Muslims, Soccer, and the Politics of National Identity
Authors: Aulaqi Arwa
Published: June 2021

Athletes are among the most visible representatives of nations: the nations’ traditions, histories, values, and identities are condensed into the body of performing athlete, who act as ambassadors for their country each time they set foot on the field. However, when we think of athletes today that embody the nations’ identity, how many of these athletes do we come up with of immigrant or minority background? How many do we come up with that are Muslim? These questions predominantly depend on what countries and which sports we examine. In this MRP, I focus on soccer, and the participation of Muslims in this sport. Using a discourse analysis methodology, studying newspaper sources and theories of national identities, I examine the place of Muslims in the West today, and how their participation in soccer is viewed within the context of on-going evolution of national identities, and, most importantly, whether it is viewed as proof or not of their membership in the nation.
Design and optimization of compliant mechanical amplifiers
Authors: Eskandari Amiraslan
Published: June 2021

Piezoelectric (PZT) actuators are micro motion generators capable of producing a high displacement resolution and low strain with high force outputs. However, due to their relatively short motion ranges, the functions of PZT actuators become limited or infeasible for many of the above mentioned applications. One technique to overcome the mentioned shortcoming is to integrate a PZT actuator with a mechanical displacement amplifier. Such an amplification mechanism can be based on a compliant mechanical displacement amplifier (CMDA). A CMDA has many advantages such as no friction losses, no need for lubrication, no tolerance, and et al. over conventional rotating pinjoint mechanisms. Hence, the primary goal of a CMDA is to achieve a large output displacement in desired direction(s) for a given input displacement generated by a PZT actuator, and to keep a high positioning resolution at the same time.
This thesis describes a complete study on the design, development and optimization of two proposed CMDA’s, one for the use in prostate Magnetic Resonance Elastography (MRE) application, and the other for the use as a planar motion generator mechanism for the application in high precision manipulation systems. The design of the both proposed mechanisms are based on the symmetric five-bar topology which facilitates a high amplification ratio (AR) with maintaining a relatively high natural frequency (NF).
The first proposed CMDA was designed and optimized to amplify the generated motion of a PZT actuator in only one direction with keeping the NF as high as possible. On the other hand, the design and optimization of the second proposed CMDA was done to convert the linear motions of the integrated PZT actuators into a XY planar motion with high accuracy and resolution. In this study the comprehensive FEM analysis and simulations of both proposed CMDA designs are provided.
The photographic negative as a historical object : an analysis of the Henryk Ross Łódź ghetto collection at the Art Gallery of Ontario
Authors: Bolanos Lindsay M.
Published: June 2021

The Photographic Negative as a Historical Object: An Analysis of the Henryk Ross Łódź Ghetto Collection at the Art Gallery of Ontario examines the photographic negative, with specific attention to the negative as a historical document. Through an analysis of Jewish photographer Henryk Ross‟ photographic archive, this discussion considers the negative as a historical object by addressing the production, use, dissemination and preservation of the negative using select samples from the 3,000 35mm gelatin silver negatives in the collection, along with Ross‟ 1960s publication Darkam ha-a¸Æaronah shel Yehude Lodz' (The Last Journey of the Jews of Łódź), and Martin Parr and Timothy Prus‟ 2004 Łódź Ghetto Album. By acknowledging the use value of the negative, this thesis focuses on the unique qualities of the photographic negative as a research tool, bringing forth new components to the history of this rare collection. 
Punjabi Immigrant Women In The GTA Truck Industry: A Case Study
Authors: Gill Bashinder
Published: June 2021

The main purpose of this qualitative case study was to explore the growing phenomenon of Punjabi immigrant women from the GTA entering the male dominated trucking industry. In particular, this study aimed to explore the factors that enabled immigrant women to enter a nontraditional occupation and to examine the role of social capital in impacting their labour market outcomes. By interviewing 8 Punjabi immigrant women who have experienced driving a truck, the results of the study showed that living in an extended family household and the support of spouses played a major role in facilitating entry into the truck industry. Furthermore, the accumulation of social capital within Punjabi ethnic enclave communities also enabled women to enter trucking. Drawing on existing literature and government publications concerning the trucking industry, this study also helps to illustrate how immigrant populations become significant actors within particular industries, in this case, the GTA’s trucking industry.
Creating hope : psychosocial intervention for young children infected and affected by HIV/AIDS
Authors: Wilson Natalie
Published: June 2021

