Embodied Carbon Study of New Residential Buildings in Southern Ontario

The built environment accounts for over one-third of annual global carbon emissions, with approximately one-quarter resulting from ‘embodied carbon’ that is released during the raw material manufacturing, transportation, construction and end of life phases of built assets. Given the continued growth in new build construction and the critical need to limit climate change, further analysis is required to identify strategies that can reduce embodied carbon emissions in the built environment. In partnership with Podium Developments, this research project will assess the key drivers of embodied carbon in new multi-unit residential buildings in southern Ontario. It will then identify a set of alternative building design strategies, and the extent to which these could reduce embodied carbon in the selected projects.

Universal Minerals Database for identification of minerals to be used for exploration, industry, and academia: Time-gated Raman spectral libraries for fluorescent minerals

Raman spectroscopy is used for analysis of minerals for two main reasons: 1) instrumentation sensitivity, and 2) “libraries” of spectra used as reference for a range of minerals. However, even the industry-best Raman libraries have <3000 out of the>5000 approved mineral species, partially due to the fluorescence that obscures Raman measurements. Fluorescence and Raman effects have different lifetimes which can be used to shutter the fluorescence, and pass the photons emitted by the Raman effect to a detector. Time-gated Raman spectroscopy will be used to build a library of minerals that have been excluded from existing libraries. This application will be used to examine minerals related to potash, lithium, and uranium exploration and environmental management. These emerging Raman libraries will also be made available for the agriculture and high-tech materials sectors. This project will establish the standard for Time-gated Raman spectroscopic libraries with the only high-throughput Time-Gated Raman spectrometer in Canada. Prairie Tide Diversifies and the Saskatchewan Structural Sciences Centre will cooperatively offer analytical service under ISO 17025 to clients.

ML/DL for Action Detection in Movies for Haptic Effects Generation

Haptic signals are sent to movie or home theater motorized seats in order to create an immersive environment to the viewer by applying movements and vibration to the seat. The haptic signals are currently created using a tedious manual design process. These signals need to be matched and synchronized to specific actions in the movie, such as gunshots or car crashes for instance. This project consists in developing machine learning models to automatically detect the appropriate actions in movies that need to be enhanced with haptic effects. The models will identify the events in the movie and provide their exact timing. This information will be used by the company to synthesize automatically the right haptic effect for each action detected.

Apprentissage par renforcement pour la planification de la production dans le réseau électrique québécois de 2035

À Hydro-Québec, le « Plan de production » est la stratégie de gestion du parc de centrales mise en place afin de répondre à la demande en électricité à court terme (horizon de 30 jours) et à très court terme (horizon de 24 heures). L’objectif du projet est d’optimiser la prise de décision sur les horizons très court terme et court terme sur le réseau de transport québécois de 2035. Différents scénarios doivent être étudiés, dans un contexte où les ressources de production sont majoritairement hydroélectriques, mais où on doit aussi prendre en compte l’intégration d’autres technologies telles que les éoliennes, les batteries à grande capacité et l’hydrogène vert. Plus spécifiquement, le stage proposé vise à insérer une couche d’optimisation basée sur l’apprentissage par renforcement (profond) afin d’améliorer cette prise de décision et la qualité globale des solutions trouvées tout en réduisant le temps de calcul.

Wireless Connectivity in the Coastal Incident Management System

Marine emergency incidents pose major environmental risks that are detrimental to the ocean ecosystem and present significant dangers to both people and property. Current response options are very limited and the existing tools to deal with nearshore environmental spills are neither timely nor efficient. SHIFT Environmental is developing innovative solutions as part of a Coastal Incident Management System (CIMS) to enable local communities such as coastal First Nations to respond quickly and to carry out search and rescue operations. In the CIMS system, there are three main offshore field elements: an unmanned surface vessel (USV), an unmanned aerial vehicle (UAV) and the SHIFT mobile control module. The proposed MITACS project focuses on the wireless connectivity of the three offshore field modules that are critical to the operation of CIMS. The unique air and ocean environment where both the transmitters and receivers are non-stationary and subject to impacts from waves and weather, the lack of pre-existing infrastructures, and the stringent power and payload restrictions make the communications challenging. The network topology, the wireless protocols, the choice of commercial off-the-shelf wireless solutions, the integration of the communications module to the field modular systems will be designed, analyzed, implemented and

Evaluate the impact on transmission dynamics and cost-effectiveness of pertussis booster vaccine for Canadian adolescents and adults

