The phrase "at a fixed value" is correct and usable in written English.
It can be used in contexts where you want to specify that something is set or maintained at a specific numerical or qualitative level.
Example: "The temperature in the laboratory must be maintained at a fixed value to ensure accurate results."
Alternatives: "at a constant level" or "set to a specific value."
4. In modern work on CJT (as contrasted with the 18th century version), the theorem has been shown to hold even when one suitably relaxes the requirement of universal competence at a fixed value greater than 0.50.
This vascularization was used as boundary condition: in these vessels oxygen partial pressure, glucose concentration, pH and bicarbonate concentrations were kept at a fixed value.
They show that by fixing DC values at a fixed value and recovering AC coefficients (by known or chosen plaintext attacks), a semantically good reconstruction of the image is obtained.
The forcing frequency is set at a fixed value, in the range 15 120% of the natural shedding frequency of the stationary normal flat plate.
The major drawback that we found was with choosing the gain for the detector that has to be set at a fixed value before starting the experiment.
The allele frequency was therefore not taken into account for power calculation but was set at a fixed value (0.5).
To realize the former, we replaced the composition variable at each pinning site by a fixed value s x, y) = Lo%/50 − 1, where Lo% is the partitioning fraction of the pinning lipid derived experimentally.
To compare maximum cluster size when the number of clusters per gene is the same, rather than at a fixed threshold value, we applied the clustering methods across a range of threshold values and for each gene matched the LDselect and CLQ clustering results according to the number of clusters).
This explains the diminished growth rate or even the inhibition of growth after the addition of butyric acid at a fixed pH value, or the extended lag period or growth failure if butyric acid was added at the beginning at pH set value of 6 or 5.5, respectively.
In the first set we fixed and and vary and at a fixed SNR value.
The measurements were performed at a fixed pH value (7.5), using NaOH.
