Absolutely Maximally Entangled states, combinatorial designs and multi-unitary matrices [PDF]

, 2015
Absolutely Maximally Entangled (AME) states are those multipartite quantum states that carry absolute maximum entanglement in all possible partitions. AME states are known to play a relevant role in multipartite teleportation, in quantum secret sharing ...

Exotic complex Hadamard matrices, and their equivalence [PDF]

, 2010
In this paper we use a design theoretical approach to construct new, previously unknown complex Hadamard matrices. Our methods generalize and extend the earlier results of de la Harpe--Jones and Munemasa--Watatani and offer a theoretical explanation for ...

Engineering failure analysis and design optimisation with HiP-HOPS [PDF]

, 2010
The scale and complexity of computer-based safety critical systems, like those used in the transport and manufacturing industries, pose significant challenges for failure analysis. Over the last decade, research has focused on automating this task.

R.A.Fisher, design theory, and the Indian connection [PDF]

, 2009
Design Theory, a branch of mathematics, was born out of the experimental statistics research of the population geneticist R. A. Fisher and of Indian mathematical statisticians in the 1930s.

Block Design-Based Asynchronous Neighbor Discovery Protocol for Wireless Sensor Networks

J. Sensors, 2015
Neighbor discovery is a significant research topic in wireless sensor networks. After wireless sensor devices are deployed in specific areas, they attempt to determine neighbors within their communication range.

Combinatorics in the Art of the Twentieth Century [PDF]

, 2017
This paper is motivated by a question I asked myself: How can combinatorial structures be used in a work of art? Immediately, other questions arose: Whether there are artists that work or think combinatorially?

Generalized covering designs and clique coverings

, 2011
Inspired by the "generalized t-designs" defined by Cameron [P. J. Cameron, A generalisation of t-designs, Discrete Math. 309 (2009), 4835--4842], we define a new class of combinatorial designs which simultaneously provide a generalization of both ...

Problems on q-Analogs in Coding Theory [PDF]

, 2013
The interest in $q$-analogs of codes and designs has been increased in the last few years as a consequence of their new application in error-correction for random network coding. There are many interesting theoretical, algebraic, and combinatorial coding
