Improved tractography using asymmetric fibre orientation distributions

Diffusion MRI allows us to make inferences on the structural organisation of the brain by mapping water diffusion to white matter microstructure. However, such a mapping is generally ill-defined; for instance, diffusion measurements are antipodally symmetric (diffusion along x and -x are equal), whereas the distribution of fibre orientations within a voxel is generally not symmetric. Therefore,...

NDT characterisation of carbon-fibre and glass-fibre composites using non-invasive imaging techniques

The prerequisite for more competent and cost effective transport has led to the evolution of innovative testing and evaluation procedures. Non-destructive testing and evaluation (NDT & E) techniques for assessing the integrity of composite structures are essential to both reduce manufacturing costs and out of service time of transport means due to maintenance. Smart methods for assessing the in...

Fatigue behaviour of short fibre reinforced polyamide: morphological and numerical analysis of fibre orientation effects

The fatigue behaviour of injection moulded short fibre reinforced polymers depends upon fibre orientation, as shown in experiments conducted with notched specimens injected through different injection gates. The different fatigue behaviour is related to the different local elastic properties, as determined by the different fibre orientation patterns, resulting into different strain distribution...
