Fall 2009
In the refining industry, the cost of a power system interruption is dominated by an associated loss of production. Power distribution within a refinery includes a set of production units within a highly inter-dependent process, where the outage of a single unit affects the production 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...

Evaluation of Frailty Assessment Tools and their Measurement Properties in Chronic Kidney Disease
DownloadSpring 2022
Background: Frailty is three to seven times more common in people with chronic kidney disease (CKD) than in those with normal kidney function. Although frailty and its impact in CKD is well-recognized, the measurement properties of the tools used to assess this syndrome are not known. The aim of...

The validity, reliability and time requirement of study model analysis using cone-beam computed tomography generated virtual study models
DownloadFall 2011
Objectives: To investigate the validity, reliability and time spent on performing a full orthodontic study model analysis (SMA) on Cone Beam Computed Tomography (CBCT)-generated dental models (Anatomodels) compared with conventional Plaster models and a subset of Extracted Premolars. Methods:...

Spring 2010
Fatigue assessments have been carried out predominantly with quasi-deterministic approaches, such as the use of S–N curves. However, both the loading and the resistance of fatigue prone components are subjected to significant uncertainties. Consequently, a prediction of the remaining fatigue life...

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),...

The Effects of Axial Loading on the Disc and Motion Segment Relative to Disc Degeneration and Pain Using Novel MRI Biomarkers
DownloadSpring 2017
The underlying pathology of low back pain (LBP) is poorly understood. Although MRI is often used as a sensitive modality for depicting pathoanatomical abnormalities, it is often clinically inconclusive due to a lack of specificity. While most patients experience symptoms when the spine is loaded,...

Fall 2014
Although pens and paper are pervasive in the analog world, their digital counterparts, styli and tablets, have yet to achieve the same adoption or frequency of use. Digital styli should provide a natural, intuitive method to take notes, annotate, and sketch, but have yet to reach their full...

Tooth length measurement accuracy and reliability with cone-beam CT and panoramic radiography
DownloadSpring 2010
This study assessed the accuracy and reliability of tooth length measurements through axial, coronal and sagittal serial slices of CBCT volumes; conventional panoramic radiographs; and CBCT panoramic reconstructions to that of a digital caliper gold standard. Samples consisted of maxillary...
