Integrating Dynamics and Wear Modelling to Predict Railway Wheel Profile Evolution [PDF]
, 2003 The aim of the work described was to predict wheel profile evolution by integrating multi-body dynamics simulations of a wheelset with a wear model. The wear modelling approach is based on a wear index commonly used in rail wear predictions.

Measurement methods and analysis tools for rail irregularities. A case study for urban tram track [PDF]
, 2015 Rail irregularities, in particular for urban railway infrastructures, are one of the main causes for the generation of noise and vibrations. In addition, repetitive loading may also lead to decay of the structural elements of the rolling stock.

When should firms watch for cross‐industry competition? A demand‐side perspective
Strategic Management Journal, EarlyView.Abstract Research Summary Research on competitor identification has primarily focused on intra‐industry competition. However, cross‐industry competitive threats are prevalent and consequential. We adopt a consumer‐oriented perspective to examine how consumer perceptions shape de facto competition across industry boundaries.

Systems Research and Behavioral Science, EarlyView.ABSTRACT George Herbert Mead is an oft forgotten or ignored American philosopher who was one of the originators of pragmatism. Today, he is recognised as a creative thinker who has teased out knotty problems that others in the field had not realised were problems. Understanding Mead's analysis has been made difficult because he died prematurely without
