Bifurcation of solutions from infinity for certain nonlinear eigenvalue problems of fourth-order ordinary differential equations

Electronic Journal of Differential Equations, 2018
In this article, we study the global bifurcation from infinity of nonlinear eigenvalue problems for ordinary differential equations of fourth order. We prove the existence of unbounded continua of solutions emanating from asymptotically bifurcation ...

Bifurcation Analysis and Rare Attractors in Parametrically Excited Pendulum Systems

An application of the new method of complete bifurcation groups (MCBG) in a parametrically excited pendulum system with additional linear restoring moment and with the periodically vibrating point of suspension in both directions is introduced ...

Stability and Bifurcation Bahaviour of Electrostatic Torsional NEMS Varactor Influenced by Dispersion Forces

, 2007
The influences of Casimir and van der Waals forces on the nano-electromechanical systems (NEMS) electrostatic torsional varactor are studied. A one degree of freedom, the torsional angle, is adopted, and the bifurcation behaviour of the NEMS torsional ...

Material‐Driven Neuronal Oscillators and Filters via Active Reactance in CC‐NDR and VC‐NDR Electro‐Thermal Memristors

Advanced Physics Research, EarlyView.
Active reactance in electro‐thermal memristors emerges intrinsically from rapid thermal switching of device resistance, linking current‐controlled and voltage‐controlled negative differential resistance to neuronal spiking dynamics. Opposing temperature coefficients of resistance give rise to active inductive or capacitive responses, enabling tunable ...

Impedance Spectroscopy of Bifurcation Oscillations in S‐Type Self‐Oscillatory Devices

Advanced Physics Research, EarlyView.
Impedance spectroscopy (IS) reveals stability regimes and bifurcation dynamics in S‐type self‐oscillatory devices. By linking nonlinear control theory with frequency‐domain measurements, experimental signatures of oscillations, entrainment, and phase locking are directly identified.

Methodology of scenario planning for post-war reconstruction of Ukraine

European Journal of Management Issues
The process of post-war reconstruction of Ukraine should be based on international cooperation and funding, similar to the Marshall Plan for the reconstruction of Germany and Europe after World War II. The unstable conditions of the project's financial,
