Ultimate load and deflection behaviour of cellular beams.
(2001)Cellular beams were developed in 1987 and are an adaptation of castellated beams having many of the same advantages and disadvantages. There are no published results of tests on cellular beams and there is only one ... -
Understanding flow structure in a groyne field.
(2018)Groyne structures are widely used all over the world for the purposes of controlling longshore currents and slowing down the rate of sediment transport along coast lines. The limited previous studies in this area have led ... -
A universal method for assessing intrinsic expansiveness of soils.
(2004)Many of the attempts made over the past six decades to find a universal system for assessing expansiveness of soils using soil index data have failed to follow the basic principles of soil mechanics. By overcoming most ... -
Urban poverty reduction through municipal solid waste management (MSWM) : a case study of Maseru and Maputsoe in Lesotho.
(2002)The study was designed to generate data and information necessary for designing an appropriate sustainable solid waste management system, and examining the socio-economic benefits of urban municipal so lid waste management ... -
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. -
Use of multi-criteria decision analysis integrated with GIS and air pollution model inputs for schools site selection.
(2019)Schools site selection is an essential process which needs knowledge of different fields. The process involves scientific justification, judgment and a finding of suitable land, which consider financial, social, ecological ... -
The use of small scale hydroelectric power in South Africa, hydro and economic potential for rural electrification.
(2012)Small hydro generation refers to generating capacity of less than 10 MW with the most common being Run-of-River. In South Africa, the level of rural electrification is approximately 50 percent with most of the energy ... -
Weight optimization for hybrid, multi-scale CNT/fibre reinforced composite laminates.
(2021)In this study, an investigation on an optimal lightweight design of a 3-phase CNT/fibre reinforced nanocomposite plate was conducted, subject to a frequency constraint. The design variables for the optimization process ... -
Wind driven waves and re-suspension dynamics in shallow lakes : St. Lucia, South Africa.
(2014)Abstract available in PDF file. -
Wind induced sediment re-suspension in a shallow lake.
(2011)Wind induced turbidity within shallow lakes can greatly affect the biological functioning of a system in either a positive or negative manner. This research aims to understand and model the physical processes that cause ...
