Parametric studies of translation invariance and distortion robustness in Convolutional Neural Networks
(North-West University (South Africa), 2021)Although Convolutional Neural Networks (CNNs) are widely used, their translation in-variance (ability to deal with translated inputs) is still subject to some controversy. We explore this question using translation-sensitivity ... -
Parametric study of thorium fuel cycles in a 100MWth pebble bed high temperature reactor
(North-West University, 2011)The current project was conducted in order to select an optimized open Thorium / Uranium fuel cycle for the Pebble Bed Modular Reactor (PBMR) concept in motivation for the 100MWth PBMR Power Plant. A sensitivity study on ... -
Patch-based pose invariant face feature classification
(North-West University, 2018)Real world face recognition systems are now successfully developed to recognise faces in frontal view. One of the most challenging tasks facing state-of-the-art face recognition algorithms is how to handle variations caused ... -
Performance and fouling prediction model for finned-tube heat exchangers
(North-West University (South Africa), 2020)Finned-tube heat exchangers (FTHXs) are found in abundance in heating, ventilation, and air-conditioning (HVAC) systems. This vital piece of equipment is used to either cool or heat the occupational environment. The thermal ... -
Performance assessment and mass energy balance for regenerative type air heaters
(North-West University (South Africa) , Potchefstroom Campus, 2016)The rapid development in South Africa over the last decade and the absence in new-build power plants have put enormous pressure on Eskom to reduce unplanned outages and increase the efficiency and reliability of the power ... -
Performance enhancing elements for an 18 m-Class glider
(North-West University (South Africa), 2011)The development history of aircraft can be seen as the quest for improved performance. This is also true for gliders where the aim is to design gliders that can fly faster and further than their predecessors. Improvements ... -
Performance evaluation of a gasifier cooling jacket by means of a homogeneous two-phase flow simulation model
(North-West University, 2000)SASOL II uses a number of coal-fired Gasifiers with water-cooled jackets to produce raw-gas for the purpose of manufacturing petroleum from coal. Excess heat generated by firing of the coal is removed with the aid of a ... -
Performance evaluation of GPRS/802.11b mobile-node initiated handover based on signal strength criteria
(North-West University, 2004)There has been a great concern by cellular providers about the impact Wireless Local Area Network (WLAN) systems that are based on 802.11b wireless standard pose to mobile business [24]. While cellular providers are still ... -
Performance evaluation of scheduling strategies for Field Force Automation traffic over GPRS
(North-West University, 2004)This study makes use of guidelines from other studies together with a lack of appropriate network simulation tools to develop an example data source model successfully that can be used for Field Force Automation ... -
Performance of different proton exchange membrane water electrolyser components
(North-West University, 2012)Water electrolysis is one of the first methods used to generate hydrogen and is thus not considered to be a new technology. With advances in proton exchange membrane technology and the global tendency to implement renewable ... -
Performance optimisation of vertical spindle coal pulverisers
(North-West University (South Africa) , Potchefstroom Campus, 2016)Coal pulverisers’ performance optimisation is an important process in power generation plants. Pulveriser operation is costly; reliability and availability is key to power generation and cost reduction is achieved by the ... -
Performance prediction for multi-effect distillation (MED) plants
(North-West University, 2007)Many countries worldwide experience water shortages on a daily basis and this water crisis is expected to increase even more in the near future due to limited fresh water resources. Alternative sources of fresh water ... -
Performance prediction for oil contaminated carbon dioxide flow boiling heat transfer in a smooth horizontal tube
(North-West University (South Africa) , Potchefstroom Campus, 2017)In recent years research into the identification and utilization of natural refrigerants with a low global warming potential, as a working fluid in heat pump cycles, has received much attention. One of these natural ... -
Performance predictions for oil contaminated supercritical carbon dioxide gas cooling
(North-West University (South Africa), 2019)The international movement towards using natural refrigerants has resulted in the reinvestigation of trans-critical heat pump cycles using carbon dioxide. Subsequently, a need to predict the heat transfer of oil-contaminated ... -
A performance-centered maintenance strategy for industrial DSM projects
(2015)South Africa’s electricity supply is under pressure because of inadequate capacity expansion in the early 2000s. One of the initiatives funded by Eskom to alleviate the pressure on the national electricity grid was an ... -
