Comparative Study of Image Denoising Using Wavelet Transforms and Optimal Threshold and Neighbouring Window

مجلة كلية التربية للبنات, 2019
NeighShrink is an efficient image denoising algorithm based on the discrete wavelet transform (DWT). Its disadvantage is to use a suboptimal universal threshold and identical neighbouring window size in all wavelet subbands.

Statistical inference based on score functions of distribution

Research in Statistics
In recent decades, a number of articles have appeared expanding and applying the basic framework of Stein’s method for estimating parameters by minimizing the distance between the score function of the data and of the model.

A Dynamic Business Modeling Approach to Port Sustainability: The Western Sicily Port Authority Case

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Ports are critical nodes in global trade and economic development, yet they generate substantial environmental and social externalities—including greenhouse gas emissions, air, noise, and water pollution, and adverse impacts on host communities—that demand integrated and forward‐looking governance.

Integrating Wavelet Shrinkage with SURE and Minimax Thresholding to Enhance Maximum Likelihood Estimation for Gamma-Distributed Data

المجلة العراقية للعلوم الاحصائية
This paper uses the Maximum Likelihood Estimation method to investigate the impact of data contamination on the accuracy of parameter estimation for the Gamma distribution. A de-noising approach based on wavelet shrinkage has been proposed to address the

Can AI Write Authentic CSR? Effects of Message Source Across Informational and Narrative CSR Communication

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT As artificial intelligence (AI)‐generated messages increasingly approach human‐level quality, can AI effectively substitute human authors in value‐laden brand communications such as corporate social responsibility (CSR) messaging? This study examines how CSR message source (AI‐generated vs.

Empirical Bayes Estimators for Mean Parameter of Exponential Distribution with Conjugate Inverse Gamma Prior Under Stein’s Loss

Mathematics
A Bayes estimator for a mean parameter of an exponential distribution is calculated using Stein’s loss, which equally penalizes gross overestimation and underestimation.

Winning Consumer Trust Through Supply Chain Responsibility Communication: How Certification, Disclosure, and Beneficiary Framing Shape Credibility

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT As stakeholders increasingly demand supply chain transparency, companies face a legitimacy paradox: disclosing supply chain responsibility (SR) information is necessary to meet stakeholder expectations, yet disclosure can invite scrutiny rather than build credibility.

Multipath-Aware Hybrid Adaptive Wavelet Thresholding for Denoising Underwater Acoustic BPSK Communication Signals

International Journal of Emerging Research in Engineering, Science, and Management
This paper presents a hybrid adaptive wavelet thresholding method for denoising underwater multipath Binary Phase Shift Keying (BPSK) communication signals corrupted by real ambient noise.

Leading for Sustainability in Uncertain Times: How Paradoxical Leadership, Green Proactive Behaviour and Employee Ambidexterity Shape Sustainability Performance

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT As organisations confront growing environmental uncertainty, achieving sustainability requires more than formal policies; it depends on how leaders and employees respond to competing demands for stability, adaptation and environmental action. Although prior research has examined leadership, employee behaviour and sustainability outcomes, these
