Development Of A Novel Finder Pattern For Effective Color 2d-Barcode Detection, Hiroko Kato, Keng T. Tan, Douglas Chai

Research outputs pre 2011

With a camera mobile phone, which has become a "must-have" device, 2D-barcode works as an interface to bridge the physical and digital world. As the notion of ubiquitous computing has permeated, developing a new 2D-barcode and its applications has been a growing trend worldwide. A 2D-barcode symbol consists of two broad areas: data area and guide area. The components of the latter is collectively called "finder pattern" and used in locating the 2D-barcode symbol. The failure of finding the target symbol prevents a barcode reader from successfully decoding the barcode. Hence, designing a functional finder pattern is one of the …

The Use Of Border In Colour 2d Barcode, Siong Ong, Douglas Chai, Keng T. Tan

Research outputs pre 2011

In recent years, a trend has emerged in the use of colour to increase the data capacity of the 2D barcode. However the decoding of such colour barcode can be challenging in a mobile environment due to blurring effect that is commonly found in images captured by camera mobile phone. Blurring affects the synchronisation between the cells. It also causes the colour value of the cell to be wrongly interpreted. Hence, this paper proposes the use of border to improve the synchronisation and decoding. Three different types of border and the choice of its width will be investigated.

Magnetic Field Sensors And Visualizers Using Magnetic Photonic Crystals, Mikhail Vasiliev, Kamal Alameh, Viatcheslav Kotov

Research outputs pre 2011

Magneto-optical imaging is widely used to observe the domain patterns in magnetic materials, visualize defects in ferromagnetic objects, and measure the spatial distribution of stray magnetic fields. Optimized 1D magneto-photonic crystals enable a significant increase in the sensitivity of magneto-optical sensors. The properties of such devices based on the optimized reflection (doubled Faraday rotation) mode and the use of 1D magnetic photonic crystals as sensors are discussed. Experimental results of the fabrication and characterization of ferrite-garnet layers possessing uniaxial magnetic anisotropy are shown, and an optimized film structure suitable for magneto-optical imaging is proposed.

Photonic Nano-Structures For Water Quality Monitoring, Mikhail Vasiliev, Kamal Alameh

Research outputs pre 2011

We propose a new type of sensors suitable for water quality testing and for monitoring water contamination levels in domestic, industrial and environmental applications. The proposed sensing scheme uses Fourier transform cavity-enhanced absorption spectroscopy and novel compact sensing elements based on nanostructured photonic crystal-type optical coatings enabling the sensitive Fourier-domain processing methodology and maximising the absorption path length within the measurement system. The measurement scheme is shown to be suitable for the determination of small changes in the water absorption coefficients at a discrete set of wavelengths in the visible spectral region in response to small concentrations of pollutants with …

Novel Magnetic Photonic Crystal Structures For Magnetic Field Sensors And Visualizers, Mikhail Vasiliev, Viatcheslav A. Kotov, Kamal E. Alameh, Vladimir I. Belotelov, Anatoly K. Zvezdin

Research outputs pre 2011

Optimized one-dimensional (1-D) magnetophotonic crystals greatly increase the sensitivity of magnetooptical sensors, which are widely used in magnetooptical imaging to observe the magnetic domain patterns in magnetic materials, to observe the vortex states in superconductors, to detect small bits in magnetooptical recording media, to visualize defects in ferromagnetic objects, and to measure the value and spatial distribution of stray magnetic fields. This paper examines the properties of such devices operating in the optimized reflection (doubled Faraday rotation) mode and discusses the use of 1-D magnetophotonic crystals as sensors.

The effect of the width of inter-pixel double boundary trench isolation on the response resolution of a two dimensional CMOS compatible stacked gradient homojunction photodiode array was simulated. Insulation and P-doped double boundary trench isolation were compared. Both geometries showed improved crosstalk suppression and enhanced sensitivity compared to photodiode geometries previously investigated, combined with a reduction in fabrication complexity for the insulation DBTI configuration.

