More on exact bicoverings of 12 points
The minimum number of incomplete blocks required to cover, exactly λ times, all t-element subsets from a set V of cardinality v (v > t) is denoted by g(λ, t; v). The value of g(2, 2; v) is known for v = 3, 4, . . . , 11. It was previously known that 14 ≤ g(2, 2; 12) ≤ 16. We prove that g(2, 2; 12) ≥ 15.

Kathryn Maitland, Charles Newton, Kevin Marsh, Mike Levin The study by Planche et al. [1] provides important new information addressing intracellular volume depletion in children with severe childhood malaria, but does not address the question of whether intravascular volume depletion (hypovolemic shock) is present. Using sophisticated methodology to determine total body water and extracellular...
متن کاملOnce More about 80 Steiner Triple Systems on 15 Points Once More about 80 Steiner Triple Systems on 15 Points
Subsets of a v-set are in one-to-one correspondence with vertices of a v-dimensional unit cube, a Delaunay polytope of the lattice Z v. All vertices of the same cardinality k generate a (v?1)-dimensional root lattice A v?1 and are vertices of the Delaunay polytope P(v; k) of the lattice A v?1. Hence k-blocks of a t ? (v; k;) design, being identiied with vertices of P(v; k), generate a sub-latti...
متن کاملDistillation pinch points and more
Rising energy costs have spawned renewed interest in improving methodologies for the synthesis, design and/or retrofitting of separation rocesses. It is well known that energy use in many process industries is dominated by separation tasks—particularly distillation. In this work, the hortest stripping line approach recently proposed by Lucia, Amale, & Taylor (2006) is used to find minimum energ...
متن کاملMore on stationnary points in Independent Component Analysis
In this paper, we will focus on the problem of blind source separation for independent and identically distributed variables (iid). The problem may be stated as follows: we observe a linear (unknown) mixture of k iid variables (the sources), and we want to recover either the sources or the linear mapping. We give online stability conditions of the algorithm using the eigenvalues of the hessian ...
