LDPC Codes on Balanced Incomplete Block Designs: Construction, Girth, and Cycle Structure Analysis [PDF]

open access: yesEntropy
In 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]

open access: yesEntropy
In 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]

open access: yesFrontiers in Communication
Experiments are widely used in communication research to help establish cause and effect, however, studies published in communication journals rarely use discrete choice experiments (DCEs).

Analysis of Covariance of Reinforced Balanced Incomplete Block Designs With a Single Explanatory Variable [PDF]

open access: yesJournal 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.

Balanced incomplete block designs: selected business-related applications and usage caveats [PDF]

open access: yesInnovative Marketing, 2016
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]

open access: yesCanadian Mathematical Bulletin, 1964
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.

Construction of Some Circular Regular Graph Designs in Blocks of Size Four Using Cyclic Shifts

open access: yesJournal of Statistical Theory and Applications (JSTA), 2020
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.
