The goal of this proposal is to clarify the reasons for an increased burden of serious bacterial infections caused by two common pathogens: Haemophilus influenzae and Streptococcus pneumoniae in Canadian First Nations. Methodology includes comparative analysis of the critical parameters of naturally acquired immunity against these pathogens in adult First Nations individuals living in two different geographical areas with diverse environmental conditions (Southern Ontario versus Northwestern Ontario).
Fatal personnel injury due to accidental contact with high voltage lines and equipment happens from time to time despite of substantial efforts put in place by industry to minimize the risk. The objective of the project is to identify effective concepts, techniques and solutions to reduce the risk of inadvertent contact with high voltage equipment for both Hydro workers and the general public. We will identify the most common scenarios of potential fatal encroachment based on the data obtained from BC Hydro.
In this project, mathematical models for estimating the behavior of electric appliances are derived using field measurements. These models are then used to estimate the amount of energy savings that can be achieved on each area, depending on the types of customers connected to each particular electric circuit. The outcomes of this project can be used in identifying the best locations in terms of achievable savings for implementing the energy conservation techniques within the BC Hydro system. Saving energy can benefit the environment and contribute in addressing the global warming issue.
The research will comprise effects of penetration of photovoltaic on existing distribution network. This will include power quality, voltage stability and customer load when there is a penetration. The graphs would display and let the utility organization know till what level the penetration should be done on a distribution network. The advantages and the need for doing the research is that the load can be distributed from the utility to the photovoltaic panels which are installed and the utility would have to generate less by the existing means. In this case by means of Hydro.
The project performs comparative study of simplified and rigorous approaches to analysis of lightning strike discharge through complex 3D structures of the power line towers and their grounding systems. Simplified models of the commercial tools such as PSCAD and TFlash will be compared to the new rigorous electromagnetic model (EM) based on full-wave algorithms analysis.
Radiolysis of water produces hydrogen, oxygen and hydrogen peroxide, which can be deleterious to system components. The radiolytic production of these species can be mitigated through appropriate chemical dosing with small amounts of dissolved hydrogen or oxygen-scavenging chemicals such as hydrazine. Corrosion of carbon steel components in the End Shield Cooling system of a CANDU reactor consumes oxygen, which can also keep the system in a state of net radiolytic suppression.
Currently, developing 3D pipeline GIS (Geographical Information System) with 3D data interoperability is not only highly required by pipeline industry but also essential for building 3D SDI (Spatial Data Infrastructure). This project proposes a novel approach to develop a new 3D GIS Web Services framework and components that is suitable for 3D Pipeline GIS and 3D SDI.
Increasing global energy demand coupled with efforts to reduce our carbon emission has pushed for improved energy efficiency in many areas. One area in need of improvement is residential and commercial buildings. Specifically, the demand-side energy management of commercial buildings can be improved significantly with improved control. With the addition of on-site renewable energy generation such as Photo-Voltaic and energy storage, a large commercial building can be optimally controlled to provide reliable, stable power while maintaining minimal wasted energy.
This proposal builds on 5 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 faster and more accurate urban waste heat mapping and refined waste heat metrics.
SaskEnergy developed an in-situ remediation program using a soil vapour extraction (SVE) system to facilitate recovery of petroleum hydrocarbons at the Cantuar Site. One of main problems associated with this program is the deficiency in the knowledge of process control based on the fate and transport of contaminants, and effective studies for assessing the environmental and health risks/impacts.
