Drivable region detection for autonomous robots applied to South African underground mining
(2012)
This dissertation focuses on enhancing autonomous robots' capability to identify drivable regions in underground terrains. A system model that compares the drivability analysis of underground terrains using the entropy ...
Uncertain input estimation with application to Kalman tracking
(2011)
Many motion tracking systems average and integrate
tracking measurements over a period of time in order to reduce the effects of device noise, external
noise and other disturbances. The target (user) is likely to be ...
The design considerations and development of a simulator for the backtesting of investment strategies
(2011)
The skill of accurately predicting the optimal time to buy or sell shares on the stock market is one that has been actively sought by both experienced and novice investors since the advent of the stock exchange in the early ...
Context-aware handoff support for wireless access networks
(2010)
The phenomenal emergence of several heterogeneous wireless networks and technologies has allowed users to have access to IP services anywhere, at anytime, from any network and with whatever terminal they use. This computing ...
Mobile media distribution in developing contexts
(2011)
There are a growing number of mobile phones being used in developing contexts, such as Africa. A large percentage of these phones have the capability to take photographs and transmit them freely using Bluetooth. In order ...
Supporting NGO intermediation with internet systems : comparing mobile and web examples for reaching low income urban youth of Cape Town
(2014)
Intermediaries are necessary to overcome challenges of Internet use for many users in the developing world. However the need for co-presence with intermediaries can be inconvenient for beneficiaries, and the process is ...
Generalised Markovian analysis of timed transition systems
(1996)
This dissertation concerns. analytical methods for assessing the performance of concurrent systems. More specifically, it focuses on the efficient generation and solution of large Markov chains which are derived from models ...
Information visualisation
(1996)
Information visualisation uses interactive three-dimensional (3D) graphics to create an immersive environment for the exploration of large amounts of data. Unlike scientific visualisation, where the underlying physical ...
The efficient evaluation of visual queries within a logic-based framework
(1995)
There has been much research in the area of visual query systems in recent years. This has stemmed from the need for a more powerful database visualization and querying ability. In addition, there has been a pressing need ...
A parallel multidimensional weighted histogram analysis method
(2014)
The Weighted Histogram Analysis Method (WHAM) is a technique used to calculate free energy from molecular simulation data. WHAM recombines biased distributions of samples from multiple Umbrella Sampling simulations to yield ...
