IET Cyber-Systems and Robotics, Volume 8, Issue 1, January/December 2026.ABSTRACT Foreign object debris (FOD) detection is critical to aircraft safety, but existing visual algorithms have difficulty in detecting tiny objects and in low‐light conditions. FOD detection in low‐light conditions can be achieved using laser line‐scan cameras, but there is still a lot of room for research on how to better use the multi‐channel ...

Flextural Performance of Ultra-High Performance Concrete Ballastless Track Slabs
, 2016 Ballastless track slab offers excellent stability and durability and has been well accepted in high-speed railways worldwide. Rails are typically laid on precast concrete slabs that are subjected to dynamic load transferred from the rails.

Numerical Analysis of Ballastless Asphalt Tracks Subjected to Dynamic Loads [PDF]
, 2021 This study presented the results of numerical analyses for a ballastless asphalt track. The asphalt layer was modelled as a linear viscoelastic (LVE) solid that was resting on an unbound granular layer (UGL) simulated as a non-linear (stress-state dependent) elastic medium.

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.The mechanism of soil arching is a critical technical issue in the load transfer of geosynthetic‐reinforced pile‐supported (GRPS) embankments. To investigate the evolution of soil arching under high‐speed railway loading within a pile group system, a performance analysis model for a GRPS embankment was established using ABAQUS.

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.Line shape control is the most critical step in the construction of high‐speed railway bridges. The deflection of long‐span bridges (such as cable‐stayed bridges) is more complex as a multipoint elastic‐supported system, especially during track slab construction.

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.Interferometric synthetic aperture radar (InSAR) processing is widely implemented to remotely inspect linear infrastructure, such as railway tracks, enabling a wide range of spatiotemporal coverage. Despite InSAR is nowadays integrated with other remote sensing data and in situ measurements to establish structural health monitoring systems of railway ...

The Service Life of Ballastless Track
Procedia Engineering, 2017 Abstract Before the widespread use of high-speed rail ballastless track needs to be tested in real conditions at high speed and small axial load. Experimental railway track of “VNIIZhT” makes it possible to carry out tests at high axial load, low speed but that does not fully meet the real fields of application of ballastless track.
