Amoeba proteus, Amoeba dubia, and Chaos chaos all contain similar plate-like and bipyramidal cytoplasmic crystals. Isolated crystals, purified by recrystallization from water, yield plate-like crystals which have been shown to be identical with synthesized carbonyl diurea (triuret) with regard to physicochemical properties, elemental analysis, x-ray diffraction patterns, infrared spectra, and o...

in this research prediction methods of artificial neural network and chaos theory are employed to predict daily, weekly and monthly runoff. for this, runoff series data observed at pole-kohneh located in the qareh-soo river. the nonlinear predictions of chaos are found to be in close agreement with the observed runoff, with high correlation coefficient for daily and weekly time scales. predicte...

Delvenne, Kůrka and Blondel have defined new notions of computational complexity for arbitrary symbolic systems, and shown examples of effective systems that are computationally universal in this sense. The notion is defined in terms of the trace function of the system, and aims to capture its dynamics. We present a Devaney-chaotic reversible cellular automaton that is universal in their sense,...

Certain symmetry properties of Hamiltonian systems possessing hyperbolic fixed points with homoclinic and heteroclinic saddle connections are exploited to conclude chaotic dynamics are present under time periodic perturbations. Specifically, the theorems are applied to a set of exact solutions to the semi-geostrophic equations in an elliptical elliptical tank. Introduction We start this paper o...

We study the properties of homogeneous and isotropic turbulence in higher spatial dimensions through lens chaos predictability using numerical simulations. employ both direct simulations (DNS) calculations Eddy Damped Quasi Normal Markovian (EDQNM) closure approximation. Our results show a remarkable transition to non-chaotic regime above critical dimension $d_c\approx 5.88$. relate these energ...

In this paper new and existing approaches are developed to compute the bit error rate for chaos-based communication systems. The multi-user coherent antipodal chaos shift keying system is studied and evaluated in its coherent form, in the sense of perfect synchronization between transmitted and received chaotic sequences. Transmission is through an additive white Gaussian noise channel. Four me...

In this paper, a novel formulation of discrete chaotic iterations in the field of dynamical systems is given. Their topological properties are studied: it is mathematically proved that, under some conditions, these iterations have a chaotic behavior in the meaning of Devaney. This chaotic behavior allows us to propose a way to generate new hash functions. An illustration example is detailed in ...
