Benign interpolation of noise in deep learning
(South African Institute of Computer Scientists and Information Technologists, 2020)The understanding of generalisation in machine learning is in a state of flux, in part due to the ability of deep learning models to interpolate noisy training data and still perform appropriately on out-of-sample data, ... -
Bentonitc clay adsorption affinity for anionic and cationic dyes
(PSRC, 2014)The incidence of dye pollution in South Africa is quite alarming, requesting effective and affordable techniques to curb further degradation of the limited water resource. Adsorption is an attractive technique due to a ... -
Bilateral G2P accuracy: measuring the effect of variants
(Pattern Recognition Association of South Africa and Mechatronics International Conference, 2017)Incorporating pronunciation variants in a dictionary is controversial, as this can be either advantageous or detrimental for a speech recognition system. Grapheme-tophoneme (G2P) accuracy can help guide this decision, ... -
Bio-butanol fermentation using clostridium acetobutylicum and clostridium tetanomorphum in modified bioreactor flasks
(ETA-Florence Renewable Energies, 2015)An alternative new generation biofuel to bio-ethanol has attracted researchers to investigate various approaches for optimization of traditional ABE fermentation to enable bio-butanol to be produced cheaper at an industrial ... -
Bio-oil and bio-char production from sunflower hulls
(ETA-Florence Renewable Energies, 2011)In this paper, the hydrothermal liquefaction of sunflower hulls into biooil and biochar is presented. The main manipulated variables that were studied were biomass load, catalyst type and temperature. The experimental ... -
Bio-oil production from sweet sorghum bagasse via liquefaction using alkaline solutions and identification of phenolic products
(Springer, 2020)The feasibility of converting biomass into bio-oil and the effect of an alkaline treatment during biomass liquefaction was studied. Sweet sorghum bagasse (SSB) was treated with NaOH concentrations of 0.5, 1.0, 3.0 and 6.0 ... -
Bioethanol from cassava for a community project
(ETA-Florence Renewable Energies, 2010)Although the North-West Province of South Africa is renowned for its platinum industry, wildlife tourism and Casino resorts, its people are among the poorest in South Africa. The Thusanang community project concept was ... -
Biofuel production from spent coffee grounds via lipase catalysis
(Taylor & Francis, 2018)Lipases namely Mucor miehei, Pseudomonas cepacia, Rhizopus delemar, Geotrichum candidum, Candida rugosa, Porcine pancreas-II, Pseudomonas fluorescence, and Candida antarctica lipase-B (Novozyme-435) were employed for ... -
Biofuels from spent coffee grounds: comparison of processing routes
(Taylor & Francis, 2020)Bulk fuel was produced from spent coffee grounds (SCG) using different oil extraction and fuel production methods. The highest oil yield (30.2%) and energy efficiency (50%) from continuous hydrothermal liquefaction (CHTL) ... -
Biological reduction of COD and sulphate by SRB in anaerobic moving bed biofilm reactor under high metal loading conditions
(EARET, 2018)The performance of an anaerobic moving bed biofilm reactor (MBBR) containing AnoxKaldnesTM K5 model for the treatment of raw acid mine drainage (AMD) was investigated for the reduction of sulphate and chemical oxygen ... -
Biosorption of cadmium from water using surfactant impregnated eggshell
(EARET, 2018)Cadmium (Cd) is regarded as one of the most toxic elements and it causes water pollution when it exceeds the permissible limit. It is currently present in the Mooi River above these permitted levels, and must therefore ... -
Biosorption of Fe (II) from aqueous solution by brewing waste: equilibrium and kinetic studies
(Japan Society on Water Environment, 2019)The physicochemical analysis of surface water of Mooi and Vaal rivers network indicated that the concentration of iron was far above the required limit by the South Africa water regulation. In this study, brewing waste was ... -
Block RAM implementation of a reconfigurable real-time PID controller
(IEEE, 2012)Despite the numerous advantages reconfigurable computing adds to a system, it is only advantageous if the execution time exceeds the configuration time. As a result of the long configuration time, reconfiguration is only ... -
Block RAM-based architecture for real-time reconfiguration using Xilinx® FPGAs
(South African Institute of Computer Scientists and Information Technologists, 2015)Despite the advantages dynamic reconfiguration adds to a system, it only improves system performance if the execution time exceeds the configuration time. As a result, dynamic reconfiguration is only capable of improving ... -
Bottom of Pyramid 4.0: modularising and assimilating industrial revolution cognition into a 4-tiered social entrepreneurship upliftment model for previously disconnected communities
(World Scientific, 2018)Developing a sociopreneurial (social-entrepreneurship) ecosystem is a substantial long-term investment. Much like natural ecosystems, there are a multitude of support systems needed to maintain balance and diversity in ... -
Brewery effluent sludge characterization and dewatering to increase potential water recycling capabilities
(EARET, 2018)In this study various coagulants and flocculants were tested for optimum removal of COD from brewery wastewater. The coagulants used were ferric chloride and an organic coagulant mixture obtained from the brewery company. ... -
The carbon dioxide gasification characteristics of biomass char samples and their effect on coal gasification reactivity during co-gasification
(Elsevier, 2018)The carbon dioxide gasification characteristics of three biomass char samples and bituminous coal char were investigated in a thermogravimetric analyser in the temperature range of 850–950 °C. Char SB exhibited higher ... -
The carbon dioxide, methane and nitrogen high-pressure sorption properties of South African bituminous coals
