Both globally and locally, agriculture faces ever increasing challenges such as high input costs, strict environmental laws, decrease in land for cultivation and an increase in demand due to the growing global population. Profitability and sustainability requires more effective production systems. Precision agriculture is identified as such a system and is built upon a system approach that aims to restructure the total system of agriculture towards low input, high efficiency and sustainable agriculture. The aim of this study was to analyse the state of precision agriculture in the summer grain producing areas of South Africa, specifically the North West and Free State provinces. In order to achieve this, a literature study was conducted. During the literature study the term ‘precision agriculture’ was defined and discussed. The precision agriculture cycle and its components were explained and benefits of precision agriculture were identified. The literature study was concluded with identifying and discussing the most widely used and most beneficial technologies as well as reasons for slow adoption. Findings from the literature study were used to investigate the state of precision agriculture locally. In order to achieve this, a quantitative approach was used and information was collected by means of an empirical study using a questionnaire. Questionnaires were distributed to farmers using selling agents of an agricultural company that is well represented in the targeted areas. The data was then statistically analysed. The survey showed that only 52% of summer grain producing farmers in the North West and Free State provinces of South Africa practises precision agriculture as defined in the v literature study. The study also revealed that the majority of precision agriculture farmers are over the age of 40, have more than 16 years of farming experience, are well educated, cultivate more than 1,000 hectares and uses none or little irrigation. The most commonly used precision agriculture technologies were grid soil sampling and yield monitors. The perception among most of the farmers was that precision technologies are not very affordable, not easily available and that it lacks proper testing with regards to efficiency. The group of summer grain–producing farmers that have correctly implemented precision agriculture as per definition stated that the benefits they derived from precision technologies include reduction in input costs, increased outputs and improved management skills. Too high implementation costs and technologies not providing enough benefits were among the main reasons farmers do not implement precision agriculture. It was concluded that a significant effort and amount of work is needed to increase the use of precision agriculture among summer grain–producing farmers in the targeted areas. A consolidated effort from government, agricultural institutions and agricultural companies will be needed to achieve this goal. Implementing precision agriculture as a system will require education (from primary to tertiary institutions) and improved marketing strategies. Only then will precision technologies be able to help meet the future demands placed on the agriculture sector. / Thesis (M.B.A.)--North-West University, Potchefstroom Campus, 2012.

Atrial fibrillation is a common heart arrhythmia which is characterized by a missing or irregular contraction of the atria. The disease is a risk factor for other more serious diseases and the total medical costs in society are extensive. Therefore it would be beneficial to improve and optimize the prevention and detection of the disease.   Pulse palpation and heart auscultation can facilitate the detection of atrial fibrillation clinically, but the diagnosis is generally confirmed by an ECG examination. Today there are several algorithms that detect atrial fibrillation by analysing an ECG. A common method is to study the heart rate variability (HRV) and by different types of statistical calculations find episodes of atrial fibrillation which deviates from normal sinus rhythm.   Two algorithms for detection of atrial fibrillation have been evaluated in Matlab. One is based on the coefficient of variation and the other uses a logistic regression model. Training and testing of the algorithms were done with data from the Physionet MIT database. Several steps of signal processing were used to remove different types of noise and artefacts before the data could be used.   When testing the algorithms, the CV algorithm performed with a sensitivity of 91,38%, a specificity of 93,93% and accuracy of 92,92%, and the results of the logistic regression algorithm was a sensitivity of 97,23%, specificity of 93,79% and accuracy of 95,39%. The logistic regression algorithm performed better and was chosen for implementation in Java, where it achieved a sensitivity of 97,31%, specificity of 93,47% and accuracy of 95,25%. / Förmaksflimmer är en vanlig hjärtrytmrubbning som kännetecknas av en avsaknad eller oregelbunden kontraktion av förmaken. Sjukdomen är en riskfaktor för andra allvarligare sjukdomar och de totala kostnaderna för samhället är betydande. Det skulle därför vara fördelaktigt att effektivisera och förbättra prevention samt diagnostisering av förmaksflimmer.   Kliniskt diagnostiseras förmaksflimmer med hjälp av till exempel pulspalpation och auskultation av hjärtat, men diagnosen brukar fastställas med en EKG-undersökning. Det finns idag flertalet algoritmer för att detektera arytmin genom att analysera ett EKG. En av de vanligaste metoderna är att undersöka variabiliteten av hjärtrytmen (HRV) och utföra olika sorters statistiska beräkningar som kan upptäcka episoder av förmaksflimmer som avviker från en normal sinusrytm.   I detta projekt har två metoder för att detektera förmaksflimmer utvärderats i Matlab, en baseras på beräkningar av variationskoefficienten och den andra använder sig av logistisk regression. EKG som kommer från databasen Physionet MIT används för att träna och testa modeller av algoritmerna. Innan EKG-signalen kan användas måste den behandlas för att ta bort olika typer av brus och artefakter.   Vid test av algoritmen med variationskoefficienten blev resultatet en sensitivitet på 91,38%, en specificitet på 93,93% och en noggrannhet på 92,92%. För logistisk regression blev sensitiviteten 97,23%, specificiteten 93,79% och noggrannheten 95,39%. Algoritmen med logistisk regression presterade bättre och valdes därför för att implementeras i Java, där uppnåddes en sensitivitet på 91,31%, en specificitet på 93,47% och en noggrannhet på 95,25%.

