An evaluation of geohazards arising from gas hydrate dissociation in Canadian continentalmargins

The long-term research goal of the research group is to contribute to the fundamental state-of-knowledge on gas hydrates by improving methodologies and techniques for characterization, assessment, and development of natural gas hydrate accumulations. The short-term goal and main objective of the present proposal is to characterize and assess submarine geohazards evolving from gas hydrate instability.

Biomechanical Factors as a Diagnostic Aid for Aortic Pathologies

We have developed a software tool that could be used as stand-alone software, or could be implemented in a vascular diagnostic suite (for example within the post-processing software that accompanies most CT and MR scanners). The tool would allow surgeons and radiologists to better evaluate the current state of the aorta under examination and the likelihood of rapid enlargement, rupture or dissection. This added tool would be used together with the existing vascular diagnostic tools, such as diameter and rate of growth providing an improved and more effective diagnosis.

Assessment of air quality using remote sensing technology for Alberta’s oil sands region

The objectives of this study are:

• To assess the feasibility of using satellite remote sensing technology to measure trace gases and aerosols over northern Alberta and to study the transport of biomass burning emissions and its impact on air quality over northern Alberta.

 

Methodology:

Control of point source low volume methane emission using methanobiofilteration technology

The research project identified here falls under the category of “clean energy technology”. Methanobiofiltration (MBF) is a new technology for the treatment of waste methane gas using a biological process, thus contributing to the reduction of the environmental impacts of current energy technologies. The lack of a complete technology package needed for various industry sectors has hindered its large-scale application in Alberta.

In-plane Performance of Masonry Shear Walls Year Two

A. Overall Project Objective Recent research at the University of Calgary has focused on shear walls and on evaluating the influence of various parameters on in-plane shear capacity. The reason for this is that, for example, while it is recognized by most researchers that compression on walls increases the shear strength of masonry, the quantification of this effect has been reported to vary from 40 to 70% [1,8] and the factors adopted by various design standards range from 0.25 up to 0.4.

The Effects of Active Road Signs on Road Safety and Driving Behavior

This project seeks to evaluate the benefits of deploying active road signs on road safety and driving behavior. Different types of iluminated and traffic responsive traffic signs will be considered, under urban and rural setting. Two case studies will be analyzed for this purpose. The company expects to identify demonstrate that their products are beneficial to improve road safety. This represents an initial stage of the larger project. Eventually, the industrial partner seeks to develop a global framework for deployment of active traffic signs based on several factors (e.g.

Arterial travel time reliability and travel time prediction

The objectives of this study are: 1) examining the reliability and distribution of arterial travel time collected from probe data derived from two different modes, 2) examining the factors that have significant contribution to arterial travel time reliability, and 3) predicting the travel time for urban signalized arterials for a given scenario. The travel time reliability analysis will be developed for vehicular traffic and for the transit modes.

Multimodal Safety Analysis of the implementation ofrectangular rapid flashing beacons (RRFBs)

With the increased number of non-motorist related crashes, there is a growing need for accommodating the safety of active modes in urban areas. The City of Calgary has recently installed rectangular rapid-flashing beacon (RRFB) at several locations in the City in an attempt to improve cyclists and pedestrians’ safety. RRFB use dual rectangular LED lights to display intermittent rapid flashes similar in operation to emergency flashers on police vehicles. These devices were shown to assist motorist yielding behaviour at some particular locations.

Calgary’s water main asset management using predictive models

All water utilities, engineering consulting firms, and provincial and federal departments in Canada responsible for design, operation, maintenance, rehabilitation, and development of a water distribution system would directly benefit from the outcomes of the proposed research. Efficient and effective asset management of water distribution infrastructure is a demand driven issue for any water utilities due to resources and budget constraints. The proposed research is targeting any water utilities under a good notion to improve asset management practices in Canada.
