One of the main sources of uncertainty in vein type deposits is found in the calculation of the tonnage. The boundary limits often applied to a vein type deposit are calculated from sparse data using deterministic methods that offer no measure of uncertainty. The most common method used to...

Crane lift path planning is time-consuming, prone to errors, and requires the practitioners to have exceptional visualization abilities, in particular, as the construction site is congested and dynamically changing. This research presents a methodology based on robotics motion planning to...

This research describes a semantic-driven framework to facilitate reusability and interoperability of simulation and modeling of construction processes. An immense amount of knowledge of construction processes and simulation modeling is needed to develop construction simulation models. Knowledge...

The problem of low dissolved oxygen (DO) level has been found to be widespread in ice-covered or polluted rivers. This thesis is targeted at providing some fundamental studies on the remediation measure of injecting air/oxygen via existing effluent diffusers to increase river’s DO level, with two...

Cost and schedule integration can improve efficiencies in construction planning and control since they are key constraints in project delivery and closely related. This research provides a framework for cost and schedule integration, and transforms the model to simulation-based planning in which...

Numeric data for earth sciences often represent fractions or percentages of a whole, such as the chemical or mineralogical composition of a rock. The individual components are non-negative and have a constant sum of 100%. Satisfying these constraints at unsampled locations after estimation or...

Partially encased composite columns consist of thin-walled built-up H-shaped steel sections with links welded near the flange tips and concrete cast between the flanges. The use of PEC columns under concentric axial load only was incorporated into the Canadian steel design standard, CAN/CSA...
