Leaching of rare earth elements from bentonite clay
(The Southern African Institute of Mining and Metallurgy, 2012)Due to increasing concerns of global rare earth element shortfalls in the near future, possible alternative sources of rare earth elements have recently become of economic interest. One such alternative is decanting ... -
Lean implementation strategies: how are the Toyota Way principles addressed?
(Stellenbosch Univ, 2016)Lean manufacturing is widely considered to be a proven organisational improvement philosophy, yet the success rate of lean implementation in industry remains relatively low. Neglect of the human aspect of lean manufacturing ... -
A life cycle model for the development of airborne electronic equipment
(Univ Stellenbosch, 2017)This paper describes a life cycle model for the development of electronic equipment for use on board military aircraft in the South African context. The life cycle model presented consolidates the activities of systems ... -
Liminal presence of exo-microbes inoculating coconut endosperm waste to enhance black soldier fly larval protein and lipid
(Springer, 2020)The anaerobic decomposition of coconut endosperm waste (CEW), residue derived from cooking, has been insidiously spewing greenhouse gasses. Thus, the bioconversion of CEW via in situ fermentation by exo-microbes from ... -
Linear model of a closed three-shaft Brayton cycle
(IEEE, 2004)A linear model of a closed three-shaft Brayton cycle is developed. The model is intended to give an understanding of the dominant dynamic behavior in a nuclear power system that utilizes a closed three-shaft Brayton cycle. ... -
Linear model of a closed three-shaft Brayton cycle
(SAIEEE, 2006)A linear model of a closed three-shaft Brayton cycle at normal power operation is developed. The model is intended to give an understanding of the dominant dynamic behaviour in a nuclear power system ... -
Liquefaction of South African bituminous coal using phenol as a solvent
(International Pittsburgh Coal Conference, 2016) -
Liquid biofuels from food waste: current trends, prospect and limitation
(Elsevier, 2016)Depletion of fossil fuels, environmental damage due to pollution and energy security have intensified research on alternative liquid biofuels. A major portion of municipal solid waste is food waste. Huge quantities of food ... -
Load-shifting opportunities for typical cement plants
(ERC (Energy Research Centre), 2013)Investigations into demand side reductions have been encouraged by the South African electricity utility, Eskom, in sectors with high electricity consumption, such as the cement industry. The South African cement ... -
Local benchmarking in mines to locate inefficient compressed air usage
(Elsevier, 2019)Compressed air is a vital source of energy for deep mines. It is therefore alarming that leaks, wastages, and losses are the highest contributing factors to the deterioration of compressed air network efficiency. However, ... -
A low cost circularly polarized microstrip patch antenna with low axial ratio for UHF RFID applications
(IAMOT, 2020)This paper presents a low cost circularly polarized microstrip patch antenna with low axial ratio (AR) and broad AR beam width for ultrahigh frequency (UHF) radio-frequency identification (RFID) applications. The ... -
Low cost hydrogen production by anion exchange membrane electrolysis: a review
(Elsevier, 2018)Anion exchange membrane (AEM) water electrolysis is a hydrogen production method that is achieved with an AEM, using electricity. One of the major advantages of AEM water electrolysis is the replacement of conventional ... -
A low-cost condition monitoring solution for industrial bakery equipment
(NWU, 2018)Artisanal bakeries perform a critical function in many societies all over the world. However, artisanal bakers struggle to compete with commercial bakeries’ efficiencies due to the lack of technology deployment. One aspect ... -
Low-cost monitoring of partial discharge activity by means of Sub-Nyquist sampling
(British Institute of Non-Destructive Testing, 2014)The relatively low cost of distribution transformers dictates that the cost of any condition monitoring system for such transformers should be as low as possible. Premature failure of any transformer in an electrical grid ... -
Low-profile vertical polarized slotted antenna for on-road RFID-enabled intelligent parking
(IEEE, 2020)A low-profile vertical polarized antenna is presented for radio frequency identification (RFID)-enabled intelligent parking system applications. In order to reduce the crosstalk between antennas and false detection of ... -
LQ control for coordinated linear systems
(IEEE, 2014)Coordinated linear systems are a special class of hierarchical linear systems, with a strict top-to-bottom information structure. The LQ problem over all structure-preserving static state feedbacks is discussed. The ... -
LTI modelling of active magnetic bearings by means of system identification
(SAIEE Publications, 2011)A relatively unknown phenomenon in active magnetic bearings (AMBs) is that the frequency content of their rotor position signal can induce nonlinear behaviour in the bearings. The existence of such frequency-induced nonlinear ... -
The Lwazi Community Communication Service: design and piloting of a voice-based information service
(World Wide Web Conf. (WWW 11), 2011)We present the design, development and pilot process of the Lwazi Community Communication Service (LCCS), a multilingual automated telephone-based information service. The service acts as a communication and dissemination ... -
Magnetic circuit analysis of the low-cost in-wheel switching flux motor for HEV applications
(IEEE, 2019)This paper presents the design and analysis of Permanent Magnet Switching Flux Motor (PMSFM) for hybrid electrical vehicle application. The design is intended to obtain a cost effective, efficient motor with small flux ...
