Active Seismic response control of tall buildings based on reduced order model

Boffa John; Du Haiping; Zhang Nong (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2006)

This paper applies the dynamic model reduction method to obtain a reduced order model of an experimental tall building which has twenty floors and is 2.5m high. The experimental model is designed to imitate a real tall ...
Active SLAM for structured environments

Leung Cindy; Dissanayake Gamini; Huang Shoudong (IEEE, 2008)

This paper considers the trajectory planning problem for line-feature based SLAM in structured indoor environments. The robot poses and line features are estimated using smooth and mapping (SAM) which is found to provide ...
Active structural control using dymanic output feedback sliding mode

Ha Quang; Li Jianchun; Hong Guang; Samali Bijan (ARAA (Australian Robotics & Automation Association), 2001)

This paper presents a dynamic output feedback control approach to active control of civil engineering structures. The design is based on sliding mode control, pole placement of the closed-loop eigenvalues, and linear ...
Adaptive EEG thought pattern classifier for advanced wheelchair control

Craig Daniel; Nguyen Hung (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2007)

This paper presents a real-time Electroencephalogram (EEG) classification system, with the goal of enhancing the control of a head-movement controlled power wheelchair for patients with chronic Spinal Cord Injury (SCI). ...
Adaptive shared control strategies based on the Bayesian recursive technique for an intelligent wheelchair

Trieu Tuyen; Willey Keith; Nguyen Hung (IEEE, 2009)

In this paper we present an adaptive shared control method for an intelligent wheelchair based on the Bayesian recursive technique to assist a disable user in performing obstacle avoidance tasks. Three autonomous tasks ...
Adaptive sliding mode control for civil structure using magnetorheological dampers

Kwok Ngai Ming; Ha Quang; Nguyen Thanh; Li Jianchun; Samali Bijan (Japan Robot Association, 2006)

An adaptive sliding mode controller for vibration control is proposed in this paper for structures embedded with magnetorheological (MR) dampers. Civil structures and buildings are liable to damages during earthquake ...
Adaptive Web Navigation Construction: A Machine Learning Approach

Kong Xiaoying; Gu Y; Lowe David (Electronic Commerce Research Unit ECRU, 2006)

Support for effective stakeholder interaction with an organization's web site has increasingly played a critical role in business success. An important factor in this effective web interaction is the ease with which a ...
Advanced Obstacle Avoidance for a Laser-based Wheelchair using Optimised Bayesian Neural Networks

Trieu Tuyen; Nguyen Hung; Willey Keith (IEEE, 2008)

In this paper we present an advanced method of obstacle avoidance for a laser based intelligent wheelchair using optimized Bayesian neural networks. Three neural networks are designed for three separate sub-tasks: passing ...
Advanced robust tracking control of a powered wheelchair

Nguyen Hung; Nguyen Tuan; Su Steven (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2007)

Alumina-Silica Rich Clay Brick Waste In Hydrothermally Treated Cement-Based Construction Products

Ray Abhi; Connan Hamish; Liu Barry; Thomas Paul (CI-Premier Conference Organisation, Singapore, 2009)

An urgent need for creative, sustainable approaches, which minimise the environmental impact of conventional Portland Cement (PC) -based construction materials, is recognised throughout the world. In recent years intensive ...
Analysis of axial voltages and inter-bar currents in cast copper cage rotors during DC current injection as an aid to identify casting faults

Dorrell David; Frosini Lucia; Bottani Marcello; Galbiati Giacomo; Hsieh Min-Fu (IEEE, 2009)
