Magnetopolaron Interactions In N-Type Indium Phosphide, R. A. Lewis, P. E. Simmonds, Y. J. Wang Dec 2005

Magnetopolaron Interactions In N-Type Indium Phosphide, R. A. Lewis, P. E. Simmonds, Y. J. Wang

Faculty of Engineering - Papers (Archive)

Broadband far-infrared absorption spectroscopy is used to investigate n-type indium phosphide in magnetic fields of up to 30 T. The large energy range 2–14 Ry and the large magnetic field range 03 employed permit the observation of a rich variety of magnetopolaron interactions. We report on the magnetopolaron effect for bound states in InP, beginning with the coupling of the 2p+ state with the 1s+LO phonon state. We further observe the magnetopolaron effect associated with the metastable state 210. In addition we report i) the re-emergence of the 210 impurity state transition beyond the LO phonon manifold, ii) the possible …

Measurements Of Trace Gas Emissions From Australian Forest Fires And Correlations With Coincident Measurements Of Aerosol Optical Depth, Clare Paton-Walsh, N. B. Jones, Stephen R. Wilson, V Haverd, A. Meier, D. W. Griffith Dec 2005

Measurements Of Trace Gas Emissions From Australian Forest Fires And Correlations With Coincident Measurements Of Aerosol Optical Depth, Clare Paton-Walsh, N. B. Jones, Stephen R. Wilson, V Haverd, A. Meier, D. W. Griffith

Faculty of Science - Papers (Archive)

We present vertically integrated measurements of C2H2, C2H4, C2H6, HCOOH, CO, H2CO, HCN and NH3 through smoke plumes from Australian forest fires measured by ground-based solar absorption spectroscopy. The column amounts of these gases are highly correlated with simultaneous, co-located measurements of aerosol optical depth, providing a potential method of mapping biomass-burning emissions using satellite measurements of aerosol optical depth. We have calculated emission ratios relative to CO for the trace gases using aerosol optical depth as a proxy for CO and converted to emission factors by using an average emission factor for CO from literature measurements of extra-tropical forest …

Reflections Of Active Galactic Nucleus Outbursts In The Gaseous Atmosphere Of M87, W. Forman, P. Nulsen, S. Heinz, F. Owen, J. Eilek, A. Vikhlinin, M. Markevitch, R. Kraft, E. Churazov, C. Jones Dec 2005

Reflections Of Active Galactic Nucleus Outbursts In The Gaseous Atmosphere Of M87, W. Forman, P. Nulsen, S. Heinz, F. Owen, J. Eilek, A. Vikhlinin, M. Markevitch, R. Kraft, E. Churazov, C. Jones

Faculty of Engineering - Papers (Archive)

We combined deep Chandra, ROSAT HRI, and XMM-Newton observations of M87 to study the impact of active galactic nucleus (AGN) outbursts on its gaseous atmosphere. Many X-ray features appear to be a direct result of repetitive AGN outbursts. In particular, the X-ray cavities around the jet and counterjet are likely due to the expansion of radio plasma, while rings of enhanced emission at 14 and 17 kpc are probably shock fronts associated with outbursts that began 1–2 × 107 yr ago. The effects of these shocks are also seen in brightenings within the prominent X-ray arms. On larger scales, ∼50 …

Strong Terahertz Emission From (100) P-Type Inas, Rajind Mendis, M. L. Smith, L. J. Bignell, R. Vickers, R. A. Lewis Dec 2005

Strong Terahertz Emission From (100) P-Type Inas, Rajind Mendis, M. L. Smith, L. J. Bignell, R. Vickers, R. A. Lewis

Faculty of Engineering - Papers (Archive)

Terahertz emission has been observed from (100) Zn-acceptor-doped InAs under illumination by fs pulses of near-infrared radiation. Turning the crystal about the surface normal produces two maxima per rotation, whether the angle of incidence is 45° or 75°, in contrast to (111) p-InAs, where three maxima per rotation have been reported. The emitted terahertz power has a quadratic variation with the pump power and decreases with increasing temperature in the range 20–300 K. This behavior is consistent with a photocurrent surge being the dominant terahertz generating mechanism at low excitation fluences. The p-type InAs generates about two orders of magnitude …

Monitoring Structural Degradation Of Rail Pads In Laboratory Using Impact Excitation Technique, S. Kaewunruen, Alexander Remennikov Dec 2005

Monitoring Structural Degradation Of Rail Pads In Laboratory Using Impact Excitation Technique, S. Kaewunruen, Alexander Remennikov

