Evaluation Of Stepwise Spectral Unmixing With Hydice Data, Daniel Newland

Theses

Images of ground scenes have a tradeoff between spatial and spectral resolution. Sensors with fine spectral resolution sacrifice high spatial resolution. A hyperspectral image has tens to hundreds of bands of spectral information, which can potentially be used to increase understanding of the spatial content of a scene despite resolution limitations. While some pixels in an image could be identified as "trees" or "roads," for example, a number of pixels will be mixed, containing two or more material classes. The process called unmixing calculates the fractional presence of those predetermined materials. A new statistics-based stepwise unmixing routine has recently been …

Simulation Of Spectra Signatures Of Chemical Leachates From Landfills, Jason Hamel

Theses

Chemical leachates from landfills can turn into dangerous hazards if they are not identified and properly disposed. Currently, these chemicals are identified in the laboratory with samples hand collected from contaminated sites. This is economical for small sites but quickly gets expensive and time consuming for larger facilities that can cover hundreds of acres or multiple sites. This study examines the feasibility of using new hyperspectral detectors and computer processing to autonomously identify the presence of these leachates and greatly simplifying the monitoring process for these large sites. The effect of even low concentrations of many chemicals requires the identification …

New Polyether Toxins From Shellfish And Marine Phytoplankton: Isolation Studies And Development Of Analytical Methods, Alan G. Bishop

Characterisation And Optimisation Of Gypsum Crystallization, Catherine H. Shannon

Theses

Gypsum is produced as a by-product during the citric acid production process at ADM Ringaskiddy. The particle size and filterability of the gypsum has a critical bearing on the overall citric acid production rate. Prior to August 1996, research in the area of gypsum crystal optimisation at ADM had concentrated on the application of vortex mixing to perform the gypsum formation reaction. While the gypsum crystals produced with vortex mixing were found to be desirably clear of microcrystalline gypsum, the crystals were considerably smaller and more difficult to filter and wash. This research project sought to retain the advantages conferred …
