Multiphase flow represents a significant portion of the products transported in Canadian pipelines. Each of the many phases in a multiphase flow has its own unique characteristics, all of which will contribute to an added layer of complexity in the detection and subsequent localization of a leak. Current technology that compares pressure variations to identify a leak is unreliable for leaks that are less than 1% of the flow volume .
This project will aim at developing all-solid-state pouch cells (ASSPCs) based on atomic layer deposition (ALD) derived cathode surface modification, ultrathin solid-state electrolyte sheets (USESs) and flexible electrodes preparation.
The proposed research deals with automating of screw-propelled unmanned ground vehicles. This type of vehicle is capable of traversing any ground from hard to soft to water. Copperstone Technologies, an Edmonton, AB-based startup, has developed a series of human-piloted versions of this vehicle and used it for missions such as water sampling and surveying of bodies of water. The proposed research will be to develop onboard software to enable the vehicle to perform its missions autonomously, reducing operator tedium and increasing efficiency of the operations.
This project investigates substitution of fossil fuels with electricity from renewable sources for the purpose of reducing greenhouse gas emissions in British Columbia. Burning natural gas, gasoline, diesel and other petroleum products heats our buildings, drives out cars, and powers our industries. Electricity generated from hydro, wind, and solar power can provide those same services, but producing sufficient electricity from variable sources at the right time remains challenging.
Integrating a towed array (which consists of a very long tow cable and a line array of sensors) with an unmanned platform requires unattended operation of the array during deployment, operation and recovery. The objective of the proposed work is to create and demonstrate a towed array handling system on an unmanned platform which can operate without human intervention and ensure the towed array and cable can be deployed and retrieved unharmed.
Global pollution emissions contribute to climate change and are damaging to health. In many industrial applications that produce particulate matter, devices such as cyclones are used to separate and capture the particles from the exhaust gas. However, these do not capture the very small, but hazardous, particles and so expensive and energy-intensive secondary systems have to be added to the process. The industrial partner is developing a novel dynamic cyclone separator that has rotating vanes which improve the particle separation efficiency and allow capture of the fine particles.
Vibration of aircraft engine is the major contribution to the structure vibration in an aircraft. To reduce the cabin noise and improve the comfortability for air passenger, research design and analysis are desired in the engine technology. A critical component in eliminating the vibration in an aero engine is the squeeze film damper (SFD). Current SFD models are oversimplified to describe the practical issues related to the phenomenon of air entrainment and turbulence flows.
The application of autonomy is driven by a desire to safeguard lives by removing crew from dangerous environments and reducing the likelihood or impact of accidents arising from human error. State of the art Marine Autonomous Surface Ships (MASS) deployed for extended periods in complex in-land, coastal, and off-shore applications, must be able to address changes in their state, environment, and mission by adapting their mission plan.
Vehicle scheduling is one of the main planning problems for transit agencies. While it is relatively simple to solve in the deterministic and single-depot setting, these assumptions are unrealistic in real-world applications. Specifically, ignoring major sources of uncertainty (such as travel times) and making decisions over average predictions can lead to inferior schedules that incur additional costs and reduce the quality of service during execution. In this project, we consider the multi-depot vehicle scheduling problem under uncertainty.
The use of cinnamon as a flavoring agent and a remedy for metabolic, respiratory, and gynecological disorders is widespread throughout the world. Studies suggest that Ceylon cinnamon may be useful in the treatment of type 2 diabetes. This project will use a high-throughput method to analyze how a concentrated water extract of Ceylon cinnamon changes gene expression in human cells. The analyzed data will be compared to existing results from cells treated with the most common medication used for type 2 diabetes, metformin.
