Journalistic objectivity and The Daily Show with Jon Stewart
Authors: Parker Ryan Harris
Published: May 2021

The press is a constitutive part of our society. It helps create national identities and formulates society's understanding of itself and its place in the world. Moreover, a free press is indispensable for ensuring the vibrancy of a democracy. For these reasons, a close inspection of news, and an evaluation of its performance, is crucial.

We must look to the development of the mass press at the turn of the twentieth century to locate the beginnings of journalistic objectivity and the type of news we are familiar with today. The first section of this paper offers a review of accounts of this transformational period, placing opposing theories within the larger framework of the frictions between cultural studies and political economy, and underscores the need for a holistic understanding of the period. The second section chronicles the press's articulation of its new professional tenets, offers a definition of journalistic objectivity, and reveals its intrinsic limitations. The third section details how the modern press's ideal democratic mandate has been compromised, with the influence of the press being used instead to ensconce powerful interests. And the fourth section outlines the calls for a redefinition of journalism in light of the failures covered in the preceding section.

Finally, The Daily Show with Jon Stewart is offered as an alternative journalistic form that transcends the dangerous dogma of traditional news outlets, allowing it to fulfill the democratic responsibility of the press by encouraging a critical and astute citizenry.

Reviving Stories And Space Of The Past: Exploring New Opportunities In Mixed Media Storytelling
Authors: Borland Dawsyn
Published: May 2021

This project presents the idea that historic house museums (HHMs) can use Augmented Reality (AR) and physical interactive space to bring stories and characters of the past back to life. Designed to foster self-directed discovery and informal learning of the space and story, this project uses a historically factual AR character to reanimate the sense of human presence within the space. Rather than disrupting the traditional narratives of HHMs, this mixed media storytelling experience extends historical stories by making them more personal and relatable. Using tangible stories, multisensory interactions, and an AR experience to extend the historical narrative, this form of museological work creates more opportunities for empathic character-driven storytelling. Lastly, I identify that this proof of concept could be used in multiple applications, as both a storytelling medium and a communication tool.
The next generation leased line telecommunication protection for high voltage substation
Authors: Hussain Murad
Published: May 2021

Telecommunication circuits and leased lines have been in use for controlling substations for many years. These circuits have usually been engineered according to set standards however recent studies have shown that the parameters used for engineering the telecommunication circuits have various design flaws that may put these circuits. in jeopardy during a local substation fault. The existing protection scheme for SolarI wind and other relevant power generating farms are such that if they lose communication with the local Utility Transmission Station (UTS)I the UTS automatically trips a local breaker and knocks the generation plant off the grid this could mean thousands of dollars in lost revenue for the generation company hence even a minor flaw in the telecommunication circuits can have a significant impact on the substation control system. This case study reviews the challenges of designing these telecommunication circuits for control and monitoring of substations and also reviews the case study performed by Hydro Quebec on the concept of Zone of Influence. In addition this study also proposes an alternate telecommunication model that when implemented will be able to withstand all the challenges of designing a circuits for the high voltage substation.
Simulation of Enzymatic Production of Amoxicillin
Authors: Khan Zafar Uddin
Published: May 2021

This project report is an attempt to find better conditions and reaction parameters for the potential commercialization of the enzymatic production of amoxicillin. A kinetic model from the literature was used to describe a reaction between p-hydroxyphenylglycine methyl ester (PHPGME) and 6-aminopenicillanic acid (6-APA) that is catalyzed by penicillin G acylase immobilized onto glyoxyl-agarose gel beads. A C++ computer program was developed using the Fourth Order Runge-Kutta method to simulate higher substrate and enzyme concentration during the reaction. For model validation, simulation results were compared with experimental data from the literature and fractional errors. This simulation model predicted 24% yield of amoxicillin at high substrate concentration (50mM of 6-APA; 300mM of PHPGME). It also predicted that increasing the enzyme concentration by four fold could produce a similar amoxicillin yield four times faster. The simulation results obtained in this work could be used in the future to aid in optimization and in further modifications of the kinetic model to predict even better yields. This enzymatic process could therefore become an industrial process to substitute the existing chemical route, which contains toxic organic solvents.
"Good" evidence: a critical lens on representations of development and the developing world
Authors: Ferguson Lisa Jean
Published: May 2021

