The inner self-narratives and academic self-perceptions of those with learning disabilities in post-secondary settings
Authors: Mendes Bronze Sofia Alexandra
Published: June 2021

The purpose of this study was to explore the various disabled identities of those with learning disabilities in higher educational settings, and its impact on academic self-worth. The majority of scholarship has essentialized both disabled identity and academic self-perception, fostering the victimization of those with learning disabilities in the pursuit of their education. This study problematized the medical model, viewing disability as an internal and fixed identity, negatively implicating self-worth. In contrast, this study incorporated a critical disability theory, to highlight the social construction of disability, complimented with a postmodernist lens to appreciate the fluidity of identity and perceptions. A narrative methodological approach was utilized to give voice to the experiences and stories of five self-identifying learning disabled students from Ryerson University. The findings of this research suggest that learning disabled student relate to three different types of disability narratives or identities, implicating their academic worth in many ways.
An investigation of the use of transmission ultrasound to guide minimally invasive thermal therapy
Authors: Soleimankhani Elham
Published: June 2021

Minimally Invasive Thermal Therapy (MITT) is an effective way for the treatment of localized cancer and could replace surgery, chemotherapy or radiation. During MITT, high temperatures in the range of 55-95 °C are produced locally in the target tissue or tumour, resulting in localized protein coagulation. A real-time imaging method is required to guide the procedure of thermal therapy. Ideally, this imaging modality should be noninvasive, inexpensive and easily used and interpreted. It is known that acoustic attenuation is sensitive to both the tissue temperature and the structural changes due to protein coagulation (the endpoint of any thermal therapy treatment) during thermal therapy. Transmission ultrasound imaging is a real-time imaging modality which measures the attenuation property of ultrasound. The goal of this work is to demonstrate the potential of ultrasound attenuation imaging during MITT to quantitatively monitor lesion formation dynamics. An important finding of the present study is that the temporal changes in acoustic attenuation during MITT follow a reproducible pattern in albumen phantoms and bovine liver tissue within the range of thermal therapy temperatures. After heating, the measured attenuation remains higher than the initial amount, suggesting that this irreversible increase is a result of the structural change due to protein coagulation.
Not just the Paris Portraits: preserving Berenice Abbott's glass plate negatives
Authors: Larew Elizabeth
Published: June 2021

This practical thesis project focuses on the preservation of the Paris Portraits series of negatives within the Berenice Abbott Archive at the Ryerson Image Centre. Comprised of 347 gelatin dry plate negatives, this series is unique in Abbott’s body of work and requires additional scholarly research. In order to promote intellectual and physical accessibility to Abbott’s plate negatives, I propose and execute three preservation techniques: rehousing, digitization, and item-level cataloguing. I also provide a brief biography of Abbott’s time in Paris in order to contextualize the collection and discuss the history and deterioration of glass plate negatives.
The hero's journey: tracing the history of the myth to the celebrity
Authors: Goldberg Lisa
Published: June 2021

The terms "hero," "heroism," and, more recently, "heroine," are broad, wide ranging, and contested terms prominent within academia yet there remains a general consensus that heroes are, historically, an essential component to society. This paper will identify that there are diverse Western cultural conceptions surrounding the hero. It is therefore important to trace the meaning behind the concept and draw conclusions as to whether or not the hero narrative has developed or shifted over time. Through an intensive review of the literature on the "hero," this research paper critically identifies the historical constructions, empirical observations, and theoretical analyses in order to explore and understand how the hero narrative has changed or retained timeless qualities of meaning or myth. As the hero developed from the Classical times to the present, through the periods of oral tradition to electronic media, those who are identified as a "hero" became more and more far-reaching. This paper constructs several empirical tables that identify similarities and differences concerning how Western society's classification of heroes has developed. By taking into account the different types of heroic figures that have existed across time, including Greek gods, soldiers, community workers, and celebrities, this paper establishes whether or not the conception of the "hero" changes depending on war, gender, race, popular culture, historical time period, and changes in communication technology.
What to expect? : examining the role of pre-departure cultural orientations
Authors: Korn Ashley
Published: June 2021

Providing relevant pre-migration information for newcomers to Canada can have many potential benefits, however there is a gap in understanding the implications of pre-departure cultural orientations (P-DCO) on refugee settlement. This research focuses on the unique resettlement experiences of privately sponsored refugees entering Canada through the Student Refugee Program (SRP). The purpose of this research is to understand how P-DCO impacts the resettlement of SRP participants and identify the effectiveness of such programs. The study uses the theoretical lens of cultural and social capital to understand the role of P-DCO in the migration and resettlement of SRP participants. Individual interviews were conducted with 6 SRP participants, as well as a key informant interview with the SRP Senior Program Officer. This exploratory study contributes to an enhanced understanding of the effectiveness of P-DCO for refugees in their resettlement and advocates further research for other immigrant categories.

