In particular, Γ is an orthogonal array of strength t if and only if F=Rt+1.
Parameters such as fastener array, bond strength and the influence of initial defects are investigated.
The method starts with an orthogonal array of strength 2, possibly tight, that contains mostly 2-level factors.
The morphological changes help to explain the increase in CNT array compressive strength and the transition from permanent array deformation to foam-like recovery after compressive loading.
It is well known that a two-level orthogonal array of strength 2 is universally optimum for the estimation of main effects for uncorrelated errors.
In the interim, mobilize a stunning array of strength, close streets, empty parks, slow traffic, watch the bridges and inconvenience the populace in the process -- men and women who learned long ago that in New York one has to take it as it comes.
A covering array of strength t and order v is an N×k array over Zv with the property that every N×t subarray covers all members of Ztv at least once.
In particular, for every prime power q and every m⩾2 there exists a unique (up to equivalence) complete linear orthogonal array of strength two associated with the classical design of points and hyperplanes in AG(m,q).
For two-level factorials, we consider designs in N=2 (mod 4) runs as obtained by adding two runs, with a certain coincidence pattern, to an orthogonal array of strength two.
A k × N matrix A with entries from a set X of s ≥ 2 symbols is called an orthogonal array of strength t, size N, k constraints, and s levels if each t × N submatrix of A contains all possible t × 1 column vectors with the same frequency λ.
When the construction is based on a resolvable orthogonal array with strength w+1, the resulting design not only possesses stratification in any w-dimensional projection for each slice, but also achieves stratification in any (w+1 -dimensional projection for the w+1 -dimensional
