Dynamic performance of low vibration slab track on shared high-speed passenger and freight railway

Transport, 2018
This work investigates dynamic performance of a low vibration slab track on a shared high-speed passenger and freight railway, and an optimal modulus of the isolation layer (rubber pad) is proposed to meet the adaptability of the track system under the ...

The multilevel trigger system of the DIRAC experiment [PDF]

, 2002
The multilevel trigger system of the DIRAC experiment at CERN is presented. It includes a fast first level trigger as well as various trigger processors to select events with a pair of pions having a low relative momentum typical of the physical process ...

Modelling rail corrugation with specific-track parameters focusing on ballasted track and slab track [PDF]

Vehicle System Dynamics, 2011
The objective of this paper is to compare 3 types of track (high performance ballasted track, STEDEF and AFTRAV) from the corrugation growth point of view. This work has considered different vehicle speeds and track radii, and the results have taken into account the four wheels of a bogie.

Study on the threshold for superposed deformation of simply supported bridge creep and track slab upwarp in high-speed railway

Advances in Mechanical Engineering, 2022
Based on long-term inspection data about track geometric irregularity of 32 m-span simply supported girder bridge in China Railway High-Speed for nearly 10 years, it is found that there is continuous periodic track longitudinal level (TLL) with different

Minimal models for topological Weyl semimetals [PDF]

, 2016
Topological Weyl semimetals (TWS) can be classified as type-I TWS, in which the density of states vanishes at the Weyl nodes, and type-II TWS where an electron and a hole pocket meet with finite density of states at the nodal energy.

Tracking slab surface temperatures with electrical conductivity of glaucophane [PDF]

Scientific Reports, 2021
AbstractSlab surface temperature is one of the key parameters that incur first-order changes in subduction dynamics. However, the current thermal models are based on empirical thermal parameters and do not accurately capture the complex pressure–temperature paths of the subducting slab, prompting significant uncertainties on slab temperature ...

Temperature control in molecular dynamic simulations of non-equilibrium processes [PDF]

, 2010
Thermostats are often used in various condensed matter problems, e.g. when a biological molecule undergoes a transformation in a solution, a crystal surface is irradiated with energetic particles, a crack propagates in a solid upon applied stress, two ...

Quality of Slab Track Construction – Track Alignment Design and Track Geometry [PDF]

Civil and Environmental Engineering, 2015
Abstract The slab track superstructure design (without ballast) is a perspective construction especially for building tunnels and bridges in the modernized sections of railway tracks in Slovakia. Monitoring of the structure described in this article is focused on the transition areas between standard structure with ballast and slab ...
