Abstract:
Asian options, also known as average value options, are exotic options whose payoffs are dependent on the average prices of the underlying assets over the life of the options. The Asian options are very popular among the market participants when dealing with thinly traded commodities because the average property of the Asian options makes it very difficult to manipulate the payoffs of the options. Another reason for the popularity of Asian options is that they are cheaper than the corresponding portfolio of standard options to hedge the same exposure. The pricing of Asian options has been the

Abstract:
A Feature Oriented Detail Design System (FODDS2) is described that allows design of 2½ D components. The geometric reasoning required to generate anteriority constraints for subsequent process planning is described with accompanying problems, experiments and proposed solutions. The geometric algorithms currently unavailable in commercial solid modellers, but required for the system are described along with their implementations. All features in the system are described in a consistent manner in terms of a 'tool profile' and 'cutter path' allowing new features to be added simply and easily and

Thesis (MScEng (Process Engineering))--University of Stellenbosch, 2010.<br>ENGLISH ABSTRACT: In a floating medium filter, polymeric beads with a density less than that of water form a floating bed which removes suspended material. Polyolefinic beads (polypropylene and polyethylene) are commonly used as filter media in this application. The geometric properties of the beads, and to a lesser extent the surface properties, strongly influence the performance of the filter. In the case of water treatment, the primary performance requirement is the production of a filtrate with turbidity ≤ 1.0

Abstract:
Islamic design is a rich art form with spiritual and meditative meaning expressed through its infinite pattern. The iterative process of creating pattern, unified yet diverse, is an intri-cate geometric path conveying conceptual exploration. Process of form development in Is-lamic patterns defines its growing design, seeking explicit relationships between unity and multiplicity. As the grid expands and patterns unfold, new concepts are introduced for pat-tern exploration and formation. Reoccurring focal points of the Islamic geometries mark significant moments in which these patterns take form

Abstract:
An ergonomically designed work environment may decrease work related musculoskeletal disorders, lead to less sick leaves and increase production time for operators and companies all around the world. Volvo Construction Equipment wants to deepen the knowledge and investigate more carefully how operators are actually sitting whilst operating the machines, how this affects placement of controls and furthermore optimize controls placements accordingly. The purpose is to enhance their product development process by suggesting guidelines for control placement with improved ergonomics based on operat

Abstract:
As robotic systems move from well-controlled settings to increasingly unstructured environments, they are required to operate in highly dynamic and cluttered scenarios. Finding an object, estimating its pose, and tracking its pose over time within such scenarios are challenging problems. Although various approaches have been developed to tackle these problems, the scope of objects addressed and the robustness of solutions remain limited. In this thesis, we target a robust object perception using visual sensory information, which spans from the traditional monocular camera to the more recently

Abstract:
O tempo de ciclo da usinagem por hidroerosão aumenta após longos períodos de uso do fluido erosivo sem renovação de partículas, o que caracteriza uma redução da eficiência do processo. Esta redução pode ser avaliada por alterações das fases sólida e líquida que compõem o fluido erosivo. Neste trabalho os indicadores de eficiência do processo foram obtidos para um período de 150 horas de usinagem para arredondamento da seção de entrada de canais internos de bicos injetores, sem renovação de partículas. Para este intervalo foram determinadas as distribuições de tamanho das partículas de B4C, con
