http://espace.library.uq.edu.au/view/UQ:179869; One of the fastest and most performing tools on Web 2.0 is RSS (Really Simple Syndication). It allows the access to digital content without constantly visiting the pages where it is stored. Syndication enables to share all kind of information in XML format, and offers us the opportunity of showing our own content in other web pages in an integrated way, giving an added value to the information. In this communication we would like to present a Network Collaborative Project between medical libraries belonging to different institutions, located in different geographical areas and with different purposes, objectives and interests (some of them focusing on research and teaching and other on medical practice). Our medical libraries have incorporated “the content syndication”, on the one hand, as another tool for medical librarian work and, on the other hand, as a value-added service in order to be useful to different users such as medical staff, teachers, researchers or students. RSS lets us share information channels, creating a space for collaborative research. Syndication is a great help to our users as it develops a new trend in the content management sector, which is changing considerably the relationship with information...

This document records the process of migrating eprints.org data to a Fez repository. Fez is a Web-based digital repository and workflow management system based on Fedora (http://www.fedora.info/). At the time of migration, the University of Queensland Library was using EPrints 2.2.1 [pepper] for its ePrintsUQ repository. Once we began to develop Fez, we did not upgrade to later versions of eprints.org software since we knew we would be migrating data from ePrintsUQ to the Fez-based UQ eSpace. Since this document records our experiences of migration from an earlier version of eprints.org, anyone seeking to migrate eprints.org data into a Fez repository might encounter some small differences. Moving UQ publication data from an eprints.org repository into a Fez repository (hereafter called UQ eSpace (http://espace.uq.edu.au/) was part of a plan to integrate metadata (and, in some cases, full texts) about all UQ research outputs, including theses, images, multimedia and datasets, in a single repository. This tied in with the plan to identify and capture the research output of a single institution, the main task of the eScholarshipUQ testbed for the Australian Partnership for Sustainable Repositories project (http://www.apsr.edu.au/). The migration could not occur at UQ until the functionality in Fez was at least equal to that of the existing ePrintsUQ repository. Accordingly...

The higher education and professional environments have been transformed for the last 20 years by the digital publishing revolution. Electronic resources and open access repositories are now part of research and professional tools. Herein the writer describes his experience with institutional open access repositories, and some implications in terms of research, impact and quality in civil engineering. It is critical to appreciate that civil engineering is not a "virtual" science, and that the digital "band-aids" do not replace scholarship, personal experience and smart thinking.; Paper and presentation given by Hubert Chanson, University of Queensland, at APSR Open Access Collections, 14 February 2008, Customs House, Brisbane.

A two part optimisation study using the computer search technique of Genetic Algorithm optimisation has been carried out for the Gold Coast area. The study covered ten water supply zones from Nerang South to Coolangatta. Part one of the study focussed on three water supply zones. The Optimatics Genetic Algorithm (OGA) was used to optimise pipe sizes, zone boundary locations and storage sizes that satisfied Gold Coast Water’s (GCW) hydraulic constraints whilst dramatically reducing the cost of the augmentations to the system. Part two focussed on the transmission mains for all ten water supply zones in the area. The OGA was able to optimise pipe sizes, pump sizes and valve settings to satisfy the GCW tank refill, node pressures and pipe velocity criteria, whilst again reducing the overall cost of the required augmentations to the system.; http://espace.library.uq.edu.au/view/UQ:111555; Andrew J.

The existence of uncertainties in water distribution systems (WDSs) has been recognised for several decades within the literature (typical examples of uncertainty include demand variability, component failures and increased roughness of pipes). The existence of these uncertainties implies that the risk of inadequate hydraulic performance needs to be identified and assessed throughout the system. In this paper, the risk of hydraulic failure of an existing WDS is assessed, both in terms of reliability (probability of non-failure) and vulnerability (probable magnitude of failure given that a failure has occurred). The WDS considered within this paper is the McLaren Vale/McLaren Flat system, which is located approximately 30 km to the south of Adelaide, South Australia. The spatial variability of both reliability and vulnerability is modelled and the results are presented using spatial contour maps. The results indicate that such maps are extremely useful for identifying and interpreting critical regions and regions of poorer performance in terms of pressure head. Furthermore, by using both reliability and vulnerability indices, a more complete description of risk, using the multiple criteria, is obtained.; http://espace.library.uq.edu.au/view/UQ:111555; Michael Leonard...

