Thesis (MTech. degree in Architecture: Professional)--Tshwane University of Technology, 2011. / This design dissertation will deal with the making of a gateway or portal in order to improve the imageability of the campus. It is thus based on the upgrading and integration of the existing Metro Rail Station and the design of a student centre on the Pretoria Campus in order to become a social interactive arrival space serving the people of the institution. The architectural intervention is based on the principle of a gateway, that illustrates a notable transition when entering the campus. The concept of a horizontal timeline is adapted that is symbolic of the advancement of technological development of the knowledge and skills generated by the university.

<p>The aim of the research project is to investigate the effectiveness of an information literacy intervention for first year engineering students at the Cape Peninsula University of Technology. Information literacy has been identified as a necessary outcome of tertiary education. It refers to the life-long learning competencies of finding and using information in order to solve problems, to make decisions and to create new knowledge. Information literacy education has evolved from earlier forms of library user education, such as bibliographic instruction, and is central to the mission of academic libraries. However, librarians responsible for information literacy programmes seldom evaluate the effectiveness of their interventions. In today&rsquo / s climate of accountability and outcomes-based education, it is necessary to provide evidence of the benefits of the user education that libraries provide. The researcher uses the American College and Research Library (ACRL) Information Literacy Competency Standards for Higher Education, which are internationally recognized and widely used by South African academic librarians, as a benchmark to evaluate an intervention for a group of first year students enrolled for a mechanical engineering course. The intervention consists of two workshops which aim to teach the students to find information relevant to their essays via the university&rsquo / s OPAC, various engineering databases and to teach them how to reference and cite their sources in their essays. The research methodology assessed students&rsquo / information literacy before and after the two workshops with the use of a questionnaire consisting of a set of questions based on some of the ACRL standards. The questionnaire also gathered data on students&rsquo / prior experience of libraries, reading and computers, which might impact on their information literacy...</p>

Thesis (MPhil)--Stellenbosch University, 2008. / ENGLISH ABSTRACT: This study takes as starting point the observation in sensemaking theory that autonomic arousal is accompanied by a loss of existing frames and cues and the consequential cognitive implosion. Situations such as these are marked by a crisis in identity construction and the resultant loss of sense being made. The aim of the study was to find out to what extent this phenomenon is at play during a merger between two organizations. Specifically to what extent this phenomenon did manifest itself among the employees of the Central University of Technology in Welkom after the merger of the former Welkom Campus of Vista University and the Technikon Free State. The study starts with an overview of the literature on corporate mergers; focusing on research on effects with regards to (i) how the different gender groups of employees were affected by these interruptions, (ii) how employees with diverse levels of experience were affected, (iii) to what extent the qualifications of employees was a factor regarding the impact of this autonomic arousal and (iv) whether race was a factor in determining the extent of autonomic arousal. The above is followed by an explanation of the sensemaking perspective and the nature of and moment for autonomic arousal. It is argued that organizational mergers represent an interruption in the ongoing flow of sensemaking that could lead to autonomic arousal. Using sensemaking theory and autonomic arousal as a theoretical starting point, interviews were conducted with key figures in the specific merger between the Vista University Welkom Campus and the Technikon Free State. The respondents were selected using the snowballing sampling technique. The idea behind the interviews was to demonstrate how staff members were emotionally affected by the interruption of the merger and how it had an impact on their perceptions about their work. It was found that the flow of experience was interrupted and as cues and frames were reduced, the employees focussed more on personal issues. / AFRIKAANSE OPSOMMING: Hierdie studie neem as vertrekpunt die observasie van singewingsteorie dat outonomiese aktivering gepaard gaan met 'n verlies aan bestaande raamwerke en aanduidings en die gevolglike kognitiewe implosie. Sulke situasies word gekenmerk deur 'n krisis in identiteitskonstruksie en gevolglike verlies aan sin. Die doel van hierdie studie was om uit te vind tot watter mate hierdie fenomeen plaasvind tydens 'n samesmelting van organisasies, en spesifiek hoe dit manifesteer onder die werknemers van die Sentrale Universiteit van Tegnologie in Welkom na die samesmelting van die Welkom-kampus van Vista Universiteit en die Technikon Vrystaat. Die studie begin met 'n oorsig van die literatuur oor korporatiewe samesmeltings en oomames, spesifiek oor daardie studies wat die effekte bestudeer met betrekking tot (i) hoe verskillend mans en vroue geraak is, (ii) die impak van verskillende vlakke van ervaring onder werknemers se persepsies oor die samesmelting, (iii) die mate waartoe die kwalifikasievlak van werknemers, asook (iv) ras 'n rol gespeel het in die vlak van outonomiese aktivering wat deur werknemers ervaar is. Daama word singewingsteorie en die aard en geleenthede van outonomiese aktivering uitgepak. Daar word argumenteer dat korporatiewe samesmelting 'n onderbreking in die vloei van sin veroorsaak wat tot outonomiese aktivering kan lei. Ge1ei deur singewingsteorie en outonomiese aktivering as teoretiese vertrekpunt is onderhoude gevoer met sleutelfigure in die spesifieke samesmelting tussen die Welkom kampus van Vista Universiteit en die Technikon Vrystaat om die outonomiese effek van die onderbreking te illustreer. Die respondente is deur die sneeubalmetode geselekteer. Die idee is om te toon hoe werknemers emosioneel getref is en hoedat dit 'n impak op hulle persepsies rondom hulle werk tot gevolg gehad het. Daar is bevind dat die vloei van sin deur die samesmelting onderbreek is, en dat werknemers soos te wagte, meer op persoonlik sake begin fokus. Dit dui op 'n vemouing van singewingsraamwerke en die verlies van lewensin.