Bibliography: leaves 207-224 / Abstracts and keywords following the Appendices / This thesis evaluates Ethiopian higher learning institutes’ digital libraries (DLs) for their usability and usefulness. The outcome contributes knowledge by helping to propel development efforts; satisfy DL stakeholders; provide information and fill information gaps; serve as cross-reference for academicians and researchers in the discipline; make decisions and solve managerial issues in DLs of the developing world; and provide scientific interests and merits for the advancement of information systems. When undertaking usability and usefulness evaluation research in DLs, there is no agreed-upon established conceptual framework that guides researchers in the developing world. Therefore, the overall objective of this research is to propose a framework for DL evaluation that fits into the context of developing countries. As the study is concerned with users’ internal attributes, the interpretive research paradigm is applied. A qualitative research approach is employed and a case study research design is followed. Multiple data-collection techniques, namely semi-structured interviews (17 respondents), open-ended questionnaires (17 respondents) and observations (4 observations) are employed. The study encompasses four public university DLs in Ethiopia. The participants have a positive perception of all attributes of usability. Most of the attributes of usefulness are also perceived positively, except coverage. The major challenges encountered by participants are network accessibility, interruption and speed, and access restrictions imposed on some DL content. DL benefits include easy access to the DL content, enhanced teaching and research, lower cost and easy sharing of contents. The expectations of users are ensuring resource availability and sustainability, overcoming the absence of user feedback and federated search problems, and improving network infrastructure and speed. The interaction triptych framework (ITF), which is used in the current study, is a well-known framework that is commonly implemented by researchers. However, since it does not incorporate the contextual situation of developing countries, ITF has some limitations. Therefore, based on the output of this empirical research and considering the usability and usefulness themes of ITF and its relationships with other socio-technical and contextual themes, a contextual DL evaluation framework is proposed. The proposed framework emphasises the social, institutional and contextual aspects of DLs. The proposed framework has six DL components, namely: DL user; content and collection; system and technology; services and support; user interface; and context. The proposed framework is called a digital library components interaction evaluation framework. / Lo mqondo uhlaziya imitapo yolwazi yedijithali (i-DLs) yezikhungo zokufunda ephezulu zase-Ethiopia ngokusebenziseka kwazo nokuba wusizo. Umphumela unikela ngolwazi ngokusiza ukuhambisa imizamo yentuthuko; ukwanelisa ababambiqhaza be-DL; ukuhlinzeka ngolwazi nokugcwalisa izikhala zolwazi; ukusebenza okubhekiswe kukho kwezifundiswa nabaphenyi emkhakheni; yenza izinqumo futhi ixazulule izingqinamba zokuphatha kuma-DL wezwe elisathuthuka; futhi unikeze izintshisekelo zesayensi kanye nokufaneleka ekuthuthukisweni kwezinhlelo zolwazi. Lapho wenza ucwaningo lokusebenziseka neliwusizo okuhlaziya kuma-DL, akukho luhlaka lomqondo okuvunyelwene ngalo oluhola abacwaningi ezweni elisathuthuka. Ngakho-ke, inhloso ephelele yalolu cwaningo ukuphakamisa uhlaka lokuhlaziya kwe-DL oluhambisana nomongo wamazwe asathuthuka. Njengoba ucwaningo luphathelene nezimpawu zangaphakathi zabasebenzisi, inqubo yocwaningo ehumushekayo iyasetshenziswa. Indlela yokucwaninga esezingeni elifanele iyasetshenziswa bese kulandelwa ukwakheka kocwaningo lwesifundo. Kusetshenziswa amasu amaningi wokuqoqa imininingwane, njengezingxoxo ezihlelwe kahle (abaphenduli abayi-17), imibuzo evulekile (abaphenduli abayi-17) kanye nokubhekwayo (okubhekwayo oku-4). Lolu cwaningo luhlanganisa ama-DL amane wemfundo ephakeme yomphakathi wase-Ethiopia. Abahlanganyeli banombono omuhle wazo zonke izici zokusebenziseka. Iningi