Jacka, David. "High-Level Control of Agent-based Crowds by means of General Constraints." Thesis, University of Cape Town, 2009. http://pubs.cs.uct.ac.za/archive/00000638/.

Abstract:
The use of virtual crowds in visual eects has grown tremendously since the warring armies of virtual orcs and elves were seen in The Lord of the Rings. These crowds are generated by agent-based simulations, where each agent has the ability to reason and act for itself. This autonomy is eective at automatically producing realistic, complex group behaviour but leads to problems in controlling the crowds. Due to interaction between crowd members, the link between the behaviour of the individual and that of the whole crowd is not obvious. The control of a crowd's behaviour is, therefore, time cons

Abstract:
South Africa is currently building MeerKAT, a 64 dish radio telescope array, as a pre-cursor for the proposed Square Kilometre Array (SKA). Both telescopes will be located at a remote site in the Karoo with a low level of Radio Frequency Interference (RFI). It is important to maintain a low level of RFI to ensure that MeerKAT has an unobstructed view of the universe across its bandwidth. The only way to effectively manage the environment is with a record of RFI around the telescope. The RFI management team on the MeerKAT site has multiple tools for monitoring RFI. There is a 7 dish radio teles

Abstract:
Current gas turbine technology for power generation is generally optimised for natural gas. On the basis of current instabilities in natural gas price and supply, the use of alternative fuels, such as syngas, has recently gained high interest. Due to the different thermodynamic properties of syngas compared to natural gas the behaviour of existing gas turbine components may significantly change. From practical and economic points of view, it is generally considered that in order to meet the new fuel properties, the main effort should be put on the adaptation of conventional gas turbines in int

Abstract:
Today, fostering gas-fired power plants is recognised as a significant step towards a low-carbon economy. Gas fired-power plants are favoured over other types of fossil-fuelled power plants due to their various advantages, including lower emissions, flexibility of technology, higher efficiency, short construction times and lower capital investment. The gas turbine is the main machine and the most technologically advanced part of a gas-fired power plant. There have been a limited number of companies in industrialised countries that have developed these sophisticated technologies over the last 5

During the last decades, the study of seismic anisotropy has provided useful information for the interpretation and evaluation of the stress field and active crustal deformation. Seismic anisotropy can yield valuable information on upper crustal structure, fracture field, and presence of fluid-saturated rocks crossed by shear waves. Several studies worldwide demonstrate that seismic anisotropy is related to stress-aligned, filled-fluid micro-cracks (EDA model, Crampin et al., 1984b; Crampin, 1993).

Tsunamis are gravity waves propagating at the ocean surface: they are characterized by wavelengths that may vary from 10 to several hundred of km and by periods from 5 to 45 minutes. Tsunamis are generated, in most cases, by earthquakes that produce large vertical displacement of the ocean bottom and, less frequently, by submarine landslide and by volcanic explosions. The aim of this thesis is to show that tsunami modeling and observation can give complementary information on the tsunamigenic seismic source.