Young children who are infected and affected by HIV/AIDS are at risk for psychosocial difficulties due to the confounding variables associated with the diagnosis. Research is needed to understand what makes psychosocial intervention successful for children who are infected and affected. An ethnographic study of an intervention program in the Southern United States was conducted in an attempt to understand what makes this intervention successful from the perspective of the children, their caregivers, and their intervention providers. Interviews and observations with all three groups took place over a three week period. Results were analyzed from both an ecological and a child rights perspective, which suggest that combining social services with a childcare program, the implicit ecological perspective of staff and their knowledge of HIV-related variables, and the development of positive relationships are essential components of a successful program. Recommendations for effective practices are made, and future research needs are discussed.
A comparative study on the performance of different types of wallslab connections in liquid containing concrete structures
Authors: Atashi Nima
Published: June 2021

Waterstops are commonly used at cold joints in construction of liquid containing concrete
structures. A common issue with application of waterstops, is their conflict with top layer of slab
reinforcements. A common solution is to form an upturn part that raises the waterstop clear of the
top slab bars. However, effects of these different types of construction joints on the performance
of structures have not been investigated. To that end, full-scale wall-slab specimens, each
representing a different type of construction joint, are built and tested under different monotonic
and cyclic loadings. The performance of these specimens is compared with regards to first
cracking, limit state capacity and leakage. Results of the tests show that conventional flat joint,
behaves more rigidly compared to other types of joints. A non-linear finite element analysis of a
typical wall-slab specimen, is also presented and its results are compared with the results of the
experiments.
What is the Food Network feeding us? : questioning the Food Network's representation of the food industry
Authors: Kornik Sarah
Published: June 2021

Today, the television Food Network is one of the most popular sources of food knowledge. Although it may be perceived simplistically as a recipe resource for aspiring home chefs it represents much more. Through analyses of the Food Network programming this work examines the network's representations of our food ways. More specifically, portrayals of the food industry are explored. It is argued that the network is steeped in nostalgic longing for a traditional value system which emphasizes family and home. This focus on family, community and small scale food preparation eliminates problematic aspects of our food production, distribution and consumption systems.
Value Drivers For Smart Service Technology
Authors: Halloran Lauren
Published: June 2021

The service industry is rapidly expanding. Organizations that do not innovate through services will be unable to effectively compete in the current marketplace (Bitner et al., 2008). In response, OEMs have developed smart services. Smart services are preemptive actions that are taken by the manufacturers of connected devices based on information collected from sensors embedded in the machines. The success of this service innovation depends on the vendor’s ability to understand and address its clients’ value drivers (Spohrer and Maglio, 2008). This study attempts to understand the factors that lead a customer to value and adopt smart services in the building efficiency industry. The results will show that smart services in the building efficiency industry are valued when the offerings are appropriate for a client’s size; improve on existing decision making technology; are easy to implement; and are believable and reliable.
A review on state-of-the-art practices and research of using GIS in transportation corridor planning
Authors: Yousafzai Khushnud A
Published: June 2021

Transportation corridor planning is a process that is in nature collaborative with local governments and includes extensive public participation opportunities. A corridor may be divided into logical, manageable smaller areas for the purpose of corridor planning. The planning process looks at the existing transportation system within the corridor and how the system could be changed or expanded to meet long-term needs, and includes discussion of existing and projected travel patterns and social, environmental, and economic issues within the corridor. It includes discussion of infrastructure improvements in combination with wise land-use and systems-management actions. GIS is assessed as [an] advanced tool because of the spatial nature of transportation planning and the determination of a range of potential outcomes. The research is intended to investigate the state-of-the-art technology with a goal of greatly improving [the] corridor planning process together with understanding of GIS capabilities, data awareness and accuracy, decision-making and communications. GIS is utilized as a tool in such a way to enhance the ability to accurately predict and easily understand these capabilities. Its main motivation is to better represent GIS in the corridor planning process. It is intended to provide transportation organizations, planning practitioners, and transportation decision-makers with GIS tools and guidance for planning, organizing, and managing to effectively support transportation investment decisions tailored to the specific conditions and performance needs for major transportation improvements. This research proposes to address the capabilities of GIS in corridor planning and enhance the ability to accurately predict and easily understand these capabilities.
Design and optimization of CNC based polishing process
Authors: Lambie James
Published: June 2021

