Machine learning for radio frequency interference mitigation using polarization
(IEEE, 2017)Radio frequency interference (RFI) is electromagnetic interference (EMI) from signals in the radio frequencies of the electromagnetic spectrum. RFI reduces the sensitivity of radio telescope and produces artefacts in ... -
Magnetic circuit analysis of the low-cost in-wheel switching flux motor for HEV applications
(IEEE, 2019)This paper presents the design and analysis of Permanent Magnet Switching Flux Motor (PMSFM) for hybrid electrical vehicle application. The design is intended to obtain a cost effective, efficient motor with small flux ... -
Manufacturing of briquettes from typical highveld coal fines using various binders
(Swanson School of Engineering, Univ of Pittsburgh, 2015) -
A mathematical ranking model in learning analytics
(CMMSE, 2016)The introduction of new educationa l trends triggers the development of innovative methods to collect, analyse and report the data subsequently generated. This paper discusses the implementation of a ... -
Measurement and verification baseline development and service level adjustments for fridge plant systems
(2009)In this article the authors provide an overview of a fridge plant system and discuss the data requirements and data selection for baseline development. The baseline development is divided into two scenarios: 1) where ... -
Measurement and verification of the Eskom irrigation pumping standard product programme
(2013)Eskom Integrated Demand Management (IDM) initiated a funding mechanism termed the Standard Product Programme (SPP) to cater for smaller Energy Efficient (EE) projects. The impacts of these projects also need to be assessed ... -
Measurement and verification of the Eskom irrigation pumping standard product programme: evaluation of crop load factors
(2013)Eskom Integrated Demand Management (IDM) also included irrigation in the Standard Product Programme (SPP) to cater for smaller irrigation Energy Efficient (EE) projects. The irrigation sector is a large energy consumer ... -
Measurement uncertainty of current harmonics during the assessment of compliance to grid code requirements
(IEEE, 2018)This paper improves the impact of measurement uncertainty on harmonic grid code compliance assessment by characterization of the current transformers at a renewable power producer. Field data was collected to evaluate the ... -
The MeerKAT Fornax survey
(Sissa Medialab, 2016)We present the science case and observations plan of the MeerKAT Fornax Survey, an H I and radio continuum survey of the Fornax galaxy cluster to be carried out with the SKA precursor MeerKAT. Fornax is the second most ... -
The MeerKAT international GHz tiered extragalactic exploration (MIGHTEE) survey
(Sissa Medialab, 2016)The MIGHTEE large survey project will survey four of the most well-studied extragalactic deep fields, totalling 20 square degrees to μ Jy sensitivity at Giga-Hertz frequencies, as well as an ultra-deep ... -
A MeerKAT view on galaxy clusters
(Sissa Medialab, 2016)Almost two decades of observations of radio emission in galaxy clusters have proven the existence of relativistic particles and magnetic fields that generate extended synchrotron emission in the form of radio halos. In the ... -
Meeting Students’ Expectations of Blended Learning
(Research Association for Interdisciplinary Studies, 2020)Blended learning as a mode of delivery is widespread in universities. It has gained even more prominence during the Covid-19 pandemic. Most educational programs in many countries had to be adapted abruptly to remote ... -
Membranes with recombination catalyst for hydrogen crossover reduction: water electrolysis
(ECS, 2018)An unusual morphology of the Pt-based catalyst, embedded in a PFSA membrane matrix, is described. The catalyst was developed for reducing hydrogen gas crossover in the PEM water electrolysis process. A modified electroless ... -
Metabolomics and personalized medicine
(Elsevier, 2016)Current clinical practice strongly relies on the prognosis, diagnosis, and treatment of diseases using methods determined and averaged for the specific diseased cohort/population. Although this approach complies positively ... -
Metal ions adsorption affinity of clayey materials from the North West Province of South Africa
(CUMTP, 2014)Local clays that are abundant in the periphery of Potchefstroom in South Africa were characterized and investigated as potential sorbents for the removal of metal ions from effluents. The clay samples mostly contained ... -
Methodological variables in the analysis of cell-free DNA
(Springer, 2016)In recent years, cell-free DNA (cfDNA) analysis has received increasing amounts of attention as a potential non-invasive screening tool for the early detection of genetic aberrations and a wide variety of diseases, especially ... -
A methodology to determine best-suited waiting-time periods for turbine start-up under fluctuating resources
(IEEE, 2019)— It is not uncommon for engineering process plants to comprise energy recovery. When power generation takes place under such circumstances, the nature of interlinked processes may result in fluctuating resource availability. ... -
Microgrid energy management through levelized cost of energy metric
(IEEE, 2020)The abundance of solar energy in Africa provides the ideal opportunity to mitigate the concerns on price, reliability and voltage quality of electricity supply to end-users. Rooftop PV and local energy storage solutions ... -
The millisecond pulsar contribution to the rising positron fraction
(Sissa Medialab, 2016)Pair cascades from millisecond pulsars (MSPs) may be a primary source of Galactic electrons and positrons that contribute to the increase in positron flux above 10 GeV as observed by PAMELA and AMS−02. The Fermi Large ... -
Mineralogical observation made during the kinetic dissolution study of chalcopyrite mineral in sulphate media under free pH at room temperature
