Track geometry quality assessments for turnouts
Transportation Engineering, 2023 Turnouts are necessary, frequent and cost intensive. Despite the railway sector's focus on automation, the condition assessment of turnouts is still mostly done manually by responsible staff inspecting the turnout.

Performance-based track geometry and the track geometry interaction map
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2008 The track geometry interaction map (TGIM) is proposed as an effective way to evaluate the impact of multiple track geometry parameters on rail safety. Multi-body dynamics software has been used to simulate vehicle performance over tracks containing a large number of randomly generated lateral and vertical track geometry combinations.

Geometry-aware manipulability learning, tracking, and transfer [PDF]
The International Journal of Robotics Research, 2020 Body posture influences human and robot performance in manipulation tasks, as appropriate poses facilitate motion or the exertion of force along different axes. In robotics, manipulability ellipsoids arise as a powerful descriptor to analyze, control, and design the robot dexterity as a function of the articulatory joint configuration. This descriptor
