Incomplete orthogonal arrays and idempotent orthogonal arrays
Graphs and Combinatorics, 1996The author introduces a notion of idempotency of orthogonal arrays (OA) of index unity, and the notion of incomplete OA. Denote by \(\text{OA}_\lambda(t,r,s)\) an array with \(r\) rows and \(\lambda s^t\) columns, with entries taken from an \(s\)-set \(E\), such that in each set of \(t\) rows every \(t\)-tuple of entries occurs precisely \(\lambda ...

Optimal split‐plot orthogonal arrays
Australian & New Zealand Journal of Statistics, 2017SummaryIt is well known that many industrial experiments have split‐plot structures. Compared to completely randomised experiments, split‐plot designs are more economical and thus have received much attention among researchers. Much work has been done for two‐level split‐plot designs.

Constructions of Nested Orthogonal Arrays
Journal of Combinatorial Designs, 2013AbstractA symmetric nested orthogonal array, denoted by NOA, is an OA which contains an OA as a subarray, where . Nested orthogonal arrays are useful in designing an experimental setup consisting of two experiments, the expensive one of higher accuracy being nested in a relatively less expensive one of lower accuracy.

In this chapter we investigate orthogonal arrays in which the various factors may have different numbers of levels — these are called mixed or asymmetrical orthogonal arrays.

The Orthogonal Transfer Array (OTA) is a monolithic array of small CCDs that are 4-side buttable and can be mosaicked to make the 40K×40K focal plane required by Pan-STARRS. These devices have other interesting properties such as a 'Deep Depletion' structure which enables 75 µm thick devices to be fully depleted with modest charge diffusion, while ...

Orthogonally-Oriented Nanotube Arrays: Theory
Journal of Nanoscience and Nanotechnology, 2006A novel surface involving ordered arrays of partially-embedded carbon nanotubes is developed theoretically. Analysis indicates it should exhibit ultra-low values for friction, adhesion and wear, and also possess superior thermal and electrical properties.

This chapter contains several tables: (a) Tables showing the smallest possible index (and hence the smallest number of runs) in 2-, 3- and 4-level orthogonal arrays with at most 32 factors and strengths between 2 and 10. (b) Tables summarizing most of the arrays constructed in this book, including a table of both mixed-and fixed-level orthogonal arrays

Doubly Orthogonal Equi‐Squares and Sliced Orthogonal Arrays
Journal of Combinatorial DesignsABSTRACTWe introduce doubly orthogonal equi‐squares. Using linear algebra over finite fields, we produce large families of mutually ‐doubly orthogonal equi‐ squares, and show these are of maximal size when . These results specialize to the results of Xu, Haaland, and Qian when and the equi‐squares are Sudoku Latin squares of order .
