Applied Sciences, 2023 Switches and crossings (S&Cs) are also known as turnouts or railway points. They are important assets in railway infrastructures and a defect in such a critical asset might lead to a long delay for the railway network and decrease the quality of service.

Applied Sciences, 2020 Track settlement is a common problem observed in ballasted railway tracks. The ballast bed and the material layers underneath it, deform under repeated trainloads and create uneven support conditions along the track. In some cases, the ballast settlement

Simplified Damage Assessment Tool for Rails and Crossings Based on Standard Wear and RCF Models
Metals, 2022 A numerical tool is proposed to simultaneously assess various damage mechanisms that are driven by contact loading. The tool transfers loads to the contact-patch level using three contact parameters: the maximum contact pressure (pmax), the creepage (c ...

Bi-Directional Benes With Large Port-Counts and Low Waveguide Crossings for Optical Network-on-Chip
IEEE Access, 2021 We propose a new variant of the Benes network using a merge-replace-fold approach. It is to realize a large port-count optical switch with low waveguide crossings. A bidirectional switch is built instead of a unidirectional switch.

Braid-positive Legendrian links [PDF]
, 2006 Any link that is the closure of a positive braid has a natural Legendrian representative. These were introduced in an earlier paper, where their Chekanov--Eliashberg contact homology was also evaluated.

Composites for Timber-Replacement Bearers in Railway Switches and Crossings
Infrastructures, 2017 Recent developments in composite materials have resulted in their pilot adoption in railway industry, such as ‘fibre-reinforced foamed urethane (FFU)’, ‘geopolymer concrete’, ‘recycled polymer’, and ‘CarbonLoc composite’.

Scalable 3D Silicon Optical Switch Based on CLOS Architecture
IEEE Photonics Journal, 2022 To achieve complex functionality with small size, weight and power, photonic integrated circuits (PIC) are expanded from two-dimensional (2D) to three-dimensional (3D). In this paper, a new design for a scalable 3D silicon optical switch is proposed. Key

Visualizing Co-Phylogenetic Reconciliations [PDF]
, 2017 We introduce a hybrid metaphor for the visualization of the reconciliations of co-phylogenetic trees, that are mappings among the nodes of two trees. The typical application is the visualization of the co-evolution of hosts and parasites in biology.

Neural Network-Based Train Identification in Railway Switches and Crossings Using Accelerometer Data
Journal of Advanced Transportation, 2020 This paper aims to analyse possibilities of train type identification in railway switches and crossings (S&C) based on accelerometer data by using contemporary machine learning methods such as neural networks.
