Calibration of otoacoustic emission probe microphones [PDF]

The Journal of the Acoustical Society of America, 2011
Recently, investigators of otoacoustic emissions (OAEs) have shown interest in measuring OAEs to frequencies higher than 10 kHz. Most commercial instruments used to measure OAEs do not specify the microphone frequency response at higher frequencies, nor does their typically integrated design make it convenient to measure it.

Updated Calibration of the LOFAR Low-Band Antennas [PDF]

EPJ Web of Conferences, 2019
The LOw-Frequency ARray (LOFAR) telescope measures radio emission from air showers. In order to interpret the data, an absolute, frequency dependent calibration is required.

Optimal Integrated Emission Management through Variable Engine Calibration

Energies, 2021
In this work, the potential for improving the trade-off between fuel consumption and tailpipe NOx emissions through variable engine calibration (VEC) is demonstrated for both conventional and hybrid electric vehicles (HEV).

Measuring and calibrating galactic synchrotron emission [PDF]

Proceedings of the International Astronomical Union, 2008
AbstractOur position inside the Galaxy requires all-sky surveys to reveal its large-scale properties. The zero-level calibration of all-sky surveys differs from standard ‘relative’ measurements, where a source is measured in respect to its surroundings.

Detailed reproduction of the neutron emission from the compact DT neutron generator used as an in-situ 14 MeV calibration neutron source at JET [PDF]

EPJ Web of Conferences, 2020
A compact DT neutron generator (NG) based on the mixed-beam operation was used as a calibration neutron source in the latest in-situ calibration of neutron detectors at the Joint European Torus (JET).

Introducing an interesting and novel strategy based on exploiting first-order advantage from spectrofluorimetric data for monitoring three toxic metals in living cells

Toxicology Reports, 2022
In this work, we did our best to develop a novel and interesting analytical method based on coupling of spectrofluorimetry with first-order multivariate calibration techniques for simultaneous determination of lead (Pd), zinc (Zn) and cadmium (Cd) in ...

Two Independent Light Dilution Corrections for the SO₂ Camera Retrieve Comparable Emission Rates at Masaya Volcano, Nicaragua

Remote Sensing, 2021
SO2 cameras are able to measure rapid changes in volcanic emission rate but require accurate calibrations and corrections to convert optical depth images into slant column densities.

Bar-Wave Calibration of Acoustic Emission Sensors

Applied Sciences, 2017
This study extended a bar-wave calibration method for acoustic emission (AE) sensors. It combined laser interferometer displacement measurements and the wave propagation medium of a long bar, excited at its end with an ultrasonic transducer driven by a ...
