Extended Entropy Maximisation and Queueing Systems with Heavy-Tailed Distributions
Numerous studies on Queueing systems, such as Internet traffic flows, have shown to be bursty, self-similar and/or long-range dependent, because of the heavy (long) tails for the various distributions of interest, including intermittent intervals and queue lengths. Other studies have addressed …

Wind plant annual energy production maximisation and efficiency improvement with considerations for thrust and turbulence intensity
Power maximisation in a wind plant (WP) is a necessary and continuous procedure to maintain a cost/benefit ratio required for profit making on the capital investment. Limited land availability with a good wind resource or high land leasing costs imposes close turbine deployments onshore, which …

Resource Allocation for Next Generation Radio Access Networks
… in this thesis we focus on (i) capacity maximisation, (ii) energy efficient configuration of different classes of radio access networks (RANs). To fairly allocate the available resources, we consider proportional fair rate allocations. We first consider capacity maximisation in co-channel …

Statistical-thermodynamical analysis, using Tsallis statistics, in high energy physics
Obtained via the maximisation of a modified entropy, the Tsallis distribution has been used to fit the transverse momentum distributions of identified particles from several high energy experiments. We propose a form of the distribution described in Cleymans and Worku, 2012, and show it to be …

Joint rate control and scheduling for providing bounded delay with high efficiency in multihop wireless networks
… of all incoming traffic, using network utility maximisation framework. The network utility maximisation based approaches to support delay-sensitive traffic have been predominantly based on either reducing link utilisation, or approximation of links as M/D/1 queues. Both approaches lead to …

Exploring the global value chain of gold beneficiation in Zimbabwe
… research confirmed existing literature on value maximisation on the GVC and beneficiation as a strategy was supported by the results and existing literature. A model for value maximisation on the GVC was also developed from the results of this research and will aid managers in crafting …

Regulation of South African agriculture : performance of agricultural marketing boards
… Three possibilities are identified: i) Revenue maximisation ii) Revenue stabilisation iii) Price/quantity stabilisation In view 6f the wide differences between the boards in respect of type of product handled and export possibilities, it is to be expected that they will follow divergent …

Agency costs of free cash flow : the South African experience
… be served if actions of managers lead to the maximisation of the total value of the company. The free cash flow theory suggests that managers have the tendency to misuse surplus cash resources. Any use of free cash flow that is not value maximising could result in losses to shareholders. These …

A comparative analysis between the Companies Act 1995 and the European Union draft Fifth Directive
… business in various ways, regulating profit maximisation and employment. The European Union proposed harmonisation on this matter by introducing the European draft Fifth Directive. This draft was proposed in 1972 followed by several amendments. The aim of this directive is to create an even …

A model of pension portfolios with salary and surplus process
… methods include stochastic control for utility maximisation among others. The optimisation problem entails the optimal investment portfolio to maximise a certain power utility function. We use MATLAB and MAPLE programming languages to generate results in the form of graphs and tables.

Design optimisation of steel portal frames using modified distributed genetic algorithms
