Fault-tolerant metric dimension of zero-divisor graphs of commutative rings

open access: yesAKCE International Journal of Graphs and Combinatorics, 2021
Let R be a commutative ring with identity. The zero-divisor graph of R denoted by is an undirected graph where is the set of non-zero zero-divisors of R and there is an edge between the vertices z1 and z2 in if A set of vertices S resolves a graph G if ...

Edge Metric Dimension and Edge Basis of One-Heptagonal Carbon Nanocone Networks

open access: yesIEEE Access, 2022
A molecular (chemical) graph is a simple connected graph, where the vertices represent the compound’s atoms and the edges represent bonds between the atoms, and the degree (valence) of every vertex (atom) is not more than four.

The dominant metric dimension of graphs

open access: yesHeliyon, 2020
The G be a connected graph with vertex set V(G) and edge set E(G). A subset S⊆V(G) is called a dominating set of G if for every vertex x in V(G)∖S, there exists at least one vertex u in S such that x is adjacent to u.

Fractional Metric Dimension of Generalized Sunlet Networks

open access: yesJournal of Mathematics, 2021

Edge-disjoint cycles with the same vertex set [PDF]

open access: yesAdvances in Mathematics
In 1975, Erd\H{o}s asked for the maximum number of edges that an $n$-vertex graph can have if it does not contain two edge-disjoint cycles on the same vertex set. It is known that Tur\'an-type results can be used to prove an upper bound of $n^{3/2+o(1)}$.

Computing the partition dimension of certain families of Toeplitz graph

open access: yesFrontiers in Computational Neuroscience, 2022
Let G = (V(G), E(G)) be a graph with no loops, numerous edges, and only one component, which is made up of the vertex set V(G) and the edge set E(G). The distance d(u, v) between two vertices u, v that belong to the vertex set of H is the shortest path ...

A Reconfigurable energy-resolving method for a layered edge-on detector

open access: yesPhysics in Medicine and Biology, 2019
Currently, most of the x-ray spectral detectors can extract signals in a set number of energy bins, that inevitably reduces the dynamic range and energy resolution of the imaging system.

Resolving sets of vertices with the minimum size in graphs [PDF]

open access: yesریاضی و جامعه, 2023
Suppose that $G$ is a simple connected graph with vertex set $V(G)$ and edge set $E(G)$. A subset $S=\{s_1, s_2,\ldots , s_l \}$ of vertices of graph $G$ is called a doubly resolving set of $G$, if for any distinct vertices $u$ and $v$ in $G$ there are ...

On resolving efficient domination number of path and comb product of special graph

open access: yesJournal of Physics, Conference Series, 2022
We use finite, connected, and undirected graph denoted by G. Let V (G) and E(G) be a vertex set and edge set respectively. A subset D of V (G) is an efficient dominating set of graph G if each vertex in G is either in D or adjoining to a vertex in D.

Establishing and using a genetic database for resolving identification of fish species in the Sea of Galilee, Israel

open access: yesPLoS ONE, 2022
Freshwaters are a very valuable resource in arid areas, such as Mediterranean countries. Freshwater systems are vulnerable ecological habitats, significantly disturbed globally and especially in arid areas.
