Description: Potassium alkyl xanthates are commonly used as collectors in the flotation of sulphide minerals. Much research has been directed to the formulation of mechanisms responsible for the hydrophobicity of the sulphide minerals in xanthate flotation. Alkyl dixanthogen plays an important role in this mixed-potential mechanism, and is regarded as the species which imparts hydrophobicity to the mineral surface. Winter has recently suggested that sulphur xanthates, which are chemically very similar to alkyl dixanthogen, may play a significant role in the processes rendering the sulphide minerals hydrophobic during froth flotation. The aim of this investigation was to develop techniques for the separation and identification of sulphur xanthates at very low levels of conecentration. Techniques employed were Molecular Emission Cavity Analysis Spectroscopy and High Performance Liquid Chromatography. It was possible to extract the sulpur xanthates from simulated flotation liquors, separate the individual species, and determine them to a level of 0.05 ppm in the liquor. Aklyl sulphur dixanthates were found to disproportionate in methanol solution.

Description: Visualising Ballarat is an ongoing project, currently in the early stages of development. It employs a collaborative research approach for developing state-of-the-art knowledge management and planning tools which will empower various community sectors to understand the urban landscape, recognise cultural significance, and assess and monitor change. It proposes a staged approach to a long-term research project that will result in web-based spatial information systems, which include 3-dimensional and 4-dimensional visualisations together with augmented reality experiences of past, present and future Ballarat city landscapes. In September 2013, Ballarat was the first Australian city to join an international pilot program to implement UNESCO’s Recommendation on the Historic Urban Landscape (HUL). This recognises the role that urban heritage plays as a social, cultural and economic asset in the development of cities. The HUL program vision is to help Ballarat grow without compromising its heritage; by providing a road map on how to address change without losing Ballarat’s character. At the core of the HUL approach are the community's values, which are the starting point for city management. Hence, there is a need to map these values effectively and have all of Council referencing them as a starting point to city development. It is envisaged that Visualising Ballarat will have a much broader appeal than HUL, extending through a full range of uses - from the utilitarian, such as locating old mine workings and landfill sites - to the esoteric, such as immersive augmented reality experiences of historical places or events. The key component is to provide the community, practitioners, researchers and industry with place-based information on demand, and hence encourage a deeper understanding, consideration and appreciation of the city's historic urban landscape values. Federation University Australia's eresearch and digital innovation capability is being utilised to federate HUL information, data and databases to facilitate access to historic urban landscape information. The developing web-based portal will provide easy access to authoritative and credible heritage information for city managers, developers, planners, researchers, communities of interest, groups and agencies wishing to engage in HUL program activities. It will promote the sharing of knowledge and information, allowing people to gain insights, present ideas, advice and information in a friendly and easy-to-use format, available at people’s convenience. It allows the City of Ballarat citizens to grow their knowledge and share their thoughts and enthusiasm for their city's historic urban landscape. In that sense, the website is deliberately aimed in part at supporting ratepayers, citizens and community groups to feel connected and supported in their heritage interests. The longer-term intention is to encourage the generation of research ideas and projects with other collaborators, locally to globally. This discussion paper outlines a collaborative approach which can be regarded as a blueprint for research that will assist the City of Ballarat and Federation University Australia in achieving their shared goals. The proposed research is founded on the 144-year old relationship between the organisations that has resulted in a substantial repository of regional knowledge. Online liberation of this information, together with that held in the other knowledge repositories of long-standing Ballarat institutions, has the potential to provide new insights into the urban landscapes of this historic city. This visualisation, which is stage 1 of the Historic Urban Landscapes Project, starts the process of bringing together community activities, research and data from government, academics and other sources. It includes: A mapping interface that brings together historic and new data about Ballarat's history and landscape Connections to research on Ballarat's history and landscape and the Historic Urban Landscape approach to managing Ballarat A place for researchers to have an internet 'home' for their projects Connections to existing community activities on Ballarat's heritage and landscape Links into the international 'historic urban landscape' community. This is done through the collection and mapping of data which includes historic landscape imagery, heritage places, parks and gardens, natural landscape and character areas, geological features, community infrastructure and a range of regulatory planning tools and administrative boundaries. This visualisation is part of an interoperable web-GIS maintained by the Centre for eResearch and Digital Innovation(CeRDI) at Federation University Australia (FedUni).

