Feasibility Study for Indigenous Women’s Second-stage Housing in Canada

The partner organization, the National Aboriginal Circle Against Family Violence (NACAFV), is conducting a Feasibility Study for constructing on-reserve second-stage housing. A section of the Study is on the technical aspects of this type of housing which is for women who wish to leave their homes permanently because of domestic violence. The design of the housing unit emphasizes safety and security because an ex-partner or ex-spouse may be stalking a woman—since one of the most dangerous times for women living in domestic violence is when they are leaving.

Instrumented based bridge evaluation

Bridges in North America are aging and need repair or replacement. Precise evaluation of load carrying capacity of bridges is a way to prevent economic and environmental impact due to replacement and repairs. Current method of evaluation requires the evaluator to make conservative assumptions on load and resistance of bridges. In recent years as technology develops, more precise data can be collected and be processed. Sensors can be mounted at carefully selected positions on bridges to provide sufficient data for more precise bridge evaluation.

Ultrasonic characterization of permafrost using an integrated machine learning poromechanical technique

Civil infrastructure (e.g. roads, embankments, pipelines and buried utilities) is severely impacted by frost action and permafrost conditions in cold regions. With earth’s temperature predicted to increase, the ground ice melts, and the induced soil shift and collapse jeopardize the integrity of infrastructure.

Enhanced rock formation characterization using Gas Expansion Induced Water Intrusion Porosimetry

A thorough investigation of the porous medium characteristics is essential in order to detect transport phenomena in porous media. Lab experiments such as Mercury Intrusion Porosimetry (MIP) and Gas Expansion (GE) on the core samples that are directly extracted from geologic formations are useful techniques to measure the porosity of the porous structure. However, the MIP test requires high cost and preparation time and the use of mercury causes the sample destruction.

Fast Awake OSA Screening and Characterization using Anthropometric and Sound Features

Obstructive sleep apnea (OSA) is one of the most common yet underdiagnosed sleep disorders. Undiagnosed OSA, in particular, increases the perioperative morbidity and mortality risks for OSA patients undergoing surgery requiring full anesthesia. OSA screening using the gold-standard Polysomnography (PSG) is expensive and time-consuming. This proposal presents four research projects/points to apply advanced signal processing and machine learning techniques on breathing sounds’ signals for screening OSA disorder during wakefulness.

Long-Term efficiency of horizontal closed-loop geothermal systems for seasonal freeze-back stabilization of permafrost

Wastewater treatment lagoons are practical and cost-effective systems for smaller towns across Canada to prevent wastewater seepage into the environment. Essentially all structures over permafrost that disrupt the natural winter temperatures contacting the ground surface initiates permafrost thawing over the long-term and this includes lagoons.KGS Group has been developing the concept of using conventional closed-loop geothermal systems within the sediments below the base of lagoon to allow a refrigerated solution to be circulated to freeze the soil below the lagoon.

Optimization of Bacteriophage Production for use in Treatment and Prevention of Bacterial Diseases in Swine

This project will involve research into the optimal production and purification methods for bacteriophages that are effective against bacterial infections in pigs. Cytophage’s bacteriophages will provide a highly effective, environmentally safe, and a cost competitive alternative to antibiotics in the pork industry. This project will benefit Cytophage by helping to advance our technology and product development.

Enhancement of methane oxidation in bio-based landfill covers by increasing aeration

Organic waste disposal in landfills can produce a massive amount of methane, which is a potent greenhouse gas contributing to global warming. Once the landfill is filled, it is usually capped by a clay cover or geomembrane that can trap methane but not reduce it. Changing a part of the conventional cover by compost to make a biocover provides appropriate conditions for methane consumption by methane-oxidizing bacteria. In the landfill environment, oxygen can diffuse into the biocover from the atmosphere and be used by bacteria; however, it cannot penetrate the compost deeply.

An AI-based climate impact assessment framework for infrastructure in northern Canada

The thawing of permafrost, due to climate change or alterations in the ground surface energy balance, poses significant threats to infrastructure and communities in northern Canada. A main step towards the design of resilient infrastructure is to assess the climate threat (exposure) and predict the response of the infrastructure (vulnerability). The stability of permafrost is correlated to the changes in the ground surface temperatures.

Perennial grains for fall grazing of beef cattle

Perennial grains, especially domesticated intermediate wheatgrass (IWG), are approaching commercialization as food crops. Due to the perennial nature of this crop i.e. multiple seed harvest (years) off of a single planting, grazing of post-harvest regrowth in the late fall would provide added value to beef producers, helping to sustain Canada’s beef industry.
