Land Cover and Crop Classification Based on Red Edge Indices Features of GF-6 WFV Time Series Data

open access: yesRemote Sensing, 2021
Time series of vegetation indices can be utilized to capture crop phenology information, and have been widely used in land cover and crop classification, phenological feature extraction, and planting structure monitoring.

Belief propagation for optimal edge cover in the random complete graph [PDF]

open access: yesarXiv.org, 2014
We apply the objective method of Aldous to the problem of finding the minimum-cost edge cover of the complete graph with random independent and identically distributed edge costs.

New Bounds for Edge-Cover by Random Walk [PDF]

open access: yesCombinatorics, probability & computing, 2011
We show that the expected time for a random walk on a (multi-)graph $G$ to traverse all $m$ edges of $G$, and return to its starting point, is at most $2m^2$; if each edge must be traversed in both directions, the bound is $3m^2$.

An Approximation Algorithm for Two-Edge-Connected Subgraph Problem via Triangle-Free Two-Edge-Cover [PDF]

open access: greenInternational Symposium on Algorithms and Computation, 2023
The $2$-Edge-Connected Spanning Subgraph problem (2-ECSS) is one of the most fundamental and well-studied problems in the context of network design. In the problem, we are given an undirected graph $G$, and the objective is to find a $2$-edge-connected ...

Strong Edge Cover of the Graph

open access: diamond, 2017
The degree of a vertex v (denoted by deg(v)) is equal to the number of vertices that are adjacent to v. If there is a vertex v ∈ V(G) such that deg(v) = 0 then v is called an isolated vertex. If deg(v) = 1 then v is called a pendent vertex.

Fast Sampling of $b$-Matchings and $b$-Edge Covers [PDF]

open access: greenACM-SIAM Symposium on Discrete Algorithms, 2023
For an integer $b \ge 1$, a $b$-matching (resp. $b$-edge cover) of a graph $G=(V,E)$ is a subset $S\subseteq E$ of edges such that every vertex is incident with at most (resp. at least) $b$ edges from $S$.

Edge Cover Through Edge Coloring [PDF]

open access: diamondElectronic Journal of Combinatorics
Let $G$ be a multigraph. A subset $F$ of $E(G)$ is an edge cover of $G$ if every vertex of $G$ is incident to an edge of $F$. The cover index, $\xi(G)$, is the largest number of edge covers into which the edges of $G$ can be partitioned. Clearly $\xi(G) \

Weighted Upper Edge Cover: Complexity and Approximability [PDF]

open access: yesWorkshop on Algorithms and Computation, 2018
Optimization problems consist of either maximizing or minimizing an objective function. Instead of looking for a maximum solution (resp. minimum solution), one can find a minimum maximal solution (resp. maximum minimal solution).

On the Complexity of the Upper r-Tolerant Edge Cover Problem

open access: yesInternational Conference on Topics in Theoretical Computer Science, 2020
. We consider the problem of computing edge covers that are tolerant to a certain number of edge deletions. We call the problem of finding a minimum such cover r -Tolerant Edge Cover ( r -EC) and the problem of finding a maximum minimal such cover Upper r -

X-ray absorption spectroscopy and X-ray diffraction data for molybdenum minerals and compounds

open access: yesData in Brief, 2022
We report Mo K- and LIII-edge X-ray absorption spectroscopy (XAS) and X-ray diffraction (XRD) data collected for 15 molybdenum minerals and compounds sourced from museum collections, mineral dealers, and chemical suppliers. The samples were finely ground
