The phrase 'under the frequency' is correct and usable in written English.
It is used to describe something that is happening at a rate or speed that is lower than the norm. For example, "We noticed that student attendance has dropped off under the frequency of previous months."
Axially fully-reversed fatigue test of a low strength Cr Ni Mo V steel welded joint was conducted up to the very high cycle fatigue regime under the frequency of 110 Hz and 20 kHz.
As a quantitative performance measure, the H2 norm, which is related to the area under the frequency response function, is calculated and compared for both the metastructure and the baseline structure.
Fatigue crack growth under the frequency of 0.01 Hz was predominantly intergranular and time-dependent, while that under frequencies of 1 and 0.1 Hz was of mixed type but still cycle-dependent.
Dynamic mechanical studies revealed that polyurea remains as an elastomer under the frequency range associated with the shock tube testing and behaves as a catcher system for the fragments formed due to blast loading.
It was found that the stress ratio had no influence on fatigue crack growth behavior under the frequency of 10 Hz due to cycle-dependent crack growth without crack closure.
The three iterations of antenna is designed and simulated by using HFSS V13 software and the designed antennas covers the frequency bands of WLAN, WiMax and other wireless applications which comes under the frequency ranges of S-band, C-band and X-band.
Sampling to estimate a mean routinely under-estimates the frequency of extreme events, and thus under-estimates extinction risk.
This historical period has been shown to under-represent the frequency of high-magnitude events.
Some patients may have blunted hypoglycemic awareness and may under-report the frequency of events because they do not consistently experience the symptoms typically associated with hypoglycemia.
Numerical results under the frequency-selective MIMO-OFDM channel, which is generated by the classical Zheng and Xiao's model, prove that the proposed transceiver can significantly reduce the feedback overhead without severe performance degradation.
Under the frequency-division multiplexing (FDM) system, let h i denote the M×1 forward channel vector from the ith transmitter to all receivers and g i denote the M×1 reverse channel vector from ith receiver to all transmitters.
