Spring 2015
Gravitational removal of the dense lower lithosphere is proposed to be a fundamental process in continental tectonics. This has been used to explain seismological observations of an abnormally thin lithosphere beneath some regions and evidence for detached lithospheric materials at 100-200 km...

Intrafractional tumour tracking is of considerable interest as a means to minimize the PTV in treating mobile tumours. By utilizing the intrafractional MR imaging feature of linac-MR, this thesis seeks to develop a direct, non-surrogate based intrafractional tumour tracking system, and physically...

Intrinsic Disorder Effects and Persistent Current Studies of YBCO Thin Films and Superconducting Tunnel Junctions
DownloadFall 2009
This thesis studies the intrinsic disorder effects and the transport and magnetic properties of ring-shaped epitaxial thin films and superconducting tunnel junctions (STJs) of the high temperature superconductor YBa$2$Cu$3$O${7-\delta}$. We used an unconventional contactless technique that allows...

Investigating Stress Concentrations near Boreholes in Anisotropic Formations and the Mechanical Behavior of Drilling-induced Tensile Fractures
DownloadFall 2015
With the increasing exploitation of unconventional reservoirs, the demands of implementing geomechanics to improve the exploration and development process have been greater than before. Knowledge of in-situ stresses and rock failure mechanisms is key for building a comprehensive geomechanical...

The structural dynamics of proteins and nucleic acids play a vital role in biochemical reactions. We employed novel optical tweezers to study the programmed -1 ribosomal frameshifting, where the conformational plasticity of a SARS pseudoknot with a bound ligand is shown to be correlated to the...

At radar frequencies, the propagation speeds and attenuations of electromagnetic (EM) waves are controlled by the complex dielectric permittivity. Consequently, the real and imaginary components as well as their variation with frequency are important parameters necessary for properly interpreting...

Investigation of gradient echo MRI for blood vessel imaging and susceptibility-weighted imaging in the human brain
DownloadSpring 2010
Despite the vast myriad of applications and the long way it has come, MRI is still a relatively new field of knowledge with much prospect for more advancement and expansion. This work is mainly concerned with two gradient echo imaging methods which are directly or indirectly related to blood...
