New Stilling Basins Designs for Deep Rectangular Outlets
The experimental study reported here is intended to evolve new designs of stilling basins for deep and narrow openings used as outlets. Several appurtenances such as grid, Impact wall, stepped wall, weir wall, sloping end sill and wedge shaped blocks are used to study their influence on the hydraulic performance of the stilling basins with an aim to propose efficient stilling basin models. All ...
متن کاملNew spherical 4-designs
Hardin, R.H. and N.J.A. Sloane, New spherical 4-designs, Discrete Mathematics 106/107 (1992) 255-264. This paper gives a number of new spherical 4-designs, and presents numerical evidence that spherical 4-designs containing n points in k-dimensional space with k G 8 exist precisely for the following values of n and k: n even and 22 for k = 1; n 2 5 for k = 2; n = 12, 14, >I6 for k=3;n~2Ofork=4;...
متن کاملNew Box-Behnken designs
Box and Behnken (1960) constructed 10 three-level, second-order designs, while their 1958 technical report contained seven additional designs. This series of designs is based on combining 2 or 2 designs in different subsets of the t factors, with k < t. The subsets of size k were determined using balanced (or partially balanced) incomplete block designs. This present article offers additional B...
متن کاملSome New 4-Designs
The existence question for the family of 4-(15, 5, λ) designs has long been answered for all values of λ except λ = 2. Here, we resolve this last undecided case and prove that 4-(15, 5, 2) designs are constructible.
متن کاملNew Constructions of Lotto Designs
An LD(n, k, p, t; b) Lotto Design is a set of b k-sets (blocks) of an n-set such that any p-set intersects at least one k-set in t or more elements. Let L(n, k, p, t) denote the minimum number of blocks in any LD(n, k, p, t; b) Lotto Design. We shall discuss several techniques for constructing Lotto designs and determining upper bounds for L(n, k, p, t).
