Cohorting to isolate asymptomatic spreaders: An agent-based simulation study on the Mumbai Suburban Railway
Alok Talekar, Sharad Shriram, Nidhin Vaidhiyan +10
The Mumbai Suburban Railways, \emph{locals}, are a key transit infrastructure of the city and is crucial for resuming normal economic activity. To reduce disease transmission, poli…
COVID-19: Optimal Design of Serosurveys for Disease Burden Estimation
Siva Athreya, Giridhara R. Babu, Aniruddha Iyer +6
We provide a methodology by which an epidemiologist may arrive at an optimal design for a survey whose goal is to estimate the disease burden in a population. For serosurveys with…
A Distributed Hierarchy Framework for Enhancing Cyber Security of Control Center Applications
Chetan Kumar Kuraganti, Bryan Paul Robert, Gurunath Gurrala +4
Recent cyber-attacks on power grids highlight the necessity to protect the critical functionalities of a control center vital for the safe operation of a grid. Even in a distribute…
City-Scale Agent-Based Simulators for the Study of Non-Pharmaceutical Interventions in the Context of the COVID-19 Epidemic
Shubhada Agrawal, Siddharth Bhandari, Anirban Bhattacharjee +14
We highlight the usefulness of city-scale agent-based simulators in studying various non-pharmaceutical interventions to manage an evolving pandemic. We ground our studies in the c…
Large deviations of mean-field interacting particle systems in a fast varying environment
Sarath Yasodharan, Rajesh Sundaresan
This paper studies large deviations of a ``fully coupled" finite state mean-field interacting particle system in a fast varying environment. The empirical measure of the particles…
Sequential Multi-hypothesis Testing in Multi-armed Bandit Problems:An Approach for Asymptotic Optimality
Gayathri R Prabhu, Srikrishna Bhashyam, Aditya Gopalan +1
We consider a multi-hypothesis testing problem involving a K-armed bandit. Each arm's signal follows a distribution from a vector exponential family. The actual parameters of the a…
COVID-19 Epidemic Study II: Phased Emergence From the Lockdown in Mumbai
Prahladh Harsha, Sandeep Juneja, Preetam Patil +7
The nation-wide lockdown starting 25 March 2020, aimed at suppressing the spread of the COVID-19 disease, was extended until 31 May 2020 in three subsequent orders by the Governmen…
Detecting an Odd Restless Markov Arm with a Trembling Hand
P. N. Karthik, Rajesh Sundaresan
In this paper, we consider a multi-armed bandit in which each arm is a Markov process evolving on a finite state space. The state space is common across the arms, and the arms are…
The Erlang Weighted Tree, A New Branching Process
Mehrdad Moharrami, Vijay Subramanian, Mingyan Liu +1
In this paper, we study a new discrete tree and the resulting branching process, which we call the \textbf{E}rlang \textbf{W}eighted \textbf{T}ree(\textbf{EWT}). The EWT appears as…
