A Shallow Seafloor Reverberation Simulation Method Based on Generative Adversarial Networks

Applied Sciences, 2023
Reverberation characteristics must be considered in the design of sonar. The research on reverberation characteristics is based on a large number of actual reverberation data.

Computationally-Efficient Simulation of Late Reverberation for Inhomogeneous Boundary Conditions and Coupled Rooms

Journal of The Audio Engineering Society, 2023
For computational efficiency, acoustic simulation of late reverberation can be simplified by generating a limited number of incoherent signals with frequency-dependent exponential decay radiated by spatially distributed virtual reverberation sources (VRS)

The Sloan Digital Sky Survey Reverberation Mapping Project: Estimating Masses of Black Holes in Quasars with Single-epoch Spectroscopy [PDF]

Astrophysical Journal, 2020
It is well known that reverberation mapping of active galactic nuclei (AGNs) reveals a relationship between AGN luminosity and the size of the broad-line region, and that use of this relationship, combined with the Doppler width of the broad emission ...

A dynamic black hole corona in an active galaxy through X-ray reverberation mapping [PDF]

Nature Astronomy, 2020
X-ray reverberation echoes are assumed to be produced in the strongly distorted spacetime around accreting supermassive black holes. This signal allows us to spatially map the geometry of the inner accretion flow 1 , 2 —a region that cannot yet be ...

Reverberation Suppression Method for Active Sonar Systems Using Non-Negative Matrix Factorization With Pre-Trained Frequency Basis Matrix

IEEE Access, 2021
In active sonar systems, detection always suffers from reverberation interference from multiple scatterers in oceanic environments; therefore, numerous studies have been conducted on reverberation suppression.

Reverberation Measurements for 17 Quasars and the Size-Mass-Luminosity Relations in Active Galactic Nuclei [PDF]

, 1999
Correlated variations in the line and continuum emission from active galactic nuclei (AGNs) can be used to determine the size and geometry of the broad emission-line regions (BLRs).
