Buckling Analysis of Hybrid Composite-Metallic Stiffened Structures

In order to reduce the structural weight and operating cost of the aircraft, hybrid structures composed of composite skins and metallic sub-structures are commonly used as components of the wing and fuselage. The skin temperature change of the aircraft during takeoff and landing causes different amounts of deformation in composite and metallic materials due to their difference in thermal expansion properties. This induces internal loads in such hybrid structures, which need to be considered together with the flight loads when evaluating the structure’s stability. This project aims to analyze the buckling behavior of hybrid composite-metallic stiffened structures under combined thermal and mechanical loading conditions. A fast and reliable computational tool will be developed to assist the design of such hybrid stiffened structures in Bombardier. The developed model and analytical methods will also be applied for similar structures on other commercial and business aircrafts in Bombardier.

Advanced Learning for Automatic Object Detection and Tracking in UAV Imagery

Recently there has been a growing adoption of Unmanned Aerial Vehicles (UAVs) in many applications. Robust object detection and tracking algorithms are required in many UAV scenarios. However, existing object detection and tracking approaches are not specifically designed for UAV and therefore do not have satisfactory performance in UAV. In this MITACS cluster project, by working with the industrial partner, we will develop a set of improved object detection and tracking algorithms for UAV. In particular, we will tackle the following sub-topics: 1.) weakly supervised object localization; 2.) visual object tracking and anomaly detection; 3.) partial face detection; and 4.) low-resolution object detection. The algorithms will be integrated into the partner’s products, thereby significantly enhancing their competitiveness in the market, and contributing more to Canadian economy and job market.

Analyses des communautés microbiennes de la sève d’érable par barcoding moléculaire

Des microorganismes se retrouvent dans la sève d’érable au moment de la récolte et ont un lien avec la qualité du sirop, mais on ne comprend pas encore ce qui fait varier les populations de microorganismes d’un endroit à l’autre et en cours de récolte. Le projet de recherche consiste à identifier les microorganismes qui se retrouvent dans la sève d’érable et de chercher les liens avec différentes caractéristiques des érablières et des sirops d’érables pour mieux comprendre ce qui influence leur présence et éventuellement utiliser cette information pour mieux contrôler la qualité des produits de l’érable.

SEA LETTUCE TO BIOCARBON AND BIOGAS WITH RECOVERY OF NUTRIENTS

Human activity in PEI contributes to over 90% of nitrates in island waterways. These nitrates are responsible for the growth of plants and algae including sea lettuce that chokes ponds and waterways, discolor water and create an anoxic event, which is harmful to the marine ecosystem. The proposed research investigates an integrated process for the conversion of sea lettuce into hydrochar and biogas with recycling of nutrients that could justify the harvesting of sea lettuce. The proposed research will create opportunities for the growth of new industries in the area of harvesting, processing and utilization of final products while providing sustainable solution to growing environmental problem. The system can than be applied to other areas having similar problems, thereby creating additional prospects for exporting know-how.

Photons to Fish (PHISH): Ecosystem indicators of fish productivity

Recreational fisheries in Canada are estimated to provide over $2.5 billion dollars to local economies each year. There is a growing concern that industrial activities, climate change, and other factors may negatively impact the productivity of these fisheries and the freshwater ecosystems that support them. However, direct estimates of fish productivity are extremely challenging to undertake, especially in remote locations like Canada’s north. The purpose of this project is to evaluate the effects of major ecosystem disruptions on fish communities and provide a suite of indicators that can be used to monitor for potential changes in fish productivity, especially in locations where it cannot be measured directly. The information generated in this project will assist the IISD Experimental Lakes Area in providing strong, scientifically based, guidance to industry and policy makers on the protection of fish communities and the freshwater ecosystems that support them.

Outcomes and recommendations will be formulated for consideration. This study will be presented at the CBN conference in June 2018 and the report will be made available to all participants and stakeholders through the CBN website and electronic avenues.

