Investigation of the Influences of Track Superstructure Parameters on Ballasted Railway Track Design

The main design criteria of ballasted railway tracks include rail deflections, rail bending stresses, rail wheel contact stresses, sleeper bending moments and ballast sleeper contact pressures. Numerous criteria have been defined for the design of ballasted railway tracks owing to the various mechanical properties of track components and their complex interaction. Therefore, railway track desig...

Design of an ergonomic ultrasound system: accommodation of user anthropometrics.

Long-term use of medical imaging devices requires significant improvements to the user experience. One factor that impact upon such experience is whether the device is ergonomically built, ecologically designed, and leverages the current medical practice. In this research, we took a holistic and systematic approach to design an effective and biomechanically-fit ultrasound system. Research metho...
