Dynamic effect of high speed railway traffic loads on the ballast track settlement [PDF]
, 2011 The traditional ballast track structures are still being used in high speed railways lines with success, however technical problems or performance features have led to non-ballast track solution in some cases.

Wheel–rail contact: experimental study of the creep forces–creepage relationships [PDF]
, 2014 The wheel–rail contact problem plays an important role in the simulation methods used to solve railway dynamics problems. As a consequence, many different mathematical models have been developed to calculate wheel–rail contact forces.

Finite Difference Dynamic Analysis of Railway Bridges Supported by Pasternak Foundation under Uniform Partially Distributed Moving Railway Vehicle [PDF]
, 2015 Rail transport has experienced great advances in recent times, characterised by increasing high speed and weights of railway vehicles. The vibration and dynamic stress being subjected to by the transport structures, such as road or railway bridges, have ...

Map++: A Crowd-sensing System for Automatic Map Semantics Identification
, 2015 Digital maps have become a part of our daily life with a number of commercial and free map services. These services have still a huge potential for enhancement with rich semantic information to support a large class of mapping applications. In this paper,

Wear rates in urban rail systems [PDF]
, 2017 A significant part of maintenance costs in urban rail systems (metro, tram, light rapid transit/light metro) is due to wheel-rail wear. Wear rates - measured for example as depth of wear per kilometre run (rolling stock) or per train passage (rails ...

Lobbying and Political Risk Disclosure: Do Socially Responsible Firms Voluntarily Disclose More?
British Journal of Management, EarlyView.Abstract Drawing on theories of strategic communication, legitimacy, impression management and moral capital, this study investigates whether firms use political risk disclosure to offset negative perceptions associated with corporate lobbying. Using a sample of 10,120 observations from 1362 US firms between 2002 and 2018, we find that firms with ...

A comparison of bearing life in new and refurbished railway axle boxes [PDF]
, 2001 A simple linear dynamical model shows that at normal running speeds of freight wagons, forced oscillations due to periodic track compliance are transferred to the overlying unsprung mass and significantly amplified. Due to these oscillations, a small gap
