Automated tracking and classification of the settlement behaviour of barnacle cyprids [PDF]
Journal of The Royal Society Interface, 2017 A focus on the development of nontoxic coatings to control marine biofouling has led to increasing interest in the settlement behaviour of fouling organisms. Barnacles pose a significant fouling challenge and accordingly the behaviour of their settlement-stage cypris larva (cyprid) has attracted much attention, yet remains poorly understood.

Geotecnia, 2023 Railway track transition zones are characterised by an abrupt change in track support stiffness, which increases dynamic wheel loads and leads to the acceleration of differential settlement and track degradation.

Wheel–Rail Impact Loads and Track Settlement in Railway Crossings [PDF]
, 2019 Turnouts (Switches & Crossings, S&C) are critical components of a railway track requiring regular maintenance and generating high life cycle costs. A main driver for the high maintenance costs is the need to repair and replace switch rails and crossings as these components are subjected to a severe load environment.

Energy Reports, 2023 Subway tunnel construction often crosses existing railways, and the soil loss caused by shield construction will inevitably lead to deformation of the surrounding strata and uneven settlement of the adjacent railway tracks, but there are few studies on ...

Vibration of different types of tracks of subway in soft soil
Yantu gongcheng xuebao, 2017 The settlement of subway tunnel due to the rail load after its construction has cause wide concern. But the report of dynamic characteristics of railroad considering uneven settlement has not been reported.

Settlement analysis using a generic ballasted track simulation package [PDF]
, 2019 Uneven track settlement inevitably occurs for ballasted track and eventually results in poor track geometry and support stiffness leading to considerably high maintenance cost.

Coloring coral larvae allows tracking of local dispersal and settlement
PLOS Biology, 2022 Quantifying patterns of dispersal and settlement in marine benthic invertebrates is challenging, largely due the complexity of life history traits, small sizes of larvae (<1 mm), and potential for large-scale dispersal (>100 km) in the marine environment.

Influence and Control Strategy for Local Settlement for High-Speed Railway Infrastructure
Engineering, 2016 This paper discusses the main impact factors of the local settlement and differential settlement of high-speed railway lines. The analysis results show that groundwater exploitation is the direct cause of differential settlement.
