Large Object Segmentation With Region Priority Rendering, Yang-Wai Chow, Ronald Pose, Matthew Regan Jan 2005

Large Object Segmentation With Region Priority Rendering, Yang-Wai Chow, Ronald Pose, Matthew Regan

Faculty of Informatics - Papers (Archive)

The Address Recalculation Pipeline is a hardware architecture designed to reduce the end-to-end latency suffered by immersive Head Mounted Display virtual reality systems. A demand driven rendering technique known as priority rendering was devised for use in conjunction with the address recalculation pipeline. Using this technique, different sections of a scene can be updated at different rates, resulting in reductions to the rendering load.Further reductions can potentially be achieved by allowing for the segmenting of large objects. However in doing so a tearing problem surfaces, which has to be overcome before large object segmentation can be used effectively in priority …

The Analysis Of Crop Cultivar Breeding And Evaluation Trials: An Overview Of Current Mixed Model Approaches, A B. Smith, Brian R. Cullis, R Thompson Jan 2005

The Analysis Of Crop Cultivar Breeding And Evaluation Trials: An Overview Of Current Mixed Model Approaches, A B. Smith, Brian R. Cullis, R Thompson

Faculty of Informatics - Papers (Archive)

The analysis of series of crop variety trials has a long history with the earliest approaches being based on ANOVA methods. Kempton (1984) discussed the inadequacies of this approach, summarized the alternatives available at that time and noted that all of these approaches could be classified as multiplicative models. Recently, mixed model approaches have become popular for the analysis of series of variety trials. There are numerous reasons for their use, including the ease with which incomplete data (not all varieties in all trials) can be handled and the ability to appropriately model within-trial error variation. Currently, the most common …

Dice: Internet Delivery Of Immersive Voice Communication For Crowded Virtual Spaces, P. Boustead, Farzad Safaei, M. Dowlatshahi Jan 2005

Dice: Internet Delivery Of Immersive Voice Communication For Crowded Virtual Spaces, P. Boustead, Farzad Safaei, M. Dowlatshahi

Faculty of Informatics - Papers (Archive)

This paper develops a scalable system design for the creation, and delivery over the Internet, of a realistic voice communication service for crowded virtual spaces. Examples of crowded spaces include virtual market places or battlefields in online games. A realistic crowded audio scene including spatial rendering of the voices of surrounding avatars is impractical to deliver over the Internet in a peer-to-peer manner due to access bandwidth limitations and cost. A brute force server model, on the other hand, will face significant computational costs and scalability issues. This paper presents a novel server-based architecture for this service that performs simple …

Sketch-Based Image Matching Using Angular Partitioning, A. Chalechale, G. Naghdy, Alfred Mertins Jan 2005

Sketch-Based Image Matching Using Angular Partitioning, A. Chalechale, G. Naghdy, Alfred Mertins

Faculty of Informatics - Papers (Archive)

This work presents a novel method for image similarity measure, where a hand-drawn rough black and white sketch is compared with an existing data base of full color images (art works and photographs). The proposed system creates ambient intelligence in terms of the evaluation of nonprecise, easy to input sketched information. The system can then provide the user with options of either retrieving similar images in the database or ranking the quality of the sketch against a given standard, i.e., the original image model. Alternatively, the inherent pattern-matching capability of the system can be utilized to allow detection of distortion …

Latency-Driven Distribution: Infrastructure Needs Of Participatory Entertainment Applications, Farzad Safaei, P. Boustead, C. D. Nguyen, J. Brun, M. Dowlatshahi Jan 2005

Latency-Driven Distribution: Infrastructure Needs Of Participatory Entertainment Applications, Farzad Safaei, P. Boustead, C. D. Nguyen, J. Brun, M. Dowlatshahi

Faculty of Informatics - Papers (Archive)

This article evaluates network and server infrastructure requirements to support real-time flows associated with networked entertainment applications. These include the state information flow to update the status of the virtual environment and immersive communication flows such as voice, video, gesture, and haptics communication. The article demonstrates that scaling these applications to large geographical spreads of participants requires distribution of computation to meet the latency constraints of the applications. This latency-driven distribution of computation is essential even when there are no limitations on the availability of computational resources in one location. The article provides detailed results on distributed server architectures for …

Dynamic Resource Adaptation In A Heterogeneous Peer-To-Peer Environment, Letian Rong, I. Burnett Jan 2005

Dynamic Resource Adaptation In A Heterogeneous Peer-To-Peer Environment, Letian Rong, I. Burnett

Faculty of Informatics - Papers (Archive)