Authors: Narasingavel Ganendran
Published: June 2021

Since the introduction of DSP blocks in commercial FPGAs such as Altera Stratix II and Xilinx Virtex II, DSP applications are increasingly being implemented on FPGAs. This project imprlements a pipelined digital FIR filter with programmable coefficients in an Altera Cyclone II FPGA. An automated test system is also constructed to verify the design. The project places equal emphasis on implementing a programmable FIR as well as building an automated test system, Also, we will evaluate the practicality of the design by comparing the design to the FIR IP core provided by Altera.
Lightweight Self-consolidating Concrete: Statistical Modelling, Mixture Design And Performance Evaluation
Authors: Lotfy Abdurrahmaan
Published: June 2021

A response surface method based experimental study was carried out to model the influence of key parameters on properties of Lightweight Self-Consolidating Concrete (LWSCC) mixtures developed with various types of lightweight aggregates namely, furnace slag (FS), expanded clay (EC), and expanded shale (ESH). Three key parameters were selected to derive mathematical models for evaluating fresh and hardened properties. Water/binder ratio of 0.30 to 0.40, high range water reducing agent (HRWRA) of 0.3 to 1.2% (by total content of binder) and total binder content of 410 to 550 kg/m3 were used for the design of LWSCC mixtures. Slump flow diameter, V-funnel flow time, J-ring flow diameter, J-ring height difference, L-box ratio, filling capacity, bleeding, fresh air content, initial and final set times, sieve segregation, fresh/28-day air/oven dry unit weights and 7- and 28-day compressive strengths were evaluated. Utilizing the developed model, three optimum LWSCC mixes with high desirability were formulated and tested for mechanical, mass transport and durability characteristics. The optimized industrial LWSCC mixtures were produced in lab/industrial set-up with furnace slag, expanded clay, and expanded shale aggregates. The mixtures were evaluated by conducting compressive/flexural/split tensile strength, bond strength (pre/post corrosion), drying shrinkage, sorptivity, absorption, porosity, rapid chloride-ion permeability, hardened air void (%), spacing factor, corrosion resistance, resistance to elevated temperature, salt scaling, freeze-thaw iv resistance, and sulphuric acid resistance tests. It was possible to produce robust LWSCC mixtures that satisfy the European EFNARC criteria for Self-Consolidating Concrete (SCC).

The proposed mix design model is proved to be a useful tool for understanding the interactions among mixture parameters that affect important characteristics of LWSCC. This understanding might simplify the mix design process and the required testing, as the model identifies the relative significance of each parameter, provides important information required to optimize mix design and consequently minimizes the effort needed to optimize LWSCC mixtures, and ensures balance among parameters affecting fresh and hardened properties.

LWSCCs with FS, EC and ESH lightweight aggregates can reduce the construction pollution, increase the design solutions, extend the service life of the structure and hence, promote sustainability in construction industry.
Imagining the farm: spectacle, nationalism, and agri-tourism in Canada
Authors: Poetker Karen
Published: June 2021

"My decision to explore the spectaclization of rural and farm life in Canada was fuelled by the desire to answer the following questions: 

What motivates the nostalgia and the longing that people have for farming, pioneer and rural life?

Why are people longing for this? What is it about modernity that is so disrupting and fragmenting that people would pay money to visit an old farm, to milk a cow, to pick some apples? 

How are farm tourism and nationalism connected? Is the farm as tourist site a physical manifestation of the desire to locate a strong national identity?

What are the implications and complications of this transformation of the farm? 

The nature and length of this research paper is insufficient in dealing with the topic of farm tourism in all its detail. Rather than offer a conclusive discussion on the nature and implications of farm tourism, I hope this paper will bring to light issues of local and rural manifestations of nationalism, otherness, longing and fragmentation as well as call attention to the implications and complications that potentially arise out of agri-tourism" -- From Introduction, page 4.