The ethics of conventional representations of the developing world in charity fundraising and photojournalism have been increasingly questioned. Van Leeuwen‘s (2000) social semiotic model of analysis of visual racism, applied to a famine image, reveals strategies for symbolically representing otherness that perpetuate a naturalized ― "Western rescuer/developing world victim" narrative. Respondent interviews demonstrate that such ― "poverty porn" produces viewer apathy, while an alternative representation depicting self-determination evokes a charitable response. Elliott‘s (2003) ethical framework is used to judge the harm of conventional representations. The results, while tentative, suggest worth in expanding the study in light of implications for represented persons, the viewer, and Canadian society. In the meantime, image producers and distributors must become visually literate to avoid using harmful images.
Regulation Of Endocytosis By Ultrasound And Microbubble Treatment: Potential For Controlled Cellular Delivery Of Drugs To Cancer Cells
Authors: Fekri Farnaz
Published: May 2021

The delivery of therapeutics across biological barriers is a limiting factor in achieving ideal pharmacologic responses in patients. Modulating endocytic mechanisms with targeted, clinically-relevant interventions can increase intracellular delivery across biological barriers, and improve the efficacy of drugs. Ultrasound-microbubble (USMB) is a novel targeted delivery strategy that has shown promising potential in both diagnostic and therapeutic applications. The collective behaviour of microbubbles in the acoustic field can increase the plasma membrane permeability of surrounding cells, and enhance the delivery of therapeutics across biological barriers. USMB achieves the intracellular delivery of drugs through sonoporation and modulation of endocytic pathways, but the type of endocytic pathways and the mechanisms of activation were not known. I identified that, under distinct regulations, USMB enhances the rate of both clathrin-mediated endocytosis, as well as a non-receptor-mediated pathway responsible for internalizing bulk fluid into cells. I discovered that lysosome exocytosis and acidsphingomyelinase are required for the regulation of the clathrin-mediated pathway but not fluidphase endocytosis following USMB treatment. Given the potential of the clathrin-independent pathway to form high capacity carries for the uptake of fluids and therapeutics into cells, I aimed to identify the molecular identity of the proteins that drive the formation of non-clathrin coated vesicles following USMB treatment. I established that flotillins contribute to the USMB-induced vesicular uptake of fluid into cells, a phenomenon that depends on palmitoyltransferase DHHC5 and the Src-family kinase Fyn. Furthermore, I confirmed that USMB treatment can enhance the intracellular delivery of chemotherapeutic drugs such as cisplatin, and improve its therapeutic efficacy in a flotillin-dependent manner. This project established that both clathrin-mediated endocytosis and flotillin-dependent endocytosis can be modulated by clinically-relevant USMB treatments to enhance drug uptake and efficacy, revealing an important new strategy for targeted drug delivery in cancer treatment.
Kingfish
Authors: McDonald Kenneth
Published: May 2021

Kingfish is a documentary film that addresses a 19-year estrangement between my father, Jack McDonald, and his brother, Dan. Despite research indicating that 1 in 12 people experience familial estrangement,1 this phenomenon is rarely discussed. Kingfish explores the culture of silence surrounding family estrangement, as well as other complex factors contributing to its initiation and maintenance. To confront this, Kingfish poses a two-part question: How does estrangement function and what are its effects? I examine Jack and Dan’s estrangement as a byproduct of significant events that were not properly addressed or processed. I also look at psychological concepts of differentiation of self and betrayal of the family system, as well as Jack and Dan’s distinct valuation of money. Existing within the tradition of domestic ethnography and autobiographical documentary, Kingfish provides an intimate and personal portrait of family cut-off, which acts as one small initiative to confront the silence surrounding estrangement.
Natural Frequencies of a Manipulator with Rigid Tip Mass: the Case of Flexural-Flexuraltorsional Coupling
Authors: Arshad Mohammad
Published: May 2021

The characteristic (or frequency) equation of a flexible manipulator with a rigid tip mass is derived. The manipulator is modelled as an Euler-Bemoulli beam and it permits flexural (bending) deformation in two planes and torsional deformation. The position of the centroid of the tip mass may not necessarily be coincident with the elastic axis of the beam. This is represented by the use of offset coordinates. The natural frequencies of the manipulator are obtained by solving the characteristic equation. The results are compared to the results in the literature, where possible, and also to those obtained using a commercial finite element software ANSYS. The effects of the magnitude of the tip load, offset of the tip mass centre of gravity from its point of attachment, the length of the beam and slenderness ratio on the natural frequencies are examined.
An air dispersion model for the city of Toronto, Ontario, Canada
Authors: Sylvestre-Williams Barbara
Published: May 2021

