Instrument transformers influence on harmonic measurements for grid code compliance
(IEEE, 2019)
With an increased penetration of renewable energy sources in South Africa, especially photovoltaic (PV) and wind farm generating plants, power quality is becoming more important for utilities. With that also the accuracy ...
The use of optimisation modelling for energy recovery investment decision making
(IEEE, 2019)
Investment decision making is a common occurrence
for any engineering company. These investments include any
possibility from relative inexpensive to extremely costly
equipment. When power generation turbine procurements ...
A methodology to determine best-suited waiting-time periods for turbine start-up under fluctuating resources
(IEEE, 2019)
— It is not uncommon for engineering process
plants to comprise energy recovery. When power generation
takes place under such circumstances, the nature of
interlinked processes may result in fluctuating resource
availability. ...
Cloud-based business intelligence for a cellular IoT network
(IEEE, 2019)
This paper presents a cloud-based business intelligence (BI) implementation for a cellular Internet of Things (IoT) network. A Design Science Research (DSR) paradigm, combined with elaborated Action Design Research (eADR) ...
Evaluation of a facial recognition engines for a surveillance system
(IEEE, 2019)
This paper presents the evaluation of a facial recognition system when considered in an operational context for the South African environment. Often, performance measures, such as recognition rate, are considered outside ...
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 ...
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 ...
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 ...
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, ...
