Full waveform inversion of ultrasonic phased array data for the tomographic reconstruction of heterogeneous media for NDT
… reversible jump Marko chain Monte Carlo method (rj-MCMC), to perform the tomographic reconstruction in the form of a posterior distribution. The reconstructed wave speed maps are then used in conjunction with an imaging algorithm (TFM), to provide enhanced flaw imaging. The quality of the imaged …

Reconstructing spatially heterogeneous thermal maps using light-based metrology sensors
… reversible jump Markov Chain Monte Carlo method (rj-MCMC), is then used as the optimisation method in the inversion. Using the recovered refractive index map led to improvements in discounting the refractive effects by up to 54 % and the uncertainty of this positioning problem was reduced by up to …

Monte Carlo Methods in Practice and Efficiency Enhancements via Parallel Computation
… approaches such as Markov chain Monte Carlo (MCMC) and sequential Monte Carlo (SMC) can be endlessly adapted to tackle the most complex problems. What is important then is to construct efficient algorithms, and significant attention in the literature is devoted to developing algorithms that …
