Human Detection Using Local Shape And Non-Redundant Binary Patterns, Duc Thanh Nguyen, Wanqing Li, Philip Ogunbona Jan 2010

Human Detection Using Local Shape And Non-Redundant Binary Patterns, Duc Thanh Nguyen, Wanqing Li, Philip Ogunbona

Faculty of Informatics - Papers (Archive)

Motivated by the advantages of using shape matching technique in detecting objects in various postures and viewpoints and the discriminative power of local patterns in object recognition, this paper proposes a human detection method combining both shape and appearance cues. In particular, local shapes of the body parts are detected using template matching. Based on body parts' shapes, local appearance features are extracted. We introduce a novel local binary pattern (LBP) descriptor, called Non-Redundant LBP (NRLBP), to encode local appearance of human. The proposed method was evaluated and compared with other state-of-the-art human detection methods on two commonly used datasets: …

Business Relationships In China: Lessons About Deep Trust, A. Kriz, Byron W. Keating Jan 2010

Business Relationships In China: Lessons About Deep Trust, A. Kriz, Byron W. Keating

Faculty of Informatics - Papers (Archive)

Trust is acknowledged as a central tenet of business relationships. Yet for all the attention it receives, rarely has trust been investigated in the Chinese business setting. This paper uses an emic approach to unearth some within- culture ‘truths’ about Chinese notions of trust in business exchange. The findings of this research suggest that deep trust (xinren), which is driven by reciprocal help and emotional bonding, is critical for doing business in China. A conceptual framework is provided to assist Western businesspersons to better understand the Chinese concept of trust as well as the interplay between its key antecedents.

Unpacking The Rfid Investment Decision, Byron W. Keating, Tim R. Coltman, Samuel Fosso Wamba, Valerie Baker Jan 2010

Unpacking The Rfid Investment Decision, Byron W. Keating, Tim R. Coltman, Samuel Fosso Wamba, Valerie Baker

Faculty of Informatics - Papers (Archive)

Mandates aside, there are many reasons why firms decide to move forward with or delay investment in RFID technology. In this paper we use a theoretically based, easy to implement methodology to empirically derive a relative importance scale of those factors that influence the decision to invest in RFID technology. More specifically, we compare the factors that matter most and least to a sample of firms that have adopted RFID technology with a sample of firms that have yet to embrace RFID technology. The theoretical and practical implications are that both RFID adopters and non adopters are driven by the …

Head-Tracking Haptic Computer Interface For The Blind, Simon Meers, Koren Ward Jan 2010

Head-Tracking Haptic Computer Interface For The Blind, Simon Meers, Koren Ward

Faculty of Informatics - Papers (Archive)

In today’s heavily technology-dependent society, blind and visually impaired people are becoming increasingly disadvantaged in terms of access to media, information, electronic commerce, communications and social networks. Not only are computers becoming more widely used in general, but their dependence on visual output is increasing, extending the technology further out of reach for those without sight. For example, blindness was less of an obstacle for programmers when command-line interfaces were more commonplace, but with the introduction of Graphical User Interfaces (GUIs) for both development and final applications, many blind programmers were made redundant (Alexander, 1998; Siegfried et al., 2004). Not …

Realigning Service Operations Strategy At Dhl Express, Tim R. Coltman, John Gattorna, Stuart Whiting Jan 2010

Realigning Service Operations Strategy At Dhl Express, Tim R. Coltman, John Gattorna, Stuart Whiting

Faculty of Informatics - Papers (Archive)

This paper describes the approach that DHL used to respond to aggressive revenue and profit targets set by its Asia-Pacific regional management board. DHL’s reaction to these targets was to redefine its strategic service vision by systematically aligning its internal support functions with distinct buyer behavior structures. Specifically, we developed a model based on the tangible and intangible factors that directly influence a customer’s choice of a third-party logistics provider. Next, we reverse engineered the service provider’s delivery system to align with each customer’s preferred buying behavior. DHL’s share of wallet and profitability immediately improved, enabling the company to maintain …

