Atomic Layer Deposition (ALD) is a popular tool for the deposition of thin film materials that are common in solar cells, sensors and display technologies. However, the need for a vacuum environment and slow material growth rates restricts ALD applicability in large scale commercial and industrial materials production. Atmospheric Pressure Spatial Atomic Layer Deposition (AP-SALD […]

There is a need for higher functioning prosthetic components available at a lower cost. The Niagara Foot™ is a low cost, high function energy return prosthetic device targeted towards developing regions. The system is comprised of keel and cover components developed through partnership of Niagara Prosthetics and Orthotics International (NPOI) and Queen’s University. A new […]

Our laboratory has developed an improved model of large scale offshore wind turbines systems for controller design. This model captures all the important dynamics involved in the system such as the 3 dimensional motion, wave disturbance and wind effects, allowing to design advanced control techniques to enhance the efficacy of the wind turbines and increase […]

Composite materials have been increasingly used in today’s aerospace products such as Bombardier CSeries and Boeing787 airplanes. A widely used composite manufacturing process is Automated Fiber Placement (AFP) utilizing robotics, precision control, and other high tech tools. Quality requirements for aerospace products are at very high level for product safety and performance. Statistical quality control […]

Counting coins, with speed and accuracy, has been a challenging issue for banks and stores. People used to count coins manually before the arrival of coin counting machines. The process of counting coins manually is a very time consuming and tedious job. Moreover, mistakes are likely to occur due to various reasons such as fatigue, […]

The objective is to develop a real-time fraud detection algorithm for a large E-commerce company based on construction of a robust reference model from normal multivariate data. To accomplish this, we propose to leverage machine learning techniques, such as reinforcement learning, in combination with stochastic modeling techniques such as Hidden Markov Models, to provide both […]

Increasingly prevalent patient violence within the dementia population is a challenge to long term care providers. Violent incidents can lead to serious musculoskeletal and neurological health complications. I propose to use video surveillance and a novel brain monitoring system in a care facility-based elderly population, to monitor violent episodes and brain vitality after incidents. This […]

While GPS has become the de-facto standard for positioning, its availability and accuracy are hindered by attenuations. Positioning using vision-based systems is becoming an attractive solution due to its infrastructure-less architecture and its wide integration into portable devices. This work aims to develop novel vision-based algorithms for head-mounted sensors that would solve various problems such […]

Bell Helicopter Textron Canada Limited and Pratt & Whitney Canada have all initiated research projects on Additive Manufacturing (AM) processes. Although applications are different, all companies are facing the same challenges, including the lack of a mature Canadian supply chain. The purpose of the current project is to bring together the whole value chain (Certification […]

In recent years, the remediation of residual and historical soil and groundwater contamination has become a priority for the oil and gas industry. Due to increasing public awareness and media attentions, the exploration and implementation of cost-effective and environmentally friendly approaches for remediation of contaminated sites has increased significantly as a mechanism to demonstrate social […]

“Building integrated photovoltaic–thermal array (BIPV/T) incorporated within a building structure is a system that combines the roof/facade, photovoltaic cells and thermal collector as an all-in-one product instead of installing each individually. BIPV/T effectively replaces conventional building materials and is more cost-effective than having several separate products, and installation of the BIPV/T system can be implemented […]

Liquefied natural gas (LNG) has up to 20% CO2 and 90% NOx fewer emissions than diesel; making it a cleaner alternative fuel for mobile applications. LNG has high volumetric energy density and is cost effective ($0.5 cheaper than diesel gallon equivalent). However, LNG is stored at low temperatures (-162ºC) and releases boil-off gas that contributes […]
