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

Infrastructures, 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.

Anomalous fermion number nonconservation: Paradoxes in the level crossing picture [PDF]

, 2006
In theories with anomalous fermion number nonconservation, the level crossing picture is considered a faithful representation of the fermionic quantum number variation.

Level-Crossing Optogalvanic Spectroscopy

Le Journal de Physique Colloques, 1983
Optogalvanic spectroscopy is applied to the detection of level -crossings at zero and finite magnetic fields. The method provides a sensitive, Doppler-free technique for determining hyperfine structures in both lower and upper levels of atomic transitions.

The Born Oppenheimer wave function near level crossing [PDF]

, 2000
The standard Born Oppenheimer theory does not give an accurate description of the wave function near points of level crossing. We give such a description near an isotropic conic crossing, for energies close to the crossing energy. This leads to the study

Towards improving sustainability of rail transport by reducing traffic delays at level crossings: A case study for the State of Florida

Cleaner Logistics and Supply Chain, 2021
Rail transport makes a significant contribution to the economy of many geographical locations around the globe. Along with numerous merits, rail transport has some demerits as well, such as traffic delays and safety issues at level crossings.

Integrability and level crossing manifolds in a quantum Hamiltonian system [PDF]

, 1998
We consider a two-spin model, represented classically by a nonlinear autonomous Hamiltonian system with two degrees of freedom and a nontrivial integrability condition, and quantum mechanically by a real symmetric Hamiltonian matrix with blocks of ...
