E being modulus of elasticity (N/mm); L being support span (mm); m being gradient of the initial straight-line portion of the load deflection curve (N/mm); b being width of tested specimen (mm); d being thickness of tested specimen (mm).

In this section, we examine the relationship between the aspect ratio measured using ImageJ software (ARI) and the widths of test ellipse images (Fig. 4), which were obtained by subjecting the test circle images in Fig. 2 to 10%% aspect ratio deformation intervals in Adobe Photoshop CS4.
They conclude " that all items work together, but several problems are noticeable: poor targeting of the test on the population, too small separation of items in the middle of the test, too small width of the test, and the lack of easy items" (2010, p. 7).
At each step during simulated tests, the model determines the apparent retinal width of the test landmark, finds the nearest matching entry in the look-up table (either smaller or larger), and retrieves the desired retinal edge position(s).
The width of fatigue test specimen should be at least 30% of the as-weld sample for fatigue design in consideration of the residual stress relaxation.
The reproducibility of the μPAD fabrication for hydrophilic channel width of the test zone and sample zone was 1.48% and 6.30%, respectively.
First, the test items were developed by using a restricted set of vocabulary and grammar structures (see the "Methods" section), which limited the sentence complexity and vocabulary width of the test prompts (i.e., dialogs).
In this way, we can estimate the values of the casing thickness, the thickness of the liquid layer outside the casing, and the annular space width of the testing model.In the testing model, the thickness of the liquid layer outside the casing, the annular space width, and the casing thickness are 3, 28, and 8 mm, respectively (i.e., ( d_{2}^ ) = 8 mm, ( d_{3}^ ) = 3 mm, ( d_{text{g}}^ ) = 28 mm).
Figure 4 shows the crack width of the tested beams.
