This thesis describes a project to create a hardware based 3D interior scanner. This was based on a previous project that created a scanner optimised for interior conditions, using structured light triangulation. The original project referred to as the Mark-I scanner, performed its control and processing on a PC and the primary goal of this project was to re-implement this system using hardware, making the scanner more portable and simpler to use. The Mark-I system required a specialised camera which had an unusually high noise associated with it, so a secondary goal was to investigate whether this camera could be replaced with a superior model or this noise corrected. A Mark-II scanner system was created using FPGA processing and control implemented in the VHDL language. This read from a CMOS camera, controlled the system's motor and laser, generated 3D points and communicated with users. A suitable camera was not found and the Mark-I scanners camera was found to have been damaged and become unusable, so a simulation environment was constructed that simulated the operation of the scanner, created 3D images for it to process, and tested its results. Chapter 1 of this thesis outlines the goals of this pro ject and describes the Mark-I system. Chapter 2 describes the theory and properties of the Mark-I system, and chapter 3 describes the work undertaken to replace the scanner's sensor. Chapter 4 describes the system created to interface to CMOS sensors, and chapter 5 outlines the theory involved in calculating 3D points using structured light triangulation. The final hardware scanner, and the simulation system used to test it, are then described in chapter 6.

The aim of this study was to assess the impact that Business Process Excellence has on the innovation process to create new products and services in the software development environment. The best practices were identified in the current use of BPE in software development organisations. Subsequently, a proposal was put forward to enhance the use of BPE in the software development process to create innovative products and services. Once these products are implemented the organisation can use these products as a sustainable competitive advantage. The use of Business Process Excellence in software development creates an innovative environment for employees in order to develop innovative products that can create shareholder wealth, and increase market share. Companies want to create products that are unique to the market, and be able to offer their customers products that only they can offer in order to secure future business. Innovation is a key factor to enhance processes within the software development company. Enhancing the processes can generate new ideas that contribute to the sustainable competitive advantage of the company. The literature does not create a definite link between the use of Business Process Excellence and innovation, and the study aimed at evaluating the possibility to merge the concepts. Business Process Excellence optimises a currently implemented process, by exploring all ideas to increase the effectiveness of the system. It is a structured way to ensure that all possibilities are explored before a decision is made on how the process is structured to implement new products or services. The software development industry is a very competitive industry, and most companies do not share their competitive strategy, or make it available to the public, to ensure that they would be offering their customer something unique. These companies would only make their strategy known to the market once the new product or service is launched, and the trend is set for other companies to follow. It also creates the opportunity for companies to become the market leader within the industry, to ensure growth, and increase profits. Some key aspects were identified that companies could focus on to encourage an innovative environment. Most employees are willing to accept responsibility for the v innovative ideas, since this will benefit the company. Managers should take responsibility for their actions within the software development department, and reward employees that assist in reaching the goals set in company strategy. The software development process should always include a step for quality and reliability. This step is needed, since even the most innovative product needs to be stable and reliable, otherwise the product will not be used by customers if they are frustrated. / Thesis (MBA)--North-West University, Potchefstroom Campus, 2012.

The pathology report is a key document that contains critical information for the proper diagnosis and prognosis of a patient. It is used to communicate key pathologic findings to users of the pathology report: oncologists who will use this document to base treatment options and cancer registries that use key attributes of cancer cases for surveillance and research purposes. The synoptic report can provide a standard format that contains key information consistency for users of the report. The Vancouver Island Health Authority (VIHA) was the first to adopt this innovative method of pathology reporting within British Columbia. A mixed methods research study design using both qualitative and quantitative techniques to evaluate a synoptic reporting system’s impact on pathology reporting was used in this study. The impact of synoptic reporting was evaluated based on the utilization of the synoptic summaries and the perceived effect on the quality and processes of pathology reporting from the perspectives of pathology reporting stakeholders. Pathology reports obtained from VIHA and British Columbia Cancer Agency (BCCA) databases were audited to obtain information on the amount of synoptic summaries included in pathology reports and whether this inclusion was associated with any pre-defined variables. Pathology reporting stakeholders’ perceptions data was obtained by a self-administered web survey distributed to VIHA pathologists, Victoria location British Columbia Cancer Agency (BCCA-VICC) oncologists and BCCA Cancer Registry management. Out of the reports generated by VIHA pathologists, only 3.5% (593/17430) of them contained a synoptic summary, 5.4% (590/10990) when only considering the pathology reports that were associated to a CAP checklist and activated within the system. According to the VIHA database, it was determined that 16.2% (2819/17430) cases were malignant suggesting that inclusion of synoptic summaries is not being done for the vast majority of malignant cases contrary to expectations. This was further confirmed by the BCCA audit, which contained primarily malignant cases but also had additional non-malignant (benign) cases requested by the BCCA. The BCCA audit revealed that 18.6% (58/312) reports included a synoptic summary, 19.7% (58/294) when only considering the pathology reports that were associated to a CAP checklist and were activated within the system. Differences with the synoptic summary inclusion were found in: individual pathologists, procedures performed, sites of report generation, tumor groups, tumor types, and malignancy status of the specimens. Variation was observed in the perceptions surrounding the quality of the pathology report. Pathologists’ responses were highly variable to the majority of questions in all categories, demonstrating the polarizing views within the community. Pathologists overall had a more favorable opinion of the current pathology report (including synoptic summary) generated, where users (oncologists and registry) had a more favorable opinion of the perceived impact of synoptic summaries on pathology reports and a more favorable opinion regarding improvements that could be made in pathology reporting. While VIHA has taken a significant step forward, being the first health authority in British Columbia to implement synoptic reporting (synoptic summaries), further improvements can be made to better enhance the adoption. / Graduate / 0571 / 0769 / bornfurtado@gmail.com