Dimensionality Reduction Using Compressed Sensing And Its Application To A Large-Scale Visual Recognition Task, Son Lam Phung, Fok Hing Chi Tivive, Abdesselam Bouzerdoum, Jie Yang Jan 2010

Dimensionality Reduction Using Compressed Sensing And Its Application To A Large-Scale Visual Recognition Task, Son Lam Phung, Fok Hing Chi Tivive, Abdesselam Bouzerdoum, Jie Yang

Faculty of Informatics - Papers (Archive)

This paper presents a novel algorithm for the dimensionality reduction which employs compressed sensing (CS) to improve the generalization capability of a classifier, especially for large-scale data. Compared to traditional dimensionality reduction methods, the proposed algorithm makes no use of the problem-dependent parameters, nor does it require additional computation for the eigenvalue decomposition like PCA or LDA. Mathematically, the derived algorithm regards the input features as the dictionary in CS, and selects the features that minimize the residual output error iteratively, thus the resulting features have a direct correspondence to the performance requirements of the given problem. Furthermore, the proposed …

On The Analysis Of Background Subtraction Techniques Using Gaussian Mixture Models, Abdesselam Bouzerdoum, Azeddine Beghdadi, Son Lam Phung, Philippe L. Bouttefroy Jan 2010

On The Analysis Of Background Subtraction Techniques Using Gaussian Mixture Models, Abdesselam Bouzerdoum, Azeddine Beghdadi, Son Lam Phung, Philippe L. Bouttefroy

Faculty of Informatics - Papers (Archive)

In this paper, we conduct an investigation into background subtraction techniques using Gaussian Mixture Models (GMM) in the presence of large illumination changes and background variations. We show that the techniques used to date suffer from the trade-off imposed by the use of a common learning rate to update both the mean and variance of the component densities, which leads to a degeneracy of the variance and creates “saturated pixels”. To address this problem, we propose a simple yet effective technique that differentiates between the two learning rates, and imposes a constraint on the variance so as to avoid the …

A Training Algorithm For Sparse Ls-Svm Using Compressive Sampling, Jie Yang, Son Lam Phung, Abdesselam Bouzerdoum Jan 2010

A Training Algorithm For Sparse Ls-Svm Using Compressive Sampling, Jie Yang, Son Lam Phung, Abdesselam Bouzerdoum

Faculty of Informatics - Papers (Archive)

Least Squares Support Vector Machine (LS-SVM) has become a fundamental tool in pattern recognition and machine learning. However, the main disadvantage is lack of sparseness of solutions. In this article Compressive Sampling (CS), which addresses the sparse signal representation, is employed to find the support vectors of LS-SVM. The main difference between our work and the existing techniques is that the proposed method can locate the sparse topology while training. In contrast, most of the traditional methods need to train the model before finding the sparse support vectors. An experimental comparison with the standard LS-SVM and existing algorithms is given …

Markov Random Fields For Abnormal Behavior Detection On Highways, Son Lam Phung, Philippe L. Bouttefroy, Abdesselam Bouzerdoum, Azeddine Beghdadi Jan 2010

Markov Random Fields For Abnormal Behavior Detection On Highways, Son Lam Phung, Philippe L. Bouttefroy, Abdesselam Bouzerdoum, Azeddine Beghdadi

Faculty of Informatics - Papers (Archive)

This paper introduces a new paradigm for abnormal behavior detection relying on the integration of contextual information in Markov random fields. Contrary to traditional methods, the proposed technique models the local density of object feature vector, therefore leading to simple and elegant criterion for behavior classification. We develop a Gaussian Markov random field mixture catering for multi-modal density and integrating the neighborhood behavior into a local estimate. The convergence of the random field is ensured by online learning through a stochastic clustering algorithm. The system is tested on an extensive dataset (over 2800 vehicles) for behavior modeling. The experimental results …