This paper focuses on metadata-based, multimedia resource representation and retrieval in a P2P environment as a means of universal multimedia access (UMA). The primary focus of the work is a P2P architecture, which uses MPEG-21 as standards based technique to dynamically adapt resources to various usage environments. In the architecture, a super peer based approach is used to cluster peers, store peer information, perform searches and instruct peers to adapt/send resources. Also a two-stages based adaptation method is introduced to adapt search results and resources in an intelligent manner based on the usage environment attributes. The concept is demonstrated using …

Novel Architecture For Surveillance Cameras With Complementary Metal Oxide Semiconductor Image Sensors, Igor Kharitonenko, Wanqing Li, Chaminda Weerasinghe Jan 2005

Novel Architecture For Surveillance Cameras With Complementary Metal Oxide Semiconductor Image Sensors, Igor Kharitonenko, Wanqing Li, Chaminda Weerasinghe

Faculty of Informatics - Papers (Archive)

This work presents a novel architecture of an intelligent video surveillance camera. It is embedded with automated scene analysis and object behavior detection, so that operators can monitor more venues relying on the system that provides immediate response to suspicious events. The developed camera turns passive video data recording systems into active collaborators with security operators leaving to them only high-level decision making, while automatically carrying out all monotonous work on continuous video monitoring. When there is no alarming activity inside a restricted area the camera automatically turns back to the whole view mode.

Skin Segmentation Using Color Pixel Classification: Analysis And Comparison, Son Lam Phung, A. Bouzerdoum, D. Chai Jan 2005

Skin Segmentation Using Color Pixel Classification: Analysis And Comparison, Son Lam Phung, A. Bouzerdoum, D. Chai

Faculty of Informatics - Papers (Archive)

This work presents a study of three important issues of the color pixel classification approach to skin segmentation: color representation, color quantization, and classification algorithm. Our analysis of several representative color spaces using the Bayesian classifier with the histogram technique shows that skin segmentation based on color pixel classification is largely unaffected by the choice of the color space. However, segmentation performance degrades when only chrominance channels are used in classification. Furthermore, we find that color quantization can be as low as 64 bins per channel, although higher histogram sizes give better segmentation performance. The Bayesian classifier with the histogram …

A New Method For Constructing T-Matrices, M. Xia, Tianbing Xia, Jennifer Seberry, G. Zuo Jan 2005

A New Method For Constructing T-Matrices, M. Xia, Tianbing Xia, Jennifer Seberry, G. Zuo

Faculty of Informatics - Papers (Archive)

For every prime power q = 3 (mod 8) we prove the existence of (q; x, 0, y, y)-partitions of GF(q) with q = x2 + 2y2 for some x, y, which are very useful for constructing SDS, T-matrices and Hadamard matrices. We discuss the transformations of (q; x, 0, y, y)-partitions and, by using the partitions, construct generalized cyclotomic classes which have properties similar to those of classical cyclotomic classes. Thus we provide a new construction for T-matrices of order q2.

The Need For A Digital Aid Framework In Humanitarian Relief, J. Sargent, Katina Michael Jan 2005

The Need For A Digital Aid Framework In Humanitarian Relief, J. Sargent, Katina Michael

Faculty of Informatics - Papers (Archive)

Humanitarian relief organizations are increasingly becoming reliant upon the use of Information Technology & Telecommunications (IT&T) for the distribution of aid to refugees and Internally Displaced Persons (IDP) throughout the world. Traditionally, basic telecommunications infrastructure like the public switch telephone network (PSTN) has been used to transmit important information but today humanitarian relief organizations are attempting to utilize emerging technologies such as global positioning systems (GPS) telephones and geographic information systems (GIS). For the greater part IT&T utilization by relief organizations has happened in an ad-hoc manner in response to specific events. This paper proposes the use of a complete …

Applications Of Human Transponder Implants In Mobile Commerce, Katina Michael, Amelia Masters Jan 2005

Applications Of Human Transponder Implants In Mobile Commerce, Katina Michael, Amelia Masters

Faculty of Informatics - Papers (Archive)

When the ENIAC was launched in 1946, no one could ever have imagined that the giant thinking machine would one day find itself inside the anthropos. However the continuing quest for miniaturisation has made this possible: from luggables to wearables, and now, ultimately to implantable devices. This paper explores the potential for RFID transponder implants in humans for emerging mobile commerce applications. Three usability contexts have been defined to explore the applications which are projected to become mainstream service offerings. This paper is significant because it dispels the common misconception that microchip implants for humans are still some time away. …

A New Divide And Conquer Algorithm For Graph-Based Image And Video Segmentation, Wanqing Li, M. Shi, P. Ogunbona Jan 2005