In recent years many aerospace manufacturing corporations have taken an initiative to eliminate the manual interaction of workers and moving work pieces. At the same time there is an ever-increasing demand for efficiency in the manufacturing sector. The research performed investigates the design and development of passive compliance polishing tools for both external and internal polishing of parts on a CNC turning center. The goal of this thesis is to develop tools that meet new safety demands while at the same time optimizing the tools through the Taguchi method and process planning in order to meet quality standards cost effectively. Experiments on both test pieces and production parts were conducted not only at Ryerson University but at Messier-Dowty as well.
Wavelet application in acoustic emission signal detection of wire related events in pipeline
Authors: Wu Ran
Published: June 2021

This thesis establishes an automatic classification program for the signal detection work in pipeline inspection. Time-scale analysis provides the basic methodology of this thesis work. The wavelet transform is implemented in the program for filtering out the majority of noise and detect needed signals. As a popular nondestructive test, acoustic emission (AE) testing has been widely used in many physical and engineering fields such as leak detection and pipeline inspection. Among those applied AE tests, a common problem is to extract the physical features of the ideal events, so as to detect similar signals. In acoustic signal processing, those features can be represented as joint time frequency distribution. However, classical signal processing methods only give global information on either time or frequency domain, while local information is lots. Although the short-time Fourier transform (STFT) is developed to analyze time and frequency details simultaneously, it can only achieve limited precision. Other time-frequency methods are also applied in AE signal processing, but they all have the problem of resolution and time consuming. Wavelet transform is a time-scale technique with adaptable precision, which makes better feature extraction and detail detection. This thesis is an application of wavelet transform in AE signal detection where various noise exists. The wavelet transform with Morelet wavelet as the mother wavelet provides the basis of the program for auto classification in this thesis work. Finally the program is tested with two industrial projects to verify the workability of wavelet transforms and the reliability of the developed auto classifiers.
Transnational resistance or cultural exotica? : interrogating the multicultural accommodation of the Kufiya
Authors: Salem Nashwa
Published: June 2021

The paper focuses on the incorporation of kufiya in Canada as a case study to argue that the coded aesthetics of dress is a salient non-verbal political signifier that marks transnational identities of resistance. However, its resistive communication is ruptured and dehistoricized by its incorporation into the hegemonic zone of multicultural Canada. Paradoxically, multiculturalism's disembodied production of the kufiya is further appropriated and commodified by mainstream countercultures as exotic chic through an Orientalist frame.

The paper analyzes the cultural appropriation of the kufiya as a political practice whereby it concurrently operates within and naturalizes unequal power and social relationships. The processes that enable dominant groups to access, possess and (re)define cultural productions of marginal social groups are interrogated. This examination is extended to assessing the implications cultural appropriation has on the kufiya as well as appropriated communities of resistance.
Flexible Pavement Performance Evaluation in Ontario: an Overview
Authors: Hassan Muzaffar
Published: June 2021

Measuring pavement performance is a major component of the pavement management system. It assists in decision-making for finding the optimum strategies to provide, evaluate, and maintain serviceability in an acceptable condition cost effectively. The Ontario Ministry of Transportation (MTO) has been systematically rating pavement performance since the mid-1960s. Pavement condition survey involves measurement of two physical parameters: ride quality of pavement surfaces, and the extent and severity of pavement distress manifestations. The pavement ride quality can be measured with an acceptable level of consistency and repeatability through automation. However, achieving consistency in the evaluation of pavement distress manifestations is a challenging task because the automation that could accurately and consistently detect, quantify and record surface distresses is not fully developed is spite of rapid advances in video imagery and non-contact sensing devices. This report evaluates the progress made over the past three decades in the key areas of Distress Manifestation Index, Riding Comfort Rating, Pavement Condition Index and second generation Pavement Management System (PMS2). A review of the Ministryʼs network-level pavement performance database is presented, emphasizing pavement condition surveys, prediction models and main factors influencing assessment of long-term pavement performance. Several key issues related to the quality control and quality assurance of the pavement roughness are discussed with reference to the verification techniques used by the MTO. Based on the literature review, future recommendations for possible improvements of the prediction models and techniques used for the evaluation of pavement performance are presented in order to obtain more consistent values.
Pavement Evaluation Strategies and Ways to Improve the Performance of Asphalt Overlays
Authors: Afzal Sohail
Published: June 2021

