Sensitivity enhancement of nonlinear micromechanical sensors using parametric symmetry breaking

Microsystems & Nanoengineering
The working mechanism of resonant sensors is based on tracking the frequency shift in the linear vibration range. Contrary to the conventional paradigm, in this paper, we show that by tracking the dramatic frequency shift of the saddle-node bifurcation ...

Bifurcations of a modified Leslie–Gower predator–prey model with fear, Allee effect and hunting cooperation strategy

Journal of Biological Dynamics
The fear preoften leads to changes in the physiological characteristics of the prey. Different stages of prey exhibit different physiological behaviours, such as susceptibility to predator risk, which often leads to Allee effect.

Multiple bifurcations of a Leslie-type predator-prey model with additional food in predators

Xi'an Gongcheng Daxue xuebao
To investigate the impact of additional food for predators, a Leslie-Gower type predator-prey model with a Holling type Ⅲ functional response is established, assuming that the predator has multiple food sources.By applying the fundamental theorem of ...

Bifurcation analysis of surge and rotating stall in the Moore-Greitzer compression system [PDF]

, 2002
A simple compression system model, described by a set of three ordinary nonlinear differential equations (the Moore-Greitzer model) is studied using bifurcation analysis to give a qualitative understanding of the presence of surge and rotating stall ...

Control-based continuation for investigating nonlinear experiments [PDF]

, 2010
This paper presents a systematic experimental study of two one-degree-of-freedom nonlinear devices using the newly introduced control-based continuation method by Sieber and Krauskopf [Nonlinear Dynamics 2008].

Sil'nikov-saddle-node interaction near a codimension-2 bifurcation: Laser with injected signal

, 1997
We describe a Sil'nikov-saddle-node interaction in the proximity of a Hopf-saddle-node bifurcation both from numerical and theoretical viewpoints, inspired by numerical observations on a three-dimensional model of a laser with injected signal.

Saddle-node bifurcation control of macroscopic traffic flow model considering vehicle braking effect

Traffic congestion is usually caused by many factors. When the traffic system passes through some critical bifurcation points, the stability state of the system will change abruptly, resulting in the loss of traffic stability. The saddle-node bifurcation

A Subtle Link in Switched Dynamical Systems: Saddle-Node Bifurcation Meets Border Collision

, 2008
— Switched dynamical systems are known to exhibit border collision, in which a particular operation is terminated and a new operation is assumed as one or more parameters are varied. In this paper, we report a subtle relation between border collision and
