The phrase "at certain scales" is correct and usable in written English.
It can be used when discussing phenomena or measurements that vary depending on the size or level of detail being considered.
Example: "The behavior of the material changes at certain scales, affecting its overall performance."
Alternatives: "at specific levels" or "at particular dimensions".
Newtonian physics works at certain scales and speeds, just as Einstein's equations work at other scales and speeds.
The difference between these two numbers highlights how much of an approximation the formula is at certain scales.
The results from the Hyperion radiance data suggest that fractal signatures at certain scales can reveal important differences in land cover types.
Instead of traditional polynomial interpolation, scaling functions at certain scales have been adopted to form the shape functions and construct wavelet-based elements.
However, the teaching and learning of concepts related to size and scale present major challenges because objects at certain scales are unable to be perceived by humans with the naked eye.
Note that we manually generate a few images in some groups as the original image sets lack images at certain scale levels.
"Working at a certain scale allows the company to be more nimble," Robert O'Meara, director of media and communication at ACI Europe, said in an e-mail.
Especially in microsystem design, maintaining the minimum thickness of each structural member at a certain scale is often as important as achieving the maximum system performance.
"No human being can work fast enough to process all the data available at a certain scale," says Mike Lynch, boss of Autonomy, a computing firm that uses algorithms to make sense of unstructured data.
On that basis, the corresponding parameter design optimization and system performance analysis are carried out from the viewpoint of the maximization of the exergy output in KCS-11 solar system at a certain scale.
More important, to regard consciousness and free will as merely "properties" of matter at a certain scale misses the essential point that these are not simply observable characteristics of objects: They are events that are actually experienced but that cannot be quantified as matter or energy and yet are as real as any atom, molecule or organism.
