Real-Time Inspection System for Ballast Railway Fasteners Based on Point Cloud Deep Learning
IEEE Access, 2020 Rail fasteners are the most numerous components in railways and they should be inspected periodically. Manual inspection is currently a common solution, which is laborious and low-efficient. Some automatic inspection approaches are proposed.

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 7, Page 1514-1532, June 2026.ABSTRACT The rapid development of new railway networks and the aging of existing infrastructure in seismic‐prone regions continue to motivate the need for efficient methods to simulate the dynamic behavior of coupled train track structure systems. While detailed train–structure interaction (TSI) models can capture complex mechanisms, they are often too

CRITICAL TEMPERATURE ON CURVED SUPERELEVATED RAILWAYS
ce/papers, Volume 9, Issue 1, Page 342-351, April 2026.Abstract Railways are essential for the efficient transport of people and cargo, but they face increasing risks due to temperature variations. This study analyses thermal instability in continuously welded rails located on curves with superelevation.

The Economic History Review, Volume 79, Issue 1, Page 57-88, February 2026.Abstract This paper contributes to the understanding of the complex relationship between British economic performance during the Napoleonic wars and the ‘West Indies’, as the Caribbean slave colonies were called. Not only did profits from slave‐based commerce provide financing for the growth of the financial sector, as has been claimed, but the risk of

Analytical Frameworks and Theories of Electric Power in Non‐Linear Circuits
IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.Based on the challenges of distorted currents and non‐linear components in modern power grids, this article reviews seminal electrical power theories that seek to generalize the traditional definitions of active, reactive, and apparent power. It provides a detailed analysis of their mathematical foundations, practical implementation, and validity.
