Canada owns the largest heavy oil and bitumen reserves in the world. Unfortunately, extracting these hydrocarbons is difficult due to their high viscosity. Currently, the most popular strategy is to heat the bitumen using steam, but steam injection can be inefficient and is not suitable for all reservoirs. Radio frequency heating offers a flexible and efficient solution, but its implementation has been marred by the dynamic underground environment of the reservoir. Here, the changing electrical properties of the reservoir can lead to uneven heating or equipment damage.
Laura Solis Rodriguez is about to enter her final year at Mexico’s Instituto Tecnológico y de Estudios Superiores de Monterrey, where she’s a marketing and communications student. Because of her specialization in advertising photography, Laura was used to thinking about objects in terms of how to market them to potential customers. She didn’t expect to apply her photography skills to archeological artifacts!
Oil reservoir souring is the production of toxic hydrogen sulfide by sulfate-reducing microorganisms (SRM) through naerobic respiration supported by organic electron donors present in oil fields. In recent years, nitrate injection has merged as a promising green biotechnology that has been proven effective in controlling sulfide production in oil fields. This strategy relies on inducing nitrate-reducing bacteria (NRB), which can outcompete SRM for organic lectron donors.
The objective of this project is to improve long-term planning of Alberta's electricity system infrastructure in collaboration with an industry sponsor, Alberta Electricity System Operator (AESO). The project aims at engaging stakeholders in a regional planning exercise in southern Alberta by a detailed exploration of their perspectives when evaluating energy system alternatives. This was identified by AESO as being a pressing gap in their current practice.
The most common solution to pectus carinatum is surgical. As braces begin to be developed that have been seen to reshape the chest successfully it becomes important to understand the effectiveness and optimal design thereof. Braceworks, has managed to create a low profile prototype brace which contains a protocol on how long to wear the device. However, only qualitative data has been collected and very little quantitative. Therefore, the project seeks to gain more information on what this protoype does to the chest wall as a whole, and how much force it applies to the chest.
Slab bands are a common structural system in North America due its general economy. At the slabband/column connection, unbalanced moments are being transferred that could lead to a common failure mechanism termed punching shear failure. This type of failure occurs when the column and a portion of the slab punches through the remaining slab. Thus, it is critically important from a design prospective to identify and quantify how these unbalanced moments are being transferred, specifically as shear stresses at the slab-column connection.
This proposal builds on 4 years of research in the award winning HEAT (Heat Energy Assessment Technologies) project. Every year, billions of GJ of wasted heat leave millions of buildings in thousands of cities world-wide. In an effort to support urban energy efficiency, this research proposes four novel image post-processing techniques to improve/ verify the geometry, radiometry and the processing of large volumes of high-resolution airborne thermal infrared (TIR) imagery. Results are expected to enable more accurate urban waste heat mapping and refined waste heat metrics.
The proposed project focuses on the research & development of efficient electrode materials for use in an electrochemical process that produces high-value chemicals for use in a variety of industrial applications. As an electrochemical process, significant portions of the production costs are attributable to electrical power consumption; therefore, improvements in energetic efficiency would result in appreciable reductions in production costs.
A novel transmitter architecture which presents more power efficiency than that of the transmitters being used currently in mobile communication base stations is proposed in this research project. The result of this research fills the gap between the theoretical idea behind this transmitter structure and its practical usage in cellular network base stations. This transmitter can operate over a wide frequency range and with different mobile communication signal standards very power efficiently while maintaining the quality of the transmitted signal.
In order to develop good physical skills, people need feedback on the performance of those skills. Analysis based on accurate observation is a key tool for improving future performance. Performance analysis is about creating a valid and reliable record of performance by means of systematic observations that can be analyzed with a view to facilitating change. Use of video recording is one of the most effective ways to observe and analyze performance.
