A Swarm Intelligence Based Coverage Hole Healing Approach for Wireless Sensor Networks [PDF]

open access: yesEAI Endorsed Transactions on Scalable Information Systems, 2020
In the WSN network, nodes are always deprived of battery and can’t be in operation for a long time. Some nodes may die sooner thanothers, creating a void in the area.

Chaotic Sensing [PDF]

open access: yesIEEE Transactions on Image Processing, 2018
We propose a sparse imaging methodology called Chaotic Sensing (ChaoS) that enables the use of limited yet deterministic linear measurements through fractal sampling. A novel fractal in the discrete Fourier transform is introduced that always results in the artefacts being turbulent in nature. These chaotic artefacts have characteristics that are image

Chaotic communications over radio channels [PDF]

open access: yes, 2001
The real issues of communicating over radio channels with continuous time chaotic signals are addressed. Synchronized and nonsynchronized methods are assessed.

Dynamic properties of the dynamical system SFnm(X), SFnm(f))

open access: yesApplied General Topology, 2020
Let X be a continuum and let n be a positive integer. We consider the hyperspaces Fn(X) and SFn(X). If m is an integer such that n > m ≥ 1, we consider the quotient space SFnm(X). For a given map f : X → X, we consider the induced maps Fn(f) : Fn(X) → Fn(

Chaotic itinerancy [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2003
Chaotic itinerancy is universal dynamics in high-dimensional dynamical systems, showing itinerant motion among varieties of low-dimensional ordered states through high-dimensional chaos. Discovery, basic features, characterization, examples, and significance of chaotic itinerancy are surveyed.

Digitization of chaotic signal for reliable communication in non-ideal channels [PDF]

open access: yes, 2008
A new method of chaotic communication system based on digitization of the chaotic signal is proposed. The digitally encoded chaotic signal is transmitted through a practical channel and recovered at the receiver.

A chaotic circuit based on Knowm memristor: modeling, analysis, and experimental verification

open access: yesShenzhen Daxue xuebao. Ligong ban, 2023
Previous research on memristors and their chaotic applications has mainly focused on the use of memristor emulators, with little research on constructing the chaotic circuit using real memristors.

The importance of choosing attractors for optimizing chaotic communications [PDF]

open access: yes, 2004
In this brief, we consider methods to improve the performance of chaotic communication schemes. We study a system using a receiver which explicitly includes the presence of noise in the channel.

ON EQUIVALENCE OF LINEAR CONTROL SYSTEMS AND ITS USAGE TO VERIFICATION OF THE ADEQUACY OF DIFFERENT MODELS FOR A REAL DYNAMIC PROCESS

open access: yesJournal of Optimization, Differential Equations and Their Applications, 2020
A problem of description of algebraic invariants for a linear control system that determine its structure is considered. With the help of these invariants, the equivalence problem of two linear time-invariant control systems with respect to actions of ...

IBGJO: Improved Binary Golden Jackal Optimization with Chaotic Tent Map and Cosine Similarity for Feature Selection

open access: yesEntropy, 2023
Feature selection is a crucial process in machine learning and data mining that identifies the most pertinent and valuable features in a dataset. It enhances the efficacy and precision of predictive models by efficiently reducing the number of features ...
