    Authors: Alexander, Nicolle;

    More than two decades after its introduction, neoliberal ideology has increasingly created a class and race-based gap in relation to student achievement in Ontario’s education system. Due to market-based rhetoric shaping policies and legislation, schools are increasingly encouraging students to adhere to the demands of a newly globalized world with a focus on the economy, regardless of their background. This study aims to analyze the presence of neoliberal reforms in Ontario’s education system through decisions made in government from Mike Harris’ in 1995 to the present Doug Ford administration. Specifically, I investigate how the so-called knowledge economy has produced a system that enables students deemed marketable, often from middle- and upper-class white backgrounds, and disables non-marketable students, most often the working poor and the working class, and racial and ethnic minorities, through funding cuts, heightened accountability, and standardized testing. By evaluating Ministry of Education policy documents and documents for both Conservative Premier campaigns, I analyzed the rhetoric used to introduce, consolidate and solidify neoliberal discourse throughout the past twenty years. The results showed that by simplifying education to quantifiable measures, the education system now measures concepts such as equity and inclusion in schools through standardized testing and monthly reports. Further, the rhetoric used to solidify equity and inclusion within the system focuses more on the presentation of both rather than materializing its action in schools. In order to minimize the current student achievement gap in our education system, funding needs to be focalized in social services cut by our government level to properly re“instate” the intended actions of these policies.

    Authors: Lin, Yijun;

    In light of the existence of an informal sector in most developing countries, economists are beginning to reconsider the integrated tax reform consisting of a reduction in tari®s with an increase in VAT that has been advocated by the IMF in recent years. This paper explores the welfare change of such a reform in an economy in which the size of the informal sector is endogenously determined. Assuming that products are nontraded, the levy of VAT distorts the aggregate output; allowing the size of the informal sector to be determined endogenously worsens the situation. This leads to a conclusion which tends to favor an integrated tax reform toward tari®s under some plausible conditions. This result may help to explain the slow adoption of VAT in many developing countries.

    Authors: Cong, Binghao;

    The primary objective of this thesis is to improve optical setups of a constant volume combustion chamber to better understand the vaporization and spray characteristics of various fuels. The schlieren imaging technique is utilized to visualize phenomena that are challenging to observe directly. In this thesis, the schlieren imaging is used to observe the spray and ignition characteristics of DME and diesel fuels under high injection pressure. First, various optical techniques are discussed and compared under the same test condition including schlieren, shadowgraph, and direct imaging. The advantages for these techniques are presented and the most appropriate technique for different testing scenarios is proposed. Second, the spray and ignition characteristics of DME and diesel are compared. The inert spray for both fuels are observed and compared using schlieren imaging technique. The reactive spray for both fuels are observed and compared using direct imaging and shadowgraph imaging system.

    Authors: Edrisy, Mohamed;

    The emergence of commercial FEA solvers was a significant breakthrough that boosted the accuracy and complexity of engineering design. While composite materials are special materials, their mechanical properties can be custom made by considering the needs and requirements of the design problem. Given the rapidly expanding global consumption of composite materials, access to FEA solvers capable of assigning these materials is an absolute requirement.The CATIA software is a platform for designing, analyzing, and manufacturing of parts. However, there is no meaningful documentation in the public domain exploring the finite element functionalities of CATIA software for composite materials. Isotropic materials are used in numerous references investigating the CATIA FEA solver; however, the extension to composite materials has been lacking. The present study investigates two phenomena: (1) the procedure to import composite material properties into the Generative Structural Analysis workbench, and (2) the pre-processing and the post-processing toolbars and functionalities pertaining to this matter. The thesis does not address the CAD modelling aspects of the composites per se since there are many references available concentrating on such issues in the CATIA public literature.The composite models are selected from different scenarios labeled as benchmark problems. The results generated by CATIA’s native FEA solver for the static, dynamic, and buckling cases are compared with other tools available to the engineering community. These tools encompass the Classical Lamination Theory and two commercial CAE codes, known as ABAQUS and ANSYS.

