Abrupt Change Detection Method Based on Features of Lorenz Trajectories
Atmosphere, 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 ...

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

Modeling the dynamic semantics of a computer program
Цифровые 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 ...

Construction of chaotic dynamical system
Mathematical 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.

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

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

ON PERIODIC DYNAMICAL SYSTEMS [PDF]
Chinese Annals of Mathematics, 2004 In this paper, we investigate the existence and the global stability of periodic solution for dynamical systems with periodic interconnections, inputs and self-inhibitions. The model is very general, the conditions are quite weak and the results obtained are universal.
