Noise and Vibration of Resiliently Supported Track Slabs [PDF]
The Journal of the Acoustical Society of America, 1973 In this paper the dynamic response, vibration isolation, and sound radiation of a resiliently supported track slab are analyzed. An analytical model is investigated which views railroad rails as beams fastened elastically to a slab which is resiliently mounted to a substructure. The slab is assumed to be a plate of finite width and infinite length. The

Latitudinal dependence of wind-induced near-inertial energy [PDF]
, 2015 Mid-latitude storms, accounting for the majority of wind energy input to near-inertial motions in the ocean, are known to shift their track significantly from one year to another.

Impermeable membranes for slab-track settlement mitigation [PDF]
Environmental Geotechnics, 2018 A series of numerical simulations is used to explore the effect of the geometrical disposition of impermeable membranes in the overall performance of slab-track railway earthworks, with particular reference to the generation of settlement during several years of exposure to the atmosphere and the admissibility of these post-construction deformations ...

Polarimetry of cosmic gamma-ray sources above e+e- pair creation threshold
, 2013 We examine the potential for gamma-ray conversion to electron-positron pairs, either in the field of a nucleus or of an electron of a detector, to measure the fraction P of linear polarization of cosmic gamma sources.

The need and benefit of slab track: case of Lithuania
Građevinar, 2017 Slab track structures have been used in the world for several decades now. However, the ballasted track is still much more popular compared to slab track structures, which is primarily due to its lower price. This article reviews and analyses development
