Thesis (MSc)--Stellenbosch University, 2015. / English abstract: We introduce a method for determining the position of a camera with accuracy beyond that which is obtainable through conventional methods, using a single image of a specially constructed calibration object. This is achieved by analysing the moiré pattern that emerges when two high spatial frequency patterns are superimposed, such that one pattern on a plane is observed through another pattern on a second, semi-transparent parallel plane, with the geometry of both the patterns and the planes known. Such an object can be created by suspending printed glass over printed paper or by suspending printed glass over a high resolution video display such as an OLED display or LCD. We show how the camera’s coordinate along the axis perpendicular to the planes can be estimated directly from frequency analysis of the moiré pattern relative to a set of guide points in one of the planes. This method does not require any prior camera knowledge. We further show how the choice of the patterns allows, within limits, arbitrary accuracy of this coordinate estimate at the cost of a stricter limit on the span along that coordinate for which the technique is usable. This improved accuracy is illustrated in simulation. With a sufficiently accurate estimate of the camera’s full set of 3D coordinates, obtained by conventional methods, we show how phase analysis of the moiré pattern in relation to the guides allows calculation of a new estimate of position in the two axes parallel to the planes. This new estimate is shown in simulation to offer significant improvement in accuracy. / Afrikaanse opsoming: Ons stel ’n metode bekend om die posisie van ’n kamera te bepaal met akkuuraatheid bo dit wat verkrygbaar is uit konvensionele metodes, deur gebruik te maak van ’n spesiaal gekonstrueerde kalibrasievoorwerp. Die metode berus op analise van moiré patrone wat onstaan waneer twee hoë ruimtelike frekwensie patrone oor mekaar neergelê word deurdat een patroon op ’n plat vlak waargeneem word deur ’n tweede patroon op ’n parallelle, gedeeltelik deursigtige vlak, met die geometrie van beide patrone en vlakke bekend. So ’n voorwerp kan geskep word deur ’n spesiaal gedrukte glas vlak te monteer oor gedrukte papier of oor ’n hoë resolusie skerm, soos ’n OLED skermof LCD. Onswys hoe die kamera se koördinaat langs die as loodreg op die vlakke direk uit frekwensie analise van die moiré patroon relatief tot ’n stel gidspunte in een van die vlakke bepaal kan word. Hierdie metode vereis geen vooraf kennis oor die kamera nie. Ons wys verder hoe die keuse van patrone, binne perke, arbitrêre akkuuraatheid in die bepaling van hierdie koördinaat kan verkry ten koste van ’n nouer bruikbare verstek in hierdie koördinaat. Die verbeterde akkuuraatheid is geïllustreer in simulasie. Indien ’n benadering van die kamera se volle stel 3D koördinate met voldoende akkuuraatheid ook beskikbaar is, wys ons ook hoe fase analise van die moiré patroon relatief tot die gidspunte ons in staat stel om’n nuwe benadering te kanmaak vir die koördinate in die twee asse parallel aan die vlakke. Daar word in simulasie getoon hoe hierdie nuwe benadering beduidend beter akkuuraatheid kan bied in vergelyking met konvensionele metodes van benadering.

The largest group of English language learners in the United States is comprised individuals who speak Spanish as a first language. There is a growing need for speech-language pathologists to better understand the language development of children learning two languages in order to distinguish between typical and disordered communication with this population. For monolingual English speakers, rate of grammatical morpheme acquisition is typically predicted based on MLU. In bilingual children, current language use has been determined to be a potentially more useful predictor of language performance. The purpose of this study was to determine English grammatical morpheme performance for English-Spanish bilingual preschool-age children based on their language exposure. Data was drawn from two existing data sets that included a total of 314 children. Their performance on the BESA was analyzed for grammatical morphemes in English. Interviews were conducted to determine language use and exposure. We present patterns of English grammatical morpheme acquisition in bilingual children as related to current language use. / text

Diese Arbeit beschäftigt sich mit der Anwendung von Patterns in der Analysephase der Softwareentwicklung. Dazu wird die in der Literatur bisher nicht ausreichend beschriebene Anwendung des Pattern-Ansatzes in der Analysephase aufgearbeitet und anhand von Beispielen konkretisiert. Die in dieser Arbeit gefundenen Hauptvorteile von Analyse Patterns sind die Verwendung von Expertenwissen durch abstrakte Modelle mit konkreten Beispielen und der starke Fokus auf Erfahrungen mit organisatorischen, wirtschaftlichen und sozialen Konsequenzen. Am Beispiel einer Familie von Patterns für Informationsmanagement und deren Anwendung im Rahmen des Projekts 'Virtuelle Universität' an der Wirtschaftsuniversität Wien werden die Vorteile von Analyse Patterns quantifiziert und nachgewiesen.

The internationalization of SMEs has been recognized as one of the important paths to growth in SMEs. However, internationalization is also a resource and competence-demanding process. This is especially true for smaller-sized SMEs – the small and micro-sized firms – which have a large resource constraint, making internationalization even more challenging. Although this group of small firms counts for an average of over 98% of the total population of enterprises in EU countries, extant research on the internationalization of this group is still limited. Therefore, the main purpose of this dissertation is to contribute to a better understanding of evolving patterns of internationalization in the smaller-sized SMEs. The study uses emerging market entry along the internationalization of small firms as a context to probe the dynamics of perceived risk (uncertainty) and perceived opportunity in different foreign markets which influence the important decisions of small firms during their internationalization. The main study takes a longitudinal approach and uses mixed methods to investigate the features in both the initial period and the continued period of internationalization. It mainly builds on a multiple-case study of 12 Swedish firms, which have/had emerging market entry experience and/or involvement. This study illustrates influences from the environmental, organizational and individual levels on evolving patterns of internationalization in the investigated firms. This dissertation concludes that critical decisions and actions taken in the internationalization process depend on interactions among the influence and resources from the three levels. Such interactions form a conditional preference on perceived risk (uncertainty) and perceived opportunity during the internationalization of small firms. The study further proposes that the dynamics in the internationalization process are caused by a prospect-guided change mechanism. This dissertation contributes to the literature by: differentiating patterns of internationalization; enriching the study of “born global” in the continued period of internationalization; introducing a new perspective on the interpretation of dynamics in the internationalization; and increasing the understanding on the interactions of resources from three levels on the internationalization of small firms.