Victim Age Polymorphism In Stranger Serial Sexual Offences
Authors: Stephens Skye
Published: June 2021

Victim age polymorphism describes a subset of serial sexual offenders who offend against victims from multiple age groups (Guay, Proulx, Cusson, & Ouimet, 2001). Research on victim age polymorphism is an important area of study as polymorphic offenders have been found to have high recidivism rates (Parent, Guay, & Knight, 2011). The current study provided an exploration of polymorphism in 72 sexual offenders who committed 361 stranger offences. Polymorphism occurred in 36% of offenders’ sexual offence series, with the majority of polymorphic offenders victimizing minors aged 11 to 14. In comparison to age specific offenders, polymorphic offenders were found to be a) younger at the start of their sexual offence series, b) more opportunistic, c) less concerned with victim characteristic, d) more likely to be antisocial, and e) a trend was observed that suggested they were more likely to show deviant arousal to rape. These results will be discussed within the contexts of Investigative and Forensic Psychology.
Media and transnational social movements : a content analysis of The Globe and Mail's coverage of the 2009 Tamil protest in Toronto
Authors: Peter Dorris
Published: June 2021

By using theoretical frameworks of Medium theory and New Social Movement Theory, this study analyzed how The Globe and Mail news articles published from January to May 2009 depicted the transnational social movement efforts of the 2009 Tamil protest in Toronto. The method of content analysis was applied to the following research question: How do new articles from The Globe and Mail newspaper portray the transnational social movement (TSM) efforts of the Tamil Diaspora in Canada? This study found that (1) overall there was a negative coverage of the Tamil transnational social movement; and (2) the emphasis was mostly placed on the Tamil protest's alleged affiliation and support for a banned terrorist group. This paper will conclude that the news articles of The Globe and Mail presented a distorted message of the Tamil protest in the articles to attract readership rather than inform the audience, in a neutral method, about the protest events that were occurring at that time. Hence, future research should seek to expand on this study by doing a longitudinal and comparative analysis of the relationship between media and the Tamil transnational social movement.
An Investigation Into The Comparability Of Common Jet Engine Materials With Next Generation Biofuels
Authors: Yoon Paul
Published: June 2021

Growing concerns regarding the environmental impact of burning fossil fuels and energy independence has spurned the transportation industry into developing a more eco-friendly and sustainable way to travel. The most promising frontier in this endeavor is the development of alternative fuels that will significantly reduce the carbon footprint of our current engines with little or no modifications required. The effect that one of these frontier fuels may have, camelina based biofuel, on various fuel system materials was evaluated in this report in accordance with ASTM D4054 in the form of a 50:50 mixture. The materials went through an immersion process at varying temperatures and tested under the numerous standards outlined by the American Society for Testing and Materials (ASTM). The results were compared to a benchmark Jet A1 fuel since the effects of this fuel on current fuel system materials is extensively known. The purpose of this research is to determine the viability of using a 50:50 biofuel mixture in current aircraft fuel systems by evaluating the physical properties after being fuel treated. The results showed that the biofuel mixture affected the non-metallic materials in varying degrees, while not affecting the metallic materials.
Demystifying immigrant youth representations : a look at mainstream and immigrant perspectives within literature and media
Authors: Kawahatsu Carrie Natsu
Published: June 2021

Firstly, this paper analyses two mainstream films, Gran Torino and Entre les Murs (The Class) and looks at how depictions of immigrant youth are often negative and perpetuate stereotypes and racist ideologies. Through the lens of whiteness, I will argue that mainstream media plays an important role in maintaining white hegemony by othering people of colour, in particular, immigrant youth. Secondly, the paper analyses immigrant produced media and literary works and explores how they can offer powerful narratives that critique and analyze issues of social inequality. Utilizing Freire's idea of "conscientization", I contend that youth learn to raise awareness of oppressive conditions in their community and problematize those conditions within society. The counter-narratives that immigrant youth develop refute "othered" identities by moving the focus away from the white dominant voice.
Sharing dance: a participatory action research project in online community dance education
Authors: Lefebvre Julia
Published: June 2021

"As a dance and movement workshop leader for over five years I have seen the benefits that dance education offers students first hand. While on tour across Northern Ontario with the Cree language opera Pimooteewin: The Journey, I had the opportunity to share creative dance workshops with students living in remote locations. These students had limited access to dance education and most schools I visited had no integrated dance curriculum. I found this surprising since the inclusion of dance in Ontario public schools is a requirement. Dance was incorporated into the 1993 Common Curriculum and the 1998 Ontario Curriculum (Ministry of Education). Many teachers I spoke with while on tour mentioned they did not have access to high quality, free dance education materials, and did not feel comfortable teaching the subject. This experience drew me to develop an applied research project with Canada's National Ballet School's (CNBS) community outreach initiative, Sharing Dance. Unlike other online dance education organizations, such as the Council for Ontario Dance and Drama Educators (CODE) that works on a subscription model, Sharing Dance offers teachers easy access to dance education materials for free, potentially overcoming location and socioeconomic obstacles"--From introduction, page 1-2.
Traffic engineering friendly request routing in content delivery network
Authors: Nanthakumaran Arun
Published: June 2021

