"upper diameter" is correct and usable in written English.
It can be used to refer to the diameter of something that is located at the upper end of something, typically in the context of describing some kind of shape or size. For example, "The upper diameter of the cylinder was two inches."
Design sensitivity analysis showed increasing the height and upper diameter of the scaffold can tremendously reduce the TD and EQV of the model, while increasing the bottom diameter of scaffold can, to some extent, reduce the EQV in post.
The optimal scaffold adopted a slightly tapered shape with the upper diameter of 4.9 mm, bottom diameter of 3.4 mm; the length of the optimized scaffold shape was 9.4 mm.
In order to produce sound ingot, a new 2. 8 t ingot mould was designed which includes some parameteric changes in mould such as mould slope, slenderness ratio, mould concavity radius, fillet radius of mould internal corners and feeding diameter to ingot upper diameter ratio.
The under side of the architrave is to be as wide as the upper diameter of the column, at the part under the capital; its upper part equal in width to the lower diameter of the column.
Likewise, the number of subsample trees and the selection of measurements taken from each tree (e.g. height and/or upper diameter) can be difficult to account for in detail in an analytical setting.
Seedlings with a similar size were transplanted individually into plastic pots (26 × 20 × 28 cm; upper diameter × lower diameter × height) in June 2011 and all plants were fully watered to ensure healthy growth.
The diameter at breast height (d1.3) is measured for all tally trees, but height, upper diameters, age, and growth are measured only for subsample trees.
For the BASE model, parameter β 1 is constrained to dbh, and for models M3_HABH and GB99, parameter β 1 is constrained to dbh and β 2 to the upper stem diameter (diameter at 6 m for the GB99 model).
Belleville washer (or) disk spring with higher height to thickness ratio i.e. (h/t) is made with a bearing flat at upper Inner Diameter (I.D) and lower Outer Diameter (I.D) with appropriate radius over edge.
In the experiments, a number of parameters such as the edge distance-to- upper hole diameter (E/D), the distance between center of two holes-to-hole diameter (K/D), and the width of the specimen-to-hole diameter (W/D) were varied.
The authors did not evaluate the role of the upper stem diameter in this equation nor did they evaluate other upper stem diameter measurements.
