Arnol′d tongues arising from a grazing-sliding bifurcation

open access: yes, 2009
The Neımark–Sacker bifurcation, or Hopf bifurcation for maps, is a well-known bifurcation for smooth dynamical systems. At this bifurcation a periodic orbit loses stability, and, except at certain “strong” resonances, an invariant torus is born.

Process design in SISO systems with input multiplicity using bifurcation analysis and optimisation [PDF]

open access: yes, 2010
This paper presents an approach using continuation and optimisation methods for modifying a process design to avoid control difficulties caused by input multiplicity.

Equilibrium Point Bifurcation and Singularity Analysis of HH Model with Constraint

open access: yesAbstract and Applied Analysis, 2014
We present the equilibrium point bifurcation and singularity analysis of HH model with constraints. We investigate the effect of constraints and parameters on the type of equilibrium point bifurcation.

Multi-parameter uncertainty analysis of a bifurcation point [PDF]

open access: yesNonlinear Processes in Geophysics, 2006
Parameter uncertainty analysis of climate models has become a standard approach for model validation and testing their sensitivity. Here we present a novel approach that allows one to estimate the robustness of a bifurcation point in a multi-parameter ...

FUNDAMENTAL MODELS OF STRUCTURAL STABILITY

open access: yesRudarsko-geološko-naftni Zbornik, 2017
In this paper, basic structural stability phenomena are described. After some general comments about stability in the field of civil engineering, four elementary sources of nonlinearity are mentioned: of equilibrium equations, strain (geometry) relations,

Dynamic Behaviors of a Two-Degree-of-Freedom Impact Oscillator with Two-Sided Constraints

open access: yesShock and Vibration, 2021
The dynamic model of a vibroimpact system subjected to harmonic excitation with symmetric elastic constraints is investigated with analytical and numerical methods.

The classification of bifurcations with hidden symmetries [PDF]

open access: yes, 2000
We set up a singularity-theoretic framework for classifying one-parameter steady-state bifurcations with hidden symmetries. This framework also permits a non-trivial linearization at the bifurcation point.

Investigation of Early Warning Indexes in a Three-Dimensional Chaotic System with Zero Eigenvalues

open access: yesEntropy, 2020
A rare three-dimensional chaotic system with all eigenvalues equal to zero is proposed, and its dynamical properties are investigated. The chaotic system has one equilibrium point at the origin.

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.
