Novel electroluminescence technique to analyze mixed reverse breakdown phenomena in silicon diodes (Elsevier, 2010-04)In this paper a novel technique to analyze the low-voltage breakdown regime of silicon diodes is presented. It is shown that the field emission tunnel current component of the reverse current does not cause energy transitions ...
-
(University of Pretoria, 2005-09-22)The objective of this study was to provide an adequate model of the k-factor for scientific radio planning in South Africa for terrestrial propagation. An extensive literature survey played an essential role in the research ...
-
(HEFAT, 2016)Jet control is of great interest to a wide range of industrial and environmental applications. This work presents an investigation on the closed-loop control of a turbulent round jet for enhancing the jet mixing. The ...

A novel face recognition system in unconstrained environments using a convolutional neural network (University of Pretoria, 2018)The performance of most face recognition systems (FRS) in unconstrained environments is widely noted to be sub-optimal. One reason for this poor performance may be due to the lack of highly effective image pre-processing ...
-
(University of Pretoria, 2018)Operational discharges of oil from vessels, whether accidental or deliberate, are a growing concern as the levels of maritime traffic increase. Oil tankers and other kinds of ships are among the suspected offenders of ...
-
(CONSAS Conference, 2017-10)Human settlement expansion is one of the most prominent types of land cover change in South Africa. These changes typically occur in areas that are covered by natural vegetation. Methods that can rapidly indicate areas ...
-
(Springer, 2016-11)For several decades graphs act as a powerful and flexible representation formalism in pattern recognition and related fields. For instance, graphs have been employed for specific tasks in image and video analysis, ...
-
(Elsevier, 2016-11)This study presents an innovative new alternative for utilizing phase change materials as energy storage media in solar power towers. The solar power tower prilling or granulation concept combines the existing molten ...

(American Society of Mechanical Engineers, 2018-05)Blade tip timing (BTT) is a noncontact method for measuring turbomachinery blade vibration. Proximity sensors are mounted circumferentially around the turbomachine casing and used to measure the tip displacements of blades ...
-
(Czech Academy of Agricultural Sciences, 2017)Transportation of tomatoes on farm and market roads causes interfacial stresses of tomatoes due to truck dynamics as affected by road and transportation conditions. These stresses may affect the shelf-life of tomatoes if ...
-
(Elsevier, 2016-05)Rapid thermal conductivity measurement of porous solids and composites remains a challenge. A modified steady state technique has been proposed which uses two heat flux sensors instead of one. The parameter estimation ...
