Pre-emptive spectral graph protection strategies on multiplex social networks [PDF]

open access: yesApplied Network Science, 2018
Constructing effective and scalable protection strategies over epidemic propagation is a challenging issue. It has been attracting interests in both theoretical and empirical studies. However, most of the recent developments are limited to the simplified

TEE-Graph: efficient privacy and ownership protection for cloud-based graph spectral analysis

open access: yesFrontiers in Big Data, 2023
IntroductionBig graphs like social network user interactions and customer rating matrices require significant computing resources to maintain. Data owners are now using public cloud resources for storage and computing elasticity.

A quality evaluation method for the unstructured defect record of relay protection devices based on ontology and knowledge graph

open access: yesEnergy Reports, 2023
The original unstructured record data for the defect of the relay protection devices (RPDs) may contain problems influencing the data mining, and it is lack of quantitative evaluation.

A method for eternally dominating strong grids [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
In the eternal domination game, an attacker attacks a vertex at each turn and a team of guards must move a guard to the attacked vertex to defend it. The guards may only move to adjacent vertices and no more than one guard may occupy a vertex.

Eternal domination and clique covering

open access: yesElectronic Journal of Graph Theory and Applications, 2022
We study the relationship between the eternal domination number of a graph and its clique cove-ring number using both large-scale computation and analytic methods. In doing so, we answer two open questions of Klostermeyer and Mynhardt.

Protection Strategy against an Epidemic Disease on Edge-Weighted Graphs Applied to a COVID-19 Case

open access: yesBiology, 2021
Among the diverse and important applications that networks currently have is the modeling of infectious diseases. Immunization, or the process of protecting nodes in the network, plays a key role in stopping diseases from spreading.

A novel fault diagnosis method for power grid based on graph Fourier transform

open access: yesFrontiers in Energy Research, 2023
The fast and robust identification of fault elements is essential for the security and continuous operation of the power grid. The existing methods might be maloperation for bad data disturbance and require strict and exact synchronization.
