- Description: Software-Defined Networking (SDN) is a paradigm which enables the realisation of programmable network through the separation of the control logic from the forwarding functions. This separation is a departure from the traditional architecture. Much of the work done in SDN enabled devices has concentrated on higher end, high speed networks (10s GBit/s 100s GBit/s), rather than the relatively low bandwidth links (10s MBit/s to a few GBit/s) which are seen, for example, in South Africa. As SDN is increasingly becoming more accepted, due to its advantages over the traditional networks, it has been adopted for industrial purposes such as networking in data centres and network providers. The demand for programmable networks is increasing but is limited by the ability of providers to upgrade their infrastructure. In addition, as access to the Internet has become less expensive, the use of Internet is increasing in academic institutions, NGOs, and small to medium enterprises. This thesis details a means of building and managing a small scale Software-Defined Network using commodity hardware and open source tools. Core to the SDN Network illustrated in this thesis is the prototype of a multi-layer SDN switch. The proposed device is targeted to serve lower bandwidth communication (in relation to commercially produced high speed SDN-enabled devices). The performance of the prototype multilayer switch had shown to achieve: data-rates of up to 99.998%, average latencies that are under 40µs during forwarding/switching and under 100µs during routing while using packet sizes between 64 bytes and 1518 bytes, and a jitter of less than 15µs during all tests. This research explores in detail the design, development, and management of a multi-layer switch and its placement and integration in small scale SDN network. This includes testing of Layer 2 forwarding and Layer 3 routing, OpenFlow compliance testing, the management of the switch using created SDN applications, and real life network functionality such as forwarding, routing and VLAN networking to demonstrate its real world applicability.

- Description: This dissertation examines the theme of hybrid identities in Mabanckou, Laferrière, Beyala and Wekape’s novels : Black Bazar, Le Petit prince de Belleville, Je suis un écrivain japonais and J’appartiens au monde. Hybrid identity raises the issue of identity diversity and contemporary francophone literature is characterised by the emergence of fictional narratives increasingly numerous. This research undertaken is driven by the desire to extend the field of investigation in francophone literature by taking into account a varied corpus of Haitian, Congolese, and Cameroonian literatures. I have opted for writers who settled in a foreign country and have adopted a foreign language that they considered to be part of a foreign literary world; writers who are between two or more cultures which they depict in French. The few existing studies on hybrid identities on these four novels focused more on formal and linguistic analysis and omitted meaningful sociocritic analysis. It is clear that a full study on sociocritic approach on hybrid identity on these four authors remains to be done. The research is demonstrating how different characters created by these four postmodern immigrant French-speaking writers occasionally function similarly in their texts. This gives a clear understanding of the specific behaviour of immigrants characters, vis-à-vis their various situations in the novels, and how these immigrants seek to address the problems they encounter. As this research offers reflections related to the identities and nationalities of immigrants, Laferrière, Mabanckou, Beyala and Wekape’s texts are based on the search for social belonging and a literary membership in this modern world. Therefore, they are analysing their position in a literary field as well as in a social field. In their texts they highlight the Space real or imaginary. In which way and how this Space contribute to the evolution of francophone literature? To what extent does francophone literature takes into account this representation of the Space? These questions lead to a reflection on the position occupied by these authors in the francophone field and the source of their literary inspirations. My interest in these authors is motivated by the fact that, by living and writing in a country which is not their place of birth, they each reveal different aspects of hybrid identity. Each of them, has his or her personal and original way of tackling the problem of mixed identity. They present their characters in different situations and different contexts, showing that each has been in contact with several cultures which they have assimilated and each lived in his or her own way a particular story. My study’s focus is to understand the problems of contact of cultures and their consequences, and to explore how through the characters of the novel, immigrant French speaking writers understood their acculturation as themselves have experienced an identity crisis, resulting from the confrontation of the culture of their new homeland and the culture of their country of origin. For this reason, Bourdieu’s approach “la sociocritique” will help me to found out the origin of the author’s obsession with the question of hybrid identity. I have chosen these four immigrant speaking writers to explore the strategies implemented by the novels’ narrators to construct their identities and to find out how the narrators express the intentions of the authors. In their texts, Mabanckou, Beyala, Laferrière and Wekape have used various strategies to express the quest for identity which gives clear indications of the authors’ creativity such as humour, parody, or solemnity and gravity - and the narrative voices reveal distinctive attitudes in relation to hybrid identity. At this level, other approaches will also be called for, such as the work of Westphal, Doubrovsky, Genette, Colona, etc. Through my investigation, these works present similarities and dissimilarities. Each author tackled the questions of hybrid identities according to his own experience. From there, a different commitment emerges, depending on the degree of inquiry into questions about immigration. These authors all evoke the social precariousness of their characters or the immigrant and privilege an urban framework. The examination of these works allowed me to identify their place in Francophonie literature and to discover the importance of their texts. The four novels relate to the search for identity, an aesthetic way and a search for freedom. They possess aesthetic qualities, they have a high degree of coherence. Their romantic choice shows their creativity and their strategies engender a hybrid writing that stems from their position between several languages and place these novels within the world literature.

