Evaluation of the wideband compressive radio receiver for spectrum sensing
We present an empirical evaluation of the carrier detection method used in the Wideband Compressive Radio Receiver (WCRR), which is of particular interest for spectrum sensing in Cognitive Radio (CR) and Dynamic Spectrum ...
Modified earliest decoding for random network codes
We present a practical, modified version of earliest decoding for random linear network coding networks. This decoding method has a lower complexity and decoding delay than traditional Gaussian elimination decoding schemes
A comparative analysis on blood pressure in HIV‐infected individuals versus uninfected controls residing in Sub‐Saharan Africa: a narrative review
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
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
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, ...
Sunspot identification and tracking with OpenCV
Space weather forecasting has gained interest over the past five decades since mankind started exploring space and began using highly developed technology. Dangers such as coronal mass ejections (CME) can negatively affect ...
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 ...
Co-administration of African potato and cisplatin for treating breast and prostate cancers using a Pheroid® delivery system
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. ...
