2. An experiment was run in a semiconductor fabrication plant in an effort to increase yield. Five factors, each at two levels, were studied. The factors (and levels) were A aperture setting (small, large), B-exposure time (20% below nominal, 20% above nominal), C-development time (30s, 45s), D mask dimension (small, large), and E: etch time (145min, 15.5min). The unreplicated 25 design shown below was run. b 34 bd 32 be 35 bde 30 ab 55 abd 50 abe 52 abde...
Need help writing four short recursive programs: Write a program called Permutations.java that takes an integer command-line argument, n, and enumerates all permutations of the first n letters in the English alphabet. Be sure to handle exceptions of the types: i) bad user input (i.e., double, string), ii) n > 26 or n < 0. Write a program called PermutationsK.java that takes two integers, n and k, as command-line arguments and prints out all P(n,k) permutations that contain exactly k...
#). Use a 25-2 design to investigate the effect on process yield of A condensation temperature, B - amount of material 1, C- solvent volume D-condensation time, E amount of material 2. The results obtained are as follows. e-23.2 cd-23.8 ab -15.5 ace-23.4 ad -16.9 bde -16.8 bc-16.2 abcde -18.1 A.) Give the compete defining relation and the aliases from the design. Your input sequence needs to follow alphabetical order. Defining Relation: I ACE -BDE -ABCDE b.) Estimate the main...
4. An experiment was performed to improve the yield of a chemical process. Four factors, A, B, C and D were selected. Suppose that in the chemical process development experiment, it was only possible to run a one-half fraction of the 24 design. Construct the design and perform the statistical analysis, using the data from replicate 1 Treatment Combination Replicate I 90 74 81 83 Treatment Combination Replicate I 98 72 87 85 ad bd cd 81 79 87 ac...
A single replicate 24 experiment is designed. The experiment has factors A, B, C, and D, each of which can be set to +1 or -1. We conduct a single replicate of this experiment, collecting the response for each possible combination of factor settings. This data is in the file HW_DOEInterp_180.csv . We compute the factorial and interaction effects from this data, and determine that the following effects are significant: Factorial Effect B = -15.265 Factorial Effect C = -11.433...