Highway rehabilitation is a blooming industry in the world and in particular North America. Highway agencies over the years have experienced problems in addressing pavement deteriorations, troubles with underlying pavement materials and management and evaluation of the existing pavements. This study has two objectives. The first objective is to discuss the types of distresses in both flexible and rigid pavements, pavement evaluation methods and equipment in use, pavement condition rating system, process of field investigation, life cycle cost analysis, and pavement selection strategies. A case study of Highway 401 eastbound collector lanes (from Avenue Road to Highway 404) was carried out to demonstrate the process of pavement evaluation and design. The second objective is to undergo an experimental program to evaluate the potential use of shingle waste into Superpave 19.0 and 12.5 asphalt mixes. The evaluation of volumetric properties of the mixes was performed. The trials demonstrated that volumetric properties of the mixes can be achieved at a lower asphalt content. Performance of mixes containing shingles was evaluated through various Highway agencies proved that incorporation of shingles enhances the performance of HMA mixes by improving durability, and increasing rutting resistance, while achieving comparable fatigue resistance.
GIS-Based Hydrological Modelling in the Toronto Region
Authors: Li Riuqiu
Published: June 2021

The urbanization changes a watershed's response to precipitation. The most common effects include the reduced infiltration and the decreased travel time, which significantly increase runoff and peak discharges. This study attempts to analyze the impact of land use on runoff in the Toronto Region. In this report, the focus is on two aspects: (1) generating watershed boundaries using digital elevation model (DEM) data with the help of HEC-HMS, and (2) calculating runoff in the study area using the United States Soil Conservation Service (SCS) curve number method for the early 1990s and 2003. The study is based on the watershed boundaries generated from DEM data with 10 m resolution. Because of the flat surface in the south of the Toronto Region, the areas of the watersheds generated in this study are slightly less than the real ones, but the difference is within acceptable range. As a crucial parameter in the SCS method for runoff calculation, curve number is difficult to obtain. In this project, curve numbers for each watershed are calculated by using the land cover and soil data of the early 1990s and 2003 respectively. According to the theory, the higher the curve number is, the higher the potential of runoff generation in the area is. Unlike what is expected, the curve numbers have changed little from the early 1990s to 2003, although the impervious surface has increased. This is because the variation of the land cover is too little to increase the curve numbers. The curve number for each watershed is a weighted one. If the area of a specific lot which has changed from pervious to impervious surface is small, the weight variation of such area is also small. The other reason for the little change of curve numbers is that the land cover data sets of the early 1990s and 2003 used different classification systems. To eliminate the discrepancy resulting from those land cover classification systems, the curve numbers in 2003 were calculated by referring both classification schemes of the early 1990s and 2003. Because the land cover classification in this study is reasonable, the curve number of the Toronto Region in 2003, 80.4 can be used in the future research.
Memory access behavior of dynamically allocated data structures and programs with irregular access patterns
Authors: Yu Zhen
Published: June 2021

With the development of modern computers, memory latencies have become a key bottleneck for the performance of computer systems. Since then, much research work has targeted improving the performance of memory hierarchy. In this thesis, we examine the behavior of dynamically allocated data structures (DADS) and programs with irregular access patterns (PIAP). DADS and PIAP use dynamic memory management or algorithms with unpredictable behaviour. By simulating some applications of dynamically allocated data structures (DADS) and programs with irregular access patterns (PIAP), it is found that general cache management policies can not effectively use the treasurable cache resources for DADS and PIAP. We explored the use of mathematical formula applied to signal processing to improve the performance of memory hierarchy.
Experimental Investigation Of Nanostructures Generated On Glasses Using A MHz Femtosecond Laser
Authors: Vipparty Dheeraj
Published: June 2021

This dissertation reports the synthesis of unique Si0₂ based nanostructures by exposing glass samples to MHz repletion rate femtosecond laser irradiation. A three-dimensional fibrous nanoparticle agglomerate network was observed on soda-lime glass (73% SiO + other compounds) when exposed to femtosecond laser irradiation at 8.4 MHz and 12.6 MHz repetition rate and 0.5 ms dwell time, in air. By irradiating silica glass (96% SiO₂+ trace elements) sample under ambient conditions with femtosecond pulses at 12.6 MHz and dwell time in excess of 3.0 ms; long continuous nanofibers of extremely high aspect ration (certain fibers up to 100000:1) were obtained. The mechanisms that promote such nanostructures with distinct morphologies have been explored. A deeper insight into the fundamentals of femtosecond laser interaction with dielectrics led to the understanding that variations in bandgap alters ablation dynamics and dictates the response of glass to femtosecond laser irradiation, ultimately resulting in the formation of structures with dissimilar morphology on silica and soda-lime glass.
An evaluation of Ontario public health units' practices in the redevelopment of brownfields
Authors: Lachapelle Barbara
Published: June 2021

