Clique decompositions of multipartite graphs and completion of Latin squares [PDF]

open access: yes, 2017
Our main result essentially reduces the problem of finding an edge-decomposition of a balanced r-partite graph of large minimum degree into r-cliques to the problem of finding a fractional r-clique decomposition or an approximate one.

Low-Density Parity-Check Codes From Transversal Designs With Improved Stopping Set Distributions [PDF]

open access: yes, 2013
This paper examines the construction of low-density parity-check (LDPC) codes from transversal designs based on sets of mutually orthogonal Latin squares (MOLS). By transferring the concept of configurations in combinatorial designs to the level of Latin

On Weighted-Sum Orthogonal Latin Squares and Secret Sharing

open access: yesIACR Cryptology ePrint Archive, 2023
Latin squares are a classical and well-studied topic of discrete mathematics, and recently Takeuti and Adachi (IACR ePrint, 2023) proposed (2 , n ) -threshold secret sharing based on mutually orthogonal Latin squares (MOLS). Hence efficient constructions

On seven mutually orthogonal Latin squares

open access: yesDiscrete Mathematics, 1977
AbstractLet N(n) denote the maximum number of mutually orthogonal Latin squares of order n. It is shown that N(n)⩾7 for n > 4922.

Three mutually orthogonal Latin squares

open access: yesJournal of Combinatorial Theory, Series A, 1972
AbstractIn a famous paper [3], Bose, Shrikhande, and Parker proved the existence of a pair of orthogonal Latin squares of order v for all v ≠ 2,6. In the present paper it is shown that there exist three mutually orthogonal Latin squares for all v ≡ 0,1 (mod 4). This result will be needed in several future papers on the covering of pairs by quadruples.

Discrete phase-space approach to mutually orthogonal Latin squares

open access: yes, 2014
We show there is a natural connection between Latin squares and commutative sets of monomials defining geometric structures in finite phase-space of prime power dimensions.

Maximal sets of mutually orthogonal Latin squares

open access: yesDiscrete Mathematics, 1999
The authors present some new constructions for maximal sets of mutually orthogonal Latin squares. As an application, they provide examples for 24 previously open cases in the table by \textit{A. B. Evans} in [The CRC handbook of combinatorial designs, eds. C. J. Colbourn and J. H.

Tournament Design in Doubles Pickleball

open access: yesInternational Journal of Racket Sports Science
This paper considers a common tournament design in doubles pickleball where N players compete across n matches. The research question involves the assignment of partners and opponents over the n matches.

Reciprocity on the Edge of Distance Paradox: How Sustainability Motives and Hypocrisy Shape Consumer Responses to Nearshoring

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Despite growing interest in corporate relocation decisions and sustainability, the existing literature is limited in its consumer‐centric approach. Integrating social exchange theory and construal level theory, this research investigates how consumers perceive sustainability‐driven nearshoring motives (i.e., socio‐economic vs.

Repairable Replication-based Storage Systems Using Resolvable Designs [PDF]

open access: yes, 2012
We consider the design of regenerating codes for distributed storage systems at the minimum bandwidth regeneration (MBR) point. The codes allow for a repair process that is exact and uncoded, but table-based. These codes were introduced in prior work and
