Changes in body composition and cardiometabolic risk among black South African adults
(Karger, 2017)Background and objectives: Obesity-related health risk may differ by ethnicity at the same body mass index (BMI). The objectives of this study were too determine the predictive value of the World Health Organization ... -
Characterization and modelling of a customs operation
(NWU, 2018)Effective risk management is a prerequisite to find an acceptable balance between the objectives of a customs operation and the streamlined flow of goods. This requires the use of well-designed customs risk management models ... -
The characterization of the severity of rotor delevitation events: a parametric study
(s.n, 2012)Active magnetic bearing (AMB) failure and the ensuing rotor behavior is a very important aspect of AMB safety. A model for this rotor behavior was developed and was used to characterize the severity of rotor delevitation ... -
Charge-sign dependent modulation of cosmic ray electrons and positrons up to extreme solar maximum conditions
(PoS, 2017)The charge-sign dependent modulation of cosmic rays is an important topic in solar modulation studies, providing insights into gradient, curvature, and current sheet drifts. Such studies, at higher levels of solar activity, ... -
Classifying bent radio galaxies from a mixture of point-like/extended images with machine learning
(IEEE, 2016)The hypothesis that bent radio sources are supposed to be found in rich, massive galaxy clusters and the avalibility of huge amount of data from radio surveys have fueled our motivation to use Machine Learning (ML) to ... -
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) ... -
Co-administration of African potato and cisplatin for treating breast and prostate cancers using a Pheroid® delivery system
(Elsevier, 2019)The cancer burden is increasing worldwide and is expected tobecome the most important barrier to increasing life expectancy 21stcentury. Low- and middle-income countries are expected to showthe biggest increase in incidence. ... -
Co-digestion of sweet sorghum bagasse with scientific and crude glycerols for electricity generation
(PSRC, 2014)With the global fossil fuel supplies dwindling and the alarming increase of carbon dioxide in the atmosphere, the need for alternative, clean energies, from carbon neutral sources is pressing. This impetus advanced research ... -
Coal product moisture control using stockpiles
(Springer, 2016)The moisture content of product coal is a major factor influencing the efficiency of downstream coal utilization processes. Product stockpiles are often used as a control measure to regulate the moisture content of the ... -
Colouring of dolomite, quartzite and dolerite mine dump rocks
(EARET, 2018)For environmental and aesthetic purposes it has become essential that mine dump rocks either blend into the environment or be used in the production of other products. Lately, there has been a constant need to produce ... -
Column leaching of fine coal tailings: impact on environment and thickener operation
(EARET, 2018)The coal mining sector is synonymous with generating large quantities of waste. A comprehensive fraction of the waste is classified as fines (-500 µm) and ultrafine (-100 µm) particles, which accounts eleven per cent ... -
A combination part of speech tagger using selected voting methods
(IEEE, 2019)The development of resources in any language is an expensive process, many languages, including the indigenous languages of South Africa, can be classified as being resource scarce, or lacking in tagging resources. This ... -
Combined electricity and water supply strategy for the department of water affairs
(IEEE, 2014)In the recent years various Demand Side Management (DSM) projects were successfully completed on Department of Water Affairs (DWA) pump schemes. Each pump scheme consists of a number of pump stations which transfer water ... -
A combined GPS/RFID system for improved cross-border management of freight consignments
(IEEE, 2013)Inefficiency of road freight transport is one of the primary factors that hamper the economy of sub-Saharan Africa. Long delays experienced at border posts are the single biggest contributor towards the slow average movement ... -
The combined modulation of Jovian and Galactic electrons in the heliosphere
(PoS, 2017)The propagation and modulation of electrons in the heliosphere play a significant role in improving our understanding and assessment of the competing processes of solar modulation. An in-house developed, full three-dimensional ... -
Combining different computational techniques in the development of financial prediction models
(SCITEPRESS, 2014)The prediction of financial time series to enable improved portfolio management is a complex topic that has been widely researched. Modelling challenges include the high level of noise present in the signals, the need to ... -
Combining empirical mode decomposition with neural networks for the prediction of exchange rates
(SCITEPRESS (Science and Technology Publications, Lda.), 2014)This paper proposes a neural network based model applied to empirical mode decomposition (EMD) filtered data for multi-step-ahead prediction of exchange rates. EMD is used to decompose the returns of exchange rates into ... -
Comparative adaptation of B. subtilis and P. aeruginosa in diesel supplemented medium and impact on biodegradation potential
(PSRC, 2014)The degree of diesel blending is likely to influence its toxicity as well as the susceptibility and speed of biodegradation. It is therefore imperative to identify strains that can degrade diesel blend in record time, such ... -
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 ... -
