Construction of Some Circular Regular Graph Designs in Blocks of Size Four Using Cyclic Shifts
Circular regular graph designs play an important role in the design of experiments where most of the balanced incomplete block designs require a large number of blocks.

Balanced incomplete block designs: selected business-related applications and usage caveats [PDF]
Whenever respondents must rank-order a large number of items and/or the reliability of their rankings may be questionable, balanced incomplete block designs (BIBDs) represent a more effective means for doing so than either complete rankings or paired ...

Block Intersections in Balanced Incomplete Block Designs [PDF]
One of the most interesting of the smaller BIBD's is the system (8, 14, 7, 4, 3), where we write the parameters in the standard order v, b, r, k, λ. One representation of a design with these parameters is 1248, 3567; 2358, 1467; 3468, 1257; 4578, 1236; 5618,2347; 6728,1345; 7138,2456.

On the Composition of Balanced Incomplete Block Designs [PDF]
The object of this paper is to develop a method of constructing balanced incomplete block designs. It consists in utilizing the existence of two balanced incomplete block designs to obtain another such design by what may be called the method of composition.1. Preliminary results on orthogonal arrays and balanced incomplete block designs.

New Results Regarding the Construction Method for D‑optimal Chemical Balance Weighing Designs
We study an experiment in which we determine unknown measurements of p objects in n weighing operations according to the model of the chemical balance weighing design. We determine a design which is D‑optimal. For the construction of the D‑optimal design,

On incomplete and balanced incomplete block designs [PDF]
By an incomplete block design we will mean an arrangement of v different varieties of objects in b distinct blocks or sets such that a block does not contain all the varieties and a variety appears at most once in a block. An incomplete block design which satisfies two extra conditions, viz.

Optimum Choice of Covariates for a Series of SBIBDS Obtained Through Projective Geometry [PDF]
A block design set up is considered in presence of a number of controllable covariates. The problem is that of choosing the values of the covariates so that for a given block design, it is optimum in the sense of attaining minimum variance for the ...

On the Classification of Splitting (v, u×c, λ) BIBDs
The (v, u×c, λ)-splitting balanced incomplete block designs correspond to c-splitting authentication codes. We classify splitting balanced incomplete block designs with definite parameters.

On quasi-orthogonal cocycles [PDF]
We introduce the notion of quasi-orthogonal cocycle. This is motivated in part by the maximal determinant problem for square {±1}-matrices of size congruent to 2 modulo 4. Quasi-orthogonal cocycles are analogous to the orthogonal cocycles of algebraic
