Experimental study on wear properties of wheel and rail materials with different hardness values
Wear, 2021 This paper aimed to investigate the wear properties of different wheel-rail material pairs with various hardness values. Twin-disc wear experiments were carried out via cross-matching five types of wheel material (ER7, ER8, CL60, C-class and D-class) and

’A Poll Tax on Wheels’: Might the move to Privatise Rail in Britain have Failed? [PDF]
, 2010 Rail privatisation was a controversial, widely unpopular policy whose implementation was not inevitable. This article employs counterfactual history methodology to examine whether the move to rail privatisation in Britain might have failed. It places the

Fully 3D‐Printed Wave‐Wound Electromagnetic Motors
Advanced Materials Technologies, EarlyView.This work presents the first fully 3D‐printed wave‐wound electromagnetic motors, which are created using conductive nanoparticle inks, carbon‐filled nylon polymers, and surface mount components. These motors can achieve a stall torque of 7.62N·mmA−1$7.62 \nobreakspace N{\cdot }mm A^{-1}$ and efficiency of 28.2 %, which approaches the performance of ...

Elbe River Waterway – Economic and Social Benefits
Transactions of the VŠB: Technical University of Ostrava, Civil Engineering Series, 2014 For a very long time the river Labe belongs to the transport ways with an unmistakable impact. Along the river Labe as well as along other inland water ways the commerce was spread and the towns lying on the river of Labe got the state of Hanza towns ...

Waveguide Geometry–Driven Trade‐Offs in Resonant Cavity Sensor Performance
Advanced Optical Materials, EarlyView.Waveguide geometry governs the interplay between sensitivity, intrinsic Q‐factor, and wavelength noise in silicon nitride resonant sensors. Contrary to intuition, higher sensitivity does not ensure superior performance. Low‐noise, high‐Q ridge resonators achieve the lowest detection limits, revealing that detection is ultimately constrained by noise ...

Choice behavior of commuters' rail transit mode during the COVID-19 pandemic based on logistic model
Journal of Traffic and Transportation Engineering, 2020 To understand whether commuters will take rail transit during the COVID-19 pandemic, a logistic regression model was constructed from three aspects of personal attributes, travel attributes and perception of COVID-19 based on 559 valid questionnaires ...

Advanced Robotics Research, EarlyView.This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures
Advanced Robotics Research, EarlyView.Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.
