The Ford Motor Company of Canada, 1903-1929: Canadian content in a multinational setting.

This study aims at clarifying the development of the Canadian Ford Company by examining its financial, industrial and marketing strategies under the direction of its Canadian managers, Gordon McGregor and Wallace R. Campbell. Ford of Canada resulted from the initiative of a local Windsor entrepreneur who established his company through a business agreement with an American industrial genius. Unlike Nash, Studebaker and the Hudson Motor Company, Ford became a Canadian manufacturing firm, managed by Canadians pursuing Canadian profit, production and employment goals. By following the development of the first major Canadian auto industry, this study will highlight the company\u27s progress and suggest that The Ford Motor Company of Canada followed policies adopted in its best interests. These policies responded to Canadian and Imperial conditions and occasionally contradicted parent company policies in Dearborn, Michigan. This thesis will investigate areas of contradiction and emphasize the Canadian nature of the operation. (Abstract shortened by UMI.)Dept. of History, Philosophy, and Political Science.

Grating Aligned Ferroelectric Liquid Crystal Devices

This thesis is concerned with the vertical grating alignment of ferroelectric liquid crystals (FLCs). FLCs exhibit fast electro-optic response times compared to traditional nematic devices, and so are of particular interest for use in micro-displays and liquid crystal on silicon (LCoS) spatial light modulators. Unfortunately such materials are highly susceptible to shock induced ow. This work introduces the VGA-FLC device geometry: a vertical grating aligned ferroelectric liquid crystal display. The vertical alignment gives preferential alignment to the smectic layers, and the amplitude and pitch of the grating ensure stable alignment of the c-director of the FLC. The combined effect is shown to result in a shock-stable FLC geometry. The device is addressed with in-plane electric fields, and is shown to obtain fast optical response times. The theory and physics of the device is explored, and further experiments are suggested that can be performed for device optimisation

Information Geometry and Asymptotics for Kronecker Covariances

We explore the information geometry and asymptotic behaviour of estimators for Kronecker-structured covariances, in both growing-$n$ and growing-$p$ scenarios, with a focus towards examining the quadratic form or partial trace estimator proposed by Linton and Tang. It is shown that the partial trace estimator is asymptotically inefficient An explanation for this inefficiency is that the partial trace estimator does not scale sub-blocks of the sample covariance matrix optimally. To correct for this, an asymptotically efficient, rescaled partial trace estimator is proposed. Motivated by this rescaling, we introduce an orthogonal parameterization for the set of Kronecker covariances. High-dimensional consistency results using the partial trace estimator are obtained that demonstrate a blessing of dimensionality. In settings where an array has at least order three, it is shown that as the array dimensions jointly increase, it is possible to consistently estimate the Kronecker covariance matrix, even when the sample size is one.Comment: 42 total pages, 21 pages of main text, 4 tables, 8 figure

The biomechanical function of periodontal ligament fibres in orthodontic tooth movement

Orthodontic tooth movement occurs as a result of resorption and formation of the alveolar bone due to an applied load, but the stimulus responsible for triggering orthodontic tooth movement remains the subject of debate. It has been suggested that the periodontal ligament (PDL) plays a key role. However, the mechanical function of the PDL in orthodontic tooth movement is not well understood as most mechanical models of the PDL to date have ignored the fibrous structure of the PDL. In this study we use finite element (FE) analysis to investigate the strains in the alveolar bone due to occlusal and orthodontic loads when PDL is modelled as a fibrous structure as compared to modelling PDL as a layer of solid material. The results show that the tension-only nature of the fibres essentially suspends the tooth in the tooth socket and their inclusion in FE models makes a significant difference to both the magnitude and distribution of strains produced in the surrounding bone. The results indicate that the PDL fibres have a very important role in load transfer between the teeth and alveolar bone and should be considered in FE studies investigating the biomechanics of orthodontic tooth movement. © 2014 McCormack et al
