LDPC Codes on Balanced Incomplete Block Designs: Construction, Girth, and Cycle Structure Analysis [PDF]
EntropyIn this paper, we investigate the cycle structure inherent in the Tanner graphs of low-density parity-check (LDPC) codes constructed from balanced incomplete block designs (BIBDs).

Construction of Binary Locally Repairable Codes with Nonuniform Locality and Availability Using Combinatorial Designs [PDF]
EntropyIn this paper, we generalize the construction of locally repairable codes (LRCs) by leveraging pairwise balanced designs (PBDs) and balanced incomplete block designs (BIBDs) to construct codes with nonuniform locality or nonuniform availability.

Discrete choice experiments: a primer for the communication researcher [PDF]
Frontiers in CommunicationExperiments are widely used in communication research to help establish cause and effect, however, studies published in communication journals rarely use discrete choice experiments (DCEs).

Resistance of Balanced Incomplete Block Designs
Annals of Statistics, 1975 Hedayat and John (1974) studied the case of resistance of a balanced incomplete block design (BIBD) to the removal of one treatment. They showed that a necessary and sufficient condition for a BIBD to be resistant (that is, retain its variance balance) upon removal of a single treatment is that the two proper subdesigns created by this removal be BIBDs.

Robustness of Balanced Incomplete Block Designs
Annals of Statistics, 1976 When a variety is lost or omitted from a balanced incomplete block design, the residual design is not, in general, balanced. A lower bound is obtained for the overall efficiency in this case and it is shown that the overall loss of efficiency even in the unbalanced case is small.

A Statistical Model for the 2-Part Balanced Incomplete Block Design
UMYU Scientifica Journal, 2023 Multi-part Balanced Incomplete Block Designs combine many orthogonal balanced incomplete block designs in the same block. The design has been used to study cancer trials with medical centres as blocks.

Analysis of Covariance of Reinforced Balanced Incomplete Block Designs With a Single Explanatory Variable [PDF]
Journal of Statistical Theory and Applications (JSTA), 2014 Reinforced balanced incomplete block designs (BIBDs) are very useful in statistical planning of experiments as they can be constructed for any number of treatments for given numbers of replications.

On balanced incomplete-block designs with repeated blocks [PDF]
European Journal of Combinatorics, 2007 In this highly informative paper, balanced incomplete block designs (BIBDs or \(2\)-designs) mainly with repeated blocks are studied. Along with this, results on several other types of designs such as \(t\)-designs, \(t\)-wise balanced designs and designs with different block sizes are also obtained. Initial results in this direction date back to R. C.