Structure-Property Relationships of Ethylene Polymers for Sealant Applications

Heat sealing is the most widely used sealing method in film packaging applications specifically in food industry. In this technique, two layers of film are melted and bonded together with the application of heat and pressure. In this project a rheological study (rheology and peeling) of a series of ethylene polymers will be performed to derive correlations between rheological properties and sealability for identification of optimum product properties. Good sealability of packaging of food products is crucial to public health as it ensures safety of the packaged goods and minimizes any leakage during transportation and handling. Good leak-free packaging also results in minimizing food waste for the consumer providing economic benefits and improves Canada’s sustainability efforts by reducing carbon footprint.

Évaluation du potentiel éco-énergétique d’un bassin hydrodynamique souterrain combiné à des panneaux solaires thermiques et une pompe à chaleur pour la production d’eau chaude, le chauffage et la climatisation de bâtime

La consommation d’énergie pour le secteur des bâtiments, supérieure à celle des secteurs du transport et de l’industrie, s’élève à environ 40% de l’utilisation d’énergie au niveau mondial. Plus de la moitié de cette consommation correspond au chauffage des édifices, la climatisation et la production d’eau chaude domestique. Ces besoins qui requièrent de l’énergie de faible qualité sont actuellement satisfaits le plus souvent par de l’énergie de haute qualité, telle que combustible fossile ou électricité. Le confort à l’intérieur des bâtiments peut être obtenu, en partie ou totalement, en utilisant la chaleur collectée dans le sous-sol ou par des panneaux solaires thermiques. L’efficience de ces sources d’énergie renouvelables augmente avec l’utilisation un bassin hydrodynamique souterrain, pouvant servir de stockage thermique et capable d’échanger de la chaleur avec le sous-sol.

Improving Research to Practice: Investigating the Feasibility of Community Organizations Developing Methods to Ensure Implementation Efforts Address the Needs and Priorities of the Spinal Cord Injury Community

Members of the SCI community must be involved in the process of designing and implementing SCI research to ensure the largest impact possible. SCI Ontario, an organization that supports people with SCI, is strategically planning their efforts to ensure research is used in practice. Understanding the needs and priorities of SCI communities and their families is a key step for their strategic planning. They aim to develop a method that can establish agreement among over 2500 SCI community members about areas of research that need be implemented in practice. Our research will help develop this method and examine the feasibility of using the method to establish agreement on priorities within the SCI community. As a whole, our research will contribute to a growing body of research that aims to ensure research is used in practice.

Dynamic cost modeling for mega projects

There is a recurring problem of cost overrun on mega engineering projects with a budgeted cost of $1 Billion or more. Examples of mega projects include dams, hydro electric projects, and high speed rail projects.

The basic reason for cost overrun can be attributed to underestimation of project cost, increases in material and labor cost, increases in financing cost, and problems with project management and environmental factors.

Construction Management deals with how to effectively plan and control construction activities such that the total project can be delivered within schedule and under budget. Using mathematical models, the best possible time and resource for each activity with consideration of both engineering and financial factors can be decided; as such, the entire project delivery is kept on time and under budget.

The basic reason for this thesis based research is to find ways to improve and apply proper analytical techniques in construction management and in financial…

An Analysis of Participatory Politics in Canada: Emerging strategies in media-based organizing

As young people increasingly move away from institutionally-driven “dutiful citizenship” (Bennett, 2008), political participation is no longer only defined by voting in elections, volunteering with civic associations and town hall meetings but increasingly manifests through participatory politics – peer-based acts like citizen journalism, podcasting, video production, art projects, tech-based activities, digital activism and lifestyle politics (vegetarianism, localism, boycotting). These approaches are expanding the boundaries civil society through new forms of citizenship. Indeed, as civic engagement shifts toward greater use of networked and mobile communication, there is an increasing demand among government agencies, non-profits, labour groups, and businesses for research into how participatory politics is being used to empower citizens and make government more accessible and accountable.