A New Divide And Conquer Algorithm For Graph-Based Image And Video Segmentation, Wanqing Li, M. Shi, P. Ogunbona

Faculty of Informatics - Papers (Archive)

The concept of the Shortest (or Minimum) Spanning Tree (SST)and Recursive SST (RSST) of an undirected weighted graph has been successfully applied in image segmentation and edge detection. This paper presents a divide-and-conquer approach for (R)SST based image segmentation in order to over-come the problem of high computational complexity associated with conventional graph algorithms. In the simplest form, the proposed approach, block-based RSST (BRSST), first divides the image into rectangular blocks, finds the (R)SST of each block individually using conventional graph algorithms and, then, merges the (R) SSTs of all image blocks to form an (R)SST of the entire image. …

Latency And Scalability: A Survey Of Issues And Techniques For Supporting Networked Games, Xinbo Jiang, Farzad Safaei, P. Boustead Jan 2005

Latency And Scalability: A Survey Of Issues And Techniques For Supporting Networked Games, Xinbo Jiang, Farzad Safaei, P. Boustead

Faculty of Informatics - Papers (Archive)

The popularity of on-line games that emphasize real-time interactivity is on the rise. A survey of issues and techniques for supporting on-line games is provided in this paper. Latency and scalability are two primary aspects on which this survey is based. Network latency heavily influences the design of on-line games with regards to the nature of interactivities involved, as well as, real-time flows such as voice and video if enhanced user immersive experiences are required. As a consequence, a trade-off between consistency and responsiveness, the two latency-related artifacts, is usually needed. This can be demonstrated through a number of latency …

Rendering Models For Immersive Voice Communications Within Distributed Virtual Environment, Ying Peng Que, P. Boustead, Farzad Safaei Jan 2005

Rendering Models For Immersive Voice Communications Within Distributed Virtual Environment, Ying Peng Que, P. Boustead, Farzad Safaei

Faculty of Informatics - Papers (Archive)

This paper compares three possible rendering models for the provision of Immersive Voice Communications (IVCs) in Distributed Virtual Environments (DVEs) such as multiplayer online games. The common aim of these three rendering models is to create a personalised auditory scene for each listening avatar, consisting of a mix of the surrounding avatars' voices, positioned according to their positions in the virtual world. The first two rendering models are based on amplitude panning localisation and HRTF-based binaural localisation respectively. The computation cost of the latter is deemed too large to meet the identified processing power constraints. A computation reuse scheme was …

On Some Applications Of Hadamard Matrices, Jennifer Seberry, Beata J. Wysocki, Tadeusz A. Wysocki Jan 2005

On Some Applications Of Hadamard Matrices, Jennifer Seberry, Beata J. Wysocki, Tadeusz A. Wysocki

Faculty of Informatics - Papers (Archive)

Modern communications systems are heavily reliant on statistical techniques to recover information in the presence of noise and interference. One of the mathematical structures used to achieve this goal is Hadamard matrices. They are used in many different ways and some examples are given. This paper concentrates on code division multiple access systems where Hadamard matrices are used for user separation. Two older techniques from design and analysis of experiments which rely on similar processes are also included. We give a short bibliography (from the thousands produced by a google search) of applications of Hadamard matrices appearing since the paper …

The Role Of Small Business Clusters In Prioritising Barriers To E-Commerce Adoption: A Study Of Swedish Regional Smes, Robert Macgregor, Lejla Vrazalic Jan 2005

The Role Of Small Business Clusters In Prioritising Barriers To E-Commerce Adoption: A Study Of Swedish Regional Smes, Robert Macgregor, Lejla Vrazalic

Faculty of Informatics - Papers (Archive)

Despite government initiatives, studies show that SME still fail to realise the benefits of e-commerce adoption. This paper extends existing research by showing that the barriers to e-commerce adoption can be grouped according to two distinct factors: the difficulty of implementing e-commerce and the unsuitability of e-commerce to the business. The paper also shows that the relative importance of these two factors is affected by membership/non-membership of a small business cluster.

