(University of Pretoria, 2014)Iterative learning control (ILC) is a repetitive control scheme that uses a learning capability to improve the tracking accuracy of a desired test system output over repeated test trials. ILC is sometimes used in response ...
-
(University of Pretoria, 2014)In the pursuit of more accurate diagnostics of turbo machinery sophisticated rotor and bearing models are to be developed in order to better understand the dynamics of the rotor-bearing system. This study is concerned with ...
-
(University of Pretoria, 2014)This study aims to generate from a three-dimensional data set of carbon dioxide ux in the Southern Ocean, a sample set for use with Kriging in order to generate estimated carbon dioxide ux values across the complete ...
-
(University of Pretoria, 2014)Diagnostics and prognostics in rotating machinery is a subject of much on-going research. There are three approaches to diagnostics and prognostics. These include experience-based approaches, data-driven techniques and ...
-
(University of Pretoria, 1976)Die onbevredigende konsep van die interne wrywingskoeffisient wat as basis dien vir numeries-bruikbare fraktuurkriteria vir brosmateriale, onder andere die van Coulomb-Mohr, impliseer dat daar meriete in die kriteria ...
-
(University of Pretoria, 2014)In this study, topology optimisation for heat-conducting paths in a three-dimensional domain was investigated. The governing equations for the temperature distribution were solved using the finite volume method, the ...
-
(University of Pretoria, 2014)The work presented in this dissertation on piezoelectric inchworm motors (IWM) is part of a process to gain an understanding of the design, analysis and testing of this smart actuator technology. This work will form the ...
-
(University of Pretoria, 2013)Vehicle dynamic simulations form a significant part of the design and development process of vehicles. These simulations are used to study and improve the vehicle’s durability, ride comfort and handling capabilities. All ...
-
(University of Pretoria, 2014)It is widely known that Central Corneal Thickness (CCT) and Radius of Curvature (RoC) in uence the estimated IntraOcular Pressure (IOP) obtained from Goldmann Applanation Tonometry (GAT). However, not much is known about ...
-
(University of Pretoria, 2014)This study consists of an experimental investigation into the fluid flow and heat transfer aspects of microchannels. Rectangular copper microchannels of hydraulic diameters 1.05 mm, 0.85 mm and 0.57 mm were considered. ...
-
(University of Pretoria, 2013)An autonomous vehicle is a vehicle that is capable of navigating and driving with no human intervention whatsoever through the utilization of various sensors and positioning systems. The possible applications of autonomous ...
-
(University of Pretoria, 2013)Abstract The reinforcement of concrete with steel fibres changes the failure of the composite material from catastrophic brittle failure to pseudo-ductile behaviour as a result of crack-bridging by the fibres, and the ...
-
(Elsevier, 2014-08)The aim is to investigate the improvements in vehicle safety that can be achieved by limiting the vehicle speed based on GPS path information. The control strategy is aimed at reducing vehicle speed before a potentially ...
-
(University of Pretoria, 1997)Practicing engineers need an integrated building, HVAC and control simulation tool for optimum HVAC design and retrofit. Various tools are available to the researchers, but these are not appropriate for the consulting ...
-
(University of Pretoria, 1965)In order to establish the rules and criteria· to be satisfied in order to develop a scale model, which may be employed to predict the dynamic behaviour of a fullscale rope-guide mineshaft installation, the theory of the ...
-
(University of Pretoria, 2013)Varying diameter ratios associated with smooth concentric tube-in-tube heat exchangers are known to have an effect on its convective heat transfer capabilities. Much literature exists for predicting the inner tube’s heat ...
-
(University of Pretoria, 2012)The continual advance in manufacturing processes has resulted in significantly more compact, high performance, devices. Consequently, heat extraction has become the limiting factor, and of primary concern. Therefore, a ...
-
Damage detection methodology for composite UAV wings using modal analysis and probabilistic concepts (University of Pretoria, 2011)Monitoring of structural integrity is critical in many fields today, and particularly so in the civil, mechanical and aerospace engineering industries. In the aerospace industry, appreciably sized and almost exclusively ...
-
(University of Pretoria, 2013)The purpose of this study is to mitigate the compromise between ride comfort and handling of a small single seat off-road vehicle known as a Baja. This has been achieved by semi-active control of the suspension system ...
-
(University of Pretoria, 2012)Most drill wear monitoring research found in the literature is based on conventional vibration technologies. However, these conventional approaches still have not attracted real interest from manufacturers for multiples ...
