Fundamentals of mega hertz femtosecond laser ablation and its application in interconnection via drilling
Authors: Panchatsharam Senthilnathan 
Published: May 2021

<p>With the ever increasing demands on electronics and its portability, speed and function, the need for lighter and faster processing chips is always there. 3D stacking of chips is enabled through Inter-chip connections or Interconnect vias, which is used to create the electrical connections that facilitate the stacking. Interconnect vias provide the connectivity between the layers of the physical design, resulting in short connection lengths, which improve performance and decrease power consumption significantly. This thesis proposes a high repetition rate, high power femtosecond laser drilling technique for surpassing the quality and throughput demand posed by the current market. A systematic study of the influence of the laser control parameters such as the repetition rate, pulse energy, intensity, wavelength, pulse duration, ablation threshold, quality and throughput rates is analyzed in detail. Decreasing via diameter and increasing via depth at high repetition rate are noted. A smallest via of 8.39 µm and a deepest via of 121 µm were obtained at 13 MHz and 4.33 MHz respectively. Minimal debris accumulation and exceptional surface qualities were noted at high repetition rates. Theoretical and experimental studies of shockwave effects during laser ablation on via surfaces were analyzed. Systematic process of learning the propagation of shockwaves and generating raised rims in ablated crater is analyzed. Analyzing surface temperature of the target revealed presence of small molten liquid layer at 13 MHz. Newly termed observations, primary and secondary rims, were observed and analyzed under the influence of various laser parameters. Rim line width spacings were seen increasing at higher pulse ;vidth and higher power density. Gas assisted ablation showed decreasing line width spacing due to forced convection. Hence, with the successful results from the studies, the laser system shows the capability of meeting and surpassing the current market demands and considered for commercial applications. </p>
The United States Farm Security Administration-Office of War Information Archive: A Latent Nexus of Truth About the New Deal Era
Authors: Berenyi Monika E. 
Published: May 2021

<p>Since the conclusion of World War II, the ethos of the Roosevelt administration (1933-1945) and the achievements of the New Deal era have been celebrated by official rhetoric. American Document is a dynamic storytelling platform which deconstructs the validity of this long-sustained authority in the United States. Between 1935 and 1944, the United States Resettlement Administration (1935-1937), Farm Security Administration (1937-1942), and Office of War Information (1942-1944) contributed to the capture of a panoramic portrait of America in the form of a photographic survey. Collectively, these photographs constitute the Farm Security Administration-Office of War Information archive, and impart an unparalleled documentary account of the New Deal era. This Thesis engages archival evidence to question and illuminate how state socialism was imposed on an unsuspecting people at the expense of individual liberty, free enterprise, and the ebb and flow of the American dream. </p>
OSPF for Wireless Mesh Backbone Network
Authors: Alwan Ali Mohsen 
Published: May 2021

<p>Wireless mesh network (WMN) is popular for providing decentralized and relatively inexpensive Internet access, especially in Community network and geographically challenged areas of deployment. In this thesis, we proposed using OSPF as the underlying routing protocol in the Wireless Mesh Backbone (WMB) network. We investigated the convergence and configuration issues of OSPF in WMB network. We evaluated the performance of OSPF and compared with AODV (reactive ad hoc protocol) and OLSR (proactive ad hoc protocol). We proposed using multiple subinterfaces under a single physical wireless interface in configuring multiple subnets to deal with the hidden nodes problem in WMB networks. We also proposed using the BGP protocol to interconnect multiple OSPF areas for the sub-urban topology. The performance of this approach in terms of convergence time was studied. </p>
A Security Enhanced AODV Routing Protocol For Wireless Mesh Networks
Authors: Wang Ahuang 
Published: May 2021

<p>This thesis introduces a Security Enhanced AODV routing protocol for wireless mesh networks (WMNs). SEAODV employs Blom's key pre-distribution scheme to compute the pairwise transient key (PTK) through the flooding of enhanced HELLO message and subsequently uses established PTK to distribute the group transient key (GTK). PTK and GTK are used for authenticating unicast and broadcast routing message respectively. In WMNs, a unique PTK is shared by each pair of nodes, while GTK is shared secretly between the node and all its one-hop neighbours. A message authentication code (MAC) is attached as the extension to the original AODV routing message to guarantee the message' s authenticity and integrity in a hop-by-hop fashion. Security analysis and performance evaluation show that SEAODV is more effective in preventing identified routing attacks and outperforms ARAN and SAODV in terms of computation cost and route acquisition latency. </p>

