Applying process mining to analyse business process performance in the Physical Asset Management environment
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: Physical Asset Management (PAM) has become a vital part of asset intensive
organisations in recent years. The rise of standards associated with Asset Management (AM) and the competitive nature of large ...
The analysis and optimization of an axial compressor
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: Axial compressors are widely used in a variety of contexts. When compared to centrifugal compressors, axial compressors offer higher pressure ratios and efficiencies. Due to the complex relationship between ...
Investigating the effect of aerodynamic damping on an axial flow fan blade
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: Axial flow fans used in air-cooled condensers experience a variation in blade loading due to distorted inlet flow patterns and obstacles in close proximity to the fan blades. The fan blades vibrate at ...
The suitability of a simultaneous analysis and design (SAND) formulation for ground structure based sizing optimisation of geometrically non-linear structures
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: Optimisation techniques have been applied to many practical engineering problems.
The authors were particularly interested in its application to the optimisation of structures. Haftka [1985] motivated ...
Small solar organic rankine cycle for electricity generation
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: The global the demand for energy has risen dramatically in recent years and the cost of
electricity has risen considerably. Local electricity sales prices followed the global trend,
increasing by an ...
Transient simulation of a lithium bromide-water vapour absorption refrigeration system
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: Vapour absorption is a thermally activated heat pump process that can be
used to produce refrigeration. The attraction of this technology is that it can harness low temperature sources of thermal energy ...
On alternative solution methods for solving approximate subproblems in SAO (Sequential Approximate Optimization)
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: In this study, we focus our attention on sequential approximate optimization
(SAO) techniques for large scale nonlinear constrained simulation based optimization
problems, and aim to add to the efficiency ...
A stand-alone parabolic dish solar cooker for African conditions
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: The reduction in the availability and the ever-increasing prices of fossil fuels, as well as the expensive and insufficient electricity supply, are some of the reasons explaining why the public awareness ...
Modelling and design of an oscillating wave energy converter
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: This thesis presents the experimental testing and development of a time-domain simulation model for a wave energy converter based on the principles of an oscillating water column. The device was developed ...
The Hybrid Pressurized Air Receiver (HPAR) for combined cycle solar thermal power plants
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Concentrating solar power technology is a modern power generation technology
in which central receiver systems play a significant role. For this technology a
field of heliostats is used to reflect solar ...
