The phrase "a small distortion in" is correct and usable in written English.
It can be used when describing a minor alteration or change in something, often in a technical or artistic context.
Example: "The artist noticed a small distortion in the image after applying the filter."
Alternatives: "a slight alteration in" or "a minor change in".
The Moon does cause a small distortion in the Earth's shape, but as everyone knows, the major effect is tides on the ocean.
That is, a small distortion in the capital-effort ratio away from the optimal ratio results in a larger and larger decrease in information rents.
Our results also demonstrated a small distortion in the video objective quality, a small increment in bit-rate, and embedded cost savings of −2.6196% for high and medium motion video sequences.
The β2-strand is much more defined through interactions with the β1 strand in the crystal structure with the wild type sequence, XRAY1, although even in this structure a small distortion from regular β-sheet geometry is apparent due to the bulging out of a single amino acid, Q237.
A small distortion, as another criterion for stability, has been observed in C- and Si-doped BNT systems.
The B-terminated vacancy structures after relaxation result in small distortion in their vertex region with weakly binding between B atoms (not shown here) while the N-terminated structures shows a distinct change at the vertices of their triangular vacancy.
Although we use PSNR for evaluation of the encoding results in Section 3, PSNR cannot show properly the effect of prediction errors (lost I- and P-pictures), which might be highly visible but create small distortion in terms of mean square error, or even of reduced frame rate by the loss of nonreferenced p-pictures.
Although still α-helical, small distortions in the final structures around glycine 15 result in a slightly bent α-helix.
When moving along the structure, the moving vehicle causes small distortions in the dynamic response of the bridge vehicle system at the crack locations.
In addition to the simple fact that free electrons are captured by protons and helium ions also some photons are released in the cosmological recombination process, leading to small distortions in the CMB blackbody spectrum which should still be present today.
An implication of stability is that small perturbations in the signal caused by noise result in small distortions in the output solution.