Authors: Pinkus Stefany 
Published: May 2021

<p>The Spanish-speaking community has recently been getting much attention in Canada due to the prevalent low academic achievement of children of Latin American immigrants. The focus of this study is on empowering Latin American parents to become active participants in their children’s education and take control of their children’s’ educational path. This study documents a Spanish-speaking parent group that combined the “empowerment” approach to family literacy, drawing from elements of the Early Authors Program and the creation of a support network, which was named “Parenting Circles”.The study found that theParenting Circles Program is a useful tool inhelping Spanish-speaking parents maintain their home language, and in promoting overallengagement in their children’s academic development. </p>
Developmentally inappropriate practice? : westernized barriers to the parenting value filial piety
Authors: Phyllis Lisa 
Published: May 2021

<p> </p>
<p>A sociocultural study hypothesised Chinese parents in Canada would express values informed by filial piety. The extent to which filial piety characteristics informed parenting values, the extent to which family characteristics related to parenting values and the extent to which families felt their values were reflected in Canadian parenting literature were explored. Questions were asked to highlight the problematic nature of Developmentally Appropriate Practice's universalistic approach to development. Survey research involved 30 participants' questionnaire responses. Results were mixed. Parents expressed an independent orientation regarding goals; whereas, values were consistent with filial piety. Agreement with parenting literature was marginal. Most research is needed to examine whether a hegemonic ideology contributes to Chinese parents goals; Chinese parents reported values informed by filial piety. No previous studies were found specifically investigating Canadian parents of Chinese origin. Potential benefits include identifying barriers to partnership and opportunities to develop awareness of global parenting goals.</p>
Arm movements and dynamic postural stability : accelerometer-based balance tests
Authors: Milosevic Matija 
Published: May 2021

<p>Background: Epidemiological studies show a high incidence of falls and demonstrate that they cause serious consequences to individual health and quality of life, as well as significant social and healthcare impacts. The literature shows that poor balance is a major cause of falls, and emphasizes the need for valid and effective balance diagnostics and risk assessment of falls and balance impairments. The literature review also indicates that arm movements have a potentially significant effect on balance. </p>
<p>Conclusions: This study shows that the proposed accelerometer-based tests provide useful diagnostic information for postural balance and arm movements evaluation. These devices provide valuable diagnostics information, data for progress monitoring during balance training, and consequently enhance risk assessment and falls prevention. Finally, the study shows the important impact of arm movements on dynamic balance and provides an insight into dynamics of the arm movements and balance maintenance.</p>
Study of estimation of distribution algorithms applied to neuroevolution
Authors: Holker Graham 
Published: May 2021

<p>This thesis proposes a methodology for the automatic design of neural networks via Estimation ofDistribution Algorithms (EDA). The method evolves both topology and weights. To do so, topol-ogy is represented with a fixed-length, indirect encoding; weights are represented as a bitwise en-coding. The topology and weights are searched via an incremental learning algorithm and a GuidedMutation operator. To explore suitable EDA ensembles, the study presented here interchangeablycombined two representations for topology, two for weights, and two learning algorithms. Testsused in the analysis include: XOR, 6-bit Multiplexer, Pole-Balancing, and the Retina Problem. Theresults demonstrate that: (1) the Guided Mutation operator accelerates optimization on problemswith a fixed fitness function; (2) the EDA approach introduced here is competitive with similarGP methods and is a viable method for Neuroevolution; (3) our methodology scales well to harderproblems and automatically discovers modularity. </p>
A secure multiparty micropayment protocol for internet access over WLAN mesh networks
Authors: Biswas Nitish 
Published: May 2021

<p>Presently, multi-hop WLAN mesh networks have become an alternative to wired networks for last-mile user access enabling numerous internet-based services. Thus, we have proposed MMPay, a secure multiparty micropayment protocol for internet access over WLAN mesh networks, enabling: a secure network access anywhere and anytime according to user desire; seamless user roaming across the independent operator’s networks; and lightweight real-time payments to all involved parties that eliminate huge user trust relationships, online remote user authentications and mutual roaming agreements among the participating parties. The incontestable MMPay scheme has been devised from existing micropayment schemes emulating their good attributes and eliminating security vulnerabilities and difficulties, which includes: hash-chain based variable length payment instrument, user’s payment certificate at smartcard, shared and mixed signature scheme, and an efficient redemption approach. The OPNET-simulation results show that the pricing contract response-times are little lengthy but have no effect on data communication; payments and hand-offs are efficient; and the scheme has no effect on data communication ETE-delay and throughput. Thus, the scheme is secure, efficient and lightweight, and will be a practical solution for future small to large-scale WLAN mesh networks enabling faster hand-off. </p>

