41	Designing a geodetic research data management system for the Hartebeeshoek radio astronomy observatory Coetzer, Glenda Lorraine 11 1900 (has links) The radio astronomy and space geodesy scientific instrumentation of the Hartebeesthoek Radio Astronomy Observatory (HartRAO) in Gauteng, South Africa, generate large volumes of data. Additional large data volumes will be generated by new geodesy instruments that are currently under construction and implementation, including a lunar laser ranging (LLR) system, seismic and meteorological systems and a Very Long Baseline Interferometry (VLBI) global observing system (VGOS) radio telescope. The existing HartRAO data management and storage system is outdated, incompatible and has limited storage capacity. This necessitates the design of a new geodetic research data management system (GRDMS). The focus of this dissertation is on providing a contextual framework for the design of the new system, including criteria, characteristics, components, an infrastructure architectural model and data structuring and organisation. An exploratory research methodology and qualitative research techniques were applied. Results attained from interviews conducted and literature consulted indicates a gap in the literature regarding the design of a data management system, specifically for geodetic data generated by HartRAO instrumentation. This necessitates the development of a conceptual framework for the design of a new GRDMS. Results are in alignment with the achievement of the research questions and objectives set for this study. / Information Science / M.A. (Information Science) Conceptual /architectural model Data life-cycle Data management systems Scientific data management systems Data structuring Digital object identifiers (DOIs) File naming conventions (FNCs) Geodetic data Metadata 025.04028565

43	Shaft No.2 : re-scripting the future of Johannesburg's third landscapes through architecture of the terrain vague Watkins, Dylan 26 March 2014 (has links) M.Tech. (Architectural Technology) / Johannesburg has a spacial condition of an infill city which has created a condition of ‘non place’, allowing for forgotten beauties within this disjunct urban fabric. In the author’s opinion, this condition of ‘non place’ allows for new exciting opportunities to connect this isolated landscape with its urban surrounds, manifesting a new urban layer. It is within this urban archipelago that an architectural intervention will be realised. Commenting on the hypotheses, the architecture should become a space within which nature can grow and become part of systemic exchange, creating a new urban ecology. When architecture and nature are fused, a new hybrid emerges, re-scripting the site of terrain vague into catalyst for socio ecological remediation. The architecture will not only attempt to rescript the third landscape, but also become a platform for exchange where knowledge can be obtained and shared through the tracing and recording of the landscape and climate influence. This dissertation explores architecture in a manner which will incorporate nature and remediation as a generator of the architecture of the terrain vague. By introducing biometics and technology, the architecture becomes an instrument of the site, in this way the architecture will respond to site and climate conditions, resulting in a systemic symbioses with nature. The architecture will respond to environmental conditions; expanding, contracting, moving and adapting, creating a different experience for the user on a daily basis.
