More and more solid-state magnetic field sensors such as Hall devices are used in eddy current inspection (EC) to acquire magnetic field signals. This work extends the previous analytical model, i.e. 2D Extended Truncated Region Eigenfunction Expansion (ETREE) of EC, and focuses on establishment of 3D ETREE of multi-frequency eddy current inspection (MFEC) on stratified conductors, while taking...

The level set method provides a natural framework for modelling multiphase phenomena in a Eulerian basis. The method is based on the evolution of the signed distance function from interfaces between phases of the flow, and automatically captures complex topological changes of the free surfaces such as breaking and merging. We present an extension to the level set method for modelling the intera...

This paper describes an approach to elastic modelling of human tissue based on the use of 3D solid active models active cubes [2] and a shape description based on the metric tensor in a solid. Active cubes are used because they provide a natural parameterization of the surface and the interior of the given object when deformed to match the object's shape. Using the metric tensor to store the sh...

In this paper, we present a solid-core Silica-based photonic crystal fiber (PCF) composed of hexagonal lattice of air-holes and calculate the effective index and chromatic dispersion of PCF for different physical parameters using the empirical relations method (ERM). These results are compared with the data obtained from the conventional multipole method (MPM). Our simulation results reveal tha...

A high temperature and shear rate capillary viscometer has been designed, constructed and recently commissioned. This device will be used to measure the viscosity of semi-solid metals under the high temperature and shear rate conditions, similar to those found in industry. Design criteria for the device included a requirement for a highly controllable temperature (±1oC) up to 650oC, capability ...

Solid oxide cells are an exciting technology for energy conversion. Fuel cells, based on solid technology, convert hydrogen or hydrogen-rich fuels into electrical energy, with potential applications in stationary power generation. Conversely, electrolysers electricity chemical thereby offering the to store from transient resources, such as wind turbines and other renewable technologies. For dis...

The suitability of a commonly used accumulation and wash-off model for continuous modelling of urban runoff contamination was evaluated based on 11-month turbidity and flow-rate records from an urban street. Calibration and uncertainty analysis were performed using a Markov Chain Monte-Carlo sampling method for both suspended solids loads (discharge rates) and concentration modelling. Selected ...
