Failure prediction of critical mine machinery
(North-West University (South Africa), 2021)The South African mining industry is under immense economic pressure and has been following a negative trend over the last 30 years. It is thus imperative to regain a position at the front end of technological advances in ... -
Fault diagnostic system for predictive maintenance on a Brayton cycle power plant
(North-West University, 2004)Model-based fault detection and diagnostic systems have become an important solution (Munoz & Sanz-Bobi, 1998:178) in the industry for preventive maintenance. This not only increases plant safety, but also reduces down ... -
Fault identification and diagnosis for telephone exchange building facilities
(North-West University, 2005)Heating, ventilating and air conditioning (HVAC) systems consume 43 % of the energy used by buildings. This percentage grows when the HVAC system operates with malfunctions. Fault detection and diagnosis (FDD) methods ... -
The feasibility and application of multi–layer vacuum insulation for cryogenic hydrogen storage
(North-West University, 2011)A need was identified to test multi–layer vacuum super insulation (MLVSI) used in cryogenic applications for hydrogen storage. The study focuses on the application of commercially available MLVSI to a locally patented ... -
Feasibility of commercial maritime nuclear propulsion
(North-West University, 2009)The goal of this study is to make the unique benefits of modern nuclear technology available to a wider sphere. The basic hypothesis is that the time is ripe to re-investigate nuclear propulsion for commercial shipping. ... -
The feasibility of extraction of thorium and rare earths from monazite through a thermal plasma and a chemical treatment process
(North-West University (South Africa) , Potchefstroom Campus, 2017)Monazite is a chemically inert, rare earth phosphate mineral, which is difficult to process using conventional chemical digestive techniques. Monazite contains important commercial sources of thorium and lanthanides. The ... -
Feasibility of particle reinforcement in the casting of a ductile iron gate valve
(North-West University, 2018)The mining industry relies on gate valves to shut off flow in pipe systems. The demand for, specifically, ductile iron valve housings is steadily increasing in mining applications where cost, wear, and corrosion is a ... -
The feasibility of the manufacturing of a printed circuit type heat exchanger produced from graphite
(North-West University, 2009)The development of high temperature heat exchangers will play a vital part in the success of High Temperature Nuclear Reactors (HTRs). Manufacturing such heat exchangers from metals is becoming increasingly difficult as ... -
Feasibility of thorium extraction from a solid monazite matrix utilizing supercritical CO2 with TBP and HFA as chelates
(2014)With current energy demands globally and locally, nuclear energy remains one of the top competitors for cleaner and sustainable energy. The nuclear industry requires more inherent safety and proliferation resistance in ... -
A feasibility study of combining expert system technology and linear programming techniques in dietetics
(2014)Linear programming is widely used to solve various complex problems with many variables, subject to multiple constraints. Expert systems are created to provide expertise on complex problems through the application of ... -
Fermentation coupled with pervaporation : a kinetic study
(North-West University, 2011)Ethanol production through biomass fermentation is one of the major technologies available to produce liquid fuel from renewable energy sources. A major problem associated with the production of ethanol through fermentation ... -
Few group cross section representation based on sparse grid methods
(North-West University, 2012)This thesis addresses the problem of representing few group, homogenised neutron cross sections as a function of state parameters (e.g. burn-up, fuel and moderator temperature, etc.) that describe the conditions in the ... -
Fischer-Tropsch gas-to-liquids technology : an assessment of the competitive landscape
(North-West University, 2006)Global proven and speculative natural gas reserves are enormous. Unfortunately, much of these reserves is economically stranded and as a result, can not be profitably utilized using traditional methods. In another development, ... -
Fischer-Tropsch studies in the slurry phase favouring wax production
(North-West University, 1994)The Fischer-Tropsch synthesis over iron and cobalt based catalysts has been investigated in the slurry phase. Reaction conditions were restricted to those conducive for the optimum production of synthetic wax (i.e. high ... -
Fission product transport during pipebreaks in a PBMR confinement
(North-West University, 2010)The Pebble Bed Modular Reactor (PBMR) (Pty) Ltd Company intends to develop a demonstration power plant to be operated by the South African state owned utility Eskom. This demonstration plant will be a high temperature gas ... -
Flame treatment of polypropylene plastics within AK Stone Guards
(North-West University, 2008)Flame treatment of polypropylene is a polarization process which improves the adhesion qualities of the substrate (Kostyk, 2000). Flame treatment is known as a "Pre-Treatment" process and is widely used in industry to ... -
