A MAC Protocol For Harsh Industrial IoT Applications
Heavy industries such as mining, constructions and transportation manufacturing are currently facing many dilemmas due to the critical and harsh conditions that they collide with during their operations. Such environments ... -
A machine learning application for form-finding of tensegrity structures
Tensegrity (tensional integrity) is a structural principle where rigid elements (struts) under compression are held together by a network of elastic elements (cables) under tension. Tensegrity structures have many applications ... -
Machine Vision Based Inspection: Case Studies on 2D Illumination Techniques and 3D Depth Sensors
(2012-03-01)This paper investigates two distinct, but related, topics in machine vision. The first is the effect of lighting on the performance of a 2D vision-based inspection system. The lighting component of machine vision has often ... -
Machineries of War and Mechanisms of Change in World Politics
(2007-10-01)The purpose of this dissertation is to anticipate changes in the international system by examining changes in Western defence industries. The defence industries are a mechanism for producing power. In an anarchic ... -
MACHINERY-RELATED OPERATIONAL FACTORS AS DETERMINANTS OF INJURY ON CANADIAN PRAIRIE FARMS
(2009-09-03)Background: Agriculture remains one of the most hazardous occupations in Canada. Approximately one-half of all agricultural injuries are due to machinery. The etiology of machinery-related injury remains poorly ... -
A macroeconomic study of the costs, consequences and policy implications of sectorial labour reallocation
(2008-08-14)This thesis uses a macroeconomic approach to study labour adjustments following sector-specific shocks. I develop a general model, investigate its dynamic adjustment process and apply it to study the Canadian economy in ... -
Macromolecular Orientation of Rigid Dumbbells in Shear Flow
We use molecular modeling to study the non-equilibrium behaviour of polymeric fluids. Specifically, we explore the macromolecular orientation induced by shear flow fields. We choose the simplest molecular model, the rigid ... -
MagicWand: A Comparison of Gestural Affordances Between Cylindrical and Flat Display Form Factors
An affordance is the intrinsic ability of an object to allow an action. Affordances are generated by matching the fit of the body under action to the physical shape of the object. For example, a vertical door handle affords ... -
Magnetic Barkhausen Noise Measurements Using Tetrapole Probe Designs
(2014-12-23)A magnetic Barkhausen noise (MBN) testing system was developed for Defence Research and Development Canada (DRDC) to perform MBN measurements on the Royal Canadian Navy’s Victoria class submarine hulls that can be correlated ... -
Magnetic Barkhausen Noise Testing: Steel Grades and Stress Response
(2015-10-03)Magnetic Barkhausen Noise emissions are discontinuous magnetization changes within ferromagnetic materials that have been subjected to changing applied magnetic fields. These emissions are sensitive to microstrutural ... -
Magnetic fields and the variable wind of the early-type supergiant β Ori
(2012-04-30)Supergiant stars of spectral types B and A are characterized by variable and structured winds, as revealed by variability of optical and ultraviolet spectral lines. Non- radial pulsations and magnetically supported loops ... -
The Magnetic Fields of Ap Stars From High Resolution Stokes IQUV Spectropolarimetry
(2014-05-28)In this thesis we describe the acquisition of high resolution time resolved spectropolarimetric observations of 7 (bright and well understood) Ap stars in Stokes IQUV using the ESPaDOnS and Narval spectropolarimeters at ... -
A Magnetic Flux Leakage NDE System for CANDU Feeder Pipes
(2010-03-11)This work examines the application of different magnetic flux leakage (MFL) inspection concepts to the non destructive evaluation (NDE) of residual (elastic) stresses in CANDU reactor feeder pipes. The stress sensitivity ... -
Magnetic, chemical and rotational properties of the Herbig Ae/Be binary system HD 72106
(2007-09-17)Recently, magnetic fields have been detected in a handful of pre-main sequence Herbig Ae and Be (HAeBe) stars. This hints at an evolutionary connection between magnetic HAeBe stars and Ap and Bp stars. Ap/Bp stars are ... -
Magnitude and controls of microbial nitrate production in the streams and till of a glaciated alpine catchment, Canadian Rocky Mountains, Alberta
(2012-04-26)In the summer of 2010, fieldwork was conducted in the Robertson Valley, Canadian Rocky Mountains, Alberta to assess the magnitude and controls of microbial nitrification in proglacial till and in supraglacial, subglacial, ... -
Making 'Mr. Hockey': Race, Gender, Class, and Nation in Media Representations of Gordie Howe
In this dissertation I study media representations of Gordie Howe, also known as ‘Mr. Hockey,’ who has been an idealized image of a hockey player and a ‘true’ Canadian during the Canadian postwar era. By taking Howe as ... -
Making Hair Matter: Untangling Black Hair/Style Politics
(2010-06-23)Hair is a remarkably complex material-semiotic entity. Caught on the cusp between self/society, meticulously contrived and purposely styled, hair is crucial in the articulation of identity and difference. However, although ... -
MAKING HOME: PERFORMANCE, SOCIABILITY, AND IDENTITY IN ST. JOHN’S, NEWFOUNDLAND, 1810-1860.
St. John’s, Newfoundland underwent an economic and cultural transformation in the early nineteenth century. With a growing year-round resident population, and mercantile operations increasingly headquartered out the town, ... -
Making Settler Space: George Dawson, the Geological Survey of Canada and the Colonization of the Canadian West in the Late 19th Century
(2009-09-08)This dissertation examines George Dawson’s efforts to traverse several of the significant blank spaces that pervaded the map of Western Canada in the two decades following Confederation in 1870-71 on behalf of the Geological ... -
Making Sure Hungry Plants Get Fed: The Dual-Targeted Purple Acid Phosphatase Isozyme AtPAP26 is Essential for Efficient Acclimation of Arabidopsis Thaliana to Nutritional Phosphate Deprivation
(2009-11-18)Acid phosphatases (APases; E.C. 3.1.3.2) catalyze the hydrolysis of phosphate (Pi) from Pi monoesters and anhydrides within the acidic pH range. Induction of intracellular and secreted purple acid phosphatases (PAPs) is a ...
