针对在瞬态电压的扰动多个敏感负载的同时保护，设计一种基于超导磁储能的模块化电流型多馈线间动态电压恢复器的电力装置。基于超导线圈的特性，采用电流源型变流器将补偿信号由直流转换为交流，为提高储能利用率，将多条馈线上的DVR与同一个超导磁储能系统连接，根据三相电磁量的对称分解理论，设计变流器的电压双重PI控制策略，建立两条馈线的仿真模型，结果表明在系统发生电压暂降和暂升故障时，该装置可以快速有效地对电压进行补偿，从而实现对多馈线上负载的保护。

Insights into Manipulation: Unveiling Tampered Images Using Modified ELA, Deep Learning, and Explainable AI

Journal of Computer and Communications 2024年第6期12卷 135-151页

作者： Md. Mehedi Hasan Md. Masud Rana abu Sayed Md. Mostafizur Rahaman Department of Information and Communication Technology Bangladesh University of Professionals Dhaka Bangladesh Department of Computer Science and Engineering Jahangirnagar University Dhaka Bangladesh

Digital image forgery (DIF) is a prevalent issue in the modern age, where malicious actors manipulate images for various purposes, including deception and misinformation. Detecting such forgeries is a critical task for maintaining the integrity of digital content. This thesis explores the use of Modified Error Level Analysis (ELA) in combination with a Convolutional Neural Network (CNN), as well as, Feedforward Neural Network (FNN) model to detect digital image forgeries. Additionally, incorporation of Explainable Artificial Intelligence (XAI) to this research provided insights into the process of decision-making by the models. The study trains and tests the models on the CASIA2 dataset, emphasizing both authentic and forged images. The CNN model is trained and evaluated, and Explainable AI (SHapley Additive exPlanation— SHAP) is incorporated to explain the model’s predictions. Similarly, the FNN model is trained and evaluated, and XAI (SHAP) is incorporated to explain the model’s predictions. The results obtained from the analysis reveals that the proposed approach using CNN model is most effective in detecting image forgeries and provides valuable explanations for decision interpretability.
