Comparison of Neuro‐Fuzzy and Neural Network Techniques for Estimating the Line Voltage of 8E Electrical Locomotives

open access: yesInternational Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
The South African rail sector is a key contributor to the national economy, boosting gross domestic product (GDP) and creating jobs. However, serious malfunctions often jeopardize the reliability of locomotives such as the Class 8E locomotive, leading to lost output and longer lead times.

Safety Assessment of Critical Aircraft Systems Under Multisource Uncertainty Based on Evidence Network

open access: yesInternational Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
As civil aircraft components become more autonomous in China, airworthiness certification is facing the problem of insufficient failure data, leading to challenges in terms of uncertainty. Traditional probabilistic models struggle to effectively integrate multisource uncertainties, limiting their application in data‐scarce scenarios.

Quantitative Assessment of Human Factors in Civil Aircraft Flight Test Risks Based on Fuzzy Bayesian Network and Improved HFACS Model

open access: yesInternational Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
Human factors play an important role in civil aviation safety, which is also vital in flight tests. To significantly reduce the possibility of accidents induced by human errors during the flight test, systematic assessment of human factor risks, determination of the critical causes of accidents, and designs of targeted preventive strategies are ...

Adaptive Grid‐Forming Controller With Virtual Inertia and Damping for Enhanced Frequency Stability in Renewable Energy Systems

open access: yesJournal of Electrical and Computer Engineering, Volume 2026, Issue 1, 2026.
The increasing integration of renewable energy systems (RESs) such as solar and wind into modern power grids using converter‐based, inertia‐less interfaces poses serious frequency stability challenges. This is due to reduced system inertia conventionally provided by synchronous generators.
