Fall 2017
Approaches for accurate prediction of ductile failure of polyethylene (PE) pipe have been explored using the experimentally determined, material-specific damage parameter D. Although many methods are available for quantifying the D values, they are mainly suitable for metallic materials. For...

Data-driven approaches to defining material property and performance relationships of armor ceramics undergoing dynamic loading
DownloadSpring 2023
This thesis utilizes a combined numerical and machine learning approach to explorethe performance of an alumina ceramic tile undergoing high-velocity impact. The fi-nite element model is established by incorporating a user-defined Johnson-Holmquist-Beissel (JHB) material model within the...

Data-Driven Fault Detection, Isolation and Identification of Rotating Machinery: with Applications to Pumps and Gearboxes
DownloadFall 2012
Fault diagnosis plays an important role in the reliable operation of rotating machinery. Data-driven approaches for fault diagnosis rely purely on historical data. Depending on how a diagnosis decision is made, this thesis divides data-driven fault diagnosis approaches into two groups:...

Decision Models for Operation and Maintenance of Offshore Wind Farms Considering Uncertainties
DownloadFall 2020
Wind energy is an important renewable resource to meet the continually increasing global energy demand. The high wind power potential in the sea has led to the development of wind farms in the sea, referred to as offshore wind farms (OWFs). OWFs are an array of wind turbines built in the sea to...

Spring 2014
The objective of this study is to develop a decision-making framework for maintenance management targeting remotely operated assets. Using external data as an input, the developed framework can improve decision-making ability on maintenance from the field or remote office. This was achieved by...

Fall 2023
This study examines high-penetration of renewable energy options for Fort Chipewyan (an off-grid community in northern Alberta, Canada). This analysis goes beyond modelling hybrid diesel-renewable electricity supply, to also consider deep electrification scenarios that not only aim to electrify...

Fall 2023
Unmanned aerial vehicles or UAVs have largely become and continue to be an inseparable part of modern warfare, security and surveillance systems, first aid response, aerial cinematography and many other sectors. Therefore, achieving full autonomy for UAVs and drones would ensure mass mobilization...

Deformation and fracture behaviour of extruded CPVC sheet and pipe after exposure to chemical solvents
DownloadSpring 2021
The work described in this thesis concerns the influence of chemical solvents (acetone and primer) on the strength and ductility of extruded chlorinated polyvinyl chloride (CPVC) sheet with a nominal thickness of 1/32-inch, and of pipe that is 2-inch in diameter. The work also includes finite...
