Sampling combinatorial energy landscapes by classical and quantum computation
Combinatorial and, by extension, non-convex optimization problems are among the most difficult to solve computationally due to the inadequacy of local search methods alone to find global optima. The notion of an energy ... -
Mathematical modeling of glucose and insulin dynamics in adolescent girls to quantify measures of insulin sensitivity
The regulation of plasma glucose is a key component of human metabolism and is largely regulated by insulin that facilitates glucose uptake by tissues. When tissues become more resistant to insulin, glucose concentrations ... -
Functional resilience evaluation of road tunnels through stochastic event simulation and data analysis
Resilience of tunnels can have significant impact on the efficiency of the entire transportation network. The ability to assess resilience of tunnels accurately is important for tunnel owners and stakeholders when they ... -
Hydrate film growth and risk management in oil/gas pipelines using experiments, simulations, and machine learning
The formation of gas hydrates in oil and gas flowlines is considered a major flow assurance (FA) issue due to hydrate blockage forming within minutes to hours. Traditionally, hydrate formation was prevented in oil and gas ... -
Multi-scale microscopy of the Li/electrolyte interface in solid-state next-generation batteries
The transition to renewable energy sources is dependent on the availability of sufficient storage. To meet these urgent demands, scientists are racing to find new battery chemistries and architectures One of the promising ... -
Study of excited halo states in ¹⁰Be and ¹²Be using one-neutron transfer reactions from ¹¹Be on ⁹Be at TRIUMF ISAC-II
The structures of beryllium isotopes display a complex interplay between Shell Model and cluster configurations. From ${}^{8}\mathrm{Be}$ on, the structures of Be isotopes is expected to be built on the $\alpha-\alpha$ ... -
Wideband antennas with polarization diversity for wireless applications
The rapid growth of our wireless system infrastructure has created an environment that numerous devices communicate in close proximity, sometimes even in co-located positions. In addition, data rates in communication systems ... -
Separation of trivalent actinides and lanthanides with sulfur donor ligands and extractants
The separation of trivalent actinides and lanthanides in the processing of used nuclear fuel is challenging due to the similar sizes, charges, and redox properties of the two classes of metals. Typical separations procedures ... -
Effects of austenite conditioning on microstructural development and interphase precipitation in titanium-molybdenum microalloyed steels, The
A challenge exists in the automotive industry to develop new, hot-rolled, microalloyed steels offering a balance of high tensile strength and superior stretch-flange formability. The steel industry has responded by developing ... -
Numerical investigation of the perforation friction loss, coefficient of discharge and erosional processes during limited entry hydraulic fracturing treatments
Hydraulic fracturing is behind the successful and feasible exploitation of unconventional hydrocarbon resources around the world. Pioneered by North American operators, the multi-stage massive treatments have enabled ... -
Linking morphology to electronic properties in small-molecular organic semiconductors
In organic electronics, morphology inevitably affects important device properties. The understanding of these relationships and ultimately control of morphology in small-molecular organic materials is necessary for their ... -
Characterizing the excavation process associated with removal of shotcrete reinforced underground structural liners using waterjet technology
The primary objective of this research is to characterize the operating parameters and fragmentation mechanisms associated with the hydroexcavation of reinforced shotcrete and concrete liners used in underground mines and ... -
Application of machine learning to gas flaring
Currently in the petroleum industry, operators often flare the produced gas instead of commodifying it. The flaring magnitudes are large in some states, which constitute problems with energy waste and CO\textsubscript{2} ... -
Porphyry and skarn deposits of the Chillagoe mining district, northeast Queensland, Australia, The
The Chillagoe mining district is located in northeast Queensland and hasintermittently produced zinc, lead, silver, copper and gold from porphyry, skarn and carbonate replacement deposits since 1888. To understand the ... -
Submarine canyons, channels, levees, and lobes: an investigation of the linkages between depositional processes, stratigraphy, and sedimentology
Continental margin depositional systems are of great importance to science and society in that their deposits are an important record of earth history and host valuable natural resources. Submarine fans form the largest ... -
X-ray photoelectron spectroscopy investigation of surfaces and interfaces in fuel cell applications
Advanced characterization methods play a central role in materials development, from initial exploratory synthesis to the testing and validation stage. A particularly powerful technique widely employed to identify ... -
Universal observable chemical bond analysis: gradient bundle decomposition of the electron charge density
Our curiosity-driven desire to "see" chemical bonds dates back at least one-hundred years, perhaps to antiquity.Sweeping improvements in the accuracy of measured and predicted electron charge densities, alongside our largely ... -
Protonic ceramics for electrochemical hydrogen compression
The topic of this thesis is designing and characterizing protonic ceramics for the electrochemical hydrogen compression. Protonic-ceramic reactors are attractive for compressed hydrogen production from natural gas because ... -
Surface interactions and locked cycle flotation of novel collectors on bastnäsite ore
Flotation of a bastnäsite containing ore with novel collectors was investigated using locked cycle froth flotation. Previous research into the flotation of bastnäsite ore simply considered single stage flotation and while ... -
Improving plastic scintillators for detection of neutrons and gamma rays
Detection of special nuclear materials (SNMs) at borders and ports of entry is critical to ensuring peaceful use of fissile materials. Plastic scintillators are viable option for first line of detection for these materials ...