    Authors: Ma, Yan;

    A low-cost thermal pressure sensor based on short-distance thermal conduction and used in atmospheric pressure range has been explored. This simple device consists of a heater made of a polysilicon resistor, a heat sink made by the silicon substrate and a tiny air gap between them. With innovative ideas and simple processes, the gap can be made in the order of nanometers inexpensively, which significantly increases the measurement range of the sensor. Devices capable of measuring 700kPa (7atm) or more have been fabricated with a 3-mask, 3pm and CMOS compatible process. The device can be made as small as 50x50pm2, less than the size of a standard bonding pad. The simple process and low cost associated with these devices could make commercial adaptation promising.

    This project compares four different hedging techniques using spot and futures exchange rates of the British Pound. Specifically, the OLS regression model, the vector autoregressive model (VAR), the vector error correction model (VECM) and the Multivariate GARCH with error correction model are applied. Hedging effectiveness is measured in terms of minimizing variance of hedged portfolios. The VAR model and the VECM offer the same performance, which is higher than that of the OLS model. Although the multivariate GARCH with error correction model is the only one being able to capture the time varying nature of the hedge ratio, the hedging performances of four str ategies do not differ very much, either in-sample or out-of-sample. Therefore, although complex models are able to capture more figures of the data set, there is no evidence that they will give significant better hedging performance.

    Authors: Eyrich, Charles Beaufort;

    The exchange stiffness, Aex, is one of the key parameters controlling magnetization reversal in magnetic materials but is very difficult to measure, especially in thin films. We developed a new technique for measuring the exchange stiffness of a magnetic material based on the formation of a spin spiral within two antiferromagnetically coupled ferromagnetic films [1]. Using this method, I was able to measure the exchange stiffness of thin film Co alloyed with Cr, Fe, Ni, Pd, Pt and Ru. The results of this work showed that the rate at which a substituent element reduces the exchange stiffness is not directly related to its effect on the magnetization of the alloy. These measured trends have been understood by combining measurements of element specific magnetic moments obtained using X-ray magnetic circular dichroism (XMCD) and material specific modeling based on density functional theory (DFT) within the local density approximation (LDA). The experimental results also hint at significant reduction of the exchange stiffness at the interface that can account for the difference between our results and those obtained on bulk materials.

    Authors: Stone, Rachel Marie;

    Monitoring intracranial pressure (ICP) has become an important practice in patients with elevated ICP (e.g., traumatic brain injury) to improve patient outcome. However, little information exists surrounding chronic, but sub-clinical elevations in ICP, which may stem from classic cardiovascular risk factors, such as elevated blood pressure (BP). The current methods to assess ICP are invasive and costly; but optic nerve sheath diameter (ONSD) and blood flow pulsatility (pulsatility index; PI) are promising non-invasive techniques, both of which have been reported to strongly correlate with invasive measures of ICP in pathology. However, the interactions of BP, ONSD and PI in otherwise healthy adults, remains undetermined. Accordingly, the purpose of this investigation was to determine the relationship between ONSD, PI and BP, and to highlight possible sex differences in a population of young healthy adults. Sixteen participants (6 females) underwent assessment of arterial BP, ONSD (left and right eyes) and PI (left common carotid artery) using ultrasound. There was a strong correlation between mean ONSD (left and right eye combined) and PI (R=0.735, p=0.001). There was no significant relationship between PI and BP (R=0.058, p=0.832) or ONSD and BP (R=0.272, p=0.309). Additionally, there was a significant difference between males and females for mean ONSD, whereby males demonstrated a larger diameter (males=0.4860.110 vs. females=0.3530.062cm; p=0.018), but there was no significant difference in PI between males and females (males=2.3630.613 vs. females=1.9500.196; p=0.136). Results of this study confirm the relationship between ONSD and PI in a healthy population. While ICP was not directly assessed in the current study, the strong associations between ONSD and PI suggest that their combined assessment may be employed as a tenable surrogate to non-invasively measure ICP when the invasive measure of ICP is unfeasible.