This research is an investigation of the potential means to make the Information Systems (IS) course more accessible to Walter Sisulu University (WSU) students. As some IS students at this institution are unable to attend classes on a regular basis, this study aims to establish if and how the WSU Accounting Department (which offers the IS course) could use e-Iearning to support the teaching, learning and assessment of IS. This qualitative study was approached from an interpretive perspective. The study has undergone one cycle of an action research approach. The methods used in the study include surveys, an expert review and focus group interviews. The data was elicited from participants using questionnaires and an interview schedule. A staff questionnaire was used to elicit information from IS staff from four contact universities in South Africa to determine their experience of using Information and Communication Technology (ICT) for e-learning in an IS course. A student questionnaire was used to determine the WSU IS students' reasons for absenteeism, their learning needs, and their current computer access and skills. Data from both of these surveys informed the development of the WSU IS pilot website. An expert review questionnaire ascertained the subject expert's opinions about the newly developed WSU IS pilot website. The website was found to be of good quality with respect to the four aspects that Harvey and Green (J 993 cited in Lomas 2002) use to define quality. Some modifications were made to the WSU IS pilot website as a result of the expert's comments. After the website was used by the IS students, two focus group interviews were conducted to determine the students' perceptions of the value of the website. The data was analyzed, interpreted and linked to the literature surveyed. The main findings indicate that the WSU IS pilot website could be part of a more globalised higher education offering than the paper-based IS course offered before. However, the staff and the student surveys revealed that ICT has opened the gap in equity at the higher education institutions, highlighting that access to a university does not mean equal access to lectures and computers. The WSU IS pilot website endeavoured to capitalise on students' physical access to computers by supporting epistemological access to the curriculum, by encouraging them to exercise control over their learning. This study has ideally enabled the Accounting Department to deliver its services to students and this in turn will hopefully help WSU retain its part-time students and improve the student pass rates.

