Groundwork for Modeling the Effects of Climate Change on the Lower Churchill Hydroelectric Development

Nalcor Energy is in the planning stages of the Lower Churchill Hydroelectric Generation Project, expected to cost between $ 6 and 9 billion dollars. Due to the scale (over 2800 MW) and potential lifespan of this project, consideration needs to be made about the effects of climate change on the available water in the Churchill River. This internship is the jumping off point for a working relationship between Memorial University of Newfoundland and Nalcor Energy.

Digital modelling of DC plasma torches (Part 2)

The use of plasma torches for the gasification of waste products enables the transformation of waste into clean energy with no residual by-products. As a result of the extremely high temperatures generated by plasma torches (from 5,000°C to 20,000°C depending on the type of gas used), torch and reactor modelling represent a technological challenge for designers. Digital modelling of the plasma flare and the electrical arc in the plasma torch will contribute to a better understanding of the degradation of the torch’s internal components.

Determining road sub-soil anisotropic resilient modulus on site using a self-boring pressure-meter

The proposed research initiative consists of on-site and laboratory tests to evaluate the compaction quality of road sub-soils. To that end, we will use a self-boring pressure-meter to determine the on-site resilient modulus and compare it with results obtained by the Quebec transportation department using triaxial equipment for deviatoric loading in accordance with the LC-22-400 method. Studies demonstrate that the resilient modulus is an essential parameter for road design and analysis.

Design and implementation of a plasma power source

This project calls for the design and implementation of a power source of 20 kW and 600 V. The power source will serve several functions in the labs at Atlantic Hydrogen Inc. (AHI), chief among which is to create thermal CC plasma with current control capability. The source will consist of a static converter that converts alternating current into direct current (AC-DC), a tri-phased transformer to reduce tension throughout the network and ensure galvanic isolation, several transducers (current, tension), control circuits, and a dedicated digital processor.

Analysis of Plug-in Hybrid Electric Vehicles in Distribution Networks

Plug-in Hybrid Electric Vehicles are hybrid vehicles with large batteries that are capable of travelling on electricity but still maintain the reliability of an on‐board internal combustion engine for extended trips. The batteries will typically be recharged from a standard household outlet, thus increasing the demand for electricity. It is important to understand and predict how these vehicles will affect the operation and planning of networks in British Columbia.

3D building/structure model reconstruction using multiple aerial images

The objective of this research is to propose and implement a set of new methodologies to create a 3D hazard map that includes models of structures and obstacles in the airport area. The project uses multiple oblique and nadir views high resolution aerial imageries (pictometery images) to reconstruct such models. Various views of an obstacle are combined using image processing and computer vision algorithms to create an accurate 3D wireframe model of the obstacle. The building blocks of the project include two sub‐systems.

Replacing mercury use and improving gold recovery in artisanal operations

This study aims to improve a process to recover gold in artisanal mining operations by treating a gravity concentrate with cyanide in a closed circuit in a ball mill, trapping gold particles in a capsule of activated carbon in the mill. The main innovation of this process is the use of the activated carbon inside the mill, with no need to remove the balls. Cyanide is safely degraded when the process is complete, with no residual damage to the environment, when the process is carefully applied.

Mattamy Homes Green Initiative Program

This research project proposes the exploration of various mechanical systems configured in two residential homes in Milton, Ontario. The primary goal is to determine the energy consumption and monetary costs associated with integrating new technologies of both heating and cooling requirements of a new home. Refinement of previously collected data and software modeling are keys to providing successful long term projections on potential savings in energy usage and economic payback periods.

Innovative Technology for Bioremediation/Composting of C&D Wood Waste

Manufactured and coated wood (MCW) is generated by the construction and demolition (C&D) industries. At present, some MCW is ground and utilized as daily landfill cover. However, the Province of Nova Scotia would prefer to see this move away from landfill and be utilized as a value added marketable product. Current estimates suggest that there is 175,000 tons of C&D materials generated annually. Of that, 40% is estimated to be wood material consisting of clean wood, MCW, pressure treated, creosote timbers and laminates.

Debugging in the Real-time Systems with DTrace

In order to bebug a system, one requires information from both offline and run time slates of the system. In more cases the information required to trace a problem does not correspond to the information available from the output provided by the system. Thus, additional probes must be inserted in order to achieve the required information. Herein lays the problem since the probing could perturb the system leading to side effects known as Heisenbugs. One major reason for the occurrence of these bugs is due to lack of information a developer has on the effect of probing.