Faculty of Engineering - Papers (Archive)

In ballasted railway track, the deterioration of a sleeper and ballast support usually occurs due to both regular and irregular wheel/rail interactions. The repeated impact of train wheels over sleepers can reduce the lifetime of a sleeper and degrade ballast. To attenuate the effect of the impact loads on concrete sleepers, the resilient rail seat pads are used. After a certain time in service conditions, the worn rail pads have to be replaced. Assessment of the condition of rail pads is of great importance to track engineers and plays an important role in the overall track maintenance cost. A non-destructive …

Simple Implementations Of Mutually Orthogonal Complementary Sets Of Sequences, Xiaojing Huang

Faculty of Informatics - Papers (Archive)

This paper presents simple software and hardware implementations for a class of mutually orthogonal complementary sets of sequences based on its closed-form construction formula. Following a brief review of the Golay-paired Hadamard matrix concept, the flow graph for constructing mutually orthogonal Golay-paired Hadamard matrices, which represent the scalable complete complementary sets of sequences, is proposed. Then, their superb scalability and completeness are summarized. Finally, the C and Matlab functions and a logic schematic diagram are given to easily generate these complementary sequences.

A Fast Neural-Based Eye Detection System, Fok Hing Chi Tivive, Abdesselam Bouzerdoum Dec 2005

A Fast Neural-Based Eye Detection System, Fok Hing Chi Tivive, Abdesselam Bouzerdoum

Faculty of Informatics - Papers (Archive)

This paper presents a fast eye detection system which is based on an artificial neural network known as the shunting inhibitory convolutional neural network, or SICoNNet for short. With its two-dimensional network architecture and the use of convolution operators, the eye detection system processes an entire input image and generates the location map of the detected eyes at the output. The network consists of 479 trainable parameters which are adapted by a modified Levenberg-Marquardt training algorithm in conjunction with a bootstrap procedure. Tested on 180 real images, with 186 faces, the accuracy of the eye detector reaches 96.8% with only …

Fringe Pattern Profilometry Based On Inverse Function Analysis, Y. Hu, Jiangtao Xi, Enbang Li, Joe F. Chicharo, Zongkai Yang Dec 2005

Fringe Pattern Profilometry Based On Inverse Function Analysis, Y. Hu, Jiangtao Xi, Enbang Li, Joe F. Chicharo, Zongkai Yang

Faculty of Informatics - Papers (Archive)

In this paper, we proposed a new algorithm, referred to as inverse function analysis (IFA) method based on the derived mathematical model to reconstruct 3-D surfaces using fringe pattern profilometry (FPP) technique. Compared with traditional methods, our algorithm has neither the requirement for the structure of projected fringe patterns, nor the prior knowledge of the characteristics of projection systems. The correctness of inverse function analysis (IFA) method has been confirmed by simulation results. It can be seen that the measurement accuracy has been significantly improved by inverse function analysis (IFA) method, especially when the expected sinusoidal fringe patterns are distorted …

On 26 December 2004, the largest earthquake for more than 4 decades (magnitude 9.0) occurred between the Australian and Eurasian plates in the Indian Ocean (along the overly stressed Sunda trench) to the west of Aceh Province (Northern Sumatra). The quake triggered a series of waves that increased in height rapidly close to the shore (tsunami) spreading thousands of kilometers across the Bay of Bengal. In the Eastern and Southern coastal belt of Sri Lanka, the floodwaters reached almost 1 km inland, causing unprecedented damage to infrastructure and over 4000 fatalities. Widespread destruction included several kilometres of rail tracks, dislocating …

A Vision System For Providing The Blind With 3d Colour Perception Of The Environment, S. Meers, Koren Ward Dec 2005

A Vision System For Providing The Blind With 3d Colour Perception Of The Environment, S. Meers, Koren Ward

Faculty of Informatics - Papers (Archive)

Although various attempts have been made at providing the blind with substitute visual perception, no existing method provides useful colour perception of the environment. This paper describes a substitute vision system which provides perception of the three-dimensional profile and colour of the surrounding environment via haptic sensations alone. This is aimed at allowing visually-impaired people to avoid obstacles and navigate the environment by recognising landmarks by their colour and profile. The prototype system uses stereo video cameras to capture colour images of the environment from which a disparity depth map can be calculated. The depth map is sampled into ten …

High-Capacity Steganography Using A Shared Colour Palette, G. Brisbane, R. Safavi-Naini, P. Ogunbona Dec 2005

High-Capacity Steganography Using A Shared Colour Palette, G. Brisbane, R. Safavi-Naini, P. Ogunbona

