic lead and variability of the P-P, R-R, and P-R intervals, has been described in 31 patients. This disturbance has been named chaotic atrial mechanism (CAM).

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.

We examine the dynamical roles of nonattracting chaotic sets known as chaotic saddles in an Alfvén wave system described by the driven-dissipative derivative nonlinear Schrödinger equation. These Alfvén chaotic saddles have gaps which are filled at the onset of chaos via a saddle-node bifurcation and at a chaotic transition via an interior crisis.
