On Near Mean Graphs [PDF]

open access: yes, 2010
A graph that admits a Smarandachely near mean m-labeling is called Smarandachely near m-mean graph. The graph that admits a near mean labeling is called a near mean graph (NMG)

The Effect of Structure Building Small Mammals in a Shifting Arctic Landscape

open access: yesEcology and Evolution
Landscapes are undergoing ecological changes, and how organisms interact with changing habitats has implications for zoogeochemical influences on ecosystem function (processes and properties). This may be especially true for organisms that alter nutrient

Home range and habitat use of roe deer (<em>Capreolus capreolus</em>) reared in captivity and released in the wild

open access: yesHystrix, the Italian Journal of Mammalogy, 1997
<strong>Abstract</strong> In autumn 1992 two subadult males, reared in captivity, were radio-tagged and released on the northern slopes of Monte Carso near the city of Trieste. The annual mean size of the home range resulted to be 38.5 ha by

Homogeneous Graphs and Regular Near Polygons

open access: yesJournal of Combinatorial Theory, Series B, 1994
A homogeneous graph \(\Gamma\) is defined: for every edge \(uv\), and vertex \(x\), the number of edges from \(x\) to \(\Gamma_ i(u)\cap\Gamma_ j(v)\) depends only on \(i\), \(j\) and the distances from \(x\) to \(u\) and \(v\). (\(\Gamma_ i(u)\) is the set of vertices of distance \(i\) from \(u\).) It is proven that, for distance-regular graphs in ...

A Higman-Haemers Inequality for Thick Regular Near Polygons [PDF]

open access: yesJournal of Algebraic Combinatorics, 2004
Let \(\Gamma\) be a generalized \(n\)-gon of order \((s, t)\) (i.e. on every line there are exactly \(s+1\) points and every point lies on \(t+1\) lines). W. Feit and D. G. Higman showed that, apart from the ordinary polygons, finite examples only exist for \(n = 3, 4, 6, 8\) or \(12\). If \(s>1\) and \(t>1\), then \(n = 12\) is not possible.

Computing Maximum Polygonal Packings in Convex Polygons using Best-Fit, Genetic Algorithms and Integer Linear Programs

open access: yesComputing in Geometry and Topology
Given a convex region \(C\) and a set of simple polygons with associated profits, the Maximum Polygon Packing Problem seeks a non-overlapping packing of a subset of the polygons (without rotations) into \(C\), such that the total profit of the packed ...

The valuations of the near polygon G\(_{n}\)

open access: yesElectron. J. Comb., 2009
The author classifies the valuations of the near polygon \(\mathbb{G}_n\). A \textit{near polygon} is a point-line incidence geometry such that two points determine at most one line, and for each point \(p\) and line \(L\), there is a unique point on \(L\) nearest to \(p\) in the point collinearity graph.

The Universal Embedding of the Near Polygon ${\Bbb G}_n$ [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2007
In an earlier paper, we showed that the dual polar space $DH(2n-1,4)$, $n \geq 2$, has a sub near-$2n$-gon ${\Bbb G}_n$ with a large automorphism group. In this paper, we determine the absolutely universal embedding of this near polygon. We show that the generating and embedding ranks of ${\Bbb G}_n$ are equal to ${2n \choose n}$. We also show that the

Smarandache near-rings [PDF]

open access: yes, 2002
The main concern of this book is the study of Smarandache analogue properties of near-rings and Smarandache near-rings; so it does not promise to cover all concepts or the proofs of all ...
