L(2, 1)-Labelings of Some Families of Oriented Planar Graphs
In this paper we determine, or give lower and upper bounds on, the 2-dipath and oriented L(2, 1)-span of the family of planar graphs, planar graphs with girth 5, 11, 16, partial k-trees, outerplanar graphs and cacti.

Low Density Parity Check Codes Constructed from Hankel Matrices
In this paper, a new technique for constructing low density parity check codes based on the Hankel matrix and circulant permutation matrices is proposed. The new codes are exempt of any cycle of length 4.

On Regular Hypergraphs of High Girth [PDF]
We give lower bounds on the maximum possible girth of an $r$-uniform, $d$-regular hypergraph with at most $n$ vertices, using the definition of a hypergraph cycle due to Berge. These differ from the trivial upper bound by an absolute constant factor (viz., by a factor of between $3/2+o(1)$ and $2 +o(1)$).

Light Graphs In Planar Graphs Of Large Girth
A graph H is defined to be light in a graph family 𝒢 if there exist finite numbers φ(H, 𝒢) and w(H, 𝒢) such that each G ∈ 𝒢 which contains H as a subgraph, also contains its isomorphic copy K with ΔG(K) ≤ φ(H, 𝒢) and ∑x∈V(K) degG(x) ≤ w(H, 𝒢).

Scan posture definition and hip girth measurement: the impact on clothing design and body scanning
Ergonomic measurement is central to product design and development; especially for body worn products and clothing. However, there is a large variation in measurement definitions, complicated by new body scanning technology that captures measurements in ...

The Relationship Between Stature and Live Weight of Dairy Cows Between Birth and Maturity
Lactational and reproductive performance are strongly associated with cow live weight and capacity. However, there are limited data published describing capacity (thoracic) growth and the prediction of final stature and capacity from measurements at ...

On the girth of Tanner (3,7) quasi-cyclic LDPC codes [PDF]
S. Kim, et al, have been analyzed the girth of some algebraically structured quasi-cyclic (QC) low-density parity-check (LDPC) codes, i.e. Tanner (3,5) of length 5p, where p is a prime of the form 15m+1. In this paper, by extension this method to Tanner (

Abelian girth and gapped sheaves [PDF]
The girth of a graph is the length of the shortest cycle in a graph, and the abelian girth of a graph is the girth of the graph's universal abelian covering graph. We denote the abelian girth of a graph G as Abl(G) and show that for d-regular graphs on n

Note on the girth of Ramanujan graphs [PDF]
The purpose of this note is to establish an upper bound for the girth of the Ramanujan graphs constructed by Lubozky, Phillips, and Sarnak, thereby determining the asymptotic behaviour of the girth of these ...

Super-reflexivity and the girth of spheres [PDF]
It is shown that a Banach space is super-reflexive if and only if the girth of its unit ball is greater than 4. Consequently, "girth greater than 4" is a property preserved under isomorphisms and duality.
