Discrete-time synchronization of chaotic systems for secure communication [PDF]

open access: yes, 2012
This paper deals with the problem of designing an exact nonlinear reconstructor for discrete-time chaotic encrypted messages. More precisely, we investigate the problem of designing a discrete-time dead-beat observer for nonlinear systems with unknown ...

Nonlinear dynamics of a rotating shaft with a breathing crack [PDF]

open access: yes, 2011
In this paper, the effects of a breathing crack on the vibratory characteris- tics of a rotating shaft are investigated. A new, simple and robust model composed of two rigid bars connected with a nonlinear flexural spring is proposed.

Forecasting high waters at Venice Lagoon using chaotic time series analisys and nonlinear neural netwoks [PDF]

open access: yes, 2000
Time series analysis using nonlinear dynamics systems theory and multilayer neural networks models have been applied to the time sequence of water level data recorded every hour at 'Punta della Salute' from Venice Lagoon during the years 1980-1994.

Study on the chaotic dynamics in yaw-pitch-roll coupling of asymmetric rolling projectiles with nonlinear aerodynamics

open access: yes, 2019
To predict the coning motion forms of a rolling projectile with configurational asymmetries, the nonlinear characteristics for the system are investigated in this paper.

Chaotic rotation of a towed elliptical cylinder

open access: yes, 2014
In this paper I consider the self-excited rotation of an elliptical cylinder towed in a viscous fluid as a canonical model of nonlinear fluid–structure interactions with possible applications in the design of sensors and energy extraction devices. First,

Measurement of small signal variations using one-dimensional chaotic maps [PDF]

open access: yes
A novel electronic signal Measurement System (MS) based on one-dimensional chaotic maps (Logistic Map (LM) and Tent Map (TM)) has been developed, analysed and tested.

Essays on the nonlinear and nonstochastic nature of stock market data [PDF]

open access: yes, 2002
The nature and structure of stock-market price dynamics is an area of ongoing and rigourous scientific debate. For almost three decades, most emphasis has been given on upholding the concepts of Market Efficiency and rational investment behaviour.

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.
