How To Perform a Wet Sieving Analysis - W.S. Tyler

WebThe first deterministic primality test significantly faster than the naive methods was the cyclotomy test; its runtime can be proven to be O((log n) c log log log n), where n is the number to test for primality and c is a constant independent of n. Many further improvements were made, but none could be proven to have polynomial running time. WebChapter <786> of USP32-NF27 provides a description of the testing method for the measurement of particle size distribution of a powder by the sieve analysis method.