Abstract: Plasticity induced crack closure and constraint effects due to finite plate thickness are both fundamental aspects in the mechanics of fatigue cracks. Moreover, plasticity induced crack closure provides an effective first-order correction to the crack driving force, as used in the correlation and prediction of fatigue crack growth. The approach developed in this study utilises the distributed dislocation technique to model fatigue cracks growing under constant amplitude loading in finite thickness plates. Numerical results are obtained through the application of Gauss-Chebyshev quadrature and are presented for the crack opening stress ratio. An excellent agreement is observed with previous three-dimensional finite element studies.; http://espace.library.uq.edu.au/view/UQ:131835; John Codrington and Andrei Kotousov

The amount of mercury in the wastewater of three dental clinics from United Arab Emirates over a period of 3 to 17 days was quantified using cold vapour-atomic absorption spectrometry technique. The total Hg concentration in the wastewater of these clinics ranged from 25 to 146 μg d-1. The Hg concentration in the wastewater samples collected from the outlets of the dental chairs after dental treatments varies depending on the type of dental treatment: the average Hg concentration in the samples of only amalgam restoration is 39 μg per sample (std. dev. 37, range 4-142); for samples with amalgam restoration plus other types of dental treatment is 24 μg per sample (std. dev. 24, range < MDL-77); and for sample with no amalgam restoration is 18 μg per sample (std. dev. 16, range; http://espace.library.uq.edu.au/view/UQ:166849; Sausan Al Kawas, Imad A.

Numerical experiments are conducted on the velocity field on the Oseen vortex to determine the effect of random errors in the velocity field on the circulation estimate. The circulation is estimated by either a velocity integral or a vorticity integral over a particular region of integration. A novel method for the determination of this region is used. The accuracy of circulation estimation schemes is characterised in terms of the velocity sample spacing, the amount of random noise in the velocity field and the vorticity estimation scheme used. It is found that, in general, the velocity integral outperforms the vorticity integral in terms of reducing total error; http://espace.library.uq.edu.au/view.php?pid=UQ:120763; E. R. Hassan, T. C. W.

The flow around an unsteady hydrofoil, undergoing simultaneous heaving and pitching motions which mimic the tail motions of carangiform fish (such as tuna), was investigated using simultaneous particle image velocimetry (PIV) and force measurement. These investigations were performed at Reynolds numbers, based on the foil chord length, in the range of 1500 < Re < 12500. The Strouhal numbers, based on the foil heave amplitude, were in the range of 0.1 < Sth < 0.95. Hydrogen bubble visualisation was also performed on the foil at identical Sth, but at 500 < Re < 3500. Two force measurements were obtained. Firstly, instantaneous thrust and side forces were obtained by direct strain gauge measurements on the foil, which were then time-averaged. Secondly, time-averaged thrust forces were estimated using a momentum Integral around the time-averaged two-dimensional PIV velocity field around the foil. Both force measurements, which show excellent agreement for all foil parameters, indicate that the foil is able to produce very large thrust coefficients, Ct , in excess of 10. These large thrust coefficients typically occur when the non-dimensional foil heave amplitude is large, at conditions where hydrogen bubble visualisation indicates that large leading edge vortices are generated. This suggests that the unsteady foil may be able to use unsteady flow mechanisms to generate large forces.; http://espace.library.uq.edu.au/view/UQ:121132; Timothy C. W. Lau and Richard M. Kelso