A Holistic Approach To Establishing An Effective Learning Environment For Psychology, Lynne Cohen, Paul Chang, Julie Ann Pooley, Lisbeth Pike

Research outputs pre 2011

The impetus for the Enhancing Quality and Learning (EQUAL) programme evolved out of concerns held by the staff in the School of Psychology at Edith Cowan University (ECU) regarding the difficulties encountered by first year psychology students and the subsequent low retention rate of these students in the psychology course. The EQUAL programme focused on easing the transition of high school students into university studies by enhancing the social support networks of commencing students. The programme was designed to be an holistic approach to enhancing a sense of belonging to the School of Psychology and comprised seven components. These are …

Microstructured Arrayed Microfluidic Waveguide Structure For Infrared Radiation Focusing And Transfer, Paul B. Laursen, Kamal Alameh, Mikhail Vasiliev, Nicholas C. Elliott

Research outputs pre 2011

A microstructured arrayed microfluidic waveguide structure for infrared radiation focussing and transfer is proposed and demonstrated. The arrayed waveguide structure comprises Masterbond UV-curable epoxy UV15 optimised using ZEMAX optical design software to achieve high efficiency of heat capture through far-infrared light focussing and subsequent absorption of the radiation on a centralised fluid medium. A high degree of alignment of the precision-positioned fluidic microchannels with the symmetry axes and the focal plane locations of the cylindrical microlens array is demonstrated, which maximises the efficiency of absorption of the incident IR light energy within the moving fluid. Observation of ink flows through …

"We Are Next!": Listening To Jewish Voices In A Multicultural Country, Lelia Rosalind Green, Gerry Bloustien, Mark Balnaves

Research outputs pre 2011

If the notion of being at home in one’s country is safe and reassuring, the homeland and the heartland of what we judge important, then the thought that a countryneeds its own homeland security is destined to create a sense of unease. Australia’s homeland security unit was set up in May 2003 (Riley), just weeks after theallies’ Coalition of the Willing had celebrated George W Bush’s declaration aboard the USS Abraham Lincoln, of ‘Victory in Iraq’ (BBC). It might have been expected, inthis victorious glow, that the country would feel confidently able to return to a state of security. Apparently …

Creating Preservation-Ready Web Resources, Joan A. Smith, Michael L. Nelson

Computer Science Faculty Publications

There are innumerable departmental, community, and personal web sites worthy of long-term preservation but proportionally fewer archivists available to properly prepare and process such sites. We propose a simple model for such everyday web sites which takes advantage of the web server itself to help prepare the site's resources for preservation. This is accomplished by having metadata utilities analyze the resource at the time of dissemination. The web server responds to the archiving repository crawler by sending both the resource and the just-in-time generated metadata as a straight-forward XML-formatted response. We call this complex object (resource + metadata) a CRATE. …

Emergent Behavior In Massively-Deployed Sensor Networks, Ekaterina Shurkova, Ruzana Ishak, Stephan Olariu, Shaharuddin Salleh

Computer Science Faculty Publications

The phenomenal advances in MEMS and nanotechnology make it feasible to build small devices, referred to as sensors that are able to sense, compute and communicate over small distances. The massive deployment of these small devices raises the fascinating question of whether or not the sensors, as a collectivity, will display emergent behavior, just as living organisms do. In this work we report on a recent effort intended to observe emerging behavior of large groups of sensor nodes, like living cells demonstrate. Imagine a massive deployment of sensors that can be in two states "red" and "blue". At deployment time …

Efficient Corona Training Protocols For Sensor Networks, Alan A. Bertossi, Stephan Olariu, Cristina M. Pinotti

Computer Science Faculty Publications

Phenomenal advances in nano-technology and packaging have made it possible to develop miniaturized low-power devices that integrate sensing, special-purpose computing, and wireless communications capabilities. It is expected that these small devices, referred to as sensors, will be mass-produced and deployed, making their production cost negligible. Due to their small form factor and modest non-renewable energy budget, individual sensors are not expected to be GPS-enabled. Moreover, in most applications, exact geographic location is not necessary, and all that the individual sensors need is a coarse-grain location awareness. The task of acquiring such a coarse-grain location awareness is referred to as training. …

An Intelligent Model To Control Preemption Rate Of Instantaneous Request Calls In Networks With Book-Ahead Reservation, Iftekhar Ahmad, Joarder Kamruzzaman, Daryoush Habibi, Farzana Islam

