HDAX: Historical Symbolic Modelling of Delay Time Series in a Communications Network

Homayounfard Hooman; Kennedy Paul (Australian Computer Society, 2009)

There are certain performance parameters like packet delay, delay variation (jitter) and loss, which are decision factors for online quality of service (QoS) traffic routing. Although considerable efforts have been placed ...
Head Detection For Video Surveillance Based On Categorical Hair And Skin Colour Models

Zhang Zui; Piccardi Massimo; Gunes Hatice (IEEE, 2009)

We propose a new robust head detection algorithm that is capable of handling significantly different conditions in terms of viewpoint, tilt angle, scale and resolution. To this aim, we built a new model for the head based ...
A hierarchically combined classifier for license plate recognition

He Xiangjian; Zheng Lihong; Wu Qiang; Jia Wenjing; Samali Bijan; Palaniswami Marimuthu (IEEE Computer Society, 2008)

High accuracy and fast recognition speed are two requirements for real-time and automatic license plate recognition system. In this paper, we propose a hierarchically combined classifier based on an inductive learning based ...
Higher order prediction for sub-pixel motion estimation

Yang Jie; Mudugamuwa Damith; Ahn Chung-Hyun; He Xiangjian (IEEE, 2009)

A Highly Accurate Algorithm for the Estimation of the Frequency of a Complex Exponential in Additive Gaussian Noise

Reisenfeld Sam (Australian National University, 2004)

A new algorithm for the precise estimation of the frequency of a complex exponential signal ill additive, complex, white Gaussian noise is presented. The algorithm has low computational complexity and is well suited for ...
High-Speed Feature Extraction in Sensor Coordinates for Laser Rangefinders

Alempijevic Alen (ARAA (Australian Robotics & Automation Association), 2004)

The main contributions of this paper are two algorithms for extracting lines and comers present in the environment from information gathered by a laser rangefinder. The laser range scan is processed in its natural ...
How it feels, not just how it looks: when bodies interact with technology

Robertson Toni; Larssen Astrid Twenebowa; Edwards Jennifer (Computer-Human Interaction Special Interest Group, 2006)

This paper presents thoughts to extend our understanding of bodily aspects of technology interactions. The aim of the paper is to offer a way of looking at the role our kinaesthetic sense plays in human-computer ...
How Pseudo Model May Help Evaluate Image Compression on Spiral Architecture

Wang Huaqing; Hintz Thomas; He Xiangjian; Wu Qiang (CSREA Press, 2004)
Human Action Recognition by Radon Transform

Chen Yan; He Xiangjian; Wu Qiang (IEEE, 2008)

A new feature description is used for human behaviour representation and recognition. The feature is based on Radon transforms of extracted silhouettes. Key postures are selected based on the Radon transform. Key postures ...
A hybrid CME-LS channel estimation approach for broadband MIMO-OFDM systems

Lu Zhen; Kadi Anthony; Aubrey Timothy (IEEE, 2009)

A channel estimation approach yielding both channel gains and the number of multi-paths is presented. The algorithm is based on a variation of conditional model order estimation (CME), and is proposed for MIMO-OFDM systems. ...
The impacts of non-functional requirements in web systems

Zowghi Didar; Yusop Norazlin; Lowe David (Brunel University, UK, 2006)

In Web system development, the non-functional requirements (NFRs) are typically considered only briefly during the requirements elicitation stage and not rigorously articulated by either Web developers or the client. ...
Implicit training of virtual shopping assistants in 3D electronic institutions

Bogdanovych Anton; Simoff Simeon; Sierra Carles; Berger Helmut (IADIS Press, 2005)

The growing demand for shopping assistants in E-Commerce was identified by many researchers. Some retailers try to address this need by introducing totally autonomous agents; others make extensive use of human resources, ...
Improvement of fractual image coding base on the different image

Wang Huaqing; He Xiangjian; Wu Qiang; Hintz Thomas (DSPCS, 2006)

In this paper, we propose an enhanced Fractal Image Compression (FIC) approach. In this method, the original image is represented by a provisional image and a difference image, which records the difference between ...
Improving graduate attributes with online teaching resources: A case study in IT management

Sixsmith Alan; Litchfield Andrew (Australasian Society for Computers in Tertiary Education, 2009)

The paper backgrounds the UTS Work-ready Project which aims to improve graduate professional attributes and employability understandings and skills. The Project makes available online teaching and learning resources to ...
Incorporating elements from the Prometheus agent-oriented methodology in the OPEN Process Framework

Tran Quynh-Nhu Numi; Henderson-Sellers Brian; Debenham John (Faculty of Computer Science and IT, Riga Technical University, 2004)

As part of an extensive research programme to combine the benefits of method engineering and existing object-oriented frameworks (notably the OPF) to create a highly supportive methodological environment for the construction ...
Industrial Perspectives on Architecture Level Change Impact Analysis in Web Systems Evolution

Mehboob Zafar; Zowghi Didar (IEEE, 2009)

Change impact analysis (CIA) approaches are mostly developed based on the understanding of both system development process and system architecture. It is thus reasonable to assume that if the development process or system ...
An Information-Based model for trust

Debenham John; Sierra Carles (Association for Computing Machinery, 2005)

In this paper we present a rich decision model for intelligent agents involved in multi issue negotiations. The model, grounded on information theory, takes into account the aspects of trust and preference to devise ...
Information-Based Planning and Strategies

Debenham John (Springer Verlag, 2008)

The foundations of information-based agency are described, and the principal architectural components are introduced. The agent¿s deliberative planning mechanism manages interaction using plans and strategies in the context ...
Information presentation and design for multilingual global e-commerce sites - a cultural aspect

Kang Kyeong-Soon; Underwood Jim (IADIS Press, 2005)

This paper addresses the design of web sites for companies engaged in global e-commerce. Different language groups and different cultures prefer different styled of web pages. In this paper we performed a comparative ...
Information Systems, Information sharing and Communities of Practice

Lueg Christopher; Riedl R (Korea Electromagnetic Engineering Society (KEES), 2001)

In this paper, we argue that information management and knowledge management share important characteristics and thus face similar challenges. Based on a discussion of information problems observed in a large and technically ...