Air quality is a major concern for the public; therefore, the reliability of models in predicting the air quality accurately is of a major interest. The objective of this study was to develop an air dispersion model and demonstrate that it can be successfully used in place of or in conjunction with ambient air monitoring stations in determining the local Air Quality Index (AQI). This thesis begins with a review of existing atmospheric dispersion models, specifically, the Gaussian Plume models and their capabilities to handle the atmospheric chemistry of nitrogen oxides (NOx) and sulphur dioxides (SO₂). It also includes a review of wet deposition in the form of in-cloud, below-cloud, and snow scavenging. Existing dispersion models are investigated to assess their capability of representing atmospheric chemistry, specifically in the context of NOx and SO₂x substances and their applications to urban areas. A review was completed of previous studies where Gaussian dispersion models were applied to major cities around the world such as London, Helsinki, Kanto, and Prague, to predict ground level concentrations NOx and SO₂. For the purpose of this thesis, Gaussian air dispersion model was developed, known as the Air dispersion model for the Road Sources in Urban areas (ARSUS) model, which is capable of predicting ground level concentrations for a contaminant of interest. The ARSUS model was validated against the US EPA ISC3 model before it was used to conduct the two studies in this investigation. These two studies simulated weekday morning rush hour tailpipe emissions of CO and predicted ground level concentrations. The first study used the ARSUS model ARSUS model to predict ground level concentrations of CO from the tailpipe emissions of CO for roads and highways located in the vicinity of the Toronto West ambient air monitoring station. The second study involved an expansion of the domain to predict ground level concentrations of CO from tailpipe emissions from highways located in the City of Toronto. The modelled concentrations were then compared to the Toronto West ambient air monitoring station. ARSUS model’s results indicate that air quality in the immediate vicinity of roads or highways is highly impacted by the tailpipe emissions. Higher concentrations are observed for the areas adjacent to the road and highway sources. The tailpipe emissions of CO from highways have a higher contribution to the local air quality. The predicted ground level concentration from the ARSUS model do under-predict when compared to the observed data from the monitoring station; however, despite this a predictive model is viable.
Measurement of viscoelastic properties of treated and untreated cancer cells using passive microrheology
Authors: Bekah Devesh
Published: May 2021

Experiments have shown that there is an increase in ultrasound backscatter from cells during cell death. Since cell scattering depends on the mechanical property variations, one step towards a better understanding of the phenomenon involves measuring the cells' viscoelastic properties. Two promising techniques used for such studies are particle tracking microrheology (1P) and two-point microrheology (2P). The main aim of this work is to develop and test the ability of both to measure changes in viscous and elastic moduli of breast cancer cells during chemotherapeutic treatments. First, the viscosities of glycerol-water mixtures measured using microrheology were found to be within 5% of rheometer values. The viscous and elastic moduli of 4% and 6% poly(ethylene oxide) solutions were successfully measured at 30°C and 37°C. For MCF-7 cells, a 10-fold increase in the elastic modulus was observed using 1P, without a corresponding increase in the viscous modulus. Thus, it was shown that MCF-7 cells undergo an increase in stiffness during apoptosis.
Negotiating cultural transmission : Asian Indian immigrant parents and children
Authors: Pundir Chanda
Published: May 2021

The study examines parenting experiences of Asian Indian immigrant parents and their second generation adult children to understand how immigrant families negotiate differences and similarities between cultural values and beliefs within the family and dominant society at large. Participants in the study included seven first generation couples and their adult children who were born and brought up in Canada. Both parents and one child per family were interviewed separately using open ended in-depth interviews. The analysis of the interviews resulted in certain core themes: (1)Contextual factors; (2)Notions of family; and (3)Parenting as a process. The parenting experience of immigrant parents and children embedded within a socio-cultural context where cultural maintenance and cultural adaptation both serve as an important role in the adaptation and adjustment of these families. The study highlights the need for a cultural and developmental perspective to understand experiences in the context of immigration.
Reading, seeing and hearing voices: What can autistic people teach social work?
Authors: McEvenue Tobi
Published: May 2021

