M.Ed. / This study is a result of the commitment of the Eastern Cape Technikon to provide training, research and development in skills needed by the communities it serves. The Eastern Cape Technology and Entrepreneurship Centre (ECTEC) was established in association with the Enterprising Edge and Niagara College. Consequently, a curriculum was made available in order to support the small, medium, and micro entrepreneurs (SMMEs) in Butterworth by educating and training them so that they could run their businesses successfully. Some of the issues that have arisen concerning this intervention, included whether an investigation into the educational and training needs of SMMEs had been done, as well as whether the proposed education and training programme would meet the needs of the intended SMME The aim of this research is to identify and describe the educational and training needs of SMMEs in Butterworth, by conducting a needs assessment. This needs assessment attempts to understand and explain what SMMEs perceive to be their educational and training needs. The sample was composed of SMMEs who are registered learners at the ECTEC. Questionnaires as well as semi—structured interviews were used for data collection. The questionnaire items were summarised and presented in the form of tables. The interview data was then analysed by means of a constant comparative method. The findings of this study show that the educational and training needs of SMMEs are related to issues like accessing finance, keeping proper records of transactions and preparation of books of business, namely, the balance sheet, income as well as cash flow statements. SMMEs also need to know how to undertake the marketing function of their businesses so that they can identify and reach their customers. Finally, SMMEs need to know how to prepare and analyse business plans. These needs should, as far as possible, be considered when designing or modifying the education and training programmes of the SMMEs in order to ensure that training addresses these needs. It is hoped that this study will help to make the course relevant, useful and applicable to the SMMEs in Butterworth and those studying at the ECTEC.

International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The drive towards higher accuracy and sampling rates has raised the bar for modern FTI signal conditioning. This paper focuses on the issue of anti-alias filtering. Today's 16-bit (and greater resolution) ADC’s, coupled with the drive for optimum sampling rates, means that filters have to be more accurate and yet more flexible than ever before. However, in order to take full advantage of these advances, it is important to understand the trade-offs involved and to correctly specify the system filtering requirements. Trade-offs focus on: • Analog vs. Digital signal conditioning • FIR vs. IIR Digital Filters • Signal bandwidth vs. Sampling rate • Coherency issues such as filter phase distortion vs. delay This paper will discuss each of these aspects. In particular, it will focus on some of the advantages of digital filtering various analog filter techniques. This paper will also look at some ideas for specifying filter cut-off and characteristics.

Ultrasonic anemometer (UA) is a core application in natural environment measurement. As well known, mechanical anemometer works well in good weather but it is not suitable to be applied in bad environment such as polar region and upper air. On the other hand, ultrasonic anemometer works well in most situations. Moreover, ultrasonic anemometer has wider detectable wind speed range. It can be said that ultrasonic anemometer is a more advanced instrument to measure wind velocity. In this paper, the theory of ultrasonic anemometer is first discussed. Using the theory, a test bed is then designed and constructed to measure one-dimensional wind speed. Active Butterworth filter is introduced into the circuit in order to increase the stability and accuracy. Furthermore, we test the one-dimensional ultrasonic anemometer and compare the measured wind speed with theoretical wind speed measured by a thermal anemometer device. Error is also discussed and improvement has also made during the experiment.

