The exceptional VHE gamma-ray outburst of PKS 1510-089 in May 2016
(PoS, 2017)PKS 1510-089 (z=0.361) is one of only a handful of flat spectrum radio quasars that have been detected at very high energy (VHE, E > 100GeV) gamma rays. It is a very active source across the entire electromagnetic spectrum. ... -
Expanding industrial thinking by formalizing the industrial engineering identity for the knowledge era
(IEOM, 2017)To date, the formal identity of the Industrial Engineer remains vague. D ue to the broad knowledge base and application areas made available to Industrial Engineers, pinning down the commonality has ... -
The expected very-high-energy flux from a population of globular clusters
(SAIt, 2015)Given their old ages, globular clusters are expected to harbour many evolved stellar objects. Their high core densities enhance stellar encounter rates, also facilitating the formation of stellar end products. In particular, ... -
Experimental results of an asynchronous machine with thermoelectric cooling modules
(2012)It is estimated that globally around 40% of the electricity supplied to the industrial sector is consumed by electric motorised systems and for South Africa around 60% of the electricity supplied is consumed by asynchronous ... -
Experimental study on liquid hydrocarbon formation during pressurized underground coal gasification conditions
(2018)UCG is a gasification process used to produce synthesis gas from coal in situ (underground in the coal seam) by injecting air or oxygen, with or without steam, into coal seams and extracting the product gas via surface ... -
Experimentelle und theoretische Untersuchungen zum Rotorabsturz in Wälzlager
(2011)Um eine Auslegung von Fanglagern durchzuführen ist es notwendig, die Belastungen dieser in den zu erwartenden Abwurfszenarien zu kennen. Da so ein chaotischer Vorgang schwer analytisch berechnet werden kann, ist es ... -
Exploiting high-energy polarization in blazars
(Sissa Medialab, 2018)The spectral energy distributions (SEDs) and variability of astrophysical sources can be modeled in many different ways, in particular, the production of X-rays and γ-rays in the SEDs of blazars. High-energy polarimetry ... -
Exploration of biomarkers for subclinical atherosclerosis in an African population using a proteomics chip targeted at inflammation and cardiovascular disease
(Oxford Univ Press, 2019)Introduction: The evolving use of multiplex proteomic platforms provides an excellent tool for investigating associations between multiple proteins and subclinical atherosclerotic disease. In this study, we evaluated the ... -
Exploring a gene-x-environment model of treatment resistant depression: behavioural studies and response to fluoxetine treatment
(Elsevier, 2019)Background: Major depression with psychotic features presents with severe depressed mood and psychosis in the form of nihilistic-type delusions and hallucinations, and is known to be resistant to antidepressant monotherapy ... -
The extended jet in AP Librae as the source of the VHE γ-ray emission
(AIP, 2017)Most modeling attempts of blazars use a small emission zone located close to the central black hole in order to explain the broad-band spectral energy distribution. Here we present a case where additionally to the small ... -
External contextual factors in information security behaviour
(SITEPRESS, 2020)Human behaviour is often considered to be irrational, difficult to understand, and challenging to manage. This phenomenon has a direct impact on the way in which humans behave when confronted with information security ... -
Extracting the February 1956 ground level enhancement event from legacy cosmic ray recordings
(Springer, 2018)Early continuous recordings of cosmic rays, as measured with Carnegie Type C Ionization Chambers, were made on rolls of photographic paper. This paper describes the extraction of the ionization data of the February 1956 ... -
Extracting the ground level enhancement event of February 1956 from Legacy cosmic ray recordings
(IEEE, 2018)Early continuous recordings of cosmic rays, as measured with Carnegie Type C Ionization Chambers, were made on rolls of photographic paper. This paper describes the extraction of the ionization data of a ground level ... -
The extraction of the temperature gradient from measured temperature profiles with uncertainty propagation, as applied to the high temperature test unit
(SAAM, 2010)This paper highlights the usefulness of applying analytical methods for uncertainty analysis to a least-squares polynomial fit. It also presents an equation to calculate the confidence interval in the slope of a regression ... -
Feasibility of cultivating Hartbeespoort Dam microalgae
(ETA-Florence Renewable Energies, 2011)Three cultivation experiments were conducted to grow microalgae in three consecutively scaled-up laboratory systems, which consisted of one, five and 135-litre bioreactors. The highest productivity achieved under optimum ... -
The feasibility of raising information security awareness in an academic environment using SNA
(Springer, 2018)The human aspect is one of the key success factors in information security (InfoSec). Its impact on InfoSec is so significant that multiple studies have shown that a balanced approach combining technology and security ... -
Fermentation of lignocellulosic biomass using ultrasonic pretreatment
(ETA-Florence Renewable Energies, 2014)The potential fermentation of the sugars derived from water hyacinth, sweet sorghum bagasse and amaranth using indirect ultrasonic pretreatment, was investigated. The optimum sugar and ethanol yield for the ultrasonic bath ... -
Field performance of ambient modal estimation in small signal stability
(IEEE, 2015)Small signal stability is one focus of Wide Area Measurement Systems (WAMS). WAMS systems are becoming more widespread, driven by availability of synchrophasor data from Phasor Measurement Units (PMUs). In this paper, two ... -
Financial analysis of waste-to-energy grate incineration power plant for a small city
(IEEE, 2015)Grate incineration is a widely used waste-to-energy (WtE) technology, which has the potential of contributing significantly to clean energy production and sustainable waste management systems. Various research studies have ...
