Investigation of the structural response of masonry systems using traditional and data-driven numerical techniques.
(2022)The understanding of the structural behaviour of masonry structures is of great importance for the preservation of their structural integrity and restoration. Masonry arches are among the oldest structural systems in the ... -
Development of an integrated model for urban sustainable resilience through smart city projects in the Southern African context.
(2021)The construct Smart City has gone through a few phases in the last decades. Today there is still no consensus on an accurate definition of Smart City, even though a few concepts are now accepted by most stakeholders, ... -
Influence of rainfall on red-light running at signalised intersections and the service quality implications.
(2021)When drivers approach a signalised intersection stop-line, they must decide whether to stop or proceed and clear the intersection before the end of a green phase. The driver behaviour at the intersection affects signalised ... -
Development of a universal water quality index and water quality variability model for South African river catchments.
(2020)The assessment of water quality has turned to be an ultimate goal for most water resource and environmental stakeholders, with ever-increasing global consideration. Against this background, various tools and water quality ... -
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 ... -
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 ... -
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 ... -
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 ... -
The applicability of C&D waste material in South Africa road construction.
(2015)In contrast to developed countries, South Africa is starting to adopt the practice of using recycled rubble from civil engineering demolition works in road construction. This change is due to environmental considerations, ... -
Circular economy design visioning: exploring industrial and urban symbiosis in South African cities.
(2017)Cities of tomorrow will be at the coalface of the complex challenges posed by climate change, e.g. resource scarcity. Climate change adaptation strategies will include circular economy (CE) practices (e.g. industrial and ... -
Influence of rainfall on quality of service at multilane roundabouts and its time headway implications.
(2018)Roundabouts, or traffic circles as they are often called in South Africa, are priority intersections with a unique yield rule. Drivers approaching the roundabout must give way to those that are already circulating the ... -
The applicability of C&D waste material in South Africa road construction.
(2018)In contrast to developed countries, South Africa is starting to adopt the practice of using recycled rubble from civil engineering demolition works in road construction. This change is due to environmental considerations, ... -
Development of a mathematical model considering nutrients kinetics for assessing uMgeni river water quality.
(2018)Surface water is an essential component of the natural environment which needs to be sheltered from all sources of contamination because human and aquatic animals depend on it for their survival. However, the discharge of ... -
Flood estimation in developing countries with case studies in Ethiopia.
(2017)Extreme flood events have become more destructive in some parts of Ethiopia. Thus, accurate estimates of flood frequencies are vital for effective flood risk management. Yet, estimation of the peak flood is exceptionally ... -
An investigation into the reduction of greenhouse gases associated with the disposal of municipal solid waste for the development of an institutional framework in developing countries.
(2015)Municipal solid waste in landfills releases the greenhouse gas (GHG), methane. This study aimed to develop an institutional framework that could assist municipalities in developing countries to adopt an integrated waste ... -
On weather and waves : applications to coastal engineering.
(2015)Shoreline erosion in response to extreme wave events can be severe. The reduction in beach width leaves development within the hinterland exposed and vulnerable to future wave attack. Wave climates are a fundamental ... -
The use of commercial garden refuse at different degrees of maturity as an organic carbon source to bio-denitrify treated MSW landfill leachate.
(2014)Abstract available in PDF file. -
Maximising the photobiological production of hydrogen using leachate, while monitoring algal photosynthesis using pam fluorometry.
(2014)Hydrogen is universally known as the most efficient renewable energy source capable of meeting global energy demands. Chlamydomonas reinhardtii has the ability to produce biohydrogen during the metabolic engineering of ... -
Effective HIV and AIDS management : a South African construction sector model.
(2013)Abstract available on PDF file. -
An investigation into the emissions of greenhouse gases associated with the disposal of solid waste in the eThekwini Municipality.
(2013)The amount of greenhouse gases (GHG) emitted due to waste management in the cities of developing countries is predicted to rise considerably in the near future; however, these countries have a series of problems in accounting ...
