The phrase "a minimum intensity" is correct and usable in written English.
It can be used in contexts where you are specifying the least amount of intensity required for something, such as in scientific, technical, or artistic discussions.
Example: "To achieve the desired effect in the experiment, we need to maintain a minimum intensity of light."
Alternatives: "the lowest intensity" or "a baseline intensity".
In the middle of the night, the airglow shows a minimum intensity about 28% lower than its maximum value.
A minimum intensity and duration of at least two hours per day and 100 days a year is required (UNESCO 2012).
In this study, the efficiency is boosted by reducing the spectral information to be considered for the analysis, adding a f0 candidate selection process, and pruning unlikely combinations by applying some constraints, like a minimum intensity for a pattern.
"Cindy" (98% HRmax and RPE = 9) also presented an acute blood oxidative stress response similar to a traditional bout of high-intensity treadmill running (running at a minimum intensity of 90% maximum heart rate over 20 min) [47].
The presence of the vinyl group in VTES can usually be recognized by the presence of a minimum intensity of broad band at 3,516 cm−1 due to the unsaturated =C H stretching vibration.
Genes with a minimum intensity of 16 were considered to be expressed.
At low signal levels, a minimum intensity-independent noise level, mainly due to noise contributions of the coupled amplifiers, sets a detectivity of about 0.7×1012 cm Hz1/2 W−1.
The postprocessing procedure mainly requires a minimum-intensity projection technique for airway imaging.
Centrosomes were identified semi-automatically using Volocity by finding objects above a minimum volume with an intensity >3 standard deviations from the mean intensity of the image.
To avoid selecting genes with high foldchange due to low signal intensity a minimum signal intensity value was utilized.
Depending on the optical wavelength, the far-field radiation pattern looks either like a quasihomogeneous optical beam or a torus, having a maximum or minimum intensity at its center, respectively.