The research focuses on how teachers can use school gardens sponsored by South African National Biodiversity Institute as resource materials for teaching and learning. The study also focused on how teachers can integrate local knowledge into the school curriculum. The setting of the research is Zizamele Senior Primary School situated in Zizamele community in Butterworth in the Eastern Cape. The study is designed in portfolio format. It consists of three separate studies: a contextual profile; a stakeholder analysis; and a small-scale action research project, which build on each other. By developing a contextual profile of the research site, and the school community and school gardens project, I was able to collect information that informed the stakeholder analysis and the action research study. Data for the contextual profile was gathered by using a variety of data gathering techniques like questionnaires and interviews. The findings were that: the study area is characterized by socio-economic issues like poverty, unemployment, drug abuse and crime. This requires that the people of the area take responsibility in addressing some of the problems by being involved and knowing where to report issues. The second study, which is the stakeholder analysis, was done to mobilize stakeholders’ contributions to the gardens project in Zizamele School, sponsored by the South African National Biodiversity Institute. Data was collected at meetings and workshops in the schools through interviews. Findings indicated that different stakeholders had various contributions to make and that they were prepared to work with the school and with each other to develop the school garden and the learning potential of the school garden. This paved the way for the small scale action research case study that would follow. The last study, the small scale action research, was undertaken in the same school, Zizamele School, and focused on investigating ways of integrating local knowledge into the curriculum and how teachers use the gardens as resource for teaching and learning, with reference to Life Orientation Learning Area. Data was collected by interviews, questionnaires and worksheets. The study involved two teachers who worked with me on the action research and Grade 5 and 6 learners, as well as some of the community stakeholders. The main finding of the action researched showed the potential for involving community members in the process of integrating local knowledge as a way of implementing aspects of the Life Orientation curriculum requirements. The three studies link with each other, and show that to start with an action research project, one needs to understand the context, and the roles of different stakeholders, and how they might contribute to the programmes in the school. Findings showed that teachers could use gardens as resource materials for teaching and learning, and that they could bring in local knowledge to the school curriculum.

This study lists and compares insect herbivores of Senecio inaequidens and of Senecio pterophorus around Butterworth by 18 Tables and 38 Figures. The two plant species are widely distributed around Southern Africa. Samples were taken during a month of each of the four main seasons of the year, which in Butterworth did not show much difference in temperature. The two plant species shared generalist insect herbivores most of which were also on other surrounding plant species. The population of most of the herbivores was affected by the seasons while the two plant species were not seasonal, thus the correlation between insect herbivores and the two plant species was not significant. The heavier, and apparently chemically protected species, Senecio pterophorus, accommodated borers and supported a wider variety of but fewer individual insects. Senecio pterophorus could be having more defences but had more serious herbivores. There were no serious insect herbivores that could control the abundance of the two plant species around Butterworth. Anatomical differences between S. pterophorus and S. inaequidens could be highlighted by the kind and number of insect herbivores found upon them. Similarities were more difficult to identify through studying their insect herbivores. The biology of one serious weed, Lixus sp., on Senecio pterophorus was studied in more detail. The life cycle of the weevil was found to be synchronised with that of the host. This weevil shared the stems with other species of weevils with no indication of competition.

