General Construction Method and Proof for a Class of Quadratic Chaotic Mappings

open access: yesMathematics
The importance of chaotic systems as the main pseudo-random cryptographic generator of encryption algorithms in the field of communication secrecy cannot be overstated, but in practical applications, researchers often choose to build upon traditional ...

Two-parameter locus of boundary crisis: mind the gaps!

open access: yes, 2010
Boundary crisis is a mechanism for destroying a chaotic attractor when one parameter is varied. In a two-parameter setting the locus of boundary crisis is associated with curves of homo- or heteroclinic tangency bifurcations of saddle periodic orbits. It

Chaotic Oscillations of Nonideal Plane Pendulum Systems [PDF]

open access: yes, 2012
The atlas of maps of dynamic regimes of system ”pendulum–electric motor” is constructed. It is established that the deterministic chaos is a typical steady-state regime of the given system. Its class of Feigenbaum universality is defined.

Technology Transfer to Underwater Archaeology: The LAHKE Project at the Submerged Neolithic Site of La Marmotta

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT This document is a report on the field application of non‐invasive geophysical and robotic prospecting methods at the submerged Neolithic site of La Marmotta (Lake Bracciano, Italy), within the LAHKE (LAke Heritage Knowledge and Exploration) project; the study focuses on the practical validation, adaptation and transfer of existing ...

Approximation of invariant measures for a class of maps with indifferent fixed points

open access: yes, 2005
Certain dynamical systems on the interval with neutrally stable repelling points admit invariant probability measures which are absolutely continuous with respect to Lebesgue measure.

Rapid fluctuations of chaotic maps on RN

open access: yes, 2006
The iterates fn of a chaotic map f display heightened oscillations (or fluctuations) as n→∞. If f is a chaotic interval map in one dimension, then it is now known that the total variation of fn on that interval grows exponentially with respect to n [G ...

Prescribing competence: The pros and cons of different methods for assessment

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Evaluating a medical graduate’s competence in rational prescribing is challenging. With the aim to guide and inspire teachers, this narrative review explores different methods that can be used to assess prescribing competence. Each method has its own advantages and disadvantages, and thus a mix of different assessment methods is needed throughout the ...

A New Keyed Hash Function Based on Compounded Chaotic Maps

open access: yesIEEE Access
In this paper, we firstly construct a new chaotic map by compounding a couple of chaotic maps and, using specific mathematical tools (i.e., Lyapunov exponent), we prove its sensitivity to the initial conditions and the underlying chaotic behavior ...
