    Conference Paper
    Challenges like population growth and climate change are maintaining a high level of dynamism in the water industry, resulting in large capital investments and the consideration of alternatives to conventional water supplies. In this environment, LCA is appreciated as a useful planning tool, but it has not yet achieved its full potential due to the lack of a national sustainability framework and other factors. In this paper, examples of recent LCAs in the water industry are discussed. The practical justification and resourcing of LCAs are examined. In addition, two case studies are presented illustrating how LCA can assist the planning process and the degree to which hybridisation presents a methodological challenge to traditional process LCA. Finally, the implications of the new WSAA Sustainability Framework for the future of LCA practice are discussed.

    Conference Paper
    The topics of ACUN-5 will cover all aspects of the science and technology of composite materials, from materials fabrication, processing, manufacture, structural and property characterisation, theoretical analysis, modelling and simulation, materials design to a variety of applications, such as aerospace, automotive, infrastructure, packaging, ship-building, and recreational products. ACUN-5 will bring together the latest research and developments of the complete range of composite materials, including biocomposites, medical-composites, functional and smart composites, gradient and layered composites, nanocomposites, structural composites and mimicking natural materials. The reinforcements will range from nano-, micro-, meso- to macro-scale in polymer, metal, ceramic and cementitious matrices.

    Conference Paper
    Audio Nomad comprises a series of cross-disciplinary art/science projects working on the concept of GPS-driven location-based audio applications. Project outcomes in the form of artworks enable a user or audience to experience a virtual audio world situated within the real world, as a spatial composition of sounds seeming to originate from real objects. Two-dimensional audio spatialization simulates realistic sound sources, and non-spatialized sounds may also be used as location-based content. Conceptually, sound is used to reveal information or create an aesthetic, often composed of a combination of oral histories, archival audio, site-specific historical information, field recordings, and music. The outcome is a culturally significant public sound artwork utilizing this new location-based audio medium – an application of global positioning, audio technologies, and software engineering. As GNSS technologies become more ubiquitous, Audio Nomad can take advantage of new platforms such as mobile phones. This unique multidisciplinary collaboration has driven the design of tools with great creative potential to provide new alternative location-based services poised to engage and appeal to the imagination of future GNSS users.

    Conference Paper
    Fibre Bragg grating (FBG) sensors are used for the experimental investigation of two of the most important time-dependent properties of concrete: drying shrinkage and creep. A swept wavelenght system is used as the interrogation technique. The FBG sensors are embedded directly into structural grade concrete specimens. Standard mechanical method is used in parallel with embedded FBG sensors. Both mechanically and optically measured time-dependent strains are discussed. It is shown that the FBG sensors offer a better alternative to the conventional electrical and mechanical methods, in the measurement of long-term time-dependent strains.
