A longer service life of intermediate elastic fastenings KPP-5 due to application of pads PRP-3.2
MATEC Web of Conferences, 2018 Since 2003 Ukrainian railways have used KPP-5 intermediate elastic fastenings. These fastenings unlike their predecessors (for example, terminal-bolted fastenings (KB) widely used on railways), first of all, have fewer elements.

MATEC Web of Conferences, 2017 At present, the most common track model is the one in which rails are presented as bars of infinite length rested on continuous elastic foundation. However, some specialists consider the model to be rather ideal for railways in terms of track and the ...

Calculating track thrust with track functions [PDF]
Physical Review D, 2013 In e+e- event shapes studies at LEP, two different measurements were sometimes performed: a "calorimetric" measurement using both charged and neutral particles, and a "track-based" measurement using just charged particles. Whereas calorimetric measurements are infrared and collinear safe and therefore calculable in perturbative QCD, track-based ...

Ship Target Identification via Bayesian-Transformer Neural Network
Journal of Marine Science and Engineering, 2022 Ship target identification is of great significance in both military and civilian fields. Many methods have been proposed to identify the targets using tracks information. However, most of existing studies can only identify two or three types of targets,

Mitigating the Goldilocks effect: the effects of different substrate models on track formation potential [PDF]
Royal Society Open Science, 2014 In ichnology, the Goldilocks effect describes a scenario in which a substrate must be ‘just right’ in order for tracks to form—too soft, the animal will be unable to traverse the area, and too firm, the substrate will not deform.
