A note on the metric and edge metric dimensions of 2-connected graphs [PDF]

open access: yes, 2021
For a given graph G, the metric and edge metric dimensions of G, dim(G) and edim(G), are the cardinalities of the smallest possible subsets of vertices in V(G) such that they uniquely identify the vertices and the edges of G, respectively, by means of ...

Machine-Vision-Based Algorithm for Blockage Recognition of Jittering Sieve in Corn Harvester

open access: yesApplied Sciences, 2020
Jittering sieve is a significant component of corn harvester, and it is used to separate kernels from impurities. The sieves may be blocked by kernels during the separating process, leading to the reduction of working performance.

On Resolvability Parameters of Some Wheel-Related Graphs

open access: yesJournal of Chemistry, 2019
Let G=V,E be a simple connected graph, w∈V be a vertex, and e=uv∈E be an edge. The distance between the vertex w and edge e is given by de,w=mindw,u,dw,v, A vertex w distinguishes two edges e1, e2∈E if dw,e1≠dw,e2.

On determining the weight of edges in map-representing graphs-applications of heuristic methods in planning escape routes

open access: yesJournal of Traffic and Transportation Engineering (English ed. Online), 2022
In the paper we discuss and compare two commonly used methods of finding the shortest paths in networks, namely Dijkstra's and A∗ algorithms. We compare their effectiveness in terms of traversing road network in circumstances that require swift decision ...

Diffusion histology imaging differentiates distinct pediatric brain tumor histology

open access: yesScientific Reports, 2021
High-grade pediatric brain tumors exhibit the highest cancer mortality rates in children. While conventional MRI has been widely adopted for examining pediatric high-grade brain tumors clinically, accurate neuroimaging detection and differentiation of ...
