Applied Sciences, 2022 Mechanical resonance occurs during the operation of a maglev inertially stabilized platform (MISP). The MISP is driven by the motor gear and the gear clearance changes during commutation, which makes the resonance frequency variable.

Resonance suppression from color reconnection [PDF]
Physical Review D, 2018 We present studies that show how multi-parton interaction and color reconnection affect the hadro-chemistry in proton-proton (pp) collisions with special focus on the production of resonances using the PYTHIA8 event generator. We find that color reconnection suppresses the relative production of meson resonances such as $\rho_{0}$ and K*, providing an ...

Numerical Study of Forced Vibration Suppression by Parametric Anti-Resonance
Archives of Acoustics, 2016 The parametric anti-resonance phenomenon as an active damping tool for suppression of externally excited resonant vibration is numerically studied herein. It is well known fact that the anti-resonance phenomenon, i.e.

Research on Adaptive Suppression of LCL Converter Resonance Grid-Connected System
Journal of Electrical and Computer Engineering, 2020 LCL-type converters are widely used in grid-connected systems due to their small size and good filtering performance. However, the resonance suppression problem brought by the LCL filter cannot be ignored.

Selective resonance suppression 1H‐[13C] NMR spectroscopy with asymmetric adiabatic RF pulses [PDF]
, 2009 Despite obvious improvements in spectral resolution at high magnetic field, the detection of C-13 labeling by H-1-[C-13] NMR spectroscopy remains hampered by spectral overlap, such as in the spectral region of H-1 resonances bound to C3 of glutamate (Glu)

Suppression of synchronous resonance for VSGs [PDF]
The Journal of Engineering, 2017 The virtual synchronous generator (VSG) is an attractive interfacing technique for high-penetration renewable generation. By incorporating the inertia control, the grid-connected voltage-source converter can behave in a similar way with the SGs, which is helpful to enhance the stability of the power system.