The revitalization of brownfields provides many health benefits. Revitalization addresses historical contamination and it allows to re-design the community with health in mind. It is recognized that public health units (PHUs) have an important role to play on brownfield sites. Information suggests that Ontario PHUs often become involved on brownfield sites but the extend of that involvement is not known.
Ontario PHUs were surveyed about their involvement on brownfield sites. The results indicate that most Ontario PHUs engage in brownfield redevelopment to some extent. Public health units identified inadequate resources, expertise, and lack of training as the most critical factors affecting their response.
Results of the survey were further compared with the ATSDR Brownfields/Land Revitalization Action Model. This critical analysis helped to identify key gaps and weaknesses in the current Ontario practices. The results are used to propose recommendations to enhance public health practice and to maximize community health benefits.
The Meaning Of A Moment : an Analysis of the Photomicrographs of Dr. Max Poser in Response to Their Physical Location and Trajectory
Authors: Westfall Heather
Published: June 2021

Dr. Max Poser was a researcher, scientist, and lecturer in the fields of ophthalmology and physiological optics at the New York based optics company, Bausch & Lomb. This thesis examines a group of his silver gelatin photographs located at George Eastman House and compares this series of 1930s photomicrographs to other images by Dr. Poser at the Bausch & Lomb archive. This thesis contextualizes the photographs within the history of photomicrography, the biography of Dr. Poser, and his work at Bausch & Lomb to understand why these photographs were made. Several of these photomicrographs were exhibited and published before arriving at the museum, and these frameworks show how the usage of a photograph can change how it is understood. Finally, the thesis examines the physical locations where each of the objects is kept and how those locations generate different connotations that reflect the mission of each institution.
Environmental Restoration Of Concrete Flood-Control Channels
Authors: Fan Celia W.M.
Published: June 2021

Many rivers and streams throughout the world in the past century were severely affected by human activities including water extraction, watershed land use changes, power generation, dam and levee construction. In highly urbanized cities, engineering practices advocate straightening, enlarging, and converting the natural rivers and streams into concrete channels to minimize flooding and erosion problems. These engineering design approaches destroy the natural equilibrium of the fluvial systems and eliminate the aquatic and riparian species in the watercourse. The objective of this research is to develop a general stream restoration design approach for flood control concrete channels in highly urbanized areas. The restoration goals are: 1) to create a natural and self-sustainable river system in order to re-establish the aquatic species on the flood control channel; 2) to provide appropriate in-stream covers, pools and riffles features for fish spawning and rearing; and 3) to maintain the flood control function after stream restoration.

There are four phrases involved in the design methodology of flood channels restoration: 1) identification of restoration goals, 2) stream assessment on the existing condition; 3) modification and verification of the low-flow channel design based on stream assessment findings; and 4) confirmation of the original flood control function. Yuen Long Nullah in Hong Kong will be used as a pilot site study to demonstrate the design framework. Meanders and deflectors will be applied to the low-flow channel modification design. A physical model representing an actual 2-metre wide meander channel section of the low-flow channel was constructed and experimented at The Hong Kong Polytechnic University’s Hydraulics Laboratory. A numerical sediment transport model using the CCHE2D program was used to adjust the modification design and verify the flood control function. The pilot site has been tentatively demonstrated the restoration design approach developed in this research where deflectors are a major factor on pools creation. Moreover, a single deflector located along the inner curvature of the meander section with 1/3 contraction ratio is proved to be the best design using the physical model. The numerical model using the CCHE2D program showed that the 7-block system can be used to model a deflector with porosity of 40%. Numerical results also demonstrated that the bed material will not be totally flushed out after a severe thunder storm.
Skilled play : positioning the player at the centre of the digital game
Authors: Clemens Chris
Published: June 2021

This thesis argues that a focus on the player and the skill sets required to play video games - a player-skill perspective - provides a productive framework from which to examine and address many contemporary 'problem areas' within game studies. Familiarity, social performativity, and material mastery form three crucial, interlocking junctures where skill and mastery are framed as essential components for undertanding games. The game controller is positioned as a 'gatekeeper' between player and game; a precluding factor in engaging with the medium. Participant responses from original qualitative research, which places a primacy on female voices, are framed within a gaming climate of historically increasing complexification of game genres and material components, and point to several trends in how women can (and do) contend with gendered technology.
Made/maid in the media: narrative discourses surrounding Filipina nannies in the live-in caregiver program
Authors: Edejer Holly Dae
Published: June 2021