lezimpawu eziwusizo zibonwa kahle futhi, ngaphandle kokumbozwa. Izinselela ezinkulu ababambiqhaza abahlangabezana ngazo ukufinyeleleka kwenethiwekhi, ukuphazamiseka nejubane, nemikhawulo yokufinyelela ebekiwe kokunye okuqukethwe kwe-DL. Izinzuzo ze-DL zifaka ukufinyelela okulula kokuqukethwe kwe-DL, ukufundiswa okuthuthukisiwe nocwaningo, izindleko eziphansi nokwabelana okulula kokuqukethwe. Okulindelwe abasebenzisi ukuqinisekisa ukutholakala kwezinsiza nokusimama, ukunqoba ukungabi bikho kwempendulo yomsebenzisi nezinkinga zokusesha ezihlanganisiwe, nokwenza ngcono ingqalasizinda yenethiwekhi nejubane. Uhlaka lokusebenzisana lwe-triptych (ITF), olusetshenziswa ocwaningweni lwamanje, uhlaka olwaziwa kakhulu olusetshenziswa ngokuvamile ngabaphenyi. Kodwa-ke, njengoba lungafaki isimo somongo samazwe asathuthuka, i-ITF inemikhawulo ethile. Ngakho-ke, ngokuya ngokukhishwa kwalolu cwaningo olunamandla kanye nokubheka ukusebenziseka nosizo lwezindikimba ze-ITF kanye nobudlelwano bayo nezinye izingqikithi zomphakathi nezobuchwepheshe nezingqikithi zomongo, kuhlongozwa uhlaka lokuhlaziya lomongo lwe-DL. Uhlaka oluhlongozwayo lugcizelela izici zenhlalo, zesikhungo nezingqikithi zomongo zama-DL. Uhlaka oluhlongozwayo lunezingxenye eziyisithupha ze-DL, okuyilezi: Umsebenzisi we-DL; okuqukethwe neqoqo; uhlelo nobuchwepheshe; izinsizakalo nokwesekwa; isikhombimsebenzisi somsebenzisi nomongo. Uhlaka oluhlongozwayo lubizwa ngohlaka lokuhlaziya kokusebenzisana kokuqukethwe komtapo wolwazi wedijithali. / Hierdie proefskrif evalueer Ethiopië se hoër leerinstellings se digitale biblioteke (DBe) ten opsigte van hulle bruikbaarheid en nuttigheid. Die uitkoms dra by tot kennis wat kan help om die ontwikkelingspogings aan te dryf; om belanghebbers van digitale biblioteke tevrede te hou; om inligting te verskaf en inligtingsgapings te vul; deur te dien as kruisverwysing vir akademici en navorsers in die vakgebied; om besluite te neem en bestuursaangeleenthede in digitale biblioteke van die ontwikkelende wêreld op te los; en om wetenskaplike belange en meriete vir die bevordering van inligtingstelsels te voorsien. Wanneer bruikbaarheids- en nuttigheidsevalueringsnavorsing in digitale biblioteke onderneem word, is daar geen ooreengekome, gevestigde raamwerk wat leiding aan navorsers in die ontwikkelende wêreld kan gee nie. Die algehele doelwit van hierdie navorsing was derhalwe om ’n raamwerk vir die evaluaering van digitale biblioteke voor te stel wat in die konteks van ontwikkelende lande pas. Omdat die studie gemoeid is met gebruikers se interne eienskappe, is die vertolkende paradigma gebruik. ’n Kwalitatiewe navorsingsbenadering is gebruik en ’n gevallestudie-navorsingsontwerp is gevolg. Veelvuldige data-insamelingstegnieke, naamlik semigestruktureerde onderhoude (17 respondente), oop vraelyste (17 respondente) en waarnemings (vier waarnemigs), is ingespan. Die studie sluit vier openbare universiteite se digitale biblioteke in Ethiopië in. Die deelnemers het ’n positiewe persepsie van al die eienskappe van bruikbaarheid. Die meeste van die eienskappe van nuttigheid word ook as positief waargeneem, met die uitsluiting van voorsiening. Die grootste uitdagings wat die deelnemers ervaar het, was netwerktoeganklikheid, -onderbrekings en -spoed en die toegangbeperkings wat sommige digitale biblioteke oplê. Voordele van digitale biblioteke sluit die volgende in: toegang tot digitalebiblioteekinhoud; beter onderrig en navorsing; laer koste; en die maklike deel van inhoud met ander. Die verwagtings van gebruikers verseker hulpbronbeskikbaarheid en -volhoubaarheid, en om die afwesigheid van gebruikersterugvoer en gefedereerde soekprobleme en die verbetering van netwerkinfrastruktuur en -spoed te oorkom. Die interaksietriptiekraamwerk (ITF) wat in hierdie studie gebruik is, is ’n bekende raamwerk wat algemeen deur navorsers geïmplementeer word. Omdat dit egter nie die kontekstuele situasie van ontwikkelende lande inkorporeer nie, het ITF sekere beperkings. Gebaseer op die uitset van hierdie empiriese navorsing en met die inagneming van die bruikbaarheids- en nuttigheidstemas van ITF en sy verhouding met ander sosio-tegniese en kontekstuele temas, word ’n kontekstuele digitalebiblioteekraamwerk derhalwe voorgestel. Die voorgestelde raamwerk beklemtoon die sosiale, institusionele en kontekstuele aspekte van digitale biblioteke. Die voorgestelde raamwerk het ses digitalebiblioteekkomponente, naamlik: digitalebiblioteekgebruiker; inhoud en insameling; stelsel en tegnologie; dienste en ondersteuning; gebruikerkoppelvlak; en konteks. Die voorgestelde raamwerk word ’n interaksie-evalueringsraamwerk vir digitalebiblioteekkomponente genoem. / School of Computing / D. Phil. (Information Systems)