Description: The modern digital internet economy and billions of dollars of trade are made possible by the internet security which is provided by operating system and web browser developers. This paper provides a survey of how this security is implemented through the use of digital certificates and the Public Key Infrastructure. Documented cases of the abuse of these digital certificates are given. It is shown that these problems arise from a combination of commercial pressures and a failure of the designers of internet security to consider the fundamental security principal of least privilege. Measures which are used to mitigate these problems are noted and new PKI architectural components which are designed to correct existing problems are examined.

Description: Spectral domain optical coherence tomography (SDOCT) is routinely used in the management and diagnosis of a variety of ocular diseases. This imaging modality also finds widespread use in research, where quantitative measurements obtained from the images are used to track disease progression. In recent years, the number of available scanners and imaging protocols grown and there is a distinct absence of a unified tool that is capable of visualizing, segmenting, and analyzing the data. This is especially noteworthy in longitudinal studies, where data from older scanners and/or protocols may need to be analyzed. Here, we present a graphical user interface (GUI) that allows users to visualize and analyze SDOCT images obtained from two commonly used scanners. The retinal surfaces in the scans can be segmented using a previously described method, and the retinal layer thicknesses can be compared to a normative database. If necessary, the segmented surfaces can also be corrected and the changes applied. The interface also allows users to import and export retinal layer thickness data to an SQL database, thereby allowing for the collation of data from a number of collaborating sites.

Description: The Corangamite Catchment Management Authority Knowledge Base is part of an interoperable web-GIS maintained by Federation University Australia. The site provides an extensive collection of publications and Datasets on all aspects of the catchment. The collection focuses on information written specifically for the Corangamite Region. The database has been indexed by subject and locality for information retrieval and analysis. Federation University Australia's Centre for eResearch and Digital Innovation is hosting the site on behalf of the CCMA. The Federation University Australia Corangamite Catchment Management Authority Knowledge Base was established to ensure the protection and sustainable development of land, vegetation and water resources within a boundary stretching from Geelong to Ballarat and along the coast to Peterborough. About 380,000 people live in the catchment's 13,340 square kilometres of south-western Victoria and 175 kilometres of coastal fringe. The region is defined by four river basins - the Moorabool, Barwon, Lake Corangamite and Otway Coast. It includes all or part of the cities of Ballarat and Greater Geelong, the Borough of Queenscliff and the shires of Moorabool, Surf Coast, Corangamite, Golden Plains, Colac Otway and Moyne. Related initiatives include Soil Health, an online repository of soil health information and knowledge: including reports, research papers, maps and descriptions related to current and past soil series mapping, land capability and suitability assessments, agricultural trials, and soil research and investigations; and, NRM Planning, a pilot project testing how online mapping can be used to match local and regional priorities for catchment management in the Corangamite Catchment Management Authority region.

Description: The Corangamite NRM Planning Portal has been developed to support the creation of local catchment plans in the Corangamite region. It is part of an interoperable web-GIS maintained by Federation University Australia. The Corangamite Catchment Management Authority (CMA), in collaboration with the Centre for eResearch and Digital Innovation(CeRDI) at Federation University Australia (FedUni), the Woady Yaloak Catchment Group (WYCG) and the Surf Coast and Inland Plains Network (SCIPN) is undertaking this pilot project to develop Local Catchment Plans for catchment management in the Corangamite region. This pilot project is testing how online mapping can be used to match local and regional priorities for catchment management in the Corangamite Catchment Management Authority region. The objective is to empower Landcare networks, community groups and stakeholders with the capability to identify ‘joint priorities’ for progressing in partnership. The project also provides access to a considerable knowledge base of spatial data, information and knowledge, to assist stakeholders in setting their local priorities. Project aim The primary aim is to spatially overlay local and regional natural resource management (NRM) priorities to identify ‘joint priorities’ for potential partnership and investment. The initial tasks of developing local priorities was undertaken by the respective Networks and included participation by around 100 community members at each Network to identify 5-6 year Strategic Plans. The collaborators have the common aim of building web-based tools for the CMA community to easily access the most current environmental datasets applicable to integrated catchment management and modelling. The projects promote the sharing of knowledge and information through the internet, allowing people to gain insights, present ideas, advice and information in a friendly and easy to use format, available at people’s convenience. It allows the Corangamite CMA community to grow their knowledge and share their thoughts and enthusiasm for their landscapes. It will also help guide groups and individuals to develop on-ground action plans through the provision of standardised templates and authoritative advice on a range of matters in catchment management, agricultural soil management, nature conservation and on-ground activities.