This paper explores the various narratives and media representations surrounding Filipinas in Canada’s Live-In Caregiver Program. This study draws upon existing scholarship in global migration of (gendered, racialized, and class-based) domestic labour, as well as theories of postcolonialism and media studies. Using critical discourse analysis, the content of 132 news articles from 1988 to 2014 in the Toronto Star are coded and discussed. The five main categories in which these Filipina live-in caregivers – ‘or Filipina nannies’ – are constructed are identified as foreigners, mothers, workers, victims, and activists. The research findings suggest that representations of Filipina live-in caregivers are framed by notions of difference and social hierarchy in Canada’s most widely disseminated newspaper. Thus this newsprint media discourse reproduces the subaltern status and dual in/visibility of this minority group in Canadian society.
Expanding and facilitating access to the Paul Lewis Anderson photographs at George Eastman House
Authors: Murphy Andrew G.
Published: June 2021

Paul Lewis Anderson (American, 1880-1956) was a photographer, educator, and writer. His career began in earnest in 1909 and, with only one major interruption, he continued to photograph until 1953. During his lifetime, he wrote many articles and books on Pictorial photography and photographic techniques. He devoted his photographic work to Pictorialism. This thesis brings to light the 492 Paul Lewis Anderson photographs at George Eastman House by expanding access with a collection guide. This guide consists of vital information about Anderson and the photographs, explanations of the photographic processes Anderson used, a listing of the photographs according to box, examples of the inscriptions he used, and a selected bibliography for more information on Anderson.
Seeking political inclusion : the case of South Asian political representation in Peel Region
Authors: Matheson Ian Andrew
Published: June 2021

Analyzes the patterns of racial minority political representation in the Greater Toronto Areas and sets out to answer three general questions: Why are the rates of racial minority political representation higher in the suburban centres of Mississauga and Brampton than in the City of Toronto? Why have South Asian politicians succeeded in achieving political office at greater rates than other racial minority politicians? And why are the city councils of Toronto's surrounding suburbs still suffering from greater rates of racial minority underrepresentation? This study concludes that a variety of variables have led to a more favourable suburban political opportunity structure: the faster growth rates and higher residential concentration of South Asian communities, higher rates of affluence among South Asian communities, lower incumbency rates, the 'colour coding' of Peel's federal electoral districts, high concentrations of ethnic civil organizations, and the fear of being labeled terrorists.
The effects of steel reinforcement corrosion on the flexural capacity and stiffness of reinforced concrete beams
Authors: Joyce Timothy A
Published: June 2021

This study is an attempt to derive a relationship between steel reinforcement corrosion and the coinciding loss of flexural strength. The corrosion of the steel was isolated in the flexural region in order to eliminate contributions from stirrup corrosion and loss of bond within the development length. It was determined that the flexural capacity of reinforced concrete beams decreased as the rate of corrosion increased. In addition to the study of flexural capacity, the prediction of the flexural behaviour of corroded beams was studied through the stiffness effects of reinforcement corrosion. The stiffness study indicated a sharp drop in stiffness at relatively low degrees of corrosion, followed by a slower decline at increasing levels of corrosion. Mass loss, crack width and chloride ion content were examined as indicators of degree of corrosion. These relationships are an essential step in developing an effective model for the performance of corroded reinforced concrete beams in the future.
Investigation on the capacity of TL-5 GFRP-reinforced concrete bridge barrier-deck anchorage subjected to transverse vehicle impact loading
Authors: Dervishhasani Gledis
Published: June 2021

A new Ontario-based glass fiber reinforced polymer (GFRP) bar manufacturer developed high-modulus (HM) GFRP bars with headed ends for use in bridge construction. This thesis presents a structural qualification procedure to qualify the use of the developed GFRP bars in concrete bridge barriers-deck joint. The thesis is comprised of two phases. The first phase includes an experimental program to investigate the pullout capacity of the GFRP bar anchorage in normal strength concrete. In phase two, three sets of full-scale TL-5 barrier wall-deck system of 900 mm length were cast and tested to-collapse. The first set incorporated headed-end GFRP bars to connect the barrier wall to a deck slab cantilever for better pre-installed anchorage. The second set is identical to the first set but for non-deformable thick deck slab. The third set incorporated post-installed GFRP bars in non-deformable thick deck slab using a commercial epoxy adhesive. Experimental capacities of the tested specimen were then correlated with factored applied moments given by the 2006 Commentaries of the Canadian Highway Bridge Design Code and available equations in the literature. Based on the experimental findings, conclusions and recommendations were drawn.
Design and analysis of plate anchors in sand
Authors: Waseem Muhammad
Published: June 2021

Plate anchors, as an efficient and reliable anchorage system, have been widely used to resist uplift forces produced by structures, such as transmission towers, offshore platforms, submerged pipelines, and tunnels. In order to design a plate anchor it is important to know the factors which influence the design and uplift behavior of anchors embedded in sand.

