Assessment Of The Regionalization Of Precipitation In Two Canadian Climate Regions: A Fuzzy Clustering Approach, Sarah E. Irwin
Assessment Of The Regionalization Of Precipitation In Two Canadian Climate Regions: A Fuzzy Clustering Approach, Sarah E. Irwin
Electronic Thesis and Dissertation Repository
Regional frequency analysis (RFA) is used to obtain reliable estimates of local precipitation events for a variety of applications in water resources engineering. The focus of the presented research is on an initial step of the RFA process; that is the formation of precipitation regions (also referred to as regionalization). The aim of this study is to dissect the regionalization procedure into its individual components that require subjective user input, and to evaluate their respective influences on the results. All assessments are conducted in two of Canada's climate regions; namely the Prairie and Great Lakes-St. Lawrence lowlands. Additionally, a new …

Determination Of Explosive Energy Partition Values In Rock Blasting Through Small-Scale Testing, Joshua Calnan
Theses and Dissertations--Mining Engineering
Blasting is a critical part of most mining operations. The primary function of blasting is to fragment and move rock. For decades, attempts have been made at increasing the efficiency of blasting to reduce costs and increase production. Most of these attempts involve trial and error techniques that focus on changing a single output. These techniques are costly and time consuming and it has been shown that as one output is optimized other outputs move away from their optimum level. To truly optimize a blasting program, the transfer of explosive energy into individual components must be quantified. Explosive energy is …
