(University of Pretoria, 2021)The task of detecting and separating multiple radio-frequency signals in a wideband scenario has attracted much interest recently, especially from the cognitive radio community. Many successful approaches in this field ...
-
(University of Pretoria, 2021)Autonomous mobile robots became an active research direction during the past few years, and they are emerging in different sectors such as companies, industries, hospital, institutions, agriculture and homes to improve ...
-
(University of Pretoria, 2021)Since the popularisation of media streaming, a number of video streaming services are continually buying new video content to mine the potential profit. As such, newly added content has to be handled appropriately to be ...
-
(University of Pretoria, 2021)The advancement of wireless technology has led to an increase in the employment of wireless sensor networks (WSNs). Traditionally, WSNs are powered by batteries. However, the high power consump- tion and the need to change ...
-
(University of Pretoria, 2021)Security is a key challenge for any IIoT network and more so for constrained IWSN deployments. Novel methods are thus required to enhance security, taking into consideration the lossy and low power nature of the IWSN. ...
-
(University of Pretoria, 2021)Given the high prevalence of Tuberculosis (TB) and the mortality rate associated with the disease, numerous models, such as the Gammaitoni and Nucci (GN) model, were developed to model the risk of transmission. These models ...
-
(University of Pretoria, 2020)The use of solar photovoltaic systems has increased in the past years in an effort to move towards cleaner energy sources. Solar panels are however affected by negative factors such as dust deposition which hinder their ...
-
(University of Pretoria, 2020)Cognitive radio networks (CRNs) have emerged as a solution for the looming spectrum crunch caused by the rapid adoption of wireless devices over the previous decade. This technology enables efficient spectrum utility by ...
-
(University of Pretoria, 2020)With the ongoing trend in moving the upper levels of the automation hierarchy to the cloud, there has been investigation into supplying industrial automation as a cloud based service. There are many practical considerations ...
-
(University of Pretoria, 2020)In deregulated electricity markets, profit driven electricity retailers compete to supply cheap reliable electricity to electricity consumers, and the electricity consumers have free will to switch between the electricity ...
-
(University of Pretoria, 2020)A detailed mathematical modelling framework for the risk of airborne infectious disease transmission in indoor spaces was developed. This modelling framework enables the mathematical analysis of experiments conducted at ...
-
(University of Pretoria, 2014)The current approach for person identification consists of handing over a paper ID document which consists only of a picture of the person’s face, usually at a much younger age. Human intuition provides the means to make ...

(University of Pretoria, 2020)In this report, the development of flexible OLED-based (organic light-emitting diodes) light emitter and detector array is discussed for low-cost colourimetric analysis of water samples. LEDs have been used as optical ...
-
(University of Pretoria, 2021)Several heterogeneous, intelligent and distributed devices can be connected to interact with one another over the internet in what is known as the internet of things (IoT). Also, the concept of IoT can be exploited in the ...
-
(University of Pretoria, 2019)By placing clusters of renewable-based AC microgrids in low-voltage radial distribution networks, emergent energy demands can be met. However, this leads to fundamental changes and challenges in the topology and protection ...
-
(University of Pretoria, 2020)Motorsport has become a multidisciplinary sport in which skilled engineers and strategists play as big a part in the team’s success as the athlete driving the car. In Formula One it is common practice for teams to have ...
-
(University of Pretoria, 2019)The global growth in demand for transportation has been phenomenal, owing to an exponential increase in population, industrialization and urbanization. This has led to a corresponding increase in the number of motor vehicles ...
-
(University of Pretoria, 2020)The lighting retrofit method is adopted as one of the solutions to reduce lighting energy consumption and improve lighting quality in existing buildings. Lighting controls and energy-efficient light sources are used to ...
-
(University of Pretoria, 2016)Models are developed and verified with industrial data. These models are then controlled using nonlinear model predictive control (NMPC). It was found that there are very few available dynamic models for coal processes, ...
