Preliminary design of a test rig for combining passive nonlinear isolation with active control

, 2012
Resilient elements are typically used to isolate delicate equipment from a vibrating host structure. Conventionally, these isolators are designed to operate in their linear region, but more recently nonlinear isolators have been employed to increase the ...

Investigation of Upper Critical Magnetic Field in Two‐Band Model for the Iron‐Based Superconductors Ca0.83La0.17FeAs2 and Ca0.8La0.2Fe0.98Co0.02As2

Advanced Physics Research, EarlyView.
A two‐band Ginzburg–Landau model was applied to investigate the superconducting properties of and. Analytical expressions for critical magnetic fields, coherence length, penetration depth, and anisotropic were derived, showing strong agreement with experimental observations and effectively describing anisotropic multi‐band superconductivity.

Harmonic Solution of Higher-Dimensional Second Order Kuramoto Oscillator Network

IEEE Access
Obtaining the solution of Kuramoto oscillator model is an effective way to understand the mechanism behind the dynamical behaviors it represents. However, it is not an easy work to get, even the approximation solution for the second order Kuramoto ...

Green-pumped, picosecond MgO:PPLN optical parametric oscillator

, 2011
We investigate the performance of a magnesium-oxide-doped periodically poled lithium niobate crystal (MgO:PPLN) in an optical parametric oscillator (OPO) synchronously-pumped by 530nm, 20ps, 230MHz pulses with an average power of up to 2W from a ...
