Designing a new methodology for customs risk models
(CCES, 2019)Effective risk management is a prerequisite to find an acceptable balance between the objectives of a customs operation and the streamlined flow of goods. The customs operations in many developing countries are characterised ... -
Destabilization dynamics of clay and acid-free polymers of ferric and magnesium salts in AMD without pH adjustment
(IWA Publishing, 2016)The physicochemical treatment was employed to treat acid mine drainage (AMD) in the removal of turbid materials using clay only (exp A) and a combination of clay, FeCl3 and Mg(OH)2 (exp B) to form a polymer. A 5 g sample ... -
Destoning of fine coal in a fluidized bed
(Springer, 2016)Water scarcity is driving the development of dry coal beneficiation processes. A lot of research has gone into the development of dry dense medium fluidized bed technology (DMFB), especially in China. However, these processes ... -
Detailed characteristics of coal ash from the largest coal-fired power plant in South America
(Swanson School of Engineering, Univ of Pittsburgh, 2015) -
Detailed characterization of SA high mineral matter inertinite–rich coals and density fractions and effect on reaction rates with carbon dioxide: macerals, microlithotypes, carbominerites and minerals
(SAIChE, 2013)An investigation was undertaken to determine the distribution of macerals and minerals in South African Highveld coal deposits as well as density fractions derived from a typical deposit. The corresponding effects on ... -
Determination and the no-free-lunch paradox
(MIT Press, 2011)We discuss the no-free-lunch NFL theorem for supervised learning as a logical paradox—that is, as a counterintuitive result that is correctly proven from apparently incontestable assumptions. We show that the uniform prior ... -
Determination of mineral matter and elemental composition of individual macerals in coals from Highveld mines
(SAIMM, 2016)A number of conventional and advanced analytical techniques (proximate and ultimate analysis, low-temperature oxygen-plasma ashing, X-ray diffraction, X-ray fluorescence spectrometry, coal petrography, and light-element ... -
Developing a full core model of the North Anna Reactor using SCALE 6.2.3, NESTLE and MCNP 6.2
(North West University, 2022)This study presents the development of the modelling for a T-NEWT/NESTLE* lattice-to-nodal diffusion calculation. The reactor selected for this study is the North-Anna (NA) Unit 1 Pressurized Water Reactor (PWR) of the ... -
Developing a full-core MCNP6 and RELAP5 model of the European pressurized reactor using NWURCS
(Taylor & Francis, 2018)The European pressurized reactor (EPR) is classified as a Generation III+ reactor. It differs from a conventional pressurized water reactor in many aspects, one of which is the core design. This evolutionary reactor lends ... -
Developing esco procedures for large telecommunication facilities using novel simulation techniques
(Energy Research Centre, University of Cape Town, 2008)Peak electricity demand in South Africa will exceed the available operational generation capacity in 2007. The state utility, Eskom, is addressing this challenge, inter alia, with the implementation of a national Demand-side ... -
Developing skills for neutronic modelling of nuclear power reactors in South Africa
(2016)In recent years, due to economic and social infrastructure development and growth, South Africa has been facing growth in energy demand. Addressing this demand includes building more coal power stations, however with ... -
Development and implementation of an advanced mobile data collection system
(SAIIE, 2016)This paper describes the development and implementation of a generic data collection tool. The Mobile Information Collection and Verification System (MICAVS) provides users with a generic platform to create application ... -
Development of a controller for fuel cell and supercapacitor application
(CATSA (Catalysis Society of South Africa), 2014)The growing demand for energy in the world causes a lot of pressure to the environment and the resources used to supply the energy. To ensure a continuous, more reliable and environmentally friendly energy supply system ... -
The development of a flexible rotor active magnetic bearing system
(SAIEEE, 2007)A design process comprising aspects of modelling and analysis is developed, implemented and verified for a flexible rotor active magnetic bearing system. The system is specified to experience the first three critical ... -
Development of a low purity aluminum alloy (Al6082) anodization process and its application as a platinum-based catalyst in catalytic hydrogen combustion
(Elsevier, 2020)In this study, we present a process to prepare a Pt/anodized aluminum oxide (AAO) catalyst for catalytic hydrogen combustion applications using low cost and low aluminum (Al) purity Al6082 alloy (97.5% Al) as the substrate. ... -
Development of a model for road transport fuel management
(SAIIE, 2016)Road transport is responsible for 76% of cargo movement in South Africa; at the same time transport cost in Sub-Sahara Africa forms a much higher fraction of the total cost of landed goods compared to the rest of the world. ... -
Development of a predictive pole-slip protection function for synchronous generators
(IEEE, 2015)Predictive pole-slip protection is not implemented in commercially available protection relays, since complex modeling of the network and generator is required to do such predictive detection. All pole-slip protection ... -
Development of a Pt/stainless steel mesh catalyst and its application in catalytic hydrogen combustion
(Elsevier, 2019)In this paper, different methods to prepare a Pt/stainless steel mesh catalyst for catalytic hydrogen combustion are reported. Pt was deposited as a thin layer onto stainless steel mesh as a support matrix. Thermal treatment ... -
Development of a quadcopter for power line inspection
(2014)The inspection of transmission lines is to be done annually. It is proposed that a quadcopter is used to do the inspection of these transmission lines. The modelling of the quadcopter was done by studying its physical ... -
