This thesis reports the effects that the scattering and absorption of photons have on the ability to produce tomographic images of an internal gamma-ray source distribution. Computer simulations of the photon-transport ...

Conventional 3-D external beam radiation therapy for breast cancer, although a vast improvement over traditional therapy, does not take into account respiratory motion. With breast cancer patients, this motion can expose ...

The risk reduction potential of the class of artificial neural networks based on the Barto-Sutton architecture is established. The risk associated with nuclear power operations is characterized by sequences of discrete ...

The PMNIM is then used to study the transition to turbulence in Arnold-Beltrami-Childress (ABC) flows. These flows display the interesting phenomenon of heteroclinic cycles. The results are obtained for two wavenumbers: k ...

Pu(VI) speciation and solubility with phosphate was examined at pH from 0.3 to 12.2, Pu(VI) concentrations from 5 $\times\ {\rm 10}\sp{-5}$ M to 1.3 $\times\ {\rm 10}\sp{-3}$ M and phosphate concentrations up to 0.6 M. ...

High-volume air samplers were used to collect aerosol samples on Whatman 41 air filters at the Canadian air sampling stations Burnt Island, Egbert and Point Petre. Once collected, the samples were analyzed for trace elements ...

Inertial-Electrostatic Confinement (IEC) is an alternative approach to fusion power that offers the ability to burn advanced fuels like D-He$\sp3$ in a non-Maxwellian, high density core. These aneutronic reactions are ideal ...