A Study On The Charge-Discharge Mechanism Of Co3o4 As An Anode For The Li Ion Secondary Battery, Yong-Mook Kang, Min-Sang Song, Jin-Ho Kim, Hyun-Seok Kim, Min-Sik Park, Jai-Young Lee, Hua-Kun Liu, S X. Dou Jan 2005

A Study On The Charge-Discharge Mechanism Of Co3o4 As An Anode For The Li Ion Secondary Battery, Yong-Mook Kang, Min-Sang Song, Jin-Ho Kim, Hyun-Seok Kim, Min-Sik Park, Jai-Young Lee, Hua-Kun Liu, S X. Dou

Australian Institute for Innovative Materials - Papers

Co3O4 has shown acceptable electrochemical properties as the anode material of Li secondary batteries. In detail, its capacity reached about 700 mAh/g, twice as high as graphite, and 93.4% of initial capacity was retained after 100 cycles. EIS (electrochemical impedance spectroscopy) analyses revealed that after the 1st cycle, the insertion or extraction of Li ions in Co3O4 can occur homogeneously and reversibly (randless-like behavior, homogeneous mixture: Co + Li2O (in the state of Li insertion), Co3O4 (in the state of Li extraction)). In fact, the coulombic efficiency of Co …

A New Magnetoplasmon Sound Wave In A Two-Dimensional Electron Gas Under Electromagnetic Radiation, C Zhang, S Hessami Pilehrood

Australian Institute for Innovative Materials - Papers

We report a new magnetoplasmon mode and a sound-like collective excitation in two-dimensional electronic systems under a weak magnetic field and a low-frequency electromagnetic radiation. The analysis is based on the exact time-dependent wave functions and the exact relation between response function with and without radiation. The new mode discovered here can be used as a generating mechanism of high-frequency radiation from a system whose characteristic energy is low.

Nonmagnetic Insulator State In Na1coo2 And Phase Separation Of Na Vacancies, C De Vaulx, M. -H Julien, C Berthier, M Horvatic, P Bordet, V Simonet, Dapeng Chen, C T. Lin Jan 2005

Nonmagnetic Insulator State In Na1coo2 And Phase Separation Of Na Vacancies, C De Vaulx, M. -H Julien, C Berthier, M Horvatic, P Bordet, V Simonet, Dapeng Chen, C T. Lin

Australian Institute for Innovative Materials - Papers

Crystallographic, magnetic, and NMR properties of a NaxCoO2 single crystal with x≃1 are presented. We identify the stoichiometric Na1CoO2 phase, which is shown to be a nonmagnetic insulator, as expected for homogeneous planes of Co3+ ions with S=0. In addition, we present evidence that, because of slight average Na deficiency, chemical and electronic phase separation leads to a segregation of Na vacancies into the well-defined, magnetic, Na0.8CoO2 phase. The importance of phase separation is discussed in the context of magnetic order for x≃0.8 and the occurrence of a metal-insulator transition for x→1.

1-(4-Chlorophenyl)-2-Methyl-4-Nitro-5-(1-Piperidyl)-1h-Imidazole, Maciej Kubicki, Pawel Wagner

Australian Institute for Innovative Materials - Papers

The only specific interactions that influence the crystal packing of the title compound, C15H17ClN4O2, are weak C-H...N and C-H...Cl hydrogen bonds, even though there is a possibility of, for example, pi-pi stacking or halogen bonding. The dihedral angle between the mean planes of the imidazole and benzene rings is 59.82 (5) degrees . The length of the C-N bond connecting the imidazole and piperidine fragments is correlated with the degree of pyramidalization of the piperidine N atom.

Radiocarbon In Corals From The Cocos (Keeling) Islands And Implications For Indian Ocean Circulation, Q Hua, Colin D. Woodroffe, Scott Smithers, M Barbetti, David Fink Jan 2005

Radiocarbon In Corals From The Cocos (Keeling) Islands And Implications For Indian Ocean Circulation, Q Hua, Colin D. Woodroffe, Scott Smithers, M Barbetti, David Fink

Faculty of Science - Papers (Archive)

Annual bands of a Porites coral from the Cocos (Keeling) Islands, eastern Indian Ocean, were analysed by radiocarbon for 1955–1985 AD. A rapid oceanic response of the site to bomb 14C is found, with a maximum D14C value of 132% in 1975. This value is considerably higher than those for the northwestern Indian Ocean, suggesting that surface waters reaching Cocos are not derived from the Arabian Sea. Instead, D14C values for Cocos and those for Watamu (Kenya) agree well over most of the study interval, suggesting that the South Equatorial Current carries 14C-elevated water rather than 14C-depleted water westward across …

Palaeovolcanic Forcing Of Short-Term Dendroisotopic Depletion: The Effect Of Decreased Solar Intensity On Irish Oak, N. Ogle, Christian Turney, R.M. Kalin, L. O'Donnell, C.J. Butler Jan 2005

Palaeovolcanic Forcing Of Short-Term Dendroisotopic Depletion: The Effect Of Decreased Solar Intensity On Irish Oak, N. Ogle, Christian Turney, R.M. Kalin, L. O'Donnell, C.J. Butler

Faculty of Science - Papers (Archive)

