Ontwerp van ’n transmissielyn-monteringsoplossing vir ’n onbemande vier-rotor helikopter
(AOSIS, 2014)A need exists for a transmission line monitoring system for use by Eskom to inspect transmission lines. A solution which uses a single board computer, visual and infrared cameras and a GPS module is described. Real-time ... -
Operational advantages of mobile refrigeration using a closed loop heat rejection configuration
(2018)The operational advantages of localised cooling, in particular moving the cooling source as close as possible to the area where cooling is required, has been investigated by different authors over a number of years. ... -
Optical variability modelling of newly identified blazars and blazar candidates behind Magellanic clouds
(Sissa Medialab, 2019)We present results of a variability study in the optical band of 44 newly identified blazar candidates behind the Magellanic Clouds. Our sample contains 27 flat spectrum radio quasars (FSRQs) and 17 BL Lacertae objects (BL ... -
Optimal passive optical network planning under demand uncertainty
(SATNAC, 2014)As a result of ever-increasing demand for access level bandwidth, long deployment cycles and the popularisation of more economically viable Point-to-Multipoint (P2MP) networks, service providers are moving to extensively ... -
Optimal switching-flux motor design and its cogging effect reduction
(IEEE, 2017)This paper presents an optimal switching-flux motor design in terms of cheap cost, simple manufacturing process, and easy maintenance. The high cogging effect and its impact on the performance of the machine is studied by ... -
Optimising of a domestic paraffin geyser for rural application
(IEEE, 2014)A water heating system based on paraffin was investigated. Such a system fulfils a need in rural areas where electrify is not available and solar geysers are not practical. The solution is particularly apt due to the ... -
Optimization of a residential heat pump system
(IEEE, 2019)With the constant increase in electrical energy costs in South Africa, households need to look at ways to either decrease their electrical energy usage or ways to supply their own electrical energy. This paper looks at the ... -
The optimized scheduling of a sanitary water heating system for commercial high rise apartment buildings
(IEEE, 2016)The installation of energy efficient water heaters in the residential and commercial sectors of South Africa have drawn much attention for more than a decade due to the energy crisis in South Africa. Most of the installations ... -
Overload Control Centre Bypass Detection System
(IEEE, 2014)Road transport is a significant economic necessity for freight movement in developing countries. The freight industry has a low profit margin resulting in overloading. As overloaded vehicles cause significant damage to ... -
An overview of the application of phasor measurement units (PMUs) and network coherent data in an interconnected power network: a case for Namibia
(Elsevier, 2017)This paper presents the technological background, the structure of a time-stamp for network coherent data and the emerging documentation on the data requirements for applications making use of network coherent data. ... -
An overview of the MHONGOOSE survey: observing nearby galaxies with MeerKAT
(Sissa Medialab, 2016)MHONGOOSE is a deep survey of the neutral hydrogen distribution in a representative sample of 30 nearby disk and dwarf galaxies with H I masses from ∼ 10 6 to ∼ 10 11 M , and luminosities from M R ∼ 12 ... -
The oxidative stress profile and its relation to vascular function in a bi-ethnic cohort: the SABPA study
(Karger, 2019)Oxidative stress and inflammation has been implicated in arterial stiffness, and hypertension development. Oxidative stress may interfere with normal vascular function by inactivation of NO and/or the production of ... -
PANGU (PAir-productioN Gamma-ray Unit): a high resolution gamma-ray space telescope
(Sissa Medialab, 2015) -
Particle-in-cell simulations of shear boundary layers in relativistic jets
(Sissa Medialab, 2018)The supermassive black holes in the centres of active galaxies (AGN) eject powerful relativistic jets which propagate over kpc scales, showing no significant momentum loss. Both observational evidence as well as theoretical ... -
PBI-blended membrane evaluated in high temperature SO2 electrolyzer
(ECS, 2018)It has been shown that hydrogen can be produced efficiently within the membrane based Hybrid Sulfur (HyS) process, where SO2 is electrochemically oxidized in the presence of H2O to produce H2 and H2SO4. In earlier studies, ... -
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 ... -
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 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 ... -
Perinatal insults and neurodevelopmental disorders may impact age of diagnosis of Huntington’s disease
