On island sequences of labelings with a condition at distance two
TLDR
An L(2,1)-labeling of a graph G, first studied by Griggs and Yeh in 1992 [10], is a function f from the vertex set of G to the set of nonnegative integers such that |f (x) − f (y)|>=2 if d(x,y)=1, and |f(x)-f(y) denotes the distance between the pair of vertices x,y. Expand

Modeling the spread of fault in majority-based network systems: Dynamic monopolies in triangular grids
TLDR
A graph theoretical model of the spread of fault in distributed computing and communication networks, each element in the network is represented by a vertex of a graph where edges connect pairs of communicating elements, and each colored vertex corresponds to a faulty element at discrete time periods.

Dynamic monopolies and feedback vertex sets in hexagonal grids
TLDR
This paper establishes a connection between dynamic monopolies and feedback vertex sets which are sets of vertices whose removal results in an acyclic graph. Expand

The Final Case of the Decoding Delay Problem for Maximum Rate Complex Orthogonal Designs
TLDR
In this paper, the final case is addressed, and it is shown that when the number of columns is congruent to 2 modulo 4, the lower bound on decoding delay cannot be achieved. Expand

Multilevel and multidimensional Hadamard matrices
TLDR
Multilevel Hadamard matrices, whose entries are integers as opposed to the traditional restriction to {±1}, were introduced by Trinh, Fan, and Gabidulin in 2006 as a way to construct multilevel zero-correlation zone sequences, which have been studied for use in approximately synchronized code division multiple access systems.

On the issue of decoupled decoding of codes derived from quaternion orthogonal designs
Quaternion orthogonal designs (QODs) have been previously introduced as a basis for orthogonal space-time polarization block codes (OSTPBCs). This note will serve to correct statements concerning theExpand
