Right after its invention in the late nineties, Frequency Domain Decomposition (FDD) identification technique became very popular operational modal analysis community due to simplicity and robustness. The underlying idea of this consists computing singular value decomposition Power Spectral Densities (PSDs) estimated from measured vibration responses with periodogram (also known as “Welch’s”) a...

This paper studies the joint community detection and phase synchronization problem on stochastic block model with relative phase , where each node is associated an unknown angle. problem, a variety of real-world applications, aims to recover cluster structure angles simultaneously. We show this...
