Je vais lire un papier très court, rassurez-vous, en anglais et Lachlan, de façon très élégante va lire le sien en français. Et ensuite il m’a proposé que nous fassions un échange en français également. Je m’étais préparé à ce que cela soit en anglais, mais je suis un peu soulagé, je dois le dire, surtout devant de grands spécialistes comme vous. Alors je vais lire mon texte en anglais, je vais ..

L208 Southeast Lachlan Seismic Survey 2018
No full textMaintenance and Update Frequency: asNeededStatement: No lineage availableSix hundred and twenty nine km of deep crustal reflection data were collected for the Southeast Lachlan 2D seismic survey along three transects: 18GA-SL1 (302 km), 18GA-SL2 (163 km) and 18GA-SL3 (164 km) during March to April 2018. The purpose of the survey was to image the Tabberabbera, Omeo, Deddick, Kuark and Mallacoota Zones (west to east) of the Lachlan Orogen at a high angle to their structural grain, as a key reference section for the study of the Palaeozoic geology, geodynamic evolution and mineral potential of Victoria and New South Wales with implications for eastern Australia mineral exploration as well as natural hazard mapping. The Project is a collaboration between Geoscience Australia (GA), the Geological Survey of Victoria (GSV), the Geological Survey of New South Wales (GSNSW), and AuScope. The data processing is being undertaken by a contractor on behalf of GA, GSV, GSNSW and AUScope and is expected to be released in early 2019. <br/><br/><b>Raw data are available on request from [email protected] - Quote eCat# 122684</b>
South East Lachlan Gravity (CSCBA 1VD grid)
No full textMaintenance and Update Frequency: notPlannedStatement: This South East Lachlan Gravity (CSCBA 1VD grid) is the first vertical derivative of the complete spherical cap Bouguer anomaly grid for the South East Lachlan Gravity Survey along Seismic Lines, P201930, Vic, NSW, 2019. This gravity survey was acquired under the project No. 201930 for the geological survey of NSW, VIC. The grid has a cell size of 0.0005 degrees (approximately 50m). A total of 3542 gravity stations at a spacing between 200m and 400m were acquired to produce this grid. Three processes are required to correct the gravity observations for the effects of the surrounding topography: (1) a Bouguer correction (Bullard A), which approximates the topography as an infinite horizontal slab; (2) a correction to that horizontal slab for the curvature of the Earth (Bullard B); and (3) a terrain correction (Bullard C), which accounts for the undulations of the surrounding topography. The complete spherical cap Bouguer gravity anomalies were calculated by applying terrain correction (Bullard C) to the spherical cap Bouguer anomaly point data of South East Lachlan Gravity Survey along Seismic Lines, P201930, Vic, NSW, 2019. These terrain corrections were calculated using software from INTREPID Geophysics. The Intrepid algorithm utilises concentric rings subdivided into cells (Direen, 2001) to calculate the terrain correction. The terrain corrected data were then gridded using a gridding technique provided by the INTREPID Geophysics software package. A first vertical derivative was calculated by applying a fast Fourier transform (FFT) process to the Bouguer gravity grid of the South East Lachlan Gravity Survey along Seismic Lines, P201930, Vic, NSW, 2019 survey to produce this grid. This grid was calculated using an algorithm from the INTREPID Geophysics software package. The processed data are checked by GA geophysicists using standard methods for assessing quality to ensure that the final data are fit-for-purpose. Details of the specifications of individual surveys held in the Australian National Gravity Database (ANGD) can be found in the Second Edition of the Index of Gravity Surveys (Wynne and Bacchin, 2009).

Uses of peer assessment in database teaching and learning
No full textThis discussion paper introduces three very different methods and contexts for the use of peer assessment in introductory database classes, each of which is supported by different learning software tools. In the first case study, at Glasgow Caledonian University, Contributing Student Pedagogy is used, where students contribute to the learning of others through the collaborative creation of a bank of self-assessment questions. This is supported by the Peerwise software tool. Secondly, at the University of Strathclyde, students undertake formative assessment of others in providing feedback on an initial element of a larger coursework assessment. A number of virtual learning environments (VLEs) are capable of supporting this method through customisable discussion fora. Finally, at the University of Abertay Dundee, peer and self assessment are used in a group project to adjust the group grade for individual students. This is effected through the use of the WebPA software tool
Portable form filling assistant for the visually impaired
No full textThe filling of printed forms has always been an issue for the visually impaired. Though optical character recognition technology has helped many blind people to ‘read’ the world, there is not a single device that allows them to fill out a paper-based form without a human assistant. The task of filling forms is however an essential part of their daily lives, for example, for access to social security or benefits. This paper describes a solution that allows a blind person to complete paper-based forms, pervasively and independently, using only off-the-shelf equipment including a Smartphone, a clipboard with sliding ruler, and a ballpoint pen. A dynamic color fiduciary (point of reference) marker is designed so that it can be moved by the user to any part of the form such that all regions can be “visited”. This dynamic color fiduciary marker is robust to camera focus and partial occlusion, allowing flexibility in handling the Smartphone with embedded camera. Feedback is given to the blind user via both voice and tone to facilitate efficient guidance in filling out the form. Experimental results have shown that this prototype can help visually impaired people to fill out a form independently
Making a financial time machine:a multitouch application to enable interactive 3-D visualization of distant savings goals
No full textFinancial planning and decision making for the general public continues to vex and perplex in equal measure. Whilst the tools presented by a typical desktop computer should make the task easier, the recent financial crisis confirms the increasing difficulty that people have in calculating the benefits of deferring consumption for future gains (i.e. Saving). We present an interactive concept demonstration for Microsoft SurfaceTM that tackles two of the key barriers to saving decision making. Firstly we show an interface that avoid the laborious writing down or inputting of data and instead embodies the cognitive decision of allocation of resources in a physical gesture based interface, where the scale of the investment or expenditure correlates with the scale of the gesture. Second we show how a fast-forward based animation can demonstrate the impact of small increments in savings to a long term savings goal in a strategy game-based, interactive format. The platform uses custom software (XNATM format) as opposed to the more usual WPFTM format found on Surface applications. This enables dynamic 3-D graphical icons to be used to maximize the interactive appeal of the interface. Demonstration and test trial feedback indicates that this platform can be adapted to suit the narrative of individual purchasing decisions to inform educate diverse user groups about the long term consequences of small financial decisions
Incremental Observer Relative Data Extraction
No full text The visual exploration of large databases calls for a tight coupling of database and visualization systems. Current visualization systems typically fetch all the data and organize it in a scene tree that is then used to render the visible data. For immersive data explorations in a Cave or a Panorama, where an observer is data space this approach is far from optimal. A more scalable approach is to make the observer-aware database system and to restrict the communication between the database and visualization systems to the relevant data. In this paper VR-tree, an extension of the R-tree, is used to index visibility ranges of objects. We introduce a new operator for incremental Observer Relative data Extraction (iORDE). We propose the Volatile Access STructure (VAST), a lightweight main memory structure that is created on the fly and is maintained during visual data explorations. VAST complements VR-tree and is used to quickly determine objects that enter and leave the visibility area of an observer. We provide a detailed algorithm and we also present experimental results that illustrate the benefits of VAST
Investigating the future of self-service technology
No full textIn this paper we describe an ongoing research project between NCR Dundee and Abertay University to investigate the future of self-service technology for entertainment. The aim was to assess how future technologies may be utilized in building a new system or improving current approaches to content distribution. We designed a web-based survey to determine the likelihood with which users would interact with future services. The findings suggested a strong preference for internet based technologies and the implications for further usage technologies are discussed
