A comparison of surface NO2 mixing ratios and total column observations at a South African site
(SASAS, 2014)
The total column density nitrogen dioxide (NO2) retrievals collated by a ground-based
sun-tracking spectrometer (Pandora/GSFC) and the satellite-borne (Aura) Ozone
Monitoring Instrument (OMI) were compared to the volume ...
First year physics students' abilities and difficulties in solving kinematics problems in various contexts
(UNISA, 2014)
The topic of students’ application of conceptual knowledge in physics is constantly being researched. It is a common occurrence that students are able to solve numerical problems without understanding the concepts involved. ...
Aerosol properties over an urban site, Johannesburg measured from sunphotometer
(SASAS, 2014)
In this paper, we present results using ground based Sunphotometer (a passive
remote sensing instrument designed to study aerosol properties) as a part of NASA’s AERONET data. The analysis was based on the winter and ...
A Douglas-Shapiro-Shields factorization approach to the Leech equation
(MTNS, 2014)
In a recent series of papers concrete procedures
were derived to compute a stable rational matrix solution to the
Leech equation with rational matrix data. In one of these papers
the procedure involved a specific ...
Central stellar populations of brightest cluster galaxies
(South African Institute of Physics, 2014)
We analyse the stellar populations of a sample of brightest cluster galaxies (BCGs), for which high signal-to-noise ratio, long-slit spectra were obtained on the Gemini telescopes, by fitting their spectra using the software ...
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 ...
A comprehensive study of air quality in urban, low-income areas of South Africa
(SASAS, 2014)
Multi-year ambient air quality data from 4 networks (19 sites) in Gauteng have been analyzed, in
addition to data from intensive indoor and outdoor air quality monitoring in a small township in Mpumalanga
province. PM10 ...
The role of an ICT research professor in South Africa
(Sprouts Alliance, 2010)
Until recently it has been assumed that all lecturers at tertiary institutions should teach, conduct research and do community service. Due to heavy teaching loads, this assumption has become evident as a very idealistic ...
Comparing support vector machine and multinomial naive Bayes for named entity classification of South African languages
(PRASA, 2014)
In this study, two classical machine learning algorithms, multinomial naive Bayes and support vector machines, are compared when applied to named entity recognition for two South African languages, Afrikaans and English.
The ...
A census of South African industrial engineers, based on data extracted from Linkedin
(SAIIE, 2014)
The first South African Industrial Engineers graduated in 1963. Since then, the number of
graduates per annum has grown to more than 200 per annum. Many of these Industrial
Engineers use the social network, LinkedIn, to ...
