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...

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...
