Using A Multi-Experimental Approach To Assess The Fate Of Angled-And-Released Yellowtail Kingfish (Seriola Lalandi), Lachlan W. Roberts, Paul A. Butcher, Matt K. Broadhurst, Brian R. Cullis

Faculty of Informatics - Papers (Archive)

Yellowtail kingfish (Seriola lalandi) are angled throughout their global distribution and released in large numbers under the unsubstantiatedassumption of few impacts. The validity of this supposition was tested for southeastern Australian stocks. In all, 54 fishwere angled and released into cages with 36 controls and monitored for 5 d. Of the angled fish, 15% died, mostly as a consequenceof gill-hooking and the associated physiological and mechanical damage. A biotelemetry experiment was then performed to determineif cutting the line on gill-hooked fish could improve their post-release fate. The attachment of transmitters was validated in anaquarium experiment before 12 jaw- and 10 …

Automating Dimensional Tolerancing Using Ripple Down Rules (Rdr), Ghassan Beydoun, Achim Hoffmann, Ramsey Hamade

Faculty of Informatics - Papers (Archive)

We propose to use a knowledge based approach to assist in mechanical design focusing on dimensional tolerancing. To illustrate our approach, we capture the knowledge which human designers utilize in order to specify dimensional tolerances on shafts and mating holes in order to meet desired classes of fit as set by relevant engineering standards. The software system we developed would help mechanical designers become more effective in the time-consuming dimensioning and tolerancing process of their designs in the future. In doing this, the paper makes a twofold contribution to the field of knowledge acquisition: firstly, interface was adjusted to receive …

Australian Institute for Innovative Materials - Papers

We investigated on microstructure and superconducting properties of high-density MgB2superconductors synthesized by a heat-treatment method combining a short period of sintering at 1100°C with a following annealing at a low temperature. The two-step sintering method was found to achieve a coexistence of a high density and broadened XRD full width at half maximum (FWHM) of MgB2 peak in the samples. The onset of diamagnetism at 5 T was approximately 2 K higher than those of the samples heat-treated by single-step sintering at high or low temperatures. Different second-step annealing temperatures were examined in this work. …

Kinetic Analysis Of Oleic Acid Esterification Using Lipolytic Enzyme As Catalyst, Mohd S. Mahmud, James W. Ryan, Cyrus Cooper, Tomasz Safinski, Mark I. Nelson, Harvinder S. Sidhu, Soji A. Adesina

Faculty of Informatics - Papers (Archive)

This paper deals with the esterification kinetics of oleic acid (OA) using ethanol (EtOH) over acrylic-supported lipase from Aspergillus niger (Novozym 435) as catalyst. The reaction was carried out in a stirred 500 mL Pyrex glass reactor at 45oC under conditions with negligible external and internal transport resistances. Reaction runs in a microaqueous medium employed OA: EtOH ratio, b, between 0.01 to 2.0 without initial addition of water. The rate dependency on reactant concentration has a maximum at b=0.9, just below the stoichiometric ratio, and was therefore described by a Michaelis- Menten kinetic expression implicating irreversible surface reaction between adsorbed …

Soil redistribution studies are important, especially in water supply catchments, because the rate at which denudation is occurring has implications for offsite water quality. However, the extent to which soil is redistributed within the landscape can be difficult to determine. This challenge can be overcome using fallout caesium-137 (137Cs). This paper describes the rates of soil loss and remobilisation in two sub-catchments within the Sydney Basin region, namely Kembla and Kentish Creeks, which drain to the Cordeaux reservoir. The total inventories of 137Cs in catchment soils were determined, a 137Cs-regression equation and a theoretical diffusion and migration …

Hydrogen chloride (HCl) and hydrogen fluoride (HF) are respectively the main chlorine and fluorine reservoirs in the Earth's stratosphere. Their buildup resulted from the intensive use of man-made halogenated source gases, in particular CFC-11 (CCl3F) and CFC-12 (CCl2F2), during the second half of the 20th century. It is important to continue monitoring the evolution of these source gases and reservoirs, in support of the Montreal Protocol and also indirectly of the Kyoto Protocol. The Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) is a space-based instrument that has been performing regular solar occultation measurements of …

