1D and 3D numerical simulation of the reactor cavity cooling system of a very high temperture reactor
(IHTC, 2014)To avoid accidents due to human error or the failure of components, the reactor cavity cooling system (RCCS) of a high temperature reactor must be able to operate naturally or passively safe. The RCCS can be a buoyancy ... -
2D methods for pose invariant face recognition
(IEEE, 2017)The ability to recognise face images under random pose is a task that is done effortlessly by human beings. However, for a computer system, recognising face images under varying poses still remains an open research area. ... -
Acceleration of galactic electrons at the solar wind termination shock and Voyager 1 observations
(PoS, 2017)Diffusive shock acceleration (DSA) , as an acceleration process for G alactic electrons at the solar wind termination shock (TS) , is investigated with a comprehensive numerical model which ... -
Accounting for porous structure in effective thermal conductivity calculations in a pebble bed reactor
(Atomic Energy Society of Japan, 2009)A proper understanding of the mechanisms of heat transfer, flow and pressure drop through a packed bed of spheres is of utmost importance in the design of a high temperature pebble bed reactor. A thorough knowledge of the ... -
Action evolution for intelligent agents
(IEEE, 2005)This paper introduces an alternative method of reinforcement learning for intelligent agents. The aim with this method is to closer emulate the natural thought processes of problem solving. This paper only provides a ... -
Active surface area approximation in a lead-acid cell for optimal performance in renewable energy systems
(IFAC, 2014)In a renewable energy system, lead-acid batteries are required to last as long as possible whilst providing deep discharges and are usually charged in an intermittent manner. This type of operation is severely detrimental ... -
Adapting mobile medical information search to low-resourced areas
(IST-Africa, 2013)Providing good medical care in low-resourced areas is a challenge faced by many low and middle income countries. Continuously improving mobile communication infrastructure in these areas is however providing the opportunity ... -
Addressing the total human being: work-integrated learning for ICT student
(IADIS Press, 2013)Information and communication technology (ICT) is essential to the operation of business, and create many employment opportunities. High volumes of students graduate in ICT however students struggle to find job placement. ... -
The adoption of m-commerce applications: rural dwellers’s perspectives
(IADIS, 2019)In recent years, mobile applications (mobile apps) have gained widespread acceptance. Mobile apps services have effectively encircled most of the human activities, with the purpose of improving the living standard of the ... -
Adsorption of metal ions from fine coal tailings dump waste water using bio-char
(EARET, 2018)Coal mining operations produce large amounts of tailings which contains heavy metals. Heavy metals such as cadmium (Cd) can cause environmental problems. The adsorption capacities of biochars produced from spent coffee ... -
Adsorption potential of bentonite and attapulgite clays applied for the desalination of sea water
(PSRC, 2014)A possible new process for the partial desalination of seawater is to use bentonite clay or attapulgite as an adsorbent. The ion exchange property of these clays, which is a result of the characteristic t-o-t layer ... -
The adversarial threat posed by the NSA to the integrity of the internet
(IEEE, 2015)In 2013, Edward Snowden, a NSA Contractor leaked thousands of highly classified documents about the activities of the USA's National Security Agency (NSA) and its foreign intelligence partners known as the "Five Eyes" ... -
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 ... -
The African data intensive research cloud
(IEEE, 2016)The African Data Intensive Research Cloud project aims to establish resources to support data intensive radio astronomy research among collaborating partners in South Africa and African Square Kilometre Array telescope ... -
The aid of optical studies in understanding millisecond pulsar binaries
(Sissa Medialab, 2016)A large number of new “black widow” and “redback” energetic millisecond pulsars with irradiated stellar companions have been discovered through radio and optical searches of unidentified Fermi sources. Synchrotron emission, ... -
Alcohol and the oculomotor neural circuit: system identification, a delay-based approach
(IEEE, 2015)A fair amount of research has been done on the modeling of the oculomotor system. Models of the oculomotor neural circuitry that include the effect of alcohol are less plentiful in literature. We investigated the ... -
Aligning student and educator capstone project preferences algorithmically
(IEEE, 2018)This paper reviews recent attempts by researchers at the University of Johannesburg (UJ) to increase the level of student engagement in a final year capstone project by allowing for a greater level of autonomy in project ... -
Analysis of export and employment opportunities for the South African manufacturing industry
(2015)The South African government recognises the importance of promoting manufactured exports as a means of ensuring sustainable economic growth and job creation. However, export promotion organisations have limited resources ...
