Multi-Wavelength Laser Sensor For Intruder Detection And Discrimination, Kavitha Venkataraayan, Sreten Askraba, Kamal E. Alameh, Clifton L. Smith
Research outputs 2011
An intruder detection and discrimination sensor with improved optical design is developed using lasers of different wavelengths to demonstrate the concept of discrimination over a distance of 6 m. A distinctive feature of optics is used to provide additional transverse laser beam scanning. The sample objects used to demonstrate the concept of discrimination over a distance of 6 m are leaf, bark, black fabric, PVC, wood and camouflage material. A camouflage material is chosen to illustrate the discrimination capability of the sensor. The sensor utilizes a five-wavelength laser combination module, which sequentially emits identically-polarized laser light beams along one optical …
Multi Camera Visual Saliency Using Image Stitching, Christopher Wing Hong Ngau, Li-Minn Ang, Kah Phooi Seng
Multi Camera Visual Saliency Using Image Stitching, Christopher Wing Hong Ngau, Li-Minn Ang, Kah Phooi Seng
Research outputs 2011
This paper presents and investigates two models for a multi camera configuration with visual saliency capability. Applications in various imaging fields each have a different set of detection parameters and requirements which would result in the necessity of software changes. The visual saliency capability offered by this multi camera model allows generic detection of conspicuous objects be it human or nonhuman based on simple low level features. As multiple cameras are used, an image stitching technique is employed to allow combination of Field-of-View (FoV) from different camera captures to provide a panoramic detection field. The stitching technique is also used …

Teaching Software Engineering Project Management-A Novel Approach For Software Engineering Programs, Craig Caulfield, David Veal, Stanislaw Maj
Research outputs 2011
In response to real and perceived short-comings in the quality and productivity of software engineering practices and projects, professionally-endorsed graduate and post-graduate curriculum guides have been developed to meet technical developments and evolving industry demands. Each of these curriculum guidelines identifies better software project management skills as critical for all graduating students, but they provide little guidance on how to achieve this. One possible way is to use a serious game - a game designed to teach and educate players about some of the dynamic complexities of the field in a safe and inexpensive environment. This paper presents the results …

Inoculations With Arbuscular Mycorrhizal Fungi Increase Vegetable Yields And Decrease Phoxim Concentrations In Carrot And Green Onion And Their Soils, Fa Yuan Wang, Rui Jian Tong, Zhao Yong Shi, Xiao Feng Xu, Xinhua He
Research outputs 2011
Background As one of the most widely used organophosphate insecticides in vegetable production, phoxim (C12H15N2O3PS) is often found as residues in crops and soils and thus poses a potential threat to public health and environment. Arbuscular mycorrhizal (AM) fungi may make a contribution to the decrease of organophosphate residues in crops and/or the degradation in soils, but such effects remain unknown. Methodology/Principal Findings A greenhouse pot experiment studied the influence of AM fungi and phoxim application on the growth of carrot and green onion, and phoxim concentrations in the two vegetables and their soil media. Treatments included three AM fungal …
Gradients In The Number Of Species At Reef-Seagrass Ecotones Explained By Gradients In Abundance, Fernando Tuya, Mathew Vanderklift, Thomas Wernberg, Mads Thomsen
Gradients In The Number Of Species At Reef-Seagrass Ecotones Explained By Gradients In Abundance, Fernando Tuya, Mathew Vanderklift, Thomas Wernberg, Mads Thomsen
Research outputs 2011
Gradients in the composition and diversity (e. g. number of species) of faunal assemblages are common at ecotones between juxtaposed habitats. Patterns in the number of species, however, can be confounded by patterns in abundance of individuals, because more species tend to be found wherever there are more individuals. We tested whether proximity to reefs influenced patterns in the composition and diversity ('species density' = number of species per area and 'species richness' = number of species per number of individuals) of prosobranch gastropods in meadows of two seagrasses with different physiognomy: Posidonia and Amphibolis. A change in the species …

Reinforcement Learning Of Competitive And Cooperative Skills In Soccer Agents, Jinsong Leng, Chee Lim
Research outputs 2011
The main aim of this paper is to provide a comprehensive numerical analysis on the efficiency of various reinforcementlearning (RL) techniques in an agent-based soccer game. The SoccerBots is employed as a simulation testbed to analyze the effectiveness of RL techniques under various scenarios. A hybrid agent teaming framework for investigating agent team architecture, learning abilities, and other specific behaviours is presented. Novel RL algorithms to verify the competitiveandcooperativelearning abilities of goal-oriented agents for decision-making are developed. In particular, the tile coding (TC) technique, a function approximation approach, is used to prevent the state space from growing exponentially, hence avoiding …