Faculty of Informatics - Papers (Archive)

Seppanen, Makela and Keskinarkaus (SMK) have proposed a high-capacity steganographic technique to conceal information within a colour image. The technique is significant because of the high volume of data that is embedded into pixels but it results in a high level of noise and so the quality of the resulting image is not acceptable. A new type of coding structure is proposed, which maintains a high capacity but lowers the level of noise. Secondly, an adaptive algorithm is used to identify pixel values that have a high capacity to distortion ratio. Also the maximum size of the coding structures is …

Access Policy Sheet For Access Control In Fine-Grained Xml, Jing Wu, Yi Mu, Jennifer Seberry, Chun Ruan Dec 2005

Access Policy Sheet For Access Control In Fine-Grained Xml, Jing Wu, Yi Mu, Jennifer Seberry, Chun Ruan

Faculty of Informatics - Papers (Archive)

We propose an access control scheme for developing authorization rules for XML documents, allowing flexible data granularity and authorization propagation. To simplify the complex access control policies in XML, we introduce a new tool: Authorization Policy Sheet (APS). Complex access control rules can be easily described in an APS. The administrator of a system can easily manage the access control of the system. With aid of Data Type Definitions(DTD), the policies given in an APS can be converted into a standard XML code that can be implemented in a normal XML environment.

Living With Trees – Perspectives From The Suburbs, Lesley M. Head, Pat Muir Dec 2005

Living With Trees – Perspectives From The Suburbs, Lesley M. Head, Pat Muir

Faculty of Science - Papers (Archive)

A study of suburban backyards and backyarders in Sydney and Wollongong revealed evidence of attitudes and behaviours in relation to trees. Attitudes are characterised under themes that indicate conditions of tolerance and belonging. They include attachment/risk, order/freedom and nativeness/alienness. While love is common, high levels of suspicion and intolerance towards trees in the suburban context are more common. Our findings confirm and throw further light on previous work indicating that many Australians have very partitioned views of the world in relationto where humans and nonhuman lifeforms belong. This partitioning must be understood in conceptual as well as spatial terms.

Service Discovery In Wireless Ad-Hoc Control Networks, Shengrong Bu, F. Naghdy Dec 2005

Service Discovery In Wireless Ad-Hoc Control Networks, Shengrong Bu, F. Naghdy

Faculty of Informatics - Papers (Archive)

A new concept in distributed control systems called Wireless Ad-hoc Control Networks (WACNets) is developed. WACNets is formed by a collection of nodes with the ability to sense, actuate and control. The network does not have a fixed structure, but evolves and self organises itself according to the control requirements of the system. The service discovery developed for WACNets is reported. A review of the existing Service Discovery Protocol (SDPs) including Jini, Salutation, Universal Plug and Play (UPnP), and Bluetooth technology is carried out. An overview of WACNets is provided. The service discovery protocol developed for WACNets is introduced and …

A Conceptual Model Of The Antecedents Of Behavioural Loyalty Of Dissatisfied Business Services Customers, Venkata Yanamandram, Lesley White Dec 2005

A Conceptual Model Of The Antecedents Of Behavioural Loyalty Of Dissatisfied Business Services Customers, Venkata Yanamandram, Lesley White

Faculty of Commerce - Papers (Archive)

This paper presents a conceptualisation of the factors that lead dissatisfied business-to-business (B2B) customers to stay with their existing service providers. While studies in a B2B context have addressed some important barriers to switching, they have not discussed all of these, and not necessarily under conditions of dissatisfaction. A literature review of previous research, both theoretical and empirical, identified that a gap in the body of knowledge exists regarding the reason that dissatisfied customers are behaviourally loyal, and results from a previous qualitative study unearthed additional barriers that exist. Hence, this paper proposes a model of the deterrents to switching …

Tourism Discretionary Spending Choice Behaviour, G. Crouch, Sara Dolnicar, T. Devinney, T. Huybers, J. Louviere, H. Oppewal Dec 2005

Tourism Discretionary Spending Choice Behaviour, G. Crouch, Sara Dolnicar, T. Devinney, T. Huybers, J. Louviere, H. Oppewal

Faculty of Commerce - Papers (Archive)

Studies of tourism demand are numerous. But studies of how consumers apportion discretionary resources to tourism and across other competing categories of discretionary expenditure are non-existent. Therefore, how individuals and households make trade-offs between, or assess the respective utilities of, the various categories of discretionary expenditure and allocate discretionary financial resources, appears to be unknown. This study seeks to address this need by examining discretionary expenditure through choice experiments. The data provide insights into how each type of discretionary expenditure is valued and how each type competes for a share of the discretionary expenditure ‘pie’. We discuss the results with …

