3D modelling segmentation, quantification and visualisation of cardiovascular magnetic resonance images.
(2014)Progress in technology in the field of magnetic resonance imaging (MRI) has provided medical experts with a tool to visualise the heart during the cardiac cycle. The heart contains four chambers namely the left and right ... -
A semi-empirical formulation for determination of rain attenuation on terrestrial radio links.
(2010)Advances in today’s fast growing communication systems have resulted in congestion in the lower frequency bands and the need for higher capacity broadband services. This has made it inevitable for service providers to ... -
A study of rain attenuation on terrestrial paths at millimetric wavelengths in South Africa.
(2006)Rain affects the design of any communication system that relies on the propagation of electromagnetic waves. Above a certain threshold of frequency, the attenuation due to rain becomes one of the most important limits to ... -
Accelerated environmental degradation of GRP composite materials.
(2004)The use of fibre reinforced polymer composites and development of structural composites has expanded rapidly in the Southern African region over the past ten years. The long-term effect of placing these materials outdoors ... -
Activity of complex multifunctional organic compounds in common solvents.
(2009)The models used in the prediction of activity coefficients are important tools for designing major unit operations (distillation columns, liquid-liquid extractors etc). In the petrochemical and chemical industry, well ... -
Adaptive dynamic matrix control for a multivariable training plant.
(2001)Dynamic Matrix Control (DMC) has proven to be a powerful tool for optimal regulation of chemical processes under constrained conditions. The internal model of this predictive controller is based on step response measurements ... -
Adaptive model predictive control of renewable energy-based micro-grid.
(2021)Energy sector is facing a shift from a fossil-fuel energy system to a modern energy system focused on renewable energy and electric transport systems. New control algorithms are required to deal with the intermittent, ... -
Adaptive multiple symbol decision feedback for non-coherent detection.
(2006)Non-coherent detection is a simple form of signal detection and demodulation for digital communications. The main drawback of this detection method is the performance penalty incurred, since the channel state information ... -
An adaptive protocol for use over meteor scatter channels.
(1987)Modem technology has revived interest in the once popular area of meteor scatter communications. Meteor scatter systems offer reliable communications in the 500 to 2000 km range all day, every day. Recent advances in ... -
Adaptive sedimentation and patch optimization for multi-viewed stereo reconstruction.
(2015)This dissertation presents two main contributions towards the Patch-based Multi-View Stereo (PMVS) algorithm. Firstly, we present an adaptive segmentation method for preprocessing input data to the PMVS algorithm. This ... -
Adaptive techniques with cross-layer design for multimedia transmission.
(2013)Wireless communication is a rapidly growing field with many of its aspects undergoing constant enhancement. The use of cross-layer design (CLD) in current technologies has improved system performance in terms of ... -
Adsorption of heavy metals on marine algae.
(2005)Biosorption is a property of certain type of inactive, microbial biomass to bind and concentrate heavy metals from even very dilute aqueous solutions. Biomass exhibits this property, acting just as a chemical substance, ... -
Adsorption studies for the separation of light hydrocarbons.
(2014)Traditionally, the separation of ethylene from ethane is undertaken using a fractionation sequence. The distillation is performed at low temperatures and elevated pressures in conventional trayed fractionators. For economic ... -
The advancement of the waste resource optimization and scenario evaluation model: the inclusion of socio-economic and instituitonal indicator.
(2018)This study explored Novice Teacher Educators (NTEs) experiences of Relational Learning in a private Higher Education Institution (HEI) in South Africa. The main purpose of this study was to gain a deeper understanding ... -
Aerodynamic modelling and further optimisation of solar powered vehicle.
(2016)Computational fluid dynamics was used to optimise the aerodynamics of a solar powered vehicle via the addition of airflow alteration devices that interact with the boundary layer airflow. These features were designed, ... -
Alternative approach to Power Line Communication (PLC) channel modelling and multipath characterization.