A New Seal Verification For Chinese Color Seal, Zhihu Huang, Jinsong Leng
Research outputs 2011
Automatic seal imprint identification system is highly demanded in oriental countries. Even though several seal identification techniques have been proposed, it is seldom to find the papers on the recovery of lost seal imprint strokes caused by superimposition. In this paper, a new seal verification for Chinese color seal is proposed. This approach segments the seal imprint from the input image in terms of the adaptive thresholds. The lost seal imprint strokes are recovered based on the text stroke width that can be detected automatically. In addition, the moment-based seal verification is to compare the reference seal imprint and the …

The Relationship Between Water, Health And Global Environmental Change, As Interpreted Through Five Key Multilateral Environmental Agreements (Meas), Pierre Horwitz, Lucilla Spini, Kathryn Campbell, R J Thomas, Jo Mulongoy
Research outputs 2011
For five Multilateral Environmental Agreements (MEAs), we have examined the way the relationship between water, health and global environmental change is expressed and how it has evolved recently. We recognize a distinction between an emphasis on water and reservoirs of water for health (for drinking water supplies, sanitation and hygiene), and a focus on places of water, where wetland ecosystems provide a service for human well-being which encompasses health. We also recognize a trend over time for the MEAs to increasingly address water, health and global change issues as a reaction to emerging infectious diseases and global pandemics. For both …

Limiting Factors For Crayfish And Finfish In Acidic Coal Pit Lake, Clinton Mccullough, Mark Lund
Research outputs 2011
World-wide, open-cut mining operations often leave pit lakes at closure. The Collie Lake District in south-west Australia has 13 pit lakes from open-cut coal extraction, with more expected. Many lakes may offer beneficial end uses as fisheries habitat for biodiversity or for recreational species. However, pit lakes may have degraded water quality due to Acid and Metalliferous Drainage (AMD). A literature review and survey for marron (endemic crayfish of biodiversity and recreational value) and fin-fish (of only biodiversity value) found that crayfish were likely more limited by habitat and food availability, and fin-fish by water quality. Management of these mild …

Research outputs 2011
Bi-substituted iron garnet (Bi:IG) compounds synthesized in thin film form are the best semi-transparent magneto-optical (MO) materials for applications in magnetic recording, optical sensors, and photonics. These materials can possess attractive magnetic properties and the highest specific Faraday rotation in the visible and near-infrared spectral regions, if the deposited layers contain a high volumetric fraction of the garnet phase and possess high-quality surfaces and microstructure. In this paper, we study the effects of various deposition and annealing process parameters on the properties of Bi:IG and garnet-oxide nanocomposite films of several composition types fabricated using radio-frequency (RF) sputtering deposition followed by …

A Preliminary Introduction To The Otam: Exploring Users’ Perceptions Of Their On-Going Interaction With Adopted Technologies, Shirlee-Ann Knight, Janice M. Burn
Research outputs 2011
A common criticism directed at Davis’ (1986; 1989) Technology Acceptance Model relates to its failure to adequately frame the “experienced” user’s ongoing adoption and exploitation of information technologies. Given the pervasive nature of technology into individual users’ ongoing, everyday communication and information interactions, along with the “new adopter” becoming an increasingly rare entity, the TAM is in danger of becoming a somewhat obsolete framework for investigating user-technology interaction. Presented is a critical analysis of the development and current state of the TAM, followed by a proposed addition to the existing Perceived Usefulness (PU) and Perceived Ease of Use (PEoU) TAM …

In 2007, it was shown that the shipping of lead (Pb) through Esperance Port in Western Australia resulted in contamination and increased Pb concentrations in children. A clean-up strategy was implemented; however, little attention was given to other metals. In consultation with the community, a cross-sectional exposure study was designed. Thirty-nine children aged 1 to 12 years provided samples of hair, urine, drinking water, residential soil and dust. Concentrations of nickel (Ni) and Pb were low in biological and environmental samples. Hair aluminium (Al) (lower than the detection limit [DL] to 251 μg/g) and copper (Cu) (7 to 415 μg/g), …

