Source location on multilayer networks [article]

Robert Paluch, Łukasz G. Gajewski, K. Suchecki, Janusz A. Hołyst
2020 arXiv   pre-print
Nowadays it is not uncommon to have to deal with dissemination on multi-layered networks and often finding the source of said propagation can be a crucial task.  ...  In this paper we tackle this exact problem with a maximum likelihood approach that we extend to be operational on multi-layered graphs.  ...  The model is adapted to multi-layer networks, therefore the intra-layer infection rate has a form of vector β = [β 1 , β 2 , . . . , β l ].  ...

Blockchain-Envisioned Softwarized Multi-Swarming UAVs to Tackle COVID-I9 Situations

Rajesh Gupta, Aparna Kumari, Sudeep Tanwar, Neeraj Kumar
2020 IEEE Network  
This enabled UAVs to communicate with each other through a directed short-range communication channel in the infected region and share real-time data of resident locations with high precision (i.e., geo-location  ...  A single UAV swarming network can cover only one single geographic location. But to monitor multiple geographic locations simultaneously, there is a need for a multi-swarming UAV network.  ...

2017 PROCEEDINGS OF THE THIRTIETH AAAI CONFERENCE ON ARTIFICIAL INTELLIGENCE AND THE TWENTY-EIGHTH INNOVATIVE APPLICATIONS OF ARTIFICIAL INTELLIGENCE CONFERENCE  
This paper studies the problem of locating multiple diffusion sources in networks with partial observations. We propose a new source localization algorithm, named Optimal-Jordan-Cover (OJC).  ...  Considering the heterogeneous susceptible-infected-recovered (SIR) diffusion in the Erdos-Renyi (ER) random graph, we prove that OJC can locate all sources with probability one asymptotically with partial  ...  Acknowledgments This work was supported in part by the U.S. Army Research Laboratory's Army Research Office (ARO Grant No.  ...

An Agent-Based Modeling for Pandemic Influenza in Egypt [article]

Khaled M. Khalil, M. Abdel-Aziz, Taymour T. Nazmy, Abdel-Badeeh M. Salem
2010 arXiv   pre-print
The proposed multi-agent model is based on the modeling of individuals' interactions in a space time context.  ...  The proposed model involves different types of parameters such as: social agent attributes, distribution of Egypt population, and patterns of agents' interactions.  ...  Infected agent will affect all agents in his social networks to be exposed. Thus, probability of agent to be infected increases according to the number of infected agents in his social networks.  ...

Smart Testing with Vaccination: A Bandit Algorithm for Active Sampling for Managing COVID-19 [article]

Yingfei Wang, Inbal Yahav, Balaji Padmanabhan
2021 medRxiv   pre-print
The results show that smart-testing is effective in significantly reducing infection and death rates as compared to current policies, with or without vaccination.  ...  Using a data-driven agent-based model simulating New York City we show that the algorithm samples individuals to test in a manner that rapidly traces infected individuals.  ...  For instance, with low vaccination rate and high compliance, the percentage infected drops by ∼ 45%. • Asymptomatic transmission is a significant aspect of Covid-19.  ...
