BER Performance Improvement of Dual Chaotic Maps Based on STBC Communication System

open access: yesAl-Khawarizmi Engineering Journal, 2022
Sensitive information of any multimedia must be encrypted before transmission. The dual chaotic algorithm is a good option to encrypt sensitive information by using different parameters and different initial conditions for two chaotic maps.

Chaotic maps in hyperspaces

open access: yesReal Analysis Exchange, 1995
Suppose \(X\) to be a compact metric space, \(w_1, w_2, \dots , w_m\) invertible contractive selfmaps. The iterated function system \((X;w_1,w_2,\dots ,w_m)\) satisfies the open set condition, if \(X\) is an attractor of the system \((X,w_1,w_2,\dots ,w_m)\) and there is a nonvoid open \(O\subseteq X\) such that \(w_i[O]\cap w_j[O]=\emptyset\) for \(i ...

From Determinism and Probability to Chaos: Chaotic Evolution towards Philosophy and Methodology of Chaotic Optimization

open access: yesThe Scientific World Journal, 2015
We present and discuss philosophy and methodology of chaotic evolution that is theoretically supported by chaos theory. We introduce four chaotic systems, that is, logistic map, tent map, Gaussian map, and Hénon map, in a well-designed chaotic evolution ...

Deep Learning Pose Estimation for Phenotyping of Co‐Occurring Hyperkinetic Movement Disorders

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To explore whether routine outpatient video combined with deep learning‐based pose estimation and clinically interpretable kinematic features can support multi‐label phenotyping of co‐occurring hyperkinetic movement disorders (HMDs).

Model‐Guided Design of Paper Membrane Architectures for Controlled Flow and Enhanced Diagnostic Sensitivity

open access: yesAdvanced Engineering Materials, EarlyView.
Geometrical modifications on nitrocellulose membranes can result in observable differences in signal intensity relative to a reference membrane (top and bottom left). Using two reference experiments, we have developed a theoretical model that can reproduce the experimentally observed flow changes and provide information on membrane parameters, e.g ...

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 ...

ESTIMATING HYPERBOLICITY OF CHAOTIC BIDIMENSIONAL MAPS [PDF]

open access: yesInternational Journal of Bifurcation and Chaos, 2012
We apply to bidimensional chaotic maps the numerical method proposed by Ginelli et al. [2007] to approximate the associated Oseledets splitting, i.e. the set of linear subspaces spanned by the so-called covariant Lyapunov vectors (CLV) and corresponding to the Lyapunov spectrum.

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

open access: yesAdvanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.