Global Landscapes: A Speculative Assessment Of Emerging Organizational Structures Within The International Wine Industry, D. K. Aylward Dec 2005

Global Landscapes: A Speculative Assessment Of Emerging Organizational Structures Within The International Wine Industry, D. K. Aylward

Faculty of Commerce - Papers (Archive)

As a rapidly evolving sector the international wine industry represents an interesting subject for analysis. Over the past two centuries the industry has experienced a number of major innovations and direction changes. The organizational shifts involved in these changes have been profound. From a monopolization of wine culture through the 19th and much of the 20th century by Europeans, to the emergence of New World operators and their democratic influence, the international wine industry now stands at the edge of another major paradigm shift. This paper traces the industry’s historical changes and speculates on the implications of such issues as …

Seismic Lateral Response Of Piles In Liquefying Soil, D. S. Liyanapathirana, H. G. Poulos Dec 2005

Seismic Lateral Response Of Piles In Liquefying Soil, D. S. Liyanapathirana, H. G. Poulos

Faculty of Engineering - Papers (Archive)

Soil liquefaction is one of the major factors affecting the behavior of piles founded in seismically active areas. Although methods are available for seismic analysis of pile foundations, in many of them, the supporting soil is assumed to be an elastic material. Here a numerical model is presented which takes into account the reduction of soil stiffness and strength due to pore pressure generation and subsequent soil liquefaction, in addition to the material nonlinearity. Results obtained from the new method are compared with centrifuge test data and show excellent agreement with the observed pile behavior during these tests. To investigate …

A Digital Pixel Sensor Array With Programmable Dynamic Range, A. Kitchen, A. Bermak, Abdesselam Bouzerdoum Dec 2005

A Digital Pixel Sensor Array With Programmable Dynamic Range, A. Kitchen, A. Bermak, Abdesselam Bouzerdoum

Faculty of Informatics - Papers (Archive)

This paper presents a digital pixel sensor (DPS) array employing a time domain analogue-to-digital conversion (ADC) technique featuring adaptive dynamic range and programmable pixel response. The digital pixel comprises a photodiode, a voltage comparator, and an 8-bit static memory. The conversion characteristics of the ADC are determined by an array-based digital control circuit, which linearizes the pixel response, and sets the conversion range. The ADC response is adapted to different lighting conditions by setting a single clock frequency. Dynamic range compression was also experimentally demonstrated. This clearly shows the potential of the proposed technique in overcoming the limited dynamic range …

Fighting For Volunteers’ Time: Competition In The International Volunteering Industry, Sara Dolnicar, Melanie J. Randle Dec 2005

Fighting For Volunteers’ Time: Competition In The International Volunteering Industry, Sara Dolnicar, Melanie J. Randle

Faculty of Commerce - Papers (Archive)

Despite increased competitive pressures in the volunteering industry, the structure of competition within this non-profit sector has not been examined in the past. This study uses selected respondents from the 1999-2002 World Values Survey who have previously volunteered for multiple organisations. Based on the patterns of organisations that volunteers donated their time for, competition between volunteering organisations with different missions was analysed, resulting in five dimensions of volunteering missions within which volunteering organisations appear to be competing: altruistic, leisure, political, church, and other missions. The altruistic mission groups is the broadest and includes a wide variety of volunteering goals, whereas …

Scientists, Career Choices And Organisational Change: Managing Human Resources In Cross-Sector R&D Organisations, T. Turpin, Samuel Garrett-Jones, Kieren Diment Dec 2005

Scientists, Career Choices And Organisational Change: Managing Human Resources In Cross-Sector R&D Organisations, T. Turpin, Samuel Garrett-Jones, Kieren Diment

Faculty of Commerce - Papers (Archive)

The resource-based view of the firm has drawn attention to the role of human resources in building innovative capacity within firms. In 'high technology' firms, scientific capability is a critical factor in achieving international competitiveness. Science, however, is a costly business and many firms are entering into cross-sector R&D partnerships in order to gain access to leading edge scientific capability. The Australian Cooperative Research Centres (CRC) program is typical of the ways many governments are seeking to promote such cross-sector R&D collaboration. Scientists are key resources in these organisational arrangemation available about why and when scientists choose to work in …