In this report a number of model uplift tests and numerical investigations made by different authors are described and based on these readings the uplift behavior of anchors in sand is explored and anchor's design procedure is described. In addition, basic anchor types, failure modes in anchors, and design codes are mentioned.

Based on this study, it is found that the failure plane and uplift capacity is significantly influenced by the soil density and embedment depth. Therefore, it is concluded that the influence of sand density and embedment depth should be considered in anchor design.
Peyi A Pwomet: The Experience of Haitian Refugee Claimants in Toronto
Authors: Pether Sophie
Published: June 2021

This study assesses the current Canadian refugee determination process and Canadian refugee policy by comparing it with the narrative experience of Haitian refugee claimants in Toronto, Canada. The analysis was guided by a critical anti-racist framework and forced migration theory. Qualitative research was conducted by interviewing five Haitian refugee claimants and a Haitian community leader, all living in Toronto. The research found that Haitian refugee claimants face a multitude of barriers when navigating through the refugee determination process. A socio-political history of Haiti is provided to contextualize the motivations and factors which have induced Haitian migration. This study is the first of its kind with regard to research focused specifically on the experience of Haitian refugee claimants in Canada and in particular Toronto. It contributes to the very limited existing research on Haitian refugees in Canada.
Refugee Health: A Gender Comparison in Health Care Access
Authors: Dadey Kate
Published: June 2021

Research suggests that Canada's newly arrived immigrant and refugee communities tend to be healthier than the domestic population, and that their health declines over time. Studies examining immigrant and refugee health primarily focus on how barriers associated with language, the settlement experience, culture, and systemic processes impede the utilization of health services among refugee men and women respectively. However, without the benefit of a gender comparison, such studies fail to identify the variation in health needs and differences in health-seeking between refugee men and women, and are thus limited in their capacity to improve service utilization. Drawing from exiting literature on refugee health status pre-migration and during resettlement, this paper implicates the role of health care reform processes in exploring the gender differences in access and health-seeking. A postcolonial feminist epistemology is advanced as a means to include the voices of refugees and other marginalized groups in future research and practice in order to encourage substantive change.

The fear factor : effects of implicit and explicit processing on the emotional enhancement of memory
Authors: Patel Ronak
Published: June 2021

This thesis examines whether implicit and explicit processing of emotional facial expressions affects the emotional enhancement of memory (EEM). On the basis that explicit processing is associated with relative reductions in amygdala activation and arousal, I predicted that fearful faces, in particular, would lead to a robust EEM effect following encoding with implicit, but not explicit processing. Participants were shown a series of facial expressions (happy, fearful, angry, and neutral) in an "indirect" and a "direct" task designed to elicit implicit and explicit processing, respectively. Later they underwent a recognition memory test using the Remember-Know paradigm. Fearful faces exhibited a unique pattern whereby indirect encoding led to an enhanced subjective sense of recollection, whereas direct encoding prevented an increase in recollection that was observed for all other emotions. These findings may reflect interactions among amygdalar/arousal thresholds and levels of processing (LOP) effects on recognition memory.
Development of a sustainable and inclusive solid waste management system in Colombia
Authors: Edmonds Jessica
Published: June 2021

Managing solid waste is a pressing environmental issue worldwide. This is especially observed in developing countries, where the main concern is to provide the service of waste collection, usually lacking a formal recycling program. Instead, recycling is often conducted by an informal sector composed of recyclers-by-trade. What has been found is that the current informal recycling sector - if approached differently - can offer a financially viable and an environmentally and culturally sound solution. A case study approach was chosen and questionnaires were conducted with recyclers-by-trade and dealers in Cali, Colombia. An interview was conducted with the President of the Recyclers' Association of Bogotá, Colombia. A normative system is proposed as an alternative context-based solution in developing countries that focuses on the inclusion of organized recyclers-by-trade into the formal solid waste management in order to increase recycling rates, extend the lifespan of landfills and improve the living and working conditions of this informal recycling sector.
Collaborative filtering based service ranking with invocation histories
Authors: Zhang Qiong

