3-Group Divisible Designs with 3 Groups and Block Size 5
A 3-GDD (n, 2, k, λ1, λ2) was defined by combining the definitions of a group divisible design and a t-design. In this paper, we extend the definitions to 3 groups and block size 5, and we denote such GDD by 3-GDD (n, 3, 5, μ1, μ2).

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 ...

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 block designs with repeated blocks
This paper is concerned with balanced incomplete block designs in which repeated blocks are allowed. If \({\mathcal D}\) is such a \((v,k,\lambda)\)- design (using the standard notation), let \(b^*\) denote the number of distinct blocks. Let \(BIBD(v,k,\lambda| b^*)\) denote the family of all such designs \({\mathcal D}\). Fixing the number of points \(

Blocking Sets in Designs with Block Size 4
Constructions are given which produce block designs with \(\lambda=1\) or 2 and \(k=4\) admitting a blocking set. The construction includes all admissible orders \(n\) with \(\lambda=1,2\) and \(k=4\) except 8 cases. There are four separate constructions, one for \(\lambda=1\) and \(n\equiv1\) mod 12, one for \(\lambda=1\) and \(n\equiv 4\) mod 12, one

The selection of optimal designs for generalized linear mixed models is complicated by the fact that the Fisher information matrix, on which most optimality criteria depend, is computationally expensive to evaluate.

In mixture experiments, the observed response is determined by the relative proportions of the components, consequently rendering the experimental region a simplex.

Optimal Designs for Proportional Interference Models with Different Guarding Strategies
Interference models are commonly used in agriculture, industry, and other related fields. Optimal designs for these models are important topics in block designs.

Three-way cross designs for animal breeding experiments
Three-way crossbreeding has been a major tool for the development of present day commercial breeds. The hybrids thus produced are more stable and they exhibit individual as well as population buffering mechanism because of the broad genetic base.

ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
