(2006)Manufacturing techniques are based on the principles of Flexible Manufacturing and -
Reducing noise from wind turbines using active noise control.
(2014)Wind turbines while operating produce noise from the rotating mechanical parts and from the interaction of the blades with surrounding airflow. The noise produced by the blades consists of low frequency noise, airfoil ... -
The relationship between the bending amplitude and bending stress/strain at the mouth of a so-called square-faced clamp for different conductor sizes and different tensile loads : experimental approach.
(2013)In this research, realistic models were developed using experimental approach and statistical or deterministic analysis in the relationship between bending amplitudes and bending stress (strain) of the overhead line ... -

(2016)Abstract available in PDF file. -
Response characterisation of nanostructures subjected to uncertain loading and material conditions by convex modelling.
(2014)Nanostructures are fast becoming the material of choice consequentially opening a new research frontier. Classical continuum computational techniques have proven insu cient in modelling the mechanical behaviour of these ... -
Review of solar energy inclusion in Africa : a case study of Nigeria.
(2017)This work reviews solar energy inclusion in Africa using Nigeria as a case study. It reviewed studies made on viability, challenges and solutions associated with making solar energy a viable energy option in Nigeria. ... -
A semi-passive thermal management system for terrestrial and space applications.
(2013)In this study a semi-passive pulse thermal loop (PTL) was designed and experimentally validated. It provides improved heat transfer over passive systems such as the loop heat pipe in the moderate to high heat flux range ... -
Sensor based real-time mechatronic control of computer integrated manufacturing
(2008)Industrial competition is characterised by increasing globalisation of markets, coupled with -
Simulation and experimental evaluation of a hybrid flat-plate vacuum insulated photovoltaic and thermal power module.
(2014)Current Photovoltaic (PV) technologies are characterised by low conversion efficiencies due to the inability to fully absorb solar radiation within the spectral range. This results in the generation of residual heat and ... -
Smart materials for structural health monitoring.
(2003)A new philosophy in structural health monitoring was explored, with the view to the creation of a smart mining bolt: one which would bear the normal load of any bolt used in South African gold mining tunnels, but at the ... -
Smart structural health monitoring of mining support units.
(2003)In the South African mining industry, the design of tunnel support systems is generally based on empirical methodologies that consider rockmass characteristics as well as the type of loading (e.g. seismic) that the ... -
Software integration for human detection in mining UAV systems.
(2013)Mining is one of the main economic sectors in South Africa. Mining activity contains hazards such collapsing of structures, presence of dangerous gases, accidental explosions and fires. Even though most of these hazards ... -
Solar cells and global warming reduction.
(Research India Publications., 2018)This study proposes one way of addressing the issue of climate change and pollution using solar cells. The quality of life in developing and low-income countries is on the decline because of air pollution. Energy has a ... -
A state communication and software switching module and thin middleware layer for reconfiguration management in reconfigurable manufacturing systems.
Reconfigurable Manufacturing Systems are a new area of operations and manufacturing research. The global need for production systems which can react rapidly to dynamic markets has increased in the last decade and will ... -
Structural analysis of a composite monocoque chassis for use in a high performance electric vehicle.
