CALCULATION OF THE EQUIVALENT CONICITY FUNCTION OF THE RAILWAY WHEELSET TREAD PROFILE AT THE DELTA R FUNCTION WITH A NEGATIVE

Calculation of the Equivalent Conicity Function of the Railway Wheelset Tread Profile at the Delta R Function with a Negative

The rail-wheel interface is fundamental to explain the dynamic running behaviour of a railway vehicle.It must therefore be understood and among the parameters by which it is characterised, the one called "equivalent conicity" plays an essential role since it allows the satisfactory appreciation of the wheel-rail contact on tangent track and on larg

Value increase of jetty project based on system dynamics

Waste or additional costs in infrastructure projects such as jetty projects are often caused by rework.Besides having an impact on costs, rework is also a very significant contributor to waste or adding time which causes delays in the completion schedule of the project.A lot of research on rework has been carried out on both building and road const

Can mergers-in-progress be unmerged in speech accommodation?

This study examines spontaneous phonetic accommodation of a dialect with distinct categories by speakers who are in the process of merging those categories.We focus on the merger of the NEAR and SQUARE lexical sets in New Zealand English, presenting New Zealand participants with an unmerged speaker of Australian English.Mergers-in-progress are a un
