Orthogonal Arrays of Strength two and three 来自 Semantic Scholar 喜欢 0 阅读量: 245 作者:RC Bose,KA Bush 摘要: Orthogonal arrays can be regarded as natural generalizations of orthogonal Latin squares, and are useful in various problems of experimental design. In this paper the known upper ...
To further improve the space-filling properties in low dimensions while possessing the column orthogonality, we propose column-orthogonal strong orthogonal arrays of strength two star and three. Construction methods and characterizations of such designs are provided. The resulting strong orthogonal arrays,...
For OAs with two levels and strength 2, see also the accompanyingTable of Hadamard Matrices(sometimes also calledPlackett-Burmandesigns). That there is also a table showing the parameters of all knownorthogonal arrays of strength 2 and up to 100 runs(both mixed and unmixed). That table lists...

Abstract The purpose of this paper is to survey the construction of orthogonal arrays of strength two by using difference sets. Some methods for constructing difference setD(2p,2p,p,2), wherepis a prime or a prime power, are given. It is shown that the Kronecker sum of a difference set...
All-pairs testing is a very powerful technique for reducing the number of tests to be run, but there are two problems to consider. The first problem is that if the defect in are example requires three variables to be just so (Destination=Canada, Class=Business, and Seat Preference=Aisle),...

3-uniform states and orthogonal arrays of strength 33-uniform statesorthogonal arraysHadamard matricesA pure quantum state of N subsystems with d levels is called k -uniform state if all its reductions to k qudits are maximally mixed. We construct 3-uniform states for an arbitrary number of N...
(Similarly one might consider orthogonal arrays of strength t, that is r×nt matrices A over S. such that for any t rows i1,…, it and any t symbols s1,…, st there is a unique column j such that aikj = sk (1⩽k⩽t). See also page 190 of [DK]. Unless the contrary ...