The purpose of this study is to determine the aeroacoustic and fluid-dynamic nature of the flow field in and around a generic aircraft cavity in order to characterise the physical mechanism of noise and vibration generated by the flow. This paper discusses the experimental investigation of a narrow, shallow, rectangular cavity in both wind and water tunnel facilities. The experimental investigation primarily focuses on boundary layer characteristics, surface pressure distributions and surface flow visualisation. Qualitative and quantitative results are discussed. This paper reports results for cavities of length:depth:width ratios of 6:1:2. The principal findings are in agreement with an "open" type flow as stated in the literature, however the flow within the cavity is highly three-dimensional in contrast with the suggestions of Stallings & Wilcox (1987). Significant three-dimensionality is also evident downstream of the cavity, close to the training edge. Further findings suggest the shear layer impinges below the edge of the rear wall in the mean, leading to a net inflow of free-stream fluid into the cavity at the centre line, which is balanced by an outflow adjacent to the side walls. Finally, a number of vortices are present at the rear wall...

A nozzle consisting of an abrupt expansion into a short open- ended tube can produce a naturally-excited oscillating-jet flow. The characteristics of the oscillating jet depend on jet-orifice to chamber expansion ratio (D/d1), chamber length-to-diameter ratio (L/D), and shape of the jet orifice. In experiments using water as a flow medium, air-bubble visualisation and signals from a pressure transducer show that a triangular-jet orifice produces aperiodic oscillation without a spectral peak. In contrast, oscillation of the circular jet has clearly visible periodicity and the spectrum has a broad peak. The circular and triangular orifices produce completely different dependence of Strouhal number on expansion ratio. For a circular orifice, Strouhal number is inversely proportional to (D/d1−1). For a triangular orifice, Strouhal number is directly proportional to (D/d1−1). The two curves intersect at an expansion ratio of 4.8, which is approximately the minimum possible expansion ratio for a circular oscillating jet.; http://espace.library.uq.edu.au/view.php?pid=UQ:120835; S.

A jet flow from a triangular-inlet orifice can be made to oscillate or “precess” by partially confining it with a short cylindrical chamber. However, for a narrow range of chamber lengths, the jet is deflected but does not oscillate. Earlier flow-visualisation experiments with this stationary-deflected triangular jet (SDTJ) have revealed a complex flow pattern inside the chamber. The aim of this study is to discover by conditional averaging if there is a similar flow pattern in the fully oscillating jet flow. A backward-facing pressure probe placed in the reattaching flow region of the chamber surface is used as a detector of jet-flow oscillation. With the signal from this detector and simultaneous wall-pressure measurements, we have obtained conditionally-averaged pressure distributions on the wall of the oscillating-triangular-jet (OTJ) nozzle. The OTJ surface pressure distributions have the same features as the time averaged SDTJ surface-pressure distribution, and so the inferred OTJ surface-flow topology has the same features as the SDTJ. However, for the OTJ, the chamber is twice as long, and the conditionally-averaged pressure distribution is much more asymmetrical about a mirror plane drawn through the axis of the nozzle and the detector probe. We conclude that the net radial force due to the asymmetric pressure distribution is large enough to produce significant deflection of the OTJ flow in directions normal to the chamber axis.; http://espace.library.uq.edu.au/view.php?pid=UQ:120837; S.

A nozzle consisting of a circular inlet orifice and a short chamber with an exit lip can produce a naturally oscillating jet flow if the expansion ratio from inlet to chamber (D/d1) is larger than five. As an industrial natural-gas burner, the device offers advantages over simple nozzles of equivalent capacity. However, its usefulness as a pulverised solid-fuel burner is constrained because it requires a high supply pressure. This is due to the high energy-loss coefficient of the inlet expansion ratio, D/d1. If an equilateral-triangular inlet replaces the circular inlet, oscillating flow occurs at equivalent expansion ratios as low as D/d1¼2, and the supply pressure is much lower. An engineering model of the loss coefficient is obtained from measurements of supply pressure over a wide range of nozzle geometries. To begin, we split the overall loss coefficient K into three components, one for each of the inlet oriffice, chamber and exit lip. A formula representing each component of K is then determined from dimensional analysis, inspection of the data, and least-squares curve fitting. Combining these component formulae gives K as a function of four geometric parameters and seven numerical coefficients. When the numerical coefficients are optimised simultaneously...
