Delay-Induced Watermarking for Detection of Replay Attacks in Linear Systems
Christoforos Somarakis, Raman Goyal, Erfaun Noorani +1
A state-feedback watermarking signal design for the detection of replay attacks in linear systems is proposed. The control input is augmented with a random time-delayed term of the…
Cascading Waves of Fluctuation in Time-delay Multi-agent Rendezvous
Guangyi Liu, Vivek Pandey, Christoforos Somarakis +1
We develop a framework to assess the risk of cascading failures when a team of agents aims to rendezvous in time in the presence of exogenous noise and communication time-delay. Th…
Physics-Based Nozzle Design Rules for High-Frequency Liquid Metal Jetting
Jongmin Seo, Christoforos Somarakis, Svyatoslav Korneev +2
We present physics-based nozzle design rules to achieve high-throughput and stable jetting in drop-on-demand liquid metal 3D printing. The design rules are based on scaling laws th…
Risk of Phase Incoherence in Wide Area Control of Synchronous Power Networks
Christoforos Somarakis, Guangyi Liu, Nader Motee
We develop a framework to quantify systemic risk measures in a class of Wide-Area-Control (WAC) laws in power networks in the presence of noisy and time-delayed sensory data. A clo…
Emergence of Cascading Risk and Role of Spatial Locations of Collisions in Time-Delayed Platoon of Vehicles
Guangyi Liu, Christoforos Somarakis, Nader Motee
We develop a framework to assess the risk of cascading collisions in a platoon of vehicles in the presence of exogenous noise and communication time-delay. The notion of Value-at-R…
