Diffusing wave spectroscopy applied to material analysis and process control
… relies on the concept of the diffusive migration of light, as opposed to the ballistic scatter model used in conventional dynamic light scattering. The specific requirements of the optoelectronic hardware, data analysis methods and light scattering model were studied …

Long-Term Performance of HDPE Geomembranes as Landfill Liners
… of the aged HDPE geomembrane on the migration of volatile organic compounds (VOCs) was examined by conducting diffusion and partitioning tests using both unaged and aged HDPE geomembranes. The results showed that the ageing of HDPE geomembranes did not increase diffusive migration of …

Planetesimal and Protoplanet Dynamics in a Turbulent Protoplanetary Disk
… disk, planetary objects undergo orbital migration due to the gravitational torques exerted by their surrounding gas. It has been an outstanding issue that an earth-sized planet embedded in a gas-rich environment may rapidly migrate into its host star. In this dissertation, I study some of …

The role of colloidal organic matter in the marine geochemistry of PCB’s
… sediment transport model was evaluated. Enhanced migration of highly sorbed PCBs can be included in an apparent diffusivity term when steady-state conditions exist. Model calculations showed that diffusive migration of PCBs in typical coastal sediments is minor over 20 yr timescales. Comparisons …
