A fundamental aspect of the characterization of any soil is the assessment of its particle
size distribution. While this is relatively easy for the coarse fraction it remains problematic for soil fines
particularly for ...
Monye, P.K.; Stott, P.R.; Theron, E.(Bloemfontein: Central University of Technology, Free State, 2017)
For many years the hydrometer was the only technique that was internationally standardised for geotechnical particle size distribution analysis of fine soils. Nettleship et al. (1997). Recently Britain has added the pipette ...

The South African government's attempts to provide affordable, subsidised housing for
the very poor has suffered from a large number of structural failures, many due to heaving foundations.
These houses are particularly ...

This paper presents a study conducted on three active clay soils analysed at seven commercial
laboratories in South Africa. Commercial test results are often used as input parameters for prediction models
used to estimate ...
Das, Dillip Kumar; Honiball, James Edward(ICE Publishing: Proceedings of the Institution of Civil Engineers - Municipal Engineer, 2017)
Underutilisation of public parks in the residential areas of South African cities is a challenge. Although accessibility,
environmental and social factors are argued to be some of the challenges for the utilisation of ...
Emuze, Fidelis A.; Das, Dillip Kumar(Proceedings of the Institution of Civil Engineers - Municipal Engineer, 2015)
Safer and reliable infrastructure in cities is a necessity for urban dwellers. The question is whether conventional planning practices would provide solutions before urban roads are labelled as unmanageable sources of ...
Swart, Arthur James(IEEE Xplore: IEEE AFRICON, 2017)
Renewable energy systems are receiving more
and more attention, as governments and industry seek to reduce
fossil fuel usage and provide more clean energy. PV systems fall
into this category, and are especially sought ...
Swart, Arthur James(IEEE Global Engineering Education Conference (EDUCON), 2017)
Learning management systems have the capabilities
of creating, fostering, delivering, and facilitating learning at
anytime and anywhere, allowing students to engage in online
discussion and collaborative activities. ...
Universities of Technology must enable students to
acquire the necessary knowledge (theory), workplace skills
(practice), and graduate attributes (theory and practice) needed to
meet the needs of industry, business and ...
Swart, Arthur James; Hertzog, Pierre Eduard(IEEE Xplore: IEEE Global Engineering Education Conference (EDUCON), 2017)
In 2016 alone, Google Scholar listed 301 results for
“student unrest”. These results listed countries such as South
Africa, Nigeria, India, Canada and the USA. The devastating
effects of student unrest on student ...
Potgieter, Pieter; Blignaut, Pieter(SAICSIT '17 Proceedings of the South African Institute of Computer Scientists and Information Technologists, 2017)
The Department of Basic Education in South Africa has identified certain problem areas in Mathematics of which the factorisation of numbers was specifically identified as a problem area for Grade 9 learners. The building ...
An alternative approach of estimating geohydrological parameters using the electrical resistivity method in investigating aquifer hydrological properties is presented in this research. The application of electrical resistivity ...
Abejide, O.S.; Mostafa, M.M.H.(IOP Conf: 2nd International Conference on Civil Engineering and Materials Science, 2017)
Considering the merits of road transportation in the economy and communication
activities of the modern societies, it is imperative to design a safe, stable, efficient and cost
effective road that will lead to increased ...
This study sought to identify the Key Performance Indicators (KPIs) for monitoring the implementation
performance of lean construction (LC) practices in South Africa. Given the limited penetration of the
LC concepts and ...
Democracy has been transformed by the introduction of ICT, which is
known as e-voting. E-voting is the use of computerised equipment to cast votes. Mvoting
is a subset of e-voting and is the use of mobile phones to cast ...
Mollo, Lesiba George; Emuze, Fidelis(West Africa Built Environment Research (WABER) Conference, 2017)
In most cases, the project team’s decision-making outcomes is criticized for failing to meet client needs when working with concrete task. The purpose of this study was to examine how Choosing by Advantages (CBA) would ...
Mollo, Lesiba George; Emuze, Fidelis; Fityoli, Lonwabo(ASOCSA. The Eleventh Built Environment Conference, At Durban, 2017)
The study investigated the influence of hidden lean practice in the
construction industry to develop methods, which can be used to lead lean
practice in the South African construction industry. Lean practice is
described ...
Makanda, Gilbert; Sypkens, Roelf(World Academy of Science, Engineering and Technology International Journal of Mathematical and Computational Sciences, 2017)
A mathematical model for knowledge acquisition in
teaching and learning is proposed. In this study we adopt the
mathematical model that is normally used for disease modelling
into teaching and learning. We derive ...
Makanda, Gilbert(4th International Conference of Fluid Flow, Heat and Mass Transfer, 2017)
Natural convection from a spinning sphere with temperature dependent viscosity, thermal conductivity and viscous dissipation was studied. A unique system of non-similar partial differential equations was solved using the ...
