Dynamic Fingerprint Based On Human Motion And Posture, Amir Hesami, Fazel Naghdy, David Stirling
Dynamic Fingerprint Based On Human Motion And Posture, Amir Hesami, Fazel Naghdy, David Stirling
Faculty of Engineering and Information Sciences - Papers: Part A
The feasibility of generating a Dynamic FingerPrint (DFP) for an individual is explored. DFP is a unique signature generated based on a combination of body part movements. The body movements are obtained using a sensor suit recording inertial signals that are subsequently modeled on a humanoid frame with 23 degrees of freedom (DOF). Measured signals include position, velocity, acceleration, orientation, angular velocity and angular acceleration. DTW (Dynamic Time Warping) is XVHG WR FODVVLI\ WKH LQGLYLGXDO¶V identity. The approach is described and the characteristics of the algorithms are presented. It is anticipated that these approaches will have applications in surveillance and …
Electroactive Polymers As Soft Robotic Actuators: Electromechanical Modeling And Identification, Rahim Mutlu, Gursel Alici, Weihua Li
Electroactive Polymers As Soft Robotic Actuators: Electromechanical Modeling And Identification, Rahim Mutlu, Gursel Alici, Weihua Li
Faculty of Engineering and Information Sciences - Papers: Part A
Biologically inspired robotic applications have recently received significant attention due to developments in novel materials and actuators with an operation principle similar to the natural muscles’. Electroactive polymer (EAP) actuators, also known as artificial muscles, possess extraordinary properties such as low efficiency consumption, compliance, bio-compatibility and ability to be miniaturized. Although several methodologies have been proposed for modeling and identification of their quasi-static bending behavior, a negligibly small attention has been given to their dynamic behavior. In this paper, we, therefore, report on their electromechanical modeling and parameter identification. We model the tri-layer EAP actuators as a soft robotic actuator …
Two-Stage Through-The-Wall Radar Image Formation Using Compressive Sensing, Van Ha Tang, Abdesselam Bouzerdoum, Son Lam Phung
Two-Stage Through-The-Wall Radar Image Formation Using Compressive Sensing, Van Ha Tang, Abdesselam Bouzerdoum, Son Lam Phung
Faculty of Engineering and Information Sciences - Papers: Part A
We introduce a robust image-formation approach for through-the-wall radar imaging (TWRI). The proposed approach consists of two stages involving compressive sensing (CS) followed by delay-and-sum (DS) beamforming. In the first stage, CS is used to reconstruct a complete set of measurements from a small subset collected with a reduced number of transceivers and frequencies. DS beamforming is then applied to form the image using the reconstructed measurements. To promote sparsity of the CS solution, an overcomplete Gabor dictionary is employed to sparsely represent the imaged scene. The new approach requires far fewer measurement samples than the conventional DS beamforming and …
A Literature Review On Business Process Management, Business Process Reengineering, And Business Process Innovation, Abhijith Anand, Samuel Fosso Wamba, Denis Gnanzou
A Literature Review On Business Process Management, Business Process Reengineering, And Business Process Innovation, Abhijith Anand, Samuel Fosso Wamba, Denis Gnanzou
Faculty of Engineering and Information Sciences - Papers: Part A
Business process management (BPM), business process reengineering (BPR), and business process innovation (BPI) have been the primary strategies adopted by several organizations to manage their business successfully along with IT. In the last few years, the concept of BPM, BPR, and BPI has been a hot topic among the IS community, which is evident in the degree of literatures devoted to it. Due to the dynamic nature of this research area, this paper aims to add knowledge to the existing ones by answering (1) what is the current level of development on BPM, BPR, and BPI within AIS basket of …

Confinement Effect Of Frp And Transverse Steel On Retrofitting Square Concrete Columns, Le V. Doan, Xu Lei, Muhammad N. S Hadi, Thong M. Pham
Faculty of Engineering and Information Sciences - Papers: Part A
This study presents an experimental investigation into strain distribution of Fibre-Reinforced Polymer (FRP) in FRP-confined concrete columns with internal steel reinforcement under concentric and eccentric loading conditions. A total of nine reinforced concrete columns were cast and tested. Three of them were square in cross-section while the others were originally square but were shape-modified into circular columns with four pieces of segmental circular concrete covers and confined with three layers of CFRP. The nominal compressive strength of the segmental concrete covers was 40 MPa and 80 MPa. All columns were tested under concentric load, 25 mm or 50 mm eccentric …
Operations Strategy Processes: How Significant Are They?, Senevi Kiridena, Kalinga Jagoda, Howard Lin
Operations Strategy Processes: How Significant Are They?, Senevi Kiridena, Kalinga Jagoda, Howard Lin
Faculty of Engineering and Information Sciences - Papers: Part A
Ongoing challenges associated with the implementation of formally developed strategies call for studying the functional level strategy processes from fresh perspectives. This paper presents evidence drawn from the Canadian oil and gas industry towards establishing the statistical significance of alternative operations strategy processes and organisational contextual factors. The analysis discerned four strategy process configurations representing singular and multiple combinations of three strategy process modes identified in previous qualitative studies. The findings will help advance the understanding of operations strategy processes and may contribute to theory building, as the evidence was drawn from a relatively large sample of data representing an …

A Maximum Principle For Optimal Control Of Stochastic Evolution Equations, Kai Du, Qingxin Meng
A Maximum Principle For Optimal Control Of Stochastic Evolution Equations, Kai Du, Qingxin Meng
Faculty of Engineering and Information Sciences - Papers: Part A
A general maximum principle is proved for optimal controls of abstract semilinear stochastic evolution equations. The control variable and linear unbounded operators act in both drift and diffusion terms, and the control set need not be convex. Read More: http://epubs.siam.org/doi/abs/10.1137/120882433

University of Wollongong GIS-based Landslide Inventory has been expanded to facilitate reliable modeling of landslide susceptibility and hazard zonation over the wider Sydney Basin area. Landslide inventory development is underway after designing a state of the art inventory structure following a comprehensive international literature review. The alphanumerical as well as spatial data bases of landslides have been updated after field verification of landslides in Sydney and Newcastle as the stepping stone for the wider Sydney Basin area landslide susceptibility model development. In the lead up to this, landslide susceptibility modeling in two smaller sub-regions of Sydney (Wollongong Local Government Area …