Analysis Of Data Remaining On Second Hand Adsl Routers, Patryk Szewczyk
Research outputs 2011
In theory, an ADSL router can provide an additional layer of security to a wired and wireless network through; access control, wireless encryption, firewall rule sets, and network event logging. An ADSL router may also contain the users’ usage habits and broadband account credentials. However, end-users may be unaware of the intricacies of the security measures available and the potentially confidential information stored on their device. As a result a second hand ADSL router may contain a wealth of user-specific information if not wiped and disposed of in a secure manner. This paper shows the data that was acquired from …

Subtidal Macroalgal Richness, Diversity And Turnover, At Multiple Spatial Scales, Along The Southwestern Australian Coastline, David Smale, G Kendrick, Thomas Wernberg
Research outputs 2011
Patterns of species richness are governed by processes that act at vastly different spatial scales. In the marine system of southwest Australia, macroalgal assemblage structure and richness is thought to be strongly influenced by both the Leeuwin Current, which acts at large regional spatial scales, and small-scale processes such as competition, wave disturbance and habitat heterogeneity. We examined macroalgal species richness and diversity at multiple spatial scales using a three-factor hierarchal design. Spatial extents ranged from metres (between quadrats) to many hundreds of kilometres (between regions), and the study encompassed almost 2000 km of temperate coastline. Macroalgal assemblages were highly …

Spatially Resolved Inhomogeneous Depressions Of The Excitons Zeeman Splitting In An Integrated Magnetic-Multiple Quantum Wells System, Ahmed Abdelrahman, Hoon Soo Kang, Sang Youp Yim, Mikhail Vasiliev, Kamal Alameh, Yong Lee
Research outputs 2011
We report on the generation of a nonuniform spatial distribution of the heavy and light-hole excitons in a multiple quantum wells system integrated with a localized inhomogeneous weak magnetic field. An inhomogeneous spatially resolved depression of the Zeeman splittings of the heavy-hole excitons and the light-hole excitons with respect to their translational wave vectors is observed. A localized inverted concentration of the two types of the excitons due to the inhomogeneity of the magnetic field is also measured. A simple method to integrate permanent magnetic materials with the multiple quantum wells system is used to create an accessible degree of …
The Combined Conceptual Life Cycle Model Of Information Quality In User Perceptions Of Iq On The Web, Shirlee-Ann Knight
The Combined Conceptual Life Cycle Model Of Information Quality In User Perceptions Of Iq On The Web, Shirlee-Ann Knight
Research outputs 2011
Presented is the Combined Conceptual Life Cycle (CCLC) Model of Information Quality (IQ). The CCLC conceptualises information/data quality as being a highly relative construct, best understood in terms of sixteen IQ dimensions housed within four broad IQ categories: namely; Intrinsic IQ, Representational IQ, Interactional IQ, and Contextual IQ. The four categories themselves are seen as falling into two information life cycle contexts: that of (1) data/information generation and (2) data/information use. By conceptualising user perceptions of IQ in terms of the information life cycle, the model is able to demonstrate where in the information life cycle users are most likely …

Contemporary impacts of anthropogenic climate change on ecosystems are increasingly being recognized. Documenting the extent of these impacts requires quantitative tools for analyses of ecological observations to distinguish climate impacts in noisy data and to understand interactions between climate variability and other drivers of change. To assist the development of reliable statistical approaches, we review the marine climate change literature and provide suggestions for quantitative approaches in climate change ecology. We compiled 267 peer-reviewed articles that examined relationships between climate change and marine ecological variables. Of the articles with time series data (n = 186), 75% used statistics to test …

Resilience Of Phreatophytic Vegetation To Groundwater Drawdown: Is Recovery Possible Under A Drying Climate?, Bea Sommer, Raymond Froend
Resilience Of Phreatophytic Vegetation To Groundwater Drawdown: Is Recovery Possible Under A Drying Climate?, Bea Sommer, Raymond Froend
Research outputs 2011
Banksia (Proteaceae) woodlands are one of a number of groundwater-dependent ecosystems in southwestern Western Australia that are threatened by groundwater abstraction. In addition to this threat is an ongoing decline in regional water tables due to a drying climate. We used ecological resilience theory to analyse and interpret a long-term vegetation monitoring dataset from a site that has experienced an abstraction-induced acute groundwater drawdown in the late 1980s and early 1990s. Despite reduced plant abundance, all dominant over- and understorey species were still found on all transect plots in which they were recorded pre-drawdown. This suggests a notional resilience and …

