D. Tech. Engineering: Electrical. / The remarkable evolution of wireless networks into the next generation to provide ubiquitous and seamless broadband applications has recently triggered the emergence of Wireless Mesh Networks (WMNs). The WMNs comprise stationary Wireless Mesh Routers (WMRs) forming Wireless Backbone Mesh Networks (WBMNs) and mobile Wireless Mesh Clients (WMCs) forming the WMN access. While WMCs are limited in function and radio resources, the WMRs are expected to support heavy duty applications: that is, WMRs have gateway and bridge functions to integrate WMNs with other networks such as the Internet, cellular, IEEE 802.11, IEEE 802.15, IEEE 802.16, sensor networks, et cetera. Consequently, WMRs are constructed from fast switching radios or multiple radio devices operating on multiple frequency channels. WMRs are expected to be self-organized, self-configured and constitute a reliable and robust WBMN which needs to sustain high traffic volumes and long "online" time. However, meeting such stringent service expectations requires the development of decentralized dynamic transmission power control (DTPC) approaches. This thesis addresses the DTPC problem for both single and multiple channel WBMNs. For single channel networks, the problem is formulated as the minimization of both the link-centric and network-centric convex cost function. For multi-radio multichannel (MRMC) WBMNs, the network is modelled as sets of unified channel graphs (UCGs), each consisting of interconnected active network users communicating on the same frequency channel.

D. Tech. Chemical Engineering / Objectives of the study is to optimize the production of biodiesel from non-edible oils using both homogeneous and heterogeneous catalysts.

M. Tech. Mathematical Technology / Makes use of a linear PDE with a known analytical solution and solve it using the NDSolve built in Mathematica function. NMOL will be used directly on the same problem and then Joubert, Greeff and Fays error analysis will be implemented. The results obtained from this error analysis technique will be compared with the known conventional approach which uses the analytical solution. In this way, appropriate conclusions can be drawn about the accuracy of NMOL.

M. Tech. Engineering: Electrical. / Discusses the purpose of the study to develop a MFC scheme that can adapt and adjust to the changing workspace to enhance WMR operations.

M. Tech. Electronic Engineering. / Explores and compare geospatial techniques to improve the detection and classification of settlement types in QuickBird and SPOT 5 satellite images for the purpose of better environmental assessment and monitoring.

M. Tech. Food Technology. / Flaxseed oilcake as produced by a South African local Oil Mill has not been used directly in human food. The research problem was to evaluate the local flaxseed oilcake for its chemical and microbiological quality and shelf-life. Its suitability for incorporation into bread was investigated. Methods and procedures used included proximate analysis, determinations for total dietary fibre, fatty acid profile, mineral composition and water activity (aw); shelf-life studies and microbiological testing for spoilage micro-organisms and possible pathogenic bacteria. The effect of flaxseed oilcake inclusion in brown bread on the sensory quality of the bread was determined using a trained sensory panel and a consumer panel. A texture analyzer was used to measure the staling of the products. The main findings were that the flaxseed oilcake was high in protein and dietary fibre. The oil was rich in alpha linolenic acid. Toxic mineral content was such that it should be safe at suggested inclusion levels. The oilcake had a low microbial count and no pathogenic bacteria were found. The shelf-life study showed the oil to be relatively stable. Sensory analyses revealed that an 11% inclusion level of oilcake in brown bread was acceptable. In conclusion, it can be recommended that the locally produced oilcake is suitable for use in food and an 11% inclusion level will be safe and acceptable with nutritional benefits to the consumer.

M. Tech. Biomedical Technology. / Aims to determine whether pure type collagen biomaterial gels can be protected from scission damage by the addition of different fractions from ColBio, resulting in successful cross-linking by g-irradiation.

M. Tech. Business Administration / The aim of the study is to determine the influence of the implementation of job rotation on employees perceived job satisfaction and to identifiy the key factors that would influence the adoption of a job rotation strategy by the Registrar's environment of the Tshwane University of Technology.

D. Tech. Education / The research study sought to find out if social studies textbooks used at stage 4 level in Zimbabwean primary school are deficient in content. The focus was on the relevance and adequacy of the content to meet National Curriculum Standards.

M. Tech. Education / The study was aimed at finding out the reasons why Grade 9 learners lack interest in studying Accounting in the General Education and Training (GET) band, at selected Soshanguve schools in Tshwane North District (D3). Kunene (2008:3) asserts that teaching the subject Accounting should equip learners with the knowledge and skill they need to cope with the demands of the workplace and the pace of change in the real world. Bloch (2012:1) shares the view that teachers should be in the front line and have to lead the new liberation struggle of knowledge and skills for economic and social cohesion.