Social workers are prominent in the lives of autistic individuals in their capacity as intake workers, group facilitators, and counsellors. There are few examples of literature written by social workers regarding working with autistic individuals and groups, and even fewer studies which surface the voices of autistic individuals. Preliminary Grounded Theory research was conducted using asynchronous online interviews with three adult autistic participants to explain how they experienced the process of social work interventions in their lives. The emergent themes from this study include “I wouldn’t want a cure”, neurotypical assumptions of ability and disability, fluid and intersecting identities, help-seeking and autonomy, cautionary self-advocacy, neoliberal service provision and creating ineligibility, multiple categorizations and “body control”, “I don’t even really know what a social worker is supposed to do”, and critical social work facilitation. This preliminary grounded theory research may form the basis of a future larger, grounded theory study.
A Holistic Approach to and Automation of Wide Area Protection Coordination
Authors: Alaeddini Saman
Published: May 2021

The electric power transmission network of today is undergoing significant changes in terms of the operational requirements, connected distributed energy resources technologies, and regulatory requirements. In conjunction with an aging infrastructure, these changes have presented new challenges to utilities in their fundamental mission of providing reliable electrical power to the customers. Thus, protection systems must overcome additional challenges towards safe and reliable operation of the power system. Increased investigation of protection system performance is therefore needed to ensure proper coordination of protective relays. However, the complex and integrated nature of the modern protection and control systems call for more sophisticated modeling and study tools for the simulation and analysis of both the dynamics of the interconnected transmission systems and interactions among numerous sets of intelligent electronic devices. Although the protection technology designed for transmission systems is mature, coordination of devices is still a major challenge. This thesis presents a holistic approach to conducting wide-area protection coordination studies through the use of a practical automation-assisted methodology. The wide area protection coordination solution covers process and data management considerations. It also provides a framework workflow for the execution and review of coordination studies, as well as processing and documentation of results to support reliability improvements. The fundamental concept behind the proposed approach is the utilization of software-based automation in a number of key tasks. Firstly, the execution of large-scale protection system coordination studies can be largely automated through utilization of specialized scripts running within short circuit simulation software packages. Secondly, the vast amounts of data inherent in the protection system coordination study results are processed in a manner that assists protection engineers in the identification and resolution of coordination issues. Finally, user friendly automated study summaries are generated that can be used as a record of protection setting recommendations. The effectiveness of the proposed solution is demonstrated through simulations conducted in the CAPE software environment for short circuit studies.

The case for including additional long‐term oriented environmental data in coffee and cocoa futures forecasting models: an exploration
Authors: Daitchman Jaclyn
Published: May 2021

Price discovery is a key function of the futures markets yet limited public information exists about the price‐building models used by market participants. To fill a gap in the literature, interviews were conducted with the largest coffee and cocoa traders, investors, and organizations to provide insight into the models they use to forecast supply and futures prices, with an emphasis on the environmental factors considered to have a significant impact on yield. Despite concerns in the academic literature about soil degradation and climate change affecting the future viability of these crops, market participants primarily based their forecasts on short‐term weather patterns that deviated from the norm, as per historical data. Participants’ near‐unanimous acknowledgement that low coffee and cocoa prices pose a threat to the sustainability of the industry suggests that there is room to price in long‐term factors into short‐term futures models.
Inclusion in the Classroom : Examining Feelings of Inclusion of Newcomer and Aboriginal Students in Ontario's Public School System
Authors: Lobel Rachel
Published: May 2021

Although schools have the potential to be inclusive spaces for children and youth from all backgrounds, the current study has found that in Ontario, newcomer and Aboriginal students’ perceptions of inclusion differ from those of their non-newcomer and non-Aboriginal counterparts. Through the analysis of a survey conducted in 2009 students enrolled in public, private or Catholic schools from grade 6 through 12, this essay compares the feelings of inclusion of newcomer and Aboriginal students in Ontario to those not falling within these two categories. Further, it determines whether or not the feelings of inclusion exhibited by the respondents in Ontario were similar to or different from those of their counterparts in the rest of the provinces. Interestingly, though newcomers in Ontario were actually found to feel more included in their schools than their non-newcomer counterparts, this was not the case in the rest of Canada, but, while Aboriginal students felt less included than their non-Aboriginal counterparts in all provinces, in Ontario the gap between the two groups was wider. This essay examines these findings and makes suggestions for improving inclusivity in Ontario’s school system. Key words: social inclusion; social exclusion; schools; newcomer children and youth; Aboriginal children and youth; colonialism.

