Understanding the global pattern of glaciation can aid interpretation of what caused late-Pleistocene glacial cycles. Here I investigate the glacial history of the Khumbu Glacier of the Mount Everest region of Nepal. Prominent hypotheses for Himalayan glaciation suggest importan…

Given the amount of electrical consumption associated with living in contemporary society, renewable energy technologies that offer a distributed and cost effective means of generating electricity need to be further developed and researched. Small wind turbines have the capacity…
This thesis presents investigations into the effect of modern wind farms on grid side short circuits using extensive real time digital simulation. Particular reference is made to adaptive autoreclosing algorithms using artificial neural networks. A section of 132kV transmission …
Power system islanding is gaining increasing interest as a way to maintain power supply continuity. However, before this operation become viable, the technical challenges associated with its operation must first be addressed. A possible solution to one of these challenges, out-o…
The purpose of this thesis is to investigate the loadings on and motion of an offshore wind turbine. The three major components of an offshore wind turbine are the wind turbine, the platform and the mooring lines. The effects of these components on the motion of the wind turbine…
Reliability is the probability that a system or component will satisfactorily perform its intended function under given operating conditions. The average time of satisfactory operation of a system is called the mean time between failures (MTBF) and. the higher value of MTBF indi…
Hurricanes and tropical cyclones, in general, are of great interest to weather and climate scientists alike due to their destructive tendency. Though Hawaii has historically avoided being hit directly by hurricanes, it is certain that the islands are uniquely vulnerable to cyclo…
The South American Monsoon System (SAMS) is characterized by a well-defined wet and dry season, which is connected to the reversal of anomalous low-level winds east of the Andes. Driven by local and remote processes, the intensity and duration of the SAMS can vary considerably f…
The current practice in wind resistant design in the United States is to proportion and detail the lateral force resisting system to remain elastic, even for extremely-rare large-magnitude windstorms. The objective of this study is to determine the applicability of inelastic des…
Attempts to design public markets in Oman failed to capture the social and cultural essence of historical markets in the region. The versatility of use and utilization of site resources in public markets diminished due to focusing primarily on the commercial aspect and the utili…
The oceanic uptake of atmospheric CO2 is of global importance as it affects the pace of climate change. The Arctic Ocean acts as a carbon sink for atmospheric CO2, benefiting from high solubility of CO2 in cold seawater and high summer biological production. It has been known th…
