(University of Pretoria, 2001)Especially important in developing improved cochlear implants is to develop a deeper understanding of the processing of sound in the central auditory nervous system, for both acoustic and electrical stimulation of the ...
-
(University of Pretoria, 2007-01-24)A cochlear implant is a prosthetic device that can provide severe-to-profoundly deaf individuals with partially restored hearing. It emulates the function of a normal cochlea through combined functioning of externally ...
-
(University of Pretoria, 2007-01-24)The mining industry can greatly benefit from automation. A great deal of work has been done on this subject and is still ongoing. With automation comes the possibility for optimization, because more information is available, ...
-
(University of Pretoria, 2008-05-19)Please read the abstract in the section, 00front, of this document Copyright 1998, University of Pretoria. All rights reserved. The copyright in this work vests in the University of Pretoria. No part of this work may be ...
-
(University of Pretoria, 2007-01-24)Traditional implementations of optical receivers are designed to operate with external photodetectors or require integration in a hybrid technology. By integrating a CMOS photodetector monolithically with an optical receiver, ...
-
(University of Pretoria, 2007-01-24)HF communication has been used for more than a century and to this day still fulfils an important function in communications networks. In order to interface with modern communications protocols, solutions have to be designed ...
-
(University of Pretoria, 2007-01-24)An important goal of modern data networks is to support multiple applications over a single network infrastructure. The combination of data, voice, video and conference traffic, each requiring a unique Quality of Service ...
-
The design of a simple energy efficient routing protocol to improve wireless sensor network lifetime (University of Pretoria, 2007-01-24)The number of potential applications for wireless sensor networks is immense. These networks may consist of large numbers of low cost, low power, disposable sensor nodes that can be deployed inside or close to phenomena ...
-
(University of Pretoria, 2007-01-24)This dissertation investigates four methods for attacking stream ciphers that are based on nonlinear combining generators: -- Two exhaustive-search correlation attacks, based on the binary derivative and the Lempel-Ziv ...
-
(University of Pretoria, 2007-01-24)An automated detection process for Eukaryotic ribonucleic acid (RNA) Polymerase II Promoter is presented in this dissertation. We employ an artificial neural network (ANN) in conjunction with features that were selected ...
-
(University of Pretoria, 2005)The present explosion in digital communications and multi-user wireless cellular networks has urged a demand for more effective modulation methods, utilizing the available frequency spectrum more efficiently. To accommodate ...
-
(University of Pretoria, 2006-05-16)As the wireless communications networks expand, the number of both unwanted directional interferences and strong nearby sources increase, which degrade system performance. The signal-tointerference ratio (SIR) can be ...
-
(University of Pretoria, 2012-05-18)Anthropogenic changes to forests, agriculture and hydrology are being driven by a need to provide water, food and shelter to more than six billion people. Unfortunately, these changes have a major impact on hydrology, ...
-
(University of Pretoria, 2009-04-08)Physical indoor wireless network testbeds as well as outdoor wireless testbeds have the potential to accelerate the pace of research in the field of wireless ad hoc and mesh networking. They form part of a critical chain ...
-
Correction of radially asymmetric lens distortion with a closed form solution and inverse function (University of Pretoria, 2009-04-08)The current paradigm in the lens distortion characterization industry is to use simple radial distortion models with only one or two radial terms. Tangential terms and the optimal distortion centre are also seldom determined. ...
-
(University of Pretoria, 2009-05-15)This study investigates the signal processing required in order to allow for the evaluation of hearing perception prediction models at low signal-to-noise Ratios (SNR). It focusses on speech enhancement and the estimation ...
-
(University of Pretoria, 2009-04-08)The protein folding problem is examined. Specifically, the problem of predicting protein secondary structure from the amino acid sequence is investigated. A literature study is presented into the protein folding process ...
