Bifurcation Analysis of Endogenous Growth Models
It is important to recognize that bifurcation boundaries do not necessarily separate stable from unstable solution domains. Bifurcation boundaries can separate one kind of unstable dynamics domain from another kind of unstable dynamics domain, or one kind of stable dynamics domain from another …

Advances in numerical bifurcation software : MatCont
… of MatCont, a freely available toolbox, is bifurcation theory which is a field of hard analysis. Bifurcation theory treats dynamical systems from a high-level point of view. In the case of continuous dynamical systems this means that it considers nonlinear differential equations without any …

Slope and bifurcation on braided distributive fluvial systems
… through which channel networks on DFS evolve are bifurcation and avulsion. Instabilities in river channels that lead to bifurcation and avulsion are related to the 1) slope of the river channel, 2) the slope of the ground perpendicular to the channel, and 3) the ratio of the slope of the …

Structural-model experiments revealing bifurcation, instability and localization
… to analyze several aspects of instability and bifurcation occurring in structures and within materials. Photoelasticity is employed to analyze the localization of stress in ordered granular materials and near stiff and thin inclusions embedded in an elastic matrix. Prototypes have been designed …

BIFURCATION AND CHAOS OF NONLINEAR VIBRO-IMPACT SYSTEMS
… using the inversed mapping method. Neimark bifurcations in such a discrete system have also drawn a lot of interest to the author. The Neimark bifurcations in such a system have actually formed a boundary dividing the stable solution of positive and negative maps (inversed mapping). For the …

Equivariant Global Hopf Bifurcation in Abstract Nonlinear Parabolic Equations
… Thesis, we study local and global symmetric Hopf bifurcation in abstract parabolic systems by means of the twisted equivariant degree.

Convective Flow Patterns of a Three Generation Bifurcation Model
… experiment goes through three symmetrical 70¿¿ bifurcations before terminating at the model exits. The model not only demonstrated in-plane flow but was rotated to represent out-of-plane flow after each bifurcation. In the latter case the model was rotated 90¿¿ at each of the bifurcations, which …

Multilayered Structures under large Bending: Finite Solution and Bifurcation Analysis
… possible in-plane and out-of-plane incremental bifurcations. The analysis reveals that a multilayered structure can behave in a completely different way from the corresponding homogeneous plate. For a thick plate of neo-Hookean material for instance, the presence of a stiff coating strongly …

Robust bifurcation behavior in the presence of external random excitation
… of stability is examined within the context of bifurcation theory. Physically the problem is motivated by the flight dynamics of aircraft at large angles of attack and sideslip in a turbulent atmosphere. A qualitative criterion for robust bifurcation behavior is suggested and it is found the …

Application of Bifurcation Theory to Subsynchronous Resonance in Power Systems
A bifurcation analysis is used to investigate the complex dynamics of two heavily loaded single-machine-infinite-busbar power systems modeling the characteristics of the BOARDMAN generator with respect to the rest of the North-Western American Power System and the CHOLLA# generator with respect to …

On the stability of rotor bearing systems based on Hopf bifurcation theory
… effects are evaluated by applying the Hopf bifurcation theory (HBT) to the equations of motion. A method is developed for predicting the stability envelope of rotor-bearing systems using HBT. Results are compared with published literature obtained using a trial-and-error method. A method …
