A comparison of the design approach recommended in the South African national standard for a reinforced soil wall with a finite element design to identify an opportunity to optimise the design.
(2019)Reinforced soil structures are used extensively for retaining wall applications in South Africa, with the design methodology recommended within the civil engineering fraternity as specified in the design code SANS 8006-1:2018, ... -
Effect of rainfall on function service quality deterioration of dark roadways and its implication for stopping sight distance.
(2019)Driving in the rain at night is challenging and more so if the roadway has no light. This study aims to ascertain whether rainy dark roadways would have significant influence on functional service quality reduction, and ... -
Optimization of the natural frequency of hybrid, multi-scale graphene/fibre reinforced nanocomposite laminates.
(2020)The optimal solution of the natural vibration problem is investigated in this thesis, for a hybrid, multi-scale graphene/fibre reinforced composite laminate plate. Although several research outputs have been published on ... -
The efficacy of silver/copper nanoparticles in biofilm control on water supply pipeline materials.
(2019)Biofilms are microorganisms that inhabit inside a matrix made mainly of exopolysaccharides that are secreted from the micriobual consortia. Silver and copper ions efficacies have been proven in vitro, but, Huang, et al., ... -
Anaerobic digestion of energy crop (cassava)
(2019)Global energy demand is on the rise due to continuous increases in population, economic growth, and energy usage. Methane production through anaerobic digestion of organic materials provides a resourceful carrier of ... -
The analysis of connected back to back mechanically stabilised earth walls.
(2019)Back to back mechanically stabilised earth walls (MSEW’s) are designed independently as there is a lack of design guidance in the British Standard - Code of practice for strengthened/reinforced soils and other fills ... -
Investigation of the structural response of the groot Olifants River bridge to seismic excitation.
(2019)South African freight railway owner (Transnet fright rail) has over 5000 bridges servicing its railway network. Majority of those bridges are deemed to have exceeded their proposed design lives and cannot support the ... -
Development of a sustainable evolutionary-inspired artificial intelligent system for municipal water demand modelling.
(2020)This study presents the development of a differential evolution (DE)-inspired artificial neural network (ANN) that incorporates climate and socioeconomic information for a more accurate and reliable water ... -
An investigation into the optimisation of small scale anaerobic digestion process systems for rural south Africa.
(2020)South Africa’s rural communities have been historically characterised by persistent service delivery challenges, including: lack of waste management services, poor access to reliable sanitation systems, and inconsistent ... -
Development of ‘green’ rigid pavements incorporating recyclable rubber and paper mill products.
(2019)Natural aggregate resources used as conventional fillers in concrete production are constantly diminishing. Several studies have suggested that there will be a lot of pollution in the degradation of waste rubber products. ... -
An analysis on optimizing the use of sustainable urban drainage systems to provide non-potable water supply in the Isipingo region.
(2019)Population growth and urbanisation lead to increased water demand and stress on water resources. The increased demand implies an increased water treatment cost, utilities therefore charge higher tariffs consequently reducing ... -
An assessment of radar, gauge and kriged gauge rainfall data in Free State, South Africa.
(2019)In the last decades, flooding has caused significant damages and death in South Africa. Flooding is associated with heavy rainfall events which vary largely in space and time. The forecast of such phenomena requires quality ... -
Modelling in ungauged catchments using PyTOPKAPI : a case study of Mhlanga catchment.
(2018)Hydrological modeling of rainfall-runoff processes is a powerful tool used in various water resources applications, including the simulation of water yield from ungauged catchments. Many rivers in developing countries are ... -
A mathematical model development for simulating in-stream processes of non-point source pollutants.
(2018)In coming years, chronic water stress is inevitable owing to the unavailability of fresh water. This situation is occasioned by rapid urbanisation, climate change, rising food demand, and production. The increasing rate ... -
Investigation of the structural behaviour of Megalithic Mnajdra Monument.
(2018)The Maltese megalithic temples are regarded as one of the oldest structures from early civilization dating back to about the 4th millennium. These megalithic structures provide valuable information due to their complexity ... -
Non-linear finite element analysis of the effects of fire protection on a top and seated angle bolted steel connection with double web angles.
(2017)This study was aimed at investigating the performance of steel structures, towards improving fire design, by examining the effects of fire protection on a steel connection exposed to elevated temperatures. A literature ... -
The advancement of the waste resource optimization and scenario evaluation model: the inclusion of socio-economic and instituitonal indicator.
(2018)This study explored Novice Teacher Educators (NTEs) experiences of Relational Learning in a private Higher Education Institution (HEI) in South Africa. The main purpose of this study was to gain a deeper understanding ... -
Modelling the influence of varying sediment sources on coastlines.
(2019)Coastal erosion is of concern to developed shorelines worldwide and has largely intensified due to anthropogenic influences. Sea-level rise, reductions in sediment supply and changes to wave behaviour due to changes in ... -
Numerical evaluation of the dynamic response of structures using auxetic-type base isolation.
(2018)Base isolation is a widely-used method to minimise the harmful effects of earthquakes on buildings. Unlike a fixed base building, a building with a base isolation system essentially decouples the superstructure from the ...