This thesis investigates the application of structured sequence classification models to multilingual natural language processing (NLP). Many tasks tackled by NLP can be framed as classification, where we seek to assign a label to a particular piece of text, be it a word, sentence or document. Yet often the labels which we’d like to assign exhibit complex internal structure, such as labelling a sentence with its parse tree, and there may be an exponential number of them to choose from. Structured classification seeks to exploit the structure of the labels in order to allow both generalisation across labels which differ by only a small amount, and tractable searches over all possible labels. In this thesis we focus on the application of conditional random field (CRF) models (Lafferty et al., 2001). These models assign an undirected graphical structure to the labels of the classification task and leverage dynamic programming algorithms to efficiently identify the optimal label for a given input. We develop a range of models for two multilingual NLP applications: word-alignment for statistical machine translation (SMT), and multilingual super tagging for highly lexicalised grammars.

This PhD thesis investigates power relationships within a corporate Finance Department employing a Foucauldian approach to explaining corporate hierarchies and resistance and the implications.Research was conducted in the form of a case study and observation of a corporate finance department, referred to as the 'Finance Department', at the 'Company', referred to as such for confidentiality purposes. The Company is a large Dutch based mail and logistics entity that operates internationally across over 200 countries and has its corporate head office just outside of Amsterdam. The Company's Finance Department was in the throws of change, particularly around hierarchies as a result of the reengineering process with the purpose of creating efficiencies. The aim of the research was to evaluate the power relationships that existed within the hierarchies between management and workers who worked either for the Finance Department or closely with it, and to analyse the outcomes of these power relationships in terms of resistance.The case study is a Foucauldian insight into the different individuals who worked either within the Finance Department or closely with it, with an evaluation of their roles and how their differing power structures impacted upon the workflow within the Finance Department.The outcome of this research is an evaluation of those individuals and their relationships at a particular point in time, which was impacted by so many different factors. The research could give readers an understanding of power relationships and framework for contextual Foucauldian evaluation.The significance of the contribution arising from this particular piece of research is that it involves the combination of a case study method with a Foucauldian perspective. The combination of these two elements allows the research to be done both from the top down and also from the bottom up. Increasing in use as a research tool (Hamel, 1992), the case study contributes uniquely to our body of knowledge of individual, organisational, social and political phenomena (Yin, 1994). The Foucauldian perspective plays an important part in terms of an understanding of power, despite the fact that it is often difficult to fully comprehend the meanings behind Foucault's work (McHoul & Grace, 1993).

The fast pace of development in the Mobile Data Services area means innovators have to remain vigilant to stay in the market. There is not time to undertake the usual market development cycles. As a consequence, researchers are looking at various ways to predict the adoption rate of a new product and ways to better forecast adoption in different niche contexts. Rogers’ (2003) provides a review of historical trends in innovation and diffusion studies, and the foundational (1962) model he developed. In the context of the most recent literature, it is found that Rogers’ generic model still works well, but variations built on his model need to be considered. In particular, the ‘Chasm’ model, developed by Moore (1999), adapts Rogers’s model to cope well with the 21st century business environment. Gilbert (2005) has taken the work of both Rogers and Moore and applied the learning to research into adoption rates and characteristics in cross-cultural situations. In New Zealand the past consumer behaviour when new mobile services have been introduced has shown a number of characteristics and specific problems. Vodafone New Zealand provides mobile services only and they now claim 54% market share (Vodafone 2005`). An early success was to significantly lower the cost of sending text messages (SMS), followed by promotion of that service to the teenage market sector. In contrast to the popularity of SMS, introduction of the WAP mobile Internet protocol was not successful in New Zealand, as was the case elsewhere. The failure is commonly attributed to a lack of services being offered to use the technology. Near the end of 2004 Telecom New Zealand launched a new product, branded ‘T3G’. Vodafone New Zealand released ‘Vodafone 3G’ during the middle of 2005. The technologies behind these products is generally called ‘3G Mobile’, or Third Generation Mobile technology. Operators in Singapore also have 3G networks, commissioned during 2004. Authors such as Salz et el (2004) find evidence to suggest that US network operators need to speed up the adoption of this technology to meet predicted demand. There are unique factors likely to affect in the New Zealand market. The OECD has repeatedly found evidence that broadband Internet adoption in New Zealand is lower than other countries. Introduction of 3G technology provides another way to access broadband Internet. The OECD indicates that pricing is one of the barriers to broadband adoption. Telephone companies will have to consider pricing 3G to appeal as an option to having a fixed Internet option. The key question to be addressed in this research is: Do the adoption intensions of New Zealanders match those of Malaysia and Singapore for expected data services use? A related question is: What other factors effect New Zealand's current relatively slow rate of adoption? Product positioning of mobile data products is going to become more critical, given that some telephone operators are ‘expecting to get 25% of revenues from mobile data within five years’ (Molony, 2001). This Thesis will provide information to assist Mobile Service Providers to predict adoption rates of new services. It will also provide a comparative reference for researchers in other countries to replicate the study, and contribute to an exciting body of international literature. The New Zealand market is characterised by high cost of broadband Internet in general (OECD, TUANZ, and others), proprietary knowledge capture, and regulation, but these issues do not stop research into the intensions of potential adopters. This thesis will fill part of that research void, by comparing emergent demand for mobile data with existing models, which have previously been used, to predict future demand. New Zealand has a reputation as an earlier adopter of new technologies (Min Economic Dev & others). This thesis will contribute evidence to indicate how New Zealanders plan to adopt mobile data services, and how intensions of adoption compare with parallel studies in Singapore, and other countries.
