Rail Profile Matching Assessment and Selection for Sharp Radius Curves in Urban Metro: A Case Study

Urban Rail Transit
Urban rail transit systems contain numerous sharp radius curves where rail fatigue defect occurs frequently. In severe cases, this leads to extensive rail scaling, rail surface fatigue cracks, and intensified wheel-rail vibration and noise.

Affordable and Clean Energy: CO2 Emissions, Resilience and Inequality

Sustainable Development, EarlyView.
ABSTRACT Sustainable development means building the resilience of both people and the planet. It includes implementing strategies which reduce emissions while also enabling more vulnerable households to transition to clean and affordable energy. This paper examines household CO2 emissions in Ireland to highlight those who emit most and least in key ...

Investigation of the Reoxidation and Material Behavior of Directly Reduced Pellets and Fines Under Simulated Rail Transport Conditions

steel research international, EarlyView.
The study investigates the reoxidation behavior of DRI pellets (Midrex and H2‐reduced) under realistic conditions, considering the test parameters of temperature, humidity, storage duration, particle size (including fine fraction), and container geometry. The samples are analyzed based on mass changes.
