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.

This thesis presents a pro–active research work motivated by the prospect of the imminent implementation of the regulatory requirement for pedestrian protection, Global Technical Regulation–9 (GTR–9) (United Nations Economic Commission for Europe 1998) in the near future. To meet the performance criteria for pedestrian protection head impact, it is vital to incorporate the required design parameters into the hood design process at an early stage. These main design parameters are architectural and changing them late in the vehicle design process is very expensive and difficult to implement.

This research project explores the effectiveness of an auditory display prototype for the sonification of internet \(c{o_2}\) emissions to a small user group within their office context. To date, methods do not exist for the reporting of this information to users of personal computing while they perform simple internet enquiries. Underpinning the theoretical development of this project is a focus on auditory displays guided by the concept and forms of auditory displays, together with the auditory perception elements to be considered in their design.

This research focuses on Fibre Cement Felts (FCF), which is a non-woven textile substrate acting as a conveyor belt for the manufacturing of Fibre Cement Sheets (FCS). Fibre Cement Felts are a valued component required in the manufacturing process of Fibre Cement Sheets, used in construction for today’s building industry. Identifying the key factors that most influence FCF will assist in understanding of the relationship between fibre diameters, carded web, and mechanical bonding.

Optimum Flight Trajectories for Terrain Collision AvoidanceThe objective of this research is to introduce a new methodology that computes optimal escape trajectories within a three dimensional digital terrain. It has been established that conducting a pull up manoeuvre may not always be the best option for a pilot to salvage the aircraft in the case of an imminent collision. To prove this further, several simulations were conducted which shows that performing a lateral turn can produce safer trajectories in comparison to a vertical pull up.

The main objective of this research is to optimize the design of the Tunnel kiln for efficient fuel usage. To achieve that, the temperature distribution from the simulation needs be matched with the desired Tunnel kiln curve found in industry. This objective can be achieved by CFD simulation where temperature, velocity and emission distributions inside the Tunnel kiln can be obtained. Generated temperature distribution can be matched with the industrial curve and by interpreting the curve, efficient design can be suggested.

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.

In this research the effect of ground proximity on the lift, drag and moment coefficients of inverted, two-dimensional aerofoils was investigated. The purpose of the study was to examine the effect ground proximity on aerofoils post stall, in an effort to evaluate the use of active aerodynamics to increase the performance of a race car. The aerofoils were tested at angles of attack ranging from 0° – 135°. The tests were performed at a Reynolds number of 2.16 x 105 based on chord length. Forces were calculated via the use of pressure taps along the centreline of the aerofoils.

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.

Municipal wastewater treatment plants generally utilise biological activated sludge processes to remove organic compounds and nitrogen. The biological nitrogen removal (BNR) occurs in two steps, nitrification (ammonium removal) and denitrification (nitrates removal). This study focused on a medium-sized wastewater treatment plant (WTP) which experienced poor nitrification for years, mainly when the weather temperature drops.
