The Measurement and Analysis of the Disc/Pad Interface Dynamic Centre of Pressure and its Influence on Brake Noise. [PDF]

open access: yes, 2008
This paper discusses the measurement of the dynamic centre of pressure (CoP) of a brake pad during a normal braking event using a modified 12-piston opposed calliper. The modifications allow the centre of pressure to be controlled both radially and along

Uncertainty Analysis in the Noise Parameters Estimation

open access: yesMATEC Web of Conferences, 2012
The new approach to the uncertainty estimation in modelling acoustic hazards by means of the interval arithmetic is presented in the paper. In the case of the noise parameters estimation the selection of parameters specifying the acoustic wave ...

On the behavior of EMD and MEMD in presence of symmetric alpha-stable noise [PDF]

open access: yes, 2014
EmpiricalMode Decomposition (EMD) and its extended versions such as Multivariate EMD (MEMD) are data-driven techniques that represent nonlinear and non-stationary data as a sum of a finite zero-mean AM-FM components referred to as Intrinsic Mode ...

An Improved Method for InP HEMT Noise-Parameter Determination Based on 50-Ω Noise Measurements

open access: yesIEEE Journal of the Electron Devices Society
In this paper, we propose an improved method for extracting the four noise parameters of InP HEMT devices based on a 50- $\Omega $ noise measurement system. The noise equivalent circuit and noise correlation matrix technique is combined with 50- $\Omega

A Study on Distortion Estimation Based on Image Gradients

open access: yesSensors, 2022
Image noise is a variation of uneven pixel values that occurs randomly. A good estimation of image noise parameters is crucial in image noise modeling, image denoising, and image quality assessment.

Effect of Profile Modification on Noise in Involute Gear Pair

open access: yesInternational Journal of Automotive Science and Technology, 2021
Ensuring regular movement and power transmission in gear wheels is possible with a suitable tooth profile. Although involute profiles have a structure that can provide conjugate movement in accordance with the law of gearing, transmission errors that ...

Parameter estimation of impulsive noise for channel coded communication systems

open access: yesIET Communications, 2021
In this paper, an impulsive noise estimation algorithm for generating bit log‐likelihood ratios (LLRs) for channel coded systems in impulsive noise environments is proposed. This approach is to design the LLR detector in the maximum‐likelihood (ML) sense,

Weak–Noise Modulation–Estimation of Vector Parameters [PDF]

open access: yes2020 IEEE International Symposium on Information Theory (ISIT), 2020
We address the problem of modulating a parameter onto a power-limited signal, transmitted over a discrete-time Gaussian channel and estimating this parameter at the receiver. Continuing an earlier work, where the optimal trade-off between the weak-noise estimation performance and the outage probability (threshold-effect breakdown) was studied for a ...