Faculty of Science - Papers (Archive)

This work describes the fabrication of gas sensors using inkjet printing. Sensors were constructed by building up a film of sensing material, such as polyaniline, from aqueous nanoparticulate dispersions. These films were printed over patterned silver interdigitated array designs for the purposes of conductimetric analysis. Unlike screen printing or lithography, inkjet printing does not require stencils or masks, therefore allowing rapid design and prototyping. For this study, polyaniline and modified polyaniline sensors were inkjet printed and assessed for the purposes of gas sensing applications, specifically hydrogen sulfide monitoring.

Reconciling Self: Gay Men And Lesbians Using Domestic Materiality For Identity Management, Andrew W. Gorman-Murray Jan 2007

Reconciling Self: Gay Men And Lesbians Using Domestic Materiality For Identity Management, Andrew W. Gorman-Murray

Faculty of Science - Papers (Archive)

This paper contributes to research on gay/lesbian experiences, meanings and uses of domestic environments by considering the role of domestic materiality in gay/lesbian identity management. Prior work shows that accumulating and arranging meaningful possessions in domestic space underwrites identity work. Drawing on in-depth interviews with gay/lesbian Australians, I apply this contention to gay/lesbian homemaking practices. In particular, conceptualising identity as fractured, I argue that maintaining domestic materiality reconciles diverse dimensions of multi-faceted selves. Different possessions embody different facets of self – sexuality, familial connections, cultural heritage, spiritual beliefs, inter alia. Juxtaposing these objects at home brings together the diverse fragments …


Arbitrary Ratio Sample Rate Conversion Using B-Spline Interpolation For Software Defined Radio, Xiaojing Huang Jan 2006

Arbitrary Ratio Sample Rate Conversion Using B-Spline Interpolation For Software Defined Radio, Xiaojing Huang

Faculty of Informatics - Papers (Archive)

Arbitrary ratio sampling rate conversion (SRC) structure using B-spline interpolation is proposed for software defined radio (SDR) in this paper. By combining SRC with SDR’s transmitter/receiver filter, the constraint on SRC reconstruction filter can be relaxed, and an overall computational reduction can be achieved. The mixed-width B-spline is introduced so that both antiimaging and anti-aliasing requirements for SRC are satisfied. The passband droop introduced by the B-spline interpolation is compensated by a linear phase digital filter incorporated in the SRC structure so that the overall frequency response approaches the desired frequency response of the SDR’s transmitter/receiver filter. To make the …


Secure Data Transmission Using Quibits, Iman Marvian, Saied Hosseini-Khayat Jan 2006

Secure Data Transmission Using Quibits, Iman Marvian, Saied Hosseini-Khayat

Faculty of Informatics - Papers (Archive)

A quantum protocol for secure transmission of data using qubits is presented. This protocol sends one qubit in a round-trip to transmit one bit of data. The protocol offers an improvement over the BB84 QKD protocol. BB84, in conjunction with one-time pad encryption, has been shown to be unconditionally secure. However its security relies on the assumption that the qubit source device does not emit multiple replicas of the same qubit for each transmitted bit. If this happens a multi-qubit emission attack can be launched. In addition, BB84 cannot be used to send predetermined bit strings as it generates a …

Estuaries worldwide are under increasing threat from human impacts. Because much of their fauna remains unstudied and in many cases undescribed, these systems present real challenges for effective management. In eastern Australia the study of estuarine fauna is often further complicated by its patchy distributions. This is particularly the case for assemblages of sessile invertebrates in coastal saline lakes. This study quantified distributions of sponges and ascidians at a hierarchy of spatial scales in the seagrass meadows of 2 coastal saline lakes in New South Wales, Australia. Nine species of sponge, many of which were undescribed, and 3 species of …
