- Description: Fingerprints are a non-invasive biometric that possess significant advantages. However, they are subject to surface erosion and damage; distortion upon scanning; and are vulnerable to fingerprint spoofing. The internal fingerprint exists as the undulations of the papillary junction - an intermediary layer of skin - and provides a solution to these disadvantages. Optical coherence tomography is used to capture the internal fingerprint. A depth profile of the papillary junction throughout the OCT scans is first constructed using fuzzy c-means clustering and a fine-tuning procedure. This information is then used to define localised regions over which to average pixels for the resultant internal fingerprint. When compared to a ground-truth internal fingerprint zone, the internal fingerprint zone detected automatically is within the measured bounds of human error. With a mean- squared-error of 21.3 and structural similarity of 96.4%, the internal fingerprint zone was successfully found and described. The extracted fingerprints exceed their surface counterparts with respect to orientation certainty and NFIQ scores (both of which are respected fingerprint quality assessment criteria). Internal to surface fingerprint correspondence and internal fingerprint cross correspondence were also measured. A larger scanned region is shown to be advantageous as internal fingerprints extracted from these scans have good surface correspondence (75% had at least one true match with a surface counterpart). It is also evidenced that internal fingerprints can constitute a fingerprint database. 96% of the internal fingerprints extracted had at least one corresponding match with another internal fingerprint. When compared to surface fingerprints cropped to match the internal fingerprints’ representative area and locality, the internal fingerprints outperformed these cropped surface counterparts. The internal fingerprint is an attractive biometric solution. This research develops a novel approach to extracting the internal fingerprint and is an asset to the further development of technologies surrounding fingerprint extraction from OCT scans. No earlier work has extracted or tested the internal fingerprint to the degree that this research has.

- Description: Project management plays an important role as a common method of reinforcing chosen organisational strategies that leads to sustainable competitive advantage (Steyn, et al. 2013:5). Organisations that respond quickly to customer demands with the use of projects have more opportunities of adding value to their shareholders and increase their market share or responding faster to mitigate risk. A major challenge facing management in many manufacturing organisations is the increasing gap between big investment demands on one hand and the knowledge and expertise on the other hand of the teams that need to make the project a reality. The increasing recognition of failures encountered in projects to meet the expectations of their stakeholders are cited to be jeopardizing the economic development and growth many developing countries like South Africa. As such, organisations are forced to become more resourceful to reduce project failures in an effort to ensure that the positive project outcomes are realized. Relationship management has been identified as one of the aspects that can help improve coordination and communication between all parties involved in a project. As such, emotional intelligence provides a framework for interpersonal skills among project teams, which is claimed to contribute to project success (Clarke, 2010a:14; Davis, 2011:39)The contemporary study, therefore explored the relationship between emotional intelligence (EI) and success in project management. The study was conducted within the context of manufacturing projects in Continental Tyre South Africa (CTSA). Based on the main findings, it was concluded that emotional intelligence plays an important role in project success. Various recommendations from the results of the empirical study are presented in the final chapter.

- Description: The issue of human settlements has recently gained much momentum particularly in cities across the world due to rapid rates of urbanization. The housing crisis is manifesting mostly in the cities of the developing countries; the urban poor population is left with no option, they are continuously living in substandard and unsustainable housing conditions due to the desperate housing need. There is a growing trend of migration into urban centers in the developing countries as well as natural population increase in the cities. The inevitable development is the rapid growth of urbanization. The theories on urbanization suggest that the responsible government and local council authorities must be prepared to address socio-economic issues such as the provision of formal housing, infrastructure development and employment creation. The governments in developing countries are struggling to balance economic development and the provision of social services. As a result, the human settlement sector is suffering lack of prioritization when it comes to budget and resource allocation. The resultant factors are the overcrowding of the urban population, high housing backlogs and dilapidation of infrastructure visible mostly in the major cities of the developing countries.
