On the other hand, they may be potentially dangerous as would be the case if vinyl chloride monomer or heavy metals migrated into the food in sufficient quantities. This project will study mathematical models of these migration processes especially those associated with plastic and polystyrene packaging. A pattern is put into the bottom of a moulding box and the box is filled with moulding sand. High- pressure air is used to compact the sand and this forces the sand against the pattern. When the pressure is released, the pattern is separated from the moulded sand leaving a shape, which can be filled with molten metal.
Genomics is the analysis and application of molecular genetic information.
Although there are huge amounts of data being developed in this area, for example for the human genome project and for pharmaceutical industry, the statistical tools for appropriately analysing these data are still being developed. This project will focus on a genomic analysis problem in the livestock industry, in collaboration with a local biotechnology company. Typically, the only way to resolve these PDEs is to employ sophisticated numerical methods. It is the aim of this project to focus on the solution of the nonlinear algebraic system that arises from a finite volume discretisation. A variety of different iterative methods will be analysed and their efficiencies compared for typical problems arising in transport in porous media.