Content delivery over Internet is optimized for low use perceived latency by designing specialized Content Distribution Network (CDN). Content servers are connected through a content switch the distributes client requests among them to achieve load balancing across the servers. The content switch is located one-hop away from the servers. Server load balancing is one factor in achieveing low user perceived latency and improving operational efficiency. Traffic engineering is another factor that is generally and integrated with serverload balancing for CDN optimization. In this thesis we propose a request routing algorithm for a CDN that was designed to integrate server selection and traffic engineering functions in the request routing system. The CDN employs MPLS in the network for traffic engineering. The proposed algorithm optimizes content delivery for user perceived latency by achieving server load balancing and network traffic loan manaement among alternative paths. It also improves operational efficiency of the CDN by eliminating bottleneck paths and increasing utilization of underutilized servers and paths.
Structural Design Issues On GFRP-Reinforced Concrete Bridge Barriers
Authors: Tropynina Ekaterina
Published: June 2021

In the era of bridge rehabilitation, glass fibre reinforced polymer (GFRP) bars are considered an alternative solution to steel reinforcement to eliminate steel corrosion. In this thesis, a new bridge barrier reinforcement layout was proposed incorporating GFRP bars with anchorage heads. However, it was observed that no design provisions or research data in the literature were found to design the anchorage at barrier-deck slab junction. As such, pullout tests were conducted on GFRP bars embedded in concrete slabs, to determine their pullout strength. Also, testing to-collapse of full-scale bridge barrier under static loading was conducted to determine its load carrying capacity. In addition, finite element analysis of the barrier wall and deck slab portion was performed in order to examine the level of accuracy of the specified factored applied moments due to vehicle impact at the barrier-deck junction. The experimental findings qualified the proposed GFRP-reinforced barrier detailing when subjected to simulated vehicle impact loading.
Calibration of highway safety manual predictive models and validation of safety performance functions for Canadian urban/suburban intersections
Authors: Faisal Shahzad
Published: June 2021

In this research, the HSM predictive models for collisions on urban/suburban arterials are calibrated for collision data from the City of Toronto. It has been found that the use of calibration factors for applying HSM models to Toronto intersection data is not appropriate. New collision models are therefore developed by using local data. The HSM and Toronto models are then calibrated to City of Edmonton intersection collision data to determine whether it is better to calibrate HSM models for a Canadian jurisdiction or models from another Canadian jurisdiction. A related aspect of the research is the investigation of models for crash types. There is no safety performance function (SPF) available in the HSM to predict rear end collisions. Instead, rear end collisions are estimated as a proportion of predicted multivehicle collisions. To overcome this deficiency, Toronto data are used in the estimation of models for rear end collisions.
"Sharing power" : representation of visible minorities on the boards of selected immigrant serving agencies in Peel
Authors: Ghassemi-Gonabadi Masomeh Effat
Published: June 2021

This study analyzes patterns of racial minority representation on the Boards of immigrant serving agencies (ISAs) in the cities of Mississauga and Brampton in the Region of Peel, Ontario. Executive Directors of 13 organizations were contacted and asked to provide ethnic, gender, age and educational information on the composition of their Boards and to describe the ethnic make-up of the client populations they serve. Boards were then scored on diversity (numbers of different ethnic members on the Board) and representativeness (a comparison of the ethnic composition of the Boards to the ethnic make-up of the population served by their ISAs). Findings indicate a wide range of scores on both diversity and representativeness. Some Boards are fully homogeneous and unrepresentative of their clients. Others are diverse but unrepresentative, and still others are fully representative of their client populations.
Minimum noiseless description length (MNDL) thresholding
Authors: Fakhrzadeh Azadeh
Published: June 2021

In this thesis, the problem of data denoising is considered and a new data denoising method is developed. This approach is an adaptive, data-driven thresholding method that is based on Minimum Noiseless Description Length (MNDL). MNDL is an approach to subspace selection which estimates bounds on the desired Mean Square Error (MSE). The subspace minimizing these bounds is chosen as the optimum one. In this research, we explore application of MNDL Subspace Selection (MNDL-SS) as a thresholding method. Although the basic idea and desired criterion of MNDL thresholding and MNDL-SS are the same, the challenges in calculation of the desired criterion in MNDL thresholding are very different. In MNDL-SS, the additive noise effects are in the form of samples of a Chi-Square random variable. However, this assumption does not hold for MNDL thresholding anymore. In this research, we developed a new method for calculation of the desired criterion based on characteristics of noise in thresholding. Our simulation results show that MNDL thresholding outperforms the compared methods.