Virtual Human Factors Tools for Proactive Ergonomics: Qualitative Exploration And Method Development
Authors: Perez Jorge 
Published: May 2021

<p>This thesis presents two studies that explore the use of Virtual Human Factors Tools (VHFT), such as Predetermined Motion Time Systems (PMTS), Digital Human Models (DHM) and Discrete Event Simulation (DES). Study 1 investigated the needs and expectations of ergonomist and engineers through a series of explorative workshops. Nine characteristics of concern to participants were identified in the tools: time, cost, training, difficulty to use, trustworthiness, graphics, flexibility, usefulness and report presentation. These characteristics can influence VHFT uptake and application decisions. Study 2 explored the integration of DES, PMTS, DHM and existing fatigue models, in an assembly context, to predict the accumulation of muscular fatigue. This study demonstrated the feasibility of using VHFT in conjunction and that DES can predict ergonomic outcomes such as work-related fatigue and recovery. The study also uncovered some problems with the existing fatigue models, highlighting the need for further research and development of those models.</p>
A Developmental Study of 9- And 12-Month-Old Infants' Learning From Televised Video
Authors: Labine Danielle 
Published: May 2021

<p>Although infants are exposed to relatively high levels of television the impact of this exposure on learning is not completely known. Research has shown that infants learn significantly less from a televised demonstration than they learn from a live demonstration. It was hypothesized that providing 9‐ and 12‐month‐old infants with active experience with the task objects after a demonstration would increase learning from television. Overall, infants were able to solve means‐end tasks quite well and transfer the modeled solution across several test trials with slightly different tasks. Surprisingly, the results showed that infants learned equally well from the live and video demonstrations and did not show a video deficit effect. In addition, no age differences were found. However, as expected, infants performed much better in the active training conditions compared to the passive conditions. Findings are discussed in terms of the perceptual impoverishment theory and the dual representation theory.</p>
A fatigue damage model developed based on stiffness degradation in human Haversian cortical bone
Authors: Najmi Hossein 
Published: May 2021

<p>The present study intends to develop a fatigue damage model to assess the fatigue response of human cortical bone by incorporating stifffness degradation of bone materials as the number of loading cycle progresses. The proposed fatigue damage model is defined based on mechanical properties and biological parameters of human cortical bone subjected to repeated loads. Stiffness loss in bone and bone constituents was used as a damage index to model the response of fatigue damage. The proposed damage model in this thesis considered bone as a natural composite material consisting of Haversian osteons (fibres) embedded in interstitial bone (matrix) and separated by weak cement-line interfaces.</p>
<p>Predicted fatigue damage results were found in good agreement with many experimentally obtained damage results of human cortical bone. The proposed damage equation also showed a higher degree of success in damage assessment of cortical bone samples tested by different laboratories as compared to other earlier developed damage models. </p>
<p>The proposed damage model, for the first time, successfully correlated the mechanical and histological properies of human cortical bone with damage accumulation of bone constituents. These parameters represent mechanical and histological properties of cortical bone specimens such as osteon volume fraction, donor age, cyclic stress magnitude, secant modulus of osteons, cement line interfacial strength and other bone constituent mechanical properties.</p>
<p>A computer program was also developed to assess fatigue damage of cortical bone by the proposed damage model and evaluate the proposed model with experimental data extracted from the literature.</p>
Cultural Appropriation: Erasure of Cultural Odour, Homolingualization, and Queer Erasure within English Adaptations of Japanese Anime
Authors: Matheson-Mowers Olivia 
Published: May 2021

