Propagation Stability Concepts for Network Synchronization Processes
Sandip Roy, Subir Sarker, Mengran Xue
A notion of disturbance propagation stability is defined for dynamical network processes, in terms of decrescence of an input-output energy metric along cutsets away from the distu…
Distinguishing Aerial Intruders from Trajectory Data: A Model-Based Hypothesis-Testing Approach
David Petrizze, Kasra Koorehdavoudi, Mengran Xue +1
Motivated by security needs in unmanned aerial system (UAS) operations, an algorithm for identifying airspace intruders (e.g., birds vs. drones) is developed. The algorithm is stru…
Compressibility of Network Opinion and Spread States in the Laplacian-Eigenvector Basis
Sandip Roy, Mengran Xue
Opinion-evolution and spread processes on networks (e.g., infectious disease spread, opinion formation in social networks) are not only high dimensional but also volatile and multi…
Cyber-Physical Queueing-Network Model for Risk Management in Next-Generation Emergency Response Systems
Mengran Xue, Sandip Roy
Queueing-network models are developed for enhanced and next-generation 911 (E911 and NG911) systems, which capture both their cyber-components (communications, data-processing) and…
Averager-copier-voter models for hybrid opinion dynamics in complex networks
Mengran Xue, Sandip Roy
A hybrid model for opinion dynamics in complex multi-agent networks is introduced, wherein some continuous-valued agents average neighbors' opinions to update their own, while othe…
Controllability-Gramian Submatrices for a Network Consensus Model
Sandip Roy, Mengran Xue
Principal submatrices of the controllability Gramian and their inverses are examined, for a network-consensus model with inputs at a subset of network nodes. Specifically, several…
Sign Patterns of Inverse Doubly-Nonnegative Matrices
Sandip Roy, Mengran Xue
The sign patterns of inverse doubly-nonnegative matrices are examined. A necessary and sufficient condition is developed for a sign matrix to correspond to an inverse doubly-nonneg…
Comment on `Detecting Topology Variations in Networks of Linear Dynamical Systems'
Sandip Roy, Mengran Xue
Conditions for the detectability of topology variations in dynamical networks are developed in a recent article in the IEEE Transactions on Control of Network Systems [1]. Here, an…
Modal Barriers to Controllability in Networks with Linearly-Coupled Homogeneous Subsystems
Mengran Xue, Sandip Roy
The controllability of networks comprising homogeneous multi-input multi-output linear subsystems with linear couplings among them is examined, from a modal perspective. The eigenv…
