Experimental Study of Low-Speed Gearbox Faults Using Vibration and Acoustic Emission Signals
With the goal of finding an effective condition monitoring tool for low-speed gearbox applications, vibration-based tests and Acoustic Emission (AE) tests have been performed on several gearbox sets in normal and faulty ... -
A Flexible Machine Vision System for Small Parts Inspection Based on a Hybrid SVM/ANN Approach
The automated inspection and sorting of parts is a common application of Machine Vision (MV). The sorting of parts is possible only after reliable classification. The goal of this thesis was to develop and validate a ... -
Radiation Damage Effect on Mechanical Properties and Microstructure of X-750 Ni-based Superalloy
Inconel X-750 is an age-hardened Ni-based superalloy with high mechanical strength and creep resistance. The X-750 alloy is extensively used in the cores of reactors, such as spacers in CANada Deuterium Uranium (CANDU) ... -
Industrial-Scale Autonomous Vehicle Path Following by Feedback Linearized Iterative Learning Control
This work describes and demonstrates, through simulation and field trials, a technique for autonomous wheeled vehicle path following that uses iterative learning control (ILC) performed in a feedback linearized space to ... -
Factors Affecting Traction Coefficients During Intermittent Sliding Motion in Textured Metal-Polyethylene Bearings
In cases of severe arthritis, a metal-on-ultra-high molecular weight polyethylene (UHMWPE) total joint arthroplasty (TJA) is the primary solution. Wear of UHMWPE is a concern as it causes poor bearing performance and a ... -
Effect of Foot Shells on Mechanical Properties of Prosthetic Foot Systems
Prosthetic foot systems are typically composed of both structural keel and foot shell components. The interaction between these components is considered by the prosthetic device industry with respect to designing higher ... -
A Step in the Right Direction: Evaluating the Effectiveness of Customized Stepping Game Software and Nintendo Wii Balance Boards for Balance Rehabilitation Therapy and Measurement
Falling is a serious issue among adults over the age of 65 as the incidence and impact of falls rapidly increases with age. Traditionally, exercise interventions have proven to be effective in improving balance and strength, ... -