Collaborative filtering based recommender systems have been very successful on dealing with the information overload problem and providing personalized recommendations to users. When more and more web services are published online, this technique can also help recommend and select services which satisfy users’ particular Quality of Service (QoS) requirements and preferences. In this thesis, we propose a novel collaborative filtering based service ranking mechanism, in which the invocation and query histories are used to infer the users’ preferences, and user similarity is calculated based on invocations and queries. To overcome some of the inherent problems with the collaborative filtering systems such as the cold start and data sparsity problem, the final ranking score is a combination of the QoS-based matching score and the collaborative filtering based score. The experiment using the simulated data proves the effectiveness of the proposed algorithm.
The demise of safety film : a review of the cellulose acetate based negatives in the collection of the Kodak Canada Archive
Authors: Harris Megan Lena
Published: June 2021

The vinegar syndrome, a process in which cellulose acetate based films deteriorate, is becoming a prominent problem within collections worldwide. To understand this phenomenon one must look at the history and make up of cellulose acetate, the chemistry of the degradation process and the steps institutions are taking to stabilize objects to allow future access. With this knowledge, preservation strategies need to be applied to promote longevity. To illustrate this idea, a collection of forty degrading negatives from the Kodak Canada Archive at Ryerson University Library have been used as a case study in which research on cellulose acetate, the chemistry of this material, the vinegar syndrome, and present recommendations for storage have been taken into consideration and used as a basis for a re-housing project. All information and objects are used to argue for the preservation of such objects and the understanding of the importance of the object itself.
Dynamic Bandwidth Management for TCP Flows in a Diffserv-Enabled Mobile Wireless Access Network
Authors: Huang Li
Published: June 2021

With the soaring demand to provide global mobility for wide range of services, a growing trend for wireless access networks is to support multiple radio technologies that can be achieved efficiently by using TCP/IP protocols in the access network. In the thesis, we consider a mobile wireless access network where DiffServ is deployed as the QoS solution and Mobile IP is employed as the handover protocol. We first conducted a study on the impact of handover on DiffServ flows. Then we introduced a transient service level for handover flows and propose our QoS scheme and admission control algorithms for handover flows, which protect local flows from losing bandwidth to handover flows by separating the two flows into different service classes. We also proposed a service upgrade algorithm to upgrade the service level of handover flows based on the dynamic information of bandwidth utilization and different service upgrade priorities. To guarantee the proper provisioning for each service class, we proposed a dynamic bandwidth-provisioning algorithm that allows dynamic adjustment of bandwidth allocations to different service classes by adjusting their respective weights configured at the scheduler. We evaluated the feasibility of our QoS scheme and algorithm by simulating different handover situations and results show that the proposed scheme is viable under variety of provisioning scenarios.
Urban First Nations Men: Narratives of Identity Striving to Live a Balanced Life
Authors: Carter Celina
Published: June 2021

Dominant discourse contains an abundance of negative stereotypical images of First Nations males that are historically steeped in colonial issues. These images are locked in time and can influence both First Nations mens’ sense of self and health care providers’ practices. Using a strength-based perspective and the lens of Two-Eyed Seeing, this narrative study explored the identity of First Nations men living a balanced life in Toronto. Three First Nations men participated in two semi-structured interviews and Anishnaabe Symbol-Based Reflection. Findings indicate that their narratives of identity are focused on positive mindsets and resilience, and that positive First Nations identity is supported by having mentors, knowing family histories, and connecting with healthy Aboriginal communities. Implications of this research for nursing is the need to employ strength-based and postcolonial frameworks, and reflexive practices that reveal biases; this will facilitate nurses to resist racialized stereotypes and discrimination while promoting culturally safe care.
Adapting to born-digital photographs : a case study of the Canadian Centre for Architecture
Authors: Moghtader Saba
Published: June 2021

As born-digital photography collections grow, so grows the need for a more defined set of guidelines on the best practices of how to acquire, describe and preserve said photographs. This paper is the result of a practical project conducted at the Canadian Centre for Architecture. The project uses the CCA as a case study and asks the question: how is the Centre adapting to the collection of born-digital photographs? During a six-month residency, the author, developed and implemented a description guideline, workflow, and donor guideline for the collection and cataloguing of born-digital photographs. These guidelines are the result of the steady growth in the volume of born-digital photographs coupled with the need for ensuring long term preservation for existing and potential collections.

The aim of this paper is to help improve the usefulness and clarity of the guidelines. The case study and paper was conducted in conjunction with the requirements of Film and Photography Preservation and Collections Management (FPPCM) master’s at Ryerson University. The title of the guideline is Guidelines for Describing Born-Digital Photograph.
