Pairwise balanced designs from nite elds
نویسنده
چکیده
Developing previous work by R.C. Bose, R.M. Wilson, M. Greig and the author, we give a general construction for di erence families over nite elds. All the DFs constructed before were generated by a single initial base block so that they were uniform. Here we also consider DFs generated by two or more initial base blocks. These DFs give rise to pairwise balanced designs which of course are balanced block designs exactly when the initial base blocks have constant size. c © 1999 Elsevier Science B.V.

A New Technique For Constructing Pairwise Balanced Designs From Groups
We introduce a new technique for constructing pairwise balanced designs and group divisible designs from finite groups. These constructed designs do not give designs with new parameters but our construction gives rise to designs having a transitive automorphism group that also preserves the resolution classes.
متن کاملResolvable partially pairwise balanced designs and their applications in computer experiments ∗
The uniform design is one of major designs in computer experiments. In this paper, we develop the connection among the computer experiments, uniform designs in statistics and resolvable partially pairwise balanced designs (RPPBDs) from design theory. A series of RPPBDs with special requirements are constructed and used to produce new uniform designs under the discrete discrepancy.

متن کاملAn asymptotic existence result on compressed sensing matrices
For any rational number h and all sufficiently large n we give a deterministic construction for an n× bhnc compressed sensing matrix with (`1, t)-recoverability where t = O( √ n). Our method uses pairwise balanced designs and complex Hadamard matrices in the construction of -equiangular frames, which we introduce as a generalisation of equiangular tight frames. The method is general and produce...
متن کاملPairwise additive 1-rotational BIB designs with λ=1
The existence of pairwise additive balanced incomplete block (BIB) designs and pairwise additive cyclic BIB designs with λ = 1 has been discussed through direct and recursive constructions in the literature. This paper takes BIB designs with 1-rotational automorphisms and then the existence of pairwise additive 1-rotational BIB designs is investigated for λ = 1. Finally, it is shown that there ...