In this thesis, we also explore the area of image denoising. In image denoising approaches, some properties of the image are considered. One of the well known image denoising methods, that outperforms other methods, is BayesShrink. We compare our method with BayesShrink. We show that the results of MNDS thresholding are comparable with BayesShrink in our simulations.
Integrating UMTS and mobile ad hoc networks
Authors: Wu Meng-chieh
Published: June 2021

Although cellular networks such as GPRS (2.5G) or UMTS (3G) have achieved providing both circuit-switching and packet-switching services with wide area coverage, the mobile users are still expecting higher rates and more mobility to satisfy their needs. Integrating current network architecture with other high-speed and low-cost wireless technologies is a key challenge for migrating to 4G. The IEEE 802.11 technology which has been well-developed and widely-used in local area networks seems to be a proper choice for fulfilling users' expectations. Its ad hoc functionality further improves the mobility of the users.

This research proposes an architecture to achieve the internetworking between 802.11 Mobile Ad Hoc Network (MANET) and UMTS. The key approach being applied for intersystem handovers is SGSN signaling and for ad hoc mobility management is the Mobile IP signaling. The main purpose of this research is to retrieve the best effects by integrating these two network technologies. The integration system results several important features: wide area coverage, mobility and quality of service management.
Shear strength evaluation of reinforced recycled aggregate concrete beams
Authors: Haghdoost Roya Shoghi
Published: June 2021

A theoretical study is conducted to investigate the shear behaviour of recycled aggregate concrete (RAC) beams with and without shear reinforcements along with the performance evaluation various Code based/other existing equations in predicting shear strength. In addition, three artificial neural network (ANN) models for shear strength prediction of RAC beams with and without shear reinforcements are developed and their performance validated by using 108 beams from available research studies. Most of the Codes and existing methods underestimate the shear capacity of RAC beams with/without shear reinforcement. However, over estimation of shear strength by Codes/existing methods for about 10% RAC beams needs to be addressed when using such Codes/existing methods for shear strength prediction. All three ANN models are found to predict shear strength of RAC beams. Developed ANN models are able to simulate the effect of shear reinforcement on the shear strength of RAC beams.
Investigation of the Sediment Removal Frequency for Wet-Detention Stormwater Management Ponds
Authors: Richard Rishon
Published: June 2021

The purpose of this study was to develop methodologies for determining the appropriate sediment removal frequency of wet-detention stormwater management facilities. Using data from a wet pond in the Town of Richmond Hill, a sediment accumulation model was developed using the US EPA’s Stormwater Management Model (Version 5). Two different methodologies were then developed and applied to the facility. The first methodology is a real-time tool that provides the required time for sediment removal for a single cleanout cycle. The second methodology is analysis tool that relates cleanout frequency, annual cost and violations over a 50-year planning period. The results showed that the appropriate sediment removal frequency for the pond was approximately 16 to 17 years, and the annual cost of sediment removal ranged from $2,150 to $2,372, depending on the methodology used. It is recommended that these methodologies be considered for the planning and operation phases of stormwater ponds.
Geological data handling using Oracle 3D : a study on data services and management
Authors: Oren Nedim
Published: June 2021

Efficient management of 3D geological and subsurface models require a robust 3D data modeling environment which can provide the necessary functions and flexibility to enable accessing 3D models in a collaborative work environment through the Internet. This allows geoscientists and geo-engineers to work collaboratively for better, informed decisions. Today, there is no data standard that satisfies the entire 3D geological modelling requirement in a collaborative work environment. This thesis presents the result of a research project that focuses on identifying modelling and analytical requirements of geological models and the usability of existing technologies for both database management and applications that allow sharing 3D models in a collaborative modeling environment. Specifically, it examines current 3D data models and how they can fit into the requirements of the 3D geological modeling. Based on identified system requirements, an integrated solution prototype has been implemented that allows large-scale 3D data management and provides real-time Internet access to the underlying 3D models.
A Robust User Authentication Scheme for Wireless Sensor Network
Authors: Ali M. Zulfiker
Published: June 2021

The primary requirements of a secure Wireless Sensor Network architecture are confidentiality, integrity and authentication of users and other participating entities. User Authentication for wireless sensor networks is a fundamental and important issue in designing dependable and secure systems. In this thesis, we have outlined the security model, functional requirements, assumptions and network setup for an authentication scheme in the first phase. Keeping in mind the security requirements as well as the flaws of past authentication schemes, we propose a robust user authentication method that inherits user anonymity, mutual authentication and password changing functionality of previous password-based schemes and improves security by resisting gateway bypass and replay attack, and many logged in user with the same ID threat. Our scheme is a variant of strong password based schemes that does not require strict network synchronization.

