Determinants of Services Exports Performance: The Role of Foreign Direct Investment and Existing Industrial Capabilities
No full textThis thesis examines how countries develop expertise in service exports through three interconnected studies. First, it analyses how inward foreign investment in the service sector influences different types of service exports globally. Second, it examines how inward foreign investment affects Australian firms' service exports, finding that foreign presence creates spillovers that enhance export capabilities. Finally, it reveals that knowledge from manufacturing supports specialisation in service exports, although developing countries often struggle to benefit. By focusing on the fast-growing but often overlooked service sector, this research offers practical insights for policymakers and business leaders aiming to strengthen the service sector.</p
Design and Development of AGV-based IoT Solution for Greenhouse Environmental Monitoring
No full textPrecision farming today has seen wide adoption and has been developed to perform a wide range of applications including monitoring, irrigation, weeding and harvesting of crops. However, it is difficult to implement these systems on a large scale as the infrastructure and cost needed would scale along with it. This project will investigate this problem and attempt to formulate a solution by proposing and develop a mobile robot to be used on existing farms without the need for additional infrastructure and can serve as a platform for different functions from gathering sensor data to interacting with the plants directly.</p
Design and Development of a Metamaterial-Based Protective Headband for Mitigating Sports Injuries
No full textThis thesis focuses on creating a new lightweight headband to help reduce head injuries in sports. The headband uses specially designed foldable structures and advanced materials to absorb impact effectively while remaining comfortable and easy to wear. Tests and computer simulations show that this design can significantly lower the force on the head during impacts, improving safety for athletes. This work supports the development of better protective gear that athletes are more likely to use, contributing to safer sports environments.</p
Understanding Gas Flows in-and-around Galaxies
No full textThe circumgalactic medium is a multiphase halo surrounding individual galaxies that significantly influence galaxy formation and evolution. The direct observation of the CGM is challenging due to the diffuse nature of CGM gas, resulting in limited observational evidence for accretion and outflows. This thesis demonstrates the complex and multiphase nature of the CGM, and reveals the kinematic behaviour of the multiphase CGM gas flows and their host galaxies. It emphasizes the importance of conducting statistical analysis on various CGM ions to unveil the intricate connection between galaxies and their circumgalactic halo
Performance assessment of 3d printed wall modules
No full text3D concrete printing is increasingly becoming popular as it provides a powerful platform for the fabrication of structural components in freeform architectural shapes. While manufacturing technology and material property improvement are advancing rapidly, the development of methods to predict the structural capacity of printed elements is lagging. This research presents an experimental and numerical investigation of printed concrete wall modules. the numerical model is developed by introducing material characteristics taken from printed prototypes to predict module axial capacity. Also, to study the structural performance of an entire wall, four modules are connected together and investigated experimentally and numerically
Signals Affecting Crowdfunding Success for Australian Social Enterprises
No full textThis study adopted the signalling theory and suggests that Australian social enterprises can achieve crowdfunding success through different combinations of costly signals - expensive (in resources) to obtain signals and costless signals - less expensive (in resources) to obtain signals. Using qualitative comparative analysis, this study examined crowdfunding campaigns run by Australian social enterprises and concluded that (1) different combinations of costly and costless signals can lead to crowdfunding success, (2) costless signals of campaign preparedness are fundamental and (3) third-party endorsement is necessary for crowdfunding success. These results should assist Australian social enterprises to achieve crowdfunding success using proposed combinations of signals suited to their circumstances
Design and Fabrication of Mandibular Implants using Additive Manufacturing Technologies
No full textPatients with mandibular defects need implants that are aesthetically pleasing and functional. Traditional methods of reconstructive surgeries do not provide satisfactory results. The aim of this PhD project was to find optimal solution for both design and fabrication processes of mandibular implants. An accurate and cost-effective mandible implant was designed by developing measurement system which helped determine the medium plane of mandible with the aim of increasing accuracy. The implant was additionally improved by integrating dental implants into the mandibular implant with the aim of surgery time reduction. A platform to evaluate implant's accuracy was developed and Finite Element Analysis was performed on the surgical guide
An examination of climate-related disclosures by Australian listed companies
No full textThis study examined three perspectives related to climate-related disclosures for the study period of 2018-2021. The first aspect is related to the quality of Task Force on Climate-Related Financial Disclosures by companies in four industries (Energy, Transportation, Banking, and Insurance). The second perspective examined discrepancies in the emissions data for Scope 1 and 2 disclosed between the National Greenhouse and Energy Reporting and Carbon Disclosure Project frameworks and corporate annual and sustainability reports. The third perspective addressed the most mentioned carbon offset standards and principles by companies in the four industries. This study highlights the urgent need for action on climate disclosures and the important role that companies, investors, and policymakers must play in promoting greater sustainability and accountability.</p

Developing an integrated e-wallet continuance model for the Malaysian digital economy
No full textThis study investigates the factors influencing e-wallet continuance among consumers and merchants in Malaysia, guided by Expectancy Value Theory (EVT) and extended with transaction-based constructs. Key drivers include intrinsic factors (trust, risk), extrinsic factors (accessibility, seamlessness, innovativeness, government support), mediators (attitude, utilitarian value), and the moderating role of customer engagement. Findings reveal attitudes and perceived benefits as critical for long-term adoption, with managerial implications emphasizing operational efficiency and system integration for merchants. This research provides valuable insights into e-wallet usage and continuance, advancing theoretical understanding, and offering practical recommendations for stakeholders in the digital payment ecosystem.</p
