Artificial Intelligence Enabled Road Vehicle-Train Collision Risk Assessment Framework for Unmanned Railway Level Crossings

IEEE Access, 2020
The study focuses on the artificial intelligence empowered road vehicle- train collision risk prediction assessment, which may lead to the development of a road vehicle-train collision avoidance system for unmanned railway level crossings.

Seismic analysis and design of tunnels within fault ground: A review

Deep Underground Science and Engineering, EarlyView.
The research methods of seismic response of tunnels within fault ground, including field investigations, analytical solutions, physical experiments, and numerical simulations, and seismic countermeasures are discussed. The present study examines the shortcomings and limitations of the current research and design, and puts forward proposals for future ...

Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Regeneration failure, fire, topography, and climate interact to drive temperate wet forest landscapes into fire traps

Ecography, EarlyView.
Where early successional forests are more flammable than old‐growth forests, forested landscapes are vulnerable to shifting into ‘fire traps' through positive feedbacks, where fire leads to more fire. These feedbacks are amplified by increased flammability driven by climate change, the presence of non‐native flammable plant species, and slowed ...

How safe is safe enough? : a socio-technical view of low-cost level crossing safety [PDF]

, 2013
Low-cost level crossings are often criticized as being unsafe. Does a SIL (safety integrity level) rating make the railway crossing any safer? This paper discusses how a supporting argument might be made for low-cost level crossing warning devices with ...

Actinide 4,4′‐Bipyridine‐N,N′‐Dioxide Coordination Polymers: Cationic Framework Structures Templated by Dicyanoaurate and Tetracyanoaurate Counterions

European Journal of Inorganic Chemistry, EarlyView.
Th4+ or UO22+ actinides, neutral bipyridine‐N,N’‐dioxide ligands, and anionic cyanoaurate linkers are combined to generate a family of four coordination polymers. ‘Truss bridge’ and square grid cationic frameworks are yielded when using [Au(CN)2]− or [Au(CN)4]−, respectively, indicating a templating effect guided by either aurophilic interactions ...