In the second phase of the thesis, we have analysed our authentication scheme from the perspective of security issues and functional requirements. The proposed scheme is modelled in SystemC. It is evaluated in different attack scenarios. The authentication latency, memory and functional requirements, and computational overhead are the metrics used to evaluate the scheme. The effect of multiple users on authentication latency in our scheme is also studied.

Some of the past representative schemes have also been modelled and evaluated in the same environment. A detailed comparison of over-head cost, authentication latency and security features are provided in this thesis. It is verified and confirmed by modeling that our scheme provides enhanced security without adding extra computation at the sensor node.
Experimental study on the structural behavior of insulated sandwich foam-timber panels under combined axial compression and bending
Authors: Mohamed Mahmoud
Published: June 2021

Structural Insulated Panels (SIPs) can significantly reduce emissions produced by our homes and commercial buildings by reducing the amount of energy used for heating and cooling. A SIP is composed of expanded polystyrene insulation (EPS) board laminated between two oriented-strand boards (OSB). SIPs are used all over the world because of their superior strength and quality build. The objective of this thesis it to evaluate the effectiveness of the foam core in providing composite action in SIPs under axial and bending loads to meet both the strength and serviceability requirements. This thesis presents the experimental program and the results of 32 full-size panels tested to-collapse at the Structures Laboratory of Ryerson University. The data generated from this extensive experimental program can easily be used to determine the load carrying capacity of the SIP walls when subjected to axial compressive loading or combined axial compressive loading and bending moment.  
Experimental Investigation on Pull-out Strength of Pre- and Post-Installed GFRP bars for Bridge Barrier Construction
Authors: Abolghasem Alireza
Published: June 2021

This study aims at providing research information on the pullout capacity of straight and headed-end GFRP bars embedded in bridge deck slab as pre-installed anchors for new bridge barrier-deck construction and as post-installed anchors for the replacement of deteriorated bridge barriers. In Phase I of this research, the pullout capacity of pre-installed ribbed-surface GFRP bars in twin- and triple-bar groups were investigated experimentally, considering different bar size, spacing and embedment depths. In phase II of this research, the pullout capacity of post-installed sand-coated and ribbed-surface GFRP bars were investigated experimentally considering different bar size and embedment depths and adhesive types. The experimental findings were compared with available experimental results and pullout formulas. Design values for the pullout strength of the GFRP bars as pre- and post-installed anchors in concrete were deduced.
Through the Lens of Fashion: an Analysis of the Clothing Styles of Women In Early Victorian Ontario
Authors: MacKay M Elaine
Published: June 2021

The stories of the women who lived in and contributed to the growth of early Victorian Canada have been largely untold. Often named only as an adjunct to male heads of households, women have been nearly invisible in the history of this nation. This research project is a study of the women and their dress from 1840 to 1860 as seen through daguerreotypes. It verifies that sitters showed a high level of consistency in their choice of style, fabric, and accessories, but exhibited individuality and personality within the confines of popular fashion. Using information gleaned from the photographs, this examination identifies signs and symbols that were part of the philosophy of early Victorian Canada. As a scholarly document, it provides a series of images that can be used to establish the timelines of Canadian dress and a firm base upon which to build a greater knowledge of Canadian fashion.
Durability of concrete exposed to magnesium chloride anti-icing chemicals
Authors: Sutherland Sherry
Published: June 2021

The objective of this study was to determine if/how magnesium chloride (MgCl₂) influences the durability of typical sidewalk concrete being used in Ontario. The effects of MgCl₂ on deicer salt scaling were reviewed with the hypothesis that MgCl₂ at higher concentrations will cause more scaling. When the early results were inconclusive, the focus of this reearch was then moved to determining if initial exposure to NaCl was a contributing factor, and if the mechanism causing deterioration was due to exposure at high temperatures rather than low temperatures. Mortar specimens were examined for the influence of MgCl₂ on expansion and compressive strength. It was found that MgCl₂ had little effect on deicer salt scaling, but caused an increase in expansion and a decrease in compressive strength with increased MgCl₂ concentrations.
Landfill gas extraction and purification technologies
Authors: Bekmuradov Valeriy
Published: June 2021

The extraction and purification technologies of landfill gas (LFG) from municipal waste continue to generate strong environmental concerns. Historically, the focus of these concerns was an odour in the immediate region of the landfill and the risk of explosions in structures caused by the movement of LFG through soil. While these are still important environmental issues, health risks associated with volatile organic compounds in LFG and damage to the atmosphere through the emission of greenhouse and ozone depleting gases, have also become prominent issues.

