Recommended Procedures for Determination of Distribution Widths in the Design of Stress Laminated Timber Plate Decks

Crews Keith (CIB - International Council for research and innovation in building and construction, 2006)

NA
Relative Distance Estimation for Indoor Multi-Robot Control Using Monocular Digital Camera

Yu Ying Hao; Kodagoda Sarath; Ha Quang (The University of Tasmania, 2009)

Distance measurement methodologies based on the digital camera usually require extensive calibration routines, some are even derived from complicated image processing algorithms resulting in low picture frame rates. ...
Remote Laboratories in Engineering Education: Trends in Students' Perceptions

Lindsay Euan; Liu Dikai; Murray Stephen; Lowe David (Australasian Association for Engineering Education, 2007)

Remotely accessible laboratories are an increasingly popular innovation in engineering education. Since 2001, The University of Technology, Sydney has implemented a number of remotely accessible laboratories. This paper ...
Replanning of Multiple Autonomous Vehicles in Material Handling

Paul Gavin; Liu Dikai (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2006)

The fully automated docks in Australia present opportunities for applications of autonomous vehicles and engineering innovation. When planning tasks to be done by multi-autonomous vehicles in an enclosed area with a ...
Residual Swirl in Axial-Flow Pump

Revel Alex; Parmigiani H S; Huynh Ba (Adelaide University, 2001)

Measurements of residual swirl in an industry-size axial-flow pump unit have been conducted, using a Fechheimer probe. They reveal that even though the unit's components have been constructed according to well established ...
Review of wave energy resource and oscillating water column modelling

Dorrell David; Halliday J; Miller P; Findlater M (The University of the West of England (UWE), 2004)

Wave energy as a means of generating electricity has been the focus of study in thc UK for over thirty years, albeit in a low key manner and with little public support. Interest is now growing. This paper is dividcd into ...
Ride Simulations of a Half-car with a Hydraulically Interconnected Passive Suspension

Zhang Nong; Smith Wade; Jeyakumaran Jeku (Society of Automotive Engineers of Japan Inc, 2006)

In this paper, the development of a hydraulically interconnected suspension (HIS) system model and the integration of this model into a four degree-of-freedom half-car system is briefly introduced. The appropriate frequency ...
Road Curb and Intersection Detection using a 2D LMS

Kodagoda Sarath; Balasuriya Arjuna; Wijesoma W (IEEE, 2002)

In most urban roads and similar environments, such as in theme parks, campus sites, industrial estates, science parks and the like, the painted lane markings that exist may not be easily discernible by CCD cameras due to ...
Road Edge and Lane Boundary Detection using Laser and Vision

Teoh Eam; Wijesoma W; Balasuriya Arjuna; Kodagoda Sarath (IEEE, 2001)

This paper presents a methodology for extracting road edge and lane information for smart and intelligent navigation of vehicles. The range information provided by a fast laser range-measuring device is processed by an ...
Robotic formation control using variable structure systems approach

Ha Huy Minh; Ha Quang; Dissanayake Gamini (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2006)

This paper addresses robust control of multiple mobile robots moving in desired formations. A rigorous control technique for such an agent-based robotic system may encounter problems of singularity, parameter sensitivity ...
A robotic system for steel bridge maintenance: research challenges and system design

Liu Dikai; Dissanayake Gamini; Manamperi Palitha; Fang Gu; Paul Gavin; Kirchner Nathan; Chotiprayanakul Pholchai (Australian Robotics and Automation Association, 2008)
Robust Active Roll Controller Design for Vehicles Considering Variable Speed and Actuator Delay

Zhang Nong; Du Haiping; Dong Guangming (SAE, 2007)

A robust controller design method for vehicle roll control with variable speed and actuator delay is presented. Based on a three-degree-of-freedom (3DOF) yaw-roll model, the H􀂒 performance from the steering input to ...
Robust Control for Nonlinear Discrete-Time Systems with Quantitative Input to State Stability Requirement

Huang Shoudong; Su Steven (2008 IFAC, 2008)

In this paper, we consider state feedback robust control problems for discretetime nonlinear systems subject to disturbances. The objective of the control is to minimize a performance function while guaranteeing a prescribed ...
Robust Multivariable Strategy and its Applications to a Powered Wheelchair

Nguyen Tuan; Nguyen Hung; Su Steven (IEEE, 2009)

The paper proposes a systematic robust multivariable control strategy based on combination of systematic triangularization technique and robust control strategies. Two design stages are required. In the first design stage, ...
Robust Optimization in HTS Cable Based on DEPSO and Design for Six Sigma

Wang Shuhong; Liu Xinying; Qiu Jie; Zhu Jianguo; Guo Youguang; Lin Zhi Wei (Jack) (IEEE, 2008)

The non-uniform AC current distribution among the multi-layer conductors in a high-temperature superconducting (HTS) cable reduces the current capacity and increases the AC loss. In this paper, Particle swarm optimization ...
Role of Plant Buildings in a Power Station Acting as a Barrier to the Wind Affecting the Natural Draft Cooling Tower Performance

Amur Ghulam; Milton Brian; Reizes John; Madadnia Jafar; Beecham Simon; Brady Peter; Koosha Homa (University of Sydney, 2004)
