The statistical modelling of extreme precipitation structures is essential in many aspects such as assessing and managing risks resulting from the occurrence of such extreme events for agricultural purposes, in particular. Typically, daily precipitation time series with many zer…
Determining risk to human populations due to natural disasters has been a topic of interest in the STEM fields for centuries. Earthquakes and the tsunamis they cause are of particular interest due to their repetition cycles. These cycles can last hundreds of years but we have on…
This study examined the role of particular tasks implemented through two instructional methods on college students' achievement and understanding of probability. A mixed methods design that utilized a pre-test and post-test was used. This included treatment and control groups, e…
Although they are both accounts of events, the history and the novel are not commensurate; the novel’s content is usually considered as opposed to that of history. It is assumed that history relates real things whereas the novel excels in dealing with the imagination (fiction). …
The evolution of the concept of "randomness" is explored through the method of historical research. This dissertation examines the use of chance mechanisms through artifacts originating in Mesopotamia, the Indus valley, Egypt, and Babylonia as early as the third millennium B.C. …
This dissertation investigated preservice secondary mathematics teachers' preparation to teach probability and statistics, their confidence in their ability to teach probability and statistics to secondary students, and their understanding of selected probability and statistics …
This dissertation investigates how political instability is related to the probability of civil war. According to the literature in comparative politics, regime breakdown is caused by critical events such as economic decline, defeat in interstate war, death of a leader in office…
Existing methods proposed for estimating the earthquake-induced one-dimensional free-field settlement in saturated soil, focus on the post-liquefaction permanent volumetric strain. These methods rely on undrained cyclic laboratory tests that subject the sandy samples to uniform …
Under similar conditions, products that are designed and used for similar tasks fail similarly. Developers may become aware of various product failure modes during the initial stages of new product generation, where redesign and failure mitigation processes can occur with minima…
The development of a reliable, and cost-effective in-situ method for characterizing the liquefaction potential of gravelly soils is a considerable challenge for engineers and researchers. The ability to accurately characterize the liquefaction potential of gravelly soils is an i…
This thesis develops a topological approach to robustness to incorrect-incomplete models in MDPs and POMDPs, and applications of this study to approximations, model learning and reinforcement learning.
Tunnels are classified as complex engineering structures, which requires careful analysis and design procedures. Any instability of tunnels will be highly detrimental to their performance thereby posing a threat to public safety, consequently cause life-threatening and infrastru…