Determining Operation Groundswell’s Future Business Directions for Sustainable Tourism
Authors: Charendoff Halina
Published: May 2021

Operation Groundswell (OG) is a non-governmental organization (NGO) and tour operator that offers volunteer backpacking trips. This study evaluates two ways in which OG aims to achieve sustainable tourism: their approach to voluntourism and their carbon offset initiative. A qualitative consumer analysis was conducted to evaluate how OG can move forward as a facilitator of sustainable tourism utilizing 1) their approach to voluntourism and 2) their carbon offset initiative. Findings from this study reveal that OG’s carbon offset initiative should be made more prevalent and transparent on their website and in their marketing to attract green consumers, that they should continue to engage with voluntourism with a critical lens so as to emphasize how voluntourism can be accomplished in an ethically-just and sustainable manner, and that they should consider developing hybrid trip offerings that emphasize the interconnectedness of their four program themes of health, education, human rights and the environment.
Hybridity and integration: a look at the second-generation of the Sri Lankan Tamil diaspora in Toronto
Authors: Atputharajah Akalya
Published: May 2021

This study illustrates that many second-generation members of the Sri Lankan Tamil diaspora in Toronto display an identity of hybridity. This is evidenced by their self-identification practices as well as their conscientiousness in navigating around dominant cultural values and the Canadian society's general lack of knowledge about their ethnic origin. It further shows that these diasporic members believe that successful navigation may result in greater equality and subsequent integration in the realms of economy and politics. The results of this study confirm that hybridization instead brings about deception that the second-generation has the tools to re-negotiate power, when it is not the case - rather cultural ambivalence and ascription prevent the diaspora from challenging dominant cultures. In fact, the discourse on hybridity and its potential benefits may itself be a tool for the dominant group to reinforce oppressive power structures and uphold the barriers to true integration and equality.

Keywords: diaspora, identity, hybridity, second-generation, Sri Lankan Tamils, Toronto, integration
Pricing spread options under Levy jump-diffusion models
Authors: Cane Matthew
Published: May 2021

This thesis examines the problem of pricing spread options under market models with jumps driven by a Compound Poisson Process and stochastic volatility in the form of a CIR process. Extending the work of Dempster and Hong, and Bates, we derive the characteristic function for two market models featuring normally distributed jumps, stochastic volatility, and two different dependence structures. Applying the method of Hurd and Zhou we use the Fast Fourier Transform to compute accurate spread option prices across a variety of strikes and initial price vectors at a very low computational cost when compared to Monte-Carlo pricing methods. We also examine the sensitivities to the model parameters and find strong dependence on the selection of the jump and stochastic volatility parameters.
The shifting conception, construction and consumption of celebrity
Authors: Rosenberg Rebecca Malka Adam
Published: May 2021

How have relatively new technologies changed the way in which the celebrity system and tabloid culture function in North American culture? With access to technologies, such as the internet and digital film and photography, and websites, such as Youtube.com, the average citizen is now able to actively participate in the world of celebrity and even turn themself into a celebrity figure. The world of celebrity (online, at least) has become do-it-yourself and has, in many ways, democratized the process of fame. Through the rise in online readership and recognition, even the creators of online tabloids have themselves become celebrities and active members in the star system they seek to critique. This thesis will demonstrate that the technologies used to demystify the celebrity through perpetual surveillance have, at the same time, succeeded in turning ordinary people into celebrities, thus placing them squarely within the star system they never intended to inhabit.
Synthesis and Application of Chiral Palladium-Phosphane Precatalyst in Enantioselective C-N Cross-Coupling
Authors: Wright Nande Abena
Published: May 2021

The various strategies and reaction conditions towards the synthesis of benzene-, naphthalene-, and phenanthrene-based dicyclohexylbiaryl phosphanes are presented. A chiral third generation Buchwald-type precatalyst has been synthesized, employing the non-commercially available ligand, (R)-dicyclohexyl(2'-methoxy-[1,1'-binaphth-2-yl])phosphane, (R)-Cy2MOP, and a dimeric methanesulfonate-bridged palladacycle based on a 2-aminobiphenyl scaffold. Application of the palladacyclic precatalyst in an enantioselective variant of the BuchwaldHartwig reaction is demonstrated in the desymmetrization of prochiral α-(2-bromobenzyl)malonamides via intramolecular N-arylation. The scope of the catalysis in the presence of the precatalyst has been investigated with efforts towards optimizing yields, catalyst loading, and enantioselectivities. Attempts towards the isolation of a potential reaction intermediate in the form of a stable amido-bound palladium complex are discussed. Finally, strategies towards gaining mechanistic insight on the origin of the enantiomeric excess are discussed.
Design and Analysis of a Dynamic Loading System for a Morphing Winglet
Authors: Buchkazanian Raffi
Published: May 2021

