New Music Audiences: The Generative Impulse, David Tham Nov 2010

New Music Audiences: The Generative Impulse, David Tham

Research outputs pre 2011

This paper looks at how the net neutrality debate relates to the music recording industry and considers how new media audiences consume music as social experience and with generative impulse. As the Internet appears to force the music recording industry to re-evaluate its function and change its approach to distributing music and making money, music artistes seem to no longer need to rely on ‘record deals’ to launch or build a music career; and music audiences no longer have to rely on Top-40 radio to be told what is popular listening. This phenomenon has serious implications for new and emerging …


E-Partnerships: Library Information Acquisition In The Comfort Of Students’ Digital Homes, Julia Gross, Eva Dobozy Jan 2010

E-Partnerships: Library Information Acquisition In The Comfort Of Students’ Digital Homes, Julia Gross, Eva Dobozy

Research outputs pre 2011

This paper presents a case study of how a university lecturer and a faculty librarian built upon their shared concerns about first-year students’ lack of information literacy. It describes in some detail their underlying beliefs, which led to this experimental intervention design and the strategic e-partnership. Embedded library podcasts were used to push library information to students. The potential and actual impact of this e-partnership on personalised support for a diverse student body is explored and an argument is presented for e-partnerships among university staff in an effort to better assist first-year higher education students.


Redtnet: A Network Model For Strategy Games, Philip Hingston, Mike Preuss, Daniel Spierling Jan 2010

Redtnet: A Network Model For Strategy Games, Philip Hingston, Mike Preuss, Daniel Spierling

Research outputs pre 2011

In this work, we develop a simple, graph-based framework, RedTNet, for computational modeling of strategy games and simulations. The framework applies the concept of red teaming as a means by which to explore alternative strategies. We show how the model supports computer-based red teaming in several applications: realtime strategy games and critical infrastructure protection, using an evolutionary algorithm to automatically detect good and often surprising strategies.

Opto-Vlsi-Based Tunable Linear-Cavity Fibre Laser, David Michel, Feng Xiao, Kamal Alameh

Research outputs pre 2011

A novel approach using an Opto-VLSI processor to achieve a tunable fibre laser is presented. The Opto-VLSI based fibre laser is able to tune wavelengths and maintain a high Side-Mode Suppression Ratio (SMSR) even when the output optical power is low. Experimental results show a continuously tunable fibre laser source with a tuning range as high as 30 nm and a SMSR exceeding 30 dB.


Pspice Simulation Of An Electro-Acoustic Communications Channel, Graham Wild, Steven Hinckley Jan 2010

Pspice Simulation Of An Electro-Acoustic Communications Channel, Graham Wild, Steven Hinckley

Research outputs pre 2011

In this paper, we present results from a circuit simulation of a proposed electro-acoustic communications channel. The communications channel was modeled in PSpice using Redwood's version of Mason's equivalent circuit. The simulations used binary phase shift keyed communications signals with a carrier frequency of 1.12 MHz. Results obtained from the model are comparable with the results obtained experimentally. The frequency response of the model matched the measured frequency response, predicting lower frequency resonances obtained in the experimental data. The transient response of the model compares almost identically with the transient response observed experimentally. This is a significant characteristic as the …

Light Reductions Drive Macroinvertebrate Changes In Amphibolis Griffithii Seagrass Habitat, Adam Gartner, Paul S. Lavery, Kathryn Mcmahon, Anne Brearley, Helen Barwick

Research outputs pre 2011

Numerous anthropogenic activities can significantly reduce the amount of light reaching seagrass habitats. Typically these result in morphological and physiological changes to the plant and associated algal epiphytes. However, the flow-on effects to seagrass-dependent fauna induced by these disturbances has yet to be examined. This study investigated the effects of different light reduction intensity (high: ~92% reduction; moderate: ~84% reduction), duration (3, 6 and 9 mo) and timing (post-winter and post-summer) on the density and biomass of macroinvertebrate epifauna within an Amphibolis griffithii seagrass ecosystem (Western Australia). There were generally lower epifauna densities and biomass within shaded seagrass plots. When …

Android Forensics: Simplifying Cell Phone Examinations, Jeff Lessard, Gary Kessler

Research outputs pre 2011

It is hardly appropriate to call the devices many use to receive the occasional phone call a telephone any more. The capability of these devices is growing, as is the number of people utilizing them. By the end of 2009, 46.3% of mobile phones in use in the United States were reported to be smart phones (AdMob, 2010). With the increased availability of these powerful devices, there is also a potential increase for criminals to use this technology as well. Criminals could use smart phones for a number of activities such as committing fraud over e-mail, harassment through text messages, …

Caviar And The Australian Stock Markets : An Appetiser, David E. Allen, A. K. Singh

Research outputs pre 2011

Value-at-Risk (VaR) has become the universally accepted metric adopted internationally under the Basel Accords for banking industry internal control and for regulatory reporting. This has focused attention on methods of measuring, estimating and forecasting lower tail risk. One promising technique is Quantile Regression which holds the promise of efficiently calculating (VAR). To this end, Engle and Manganelli in (2004) developed their CAViaR model (Conditional Autoregressive Value at Risk). In this paper we apply their model to Australian Stock Market indices and a sample of stocks, and test the efficacy of four different specifications of the model in a set of …

Turban Snails As Habitat For Foliose Algae: Contrasting Geographical Patterns In Species Richness, Thomas Wernberg, Fernando Tuya, Mads Thomsen, Gary Kendrick