Thesis submitted in fulfilment of the requirements for the degree Master of Technology: Civil Engineering in the Faculty of Engineering at the CAPE PENINSULA UNIVERSITY OF TECHNOLOGY 2014 / The current problems of orifice, nozzle and Venturi flow meters are that they are limited to turbulent flow and the permanent pressure drop produced in the pipeline. To improve these inadequacies, converging-diverging (C-D) tubes were manufactured, consisting of symmetrical converging and diverging cones, where the throat is the annular section between the two cones, with various angles and diameter ratios to improve the permanent pressure loss and flow measurement range. The objective of this study was firstly to evaluate the permanent pressure loss, secondly to determine the discharge coefficient values for various C-D tubes and compare them with the existing differential pressure flow meter using Newtonian and non-Newtonian fluids, and finally to assess the performance of these differential pressure flow meters. The tests were conducted on the multipurpose test rig in the slurry laboratory at the Cape Peninsula University of Technology. Newtonian and non-Newtonian fluids were used to conduct experiments in five different C-D tube flow meters with diameter ratios (β) of 0.5, 0.6 and 0.7, and with angles of the wall to the axis of the tube (θ) of 15°, 30° and 45°. The results for each test are presented firstly in the form of static pressure at different flow rates. It was observed that the permanent pressure loss decreases with the flow rate and the length of the C-D tube. Secondly, the results are presented in terms of discharge coefficient versus Reynolds number. It was found that the Cd values at 15° drop earlier than at 30° and 45°; when viscous forces become predominant, the Cd increases with increasing beta ratio. The Cd was found to be independent of the Reynolds number for Re>2000 and also a function of angle and beta ratio. Preamble Performance of a symmetrical converging-diverging tube differential pressure flow meter Finally, the error analyses of discharge coefficients were assessed to determine the performance criteria. The standard variation was found to increase when the Reynolds number decreases. The average discharge coefficient values and their uncertainties were determined to select the most promising C-D tube geometry. An average Cd of 0.96, with an uncertainty of ±0.5 % for a range of Reynolds numbers greater than 2,000 was found. The comparison between C-D tubes 0.6(15-15) and classical Venturi flow meters reveals that C-D 0.6(15-15) performs well in turbulent range and shows only a slight inaccuracy in laminar. This thesis provides a simple geometrical differential pressure flow meter with a constant Cd value over a Reynolds number range of 2000 to 150 000.

Submitted to the Department of Electrical Engineering in Fulfilment of the Requirements for the Magister Technologiae in Electrical Engineering at the Cape Peninsula University of Technology SUPERVISOR: E. VOSS NOVEMBER 2013 / The reluctance synchronous machine (RSM) operates on the principle of magnetic reluctance, which is produced through a careful selection of rotor flux barriers and cut-outs. Magnetic reluctivity is the resistance to magnetic flux and can be directly related to the principles of Ohm’s law in electrical circuits. Although reluctance motors have been known for more than 150 years, researchers lost interest when Nikola Tesla’s induction machine (IM) was introduced to industry. Over the last few decades, however, RSMs have shown a lot of potential. They are cheap, robust, reliable, and their rotors can also be used in the stators of IMs. The disadvantage of these machines is an inherently high torque ripple, being the result of its rotor geometry, but the biggest advantage is having a significant reduction in copper losses after the rotor cage has been removed. This advantage drove engineers to investigate, optimise and modify the performance and structure of this machine, which led to the usage of electronic drive systems. The recent advances in technology have allowed researchers to further investigate and modify the design and performance of this special type of machine, with the integration of Finite Element Analysis (FEA) software also making a contribution to the development of the RSM’s current driven systems. The voltage-fed RSM, driven direct-on-line (DOL) from the utility supply, was left in the shadows as the current-fed RSM took reign, but still is, in the author’s opinion, not yet fully analysed. This thesis practically investigates the performance characteristics of the cageless, voltage-fed 3kW RSM in its steady-state operation, under various loads. These performance characteristics are also compared to a RSM driven from a sensorless vector drive (current-fed) to investigate the advantages and disadvantages between the two. Experiments performed on the test bench immediately reveal a limitation to the voltage-fed RSM’s ability to drive higher loads. While the current-fed RSM conveniently reaches 150% of its full-load, the voltage-fed RSM, due to its cageless structure, only reaches 110% of its full-load power. Despite this discovery, the voltage-fed RSM proves to have a lower core loss, harmonic content and torque ripple. Using a FE software package with an integrated source-code, additional parameters such as the dq-axis inductances and currents are also compared and analysed in terms of its reaction to an increase in load. The eddy-current, hysteresis and excess losses are also analysed as well as the harmonic components caused by the geometry of the RSM. For academic purposes, a fair amount of emphasis is placed on the approach to the problem. The preparation for the FE simulation is explained in detail, providing insight into the FE mathematical model as well as parameter acquisition. These parameters include current angle, friction and windage losses, stator resistance, end-winding leakage reactance, core loss and inertia. The results obtained by the FE model are compared to that of the measured results and is found to have an error of only 0.52%. Furthermore, this study attempts to find the feasibility of the voltage-fed RSM’s practicality in modern-day industry. The conclusion is drawn that the voltage-fed RSM could be used as a more elegant alternative to an otherwise over-complicated and over-priced installation.

