Dynamic optimization of track components to minimize rail corrugation [PDF]

, 2009
In this paper, the influence on corrugation of the most significant track parameters has been examined. After this parametric study, the optimization of the track parameters to minimize the undulatory wear growth has been achieved. Finally, the influence

Influence of Sleeper Distance on Rail Corrugation Growth

, 2018
Rail corrugation is commonly found in most railway tracks worldwide. However, there is no solution to stop corrugation from growing. Therefore, to minimise corrugation growth, this paper aims to model, analyse, and predict rail corrugation growth under ...

Engineering Borophene Band Structure Through Thickness

Advanced Science, EarlyView.
Borophene grown on W(110) shows a thickness‐dependent evolution of its structural and electronic properties. Surface microscopy, diffraction, XPS, and ARPES reveal distinct monolayer and bilayer phases. The formation of the second layer is accompanied by structural reconstruction, changes in chemical properties, and new ARPES features, demonstrating ...

Analysis of Human Head Interaction in Handset Antennas Using Ground Plane Corrugation

IEEE Access
This paper presents a novel approach for designing a mobile antenna with a Low Specific Absorption Rate (SAR). First, the relationship between the electric field and the SAR value is constructed based on the Poynting Theorem studied in the near-field ...

Site Density Governs Switching Reactivity Regimes During Aerobic C─H Oxidation in Mn Single‐Atom Photocatalysts

Angewandte Chemie, EarlyView.
Increasing the density of isolated manganese (Mn) atoms in carbon nitride (CNx) photocatalysts does not continuously improve performance. Instead, beyond a critical loading, the polymer support reorganizes, altering charge‐carrier dynamics and oxygen activation while preserving atomic dispersion.
