Virtual articulation using sequential mandibular intraoral scans and computational functional rotation reference determination—Proof‐of‐concept

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Virtual articulators require accurate spatial orientation of digital casts for meaningful occlusal analysis during prosthesis design. Current methods for establishing this orientation rely on facial scanning, cone‐beam computed tomography, electronic jaw tracking, or arbitrary population–based values. This proof‐of‐concept technique presents a

An investigation into multi-domain simulation for a pantographcatenary system

open access: yesITM Web of Conferences, 2017
There is a need for modelling various phenomena present in a pantograph-catenary structure, (e.g. wave propagation and its reflections, friction, aerodynamic and electromagnetic forces), which allows for a more reliable study on the dynamic behaviours of

Aerodynamic noise from a train pantograph

open access: yes, 2014
Many studies have shown that when the speed of high speed trains exceeds around 300km/h, aerodynamic noise becomes the most significant noise source. The pantograph, or current collector, is mounted on the top of the train and is therefore not shielded ...
