Realizing Optimal All-to-All Personalized Communication Using Butterfly-Based Networks

open access: yesIEEE Access, 2023
The communication network is a key component in parallel and distributed systems, high-performance computing (HPC) systems and Data Centers, as information exchange has a key role in communication-intensive applications.

Interference Alignment Schemes Using Latin Square for K $\times$ 3 MIMO X Channel

open access: yesIEEE Access, 2019
In this paper, we study an interference alignment (IA) scheme with finite time extension and beamformer selection method with low computational complexity for X channel. An IA scheme with a chain structure by the Latin square is proposed for $K \times 3$

Anti-Ramsey theory on complete bipartite graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
We consider quadruples of positive integers with and such that every proper edge-coloring of the complete bipartite graph contains a rainbow subgraph. We show that every such quadruple with and satisfies this property and find an infinite sequence where ...

Mathematics: What’s Spatial, What’s Not

open access: yesQuaestiones Geographicae, 2015
Probably, almost everyone has some idea of what is meant by the words ‘spatial mathematics.’ The problem is that 100 people have 100 different ideas, because the concept is not easy to codify. In this paper we suggest a few ways to illustrate differences

A Hybrid Cryptosystem based on Latin Square and the Modified BB84 Quantum Key Distribution

open access: yesTikrit Journal of Pure Science, 2022
A new algorithm to improve the security of the transmitted data over the communication channels is presented in this paper. This algorithm is combining Latin square with the modified version of the BB84 Quantum Key Distribution protocol. As the order of

Applications of design theory for the constructions of MDS matrices for lightweight cryptography

open access: yesJournal of Mathematical Cryptology, 2017
In this paper, we observe simple yet subtle interconnections among design theory, coding theory and cryptography. Maximum distance separable (MDS) matrices have applications not only in coding theory but are also of great importance in the design of ...

Construction of a repetitive magic square with Ramanujan's number as its product

open access: yesHeliyon, 2023
In this article, we build a repetitive magic square by multiplying four elements. This square is a matrix with its corresponding elements. The elements of this matrix that take different values allow us to obtain Ramanujan's number 1729 as its ...

Constructing Mutually Unbiased Bases from Quantum Latin Squares [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2017
We introduce orthogonal quantum Latin squares, which restrict to traditional orthogonal Latin squares, and investigate their application in quantum information science.
