Production grinding burn detection using acoustic emission and electric power signals
(1999-12-01)
This work uses a monitoring system based on a PC platform, where the acoustic emission and electric power signals generated during the grinding process are used to investigate superficial burning occurrence in a surface ...
Feature extraction based on the high-pass filtering of audio signals for Acoustic Event Classification
(Academic Press, 2015)
In this paper, we propose a new front-end for Acoustic Event Classification tasks (AEC). First, we study the spectral characteristics of different acoustic events in comparison with the structure of speech spectra. Second, ...
Complex acoustic signals in Crossodactylodes (Leptodactylidae, Paratelmatobiinae): a frog genus historically regarded as voiceless
(Taylor & Francis Ltd, 2021-04-05)
Vocal sounds occur in most anurans and are often emitted as simple and stereotyped acoustic signals. Some frog groups, however, have complex signals and others can produce distinctive acoustic structures, such as purely ...
Components of the acoustic swallowing signal: Preliminary study
(2012-12-01)
Purpose: To analyze the components of the acoustic signal of swallowing using a specific software. Methods: Fourteen healthy subjects ranging in age from 20 to 50 years (mean age 31±10 years), were evaluated. Data collection ...

Monitoring the dressing operation in the grinding process
(2009-03-03)
This work was based on a methodology of development and experimentation, and involved monitoring the dressing operation by processing the acoustic emission and electric power signals to detect the optimal dressing moment. ...
Revisiting the drivers of acoustic similarities in tropical anuran assemblages
(2021-01-01)
Acoustic signaling is key in mediating mate choice, which directly impacts individual fitness. Because background noise and habitat structure can impair signal transmission, the acoustic space of mixed-species assemblages ...
Simplified inverse filter tracked affective acoustic signals classification incorporating deep convolutional neural networks
Facial expressions, verbal, behavioral, such as limb movements, and physiological features are vital ways for affective human interactions. Researchers have given machines the ability to recognize affective communication ...
INVESTIGATION OF ACOUSTIC SIGNALS AS A TOOL FOR CHARACTERIZING SPOUTED BED DYNAMICS
(JOHN WILEY & SONS INC, 2009)
The feasibility of characterizing the dynamics of a spouted bed based on acoustic emission (AE) signals is evaluated. Acoustic emission signals were measured in a semi-cylindrical Plexiglas column of diameter 150 mm and ...
Acoustic emission signals resulting from the dryinginduced fractures of Phyllostachys pubescens bamboo: evidence of scale free phenomena
Acoustic Emission (AE) is a noninvasive tool for evaluation of damage
and fracture. In this paper, results of AE study of the drying process of Phyllostachys
pubescens bamboo are reported. The histogram of experimental ...
