Sharp Bounds on (Generalized) Distance Energy of Graphs

open access: yesMathematics, 2020
Given a simple connected graph G, let D ( G ) be the distance matrix, D L ( G ) be the distance Laplacian matrix, D Q ( G ) be the distance signless Laplacian matrix, and T r ( G ) be the vertex transmission ...

The Generalized Distance Spectrum of the Join of Graphs [PDF]

open access: yes, 2020
Let G be a simple connected graph. In this paper, we study the spectral properties of the generalized distance matrix of graphs, the convex combination of the symmetric distance matrix D(G) and diagonal matrix of the vertex transmissions Tr(G) .

On Computation and Analysis of Topological Index-Based Invariants for Complex Coronoid Systems

open access: yesComplexity, 2021
In chemical graph theory, benzenoid systems are interrogated as they exhibit the chemical compounds known as benzenoid hydrocarbons. Benzenoid schemes are circumscribed as planar connected finite graphs having no cut vertices wherein the entire internal ...

An analysis of the lifetime of OLSR networks [PDF]

open access: yes, 2009
The Optimized Link State Routing (OLSR) protocol is a well-known route discovery protocol for ad-hoc networks. OLSR optimizes the flooding of link state information through the network using multipoint relays (MPRs).

Efficient qualitative risk assessment of pipelines using relative risk score based on machine learning

open access: yesScientific Reports, 2023
Pipelines are observed one of the economic modes of transport for transporting oil, gas, and water between various locations. Most of the countries in the world transport petroleum and other flammable products through underground pipelines.

On the distance α-spectral radius of a connected graph

open access: yesJournal of Inequalities and Applications, 2020
For a connected graph G and α ∈ [ 0 , 1 ) $\alpha \in [0,1)$ , the distance α-spectral radius of G is the spectral radius of the matrix D α ( G ) $D_{\alpha }(G)$ defined as D α ( G ) = α T ( G ) + ( 1 − α ) D ( G ) $D_{\alpha }(G)=\alpha T(G)+(1-\alpha )

Rotation-based schedules in elementary schools to prevent COVID-19 spread: a simulation study

open access: yesScientific Reports, 2023
Rotations of schoolchildren were considered as a non-pharmacological intervention in the COVID-19 pandemic. This study investigates the impact of different rotation and testing schedules.We built an agent-based model of interactions among pupils and ...

Content Based Status Updates [PDF]

open access: yes, 2018
Consider a stream of status updates generated by a source, where each update is of one of two types: high priority or ordinary (low priority). These updates are to be transmitted through a network to a monitor.

Modeling epidemics on a regular tree graph

open access: yesLetters in Biomathematics, 2016
We will first provide a brief introduction to models of disease transmission on so-called contact networks, which can be represented by various structures from the mathematical field of graph theory.
