-
(University of Pretoria, 2016)One of the problems facing wireless network planners is a perceived scarcity of spectrum. A technology that addresses this problem is cognitive radio (CR). A critical function of a CR network is spectrum sensing (SS). A ...
-
(University of Pretoria, 2016)Multimodal dataset shifts consisting of both concept and covariate shifts are addressed in this study to improve texture-based land-use classification accuracy for optical panchromatic and multispectral remote sensing. ...
-
(University of Pretoria, 2015)The modelling of contagion spread on contact networks provide valuable insights to epidemiologists and policymakers trying to control and eradicate diseases. This thesis proposes, implements and analyses a methodology ...
-
(University of Pretoria, 2016)To the knowledge of the authors, studies making use of cellular network counters to analyse the impact of solar originated radio waves on cellular telecommunication systems are a relatively unexplored area. This dissertation ...
-
(University of Pretoria, 2015)Current research indicates that optimal control methods can be used to control heating ventilation and air-conditioning (HVAC) systems with ice-storage tanks installed in commercial buildings that employ a time-of-use ...
-
(University of Pretoria, 2015)The aim of this dissertation was to investigate peak-to-average power ratio (PAPR) reduction techniques for filter bank multicarrier (FBMC) modulated systems. Research into current PAPR reduction techniques in FBMC and ...
-
(University of Pretoria, 2015)For more than a decade research in wireless sensor networks has received much attention. Several wireless sensor network standards have been proposed and are still being developed. In precision agriculture, specifically ...
-
(University of Pretoria, 2016)Given the widespread adoption of cellular-phones, it can be assumed that the presence of a phone can predict with good certainty the presence of a human being. Therefore the location of phones in restricted areas can aid ...
-
(University of Pretoria, 2015)Residential demand response (RDR) is one of the demand side management (DSM) programs for smart grid applications that are designed to enable utility companies to manage the userside electrical loads and also for consumers ...
-
(University of Pretoria, 2015)In this study, a measurement and verification (M&V) cost minimisation model is proposed to deal with both the M&V modelling and sampling uncertainties. In order to find the optimal solutions in terms of the modelling ...
-
(University of Pretoria, 2015)The energy management of today s power system is of utmost importance because of the increasing complexity of today s power system operations. One of the core energy management functions is determining the optimal dispatch ...
-
(University of Pretoria, 2015)The operation of any petrochemical plant requires the transfer of energy to and from the process, movement of material through the process piping and vessels and suppression of unwanted reaction or combustion. This is ...
-
(University of Pretoria, 2015)Wireless networks are gaining widespread use and popularity because of their progressive increase in affordability and convenience. Owing to the improved facilitation of communication and data transfer, wireless networks ...
-
(University of Pretoria, 2015)There exists a need to be able to acquire high data speed over a wide bandwidth. This requires the use of an analogue-to-digital converter (ADC) capable of achieving wide input bandwidth. With the 60 GHz unlicensed band, ...
-
The impact of social networks on energy efficiency projects : the information propagation approach (University of Pretoria, 2015)There are many reasons why energy efficiency projects are carried out; to reduce electricity and water usage, cut greenhouse gas emissions and to promote the conservation of biodiversity. A common factor is that humans ...
-
(University of Pretoria, 2015)The Internet of Things has become a hugely popular field of research. This is due to the effect that the application of this range of technologies could have on an individual’s daily life. These technologies could be ...
-
(University of Pretoria, 2015)Measurement and Verification (M&V) has become an indispensable process in various incentive energy efficiency and demand side management (EEDSM) programmes to accurately and reliably measure and verify the project ...
-
(University of Pretoria, 2015)Renewable energy-based hybrid systems have become attractive energy supply options in many countries because of global environmental concerns, access to electricity, and depleting and rising cost of fossil fuel resources. ...
-
(University of Pretoria, 2015)Solar water heating systems (SWHS) have fast become a suitable alternative to conventional water heating systems due to growing energy demands. A SWHS generally consists of a solar collector (which is used to convert ...
-
(University of Pretoria, 2015)It has been shown that mining processes, especially the comminution processes (grinding and crushing) are some of the biggest consumers of electricity in the world where energy management application would have a significant ...
