Fall 2021
The purpose of this dissertation is to generate better solutions for the existing problems in the wireless communications and navigation systems by designing antennas with special characteristics such as circular polarization (CP), tilted beam, transparency, high gain, front to back ratio (FBR)...

Transparent transducers and fast electronics for next-generation ultrasound and photoacoustic imaging
DownloadSpring 2022
Most ultrasound transducers are opaque. Transparent transducers could lead to novel applications, including combined optical and ultrasound imaging, photoacoustic imaging and other multi-modality systems. This thesis introduces transparent capacitive micromachined ultrasound transducers and...

Transpiration Response of Residual Lodgepole Pine After Partial-cut and Strip-shelterwood Harvesting in Alberta's Southern Rocky Mountains
DownloadFall 2019
Forest harvesting reduces forest canopy cover which can reduce evapotranspiration and affect the hydrologic regime of watersheds. Prior research has shown while transpiration is reduced by the removal of trees, it can also affect soil moisture and meteorological variables (e.g....

Transplant Tourism: An International and National Law Model to Prohibit Travelling Abroad for Illegal Organ Transplants
DownloadFall 2017
Transplant tourism, a term used to describe travelling for transplantation if it involves practices such as organ commercialization, organ trafficking and the neglect of the transplant needs of individuals in the destination/transplant State, is currently a global concern. Accounting for about...

Transport and deposition of particles onto homogeneous and chemically heterogeneous porous media geometries
DownloadFall 2011
Particle transport and deposition in porous media are central to a wide gamut of natural and engineering processes. In order to establish optimal macroscopic performance, it is essential to understand the microscopic colloid transport fundamentals that ultimately manifest at the macroscopic...

Fall 2019
This thesis provides a theoretical discussion of several new phenomena associated with spin-orbit coupling in systems that lack inversion symmetry. Chapter 1 gives an introduction to the context of spin-orbit coupling in condensed matter physics and the role of inversion symmetry breaking. The...

Transport and Transfer of Total Dissolved Gases in the Lower Columbia River Hydropower System
DownloadSpring 2020
Hydropower facilities can generate elevated or supersaturated total dissolved gases (TDGs) during spill operations that can impose environmental and ecological risk to downstream habitat, particularly to fishes causing gas bubble disease and mortality. Assessment of such impact and management of...

Fall 2019
In hydraulic fracturing, resin-coated ceramic proppants can be added to fracturing fluid as an agent for propping the fractures. Resin-coated ceramic proppants have several advantages compared to the traditional silica sands and ceramic proppants. Resin-coated ceramic proppants can withstand much...
