Stride and translation invariance in CNNs
(Southern African Conference for Artificial Intelligence Research, 2020)
Convolutional Neural Networks have become the standard for image classification tasks, however, these architectures are not invariant to translations of the input image. This lack of invariance is attributed to the use of ...
Tracking translation invariance in CNNs
(Southern African Conference for Artificial Intelligence Research, 2020)
Although Convolutional Neural Networks (CNNs) are widely used, their translation invariance (ability to deal with translated inputs) is still subject to some controversy. We explore this question using translation-sensitivity ...
Unsupervised Fine-tuning of Speaker Diarisation Pipelines using Silhouette Coefficients
(SACAIR, 2021)
We investigate the use of silhouette coefficients in cluster analysis for speaker diarisation, with the dual purpose of unsupervised fine-tuning during domain adaptation and determining the number of speakers in an audio ...
Co-pyrolysis of coal and raw/torrefied biomass: a review on chemistry, kinetics and implementation
(Elsevier, 2021)
Thermochemical conversion via co-pyrolysis has the potential to be an efficient route for converting biomass to
bio-energy and bio-refinery products. In this review, the implementation of co-pyrolysis of torrefied biomass ...
Modelling nanoparticles parameters for antimicrobial activity
(Springer, 2020)
The current study reveals the antimicrobial activity of various nanoparticles (NPs) against numerous microorganisms through statistical models that define suitable parameters to improve the antimicrobial efficacy of NPs. ...
Mercury removal by porous sulfur copolymers: adsorption isotherm and kinetics studies
(Elsevier, 2020)
Mercury is one of the most toxic, harmful element present in water that severely affects human health. Many traditional as well as advanced technologies were developed to remove mercury from wastewater. In this study, ...
Electrical resistivity of carbonaceous bed material at high temperature
(Springer Verlag, 2020)
This study reports the effect of high-temperature treatment on the electrical properties of charcoal, coal, and coke. The electrical resistivity of industrial charcoal samples used as a reducing agent in electric arc ...
Investigation of structural and optical properties of biosynthesized Zincite (ZnO) nanoparticles (NPs) via an aqueous extract of Rosmarinus officinalis (rosemary) leaves
(Cambridge Univ Press, 2020)
Biosynthesized Zincite nanoparticles have been successfully demonstrated by a completely green process mediated aqueous extract of rosemary leaves acting as both reducing and stabilizing agents and zinc nitrate hexahydrate ...
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. ...
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) ...
