The prediction of the expected long-term performance of concrete exposed to sewage and similar materials can be difficult as it is affected by a large number of parameters. In addition, the deterioration process in concrete is generally slow. The focus of the study was to ascertain the life expectancy of concrete septic tanks located in rural Victoria. In developing the accelerated test method, ASTM C 192, ASTM C 452, ASTM C 1293 and ASTM C 109 standard procedures were adopted wherever possible.

Magnetic bearing systems have received much attention in the research community for the past decades. Its inherent nonlinearity and open-loop instability present challenges for controller design. This thesis investigates and designs model predictive control (MPC) systems for an experimental Active Magnetic Bearing (AMB) laboratory system. A host-target development environment of real-time control system with hardware in the loop (HIL) is used for implementation of the predictive control systems. In this thesis, both continuous and discrete time model predictive controllers are studied.

In this thesis, the rolling contact wear of 52100 bearing steel and Over-aged Magnesia-Partially-Stabilised Zirconia (OA-Mg-PSZ) ceramic are examined using a newly developed rolling contact wear test rig. The new wear test rig simulates the system geometry of an un-lubricated hybrid (ceramic and steel) ball bearing. The new wear test rig is versatile in that it allows low cost samples to be utilised resulting in a larger number of samples that can be tested.

The purpose of this project is to enable the prediction of flow behaviour of concentrated slurries in the pipe loop under various laminar flow conditions using the fluid analogue to slurry and to find the suitable rheological model from the literature for the fluid analogue and tailings from the Sunrise dam. The major objective of the project is to develop a fluid analogue which will have similar rheological behaviour to that of the tailings from Sunrise dam so that it can be used as a test material to predict the flow behaviour of tailings in a pipe.

Model Predictive Control (MPC) refers to a class of algorithms that optimize the future behavior of the plant subject to operational constraints. The merits of the class algorithms include its ability to handle imposed hard constraints on the system and perform on-line optimization. This thesis investigates design and implementation of continuous time model predictive control using Laguerre polynomials and extends the design approaches proposed in to include intermittent predictive control, as well as to include the case of the nonlinear predictive control.

The main focus of this thesis is on the application of a model predictive control (MPC) method to devise an ABS for a BBW vehicle. Unlike the traditional ABS control algorithms which are based on a trial and error method, the MPC based ABS algorithm aims to utilizes the behaviour of the model to optimize the wheel slip dynamics subject to system constraints. Performance of the proposed wheel slip controller is validated through Software-in-the-Loop (SiL) and Hardware-inthe-Loop (HiL) simulation.

The project's main objectives were to analyse the data obtained during geological exploration and use it to model and predict biological patterns in order to answer the main research questions: 1) Is there a statistical relationship between the environmental parameters and the benthic community composition and morphospecies observed? 2) Can predictive models be developed from this relationship? In achieving these main objectives, the project also developed recommendations for methods that could be applied during geological exploration voyages to maximise the potential use of data collected.

This research reviews the current knowledge and contributes to research efforts of rail track degradation models. The main focus is to understand the behaviour of each model, taking into consideration the variables and factors. This research presents models to predict the tram track degradation of Melbourne network based on its influencing factors. It improves decision-making on degradation models in order to optimise and prioritise maintenance practices and minimise track defects.

The broad aim of this research project is to optimize planned and emergency maintenance tasks and timings for tram tracks. Consistent with that broad aim, the following specific objectives are identified: Understand the factors affecting the degradation of tram tracks; develop a degradation prediction model for tracks as a function of the influencing factors; evaluate the time and type of maintenance required for deteriorated rail tracks.

This thesis provides solid evidence to support the notion that idiosyncratic volatility plays a significant role in Australian equity markets. Therefore, it should not be ignored but instead should be considered when evaluating the performance of Australian stock portfolios and pension funds. It can also be used to predict Australian economic conditions.

The recent advances in the study of the unique capabilities of monolayer crystals had predicted piezoelectricity in two-dimensional (2D) group IV chalcogenides which are not present in their bulk forms. In this study, the predicted piezoelectric properties of was experimentally explored through Piezoelectric Force Microscopy (PFM). Tin Sulfide (SnS), Tin Selenide (SnSe), Germanium Sulfide (GeS), were exfoliated from their bulk forms by the top down methods of liquid sonication, while and Tin Disulfide (SnS2) mechanically exfoliated by tape.

This study uncovers a wide range of complex transport dynamics in transiently forced aquifers that has profound implications for the understanding and quantification of solute transport in these important groundwater systems. And the results in this thesis predict that complex transport structures and dynamics arise in natural transiently forced aquifers around the world. When such dynamics do arise, it will lead to mixing and reactive transport patterns that are very different from those predicted by conventional Darcy flow models.
