  1. Parallel process placement
    Handler, Caroline, 1989, Rhodes University
    This thesis investigates methods of automatic allocation of processes to available processors in a given network configuration. The research described covers the investigation of various algorithms for optimal process allocation. Among those researched were an algorithm which used a branch and bound ...
  2. Explanation in rule-based expert systems
    Carden, Kenneth John, 1988, Rhodes University
    The ability of an expert system to explain its reasoning is fundamental to the system"s credibility. Explanations become even more vital in systems which use methods of uncertainty propagation. The research documented here describes the development of an explanation sub-system which interfaces with ...
  3. An integration of reduction and logic for programming languages
    Wright, David A, 1988, Rhodes University
    A new declarative language is presented which captures the expressibility of both logic programming languages and functional languages. This is achieved by conditional graph rewriting, with full unification as the parameter passing mechanism. The syntax and semantics are described both formally and ...
  4. Petrology and geochemistry of the lower group chromitites and host rocks on the farm Zandspruit 168 JP, Western Bushveld Complex
    Botha, Michael James, 1988, Rhodes University
    The eight Lower Group chromitite layers of the Ruighoek Pyroxenite in the area west of the Pilanesberg (LGl - LG7), on the farm Zandspruit 168 JP, were sampled in borehole cores drilled through the succession. The stratigraphic succession faIls within Cameron"s (980) units B to E of the Critical Zon ...
  5. Anorogenic alkaline ring-type complexes of the Damaraland Province, Namibia, and their economic potential
    Potgieter, J E, 1987, Rhodes University
    Anorogenic alkaline ring-type complexes form within continental plate settings. Alkaline magmatism is derived from the upper mantle, in which mantle metasomatism plays an important part, as well as from partial melting of the lower crust. Radial and concentric fractures develop during the ascent of ...
  6. The development of an improved coded-pulse, vertical-incidence ionosonde
    Cretchley, Brian Brind, 1979, Rhodes University
    This thesis describes the theoretical development of a new ionospheric sounding system. The different types of ionosonde, their prime objectives, and their relative merits and demerits are discussed. The various types of code and their correlation functions are described. The essential requirements ...
  7. A re-examination of the Carter solutions of Einstein"s field equations
    Kun, A Ah, 1979, Rhodes University
    The study of geodesics in space-time is essential to a comprehensive understanding of the physics of the field. Global properties, e.g. the singularity structure and completeness of space-time, can be related to the geodesic properties, thus it is through the solutions of the geodesic equation of mo ...
  8. Diamondback Moth, Plutella xylostella (L.), (Lepidoptera: Plutellidae ), and Other Insects of Canola, Brassica napus L., in Gauteng Province, South Africa
    Mosiane, M S, 2002, Rhodes University
    Canola, Brassics napus L. is a relatively new crop in South Africa. Insect pests have not yet been a major problem, but the notorious brassica specialist, diamondback moth (DBM), Plutella xylostella (L.) (Plutellidae) is establishing itself as a serious pest of this crop. DBM is the most important i ...
  9. Evaluating the impact of responsible investing strategies on fund performance
    Ntuli, Thulani, 2017, Rhodes University
    Several studies have been undertaken to evaluate performance of responsible investments, that is, funds that integrate ethical as well as environmental, social and governance considerations in the investment process (ESG). Particularly to address the question whether it is possible for investors to ...
  10. An investigation of the relationship between Corporate Social Responsibility (CSR) and financial performance of companies listed on the Johannesburg Stock Exchange (JSE) in South Africa
    Soko, Leon Lenny Kudzaishe, 2017, Rhodes University
    The purpose of this study is to investigate whether there is an association between CSR and financial performance in South African companies which are listed on the FTSE/JSE SRI Index. Specifically, whether there is a difference in financial performance of companies that perform CSR activities, and ...
