Uncertainty in Probabilistic Open Pit Slope Stability Analyses: Implications for Reliability-Based Designs
DownloadSpring 2024
The presence of uncertainty is acknowledged in various fields of Engineering. Also, there are many sources of uncertainties. In geotechnical engineering, probabilistic slope stability analysis (PSSA) is a tool used to quantify parameter uncertainty. It achieves this by considering any strength...

Villalba Matamoros, Martha Emelly
Analysis of uncertainty in ore reserves impacts investment decisions, mine planning and sampling. Uncertainty is evaluated by geostatistical simulation and is affected by the amount of data and the modeling parameters. Incomplete uncertainty is given because the parameter uncertainty is ignored....

Uncertainty in well-to-tank with combustion greenhouse gas emissions of transportation fuels derived from North American crudes
Download2017-01-01
Di Lullo, Giovanni, Zhang, Hao, Kumar, Amit
Many studies have calculated deterministic point estimates of well-to-combustion (WTC) emissions of transportation fuels from crude oil in an attempt to determine which crude oils have lower or higher emissions. However, there is considerable variation in the published results, resulting in...

This thesis sets out a workflow to quantify uncertainty of the Arrow Deposit, a tabular, vein type, high-grade, basement-hosted, uranium deposit located on NexGen Energy Limited’s 100%-owned Rook I property in northern Saskatchewan. The uncertainty associated with the volume, grade, and density...

Unsaturated Flow Model
2019-06-06
Xiaochuan Tony Zheng, Tony Zheng
The un-saturated flow sub-model is based on a previously developed infiltration-drainage model. This research improves the original model by adding capabilities of handling dynamic boundary conditions and inter-layer overflow mechanisms. Additional validation cases are conducted to build...

Vegetation responses following mountain pine beetle attack in lodgepole pine forests of west-central Alberta
DownloadFall 2018
Natural disturbances are an integral part of forest ecosystems and drive successional change. The boreal forest is adapted to stand-replacing fires, which have different ecological impacts than less severe disturbances, such as insect attacks. In recent years, mountain pine beetle (MPB), a bark...
