Construction of chaotic dynamical system

open access: yesMathematical Modelling and Analysis, 2010
The first‐order difference equation xn+ 1 = f(xn ), n = 0,1,…, where f: R → R, is referred as an one‐dimensional discrete dynamical system. If function f is a chaotic mapping, then we talk about chaotic dynamical system.

Bilinear dynamical systems [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2005
In this paper, we propose the use of bilinear dynamical systems (BDS)s for model-based deconvolution of fMRI time-series. The importance of this work lies in being able to deconvolve haemodynamic time-series, in an informed way, to disclose the underlying neuronal activity.

Holographic memory updated by contradictory information: influence of low frequency attenuation on response stability

open access: yesКомпьютерная оптика, 2020
A 6f-scheme of Fourier holography with resonant architecture is considered, which implements memory replenishment with new information that contradicts the previously recorded. It is shown that the low-frequency attenuation due to the nonlinearity of the

Oscillation thresholds via the novel MBR method with application to oncolytic virotherapy

open access: yesNonlinear Analysis, 2022
Oncolytic virotherapy is a therapy for the treatment of malignant tumours. In some undesirable cases, the injection of viral particles can lead to stationary oscillations, thus preventing the full destruction of the tumour mass.

Dynamical versus diffraction spectrum for structures with finite local complexity [PDF]

open access: yes, 2014
It is well-known that the dynamical spectrum of an ergodic measure dynamical system is related to the diffraction measure of a typical element of the system.

Resolvent-Generated Generalized Spectral Operators for Nonlinear Dynamical Systems via Koopman Semigroups

open access: yesMathematics
Spectral methods form a cornerstone of linear dynamics, where evolution is resolved into harmonic modes governed by eigenvalues and spectral measures of normal operators.

Planar Bistable Structures Detection via the Conley Index and Applications to Biological Systems

open access: yesMathematics, 2023
Bistability is a ubiquitous phenomenon in life sciences. In this paper, two kinds of bistable structures in two-dimensional dynamical systems are studied: one is two one-point attractors, another is a one-point attractor accompanied by a cycle attractor.

Improving Transient Performance of Adaptive Control Architectures using Frequency-Limited System Error Dynamics

open access: yes, 2013
We develop an adaptive control architecture to achieve stabilization and command following of uncertain dynamical systems with improved transient performance. Our framework consists of a new reference system and an adaptive controller.

Dynamic system classifier [PDF]

open access: yesPhysical Review E, 2016
Stochastic differential equations describe well many physical, biological and sociological systems, despite the simplification often made in their derivation. Here the usage of simple stochastic differential equations to characterize and classify complex dynamical systems is proposed within a Bayesian framework. To this end, we develop a dynamic system
