Hybrid fuzzy system dynamics model for analyzing the impacts of interrelated risk and opportunity events on project contingency
Download2020-07-23
Siraj, Nasir B., Fayek, Aminah Robinson
Traditional risk analysis techniques are ineffective for capturing the dynamic causal interactions and subjective uncertainties involved in assessing risk and opportunity events since they treat risks independently and rely on the availability of sufficient historical data. In this paper, a...

Tiruneh, Getaneh Gezahegne, Fayek, Aminah Robinson
The majority of competency and performance modeling methods available in the literature are deterministic conceptual, statistical,and/or regression models that cannot capture the subjective uncertainty, complex, and nonlinear relationships inherent in construction, whichmakes accurate prediction...

Identifying Critical Corridors During an Area-Wide Disruption by Evaluating Network Bottleneck Capacity
Download2021-07-24
Ohi, Sabrena Jahan, Kim, Amy M.
This paper applies the min-cut max-flow theorem combined with a grid cell disruption method over a large transportation network, to identify the importance of network locations in providing travel capacity when a community is evacuating (say, from wildfire). We develop metrices that look at the...

Impact of lime treatment on tailings dewatering and cap water qualityunder an oil sands end pit lake scenario
Impact of lime treatment on tailings dewatering and cap water qualityunder an oil sands end pit lake scenario
Download2021-01-01
Oil sands tailings have a limited ability to dewater and can also release toxic water, so finding a cost-effective tailings reclamation strategy has been challenging. End pit lakes (EPLs) are being examined as one potential approach to reduce fluid fine tailings (FFT) inventories for the oil...

Veronica Wambura, Stephen D. Wong
Disasters caused by extreme weather and human-initiated events continue to disproportionately impact vulnerable and underserved communities. While these communities often rely on public transit to travel, most North American jurisdictions still lack a fundamental understanding of equity-centered...

Incorporating the impacts of climate change in transportation infrastructure decision models.
Download2020-04-01
Historically an important transportation corridor in the Northwest Territories, climate change has shortened the duration of the Mackenzie River’s navigational season. Communities rely increasingly on airlift as the growing volatility affects barging operations, leading to higher overall freight...

Indigenous microbial communities in Albertan sediments are capable of anaerobic benzene biodegradation under methanogenic, sulfate-reducing, nitrate-reducing, and iron-reducing redox conditions
Indigenous microbial communities in Albertan sediments are capable of anaerobic benzene biodegradation under methanogenic, sulfate-reducing, nitrate-reducing, and iron-reducing redox conditions
Download2020-01-01
Alberta is a major center for oil and gas production, and correspondingly harbors hundreds of unresolved contamination sites by environmental hazards such as benzene (C6H6). Due to its cost-effectiveness, bioremediation has become a promising strategy for C6H6 removal. Contamination sites...

Indigenous microorganisms residing in oil sands tailings biodegrade residual bitumen
2018-01-01
Xiaoxuan Yu, Korris Lee, Bin Ma, Evelyn Asiedu, Ania C. Ulrich
The purpose of this study was to determine the capacity of indigenous microbes in tailings to degrade bitumen aerobically, and if acetate biostimulation further improved degradation. Fluid fine tailings, from Base Mine Lake (BML), were used as microbial inocula, and bitumen in the tailings served...

Influence of Penetration Rate and Indenter Diameter in Strength Measurement by Indentation Testing on Small Rock Specimen
Download2015-01-01
Mohammad Haftani, Bahman Bohloli, Alireza Nouri, Mohammad Reza Maleki Javan, Mahdi Moosavi, Majid Moradi
Indentation testing has been developed as an unconventional method to determine intact rock strength using small rock specimens within the size of drill cuttings. In previous investigations involving indentation testing, researchers have used different indenter stylus geometries, penetration...
