Content based image pose manipulation
… symmetry to the wavelet transformed images in an iterative optimisation scheme removes this perspective pose. This advances upon existing spatial approaches that require segmentation and feature matching, and frequency only techniques that are limited to affine transformation recovery. To evaluate …

Monte Carlo solution to the inverse problem of ultrasonic defect characterisation
… Chain Monte Carlo methodology is employed as an iterative optimisation strategy, minimising a cost function between observations and a projected model. Modelled flaw parameters are updated stochastically such that they converge toward the true values over successive iterations. The advantages of …

Whole life costing optimisation with integrated logistics support considerations.
… complex systems with long life-span, the optimisation of maintenance-related activities is important to fulfil system readiness, safety and whole life cost requirements. Modern petroleum equipment like gas turbines and drilling rigs are dependent on readily available maintenance supports …

Surrogate Model Optimisation for PWR Fuel Management
… In this thesis, the method of surrogate model optimisation is adapted to PWR loading pattern generation. Surrogate models are developed based around three approaches: deep learning methods (convolutional neural networks and multi-layer perceptrons), the fission matrix and simulated quantum …