Thesis (MScMedSc)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: This was an investigation into the needs of people with physical disabilities in the district of Butterworth, and their accessibility to available resources, conducted with the aim of improving service delivery in the area. As a physiotherapist the researcher has always been in close contact with people with physical disabilities, and could see the problems they had. The researcher then embarked on conducting this study with the aim of helping them. The study was conducted in three areas, a rural area called Zangwa Administrative Area, Bika, a township, and Skiti, an informal settlement. The research methodology used was qualitative research. Participants in this research included people with physical disabilities, caregivers of people with physical disabilities, and service providers dealing with people with physical disabilities in the district of Butterworth. Methods of data collection used were focus group interviews for people with physical disabilities and caregivers, and questionnaires for service providers. The reason why service providers were given questionnaires, and not interviewed in focus groups, was that they were from different government departments and it was not possible for them to be part of a focus group due to the commitments they had. Questions in the questionnaires and in the interview schedules used in the focus group interviews were similar to each other, and were open ended. A total of 24 people with physical disabilities were recruited to take part in the focus group interviews in identified locations. Nine caregivers of people with physical disabilities, drawn from two of the above locations participated in this study. Focus group interviews were tape recorded, with the informed consents of the participants. The response rate to the questionnaires was 81%: 13 of the 16 service providers returned completed forms. Data analysis was done through a process of listening to the tapes, together with other students, to ensure the trustworthiness of the data, taking detailed notes, translating the interviews from Xhosa to English, coding the data and putting them into categories, with similar categories building up into themes. In the case of the questionnaires, similar responses were grouped together, and those showing the same responses from participants were prioritised. The results of the research indicated that the primary needs of people with physical disabilities were housing, employment, skills‟ development - emphasising training in those skills which could bring them an income - assistance with income generating projects, suitable public transport, accessibility of buildings and facilities, driving schools catering for people with physical disabilities, and Primary Health Care. They needed Primary Health Care to not only address their basic health needs, but to include preventative care, the promotion of effective care, curative and rehabilitative care. At a personal level they required disability grants, caregivers, intimate relationships and marriage. While caregivers placed greater emphasis on assistive devices and Day Care Centres to give them some respite time, service providers emphasised on education for children with disabilities, which neither people with physical disabilities nor caregivers had mentioned. The service providers also said nothing about the need for caregivers and housing. These disparities in the needs mentioned by these three groups of participants showed that needs that may seem important to professionals and other service providers, may not be important to people with disabilities, therefore it is important to consult with the consumers first, before planning for service delivery. It was clear that services were not easily accessible, due to transport and financial problems, as travelling for people with physical disabilities meant additional expenses in terms of hiring special vehicles. Another barrier to accessing resources was lack of knowledge about the availability of those resources, and how they could be accessed. On the basis of this study, recommendations have been made to relevant service providers for the planning and improvement of service delivery. These include more accessible buildings, good roads, and the appointment of suitable individuals to fill vacant posts in different government departments so as to be able to reach all people with physical disabilities in the district of Butterworth. Finally, the researcher emphasizes the need for outreach programmes to raise awareness about available services. / AFRIKAANSE OPSOMMING: Hierdie ondersoek ten opsigte van die behoeftes van mense met fisiese gestremdhede in die Butterworth distrik en hul toegang tot die beskikbare hulpbronne is gedoen met die oog daarop om dienslewering in die omgewing te verbeter. Die navorser het die studie in drie areas naamlik: Zangwa Administratiewe Area,`n landelike gebied, Bika, „n dorp en Skiti, „n informele nedersetting gedoen. Kwalitatiewe navorsingsmetodes is gebruik. Studie deelnemers het bestaan uit mense met fisiese gestremdhede, versorgers van mense met fisiese gestremdhede en diensverskaffers aan mense met fisiese gestremdhede in die Butterworth distrik. Fokus groep besprekings met mense met fisiese gestremdhede en hulle versorgers is gebruik om data in te samel. Voorts is data verkry vanaf vraelyste wat deur diensverskaffers voltooi is. Vier en twintig persone met fisiese gestremdhede, uit bogenoemde drie areas, is geselekteer om aan die fokusgroep besprekings deel te neem. Nege versorgers van persone met fisiese gestremdhede, uit twee van bogedoemde areas, het ook aan die studie deelgeneem. Fokusgroep besprekings is op band opgeneem, met die toestemming van die deelnemers. Dertien van die sestien diensverskaffers (81%) het voltooide vraelyste ingehandig. Volgens die resultate het persone met fisiese gestremdhede `n behoefte aan behuising, werk, vaardigheidsontwikkeling, projekte wat inkomste genereer, geskikte openbare vervoer, toegang tot geboue en fasiliteite, bestuurskole wat voorsiening maak vir mense met fisiese gestremdhede en primêre gesondheidsorg. Die volgende persoonlike behoeftes is geidentifiseer: ongeskiktheidstoelae, versorgers, intieme verhoudings en huwelike. Die versorgers het meer klem geplaas op hulpmiddels en dagsorgsentrums. Die behoefte aan dagsorgsentrums kan aanduidend wees daarvan dat versorgings verligting van die sorg las nodig het.. Diensverskaffers het op hulle beurt klem gelê op `n behoefgte aan onderwys vir kinders met gestremdhede. Dit is nie deur of persone met fisiese gestremdhede of versorgers genoem nie. Die diensverskaffers het niks oor versorgers gesê nie. Die verskille tussen die behoeftes wat deur die drie groepe deelnemers uitgelig is dui daarop dat behoeftes wat as belangrik voorkom vir proffesionele persone en ander diensverskaffers nie noodwendig belangrik is vir mense met gestremdhede nie. Dit is dus belangrik om eers die klient te raadpleeg voordat dienslewering beplan word. Vervoer en finansiele probleme het daartoe gelei dat dienste ontoeganklik was. Vervoer vir mense met fisiese gestremdhede bring addisionele onkostes mee omdat `n spesiale voertuig gehuur moet word. „n Verdere struikelblok met betrekking tot toegang tot hulpbronne was `n gebrek aan kennis oor die beskikbaarheid van hulpbronne in die studie area. Aanbevelings na aanleiding van die studie sluit in: groter toeganklikheid tot geboue, goeie paaie en die aanstelling van geskikte individue om vakante poste in die verskillende staatsdepartemente te vul om sodoende die mense met fisiese gestremdhede in die Butterworth distrik te bedien. Ten slotte, wil die navorser klem lê op die behoefte aan uitreikprogramme om mense bewus te maak van beskikbare dienste.