    Authors: Alexander, Nicolle;

    More than two decades after its introduction, neoliberal ideology has increasingly created a class and race-based gap in relation to student achievement in Ontario’s education system. Due to market-based rhetoric shaping policies and legislation, schools are increasingly encouraging students to adhere to the demands of a newly globalized world with a focus on the economy, regardless of their background. This study aims to analyze the presence of neoliberal reforms in Ontario’s education system through decisions made in government from Mike Harris’ in 1995 to the present Doug Ford administration. Specifically, I investigate how the so-called knowledge economy has produced a system that enables students deemed marketable, often from middle- and upper-class white backgrounds, and disables non-marketable students, most often the working poor and the working class, and racial and ethnic minorities, through funding cuts, heightened accountability, and standardized testing. By evaluating Ministry of Education policy documents and documents for both Conservative Premier campaigns, I analyzed the rhetoric used to introduce, consolidate and solidify neoliberal discourse throughout the past twenty years. The results showed that by simplifying education to quantifiable measures, the education system now measures concepts such as equity and inclusion in schools through standardized testing and monthly reports. Further, the rhetoric used to solidify equity and inclusion within the system focuses more on the presentation of both rather than materializing its action in schools. In order to minimize the current student achievement gap in our education system, funding needs to be focalized in social services cut by our government level to properly re“instate” the intended actions of these policies.

    Authors: Lin, Yijun;

    In light of the existence of an informal sector in most developing countries, economists are beginning to reconsider the integrated tax reform consisting of a reduction in tari®s with an increase in VAT that has been advocated by the IMF in recent years. This paper explores the welfare change of such a reform in an economy in which the size of the informal sector is endogenously determined. Assuming that products are nontraded, the levy of VAT distorts the aggregate output; allowing the size of the informal sector to be determined endogenously worsens the situation. This leads to a conclusion which tends to favor an integrated tax reform toward tari®s under some plausible conditions. This result may help to explain the slow adoption of VAT in many developing countries.

    Authors: Cong, Binghao;

    The primary objective of this thesis is to improve optical setups of a constant volume combustion chamber to better understand the vaporization and spray characteristics of various fuels. The schlieren imaging technique is utilized to visualize phenomena that are challenging to observe directly. In this thesis, the schlieren imaging is used to observe the spray and ignition characteristics of DME and diesel fuels under high injection pressure. First, various optical techniques are discussed and compared under the same test condition including schlieren, shadowgraph, and direct imaging. The advantages for these techniques are presented and the most appropriate technique for different testing scenarios is proposed. Second, the spray and ignition characteristics of DME and diesel are compared. The inert spray for both fuels are observed and compared using schlieren imaging technique. The reactive spray for both fuels are observed and compared using direct imaging and shadowgraph imaging system.

    Authors: Edrisy, Mohamed;

    The emergence of commercial FEA solvers was a significant breakthrough that boosted the accuracy and complexity of engineering design. While composite materials are special materials, their mechanical properties can be custom made by considering the needs and requirements of the design problem. Given the rapidly expanding global consumption of composite materials, access to FEA solvers capable of assigning these materials is an absolute requirement.The CATIA software is a platform for designing, analyzing, and manufacturing of parts. However, there is no meaningful documentation in the public domain exploring the finite element functionalities of CATIA software for composite materials. Isotropic materials are used in numerous references investigating the CATIA FEA solver; however, the extension to composite materials has been lacking. The present study investigates two phenomena: (1) the procedure to import composite material properties into the Generative Structural Analysis workbench, and (2) the pre-processing and the post-processing toolbars and functionalities pertaining to this matter. The thesis does not address the CAD modelling aspects of the composites per se since there are many references available concentrating on such issues in the CATIA public literature.The composite models are selected from different scenarios labeled as benchmark problems. The results generated by CATIA’s native FEA solver for the static, dynamic, and buckling cases are compared with other tools available to the engineering community. These tools encompass the Classical Lamination Theory and two commercial CAE codes, known as ABAQUS and ANSYS.