<p>[Introduction]: </p>
<p>The first month of Pokemon Go is the only time this world knew peace @cake_hoarder (Twitter, September 2019)</p>
<p>The above tweet illuminates the nostalgia and fondness that is often evoked by the memory of summer 2016, a summer that was characterized by the release of Pokemon Go, a smartphone app based on the anime series, Pokemon. The twitter user likens this period to “world peace”, a comparison that is rooted within the design of the game that motivated social interaction among its users. One of the ways that Pokemon Go promoted communal gameplay was through the inclusion of PokeStops, a digitized meeting hub that allows for players to collect Poke Balls. These digital hubs mirrored the ones featured within Pokemon, and similarly to the characters within the anime, players would often encounter other players while visiting Poke Stops. This allowed for players to interact with one another, leading many to exchange tips on where to find rare and hard to catch Pokemon and even forming teams to widen their scope. The fusion of nostalgia for the times of trading Pokemon cards in schoolyards, the collective goal of players, and the warm weather created a rose tint around the summer, one that almost felt like “world peace”."</p>
Pressure curves for compressible flow with slip through constricted cylinders
Authors: Rabba Salahaldeen 
Published: May 2021

<p>The goal of this research is to determine more accurate pressure curves for compressible flow with slipthrough cylinders that have a local constriction. Existing analyses for compressible flow with slip througha local constriction linearize the pressure gradient equation, and higher-order derivatives are dropped as well. The equation to be developed as part of this research retains quadratic pressure gradient terms. The corresponding solution for the pressure gradient is found following existing analysis in the literature for incompressible, no-slip flow, and subsequently the pressure is found using numerical integration. Results are compared to those from the linearized pressure gradient equation to see the extent of the improvement. Results are also assessed and compared to pressure and density curves available in the literature for some specific constrictions. Improvements may be obtained when the second-order derivatives are kept as well inthe pressure gradient equations, which can be assessed and analyzed in the same context. Pressure curves are assessed in different idealized flow geometries including the Gaussian model, a cosinu-soidal model, and a smooth piece-wise polynomial model. In each case the pressure is found, and hence alsothe density. A range of Reynolds numbers, degrees of constriction, length of the constriction, compressibilityand slip are considered. Density curves are separately compared to existing particle-based results obtained from a stochastic particle dynamics using multiparticle collision dynamics. </p>

The Future of masculinity is amphibian: representations of new masculinity in Guillermo del Toro’s The Shape of Water
Authors: Reynoso De La Garza Ana Catalina 
Published: May 2021

<p>[Para 1]: " As evidenced by the October 2019 GQ cover story, “The New Masculinity Issue,” and Harper’s Magazine November 2019 issue, titled “Manhood in the age of #MeToo,” the masculine realm is in the midst of a tumultuous transition. According to Michael Kimmel, scholar on men and masculinities, this situation is by no means new. In his book The History of Men he states, “American men have been searching for their lost manhood since the middle of the nineteenth century” (37). Kimmel believes it was centuries ago that men’s secure sense of manhood was destabilized (37). Top headlines during the 21st century have only further confirmed this is still the case, and that the need for a different kind of manhood is becoming altogether urgent. As the Harper’s Magazine title suggests, the 2017 #MeToo movement indisputably exposed the prevalence and pernicious impact of sexual violence that powerful men are still inflicting on women today. This movement has also demonstrated that a well-adjusted masculinity has not yet materialized. The GQmagazine cover story further suggests that a new masculinity is in order." </p>
Dreams of Paradise
Authors: Asayesh Afsaneh F. 
Published: May 2021

<p>The Persistence of Memory </p>
<p>Memory is what shapes us. Memory drives our aspirations and our search for happiness, for paradise. This project is situated within the architecture of memory, where it explores issues of journey and migration, reminiscence and desire, and the transformation that results when emotions overlay physical xperiences of place. Its structure is the juxtaposition of the journey of paradise with a personal life journey, with memory as the driving force. In explorations and re-formations of paradises, it examines the internalization of place t hrough memory and emotion, and extrapolates the powerful desires thus formed into new expressions of paradise. Paradise - this powerful construct - has endured millennia, manifesting in painting, pottery, tiles, poetry, stained glass, carpets,....and in architecture. As a place, Paradise is about contrast and tension : outside versus inside, lush garden versus arid desert, abundance versus desolation, growth versus stasis. It is about the sanctuary of a garden in contrast to the desert. Transformed into concept, it is about the promise of the ultimate sanctuary of happiness, a sanctuary against death and oblivion. The journey of dissemination and transformation of Paradise is testament to the potency of memory as it propels change, interpreting physical space as we project the dreams of our internal architecture to re-fashion our world.</p>
