Enhancing Fault Tolerance In Distributed Systems Using Shared Checkpoint Replica Mechanisms, Ameer A. Mousa, Mahdi S. Almhanna Sep 2025

Enhancing Fault Tolerance In Distributed Systems Using Shared Checkpoint Replica Mechanisms, Ameer A. Mousa, Mahdi S. Almhanna

Journal of Intelligent Informatics, Networking, and Cybersecurity

Fault tolerance is a critical requirement in distributed systems, as node and network failures can cause significant data loss, service disruption, and performance degradation. Traditional fault-tolerance methods often provide partial solutions, relying on separate recovery models for errors and delayed responses, while also incurring high resource costs. This paper aims to design and implement a more robust and efficient fault-tolerant architecture based on the concept of a shared checkpoint replica. In the proposed system, a master server and multiple slave servers collaboratively process client requests, share checkpoint replicas, and ensure seamless recovery in case of failures.

Practitioners’ Perspectives On Preventing Environmental Gentrification In Chicago, Illinois, Usa, Tania Schusler, Amy Krings

School of Environmental Sustainability: Faculty Publications and Other Works

Pollution cleanup, green space creation, and other improvements to environmental quality in cities are important to urban sustainability. However, because they occur within a political economic context characterized by structural racism, urban greening initiatives can intentionally or unintentionally reproduce racial, economic, and social inequities through environmental gentrification. We explored possibilities for improving environmental quality without displacing or excluding long-term residents including people of color, the poor, and members of other marginalized groups. We conducted in-depth, semi-structured interviews with community organizers, environmental justice advocates, urban planners, housing specialists, and others who held deep expertise through their lived and professional experience in …

Abstract: A deep fuzzy neural network (DFNN) is proposed to solve the problem that the deep neural network has poor interpretability and the correction of the model is not targeted when dealing with the big data regression prediction problem. The proposed deep fuzzy neural network adopts an adaptive fuzzy Cmeans (AFCM) clustering algorithm in structural learning. The structure of the model, namely the number of rules and the antecedent parameters of the rules, is determined by calculating the introduced validity function. The identification of consequent parameters uses an improved grey wolf optimization (IGWO) algorithm. By replacing the linear decreasing strategy …
