The authors wish to make the following corrections to this paper [1]:
There was an error in the original article. Equations (3) and (4) are incorrect:
Using the determined parameter $B$, displacements in the directions of the $x$ and $y$ axes can be calculated using Equations (3) and (4), respectively:
$d ALD = B ∂ d v ∂ ALD ,$
$d ALD = B ∂ d v ∂ ALD .$
A correction has been made to the Research Methodology Section:
Using the determined parameter $B$, displacements in the directions of the $x$ and $y$ axes can be calculated using Equations (3) and (4), respectively:
$d x = B ∂ d v ∂ x ,$
$d y = B ∂ d v ∂ y .$
The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. The original article has been updated.