The primary objective of this project is to study and examine LFG generation, extraction and purification technologies. Composition of LFG and gas extraction processes is analyzed. Comprehensive literature review of different models for LFG generation rate is provided. The study of LFG extraction and collection systems including design considerations and gas capture schemes are examined. Complete analysis of current purification processes of LFG along with upgrading techniques of methane to bio-methane are carried out. Discussion and recommendation on gas purification methods are conducted relevantly with certain type of LFG composition, level treatment required, quality of LFG anticipated, and its final application.

Accurate portrayals of prior and current LFG extraction and purification technologies will advance the knowledge used to select appropriate waste management and reduction strategies in future.
Determination of thickness and quality of refractory linings in industrial furnaces using acousto ultrasonic echo
Authors: Walters Gary
Published: June 2021

Refractory linings in metallurgical furnaces undergo deterioration and wearing with time. The deterioration is caused mainly by thermomechanical mechanisms leading to cracks, chemical degradation and loss of heat transfer capability. Any sudden failure of the lining is dangerous and could affect the structural integrity of the furnace, leading to production loss and costly refurbishment. Non-destructive testing (NDT) and monitoring of refractory lining would lead to better safety, longer use of the vessel, production optimization, controlled maintenance and increased production. Thickness measurements and monitoring of the refractory lining in operating furnaces is possible using Acousto Ultrasonic -Echo (AU-E) technique. This technique uses stress waves of both acoustic and ultrasonic ranges in order to determine thickness and integrity. This thesis presents the details of AU-E technique in addition to laboratory measurements to determine parameters leading to the in-situ measurements. Finally, three case studies are presented to substantiate the theoretical and laboratory measurements.
The environmental impact of urban land use and transportation strategies in the City of Toronto
Authors: Siddiqui Faisal Mahmood
Published: June 2021

The objective of researchers, planners and engineers is to present to society a viable infrastructure that is sustainable as well as environmentally friendly. Since the growing population, as well as the socio-economic growth of an urban landscape, creates greater and greater travel demands, the effects that these increases cause on our environment and social fabric can not be underestimated. It may appear impossible to devise a plan that will provide a sustainable system, but the crux of the matter is to recognize the importance of this vision as a process. Today, thousands of researchers worldwide are working to develop solid plans and a timeline to implement the many good ideas that have been brought forward.

The development of urban land increases demand for an extensive transportation infrastructure. The impact of land use on transportation, and vice-versa, eventually boils down to its impact on our environment. This project elaborates the inter-connected relationship of urban land use with transportation infrastructure and identifies the regions in the City of Toronto where land-use activities are not compatible with the transportation system. The analysis of this research is based on data from the Transportation Tomorrow Survey (TTS). This paper not only elaborates on these issues but also addresses the requisite improvements that could significantly enhance the quality of the environment for us all in a broader vision of a more sustainable society.
Multilevel neutral point clamped/H-bridge inverters with sinusoidal pulse width modulation
Authors: Shohel Arifur Rahman
Published: June 2021

This project focuses on the topology of multilevel neutral point clamped (NPC)/H-bridge inverters and their modified modulation technique for high-power (megawatts) medium voltage (typically 6000 v) applications. A sinusodial pulse width in-phase disposition modulation is proposed for five-level NPC/H-bridge inverters. The inverter achieves good harmonic performance and low dv/dt in its output voltage waveforms in comparison to the conventional three-level NPC inverter. A seven-level NPC/H-bridge topology and its sinusodial pulse width in-phase disposition modulation are also proposed and investigated, which has better performance than the five-level inverters. Theoretical analysis and computer simulation are carried out for the proposed inverter topologies and algorithms. The output voltage waveforms and harmonic performance are verified by experiments on a five-level NPC/H-bridge inverters.
Collection anthropologique du Muséum de Paris : ethnographic portraits by Jacques-Philippe Potteau
Authors: Sheptytsky-Zäll Juli
Published: June 2021

Jacques-Philippe Potteau, a lesser known photographer and naturalist in nineteenth-century France, produced a series of ethnographic portraits under the title "Collection Anthropologique du Museum de Paris" for the Muséum d'Histoire naturelle in Paris, between 1860-1869. This paper investigates a representative set of the series, found at the Art Gallery of Ontario, which has been used as a source of information for looking at the photographer's mode and scope of production.

These ethnographic portraits, made according to conventions of commercial studio portraiture in Second Empire France, were used for the study and classification of man and displayed as specimens in the Anthropology Collection at the Muséum. By looking at the variation between the most formal and the most sterile compositions, the various presentation methods and the labels as a new source of information, Potteau is identified as a photographer who produced work more independently than previously thought.

