The phrase "a frequency close to" is grammatically correct and is commonly used in written English.
It is typically used to describe a value or measurement that is similar or near to a specific frequency. Example: "The study found that individuals who exercised regularly had a frequency close to 70 beats per minute for their resting heart rate." In this example, the phrase "a frequency close to" is used to describe the resting heart rate of individuals who exercise regularly. It indicates that their resting heart rate is near or similar to 70 beats per minute.
The forcing is harmonic, with a frequency close to the natural frequency ωkn of one asymmetric mode of the plate.
Mild surge occurs independently or appears within a deep surge cycle with a frequency close to the Helmholtz resonant frequency of the compression system.
Sub-wavelength metallic structures, when illuminated with a frequency close to the plasma frequency of the metal, present resonances that cause extreme local field enhancements.
The oil whirl phenomenon occurs when the journal bearings are lightly loaded and the shaft is whirling at a frequency close to one-half of rotor angular speed.
A truck-trailer system is assumed, equipped with an external excitation at a frequency close to one of the bridge natural frequencies.
A previous conclusion that coincidence occurs at a frequency close to the cut-off frequency of the acoustic mode involved is confirmed.
The idea is to get shoppers into the megastore with a frequency closer to their need to fill up with gas than to their ability to go through a 24-pack of paper towels.
Hepacivirus and insect-only Flavivirus dinucleotide odds ratio values deviate less from expectation than the other viral groups, indicating that these viral groups are using dinucleotides at a frequency closer to the expected usage values.
For each locus, the allele that had a frequency closest to 0.5 was recoded as 1, while all other alleles were recoded as 2 following Solberg et al. [34] while differing from the rule used by Meuwissen et al. [1], in which only part of the putative loci were polymorphic and available for data analysis.
Finite element method (FEM) was used to model optimum tuning fork geometry, tine tip and tine surface electrode shape and thickness with a resonance frequency close to 32.768 kHz and a series resistance value of 50 kΩ as design targets.
Interestingly, a considerable number of genes show a principal frequency close to two cycles per day, which corresponds to genes that oscillate with a period of 12 hours.
