Thermoacoustic instability - a dynamical system and time domain analysis
, 2014 This study focuses on the Rijke tube problem, which includes features relevant to the modeling of thermoacoustic coupling in reactive flows: a compact acoustic source, an empirical model for the heat source, and nonlinearities.

Raking the Cocktail Party [PDF]
, 2014 We present the concept of an acoustic rake receiver---a microphone beamformer that uses echoes to improve the noise and interference suppression. The rake idea is well-known in wireless communications; it involves constructively combining different ...

Location of Tensile Damage Source of Carbon Fiber Braided Composites Based on Two-Step Method
Molecules, 2019 Acoustic emission (AE) source localization is one of the important purposes of nondestructive testing. The localization accuracy reflects the degree of coincidence between the identified location and the actual damage location. However, the anisotropy of

Acoustic emission partial discharge detection technique applied to fault diagnosis: Case studies of generator transformers [PDF]
Serbian Journal of Electrical Engineering, 2016 In power transformers, locating the partial discharge (PD) source is as important as identifying it. Acoustic Emission (AE) sensing offers a good solution for both PD detection and PD source location identification.

Sound predictability as a higher-order cue in auditory scene analysis [PDF]
, 2013 A major challenge for the auditory system is to disentangle signals emitted by two or more sound sources that are active in a temporally interleaved manner (sequential stream segregation). Besides distinct characteristics of the individual signals (e.g.,