Neste trabalho se apresenta o desenvolvimento de algoritmos hermitianos de integração das equações diferenciais do filtro digital de Butterworth mediante operadores de integração numérica de ordem elevada com passo único. A teoria do filtro de Butterworth é apresentada mediante o emprego da transformada de Fourier. Exemplos de aplicação apresentados através destes algoritmos mostram que os resultados são, como esperado, mais precisos que os resultantes dos métodos usuais presentes na literatura especializada / In this work is presented the development of hermitian algorithm for integration of the Butterworth digital filter’s differential equations by means of high order numerical one step operators. The Butterworth filter’s theory is presented based on the Fourier transform. Numerical examples show that the results of the developed hermitian algorithm are more accurate than the usual methods present in the specialized literature, as expected

In recent times much attention has b een focussed on the spatial development of countries, especially in those countries of the world referred to as the Third World. Many factors have given rise to this interest. It has arisen due in part to the important position of development today both as a means of enhancing the wealth of man's environment, and as a means of raising living standards. It is also a result of the problems being experienced by many countries due to the large spatial inequalities in development that has arisen in these countries. In Transkei a history of racial discrimination and the impact of its close relationship to its former colonial power, South Africa, have combined to produce a spatial pattern of development in which inequalities have become evident. Unfortunately, meaningful efforts have not been evolved to manage the inequalities in such a way as to achieve a balance in spatial development. The need therefore exists to study the factors causing variations in spatial development in Transkei and to suggest methods through which the evolving pattern can be adapted to conform to, if a balance in spatial development is to be obtained from the present pattern of inequalities. Arising from the background given, this study set out within the growth pole framework to examine the linkages between Butterworth, the most industrial region in Transkei and the rest of the space economy. Forty nine industries and a total of 645 industrial employees of various categories were selected for the study. Linkages were measured with respect to sources of raw materials, destination of finished goods, origin of industrial employees and the destinations of remittances by industrial employees. Through the use of techniques such as percentage concentration, correlations, and regression analysis among others for the analysis of the data, the following information emerged from the study: (i) agglomeration economies for the industries in Butterworth are minimal. (ii) Linkages between Butterworth industries and the rest of the Transkeian space economy are minimal. The minimal agglomeration economies and linkages have been due to the fact that industries are set up in Butterworth neither because a market exist for its products nor that raw materials exist that are to be utilised in production. This implies that industrial developments as at present is not being properly guided to ensure the attainment of a balanced spatial pattern of development. From the above findings, it has been proposed that programmes geared towards the establishment of linkages such as the production of raw materials for the industries will be more beneficial than the present regional development strategy. The need for support measures for the industries in Butterworth has also been proposed as a method of raising their economic efficiency and hence their ability to transmit developmental impulses to other regions in Transkei. / Thesis (M.A.)-University of Natal, Durban, 1991.
