Automated Peak Identification For Time -Of -Flight Mass Spectroscopy, Haijian Chen Jan 2006

Automated Peak Identification For Time -Of -Flight Mass Spectroscopy, Haijian Chen

Dissertations, Theses, and Masters Projects

The high throughput capabilities of protein mass fingerprints measurements have made mass spectrometry one of the standard tools for proteomic research, such as biomarker discovery. However, the analysis of large raw data sets produced by the time-of-flight (TOF) spectrometers creates a bottleneck in the discovery process. One specific challenge is the preprocessing and identification of mass peaks corresponding to important biological molecules. The accuracy of mass assignment is another limitation when comparing mass fingerprints with databases.;We have developed an automated peak picking algorithm based on a maximum likelihood approach that effectively and efficiently detects peaks in a time-of-flight secondary ion …


Uv Cure Kinetics Of Dimethacrylate Thin And Thick Samples, Yuemei Zhang Jan 2006

Uv Cure Kinetics Of Dimethacrylate Thin And Thick Samples, Yuemei Zhang

Dissertations, Theses, and Masters Projects

UV curing is using UV light as the energy source to induce the polymerization of liquid monomers and oligomers to form a solid polymer. Because UV polymerization is fast and energy-saving and a UV curable system has no VOC (volatile organic compound), this new technology has developed rapidly from thin film applications to thick sample applications. In addition, since the UV cure process can be controlled spatially and temporally, it also has an important application to make gradient materials with locally optimized properties. However, most research on UV cure is based on thin film applications, and the cure kinetics of …
