On Minimum Maximal Distance-k Matchings [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2018
We study the computational complexity of several problems connected with finding a maximal distance-$k$ matching of minimum cardinality or minimum weight in a given graph. We introduce the class of $k$-equimatchable graphs which is an edge analogue of $k$

The minimum distance problem for two-way entanglement purification [PDF]

open access: green, 2006
Entanglement purification takes a number of noisy EPR pairs and processes them to produce a smaller number of more reliable pairs. If this is done with only a forward classical side channel, the procedure is equivalent to using a quantum error-correcting

Combining distance and anatomical information for deep-learning based dose distribution predictions for nasopharyngeal cancer radiotherapy planning

open access: yesFrontiers in Oncology, 2023
PurposeDeep-learning effectively predicts dose distributions in knowledge-based radiotherapy planning. Using anatomical information that includes a structure map and computed tomography (CT) data as input has been proven to work well.

DEGREE DISTANCE AND MINIMUM DEGREE [PDF]

open access: yesBulletin of the Australian Mathematical Society, 2012
AbstractLet G be a finite connected graph of order n, minimum degree δ and diameter d. The degree distance D′(G) of G is defined as ∑ {u,v}⊆V (G)(deg u+deg v) d(u,v), where deg w is the degree of vertex w and d(u,v) denotes the distance between u and v. In this paper, we find an asymptotically sharp upper bound on the degree distance in terms of order,

Lengths for Which Fourth Degree PP Interleavers Lead to Weaker Performances Compared to Quadratic and Cubic PP Interleavers

open access: yesEntropy, 2020
In this paper, we obtain upper bounds on the minimum distance for turbo codes using fourth degree permutation polynomial (4-PP) interleavers of a specific interleaver length and classical turbo codes of nominal 1/3 coding rate, with two recursive ...

The minimum miss distance problem [PDF]

open access: yesProceedings of the American Mathematical Society, 1967
I. In the statement of most extant theorems concerning optimal control, a fundamental hypothesis is that of the existence of a control function which drives the controlled system from a given initial state to a specified target. Thus the utility of these theorems is contingent upon the solution of what is itself a fundamental and difficult problem of ...

Minimum local distance density estimation [PDF]

open access: yesCommunications in Statistics - Theory and Methods, 2016
We present a local density estimator based on first order statistics. To estimate the density at a point, $x$, the original sample is divided into subsets and the average minimum sample distance to $x$ over all such subsets is used to define the density estimate at $x$. The tuning parameter is thus the number of subsets instead of the typical bandwidth

Minimum orbital intersection distance: an asymptotic approach [PDF]

open access: yesAstronomy & Astrophysics, 2019
The minimum orbital intersection distance (MOID) is used as a measure to assess potential close approaches and collision risks between astronomical objects. Methods to calculate this quantity have been proposed in several previous publications. The most frequent case is that in which both objects have elliptical osculating orbits.

Lattice polytopes in coding theory [PDF]

open access: yes, 2014
In this paper we discuss combinatorial questions about lattice polytopes motivated by recent results on minimum distance estimation for toric codes. We also prove a new inductive bound for the minimum distance of generalized toric codes.