Text in Afrikaans / Summaries in Afrikaans and English / This study aims to investigate and explain how the L2 -facilitator can effectively employ the various facilitation skills of language teaching in Afrikaans Second Language within the Outcomes Based Education framework in the learner-centred classroom. The facilitator is critical in providing an opportunity for multicultural learners to develop the necessary language learning skills to enjoy Afrikaans Second Language/Additional Language learning as an interesting learning experience within a positive learning milieu. In the learner-centred U -classroom, learners too must accept responsibility for their own and their peers' learning within the co-operative learning group. This study reveals how the L2 -facilitator can develop the necessary knowledge and skills concerning groupwork, such as the strategies enhancing L 2 -learning, effective group facilitation skills, learner attitudes towards the facilitator, problem-solving skills, co-operative learning as a control technique, communication, learners' behaviour and the advantages of groupwork. Furthermore, elements of classroom negotiation and the facilitator's methods of working in this negotiated partnership are also discussed. Since language learning is integral to lifelong learning, multicultural learners must be motivated to learn Afrikaans Second/ Additional language with greater enthusiasm. This necessitates the L2 -facilitator creating an interesting, challenging and authentic language learning environment where mutual respect and trust are emphasised. This study reveals how the L2 -facilitator could develop his/her knowledge of task-based L2 -teaching and use it with the effective techniques of facilitation and negotiation skills in the taskorientated second language classroom to lead learners to effective Afrikaans L2 -learning. The new National Language Standardisation Policy 200112002 necessitates the facilitator of Afrikaans L 2 -teaching/learning within the Outcomes Based Education framework and the revised Curriculum 2005 to be aufait with assessment and his/her role in assessment. Being knowledgeable on the various criteria and strategies regarding assessment is therefore imperative. Finally, chapter five illustrates practically how the facilitator could plan, organise, base, integrate and present authentic Afrikaans L 2 -lessons/work based on the theoretical knowledge and aspects of facilitation skills, group-work, task-based learning and assessment discussed in chapters two to four. / Daar word in die studie gepoog om te ondersoek en te verduidelik hoe die T2-fasiliteerder die verskillende fasiliteringsvaardighede ten opsigte van T2 -Afrikaansonderrig binne die UGO -raamwerk in die leerdergesentreerde T2-klaskamer effektief kan gebruik. Die fasiliteerder behoort sy multikulturele leerders die geleentheid te gun om die nodige taalleervaardighede te ontwikkel sodat hulle Afrikaans Tweedetaalleer/ Addisionele Taalleer as 'n interessante leerervaring binne 'n positiewe leerklimaat kan geniet. In die leerdergesentreerde T2 -klaskamer moet die leerders ook die verantwoordelikheid vir bulle eie leer, en vir die leer van ander leerders binne kooperatiewe leergroepe kan aanvaar.

Die verskillende strategiee wat die aanleer van die tweedetaal binne groepwerk bevorder, effektiewe groepsfasiliteringsvaardighede, leerders se gesindhede teenoor die fasiliteerder, die probleemoplossingsvaardighede, kooperatiewe leer as beheertegniek, kommunikasie, leerdergedragswyses en die voordele van groepwerk kom aan bod. Elemente van klaskameronderhandeling en die fasiliteerder se werkswyse in die onderhandelingsvennootskap word ook bespreek.
