(University of Pretoria, 2008-07-08)The concept of wireless sensor network (WSN) is where tiny devices (sensor nodes), positioned fairly close to each other, are used for sensing and gathering data from its environment and exchange information through wireless ...
-
(University of Pretoria, 2008-04-24)The main aim of this project was to find a practical and accurate method to determine the parameters of a transmission line by using current and voltage measurements. The term line parameters refer to the inherent series ...
-
(University of Pretoria, 2006-04-18)This dissertation contains a strategy to minimize the non-technical electrical energy losses in an electrical distribution network. In order to develop the strategy, a model was constructed that simulates an electrical ...
-
(University of Pretoria, 2007-04-12)This dissertation investigates the control of the electrical energy input to a three-phase electric arc furnace (EAF). Graphite electrodes are used to convert electrical energy into heat via three-phase electric arcs. ...
-
(University of Pretoria, 2007-04-11)The electricity cost is one of the largest components of operating costs on a belt conveyor system. This dissertation introduces a unique Conveyor Electricity Cost Efficiency Audit Methodology (CECEAM). In the CECEAM the ...
-
(University of Pretoria, 2009-04-08)This research looks into the design of an integrated in-phase/quadrature (I/Q) VCO operating at 5 GHz. The goal is to design a phase shifter that is implemented at the LO used for RF up conversion. The target application ...

(University of Pretoria, 2009-04-28)Please read the abstract in the section front of this document
-
(University of Pretoria, 2005)The objective of this dissertation is to enhance the functionality of an existing simulation package that is used to simulate fiber optic networks. These enhancements include the capability to simulate protection mechanisms ...
-
(University of Pretoria, 2007-04-05)Optical fibre networks play an increasingly prominent role in communications. As networks grow in size and complexity, the probability and impact of failures increase. In this dissertation, different optical network concepts, ...
-
(University of Pretoria, 2007-01-17)Against the background of the rapid evolution of mobile communication systems in the areas of service provision and capacity enhancement described above, the main focus of the research is on coded space-time processing ...
-
(University of Pretoria, 2005-04-07)The objective of this dissertation is to investigate the factors that influence the design of wide-area wavelength division multiplexing (WDM) optical networks. Wide-area networks are presented as communication networks ...
-
(University of Pretoria, 2012-05-02)Sensor nodes in a wireless sensor network (WSN) have a small, non-rechargeable power supply. Each message transmission or reception depletes a sensor node’s energy. Many WSN applications are ad-hoc deployments where a ...
-
(University of Pretoria, 2011)Wireless Sensor Networks are the main representative of pervasive computing in large-scale physical environments. These networks consist of a large number of small, wireless devices embedded in the physical world to be ...
-
(University of Pretoria, 2009-06-18)The goal of this study was to investigate the methodology in designing a vowel intelligibility model that can objectively predict the outcome of a vowel confusion test performed with normal hearing individuals listening ...
-
(University of Pretoria, 2007-01-12)In this thesis an eye-directed controller is developed that slaves the narrow field display within a split-foveal-peripheral-display system to the operator's gaze position. A neural network controller is proposed that ...
-
Design and development of an on-line vending system for selling prepaid electricity via the Internet (University of Pretoria, 2007-06-26)The sale of prepaid electricity is prevalent in South Africa due to the current economic, social, and political conditions. The system currently used for the distribution of tokens for prepaid electricity, CVS, has a design ...
