Chaos Communication Using Chaos

We propose several new detector schemes for non-coherent communication with a chaotic signal. To successfully decode the signal the detector needs to know only the chip timing and form of the dynamical system utilised by the encoder. We show that this method can be used to achieve bit error rates comparable to other non-coherent schemes. Moreover, our method also benefits from additional genera...

Chaos/Complexity Theory and Education

Sciences exist to demonstrate the fundamental order underlying nature. Chaos/complexity theory is a novel and amazing field of scientific inquiry. Notions of our everyday experiences are somehow in connection to the laws of nature through chaos/complexity theory’s concerns with the relationships between simplicity and complexity, between orderliness and randomness (Retrieved from http://www.inc...

Column Profiles for Membrane Column Sections

A novel graphical method of analysing continuous membrane separation systems has been developed. The method is applicable to all counterand co-current membrane modules – single-stage, cascades, and membrane columns. All configurations can be broken down into “column sections”, no matter how complex the arrangement. Each column section, which resembles a typical single-stage separator, is modell...

Chaos and Quantum Chaos in Cosmological Models

Spatially homogeneous cosmological models reduce to Hamiltonian systems in a low dimensional Minkowskian space moving on the total energy shellH = 0. Close to the initial singularity some models (those of Bianchi type VIII and IX) can be reduced further, in a certain approximation, to a non-compact triangular billiard on a 2-dimensional space of constant negative curvature with a separately con...
