Numerical study of rockburst damage around excavations induced by fault-slip, A
The increasing depths of mining and associated in-situ stresses have made rockburst a serious risk for underground mining and tunneling. Therefore, it is important to understand the energy mechanisms of unstable rock failure ... -
Investigation of backwards erosion piping by data driven modeling
This thesis investigates backwards erosion piping (BEP) as a failure mechanism; it focuses on the ability to use pore water pressure (PWP) measurements to (1) monitor, (2) investigate progression of, and (3) better predict ... -
SELF-REFLECTIVE EXPERIENTIAL LEARNING FOR PERSISTENT AUTONOMY
Robots have been expected to achieve persistent autonomy for a long time, in which robots are required to safely operate in unknown environments for extended lengths of time while without human interventions. Reinforcement ... -
Quantifying the effect of conductive polymer binders on Li-O2 battery performance
Electric vehicles (EVs) have gained popularity in recent years for their ability to reduce carbon emissions. However, increased commercial adoption requires advancements in battery energy density, to enable longer drive ... -
Laser brazing of reaction-bonded silicon carbide with a silicon-aluminum-titanium filler alloy
This work focuses on the feasibility of joining reaction-bonded silicon carbide (RB-SiC) with a laser heat source. A ternary Si-Al-Ti alloy was used as filler metal. Research consisted of four phases: laser metrology, ... -
Nine-component seismic amplitude inversion : a case study in the Eagle Ford shale
Over the last decade, unconventional hydrocarbon resources have led the United States to a spot atop the list of largest oil producers in the world. During this time, major improvements in both technology and the general ... -
Application of geostatistical methods for the quantification of multiple-scale uncertainty due to aleatory geologic variability, The
Tunneling projects in rock are characterized by a high degree of spatial uncertainty, which is due in part to the natural, random (aleatory) variability the rock possesses. Some degree of variability is intrinsic to all ... -
Quantifying the effects of residential infill redevelopment on urban stormwater quality
The population of Denver, Colorado is expected to nearly double by 2050, raising concerns of local and regional decision makers regarding water supply and water quality. Urban redevelopment trends in the Denver metro area ... -
Toughness and separation improvement of thick plate X70 pipeline steels
The effects of microstructure, texture, and material constraint for four American Petroleum Institute (API) X70 grade steel plates of varying thickness (13.5, 15.5, 22, and 32 mm) on separations and the subsequent effects ... -
Geochemical controls on the fluid evolution of submarine and subaerial ore-forming hydrothermal systems
Seafloor hydrothermal venting influences the chemistry of the oceans and crust, is linked to the development of chemosynthetic life, and is associated to the formation of volcanic-hosted massive sulfide (VHMS) deposits. ... -
Laser welding behavior of laser powder bed fusion additive manufactured 304L stainless steel
Additive manufacturing (AM) is becoming of great interest due to the ability to create one of a kind, complex components in a relatively rapid manner. However, applications of AM components are limited because little is ... -
Computational modeling of extravascular platelet aggregation under flow
Platelets in blood aggregate as part of the normal physiologic response to a blood vessel injury. Extravascular injuries, those that occur outside the blood vessel, are not well understood and lack numerical tools to study ... -
Scalable synthesis of lithium sulfide nanocrystals for next generation battery technologies
Batteries play extremely important roles in electricity storage systems. Managing the temporal nature of ever increasing renewable power generation requires next generation batteries with larger power and energy density, ... -
Landslide susceptibility mapping using a logistic regression approach : a case study in Colorado Springs, El Paso County, Colorado
A landslide is defined as a mass-wasting process of soil, rock or debris that moves downslope (U.S. Geological Survey, 2004). Landslides can occur on any terrain if the geomorphic, geological, and hydrological conditions ... -
On the kinetic arrest of hydrate slurries
Natural gas hydrates are clathrate compounds consisting of a network of hydrogen-bonded water molecules that host small hydrocarbons within the resulting structure. Subsea oil & gas production pipelines can provide the ... -
Impact of synthetic and natural surface-active components on hydrate agglomeration, The
Gas hydrates present a major flow assurance challenge due to the relatively fast timescales at which they can form, agglomerate, and plug a flowline. Thermodynamic inhibitors (THIs) are a common strategy for preventing ... -
Sediment movement and basin evolution and fill in a shale-cored deepwater fold and thrust belt, NW Borneo Malaysia
This thesis investigates the deformation and sedimentation in deepwater fold and thrust belts (DWFTB) to better understanding of the manner in which structure and sedimentation interact. First, this thesis reviews the ... -
Ultrasonic velocity tomography method for damage evaluation in rocks
The naturally occurring fractures and discontinuities have a significant influence on the mechanical and hydraulic properties of rocks and various engineering problems such as reservoir development, hydraulic fracturing, ... -
Statistical methods for predicting individual movement patterns
One of the most potentially useful methods for truly understanding our habits is by observing the data captured by our cellular phones. In 2009, Nokia launched the Lausanne Data Collection Campaign, which was designed to ... -
Microstructural evolution and mechanical properties of heavily cold-rolled and subsequently annealed copper titanium alloys
Cold-rolled Cu-Ti alloy sheets are commonly used as connectors for electronic devices, because of their excellent mechanical properties and formability relative to conventional commercial copper alloys. Cu-Ti alloy sheets ...
