Localized Resonance Mechanism of Rail Corrugation and Active Suppression via Wheel–Rail Self-Grinding on Urban Express Line with Different Tracks

Applied Sciences
The occurrence of short-wave corrugation with wavelengths of 32–44 mm on curved sections of urban express railway lines is particularly pronounced, yet the underlying initiation mechanisms have remained insufficiently understood.

Measuring the Corrugation Amplitude of Suspended and Supported Graphene

, 2020
Nanoscale corrugation is a fundamental property of graphene arising from its low-dimensional nature. It places a fundamental limit to the conductivity of graphene and influences its properties.

Tunable active chirped-corrugation waveguide filters [PDF]

, 1989
A novel tunable semiconductor waveguide reflection filter is proposed and analyzed. The filter is based on spatially selective gain pumping of a chirped-corrugation waveguide.

Rail corrugation growth on curves - measurements, modelling and mitigation

, 2015
The development of rail corrugation (so called rutting corrugation) on a 120 m radius curve on the metro of Stockholm Public Transport was studied by field measurements, laboratory measurements and numerical simulations.

Diverse corrugation pattern in radially shrinking carbon nanotubes [PDF]

, 2010
Stable cross sections of multiwalled carbon nanotubes subjected to electron-beam irradiation are investigated in the realm of the continuum mechanics approximation. The self-healing nature of sp2 graphitic sheets implies that selective irradiation of the

Corrugation Reduction by Semi-Active Track

, 2000
The wear of wheels and rails is of major concern for every railway and vehicle maintenance authority, since reprofiling and replacing worn wheels and rails absorb a significant part of their maintenance budget.

Morphological and morphometric aspects of the equine aortic valve: New insights for comparative studies in mammals

The Anatomical Record, EarlyView.
Abstract New data on the equine aortic valve obtained using advanced techniques is especially important given the greater availability of animal models for translational research. Here we characterized the morphological and morphometric aspects of the equine aortic valve from 60 healthy hearts collected at equine abattoirs.

Acoustic vibration characteristics for combined diagnosis of rail corrugation: An application of MCiSSA and permutation heterogeneous recurrence plot

Results in Engineering
In this paper, we utilize acoustic vibration characteristics for the combined diagnosis of rail corrugation. The two-dimensional signal is first decomposed into several modes by Multivariate circulant singular spectrum analysis (MCiSSA) and the ...