Submitted to the Department of Electrical Engineering in Fulfilment of the Requirements for the Magister Technologiae in Electrical Engineering at the CAPE PENINSULA UNIVERSITY OF TECHNOLOGY SUPERVISOR: E. VOSS NOVEMBER 2013 / Radial and peripheral displacement of stator teeth in electrical machines is known to be the cause of undesired vibration which leads to noise. This thesis serves to investigate the possibility of physically measuring the radial displacement of stator teeth caused by electromagnetic forces which, to the author’s knowledge, has not yet been achieved. A simplified practical approach is adopted in order to address the inherent difficulties attached to this problem, and the measurement of displacement is done by means of an experimental rig where a tooth is subjected to magnetic force acting over an air gap. Three experiments are carried out, each comprising ten tests, the results of which are compared in order to gain some idea as to the magnitudes of displacement which can be expected over a range of applied air gap flux densities. The aim of this work is to observe the displacement response of magnetised EM core material when acted upon by forces, and to see if the measured results agree with the elastic displacement predicted by a wellknown formula. It will be shown that although the measured results are in the same range as the predicted results, there is a deviation from the predicted linearity due to certain characteristics of the force rig, which are explained. The chosen measurement method is capacitive displacement and is shown to be a viable alternative to the more commonly used search coils and vibrometers in past literatures, especially when measuring displacements on the nano-scale. In addition, this study shows the importance of using 3D finite element software to simulate the electromagnetic model when saturation is present in the core of the test specimen. The important findings of this work are discussed in detail, and some ideas put forward, in an attempt to establish a starting point for future related work in the measurement of electromagnetic forceinduced displacement of stator teeth in electrical machines.

Thesis (MTech (Electrical Engineering))--Cape Peninsula University of Technology, 2009 / The purpose of this project is to develop methods for distribution network power quality' variations monitoring. Power quality (PO) has become a significant issue for both power suppliers and customers. There have been important changes in power system regarding to power quality requirements. "Power quality" is the combination at voltage quality and current quality. The main research problem of the project is to investigate the power quality of a distribution network by selection of proper measurement, applying and developing the existing classic and modern signal conditioning methods for power disturbance's parameters extracting and monitoring. The research objectives are: To study the standard lEC 61000-4-30 requirements. to investigate the common couplings in the distribution network. To identity the points for measurement, to develop MySQL database for the data from the measurement and to develop MATLAB software tor simulation of the network To develop methods based on Fourier transforms for estimation of the parameters of the disturbances. To develop software for the methods implementation, The influence of different loads on power quality disturbances are considered in the distribution network. Points on the network and meters according to the lEC power quality standards are investigated and applied for the CPUT Bellville campus distribution network. The implementation of the power quality monitoring for the CPUT Bellville campus helps the quality of power supply to be improved and the used power to be reduced. MATLAB programs to communicate with the database and calculate the disturbances and power quality parameters are developed.
