A study of the head checks development on the low rail and the contact condition between wheel/rail on its appearance site

open access: yesNihon Kikai Gakkai ronbunshu, 2019
Rail is the peculiar element constructing the railway system. The phenomenon such as wear or defect of rail will be caused by the repeated wheel and rail rolling contact on the rail surface.

Do the public take action when a severe snow warning is issued?

open access: yesWeather, EarlyView.
Extreme weather events pose significant risks to the population, making timely warnings essential for preparedness. The UK Met Office’s National Severe Weather Warning Service (NSWWS) has issued impact‐based alerts for over a decade, yet evaluations of their effectiveness remain limited.

An Overview of High‐Temperature Superconducting Cables in DC Systems: Unlocking Potential for High‐Voltage DC Networks

open access: yesHigh Voltage, EarlyView.
ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...

Reliability of rail transverse flaw detection by means of an embedded ultrasonic based device

open access: yesMATEC Web of Conferences, 2018
The main causes of train derailment are related to rail defects such as head surface defects, horizontal defects, vertical longitudinal split defects, star cracks at colt holes and diagonal crack in web. The most adverse form of these defects consists of

Forces Behind South Australia's Unusual Structural Changes Since 1840

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT The agricultural sector's share of GDP in growing economies typically declines but, for a century from the early 1850s, Australia's did not. That trend is most evident for the former colony and now State of South Australia (SA). Moreover, that share for SA has been almost flat since 1980 as well, along with the agricultural sector's share of ...

MIRACLE URBANIZATION: Spatial Production and Political Legitimation in the Sochi 2014 and Beijing 2022 Olympics

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract From desert ski resorts to subtropical Winter Games, there is a global proliferation of ‘mission‐impossible’ mega‐projects. The prevailing frameworks of city branding and urban entrepreneurism fail to explain the political logics behind these seemingly irrational projects.

Research on Rail Surface Defect Detection Based on Improved CenterNet

open access: yesElectronics
Rail surface defect detection is vital for railway safety. Traditional methods falter with varying defect sizes and complex backgrounds, while two-stage deep learning models, though accurate, lack real-time capabilities.