Research outputs pre 2011

Resource sharing between book-ahead (BA) and instantaneous request (IR) reservation often results in high preemption rate of on-going IR calls. High IR call preemption rate causes interruption to service continuity which is considered as detrimental in a QoS-enabled network. A number of call admission control models have been proposed in literature to reduce the preemption rate of on-going IR calls. Many of these models use a tuning parameter to achieve certain level of preemption rate. This paper presents an artificial neural network (ANN) model to dynamically control the preemption rate of on-going calls in a QoS-enabled network. The model maps …

Cultural Factors Affecting Smoking Intentions In Sri Lankan Immigrant Adolescents: An Exploratory Study, Raguragavan Ganeshasundaram, Nadine Henley

Research outputs pre 2011

This paper reports a small exploratory investigation into smoking intentions amongst Sri Lankan immigrant adolescents living in Perth, Western Australia. Four focus group discussions were conducted to explore how cultural values are expressed in this group's beliefs and attitudes towards smoking and non-smoking and how these values may influence their smoking-related behaviour. Females and males attached similar negative values to smoking per se. However, generally, males saw peers' smoking as a way to be cool and popular while females saw peers' smoking as a way to solve stress and other personal problems. Males had strong positive associations with their favourite …

Bankruptcy's Rarity: An Essay On Small Business Bankruptcy In The United States, Edward R. Morrison

Faculty Scholarship

Most nations have enacted statutes governing business liquidation and reorganization. These statutes are the primary focus when policymakers and scholars discuss ways to improve laws governing business failure. This focus is misplaced, at least for distressed small businesses in the United States.

Evidence from a major credit bureau shows that over eighty percent of these businesses liquidate or reorganize without invoking the formal Bankruptcy Code.

The businesses instead invoke procedures derived from the laws of contracts, secured lending, and trusts. These procedures can be cheaper and speedier than a formal bankruptcy filing, but they typically require unanimous consent of senior, …

The Perils Of Theory, Peter L. Strauss

Faculty Scholarship

As I recall, Professor Clark had more sense than to be my student at Columbia, but I heard a lot about him from admiring colleagues. Clearly he has fulfilled the promise they saw, and this remarkable Symposium is only one indicator of that. The article to which our attention is properly drawn, more than two and a quarter centuries into our nation's history, has an originalist base, tightly and persuasively focused on original understandings of the Supremacy Clause. Professor Clark lays out a cogent account of the Clause's politics and the centrality of its language to the most fundamental of …

Sovereign Wealth Funds And Corporate Governance: A Minimalist Response To The New Mercantilism, Ronald J. Gilson, Curtis J. Milhaupt

Faculty Scholarship

Keynes taught years ago that international cash flows are always political. Western response to the enormous increase in the number and the assets of sovereign wealth funds (SWFs), and other government-directed investment vehicles that often get lumped together under the SWF label, proves Keynes right. To their most severe critics, SWFs are a threat to the sovereignty of the nations in whose corporations they invest. The heat of the metaphors matches the volume of the complaints. The nations whose corporations are targets of investments are said to be threatened with becoming "sharecropper" states if ownership of industry moves to foreign-government …

Lobbying And Campaign Finance: Separate And Together, Richard Briffault

Faculty Scholarship

The relationship between lobbying and campaign finance is complex, contested, and changing. Lobbying and campaign finance are two important forms of political activity that combine money and communication in ways that have significant implications for democratic self-government. The two practices frequently interact and reinforce each other, with individuals, organizations, and interest groups deploying both lobbyists and campaign money to advance their goals. Congress, in 2007, for the first time explicitly recognized the intersection of campaign finance and lobbying when it adopted legislation specifically regulating the campaign finance activities of lobbyists. At roughly the same time, several of the leading candidates …

Getting Beyond The Crossfire Phenomenon: A Militant Moderate's Take On The Role Of Foreign Authority In Constitutional Interpretation, Melissa A. Waters

Scholarship@WashULaw

This brief essay sketches out a, "militant moderate," take on the role of foreign and international law in constitutional interpretation. The essay examines and critiques the key arguments and assumptions of both internationalists (like Justice Breyer) and nationalists (like Justice Scalia). It urges scholars and policymakers to shift from the Crossfire-style debate that has dominated in recent years, toward a more nuanced approach that strikes a balance between the legitimate concerns of nationalists and the legitimate aspirations of internationalists. A militant moderate approach situates the debate over foreign authority in its broader context: American judges' growing participation in transnational judicial …
