A comparative analysis on blood pressure in HIV‐infected individuals versus uninfected controls residing in Sub‐Saharan Africa: a narrative review
(Wiley, 2019)
Purpose: Elevated blood pressure is a well‐documented risk factor for cardiovascular disease and mortality in Sub‐Saharan Africa (SSA). With SSA also affected by high Human Immunodeficiency Virus (HIV) infection rates, it ...
Statistical modelling of an ammonium nitrate fluidised bed granulator for inference measurement
(Elsevier, 2019)
Fluidised bed granulation is a widely used wet granulation technique. The operation of a fluidised bed granulator (FBG) as well as the quality of the product is strongly influenced by multiple process variables and ...
An energy-attributed graph approach for the purposes of FDI in a heated two-tank system
(Elsevier, 2019)
The focus of this paper is the development of attributed graph representations of industrial processes. In this case energy attributes are used since it serves a data reduction purpose and allows for the consideration of ...
Computational cost of an exergy-based fault detection scheme implemented in a commercial process simulator
(Elsevier, 2019)
Energy-based fault detection and isolation (FDI) schemes show promise in terms of applicability to petrochemical industries and the broader process industries. Model-based FDI schemes offer pronounced advantages over more ...
A proposed method for evaluating the frequency response of 22 kV outdoor current transformers for harmonic measurements in renewable energy plant applications
(IEEE, 2019)
With an increase in renewable energy plants connected to the national grid of South Africa the monitoring and assessment of power quality is becoming more important for utilities and independent power producers (IPPs). For ...
Kalman Filter based RFID tag velocity estimation in the presence of frequency hopping
(IEEE, 2019)
This paper compares different techniques for estimating the velocity of UHF RFID tags within practical applications. We use COTS RFID equipment complying with ISO18000-6C standards, including the use of frequency hopping, ...
Towards industry 4.0: a roadmap for the South African heavy industry sector
(Stellenbosch Univ, 2019)
The rapid growth and expansion of the Internet, as well as technical advances in the area of sensor technology, allow for the interconnection of physical objects for the purpose of achieving collective goals, which paves ...
Structuring uncertainty management for energy savings calculations
(Stellenbosch Univ, 2019)
South Africa has committed itself to reducing its greenhouse gas
emissions. A key strategy to minimise the greenhouse gas intensity
involves using incentivised energy efficiency initiatives. In South
Africa, one of these ...
Improving data management for environmental reporting in the gold mining industry
(Stellenbosch Univ, 2019)
Environmental reporting is a realistic alternative for mines to
prioritise operational changes in crucial environmental areas. Gold
mines report to multiple platforms – i.e., integrated reporting. All
these platforms ...
Industry 4.0 roll-out strategy for dynamic mine heat load management
(Stellenbosch Univ, 2019)
Deep-level mining is under severe financial pressure from several
unique challenges. One of these is maintaining acceptable
underground temperatures for humans to work in while achieving
demanding production targets. ...
