Regional heterogeneity in lake morphology in Ontario

Lake size and shape are important factors determining the function and structure of lake ecosystems. Moreover, Lake morphology is important for both biotic and abiotic processes, including species richness of zooplankton, macrophytes, and fishes. In particular, Ontario has tens of thousands of natural ecosystems that make up a large part of Canada’s dominant share ofthe […]

Characterizing Technology Use in Children and Youth with Autism Spectrum Disorder (ASD)

Autism spectrum disorder (ASD) is a neurodevelopmental disorder affecting 1 in 68 children. Approaches that use technology can potentially decrease cost of ASD interventions and treatments and contribute to improving their effectiveness. There is currently not enough evidence to inform how these technology-based interventions should be designed. The goal of this study is to fill […]

The Scale-up Challenge for Canada? Obstacles to High-Growth Technology-based Firms and the Policy Response

Digitally-enabled technology firms will assume greater significance for Canada’s future economic growth and prosperity. The ability to grow digitally-enabled firms from the startup phase to globally competitive scaled up firms will be a critical part of this challenge. Among the advanced industrial economies, Canada ranks second only to the United States in terms of entrepreneurship, […]

Nonlinear Dynamic Analysis of Aero-Engines

Aero-engines are lightweight structures which are assembled of several thin walled cylindrical components (casings). Casings are joined by bolted flanges, and must withstand high forces. To accurately predict the response of casings assembly, the non-linear behavior of the casing joints must be considered. Currently, aero-engine manufacturers (i.e PWC) are facing serious limitations in matching the […]

Validation and calibration of Squeeze Film Damper Model with Experiment

This research project studies a specific component in the commercial aircraft engine called the squeezed film damper, or SFD. The SFD is applied to reduce the vibration of the engine rotor, which in turn reduces the noise and brings comfort to the passengers. The expected delivery from this project includes an advanced SFD model which […]

System Controller – Connector/Harness/Baseplate Redesign Feasibility Study

Electronic assemblies are used to control various systems in an aircraft. Under normal operating conditions, these assemblies undergo vibration, and therefore have an expected life span. Different designs are analyzed to reduce production cost, and these designs have to ensure that the electronic components contained within the hardware can tolerate the same operating conditions without […]

Feasibility Study of Switch Module Redesign

Structural and vibration analysis is performed on a proposed design change on electronic assembly to ensure that it meets customer requirements and is a more cost-effective design. Such design change should be cost efficient. The important aspect, in addition to the design, is interacting with different engineers at different positions in the company. Working with […]

Understanding invasive potential in brown widow spiders

As a result of climate change and human-mediated movement of plants and animals, the establishment of invasive species is increasingly prevalent, with global economic and environmental consequences. Establishment in a new habitat requires successful reproduction in novel environments in the short-term, and successful invasion requires local adaptation in the long-term. Thus, invasive populations may initially […]

One Nation, One Face: A Critical Exploration of Sociality and Cultural Oppression in the South Korean Plastic Surgery Phenomenon

Combining semi-structured interviews of plastic surgery doctors and individuals interested in plastic surgery as well as content analyses of magazine and newspaper articles on plastic surgery, this research aims to inductively examine the intersubjective production of meaning among South Korean individuals in the context of the nation’s massive plastic surgery trend. To this end, this […]
