Theses and Dissertations
This collection contains theses and dissertations of graduate students of the University of Alberta. The collection contains a very large number of theses electronically available that were granted from 1947 to 2009, 90% of theses granted from 2009-2014, and 100% of theses granted from April 2014 to the present (as long as the theses are not under temporary embargo by agreement with the Faculty of Graduate and Postdoctoral Studies). IMPORTANT NOTE: To conduct a comprehensive search of all UofA theses granted and in University of Alberta Libraries collections, search the library catalogue at www.library.ualberta.ca - you may search by Author, Title, Keyword, or search by Department.
To retrieve all theses and dissertations associated with a specific department from the library catalogue, choose 'Advanced' and keyword search "university of alberta dept of english" OR "university of alberta department of english" (for example). Past graduates who wish to have their thesis or dissertation added to this collection can contact us at erahelp@ualberta.ca.

Traditionally in pipeline steels and welds, ultrasonic testing (UT) has been used for crack and/or flaw detection. The work presented in this Thesis explores the use of this technique to characterize the microstructure of pipe steels. Ultrasonic velocity calculations, for shear and longitudinal...

This thesis is concerned with the ultrasonic heart image segmentation problem using parametric active contour model. Most of the existing parametric models consider only either the edge or the regional information. In this thesis, we propose a new parametric active contour model considering both...

Osteoporosis is a bone disease characterized by the degradation of mechanical competence and support of the skeleton, leading to fracture risk of the wrist, vertebrae, and hip. The disease is due to major decrease of mass and deterioration of micro-structure of bone tissues. In this study, bone...

In this thesis, ultrasonic B-scan signal processing is investigated. A B-scan displays a cross-sectional view of the test piece and defects within it. Compared to A-scan signals, B-scan images offer more reliable fault detection. Nonetheless, traditional ultrasonic signal processing methods are...

ML80 and Grade 483 are heat treatable steels, produced by a quench and temper process, that are used in the oil and gas industry. The development of the microstructure during heat treatment is important to ensure that the correct properties are achieved for these steels. However, a real-time...

Molecular imaging techniques are important for understanding fundamental biological processes and genetic functions in organisms. Non-invasive, high-resolution, deep imaging, as well as the ability to separate molecular species, are all critical to the success of a molecular imaging technique....

Percutaneous procedures, those involving the insertion of needles into tissue, encompass a wide array of clinical applications and are used in both therapeutic and diagnostic modalities. In either of these modalities, the needle must be steered accurately towards a target location to maximize the...
