Global k-Level Crossing Reduction

open access: yesJournal of Graph Algorithms and Applications, 2011
Directed graphs are commonly drawn by a four phase framework introduced by Sugiyama et al.in 1981. The vertices are placed on parallel horizontal levels.

Level crossings as bottlenecks [PDF]

open access: yesVojnotehnički Glasnik, 2000
Level crossings represent bottlenecks from the aspect of vehicle capacity as one of basic parameters for traffic flow. From the railway traffic aspect they represent weak points on railway tracks due to rails exposure to the dynamic influence of road ...

On the Joint Distribution of Excursion Duration and Amplitude of a Narrow-Band Gaussian Process

open access: yesIEEE Access, 2018
The probability density of crest amplitude and duration that exceeds a given level is used in many theoretical and practical problems in engineering that are subjected to fluctuating loads such as wind and wave loads.

Landau–Zener tunneling in multiferroic composites

open access: yesNew Journal of Physics, 2015
For a coupled ferroelectric/ferromagnetic composite we demonstrate theoretically a mechanism for ferroelectric–ferromagnetic excitation conversion. The switching occurs upon sweeping an external homogeneous magnetic field that modifies the spectrum.

Investigation of Traffic Safety Situation at the Level Crossings in Lithuania

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2013
Traffic safety assurance is the main task on roads as well as railways. At the level crossings both infrastructures cross each other. Therefore the problem of assuring the traffic safety at the level crossings remains permanently actual and is often ...

Evaluating Pedestrian and Cyclist Behaviour at a Level Crossing

open access: yesTransactions on Transport Sciences, 2020
The article gives an overview about the results of the use of a newly developed measurement technique in order to analyse the behaviour of road users at level crossings.

Crossing Levels: Meta-induction and the Problem of Induction

open access: yesPhilosophy of Science, 2023
AbstractGerhard Schurz claims to have a solution to Hume’s problem of induction based on results from machine learning concerning meta-induction. His argument has two steps. The first is to establish a justification for following a certain meta-inductive strategy based on its predictive optimality.

Prediction of Fatalities at Northern Indian Railways’ Road–Rail Level Crossings Using Machine Learning Algorithms

open access: yesInfrastructures, 2023
Highway railway level crossings, also widely recognized as HRLCs, present a significant threat to the safety of everyone who uses a roadway, including pedestrians who are attempting to cross an HRLC.