Recovery From The Impact Of Light Reduction On The Seagrass Amphibolis Griffithii, Insights For Dredging Management, Kathryn Mcmahon, Paul Lavery, Michael Mulligan
Research outputs 2011
A large-scale, manipulative experiment was conducted to examine the extent and rate of recovery of meadows of the temperate Australian seagrass, Amphibolis griffithii to different light-reduction scenarios typical of dredging operations, and to identify potential indicators of recovery from light reduction stress. Shade cloth was used to mimic different intensities, durations and start times of light reduction, and then was removed to assess the recovery. The meadow could recover from 3 months of light stress (5–18% ambient) following 10 months re-exposure to ambient light, even when up to 72% of leaf biomass was lost, much faster recovery rates than has …

Lake Kepwari is a rehabilitated lake in the Collie Basin lignite mining area in Western Australia. The water quality of Lake Kepwari was modeled with the pit lake hydrodynamic and water quality model PITLAKQ. Based on a hydrodynamically validated model, water quality scenarios were used to quantify the sensitivity of different acidity sources including groundwater exchange, surface runoff and erosion, providing new insights into the system. The technique of monthly aggregation of all sources and sinks of acidity, based on detailed model output, provided the basis for useful conclusions. Model results suggest a new focus of field investigations to improve …

Evaluating The Factors Limiting Algal Biomass In Acidic Pit Lakes Of The Collie Lake District, Western Australia, Naresh Radhakrishnan, Clinton Mccullough, Mark Lund, Santiago Larranaga Arrizabalaga
Research outputs 2011
Acidic pit lakes often have elevated metal concentrations, very low nutrient concentrations and very low algal primary productivity. A microcosm experiment was performed to identify the main limiting factor(s) for algal biomass. Nutrients (N, P and C) were added in all possible combinations to pit lake water in the presence or absence of pit lake sediment. Microcosms without sediment showed higher chlorophyll a concentrations compared to the treatments with sediment. Microcosms where nitrogen and phosphorus were added showed highest chlorophyll a concentrations. Results suggest that algal biomass in pit lakes may be primarily limited by low nitrogen and phosphorus concentrations.

In objective-based data farming, decision variables of the Red Team are evolved using evolutionary algorithms such that a series of rigorous Red Team strategies can be generated to assess the Blue Team's operational tactics. Typically, less than 10 decision variables (out of 1000+) are selected by subject matter experts (SMEs) based on their past experience and intuition. While this approach can significantly improve the computing efficiency of the data farming process, it limits the chance of discovering “surprises” and moreover, data farming may be used only to verify SMEs' assumptions. A straightforward solution is simply to evolve all Red Team …

IRC•37-2001, the Indian Roads Congress standard deals with the design of flexible pavements and recommends the California Bearing Ratio (CBR) as an indicator of subgrade soil strength. The subbase/base thickness of pavement is governed by the CBR value of the subgrade soil along with some other parameters such as traffic intensity, climatic conditions, etc. The conventional CBR testing method is expensive, time consuming and its repeatability is low. Additionally, it is very difficult to mould the sample at the desired in-situ density in the laboratory CBR test. Values of in• situ density are underestimated due to local dampness of surface …

Mine void pit lakes often contain water of poor quality with potential for environmental harm that may dwarf other mine closure environmental issues in terms of severity, scope, and longevity. This is particularly so when many pit lakes occur close together and thus form a new ‘‘lake district’’ landscape. Pit lakes that can be developed into healthy lake or wetland ecosystems as a beneficial end use provide opportunities for the mining industry to fulfil commitments to sustainability. Clearly articulated restoration goals and a strategic closure plan are necessary to ensure pit lake restoration toward a new, yet regionally-relevant, aquatic ecosystem, …

A Low Cost Adaptive Graphical User Interface For The Visually Handicapped With Multiple Conditions, David Veal, Stanislaw Maj
Research outputs 2011
Limited trials have been demonstrated that a Graphical User Interface (GUI) for the visually handicapped called Dynamic Pattern System (DPS) can adaptively utilize residual vision by generating different patterns, colors and shapes. Low vision simulators, used by normally sighted, have allowed researchers to clearly identify visual impairments that can be helped by DPS. However, it is not uncommon for the visually handicapped to suffer from multiple conditions having a multiplicative degenerative effect on their sight. This paper demonstrates how DPS can be used to assist individuals with compound sight disorders.
