Noise: towards a definition [PDF]

open access: yes
The research aims to explore the perceptual affects of noise on the relationship between performers, their instruments and listeners. The portfolio of compositions and accompanying thesis demonstrates the results of this treatment of sound and space ...

Noise in and as music [PDF]

open access: yes, 2013
One hundred years after Luigi Russolo’s “The Art of Noises,” this book exposes a cross-section of the current motivations, activities, thoughts, and reflections of composers, performers, and artists who work with noise in all of its many forms.

Extraction of black hole coalescence waveforms from noisy data

open access: yesPhysics Letters B, 2018
We describe an independent analysis of LIGO data for black hole coalescence events. Gravitational wave strain waveforms are extracted directly from the data using a filtering method that exploits the observed or expected time-dependent frequency content.

Removing noise and overlapping spikes from extracellular recordings using a regularized denoising autoencoder

open access: yesCurrent Directions in Biomedical Engineering, 2023
One of the difficulties in sorting extracellularly recorded neuronal action potentials, known as spikes, is noise from several sources superimposed on the target spike.

Time–frequency​ characteristics of abnormal waveshapes in PD pulse sequence using ultra-wideband detection

open access: yesEnergy Reports, 2023
In the present study, a HVDC PD test platform with bandwidth of 10 kHz–50 MHz and 250 MS/s sampling rate is built for the ultra-wideband (UWB) detection and investigation of time–frequency (T–F) characteristics of abnormal waveshapes or waveforms in PD ...

On the Analysis of PM/FM Noise Radar Waveforms Considering Modulating Signals with Varied Stochastic Properties

open access: yesSensors, 2021
Noise Radar technology is the general term used to describe radar systems that employ realizations of a given stochastic process as transmit waveforms. Originally, carriers modulated in amplitude by a Gaussian random signal, derived from a hardware noise

Are the comfort classes noise and vibration levels on board really suitable?

open access: yes, 2021
In shipbuilding industry, comfort is a relevant issue both for crew members and passengers. A comfortable environment enables crew members to perform accurately their tasks and it is an effective factor contributing to the satisfaction of passengers ...

Noise and Vibration Characteristic Studies of Twin Screw Compressor in Different Operating Conditions [PDF]

open access: yes, 2012
The tonal noise or vibration of air-cooled or water-cooled chillers with rotary twin screw compressors is crucial for environmental concerns. This work aims to perform the receiver tests regarding the radiated noise and structural vibration due to the ...

Chirp Signals and Noisy Waveforms for Solid-State Surveillance Radars

open access: yesAerospace, 2017
Since the advent of “pulse compression” radar, the “chirp” signal (Linear Frequency Modulation, LFM) has been one of the most widely used radar waveforms.

Using the Features Extracted From the Ambient Noise Cross-Correlation Function to Evaluate the Performance of Broadband Seismograph

open access: yesIEEE Access, 2022
Broadband seismographs are used to collect seismic data over an extended period. Temperature, pressure, and humidity are field variables that can have an impact on the broadband seismograph’s performance as well as the accuracy of observational ...
