Fall 2020
Adolescent idiopathic scoliosis (AIS) is a spinal disorder causing abnormal curvature of the spine in three dimensions (3D), starting in the patient’s adolescence, and having no known cause. Bracing is the most common non-surgical method of treating AIS, but the brace design is heavily reliant on...

Application of a biomechanical finite element spine model to the vicious cycle scoliosis growth theory: evaluation of improved FEA geometry and material assignment
DownloadFall 2009
Scoliosis is defined as the abnormal three dimensional curvature of the spine with 80% of all cases being idiopathic in nature. If left unchecked, this condition can cause cardio-pulmonary complications and occasionally death. Currently, the most common method of treatment of scoliosis is through...

Application of ultrasound to measure coronal curvature and vertebral rotation in adolescent idiopathic scoliosis
DownloadFall 2014
Adolescent idiopathic scoliosis (AIS) is a three-dimensional (3D) spinal deformity occurring during adolescence with no known causes. Both the coronal curvature and vertebral axial rotation (VAR) are important parameters to assess the severity, predict the progression and evaluate the outcomes of...

Design, Simulation and Evaluation of Effective Industrial Information Systems: Case of Machine Condition Monitoring and Maintenance Management Information Systems
DownloadFall 2013
Industrial information systems can improve the management of industrial operations by providing relevant and timely information on the status of physical assets via condition and process monitoring systems, and by enabling the effective use of data by systems and processes that restore proper...

Determining Reliability and Validity of the Modified Gingival Index when Reviewed in an Image-based Survey Format
DownloadFall 2019
Gingivitis affects 50-90% of the Canadian adult population, with the accumulation of dental plaque being the most common cause. Clinically, gingivitis is characterized by red, swollen gums, bleeding upon stimulation, and a loss of stippled, knife-edged margins. Gingivitis will not necessarily...

Gallium nitride (GaN) high-electron mobility transistors (HEMTs) have great potential for high-power and high-frequency applications, but current leakage issues compromise their reliability. This research focuses on developing GaN metal-oxide semiconductor field-effect transistors (MOSFETs),...

Development of a Detection Model for Curve Progression in Adolescents with Idiopathic Scoliosis
DownloadSpring 2022
Adolescent idiopathic scoliosis (AIS) is a three-dimensional (3D) structural spinal disorder recognized by lateral curvatures. The routine for monitoring of AIS is taking an X-ray every six months to check the curve severity and curve progression. Taking repetitive radiographs is not desirable...

EMG Measurement of the fatigability of paraspinal muscles of patients with adolescent idiopathic scoliosis
DownloadFall 2014
This thesis aimed to address two separate questions, 1) Are current exercise approaches to scoliosis based on a strong foundation in the literature? And 2) Do the paraspinal muscles of patients with adolescent idiopathic scoliosis (AIS) differ in endurance properties from controls? The first...

The increasing level of system complexity in the current competitive market implies that efficient asset management is of paramount importance, particularly for systems with costly downtime and failure. Timely detection of faults and failures through an efficient reliability and health management...

Evaluating the Performance of the Uncorrected and Corrected Reliability Alpha for Range Restriction and the Confidence Intervals in a Single and Meta-Analytic Study
DownloadSpring 2013
Range restriction has long been a methodological problem in educational and psychological research (Hunter & Schmidt, 2004), and this usually leads to a downward-biased estimate of a statistic. Even though much research has examined the performance of Pearson’s correlation under range restriction...
