Distribution based definition of impulse noise [PDF]
The Journal of the Acoustical Society of America, 1985 Existing definitions of impulse noise are based on estimates of either the decay of the noise envelope, the repetition rate of the peaks, or a comparison of single peak level to rms level. Because each of these measures fails to fully characterize at least one of the relevant characteristics of an impulse, many exceptions to these classifications can ...

British Educational Research Journal, EarlyView.Abstract Character education research is often constrained by blunt methodological tools. Surveys capture breadth without depth; case studies offer richness but lack replicability; and randomised controlled trials (RCTs), though indispensable at the policy level, are costly, disruptive and ill‐suited to everyday practice with individual pupils.

The effects of periodic impulsive noise on OFDM
, 2015 : The effect of periodic impulsive (short duration) noise on OFDM is investigated. We present results on the nature of periodic impulsive noise, showing that the PDF of periodic impulsive noise is not exactly Gaussian.

Berichte zur Wissenschaftsgeschichte, EarlyView.Since late 2021, serious allegations have been made against physicist Erwin Schrödinger, ranging from pedophilia to serial sexual abuse. These accusations have significantly tarnished the Nobel Prize winner's public reputation. The ongoing debate has repeatedly raised the question of whether, and to what extent, these grave allegations are justified ...

Interpolation‐based impulse noise removal
IET Image Processing, 2013 Interpolation‐Based Impulse Noise Removal (IBINR), a fast and simple algorithm is proposed to remove fixed valued impulse noise in this study. The proposed method removes all noisy pixels from the image and determines their values using non‐linear interpolation.
