The d-identifying codes problem for vertex identification in graphs: Probabilistic analysis and an approximation algorithm
(2006)Given a graph G(V, E), the identifying codes problem is to find the smallest set of vertices D ⊆ V such that no two vertices in V are adjacent to the same set of vertices in D. The identifying codes problem has been applied ...

DC Interference Modeling for Assessing the Impact of Sustained DC Ground Faults of Photovoltaic Systems on Third-Party Infrastructure
(2019)In grounded photovoltaic (PV) systems, dc leakage to earth is formed by the contribution of the PV modules, inverters, and dc circuitry. Ground faults in such systems occur when there is an unintentional connection between ...

Decentralised minimum-time average consensus in digraphs
(Institute of Electrical and Electronics Engineers Inc., 2013)Distributed algorithms for average consensus in directed graphs are typically asymptotic in the literature. In this work, we propose a protocol to distributively reach average consensus in a finite number of steps on ...
