This thesis presents the design of a test asset system capable of testing GNSS receivers for speed accuracy and the Uncertainty of Measurements (UOM) analysis for this system. The test asset system utilises a variety of engineering solutions and is capable of maintaining high accuracy benchmarks in speed measurements. The test asset system has an UOM equal 0.4 km/h for the entire range of speeds used for GNSS speed testing. The system was designed, assembled and tested to ensure the system maintains its integrity and capability to test GNSS receivers for speed measurement.

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 aim of this thesis is investigate and design a small antenna which can be embedded onto a Polyethylene substrate (used for making roof tiles). The antenna can be used to harvest ambient energy by connecting it to a rectifier. Due to the dimensional constraints of a roof tile as well as the materials used, there are limitations imposed on the antenna size, and thus the radiation efficiency and bandwidth often become a limiting factor in the overall performance of the system.

This thesis is the result of research into the different generations at work in an engineering consulting organisation in Victoria. The investigation was designed to research generational differences in values, attitudes and behaviours and their implications for management. This included a debate on whether the differences are generational or a consequence of age or stage-of-life.

This thesis investigates the choice behaviour of first year undergraduate students through proposing and testing a conceptual model. The psychological constructs of personal values, motivation, selection criteria, demographic and socioeconomic factors introduced as underlying drivers provide invaluable insight into the pathways of influence and relationships between student types and their preference towards a particular degree program at a particular university.