    Authors: Ma, Yan;

    A low-cost thermal pressure sensor based on short-distance thermal conduction and used in atmospheric pressure range has been explored. This simple device consists of a heater made of a polysilicon resistor, a heat sink made by the silicon substrate and a tiny air gap between them. With innovative ideas and simple processes, the gap can be made in the order of nanometers inexpensively, which significantly increases the measurement range of the sensor. Devices capable of measuring 700kPa (7atm) or more have been fabricated with a 3-mask, 3pm and CMOS compatible process. The device can be made as small as 50x50pm2, less than the size of a standard bonding pad. The simple process and low cost associated with these devices could make commercial adaptation promising.

    This project compares four different hedging techniques using spot and futures exchange rates of the British Pound. Specifically, the OLS regression model, the vector autoregressive model (VAR), the vector error correction model (VECM) and the Multivariate GARCH with error correction model are applied. Hedging effectiveness is measured in terms of minimizing variance of hedged portfolios. The VAR model and the VECM offer the same performance, which is higher than that of the OLS model. Although the multivariate GARCH with error correction model is the only one being able to capture the time varying nature of the hedge ratio, the hedging performances of four str ategies do not differ very much, either in-sample or out-of-sample. Therefore, although complex models are able to capture more figures of the data set, there is no evidence that they will give significant better hedging performance.

    Authors: Eyrich, Charles Beaufort;

    The exchange stiffness, Aex, is one of the key parameters controlling magnetization reversal in magnetic materials but is very difficult to measure, especially in thin films. We developed a new technique for measuring the exchange stiffness of a magnetic material based on the formation of a spin spiral within two antiferromagnetically coupled ferromagnetic films [1]. Using this method, I was able to measure the exchange stiffness of thin film Co alloyed with Cr, Fe, Ni, Pd, Pt and Ru. The results of this work showed that the rate at which a substituent element reduces the exchange stiffness is not directly related to its effect on the magnetization of the alloy. These measured trends have been understood by combining measurements of element specific magnetic moments obtained using X-ray magnetic circular dichroism (XMCD) and material specific modeling based on density functional theory (DFT) within the local density approximation (LDA). The experimental results also hint at significant reduction of the exchange stiffness at the interface that can account for the difference between our results and those obtained on bulk materials.

    Authors: Stone, Rachel Marie;

    Monitoring intracranial pressure (ICP) has become an important practice in patients with elevated ICP (e.g., traumatic brain injury) to improve patient outcome. However, little information exists surrounding chronic, but sub-clinical elevations in ICP, which may stem from classic cardiovascular risk factors, such as elevated blood pressure (BP). The current methods to assess ICP are invasive and costly; but optic nerve sheath diameter (ONSD) and blood flow pulsatility (pulsatility index; PI) are promising non-invasive techniques, both of which have been reported to strongly correlate with invasive measures of ICP in pathology. However, the interactions of BP, ONSD and PI in otherwise healthy adults, remains undetermined. Accordingly, the purpose of this investigation was to determine the relationship between ONSD, PI and BP, and to highlight possible sex differences in a population of young healthy adults. Sixteen participants (6 females) underwent assessment of arterial BP, ONSD (left and right eyes) and PI (left common carotid artery) using ultrasound. There was a strong correlation between mean ONSD (left and right eye combined) and PI (R=0.735, p=0.001). There was no significant relationship between PI and BP (R=0.058, p=0.832) or ONSD and BP (R=0.272, p=0.309). Additionally, there was a significant difference between males and females for mean ONSD, whereby males demonstrated a larger diameter (males=0.4860.110 vs. females=0.3530.062cm; p=0.018), but there was no significant difference in PI between males and females (males=2.3630.613 vs. females=1.9500.196; p=0.136). Results of this study confirm the relationship between ONSD and PI in a healthy population. While ICP was not directly assessed in the current study, the strong associations between ONSD and PI suggest that their combined assessment may be employed as a tenable surrogate to non-invasively measure ICP when the invasive measure of ICP is unfeasible.