The following thesis paper investigates the possible methods to perform a dynamic load test on a morphing winglet. A morphing winglet design capable of deflecting in the cant direction was developed by a joint partnership between Ryerson University and Bombardier Aerospace. In order to validate the model and complete a proof of concept, a loading fixture was required to test the structural integrity of the winglet under a defined load. Upon completion of an enumeration study of planar four-bar linkages, a passive R-P-R-P mechanism was designed to apply a constant perpendicular load throughout the cant motion. A design of the half size loading fixture was developed, optimized and manufactured to integrate with an existing cant module. The dynamic loading model was validated by producing a positive correlation between the theoretical analysis and the experimental results, leading to a successful proof of concept for a full scale test.
Analysis of Gas-Liquid Flow in an Aerated Reactor Equipped with a Coaxial Mixer through Tomography and CFD
Authors: Hashemi Nasim
Published: May 2021

This doctoral thesis addresses the mixing of highly viscous Newtonian fluids (corn syrup solutions) in a novel aerated reactor equipped with a central impeller (a pitched blade turbine in upward or downward pumping mode) and a wall scraping anchor. The non-intrusive electrical resistance tomography (ERT), dynamic gas disengagement method (DGD), design of experiments (DOE), computational fluid dynamics (CFD), and population balance model (PBM) were employed to characterize the performance of this novel aerated system. The performance criteria to be examined were mixing time, power uptake, gas holdup, and bubble size distribution.

In this study, novel correlations were developed to estimate the gassed power drawn by the coaxial mixer, mixing time, and gas holdup. In addition, to obtain a master power curve, two new dimensionless correlations were proposed for the generalized power number and gas flow number by incorporating the equivalent rotational speed for the coaxial mixer, speed ratio (central impeller speed/anchor speed), and the central impeller power fraction into these two correlations. The experimental data demonstrated that gas flow affected the aerated anchor power consumption and central impeller power consumption in different manners. It was also found that at the higher fluid viscosity and beyond the critical speed ratio of 10, the anchor power consumption was increased by increasing the speed ratio (i.e. decreasing the anchor speed). It was shown that in the presence of gas, the anchor impeller in combination with the upward pumping pitched blade turbine in the co-rotating mode exhibited shorter mixing times and lower power consumption than the anchor-downward pumping pitched blade coaxial mixer.

To enhance the efficiency of the aerated mixer, it is critical to investigate the influence of the gas-liquid flow within the vessel on the bubble size distribution (BSD) and the local and global gas holdup. To achieve this goal, the effects of the bubble breakup and coalescence on the BSD within the vessel were incorporated into the CFD model through the CFD-PBM coupling. The experimental and simulation results showed that beyond the critical speed ratio of 10, the volume fractions of the large bubbles decreased while the volume fractions of the small bubbles increased.
Evaluation and modeling of human posture and balance in response to sensory inputs in a virtual environment
Authors: Virk Sumandeep
Published: May 2021

Balance control, spatial orientation and upright posture require an accurate integration of sensory inputs. In order to understand the integration in terms of motor learning and balance improvement, experiments were conducted in a virtual environment.
The objectives of the current work were to: 1) examine the postural muscle responses, head movements, and game performance in young healthy subjects when they were exposed to unpredictable situations in the virtual environment 2) examine the extent of learning transfer that occurred in the virtual environment to the real world by means of pre and post posture tests 3) propose and validate the theoretical model that simulates experimental results.
Results revealed that game performance increased during training in the virtual environment. The postural test results, electromyogram and head movement data have implications in using the virtual environment in balance and vestibular rehabilitation, for alleviating simulator sickness symptoms, and enhancing spatial knowledge and memory. The model simulates the experimental results very closely and sheds light on the activation of muscles under specific situations encountred in the environment. Overall, the experimental results supported our hypothesis.
Cubesat BDOT Control Modelling-Detumbling and Angular Momentum Management
Authors: Obodozie Veronica Chigoziri
Published: May 2021

The purpose of this thesis is to explore the uses of magnetic torquers on a CubeSat. This is focused on tuning the gain value of a B-DOT controller for the Detumbling of the ESSENCE CubeSat. This was tested with a converged rate value of 0.05deg/secs as the criterion over 15 orbits; with each simulation having a total of 20 runs. The matrix chosen for the gain value was tested to ensure it was feasible regardless of a change in the initial tumbling rate, settling time and slight command errors. The Appendix shows sample test results for this model. The second magnetic torquer use which was to have a gain tuning was the momentum dumping. the control law was a variant of the B-DOT controller focusing on the angular momentum, this was applied to the form of Angular Momentum Management of the CubeSat. Although the overall testing procedure was edited, more tuning is required for the momentum dumping gain value.
Uberization of rooftops for vegetation
Authors: Shirvan Mahsa Hatefi
Published: May 2021

Agricultural rooftop systems can be productive during the growing season which starts from mid-spring and lasts until mid-fall. The absence of snow load in summer time presents an opportunity to receive and accommodate the extra load from agricultural assemblies in order to turn the underutilized summer rooftops into productive organic food resource for the community.