- Description: This treatise addresses the architectural challenge of designing a High Performance Centre (HPC), serving South African Sailing (SAS), to be located in Port Elizabeth’s harbour. Designing a facility which caters speciffically to the functional requirements of sailing racing and recreation will cater to the needs of SAS, whilst upgrading the state of Port Elizabeth’s oceanic recreational facilities, thereby boosting the local tourism sector by establishing Port Elizabeth as South Africa’s watersport capital. The current status of the harbour as an area undergoing a redevelopment from a heavy industrial focus to a recreational and commercial waterfront provides the opportunity for an architectural intervention which spearheads this shift, whilst addressing the postindustrial landscape which remains. A study of the nature of the sport of sailing is conducted in order to determine the requirements of facilities catering for sailing racing and recreation, and to supplement an investigation of the typology of the HPC which, through the study of precedents, clarifies its specific nature and characteristics. This results in the development of a set of site selection criteria, which inform the best possible location for such an intervention within the harbour. In depth contextual analysis is conducted in order to determine role of the harbour within PE’s urban, ecological and historical fabrics, from which the current development plans of the Nelson Mandela Bay Development Agency and Transnet are outlined so as to understand the direction in which the future of the PE harbour is headed, and to align an architectural response with this vision. This analysis sets up a number of contextual constraints and informants which, with the aid of phenomenological concepts of place-making and materiality, the principles architectural responses to post-industrial landscapes, and the nature of the relationship between architecture and water, guide the design process, ensuring an appropriate response to the site.

- Description: This study seeks to generate a model that will give rise to improved working relations between the management of the Eastern Cape Provincial Legislature and NEHAWU. In the community of the Eastern Cape Provincial Legislature there are perceptions that management and NEHAWU do not trust each other. Based on the above, the main aim of the study therefore is to investigate the truth or falsehood of the perceptions mentioned above and to generate a model. As Punch (1993:37) explains, the researcher provides the hypothesis which is the predicted answer to the research question or problem identified in the study. The formulated hypothesis in this study is that “the application of a model to improve working relations will result in improved working relations between management of the Eastern Cape Provincial Legislature and NEHAWU”. Findings revealed in the answers received from respondents prove the accuracy of the hypothesis. The methodological framework used in this investigation is the qualitative research. Winberg (1997:411) states that in using the qualitative research approach, the researcher looks at people within a specific context. An appropriate research design selected for this research project is the empirical study that utilises the primary data sourced through a survey. A v survey has been conducted targeting different respondents in the legislature community. Findings reveal that in order to improve working relations an enabling environment in the ECPL should be created. Effective and user friendly systems and standard operating procedures should be put in place. Findings also reveal that interaction between management and the union takes place mainly around bargaining issues. Managament and NEHAWU do not trust each other and as a result of that relations are poor. Again, findings reveal a strong support by management and NEHAWU for the development of a “model to improve relations between management of the Eastern Cape Provincial Legislature and NEHAWU”. After analysing and interpreting the findings, the study recommends a model that will help improve working relations between management and NEHAWU. The proposed integrated model deals with institutional strategy that is informed by national policies and legislations, structure (inclusive of MPLs, management and the labour union), systems and standard operating procedures and cultural re-invigoration. Central to this model is an effort to build a team with a common purpose. The model recognises the importance of inter-relation and inter-dependency of its various elements in order to build a successful organization and to cultivate good corporate governance.

Her short stories are handled briefly in connection with her novels. For, although the short stories are among her finest work, focus on the novels is sufficient to show her growth as a writer. Hers is the small individual struggle to overcome the limitations of both her content and her form. To overcome the limitations of her content means expanding her own consciousness and re-forming life itself. Only when she is free and the world is free can she overcome the limitations of her content. Then, of course, she need no longer and can no longer write. The task seems as impossible as that of the dung beetles, but she nevertheless continues. Like the sacred beetles with "the sun between their feet" she carries on rolling the muck of the world into symbols of the truth.

The scientific names, their spelling, authors and dates, have been carefully checked and brought into line with the most recent revisions available. However, the tremendous outpouring of scientific papers will make some scientific names obsolete even while this checklist is being printed. Also there will continue to be additions to the fauna and this, the first list to be published, must be regarded as a foundation on which subsequent lists can be based.
