Mitambo, Mitambo M., Zhang, Shuliang L., Loppnow, Glen R.
A novel four nuclear magnetic resonance (NMR)-tube holder is described for quantitative Raman and resonance Raman spectroscopy. This cell has advantages over other divided cell designs in producing high precision quantitation and eliminating off-axis errors. Raman spectra were obtained for both...

Amirian, B., Li, H.Y., Hogan, James D.
In this paper, a microstructure-based finite element model for nano-grained (!+↵2)-TiAl/Al2O3 cermets is proposed based on a modified variational formulation of the Gurson model for an elastic-plastic porous material. In the modeling approach, the high volume fraction of alumina, variability in...

Applications of nonautonomous infinite-dimensional systems control theory for parabolic PDEs
DownloadFall 2013
Parabolic partial differential equations (PDEs) are used as models of transport-reaction phenomena in a variety of different industrial chemical and materials engineering processes, and can yield precise descriptions of process variables with complex temporal and spatially dependent system...

Major, Paul W., Melenka, Garrett W., Carey, Jason P., Nobes, David S., Heo, Giseon, Lacoursiere, Ryan A.
Orthodontic torque expression is the result of axial rotation of rectangular archwires within a rectangular bracket slot. This study investigates the effect of bracket material on torque expression. Torque exerted by a rotating archwire on each bracket will be measured as well as the relative...

Forst, Darren, Nijjar, Simrit, Flores-Mir, Carlos, Carey, Jason, Secanell, Marc, Lagravere, Manuel
The objective of this study is to analyze a set of previously developed and proposed image segmentation protocols for precision in both intra- and inter-rater reliability for in vivo tooth volume measurements using cone-beam computed tomography (CBCT) images. Six 3D volume segmentation procedures...

Contributions and challenges of cross-national comparative research in migration, ethnicity and health: insights from a preliminary study of maternal health in Germany, Canada and the UK
Download2011
Friedrich, J., Reime, B., O'Brien, B., Gerrish, K., Bharj, K., Higginbottom, G.M.A., Foster, C., Chowbey, P., Mumtaz, Z., Salway, S.
Background: Public health researchers are increasingly encouraged to establish international collaborations and to undertake cross-national comparative studies. To-date relatively few such studies have addressed migration, ethnicity and health, but their number is growing. While it is clear that...

Lo, Calvin, Sano, Tomoko, Hogan, James D.
We investigated the uniaxial compressive behavior of damaged and intact alumina using quantitative X-ray computed tomography (XCT) analysis coupled with digital image correlation (DIC) for mechanical characterization. Internal three-dimensional crack characteristics such as crack surface area and...

Examination of Braided Composite Geometric Factors Using Three Dimensional Digital Image Correlation Measurement Techniques
DownloadFall 2012
The objective of this thesis is to develop and validate an optical measurement tool for composite braided structures and use this tool to examine important variables, braid radius and angle, under tensile loading and to perform initial studies. Current deformation measurement techniques used on...
