Soil structure resonance can take place when the new shifted site frequency coincides with the structural frequency: The "spectral coincidence" effect is thus shifted toward f struct/f soil values lower than 1.
In the current study, the incoming wave frequency is set such that third-harmonic wave frequency coincides with the first tower bending mode frequency.
In addition, if the source pulsation frequency coincides with one of the natural frequencies of the piping network, resonance will take place and the vibrations will be magnified to a large scale.
It is revealed that if the compression phase of the coupling frequency coincides with the transient collapse of the bubble initiated by the base frequency, the intensity of the collapse receives an additional boost resulting in greater production of radicals.
At the voltage value where the corresponding axial frequency coincides with the tank circuit frequency, resonant energy transfer from the circuit to the oscillating electrons results in a dip in the demodulated DC output of the circuit.
Analysis of V z and foF2 curves indicates that the increase in the critical frequency coincides basically with upward direction of drift, and that the decrease corresponds to downward drift.
Results show that for a periodically, elastically supported beam subjected to a nearly stationary force, an acoustic radiation peak occurs when the excitation frequency coincides with one of the bounding frequencies of the propagation zones.
The present study shows that when the damping coefficient, TMD mass (mD), TMD initial displacement (A) and nonlinear spring constant of the NLTMD fulfill a function relationshipλ= 3mDβA, the damping and nonlinear elastic effects cancel each other out, and the nonlinear damping frequency coincides with the linear natural frequency.
Due to the time-varying length of the vertical cable the natural frequencies of the system vary slowly, and a transient resonance may occur when one of the frequencies coincides with the frequency of an external excitation at some critical time.
Gain-loss frequency coincides closely with the results of AACC and BBDD.
