A qualitative assessment of the insulation systems of medium voltage induction motors
(IEEE, 2007)The research was an attempt to understand the condition of the insulation system and to classify the data according to its condition. Data mining processes was used to create a model to gain insight into the data and the ... -
Quality of supply data mining
(IEEE, 2014)Extracting useful network management information from a large volume of QoS data obtained all over a network can be simplified by innovative data mining techniques. The need for QoS expertise is reduced as interactive ... -
Quality research management improves design research effectiveness
(Univ Stellenbosch, 2019)Design research projects are often more complex than initially perceived due to a requirement for novelty, the creativity inherent in the design process, and the limited experience of novice researchers. Also, expectations ... -
Quantification of optimal electricity cost risk reduction for a South African gold mining company
(IEEE, 2014)Electricity cost risks such as carbon tax, ECS and unavoidable tariff increases threaten the financial wellbeing of South African gold mines. Some of these proposed cost risks are however not enforced as yet. However, once ... -
A quantitative model to evaluate post-implementation efficiency of Scrum
(IOS Press, 2010)In order to improve the information system development process many companies have adopted system development methodologies. Various evaluation methods and frameworks exist in the literature to assist companies during their ... -
Radio frequency interference detection using machine learning
(IEEE, 2016)Radio frequency interference (RFI) has plagued radio astronomy which potentially might be as bad or worse by the time the Square Kilometre Array (SKA) comes up. RFI can be either internal (generated by instruments) or ... -
Re-evaluation of the separation parameters based on the Berman-Olander long-bowl gas-centrifuge solution
(SAAM, 2014)The hydrodynamic equations for a long-bowl gas-centrifuge can be simplified to obtain a one-dimensional differential equation for the variation of the non-dimensional axial velocity in the radial direction. This equation ... -
Real-time monitoring of temperature distribution in a lithium-ion battery pack
(NWU, 2018)Intelligent battery management systems aim to continuously diagnose the state-of-health (SOH) of cells in a battery pack and predict performance, reliability and safety issues. Cells with a higher internal resistance ... -
Real-time power system oscillation monitoring using synchrophasor measurements
(IEEE, 2015)Inter-area oscillations impact negatively on power system stability and power transfer capability. Monitoring oscillations in real time can improve control of the power system. Synchrophasor data from Phasor Measurement ... -
Received power prediction of a terrestrial TV broadcasting transmitter using ordinary kriging interpolation
(SATNAC, 2014)Radio Environment Mapping (REM) provides information useful for many different applications in the telecommunications field. In this paper, the authors evaluate the ability of ordinary kriging (OK) to produce a REM ... -
Reconfiguring mining compressed air networks for cost savings
(IEEE, 2014)The ever-growing human population, limited energy resources and the effect of greenhouse gas emissions have become major global concerns for the energy sector. This includes the electricity generation sector. This dilemma ... -
Reducing DLOFC fuel temperatures by mixing thorium with LEU in a single-zone six-pass fuel cycle in a PBMR-DPP-400 core
(ANS (American Nuclear Society), 2016)Many studies have been done in neutronics and thermal-hydraulic simulation of the standard 6-pass fuel recirculation scheme for the standard 9.6 wt % enriched, 9 g per fuel sphere low-enriched uranium (LEU) fuel in the ... -
Reducing energy consumption of mine cooling systems by controlling chilled water demand of mobile cooling units
(IEEE, 2014)Energy costs are increasing rapidly. Energy efficiency strategies are required to reduce electricity consumption for energy intensive operations. Cooling systems of deep level mines consume approximately 25% of their total ... -
Reducing the communication costs of a remote monitoring and maintenance system for an energy services company (ESCo)
(SAIIE, 2016)Demand-Side Management (DSM) initiatives can result in substantial electricity cost reductions. Energy Service Companies (ESCos) typically perform remote monitoring and maintenance to ensure sustained performance of these ... -
Reduction of salinity of water using acrylamide-based polyampholyte
(EARET, 2018)Polyampholytes are charged macromolecules, which carry both acidic and basic groups. These groups dissociate, leaving ions on chains and counter ions in solution, under appropriate conditions, ... -
A reflective practice approach for supporting IT skills required by industry through project-based learning
(Springer, 2019)This paper reflects on the concerns that IT graduates lack specific skills required in industry and how project-based learning (PBL) can support these skills. An overview of the instructional design of a course module ... -
Reflective team meetings: a learning experience for first-year engineering students in joint projects
(IEEE, 2018)The aim of this research was to report on reflective team meetings as a learning experience for first-year engineering students in joint projects. To some extent, working in joint projects is new to first-year students ... -
Regenerator for Varshamov-tenengolts-like synchronisation error correcting codes
(IEEE, 2008)Synchronisation errors, that is, the insertion of additional or deletion of valid symbols, are the most difficult class of errors to correct - containing the class of additive errors as a subset. A regenerating algorithm, ... -
THE RELATIONSHIP BETWEEN CONTEXTUAL FACTOR AND SERVICE DELIVERY PERCEPTIONS IN A MAJOR CITY IN SOUTH AFRICA
(IBC, 2021)South African municipalities have in recent times been piqued with unprecedented service delivery protests, indicative of a failure to provide these amenities as expected. With soaring levels of unemployment and ...
