Journal ArticleDOI
A Lagrange-based generalised formulation for the equations of motion of simple walking models.
TL;DR: Using Lagrangian mechanics, a generalised formulation for the EOM of n-link open-loop chains is derived, which has an advantage over Newton-Euler mechanics in that it is independent of coordinate system and prior knowledge of the ground reaction force (GRF) is not required.
Journal ArticleDOI
Extra patient movement during mammographic imaging: an experimental study.
TL;DR: This research provides a possible explanation to mammography image blurring caused by extra patient movement and proposes a theoretical model to analyse the movement.
Journal ArticleDOI
A systematic procedure to optimise dose and image quality for the measurement of inter-vertebral angles from lateral spinal projections using Cobb and superimposition methods.
TL;DR: Images of suitable quality for laterally assessing spinal conditions using Cobb or superimposition measurements were produced from an effective dose of 0.05 mSv, which is 83% less than the average effective dose used in the UK for lateral thoracic/lumbar exposures.
Journal ArticleDOI
A novel method of using accelerometry for upper limb FES control
TL;DR: A novel approach to using a 3-axis accelerometer to capture body segment angle for upper limb functional electrical stimulation (FES) control by calculating the angle between the accelerometer x-axis and the gravity vector while avoiding poor sensitivity at certain angles and minimizing errors when true acceleration is relatively large in comparison to gravity.
