Symmetry-breaking in a rate model for a biped locomotion central pattern generator [PDF]
, 2014 The timing patterns of animal gaits are produced by a network of spinal neurons called a Central Pattern Generator (CPG). Pinto and Golubitsky studied a four-node CPG for biped dynamics in which each leg is associated with one flexor node and one ...

Generalized Hopf bifurcation in coupled excitable systems [PDF]
, 2018 Bifurcations of equilibria of two coupled FitzHugh-Nagumo excitable systems are analyzed. It is shown that there are domains for values of coupling and excitability parameters for all three types of Hopf bifurcation.

Hopf bifurcation analysis of Sel’kov model with time delay
Xi'an Gongcheng Daxue xuebao, 2023 The Sel’kov model with time-delay diffusion under homogeneous Neumann boundary conditions is considered. Firstly, the local asymptotically stability of the positive equilibrium point of the model is obtained by using spectral theory.

Demulsifying agent simplified model for offshore oil wells
The Canadian Journal of Chemical Engineering, EarlyView.Abstract This article addresses key challenges in offshore petroleum production caused by multiphase flow instabilities, such as slug flow and emulsion formation. Traditionally, severe slugging is mitigated by increasing wellhead backpressure through partial choke valve closure. In this context, a simplified dynamic model—the fast offshore wells model (

Subcritical Hopf bifurcations in a car-following model with reaction-time delay [PDF]
, 2005 A nonlinear car-following model of highway traffic is considered, which includes the reaction-time delay of drivers. Linear stability analysis shows that the uniform flow equilibrium of the system loses its stability via Hopf bifurcations and thus ...
