Design of a beamforming-based antenna for detecting environmental noise in a city framework
Measurement: Sensors, 2021 The noise magnitude should be drastically limited in any city whatever its source, namely car/train/aircraft traffic, industrial activities, and leisure. The nose pollution has a significant impact on human activities especially for health.

Searching With Measurement Dependent Noise [PDF]
IEEE Transactions on Information Theory, 2014 Consider a target moving at a constant velocity on a unit-circumference circle, starting at an arbitrary location. To acquire the target, any region of the circle can be probed to obtain a noisy measurement of the target's presence, where the noise level increases with the size of the probed region.

Influence of Noise on Force Measurements [PDF]
Physical Review Letters, 2010 We demonstrate how the ineluctable presence of thermal noise alters the measurement of forces acting on microscopic and nanoscopic objects. We quantify this effect exemplarily for a Brownian particle near a wall subjected to gravitational and electrostatic forces.

An Efficient Cross-Correlation Method for a Digital Phase Noise Measurement System [PDF]
Journal of Electromagnetic Engineering and Science, 2022 In this paper, we propose a digital phase noise measurement using a 10-bit digital oscilloscope MXR608A from Keysight Technologies. The digital oscilloscope’s four channel data are used for digital phase noise measurement: two channels are assigned for ...
