Considering the influence of human trust in practical social engineering exercises
(IEEE, 2014)There are numerous technical advances in the field of information security. However, the application of information security technologies alone is often not sufficient to address security issues. Human factors play an ... -
Constraining the dark matter density in galaxy clusters
(PoS, 2015)We illustrate the potential of using stellar velocity dispersion profiles of brightest cluster galaxies (BCGs), in combination with X-ray and weak-lensing derived cluster mass profiles, to constrain the matter distribution ... -
Constraining the environment of neutrino-emitting regions in jets of FSRQs
(Sissa Medialab, 2019)Recently, the gamma-ray blazar TXS 0506+056 has been proposed as the source of neutrino events detected by IceCube in 2014-15 and 2017. This has further pushed the idea of blazar jets being among those cosmic sites where ... -
Constraining viewing geometries of pulsars with single-peaked γ-ray profiles using a multiwavelength approach
(SAIP, 2011)Since the launch of the Large Area Telescope (LAT) on board the Fermi spacecraft in June 2008, the number of observed γ-ray pulsars has increased dramatically. A large number of these are also observed at radio frequencies. ... -
Constraints on the lepton content of PWN from the local CR positron spectrum
(ICRC, 2008)Geminga is a nearby pulsar with an age of 3.42×105 yr and a spindown power of 3.2×1034 erg/s at present. B0656+14 has comparable spindown power, with an age of 1.11×105 yr and a distance of 290 pc. The winds of these ... -
Continuous harmonic impedance assessment using online measurements
(IEEE, 2015)The quantification of harmonic emission requires an accurate representation of the network harmonic impedances. A number of techniques have been proposed to make the assessment of the network harmonic impedances practical ... -
A control algorithm approach for optimizing energy resources through power generation for a South African steel works plant
(SAIIE, 2014)Numerous engineering plants have varieties of processes, where individual process flows are dependent on previous processes and operated by default or manual settings. Initial raw material feeds may fluctuate over time, ... -
Control of magnetically suspended rotor combined with motor drive system
(IFAC, 2014)This paper presents the cooperative control between the active magnetic bearing system and the permanent magnet synchronous drive. More specifically, the coupling between the vibration control and sensorless drive control ... -
The cost effects of DSM interventions on vertical roller mills in the cement industry
(IEEE, 2014)Load management is a successful way to implement evening load reduction and load shift DSM projects on cement plants. However, finishing grinding in the cement production process requires accurate temperature control. To ... -
Cost savings on mine dewatering pumps by reducing preparation- and comeback loads
(IEEE, 2014)With the introduction of a time-of-use (TOU) tariff structure by Eskom, the implementation of projects that shift load from peak TOU times to times of the day when electrical energy is less expensive has increased. To ... -
CREAK descriptor evaluation for visual odometry
(IEEE, 2019)Each year, latest state of the art technologies and algorithms arise that claim and prove to-shine their predecessors. One such algorithm is the Colour-based Retina Key-point (CREAK) descriptor, which is based on the FAST ... -
CTA 102 - Year over year receiving you
(Sissa Medialab, 2019)The FSRQ CTA 102 (z=1.032) has been tremendously active over the last few years. During its peak activity lasting several months in late 2016 and early 2017, the gamma-ray and optical fluxes rose by up to a factor 100 ... -
CUSTOMERS’ BRAND AWARENESS, BRAND TRUST, AND BRAND LOYALTY FOR PRIVATE LABEL BRANDS IN SOUTH AFRICA.
(IBC, 2021)Private label brands have over the years gained insurgence in the grocery retail sector, creating opportunities for grocery retailers to increase variety in product off erings for their customers. ... -
Cyber Security disclosure in the banking sector: A case of South Africa and China
(IBC, 2022)This study compares risk reporting, specifically cyber risk reporting, between South Africanand Chinesebanks.Major corporate scandals had significant impacts on the economic environmentand has led to an ... -
Data acquisition system for capturing dynamic transients in a control valve
(IEEE, 2004)This work presents the development of a data acquisition (DAQ) system to be used in conjunction with fuzzy modelling to derive a dynamic mathematical model of a control valve. Characterising the behaviour of a control valve ... -
Data logger and companion application for time-of-use electricity
(IEEE, 2018)Electricity generation is becoming more expensive, hence Time-of-Use (ToU) electricity tariff structures, such as Eskom Megaflex are implemented. The companion application is an integrated solution designed for use with ... -
Data mining: a technique used to extract information from tan delta measurements on medium voltage induction motors
(IEEE, 2007)The study attempted to understand the condition of the insulation system and to classify the data according to its condition. Data mining processes were used to gain insight into the data and the condition of the insulation ... -
DC power quality emulator
(IEEE, 2020)Currently, no dc power quality standards exist. The lack of dc power quality (PQ) standards can be addressed by, amongst others, evaluating the impact of PQ deviations on consumer end equipment. A voltage disturbance ... -
Dc-bus voltage balancing controllers for split dc-link four-wire inverters and their impact on the quality of the injected currents
(IET, 2017)The increasing share of single-phase distributed generation units in low-voltage grids causes voltage unbalance problems and overvoltages. Therefore, the need for power quality improving control strategies of grid-connected ...
