Data Allocation Algorithm for Large Data with All-to-all Comparison Based on Graph Covering [PDF]
In the process of distributed processing of all-to-all comparison problem for large data,the existing data allocation strategies think less of the special dependency between the comparison task and the data,which lead to the low storage efficiency and ...

We study problems that arise in the context of covering certain geometric objects called seeds (e.g., points or disks) by a set of other geometric objects called cover (e.g., a set of disks or homothetic triangles). We insist that the interiors of the seeds and the cover elements are pairwise disjoint, respectively, but they can touch.

Extensions to emergency vehicle location models [PDF]
This paper is concerned with extending models for the Maximal Covering Location Problem in two ways. First, the usual 0-1 coverage definition is replaced by the probability of covering a demand within the target time.

Graph labelling is a function that maps graph elements to positive integers. A covering of graph is family subgraph from , for with integer k. Graph admits covering if for every subgraph is isomorphic to a graph .

Some inequalities involving the distance signless Laplacian eigenvalues of graphs [PDF]
Given a simple graph $G$, the distance signlesss Laplacian $D^{Q}(G)=Tr(G)+D(G)$ is the sum of vertex transmissions matrix $Tr(G)$ and distance matrix $D(G)$.

A covering projection from a graph \(G\) onto a graph \(H\) is a ``local isomorphism'': a mapping from the vertex set of \(G\) onto the vertex set of \(H\) such that, for every \(v\in V(G)\), the neighborhood of \(v\) is mapped bijectively onto the neighborhood (in \(H\)) of the image of \(v\).

Homotopy Covers of Graphs and Lifting Property
The aim of this paper We create requirements for a graph cover to have the homotopy lifting property of topological space covers, or A-Homotopy lifting property.

Exact information ratios for secret sharing on small graphs with girth at least 5
In a secret-sharing scheme, a piece of information – the secret – is distributed among a finite set of participants in such a way that only some predefined coalitions can recover it.

Coverability of Graphs by Parity Regular Subgraphs
A graph is even (resp. odd) if all its vertex degrees are even (resp. odd). We consider edge coverings by prescribed number of even and/or odd subgraphs.