A Study on Communication Breakdowns between Native and Non-native Speakers in English Speaking Classes
Authors: Nghi Tran Tin , Khuong Luu Quy
Published: June 2021

English majored students have a positive influence on intercultural awareness in learning a foreign language. In their classes, they are often asked to discuss some academic matters in British cultural beliefs. Although they have a high level of proficiency in English communication, there often encountered misunderstandings between them when they interpret things or present academic matters. As a result, students cannot achieve plurilingual and pluricultural competence in the course. This paper was conducted to investigate communication problems between Vietnamese learners of English and Native teachers at HUFI. The data were collected from 28 participants who are third-year students and four different lecturers from different countries. The findings revealed that sources were mainly clustered for the following reasons: perceptual and language differences, information overload, inattention time pressures, distraction/noise emotions, complexity in organizational structure, and poor retention. The perceptual and language differences, information overload, and emotions were mainly responsible for the quality of communication. This paper can help students engage in awareness-raising activities that promote understanding in some contacts and discussions.
On Being and Belonging: Transnational migration and its bearing on my identity and sense of belonging
Authors: Ragudaran Sanjana
Published: June 2021

Movement of people within or between countries has taken place for millennia. Migration is a common phenomenon, where migrant experiences are known to be vast and varied. Although migration has been studied globally, there is a need to document personal migrant experiences to understand their struggles in order to build inclusive communities. This narrative describes the author’s transnational experiences and struggles in trying to grapple with her identity and sense of belonging.

A obesidade abdominal está associada a um aumento exponencial no risco de morbimortalidade, visto que o padrão de distribuição de gordura corporal é o fator de risco mais significativo em processos mórbidos do que a obesidade generalizada. Estimar a prevalência de obesidade abdominal e identificar os fatores associados. Estudo piloto, descritivo transversal, com abordagem quantitativa. A amostra por conveniência foi constituída por 50 indivíduos com idade entre 18 a 50 anos. Inicialmente foi realizada avaliação antropométrica dos participantes e posteriormente a aplicação de um questionário para definir o perfil e hábitos da população com circunferência da cintura alterada (≥ 88cm para mulheres ou ≥ 102 cm para homens). Os dados foram analisados por meio de estatística descritiva e regressão linear utilizando-se o software Epi Info™. Dentre os participantes 58% (n=29) apresentaram obesidade abdominal. As variáveis que apresentaram significância (p-valor ≤ 0.05) com a obesidade abdominal foram: ser casado, não ser da raça branca, ter 8 anos ou mais de escolaridade; ter IMC indicativo de sobrepeso e obesidade generalizada e não consumir bebida alcóolica. A obesidade abdominal bem como a obesidade generalizada, constitui-se como um grande desafio a ser trabalhado pelos profissionais da saúde, considerando que uma fração significativa da população se encontra nessa circunstância. Nessa perspectiva, a prevenção e o controle da obesidade abdominal devem prover ações que auxiliem os indivíduos na adoção de estilo de vida saudável.
Políticas de formação de professores a distância no Brasil: Os fatores estruturantes da Educação a Distância e Universidade Aberta do Brasil
Authors: Santos Neto Vicente Batista dos
Published: June 2021

O presente trabalho discute a formação de professores no Brasil por meio da educação a distância, tendo como objeto de análise o Programa Universidade Aberta do Brasil. Trata-se de um recorte da tese de doutorado de 2019 intitulada: “a formação inicial de professores a distância no Brasil: os contornos e trajetórias do Sistema Universidade Aberta do Brasil na região do Triângulo Mineiro e Alto Paranaíba no período de 2013 a 2018”. A pesquisa foi apoiada no método materialismo histórico dialético, tendo como principais fontes a pesquisa bibliográfica e a análise documental de documentos da Capes, Ministério da Educação, acerca do Programa UAB. Constatou-se que as políticas de formação de professores no Brasil foram influenciadas por quatro fatores centrais: os organismos internacionais, a agenda neoliberal, as mudanças no sistema de acumulação capitalista e o advento das tecnologias digitais de comunicação e informação, sobretudo a partir dos anos 1990. Nesse cenário criou-se uma legislação propícia à introdução da EaD no país e, posteriormente, da UAB. Surgiu-se então um movimento para o modelo formação privatista-mercantil com a participação da iniciativa privada e a adoção pelo Estado do Programa UAB como importante lócus de formação de professores no país. Notou-se que o Estado imputou à UAB a necessidade de adoção de mecanismos de redução de custos e de precarização do trabalho, com consequente massificação da formação de professores.
