Abrupt Change Detection Method Based on Features of Lorenz Trajectories

open access: yesAtmosphere, 2021
This paper presents a definition of bifurcation-type abrupt changes based on the bifurcation features of Lorenz trajectories. These abrupt changes are the result of the transition behavior of dynamical system trajectories among different equilibrium ...

On the Dynamics of Systems of Urns [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2015
In this paper we present an analysis of some generalization of the classic urn and balls model. In our model each urn has a fixed capacity and initially is filled with white balls. Black balls are added to the system of connected urns and gradually displace white balls.

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.

Isola in a linear one‐degree‐of‐freedom feedback system with actuator rate saturation

open access: yesInternational Journal of Mechanical System Dynamics, 2023
This short communication uses numerical continuation to highlight the existence of an isola in a simple one‐degree‐of‐freedom harmonically forced feedback system with actuator rate limiting as its only nonlinear element.

Modeling the dynamic semantics of a computer program

open access: yesЦифровые модели и решения, 2023
In this paper, two approaches are used to construct the dynamic semantics of computer programs: the first is the representation of mathematical models of computational processes generated by a computer program in the form of a discrete transformer; the ...

A Dynamic Biometric Authentication Algorithm for Near-Infrared Palm Vascular Patterns

open access: yesIEEE Access, 2020
In this paper we apply a novel approach to near-infrared subcutaneous palm vascular pattern authentication. The proposed method relies on a recursive algorithm based on a positive linear dynamical system whose evolution depends on the two matrices ...

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.

Dynamic Reasoning Systems [PDF]

open access: yesACM Transactions on Computational Logic, 2015
A dynamic reasoning system (DRS) is an adaptation of a conventional formal logical system that explicitly portrays reasoning as a temporal activity, with each extralogical input to the system and each inference rule application being viewed as occurring at a distinct timestep.

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
