The 2-aryl-6,8-dibromoquinazolin-4(3H)-ones were prepared in a single-pot operation by condensing 6,8-dibromoanthranilamide and aryl aldehydes in the presence of molecular iodine in ethanol. Treatment of the 2-aryl-6,8-d ...
The optimized geometrical structures, the interaction energies, the basis set
superposition errors (BSSEs) and the infrared spectra of the monomers,
homodimers and the molecular complexes formed between BF3 and a number
of ...
The South African power utility, Eskom, and, in turn, the metropolitan and local
municipalities, have difficulty meeting the country's growing demand for electricity. In this
study, electric water heaters have been ...
nformation security (InfoSec) policies are widely used by institutions as a form of InfoSec control measure to protect their information assets. InfoSec policies are commonly documented in natural language, which is prone ...

The original two-variable integrodifferential equation for few-body systems is mod ified by introducing boundary conditions in the radial and angular domains. The
accuracy of the adiabatic approximation in solving this ...
This study investigated how the attitudes of taxi entrepreneurs affect their acceptance of transport management systems in the South African taxi industry. The study was instigated by a rise in the adoption of transport ...
Diesel fuel has been found to contain highly concentrated organo-sulphur compounds which have bad impact economically, environmentally, and health-wise. Adsorptive desulphurization (ADS) is one of the promising processes ...
This dissertation reviews the theory of fast matrix multiplication from a multilinear-algebraic point of view, as
well as recent fast matrix multiplication algorithms based on discrete Fourier transforms over nite ...
Ubiquitous computing is already weaving itself around us and it is connecting everything to the network of networks. This interconnection of objects to the internet is new computing paradigm called the Internet of Things ...
Copulas functions are a flexible tool for modelling the dependence structure between variables. The joint and marginal distributions of Copulas are not constrained by the assumptions of normality. This study examines the ...
The challenge facing South African foundries today are compliance with the environmental legislations while maintaining a high production rate. The focus of this study is to assist foundries to comply with National Environment ...
This research determines whether data quality mining can be used to describe, monitor and evaluate the scope and impact of semantic data quality problems in the learner enrolment data on the National Learners’ Records ...
Effective Governance of Enterprise Information Technology (GEIT) is very important for an enterprise that has a huge investment in IT infrastructure. Implementing effective GEIT helps an enterprise to meet stakeholder needs ...
The University of South Africa has built a small observatory for teaching and
research. The 35cm Schmidt-Cassegrain reflector and the SSP-5A photometer with
Johnson UBV filters were used to evaluate the local possibilities ...
This study empirically compares the Classical Test Theory (CTT) and the Partial Credit Model
(PCM) of Rasch focusing on the invariance of item parameters. The invariance concept which is
the consequence of the principle ...
The Vaalkop water treatment works (WTW) abstracts water from the Vaalkop Dam, which is situated in the Crocodile West/Marico Water Management Area of South Africa. The bulk of the inflow into the dam is through a canal fed ...
In an industrial application a GFAAS method for monitoring the Rh concentration in
process streams is being used. Matrix effects are known to exist with the application of
this technique; in fact, it was observed that ...
Computational creativity is an active area of research within the artificial intelligence domain that investigates what aspects of computing can be considered as an analogue to the human creative process. Computers can be ...
Nearly all present-day commercial intrusion detection systems are based on a hierarchical architecture. In such an architecture, the root node is responsible for detecting intrusions and for issuing responses. However, an ...
