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.
(2018)The adoption of electric vehicle technology is becoming more prevalent, as society strives to reduce the negative impact of greenhouse gas emissions and focuses on a sustainable future. This thesis details the design and ... -
Structural characterisation and response modelling of paraffin-based hybrid rocket motor fuel grains.
(2020)Abstract available in PDF. -
A study and implementation analysis of an anti-sagging device for power transmission lines using shape memory alloys
(2010-08-31)Shape memory alloys (SMA’s) are a family of metals that exhibit properties of pseudo-elasticity -
Study of a solar-assisted air conditioning system for South Africa.
(2012)In South Africa, a significant amount of electrical energy is used for air conditioning in commercial buildings, on account of the high humidity experienced. Due to its geographical location, the levels of solar irradiation ... -
Thermal shock and CFD stress simulations for a turbine blade.
(2002)A 2-D CFD / FEM model to simulate thermal stresses in a turbine blade has been set up using the software FLUENT and FIDAP. The model was validated against the data of Bohn et. al. (1995) and was used to simulate 5 ... -
Thermal shock and thermal stress prediction on a highly loaded turbine nozzle guide vane based on an aerodynamic and thermal analysis.
(2005)A 2-D plain strain CFD/FEM model to simulate thermal shocks and stresses in a turbine blade has been set up using the commercially available software FLUENT and NASTRAN. The model was validated against the experimental ... -
Trip steels as smart sensor alloys.
(2013)Upon deformation, TRIP steels undergo progressive irreversible transformation from paramagnetic austenite to more thermodynamically stable, ferromagnetic αʹ-martensite. The change in magnetic permeability is readily ... -
The use of discrete event simulation techniques to optimize a proposed factory layout.
(1989)This project has proved conclusively that discrete event simulation techniques can be used to simulate, on computer, a complex stochastic materials handling system. The packing, automatic palletising and warehousing ... -
Variable sensor system for guidance and navigation of AGVs.
(2008)Automated Guided Vehicles (AGVs) depend on sensor systems to guide and navigate in manufacturing environments. The sensor system must ensure the correct path is followed and monitor the vehicle’s progress as it proceeds ... -
Virtual prototyping of an articulated dump truck.
(2003)In the modem automotive industry product times to market are being increasingly compressed. In the earthmoving and construction machine industry this is also true with the manufacturer having to respond to new customer ... -
