-
(University of Pretoria, 2015)Cochlear implants have successfully been used to enable hundreds of thousands of profoundly deaf people to regain some perception of hearing. Hearing performance does, however, vary greatly among individual implant users. ...
-
(University of Pretoria, 2015)Communicating Sequential Processes (CSP) is arguably one of the most widely used process algebras. It has been extensively studied and expanded since its inception in the late 1970s. One of the fundamental assumptions ...
-
(University of Pretoria, 2015)High-speed digital to analogue converters (DAC), which are optimised for large bandwidth signal synthesis applications, are a fundamental building block and enabling technology in industrial instrumentation, military, ...
-
(University of Pretoria, 2014)Traditionally, the effectiveness of a phase overcurrent protection philosophy has been assessed by only considering a fault level versus protection operating time graph (only selectivity). In this research, an improved ...
-
(University of Pretoria, 2014)In this study, a method is developed for modelling and classifying behaviour of maritime vessels in a piracy situation. Prior knowledge is used to construct a probabilistic graphical model of maritime vessel behaviour. ...
-
(University of Pretoria, 2014)Wireless Sensor Networks have received significant attention due to their capability for distributed sensing at relatively low cost, in applications which range from environmental to industrial monitoring. More recently, ...
-
(University of Pretoria, 2014)The optimal placement of reclosers on overhead lines in a medium voltage distribution network is known to improve the reliability of a power system. Traditionally, recloser placement studies have not considered the effect ...
-
(University of Pretoria, 2014)With the growing concerns about energy shortage and demand supply imbalance, demand side management (DSM) activities has found its way into the mining industry. This study analyzes the potential to save energy and ...
-
(University of Pretoria, 2014)An energy saving opportunity exists in mining and smelting industries such as the Ferrochrome industry, in the form of waste heat extraction and recovery. The mining and smelting of metals requires the use of high-power, ...
-
(University of Pretoria, 2015)Conventional rectangular waveguides are commonly used for high power and millimetre wave microwave applications. However their use at lower frequencies has been limited by their bulky nature at these frequencies. A new ...
-
(University of Pretoria, 2015)A run-of-mine ore milling circuit is primarily used to grind incoming ore containing precious metals to a particle size smaller than a specification size. A traditional run-of-mine (ROM) ore single-stage closed milling ...
-
(University of Pretoria, 2015)In South Africa, where 75% of the worlds platinum is produced, electricity tariffs have increased significantly over recent years. This introduces challenges to the energy intensive mineral processing industry. Within the ...
-
(University of Pretoria, 2015)This dissertation focuses on daily volt/var control in distribution networks with feeder capacitors, substation capacitors and transformers equipped with on-load tap changers. A hybrid approach is proposed to solve the ...
-
(University of Pretoria, 2014)An accurate measurement of retrofitted loads is essential for the quantification of energy savings in an energy conservation measure project. This research presents an optimal meter placement approach to an ECM project ...
-
(University of Pretoria, 2014)The industry of wireless digital communications has matured since the 1970s with the introduction of cellular technology, to the present rollout of fourth generation infrastructure. The discovery and refining of technology ...
-
(University of Pretoria, 2014)Recipients of present-day cochlear implants (CIs) display remarkable success with speech recognition in quiet, but not with speech recognition in noise. Normal-hearing (NH) listeners, in contrast, perform relatively well ...
-
(University of Pretoria, 2014)Modern pulse-Doppler radars use digital receivers with high speed ADCs and sophisticated radar signal processors that necessitate high data rates, computationally intensive processing, and strict latency requirements. ...
-
(University of Pretoria, 2014)The large unlicensed 3 GHz overlapping bandwidth that is available worldwide at 60 GHz has resulted in renewed interest in 60 GHz technology. This frequency band has made it attractive for short-range gigabit wireless ...
-
(University of Pretoria, 2014)The Discrete Pulse Transform (DPT) is a hierarchical decomposition of a signal in ndimensions, built by iteratively applying the LULU operators. The DPT is a fairly new mathematical framework, with few applications, and ...
-
(University of Pretoria, 2014)Maritime Domain Awareness is the understanding of all aspects relating to the maritime domain that may have an effect on the security, economy or environment of a country bordering the sea. Large ships in South Africa ...
