A Comparison Study of the Reliability Coefficients from Five Approaches to Reliability Estimation
DownloadFall 2015
In order to estimate reliability by a single administration of one test form, various approaches and corresponding reliability coefficients have been proposed so far. Currently, the five most influential approaches are: internal consistency, lower bound, principal components analysis (PCA),...

Accuracy and reliability of CBCT imaging for adenoid hypertrophy screening among a sample of oral maxillofacial radiologists and orthodontists and by an automated commercial imaging software
DownloadSpring 2016
Objectives. This thesis project aimed to investigate the diagnostic performance of different dental specialists and a modern dental imaging software to evaluate adenoidal hypertrophy compared with the current reference standard diagnosis by an Otorhinolaryngologist – Head and Neck Surgeon (OHNS)...

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 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...
