  natural frequency
This study investigated the dynamic modulus of elasticity (DMOE) of wood panels of Fraxinus mandshurica, Pinus koraiensis, and Juglans mandshurica using the natural frequency measurement system of fast Fourier transform (FFT).
      
The natural frequency reached 1.201-kHz using finite element analysis, and the practice measurement result was 1-kHz.
      
Using the differentials of a stiffness matrix to design parameters, a method for calculating the sensitivity of natural frequency is presented.
      
Through the mode analysis of the liquid-solid coupled system, the first-order natural frequency, diaphragm vibration shape and amplitude-frequency relationship are obtained.
      
The natural frequency of the system was less than that of the structure on rigid foundation if the SSI is not taken into account, while its damping ratio was larger than that of the structure.

  inherent frequency
Code combining is used to exploit the multiple signal copies resulting from the inherent frequency diversity of spread spectrum.
      
Even though the gain due to selection in frequency selective channels is reduced compared to that in flat fading channels due to the inherent frequency diversity, the performance improvement is significant when the system is interference limited.
      
Each device operates at some inherent frequency, with wide variation among devices.
      
The windowing helps by reducing the inherent frequency broadening of each interferer caused by the finite duration of the FFT.
      
  intrinsic frequency
On this assumption, deviations of the Zeitgeber-frequency from the intrinsic frequency of the dependent systems cause phase-angle differences between the two systems.
      
Also, with short and relatively weak intersegmental connections, the network remains robust against perturbations as well as intrinsic frequency differences along the chain.
      
The temporal variation of the tidal component of the wind changes the observed frequency, sometimes substantially, while leaving the intrinsic frequency unaltered.

Numerical evidence is given here that the family of such orbits is a continuous function of the rotation frequency Ω which varies between Ω?=?0, for the planar figure eight orbit with intrinsic frequency ω, and Ω =?ω for the circular Lagrange orbit.

  resonant frequency
The simulated results show that FSS may operate in different bands and especially generate a large reduction in the resonant frequency for a fixed unit cell size through different loadings.
      
Because of coupling of the mechanical and magnetic effects, coupled magnetoacoustic oscillations of a wave nature develop in a certain (resonant) frequency region.
      
It is found that such a system possesses a rather interesting nontrivial property: under certain conditions it has a resonant frequency at which the rotation of the particles relative to the fluid is most intense.
      
The dependence of the resonant frequency on the tube length is investigated.
      
The technique involves measuring the resonant frequency and Q factor of a microwave cavity containing a poly-Si specimen, on which basis the relative permittivity εr and the dissipation factor tanδ are calculated.
