In "Orthogonal Design for Process Optimization and Its Application to Plasma Etching" (Solid State Technology, May 1987), G. Z. Yin and
D. W. Jillie describe an experiment to determine the effect of C2Fe flow rate on the uniformity of the etch on a silicon wafer used in
integrated circuit manufacturing. Three flow rates are used in the experiment, and the resulting uniformity (in percent) for six
replicates is shown below.

Recently there has been increased use of stainless steel claddings in industrial settings. Claddings are used to finish the exterior walls of a building and help weatherproof the structure. To ensure the quality of claddings, it is essential to know how welding parameters impact the cladding process. The authors of “Mathematical Modeling of Weld Bead Geometry, Quality, and Productivity for Stainless Steel Claddings Deposited by FCAW” (J. Mater. Engr. Perform., 2012: 1862–1872) in vestigated how y 5 deposition rate was influenced by x1 = feed rate (Wf , in m/min) and x2 = welding speed (S, in cm/min). The following 22 observations correspond to the experiment condition where applied voltage was less than 30v:

- Concrete admixtures are natural or manufactured chemicals added during concrete mixing to enhance specific properties of the fresh or hardened concrete, such as workability, durability, or early and final strength. Two admixtures are being tested to determine how they affect the strength of the concrete. Both admixtures are in use but admixture 2 is cheaper and it should be adopted provided that it does not affect the compressive strength of the concrete.
