Distribution of generated friction heat at wheel-rail contact during wheel slipping acceleration
, 2016 This paper presents an innovative method for determining the distribution of the friction generated heat from the contact of a locomotive wheel and rail, as well as the heat partition factor, during wheel slipping of an accelerating locomotive.

WearIn desert environments, the phenomenon of sand particles depositing on the rail top and contaminating the wheel-rail interface is common because the railway is an open system. This work aimed to investigate the wear and damage behaviors of wheel-rail with different material matchings under various sand deposition densities of rail top in desert ...

Review of Memristors for In‐Memory Computing and Spiking Neural Networks
Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.Memristors uniquely enable energy‐efficient, brain‐inspired computing by acting as both memory and synaptic elements. This review highlights their physical mechanisms, integration in crossbar arrays, and role in spiking neural networks. Key challenges, including variability, relaxation, and stochastic switching, are discussed, alongside emerging ...
