On Theory and Applications of BIB Designs with Repeated Blocks

Annals of Statistics, 1977
Consider BIB designs with parameters $v, b, r, k$ and $\lambda$. Define the support of a BIB design to be the set of its distinct blocks and let the cardinality of the support be $b^\ast$. If $b^\ast < b$ then the design is said to be a BIB design with repeated blocks.

Recursive constructions for cyclic BIB designs and their generalizations

Discrete Mathematics, 1993
This is a well-written, fairly complete survey of results on recursive techniques for constructing cyclic and 1-rotational block designs. An extensive discussion of the application of such techniques to cyclically nested designs is given. Finally, one construction is generalized to other sharply transitive groups.

BIB(8, 56, 21, 3, 6) and BIB(10, 30, 9, 3, 2) designs with repeated blocks

Journal of Combinatorial Theory - Series A, 1984
AbstractIf there are less than b distinct blocks in a BIB design with b blocks then we say the design has repeated blocks. The set of distinct blocks of a design is called the support of the design. BIB designs with repeated blocks, besides being optimal, have special applications in the design of experiments and controlled samplings.

Effect of Window and Hole Pattern Cut-Outs on Design Optimization of 3D Printed Braces

Frontiers in Rehabilitation Sciences, 2022
BackgroundThere are many different Thoracic Lumbar Sacral Orthosis style brace designs available in the market for the correction of scoliosis deformity. Hole cut out patterns, are commonly used in brace designs. These cut-outs may be subdivided into two

On μ-resolvable BIB designs

Discrete Mathematics, 1983
AbstractIn this paper, some μ-resolvable balanced incomplete block designs are constructed. Furthermore, parameters' combinations of all the designs constructed are tabulated under some restrictions.

R.A.Fisher, design theory, and the Indian connection [PDF]

, 2009
Design Theory, a branch of mathematics, was born out of the experimental statistics research of the population geneticist R. A. Fisher and of Indian mathematical statisticians in the 1930s.

Decoding the Golay code with Venn diagrams [PDF]

, 1990
A decoding algorithm, based on Venn diagrams, for decoding the [23, 12, 7] Golay code is presented. The decoding algorithm is based on the design properties of the parity sets of the code. As for other decoding algorithms for the Golay code, decoding can

Redesign of technical systems [PDF]

, 1995
The paper describes a systematic approach to support the redesign process. Redesign is the adaptation of a technical system in order to meet new specifications.