Pertussis or whooping cough is caused by the strict human pathogen B. pertussis or Bordetella parapertussis and is a highly contagious, potentially life-threatening respiratory tract illness when it occurs in unprotected infants. Despite the introduction of acellular pertussis (aP) vaccines and great initial success of the immunization program, pertussis outbreaks were reported in adolescents and adults in Canada since 1993. This trend was demonstrated as shift in pertussis epidemiology from infants and young children. Further, pertussis in children associated with adolescents or adults cases have been reported in developed countries, in which siblings and adults were identified as the main source for the transmission of pertussis to young unvaccinated infants. This program represents a timely response to the urgent public health concern to understand the introduction of different aP vaccine (booster) recommendations (for <65 years old and>=65) on the transmission dynamics of B. pertussis, and cost-effectives in Canada by developing and testing the comparative age-structure and cost-effective economic models. This program is expected to provide recommendation about acellular pertussis immunization policy and practice guidelines. TOBECONT’D

Feasibility Study of using Fiber Optical Sensor Technologies for Detecting Flow-induced Vibrations on Feeder Pipes

A nuclear reactor to a nuclear power plant is the same as the heart to a living human. Safe operation of the plant is directly related to the health of the reactor. Just as human heart where blood circulates through to deliver oxygen to the other parts of the body, coolant passes through the reactor core and distributes the heat to a other parts of the nuclear power plant to drive the turbine-generator for electricity generation. Similar to blood vessels (arteries and veins) in near the heart, there are many pipes connected to the reactor core. Just as our blood vessels, if there is a break or a blockage, the consequences are disastrous. In fact, it can cause a serious accident. The objective of this project is to explore new technologies based on fiber optic sensors to provide early detection of such events to improve the safety of nuclear power plants in Canada. This project will focus on literature review and feasibility studies.

Air-stable halide perovskite thin films and quantum dots for solar energy harvesting devices

The extensive use of coal-based energy sources to cater to industrialization and rising population in the last several decades is leading to global warming and severe climate changes, which has motivated researchers to harness renewable energy resources. Among the existing renewable energy resources, solar energy is the most viable candidate to reduce fossil fuels in the near future. In this aspect, metallic halide perovskite (MHP) material has seen rapid advancements both for the solar cell as well as photocatalysis application, wherein the solar energy is used for a chemical reaction that transforms water and/or CO2 into portable high-density fuels such as hydrogen, methane and methanol. However, the ambient instability of MHP materials also complicates device fabrication requiring the use of expensive and cumbersome inert ambient glove boxes to protect the MHP active layers of optoelectronic devices from moisture and oxygen. The current challenge therefore lies in improving the environmental stability of MHP. Our solvent free perovskite synthesis process could address the stability as well as demonstrates an efficient candidate for both photovoltaics and photochemical application without use of any inert glove box.

Localized node-based collection of wastewater samples for molecular monitoring of public health markers

Wastewater testing can measure levels of COVID-19 in a population that is contributing to the sewer system being monitored. This testing provides an early warning signal of the burden of COVID-19 in municipalities, independent of clinical testing. Calgary based start-up company C.E.C. Analytics (CEC) has developed a compact wastewater autosampler that enables this kind of testing to be conducted from city-wide to neighbourhood to individual buildings. CEC’s expertise in sewershed engineering is combined in this application with Mitacs interns and university researchers with the necessary expertise in microbiology and molecular biology. As a start-up company with new technology, CEC’s involvement in this project provides connection to a multidisciplinary team that can collect, test and report results using WW collected with the autosamplers. The data coming from the project will be used to improve the design and programming of the autosampler technology to improve the utility and robustness of the devices for CEC’s diverse clients.

Nanomaterials Based Electroencephalography Electrodes for Auditory Attention Decoding in Hearing Assistance Devices

This project aims to form a collaboration between Queen’s University with AAVAA Inc. AAVAA is developing hearing aids with capability of attention detection decoding by recording and analyzing brain waves, which are recorded non-invasively through the skin around the ear and within the ear canal. One of the main components of this system contributing to recording electroencephalography signals (brain waves) is its electrodes. Electrodes are interfaces between the system and skin.

The goal of this project is to develop dry soft sensors that can form stable and conformal contact to the skin from around and in the ear for reliable long-term recording of brain waves. Our goal is to address one of the main challenges in the field of biosignals recording using dry electrodes, which is minimizing and avoiding motion artifacts and reducing skin-electrode interface impedance.
