Discovering Irregularities from Computer Networks by Topological Mapping
Applied Sciences, 2022 Any number that can be uniquely identified and varied by a graph is known as a graph invariant. This paper will talk about three unique variations of bridge networks, sierpinski networks, honeycomb, and hexagonal networks, with great capability of ...

Product irregularity strength of certain graphs
Ars Mathematica Contemporanea, 2013 Consider a simple graph G with no isolated edges and at most one isolated vertex. A labeling w : E ( G ) → {1, 2, …, m } is called product - irregular , if all product degrees p d G ( v ) = ∏ e ∋ v w ( e ) are distinct. The goal is to obtain a product - irregular labeling that minimizes the maximal label.

Principal eigenvectors of irregular graphs
The Electronic Journal of Linear Algebra, 2007 Let G be a connected graph. Thispaper s extreme entriesof the principal eigenvector x of G, the unique positive unit eigenvector corresponding to the greatest eigenvalue λ1 of the adjacency matrix of G.I fG hasmaximum degree ∆, the greates t entry xmax of x isat mos t 1/ 1+ λ 2 /∆. This improves a result of Papendieck and Recht. The least entry xmin of

Surface Tension Measurement of Ti‐6Al‐4V by Falling Droplet Method in Oxygen‐Free Atmosphere
Advanced Engineering Materials, EarlyView.In this article, the temperature‐dependent surface tension of free falling, oscillating Ti‐6Al‐4V droplets is investigated in both argon and monosilane doped, oxygen‐free atmosphere. Droplet temperature and oscillation are captured with one single high‐speed camera, and the surface tension is calculated with Rayleigh's formula.