Australian Institute for Innovative Materials - Papers

Organic functionalization of non-oxidized silicon surfaces, while allowing for robust chemical passivation of the inorganic substrate, is intended and expected to broaden the chemical, physical and electronic properties of the currently most relevant technological material. Numerous protocols are now available for the preparation of Si-C, Si-O and Si-N bound layers. In particular, the covalent attachment of 1-alkenes and 1-alkynes onto hydride-terminated Si(100) and Si(111) has seen a wealth of research activity starting from the pioneering work of Linford and Chidsey (Alkyl monolayers covalently bonded to silicon surfaces, J. Am. Chem. Soc., 1993, 115(26), 12631-12632). This critical review aims to bring …

Australian Institute for Innovative Materials - Papers

The structural and magnetic properties of Ho2Fe17−xMnx (x=0-5) have been investigated by x-ray diffraction, Mössbauer spectroscopy and DC magnetization measurements (0-5 T) over the temperature range 4.5-350 K. Similar to other ferrimagnetic R2Fe17-xMnx systems, the unit cell volume generally increases with Mn content other than for low Mn values where a slight maximum is detected around x ∼ 0.5. The nature of the magnetic phase transitions around TC is shown by Arrot plot analysis to be second order for all samples. The Curie temperature remains essentially unchanged …

Magnetic Properties Of La Doped Bi2femno6 Ceramic And Film, Hongyang Zhao, Hideo Kimura, Zhenxiang Cheng, Xiaolin Wang, Kiyoshi Ozawa, Takashi Nishida

Australian Institute for Innovative Materials - Papers

We present a comprehensive study of the magnetic properties for La doped Bi2FeMnO6 (LBFM) ceramic and film which was first deposited on (100) SrTiO3 substrate by pulsed laser deposition method. The LBFM film is antiferromagnetic or weak ferrimagnetic at room temperature and it shows clear magnetic anisotropy. But it is not sure whether the spin-glass behavior is present in LBFM film because of the influence from substrate. Compared to the film, LBFM ceramic shows different magnetic properties. It has a lower TN and all the observations indicate that LBFM ceramic shows spin-glass behavior.

Intergrain Connectivity Of Mgb2 Ceramics Studied By Impedance Analysis, C.C Wang, C Wang, Rong Zeng, S X. Dou

Australian Institute for Innovative Materials - Papers

First, by using of the conventional Rowell analysis, we demonstrated that the addition of nano BN particles can effectively eliminate MgO and pores in MgB2 resulting in a very high density and good connectivity of BN-doped MgB2. Then, another method—low-frequency dielectric impedance analysis—was introduced to characterize the properties of the grain boundaries of MgB2. A comparative impedance study was performed in the frequency range from 100 Hz to 100 MHz on pure and nano BN-doped MgB2. The study revealed some following interesting results: (1) a dielectric resonance around frequency of 108 in both samples …

Australian Institute for Innovative Materials - Papers

We report synthesis, structural details, and magnetization of SmFe1-xCoxAsO with x ranging from 0.0 to 0.30. It is found that Co substitutes fully at Fe site in SmFeAsO in an isostructural lattice with slightly compressed cell. The parent compound exhibited known as the spin density wave (SDW) character is below at around 140 K. Successive doping of Co at Fe site suppressed the SDW transition for x=0.05 and later induced superconductivity for x=0.10, 0.15, and 0.20, respectively, at 14, 15.5, and 9 K. The lower critical field as seen from magnetization measurements is below 200 Oe. …

Magnetic Properties Of Bi2femno6: A Multiferroic Material With Double-Perovskite Structure, Yi Du, Zhenxiang Cheng, S X. Dou, Xiaolin Wang, Hua Zhao, Hideo Kimura