The climatic effects of historical volcanic eruptions are well documented in the literature. What are less certain however, are the effects of eruptions on more distant environments, particularly vegetation. Here we present sub-annual δ13C records from two high-resolution Irish oak (Quercus spp.) chronologies that span the Laki (Grímsvötn) 1783–84 and Tambora 1815 eruptions. In both instances, a significant depletion in δ13C is recorded within the trees following the eruption (∼1.8‰). Historical meteorological datasets from observatories near to the trees sampled demonstrate that the shifts in carbon isotopic content cannot be accounted for by changes in …

Structural Re-Assignment Of The Mono- And Bis-Addition Products From The Addition Reactions Of N-(Diphenylmethylene)Glycinate Esters To [60]Fullerene Under Bingel Conditions, Graham E Ball, Glenn Ashley Burley, Leila Chaker, William Hawkins, James Williams, Paul A. Keller, Stephen G. Pyne Jan 2005

Structural Re-Assignment Of The Mono- And Bis-Addition Products From The Addition Reactions Of N-(Diphenylmethylene)Glycinate Esters To [60]Fullerene Under Bingel Conditions, Graham E Ball, Glenn Ashley Burley, Leila Chaker, William Hawkins, James Williams, Paul A. Keller, Stephen G. Pyne

Faculty of Science - Papers (Archive)

The addition of N-(diphenylmethylene)glycinate esters (Ph2C=NCH2CO2R) to [60]fullerene under Bingel conditions gives [60]fullerenyldihydropyrroles and not methano[60]fullerenyl iminoesters [C60C(CO2R)(N=CPh2)] as previously reported. Unequivocal evidence for the structure of C60C(CO2Et)(N=CPh2) was provided by INADEQUATE NMR studies on 13C enriched material. New mechanistic details are proposed to account for the formation of [60]fullerenyldihydropyrroles and their reductive ring-opening reactions.

No Academic Borders?: Transdisciplinarity In University Teaching And Research, Alice W. Russell Jan 2005

No Academic Borders?: Transdisciplinarity In University Teaching And Research, Alice W. Russell

Faculty of Science - Papers (Archive)

Transdisciplinarity has been a veritable mantra, especially in the humanities and social sciences, for twenty years or more. Yet academic structures and research application requirements still struggle to come to grips with crossboundary research and teaching. Making universities more trans-discipline-friendly is a tricky task, however. As Wendy Russell explains, trans-disciplines require disciplines, and disciplinary boundaries, too.

Combined Effects Of Solar Radiation And Desiccation On The Mortality And Development Of Encapsulated Embryos Of Rocky Shore Gastropods, R. Przeslawski Jan 2005

Combined Effects Of Solar Radiation And Desiccation On The Mortality And Development Of Encapsulated Embryos Of Rocky Shore Gastropods, R. Przeslawski

Faculty of Science - Papers (Archive)

Intertidal encapsulated embryos may be synchronously exposed to many environmental stressors, but interactions between some of these factors remain poorly understood. Here, the effects of solar radiation and desiccation on embryonic mortality and developmental rates were assessed using laboratory and field experiments. Egg masses of 3 intertidal gastropod species were exposed for 72 h to combinations of spectral (full spectrum, UV-blocked, dark) and daily emersion treatments (control, 15, 30, 60 min). Siphonaria denticulata and Bembicium nanum embryos were expected to be tolerant to emersion and UVR as they are routinely deposited on exposed rock platforms. In contrast, Dolabrifera brazieri embryos …

[Extract] During Easter in 2000 we (AP and NG) were in Central Australia during heavy rainfalls and flooding. Roads were cut and we were stuck in Tennant Creek. We decided to review documents held by the local museum. This included material used in the late 1970s to compile a general history of Tennant Creek, the only such work of which we are aware. It was interesting to note that in one case the author had written to a pastoralist they had recently visited, and included a section describing the role of Aboriginal people at their station.

Beyond Yellowstone? Conservation And Indigenous Rights In Australia And Sweden, Michael Adams Jan 2005

Beyond Yellowstone? Conservation And Indigenous Rights In Australia And Sweden, Michael Adams

Faculty of Science - Papers (Archive)

Faced with the paradox of a large global increase in conservation reserves and a simultaneous global decrease in actual effective protection for biodiversity, conservation scientists and others are questioning established conservation theory and practice. Conservation is largely a ‘residual’ landuse, which often conflicts with another residual landuse, the remaining lands owned or accessed by Indigenous peoples. I argue that the Western conservation model has created this situation, and that engaging with Indigenous ways of relating to ‘nature’ could lead to improved outcomes. From the basis that environmental problems are fundamentally social problems, and using case studies from Australia and Sweden, …
