This research is concerned with speaker diarization for the purpose of facilitating automated speech transcription. This problem has multiple depths depending on the prior knowledge provided to the system. The type and amount of information about the number and characteristics of the speakers can differentiate this problem in a range from a 1-to-N matching, where the voice is compared against different templates, to a clustering problem, where no prior knowledge is available.
This project is intended to development the technologies needed for three-dimensional (3D) printing of concrete constructions. This highly interdisciplinary research endeavor will draw on expertise in additive manufacturing, construction, materials science, and robotics to develop the key elements of 3D construction printing.
Terahertz spectroscopy for material imaging/sensing and characterization has received a great deal of attention over the past decade. Terahertz (THz) electromagnetic waves have frequencies in the range of 1012 Hz. Terahertz spectroscopy and imaging has many applications ranging from security, communication, food production, quality control for pharmaceutical industries, and cancer diagnosis. In the heart of every terahertz spectroscopy imaging system, there is terahertz transmitter and receiver pair antennas.
Customer satisfaction with an automatic car wash is highly dependent on the quality of the final drying phase, with residual water leading to spots and thus poor perception of performance. As such, Suncor Energy is committed to improving the drying phase of their next generation car wash facilities through principled design guidelines based upon scientific investigation of water droplet movement on a surface.
The cellular clearance pathway autophagy is required for degrading toxic proteins and damaged organelles, but is disrupted in many neurodegenerative diseases. During induction many autophagy regulators quickly localise to membranes from the cytosol. The Martin lab has identified palmitoylation, which involves the addition of the fatty acid palmitate to cysteine residues, as a potential regulator to direct autophagy proteins to membranes.
Mobility is an essential component of routine life for everyone. Walking and biking are two major transportation modes that help residents meet most or all of their daily needs. However, several mobility-related challenges occur as a result of weak maintenance of urban infrastructure such as sidewalks, bike lanes, and trails, which can decrease the safety of residents and may lead them to opt for vehicle-based transportation instead. One of the main reasons behind poor infrastructure maintenance is inefficiency of traditional inspection methods.
The food services industry is ripe for a technological revolution. Challenging labor conditions such as rising minimum wage, high employee turnover, and scarcity of skills among other things makes it increasingly difficult for restaurants to be profitable and scale their business effectively. Delivering a quality product in a consistent manner with today's low-pay low-skilled workforce is difficult at best; and the hallmark of success in the food services industry is quality and consistency. Furthermore, there are sanitation risks in the interaction of workers and the food they prepare.
Stroke happens when a blood vessel in the brain, is blocked by a clot (ischemic stroke) or bleed due to a vessel rupture (hemorrhagic stroke). The dielectric properties of healthy brain tissue are different from the one that is affected by stroke. In this study, these properties are measured in rat’s brain by an electromagnetic probe at frequency range 0.5-10 GHz. Subsequently, the changes are related to the type and level of brain injuries.
This project will assist Suncor Energy Inc. (Suncor) and Fort Mckay First Nation bring a Suncor mine site back to its original ecological state and environmental functions. To best achieve this, Fort Mckay First Nation and Suncor will work together to ensure the new restored site will support the traditional practices of Fort Mckay First Nation. The research team will analyze how Suncor and Fort Mckay First Nation work together, best utilizing both Scientific and intergenerational Indigenous Knowledge to restore this mine site.
Machine learning (ML) has recently achieved impressive success in many applications. As ML starts to penetrate into safety-critical domains, security/robustness concerns on ML systems have received lots of attention lately. Very surprisingly, recent work has shown that current ML models are vulnerable to adversarial attacks, e.g. by perturbing the input slightly ML models can be manipulated to output completely unexpected results. Many attack and defence algorithms have been developed in the field under the convenient but questionable Lp attack model.
