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.

Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers
The Canadian Journal of Chemical Engineering, EarlyView.This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Firms are experiencing mounting pressure to report their environmental impact. Rather than disclosing their actual performance, however, some are engaging in unethical business (i.e., greenwashing) practices. Prior studies have contributed significantly to the greenwashing literature from varied perspectives, but a comprehensive understanding ...

Dynamic Peak Threshold Estimation Method for Noise Mitigation in Hybrid PLC/VLC Systems
IEEE AccessMost communication systems suffer from signal distortions as a result of noise interference. These distortions have multiple effects on communication channels, including higher bit error rate (BER), reduced signal-to-noise ratio (SNR), and restricted ...

Speech Denoising Using Transform Domains in the Presence of Impulsive and Gaussian Noises
IEEE Access, 2017 The speech denoising problem in the presence of mixed impulsive and Gaussian noises is investigated by exploiting transform domains. To that end, the proposed noise suppression scheme is a cascaded form consisting of an impulsive noise suppression module
