Fall 2023
This thesis explores vibration monitoring of infrastructure or machinery through an uncrewed aerial vehicle (UAV) also commonly referred to as a drone. The vibration signature of an object may be used to assess the health of that object. This thesis looks at the means of acquiring this vibration...

Neonatal infants in need of advanced care, often require transportation via road ambulance to neonatal intensive care units. The ambulance exposes these vulnerable infants to potentially harmful noise and vibration. To better understand the levels of vibration, this paper maps the magnitude of...

Fall 2018
Vibration signal analysis has been widely used for planetary gearbox condition monitoring and fault diagnosis. Vibration signals are normally measured by sensors mounted on a planetary gearbox’s housing. A vibration signal contains rich information about the health condition of the machinery....

Fall 2020
Gearboxes are widely used in modern power transmission systems such as wind turbines, helicopters, and railway vehicles. Due to inappropriate operation conditions or fatigue degradation, faults may develop in gears. If early faults cannot be detected and their severity assessed in a timely...

Most of Canada’s municipal infrastructure, including bridges, was built between the 1950s and 1970s. With design lives of 50-100 years, many of these structures are due for major rehabilitations or replacements. With the growing costs of deteriorating infrastructure, the cost savings from...

Vibrational absorption, vibrational circular dichroism and theoretical studies of methyl lactate molecules in solution phase and in argon matrices
DownloadSpring 2011
The infrared vibrational absorption (VA) and vibrational circular dichroism (VCD) spectra of methyl lactate in carbon tetrachloride and methanol have been measured in the 1000-1800 cm-1 region. Noticeable changes due to the solute self-aggregation and solvent-solute intermolecular...