For this purpose, roof morphology of 31 supermarkets in Mississauga has been reviewed through case study method along with exploration of urban-condition growing methods and requirements from recent literature and case studies. The results indicate the possibility of seasonal growing through extensive, intensive planter-based and hydroponic systems as well as hanging planters with trellises structure.

A methodology using UML & SADT to develop an effective business model in healthcare
Authors: El-Ashy Akram Kamal
Published: May 2021

A business process model is an abstraction of business funcionality in terms of modeling the goals, processes, objects and any other associated events of an enterprise. An effective business model can show how an enterprise and its subsets function today, and how one may plan for it to function in the future. Effective business modeling to gain insights towards improvements in hospital areas has been used infrequently by industrial engineers. This thesis presents a methodology using UML (Unified Modeling language) and SADT (Structured Analysis & Design Technique) that may be utilized to develop an effective business process model in the medical imaging area of a major Canadian hospital (St. Michael's Hospital). The effectiveness of this business model may clear the way towards a comprehensive analysis for improvements.
Improved Low Voltage Ride Through Capability of Wind Farm using STATCOM
Authors: Montazeri Miad Mohaghegh
Published: May 2021

Using power electronic converters with reduced capacity in doubly-fed induction generator (DFIG) based wind turbines make them vulnerable to over-current during grid disturbances. This thesis aims to analyze the behaviour of doubly-fed induction generators based wind farm for various timing schemes of crowbar deactivation and resumption of rotor side converter (RSC) in the case of grid fault. Also, usage of a static synchronous compensator (STATCOM) for the purpose of stabilizing the grid voltage after a three-phase fault is studied in this these. Moreover, finding minimum capacity of STATCOM which ensures low-voltage ride through (LVRT) of wind farm is studied. Finally, coordination of reactive power from wind turbine generators and STATCOM in steady-state condition is performed. All the results in this thesis show that STATCOM improves low voltage ride through (LVRT) capability of wind farm and assists for an uninterrupted operation of wind turbine generators during grid faults.
The role of metamemory in autobiographical memory performance in dysphoric individuals
Authors: King Matthew James
Published: May 2021

Autobiographical memory (AM) performance in individuals with depressive symptoms has repeatedly been shown to be overgeneral (OGM) in nature, and characterized by summaries of repeated events or long periods of time rather than a single event tied to a unique spatial and temporal context. The present body of work was designed to address the metamnemonic aspects of AM performance in dysphoric individuals, with the underlying motivation being that OGM may not be a unique phenomenon specific to depression or AM, and that it may reflect a more general pattern of memory impairment. The studies presented herein examine various aspects of metamemory and other memory processes that may offer a parsimonious account of OGM as poor event memory in general, rather than a specific standalone finding. In Study 1 several metamnemonic processes were investigated using a quantity-accuracy profile approach. Here, the results showed that performance between dysphoric and non-dysphoric participants was nearly indistinguishable on measures of calibration, resolution, grain-size setting, and criterion setting, suggesting that these aspects of metamemory are intact in dysphoria for immediately tested material. Study 2 examined whether it is possible to “create” OGMs by employing a delay manipulation for both autobiographical (3 day delay) and laboratory-based events (7 day delay). Indeed, the results from this study showed that the performance on both tasks declines for both groups, but that this effect was of a greater magnitude in the dysphoric group. Critically, no differences emerged for immediately tested information. Finally, Study 3 examined the role of working memory and memory search strategies in the recollection of autobiographically relevant information. The results from Study 3 showed that dysphoric individuals may engage in a less organized search strategy than non-dysphoric participants as exhibited by a tendency to switch set in the midst of thematically related information. Taken as a whole, these data indicate that OGM may be attributable to deficits in memory search strategies in conjunction with memories that may be more prone to decay and/or forgetting, suggesting that OGM may not be a depression-specific phenomenon, but rather the downstream deficit of degraded memory representation.
Model selection in stock correlation networks
Authors: Alipourjeddi Narges
Published: May 2021

