Optimal Winter Road Maintenance (WRM) Operations

The proposed research aims to find the optimal application rates of liquid chemicals which are applied to a road surface before and during a snow storm. These chemicals are used to accelerate the melting of snow and ice. The effects of various factors such as traffic, pavement temperature and other environmental factors on the performance of these chemicals will also be investigated. In addition, alternative types of machinery currently used to distribute solid chemicals on the roadways will be compared to examine their effectiveness.

Feasibility of a pressure retarded osmosis process for Quebec electricity generation

Osmotic power or salinity gradient energy is one type of the renewable energies which is produced by mixing fresh water with salt water. This new environmental friendly energy based on the advantages such as carbon dioxide free and generating power continuously seems to be a good option in which to invest as it will be highly beneficial to Quebec. This project looks to develop expertise related to osmotic power. A pressure retarded osmosis (PRO) power test unit will be designed and installed in Quebec. This will be the first osmotic power system in North America.

Development and Validation of the Next Generation Simulation Platform for High-Rise Buildings

Recent years have witnessed a boom in the construction of modern high-rise buildings in megacities around the world. Since many of these megacities are also located in seismically active regions, it is important to design a high-rise building that can effectively withstand both wind and earthquake loads. Nonetheless, in current practice, the design of high-rise buildings for wind and earthquakes is done independently. Hence, there is an urgent need to develop a set of integrated design guidelines for both wind and earthquake loads.

Development of a Decision Support System for FTTH Installations

In preparation for increasing its deployment of last-mile fibre, TELUS has engaged the University of Alberta to study the most efficient and cost-effective installation methods for Fibre-to-the-Home (FTTH) deployment where there are no existing telecommunications rights of way. The methods we will explore are divided into two categories: 1.) Direct Buried Methods (micro-trenching, Horizontal Directional Drilling, piercing and plowing. 2.) Utility Sharing (installing optical fibre via existing utility lines).

Research and Development of Ultra-portable Modulus Structures

Canada is considered to be one of the leading nations in nature conservation. Greenheart specializes in the design and construction of aerial trails. University of British Columbia (UBC) is a world renowned institute for structural engineering research. This Mitacs Intern Program is intended to create a robust research program that allows UBC researchers to collaborate with Greenheart to design ultra-portable, reconfigurable and lightweight structures which can be used for education, enjoyment, promotion and preservation of our environment.

Dynamic analysis of tailings dams using advanced constitutive models

Tailings are the residual material produced during the extraction of minerals from mined ores and are usually produced in slurry form. Tailings are retained in impoundments that depending on the type of their structures could be vulnerable in terms of stability under different loading scenarios such as earthquake loading. The consequences of the failure of tailings dams are heavy economic losses, environmental degradation and, in many cases, human loss. These factors justify investment and detailed study on proper analysis and design of tailings dams.

Treatment of cyanobacteria by flotation

The AquaDaf® is a high speed clarifier for the treatment of surface water with algae. The objective of the project is to perform a laboratory study permitting the optimization of the treatment of cyanobacteria with Aquadaf and in particular to establish a protocol to compare the removal rates of cyanobacteria by flotation and to verify the capacity of the process flotation to avoid cyanobacteria lysis which would liberate toxin release.

Evaluation of organic anti-icing agents for winter maintenance of transportation facility

Considering the facts that road salts pose significant environmental impacts and infrastructural damages, this research will evaluate the organic products for snow and ice control for transportation facilities. An extensive field tests will be conducted focusing snow melting performances of the organic liquids over regular bine over an expected ranges of weather and other external variables in a parking lot in the winter season.

Design Guidance for Cross-Laminated-Timber Structures using Self-Tapping-Screws

There is an acute need for research to develop value-added applications for wood and wood products such as Cross-Laminated-Timber (CLT). One prominent target area are mid- and high-rise structures. In seismic regions, such as Western Canada, connectors must provide ductility to otherwise rigid building systems composed of CLT panels. There are a number of options available, one of the most promising are Self-Tapping-Screws (STS). The objective of the project is to develop design guidance for CLT assemblies connected by STS for large structures, considering seismic loads.

Sustainable and Resilient Neighbourhood Design

This research investigates how a neighbourhood in London, Ontario may be designed to be both sustainable and resilient, where “resilient” means capable of dealing with future shocks and stresses. One major future shock/stress will be climate change impacts, such as extreme temperature or precipitation. This research will also conduct preliminary energy modelling of a simplified community using both current and future London temperatures.
