Defining gravitational singularities in general relativity
(2008-07-22)Singularities have been a long-standing problem in general relativity. In all other fields of physics, singularities can be easily located and avoided; in general relativity, singularities have an impact on the creation ... -
Design and Fabrication of a Nanocantilever for High-Speed Force Microscopy
(2009-02-02)The atomic force microscope (AFM) has become an important tool in many fields ranging from materials science to biology. The central component of the AFM is a probe consisting of a soft cantilever to which a sharp tip is ... -
Design and Implementation of Tools for STM Studies in UHV and at the Solid-Liquid Interface
(2016-08-11)This thesis presents details of the design and development of novel tools and instruments for scanning tunneling microscopy (STM), and may be considered as a repository for several years' worth of development work. The ... -
Design and Manufacture of a High-Frequency Annular Array Ultrasound System for Medical Imaging
(2011-05-06)This thesis presents the design of a high-frequency annular array ultrasound system suitable for medical imaging. To reduce the cost of the system, off-the-shelf parts were used whenever possible. The system consists of ... -
The Design of a Scanning Tunneling Microscope for Electroluminescence Studies
(2015-12-16)A conventional scanning tunneling microscope (STM) provides topographical and tunneling spectra information of atomic structures. However, the extremely small lateral dimension of the tunneling filament is also responsible ... -
Design of Transparent Conducting Electrodes and Surface Relief Gratings for Plasmonic Polymer Solar Cells
(2016-08-25)As the concept of renewable energy becomes increasingly important in the modern society, a considerable amount of research has been conducted in the field of organic photovoltaics in recent years. Although organic solar ... -
Design, fabrication and characterization of a suspended heterostructure
(2007-09-28)This thesis presents the design and theoretical modeling of an aluminum gallium arsenide/gallium arsenide heterostructure from which suspended nanoscale mechanical resonators with embedded two-dimensional electron gas ... -
A detailed observational analysis of magnetism in three B and O stars observed within the context of the MiMeS project
(2012-09-28)The detailed observational analysis of three massive B- and O-type stars was carried out in this study in order to characterize their fundamental, magnetic, and variability properties. The bulk of the data acquired were ... -
Detector Development and Test Facility Commissioning for SuperCDMS
(2011-06-06)SuperCDMS, the next stage of the Cryogenic Dark Matter Search (CDMS), uses cylindrical germa- nium crystals as particle detectors to measure phonon and ionization signals resulting from particle interactions. The aim of ... -
Developing Single-Laser Sources for Multimodal Coherent Anti-Stokes Raman Scattering Microscopy
(2011-08-11)Coherent anti-Stokes Raman scattering (CARS) microscopy has developed rapidly and is opening the door to new types of experiments. This work describes the development of new laser sources for CARS microscopy and their use ... -
Development of a Novel Readout System for Radiochromic Film Dosimetry
(2014-09-02)As radiation therapy treatment modalities continue to develop, patient dose delivery has become increasingly complex. The verification of dose delivery and the quality assurance (QA) to ensure that a prescribed dose is ... -
Development of Optoelectronic Devices and Computational Tools for the Production and Manipulation of Heavy Rydberg Systems
(2007-10-26)Experimental and theoretical progress has been made toward the production and manipulation of novel atomic and molecular states. The design, construction and characterization of a driver for an acousto-optic modulator is ... -
The Development of the SNO+ Experiment: Scintillator Timing, Pulse Shape Discrimination, and Sterile Neutrinos
(2014-04-29)The SNO+ experiment is a multi-purpose neutrino detector which is under construction in the SNOLAB facility in Sudbury, Ontario. SNO+ will search for neutrinoless double beta decay, and will measure low energy solar ... -
Dissipative dynamics of atomic Bose-Einstein condensates at zero temperature
(2013-04-26)In this thesis we study various dissipative processes that are associated with the flow of an atomic Bose-Einstein condensate at zero temperature. In particular, we investigate the effect of a weak correlated disorder ... -
Domain Boundaries of the 5x5 DAS Reconstruction
(2011-11-11)Steps on surfaces have long been explored for their own sake, and exploited as growth mediators. However, another type of linear surface defect - the domain boundary - has been largely neglected. Here we introduce domain ... -
Dust Dynamics in the Galactic Disk-Halo Vicinity
(2007-09-27)We report on the dynamics of interstellar dust grains above the plane of the Milky Way. Our Galactic model closely matches its large-scale observed properties, namely the luminosity output, the gas content and distribution, ... -
Dyadic Green Functions and their applications in Classical and Quantum Nanophotonics
(2012-04-26)Research in solid-state nanophotonics and quantum optics has been recently pushing the limits in semiconductor microcavity design. High quality microcavities that confine light into small volumes are now able to drastically ... -
Dynamic Made-To-Measure: A Method of Making Dynamically Self-Consistent Triaxial Dark Matter Halos