In this research we construct market networks to study correlation between the price return for all Dow Jones, NASDAQ-100 and S&P 100 indices that were traded over a period of time. We consider market networks, which have stocks as nodes and edges corresponding to correlated stocks. Specifically, a winner-take-all approach is used to determine if two nodes are adjacent. We identify that all networks based on the connecting stocks of highly correlated price returns display a scale-free degree distribution.
Additionally, we use features for representing different aspects of the network. The feature includes small connected sub-graphs with three and four vertices. We use an algorithm to count frequently the number of the graphlets for our mathematical models and our constructed networks. Each network is assigned an 8-dimensional vector.
We present a model selection algorithm based on supervised learning. Our algorithm classifies our market networks with the best fitting mathematical model.
The Extremist Islamist Presence in Canadian Webspace : an Empirical Study
Authors: Thomson Neil
Published: May 2021

This paper outlines the results of a two month study in which a series of extremist Islamist websites - registered, hosted or given datacentre services by Canadian internet companies- were empirically observed. The results of this project are inserted into a framework which explores the misuse and wrongful application of the "terrorist" signifier to substate or nonstate activities, discerns between the purported use of the internet by extremist Islamist organizations for destructive means and the real use of the internet by such groups, and suggests a number of conclusions based on prior administrative responses to the extremist Islamist use of the internet.

Pump up the jam: how music in brand advertising can create deeper connections with consumers
Authors: Andrejicka Laura
Published: May 2021

As our visual landscape becomes saturated with advertisements and media technologies, the advertising industry is using sound in more ways than ever before to open new acoustic channels between brands and consumers. Through analysis of scholarly literature, advertising industry publications, and three recent advertising campaigns and online commentary around those campaigns, this MRP highlights the way advertisers attempt to use sound and music as a “universal language,” as a way of accessing emotion, and as a technique for engineering responses in audiences. The scholarly literature review identifies two broad approaches to research on music in advertising: the first focuses on harnessing the power of sound to enhance the impact of advertising messages whereas the second approach contextualizes and critiques the use of sound in advertising. Informed by concepts and themes in the scholarly literature, the MRP then turns to an analysis of the use of sound in three specific advertising campaigns: Oreo’ s 2013 “Wonderfilled,” Nike’s 2016 “Unlimited Together,” and Adidas’ 2017 “Original Is Never Finished.” Finally, the MRP identifies dominant perspectives of sound and music among advertising professionals through analysis of fifteen AdAge issues, a popular advertising trade journal, using a coding scheme based on the work of Powers (2010), Scott (1990), and Serazio (2013). Together, these three methods provide an in-depth understanding of the dominant perspectives of sound and music which shape the use of these modalities in the advertising industry.
Wood 3.0
Authors: Tisler Filip
Published: May 2021

The flawlessness of today’s standardized construction methods has created and reinforced a weakened and artificial understanding of materiality. By furthering our comprehension of natural materials, particularly wood,
designers are able to grasp the significance of the materials they employ, understand and manipulate in terms of its characteristics and boundaries. Wood as an organic living organism can be used to express a particular narrative, to tell a story of its existence and history within human use, as well as its individual identity, age, and testimony. This thesis attempts to address the potential digital fabrication methods that can be utilized to manipulate wood and its properties, which ultimately has profound implications on the tactile and sensory experiences of space. In order
to create a haptic presence, the elaborate surface, textures, and details of wood are crafted for the user, and invite all the senses by creating an atmosphere in the space.
Module-based kinetostatic analysis and optimization of a modular reconfigurable robot
Authors: Mohamed Richard P.
Published: May 2021

n this thesis, a newly developed kinetostatic model for modular reconfigurable robots (MRRs) is presented. First, a kinetmatic computational method was created to allow for simple connectivity between modules which included the possibilities of angular offsets. Then, a flexibility analysis was performed to determine the static and dynamic flexibility of link and join modules and the regions of flexibility were plotted to determine exactly which of the components can be considered flexible or rigid, depending on their sizes. Afterwards, the kinetostatic model was developed and compared to a finite element model and results give essentially the same tip deflections between the two models. This kinetostatic model was then used to determine the maximum allowable payload and maximum deflection position for a given MRR. Additionally, a direct method was created to determine the cross section properties of all modules in a given MRR for a given payload and maximum desirable tip deflection.
