Graph design for data authentication over insecure communication channel

open access: yesAlexandria Engineering Journal, 2023
Data authentication is a critical issue in communication systems. Based on data authentication techniques, the receiver can affirm that the data is really sent from an authentic sender and it is not a fabricated message from an opponent.

Orthogonality for Quantum Latin Isometry Squares [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2019
Goyeneche et al recently proposed a notion of orthogonality for quantum Latin squares, and showed that orthogonal quantum Latin squares yield quantum codes.

Integer and Constraint Programming Revisited for Mutually Orthogonal Latin Squares (Student Abstract)

open access: yesAAAI Conference on Artificial Intelligence, 2022
We use integer programming (IP) and constraint programming (CP) to search for sets of mutually orthogonal latin squares (MOLS). We improve the performance of the solvers by formulating an extended symmetry breaking method and provide an alternative CP ...

THE CONSTRUCTION AND MAXIMAL SET OF MUTUALLY ORTHOGONAL LATIN SQUARES [PDF]

open access: yesمجلة جامعة الانبار للعلوم الصرفة, 2012
Given aset of permutation {p1,p2, … . pk} on aset S, we say that the set of permutation is transitive on S if for every ordered pair of elements a,b € S, there exists at least on Pi for which (a) Pi=b.

QC-LDPC Codes From Difference Matrices and Difference Covering Arrays

open access: yesIEEE Access, 2023
We give a framework that generalizes LDPC code constructions using transversal designs or related structures such as mutually orthogonal Latin squares. Our constructions offer a broader range of code lengths and codes rates. Similar earlier constructions

Isometry invariant permutation codes and mutually orthogonal Latin squares [PDF]

open access: yesJournal of combinatorial designs (Print), 2018
Commonly, the direct construction and the description of mutually orthogonal Latin squares (MOLS) make use of difference or quasi‐difference matrices. Now there exists a correspondence between MOLS and separable permutation codes.

More mutually orthogonal latin squares

open access: yesDiscrete Mathematics, 1982
AbstractWilson's construction for mutually orthogonal Latin squares is generalized. This generalized construction is used to improve known bounds on the function nr (the largest order for which there do not exist r MOLS). In particular we find n7⩽780, n8⩽4738, n9⩽5842, n10⩽7222, n11⩽7478, n12⩽9286, n13⩽9476, n15⩽10632.

Three-way cross designs for animal breeding experiments

open access: yesIndian Journal of Animal Sciences, 2016
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.

Mutually Orthogonal Latin Squares and Self-complementary Designs [PDF]

open access: yes, 2006
Suppose that n is even and a set of n/2 -1 mutually orthogonal Latin squares of order n exists. Then we can construct a strongly regular graph with parameters (n², n/2 (n-1), n/2 ( n/2-1), n/2 ( n/2 -1)), which is called a Latin square graph.

Solution to the Mean King's problem with mutually unbiased bases for arbitrary levels [PDF]

open access: yes, 2006
The Mean King's problem with mutually unbiased bases is reconsidered for arbitrary d-level systems. Hayashi, Horibe and Hashimoto [Phys. Rev. A 71, 052331 (2005)] related the problem to the existence of a maximal set of d-1 mutually orthogonal Latin ...
