From Ellipsoids to Midair Control of Dynamic Hitches
Jiawei Xu, Subhrajit Bhattacharya, David Saldaña
The ability to manipulate and interlace cables using aerial vehicles can greatly improve aerial transportation tasks. Such interlacing cables create hitches by winding two or more…
Distributed Optimization of Bivariate Polynomial Graph Spectral Functions via Subgraph Optimization
Jitian Liu, Nicolas Kozachuk, Subhrajit Bhattacharya
We study distributed optimization of finite-degree polynomial Laplacian spectral objectives under fixed topology and a global weight budget, targeting the collective behavior of th…
Spectrum Optimization of Dynamic Networks for Reduction of Vulnerability Against Adversarial Resonance Attacks
Alp Sahin, Nicolas Kozachuk, Rick S. Blum +1
Resonance is a well-known phenomenon that happens in systems with second order dynamics. In this paper we address the fundamental question of making a network robust to signal bein…
Trace of Multi-variable Matrix Functions and its Application to Functions of Graph Spectrum
Subhrajit Bhattacharya
Matrix extension of a scalar function of a single variable is well-studied in literature. Of particular interest is the trace of such functions. It is known that for diagonalizable…