Research outputs pre 2011

Understanding patterns of species richness is a major goal for ecologists, especially in space-limited habitats where many organisms live on top of others (epibiosis, e.g. by algae growing on gastropods in marine environments). We tested the hypotheses that species richness of epiflora on the gastropod Turbo torquatus would not differ between regions with similarly rich algal floras, and that epifloral richness would increase with increasing gastropod size. Macroalgal floras of Hamelin Bay (HB), Marmion (M), Jurien Bay (JB) and Kalbarri (K), Western Australia, ranged from ~20 to 40 species reef–1 (JB = HB = M ≥ K). Epiflora on small …

Design Of Functionally Graded Carbon Coatings Against Contact Damage, Rajnish K. Singh, Zhifeng Zhou, Lawrence Kwok Yan Li, Paul Munroe, Mark Hoffman, Zonghan Xie

Research outputs pre 2011

Three different functionally graded amorphous carbon (a-C) thin films were deposited on to aluminium substrates using a closed-field unbalanced magnetron sputtering ion plating method. The closed-field configuration prohibits the loss of secondary electrons and consequently enhances the plasma density significantly. The functional gradient of the a-C films was achieved by varying the bias voltage linearly during deposition. Three graded a-C systems possessing different variations in Young's modulus were deposited with the highest Young's modulus at the (i) top surface, (ii) interface or (iii) middle of the film. Of the three systems investigated, the one with the highest Young's modulus at …

Research outputs pre 2011

Satiety is important in regulating food intake and has important public health significance in the control of obesity. Food containing protein and non-starch polysaccharides provides a satiety effect through various mechanisms but a comparison of the satiety effect on each has not previously been investigated. This study compared the satiety effect or reduction of hunger after consumption of (i) a whey proteinbased drink versus an alginate-based drink of the same viscosity where only the protein content differed, (ii) two alginate-based drinks differing in alginate type and viscosity, and (iii) a whey protein-based drink versus an alginate-based drink differing in protein …


Funding And Secondary School Choice In Australia: A Historical Consideration, Rosemary Cahill, Jan Gray Jan 2010

Funding And Secondary School Choice In Australia: A Historical Consideration, Rosemary Cahill, Jan Gray

Research outputs pre 2011

Since public funds first began to flow into non-government schools in the mid-1970s, successive Commonwealth and state governments have steadily increased the amount of funding they have provided to nongovernment schools (Bonnor & Caro, 2007; Macfarlane, 2003). The outcome of this funding decision has brought the cost of a ‘private school education’ within reach of many more Australian families in the 21st century (Rothman, 2003; Symes & Gulson, 2005). This paper explores the historical backdrop within which secondary schooling is provided in Western Australian today in order to better understand how it influences and/or predisposes the secondary school choices currently …

Autonomous Bee Colony Optimization For Multi-Objective Function, F Zeng, James Decraene, Malcolm Low, Philip Hingston, C Wentong, Z Suiping, M Chandramohan

Research outputs pre 2011

An Autonomous Bee Colony Optimization (A-BCO) algorithm for solving multi-objective numerical problems is proposed. In contrast with previous Bee Colony algorithms, A-BCO utilizes a diversity-based performance metric to dynamically assess the archive set. This assessment is employed to adapt the bee colony structures and flying patterns. This self-adaptation feature is introduced to optimize the balance between exploration and exploitation during the search process. Moreover, the total number of search iterations is also determined/optimized by A-BCO, according to user pre-specified conditions, during the search process. We evaluate A-BCO upon numerical benchmark problems and the experimental results demonstrate the effectiveness and robustness …

A New Design For A Turing Test For Bots, Philip Hingston

Research outputs pre 2011

Interesting, human-like opponents add to the entertainment value of a video game, and creating such opponents is a difficult challenge for programmers. Can artificial intelligence and computational intelligence provide the means to convincingly simulate a human opponent? Or are simple programming tricks and deceptions more effective? To answer these questions, the author designed and organised a game bot programming competition, the BotPrize, in which competitors submit bots that try to pass a “Turing Test for Bots”. In this paper, we describe a new design for the competition, which will make it simpler to run, and, we hope, open up new …

Research outputs pre 2011

Background/aims Ageing of the population will result in unprecedented numbers of older adults living with age-related vision loss (ARVL). Self-management models improve health outcomes and reduce healthcare costs; however, the principles have rarely been applied in low vision services. Methods A two-armed randomised controlled trial of older adults (n=77) with ARVL compared ‘usual care’ provided by a not-for-profit community agency with an extended model of care (usual care+self-management group intervention). The primary outcome variable (participation in life situations) was measured using the Activity Card Sort. Secondary outcome measures examined general health and vision-specific domains. Results The intention-to-treat analysis demonstrated that …

Research outputs pre 2011

Background The low-density lipoprotein receptor related protein 1 (LRP1) has been implicated in Alzheimer's disease (AD) but its signalling has not been fully evaluated. There is good evidence that the cytoplasmic domain of LRP1 is involved in protein-protein interactions, important in the cell biology of LRP1. Results We carried out three yeast two-hybrid screens to identify proteins that interact with the cytoplasmic domain of LRP1. The screens included both conventional screens as well as a novel, split-ubiquitin-based screen in which an LRP1 construct was expressed and screened as a transmembrane protein. The split-ubiquitin screen was validated in a screen using …