Regioselective Synthesis Of Novel E-Edge-[60]Fullerenylmethanodihydropyrroles And 1,2-Dihydromethano[60]Fullerenes, Leila Chaker, Graham E. Ball, James R. Williams, Glenn A. Burley, Bill C. Hawkins, Paul A. Keller, Stephen G. Pyne Dec 2005

Regioselective Synthesis Of Novel E-Edge-[60]Fullerenylmethanodihydropyrroles And 1,2-Dihydromethano[60]Fullerenes, Leila Chaker, Graham E. Ball, James R. Williams, Glenn A. Burley, Bill C. Hawkins, Paul A. Keller, Stephen G. Pyne

Faculty of Science - Papers (Archive)

Treatment of a tethered N-(diphenylmethylene)glycinate-malonate derivative with [60]fullerene under Bingel conditions yielded an e-edge-[60]fullerenylmethanodihydropyrrole adduct in a regioselective manner. The regiochemical outcome was independent of the order of addition of either the N-(diphenylmethylene)glycinate or the malonate moieties. This new bis-adduct was also prepared in 13C enriched form allowing for its unequivocal structural characterization by 2D INADEQUATE NMR experiments. Ring-opening of the dihydropyrrole functionality of the bisadducts under reductive conditions gave exclusively novel dihydromethano[60]fullerene derivatives.

Culture As Concept And Influence In Environmental Research And Management, Lesley M. Head, D. Trigger, J. Mulcock Dec 2005

Culture As Concept And Influence In Environmental Research And Management, Lesley M. Head, D. Trigger, J. Mulcock

Faculty of Science - Papers (Archive)

Given that human activities have been implicated in the vast majority of contemporary environmental problems, it might be expected that research effort into those activities and the attitudes from which they stem would be both strongly supported by funding agencies, and of central interest to environmental scientists and land managers. In this paper we focus on an undervalued area of environmental humanities research—cultural analysis of the beliefs, practices and often unarticulated assumptions which underlie human–environmental relations. In discussing how cultural processes are central to environmental attitudes and behaviours, and how qualitative research methods can be used to understand them in …

The Australian Dollar’S Long-Term Fluctuations And Trend: The Commodity Prices-Cum-Economic Cycles Hypothesis, E. Sanidas Dec 2005

The Australian Dollar’S Long-Term Fluctuations And Trend: The Commodity Prices-Cum-Economic Cycles Hypothesis, E. Sanidas

Faculty of Business - Economics Working Papers

The Australian dollar’s exchange rate (mainly in relation to the American dollar) has received a considerable attention in research and several models have been proposed to explain its trend and fluctuations. Thus, as a conclusion of this research we can say that this commodity currency very much depends on the terms of trade which in turn depend on commodity prices. The present paper is based on this conclusion and hence proposes the possibility that the Australian dollar’s behavior is overwhelmingly explained by a handful of cycles of mainly harmonic frequencies. Using the principles of Fourier analysis, a simple regression provides …

Reviewing Workplace Bullying: Strengthening Approaches To A Complex Phenomenon, Diana J. Kelly Dec 2005

Reviewing Workplace Bullying: Strengthening Approaches To A Complex Phenomenon, Diana J. Kelly

Faculty of Arts - Papers (Archive)

Workplace bullying is a growing problem which is costly for organisations and individual targets. The costs for organisations include loss of productivity and increased insurance costs, as rising stress claims generate rises in premiums. Measuring the costs to individuals or the ethical capital of an organisation is much more difficult but just as important. This paper seeks to understand the research practices in bullying in order to identify potential needs for research and practice. After examining the nature and extent of workplace bullying, approaches to bullying are surveyed, revealing how different disciplines and professions investigate workplace bullying. The importance of …

Assessing The Impact Of The Workplace Relations Act From 1996 To 2004: Increasing Flexibility Or Decreasing Collectivism?, A. Hodgkinson, R. Markey Dec 2005

Assessing The Impact Of The Workplace Relations Act From 1996 To 2004: Increasing Flexibility Or Decreasing Collectivism?, A. Hodgkinson, R. Markey

Faculty of Business - Economics Working Papers

This paper tests the impact of the Workplace Relations Act 1996 (WRA) by looking at changes in the behaviour of a panel of workplaces in the Illawarra Region of NSW between 1996 and 2004. The results support the proposition that the major impact has been on the level of unionisation and union density in these workplaces. There was virtually no expansion in the use of enterprise bargaining or AWAs, although there was a small but significant increase in non-union agreement making. Rather than encourage the use of single jurisdictions to register awards and collective agreements, in the Illawarra at least, …