Australian Institute for Innovative Materials - Papers

Single phase Bi2FeMnO6 was synthesized on Si substrates by an electrospray method. Three peaks were observed in the temperature dependence of magnetization curve, which is attributed to the inhomogeneous distribution of Fe3+ and Mn3+. The observed magnetic peaks at 150 K, 260 K, and 440 K correspond to orderings of the ferrimagnetic Fe–O–Mn, and antiferromagnetic Mn–O–Mn and Fe–O–Fe, respectively. Heat capacity measurements were carried out to confirm these magnetic transitions. The Debye temperature of Bi2FeMnO6 is 339 K, calculated from Debye–Einstein fitting.

Pluripotent Human Stem Cells, Blaine W. Phillips, Jeremy M. Crook Jan 2010

Pluripotent Human Stem Cells, Blaine W. Phillips, Jeremy M. Crook

Australian Institute for Innovative Materials - Papers

The need for new and improved pharmacotherapies in medicine, high late-stage compound attrition in drug discovery, and upcoming patent expirations is driving interest by the pharmaceutical industry in pluripotent stem cells for in vitro modeling and early-stage testing of toxicity and target engagement. In particular, human embryonic and induced pluripotent stem cells represent potentially cost-effective and accessible sources of organ-specific cells that foretell in vivo human tissue response to new chemical entities. Here we consider the potential of these cells as novel tools for drug development, including toxicity screening and metabolic profiling. We hold that despite various challenges to translating …

Late Quaternary Morphodynamics In The Quebrada De Purmamarca, Nw Argentina, Jan-Hendrik May, Ramiro Daniel Soler Jan 2010

Late Quaternary Morphodynamics In The Quebrada De Purmamarca, Nw Argentina, Jan-Hendrik May, Ramiro Daniel Soler

Faculty of Science - Papers (Archive)

This study aims to document the geomorphic, sedimentary and paleopedogenic archives in the Quebrada de Purmamarca. The paleoenvironmental interpretation of these archives and the reconstruction of landscape evolution are mainly based on field observations and geomorphological mapping (May 2008). A series of aggradational terraces mostly consisting of coarse debris-flow deposits are the main focus of this investigation. While the associated cut-and-fill processes are probably the result of an interplay between climatic and tectonic controls, the deposition of the youngest terrace level (> 150 m thickness) may likely be attributed to a drop of the periglacial belt of more than 1000 …

Assessing The Vulnerability Of Asian Megadeltas To Climate Change Using Gis, Colin D. Woodroffe

Faculty of Science - Papers (Archive)

Susceptibility of Asian megadeltas to climate change, including sea-level rise, is investigated using GIS. The Indus, Ganges-Brahmaputra-Meghna, Irrawaddy, Chao Phraya, Mekong, Red, Pearl, Changjiang, and Huanghe deltas began to form around 6000 years ago and have prograded since. The surface topography of active and abandoned delta plains is examined using digital terrain models derived from Shuttle Radar Topography Mission data and channel morphology is investigated using radar imagery. After delta plains are abandoned they become increasingly dominated by tidal processes. Population density is estimated using gridded world population data but highly variable local microtopography and uncertainty regarding future climate changes …

Application Of A Simple Hydrodynamic Model To Estuary Entrance Management, Errol J. Mclean, Jon B. Hinwood Jan 2010

Application Of A Simple Hydrodynamic Model To Estuary Entrance Management, Errol J. Mclean, Jon B. Hinwood

Faculty of Science - Papers (Archive)

Tidal inlets which link a tidal basin to the sea via a constricted entrance are common on the south-east Australian coast. Closure, or even significant constriction, raises water levels but restricts tidal range within the basin, while open entrances provide regular and significant tidal exchange with the ocean. A rapid assessment procedure with minimal data requirements has been shown to be informative for monitoring and a useful component of any Decision Support System set up as part of a management structure. Such a system is presented in this paper. It is based on one permanent water level gauge inside the …
