(CRC Press, 2015)An ever-increasing dependence on green energy has brought on a renewed interest in polymer electrolyte membrane (PEM) electrolysis as a viable solution for hydrogen production. While alkaline water electrolyzers have been ... -
PEM water electrolysis: preliminary investigations using neutron radiography
(Elsevier, 2017)The quasi-dynamic water distribution and performance of a proton exchange membrane (PEM) electrolyzer at both a small fuel cell's anode and cathode was observed and quantitatively measured in the in-plane imaging geometry ... -
Performance analysis of a multilingual directory enquiries application
(Pattern Recognition Association of South Africa and Mechatronics International Conference, 2014)In a multilingual society such as South Africa, a practical directory enquiries (DE) application should be able to serve users from various language backgrounds with information relating to names in various languages: ... -
Performance analysis of a permanent magnet transverse flux generator with double coil
(IEEE, 2016)One of the disadvantages of permanent magnet (PM) transverse flux machines is high magnetic flux leakage in the stator and rotor cores. To improve the magnetic circuit of this class of machines, a generator with double ... -
Performance evaluation and emissions reduction of a micro gas turbine via the co-combustion of H2/CH4/CO2 fuel blends
(Elsevier, 2020)Worldwide energy supply is rapidly shifting towards more sustainable and cleaner power generation technologies including solar PV, wind turbines and natural gas. The co-combustion of fuel blends, consisting of renewably-generated ... -
Performance evaluation and kinetic modeling of down-flow high-rate anaerobic bioreactors for poultry slaughterhouse wastewater treatment
(Springer, 2020)In this study, the treatment of poultry slaughterhouse wastewater (PSW) was evaluated using two new down-flow high-rate anaerobic bioreactor systems (HRABS), including the down-flow expanded granular bed reactor (DEGBR) ... -
Performance evaluation of a high-throughput microchannel reactor for ammonia decomposition over a commercial Ru-based catalyst
(Elsevier, 2015)In this work, the prospect of producing hydrogen (H2) via ammonia (NH3) decomposition was evaluated in an experimental stand-alone microchannel reactor wash-coated with a commercial Ruthenium-based catalyst. The reactor ... -
A performance evaluation of a microchannel reactor for the production of hydrogen from formic acid for electrochemical energy applications
(ESG, 2018)An experimen tal evaluation of a microchannel reactor was completed to assess the reactor performance for the catalytic decomposition of vaporised formic acid (FA) for H2 production. Initially, X-ray ... -
The performance of feature-based classification of digital modulations under varying SNR and fading channel conditions
(IEEE, 2017)Feature-based classification is a method used for automatic modulation classification of communication signals. This method requires extraction of various features from a signal. One of the approaches for feature extraction ... -
Performance of various cyanide degrading bacteria on the biodegradation of free cyanide
(EARET, 2018)This study reports on the biodegradation of free cyanide (FCN) by cyanide degrading bacteria (CDB) that were isolated from mining wastewater and in thiocyanate containing wastewater. The performance of these isolates ... -
Performance of various cyanide degrading bacteria on the biodegradation of free cyanide in water
(Elsevier, 2019)This study reports on the biodegradation of free cyanide (FCN) by cyanide degrading bacteria (CDB) that were isolated from mining wastewater and thiocyanate containing wastewater. The performance of these isolates was ... -
Performance visualisation of a transcritical CO2 heat pump under fault conditions
(NWU, 2018)Heat pump systems have gained acceptance and appeal as an energy efficient alternative to electrical geysers for the purpose of water heating. This paper investigates a next-generation transcritical heat pump system using ... -
Perishable produce temperature profiling using intelligent telematics
(SATNAC, 2014)Controlling, monitoring and maintaining the temperature of agricultural products in the cold chain is critical to avert the ills associated with this industry. The various segments of the cold chain not only require ... -
